Effect of Jingui Shenqiwan on Diabetic Osteoporosis in Mice via AGEs/RANKL/NF-κB Pathway Based on Theory of "Kidneys Governing Bones" / 中国实验方剂学杂志

ObjectiveTo investigate the effect of Jingui Shenqiwan on diabetic osteoporosis （DOP） in mice by regulating the advanced glycation end products （AGEs）/receptor activator of nuclear factor-κB ligand （RANKL）/nuclear factor-κB （NF-κB） signaling pathway based on the theory of "kidneys governing bones". MethodForty 6-week-old male and female skeletal-muscle-specific， dominant negative insulin-like growth factor-1 receptor （MKR） mice were selected and fed on a high-fat diet for eight weeks to establish the DOP model. The model mice were randomly divided into a model group， low- and high-dose Jingui Shenqiwan group （1.3， 2.6 g·kg-1）， and an alendronate sodium group （0.01 g·kg-1）， with 10 mice in each group. Additionally， 10 FVB/N mice of the same age were assigned to the normal group. The corresponding drugs were administered orally to each group once a day for four weeks. After the administration period， fasting blood glucose （FBG） measurement and oral glucose tolerance test （OGTT） were conducted. Kidney function and kidney index were measured. Renal tissue pathological changes were observed through hematoxylin-eosin （HE） and Masson staining. Immunohistochemistry was performed to assess the protein expression levels of AGEs， phosphorylated NF-κB （p-NF-κB）， and RANKL in renal tissues. Western blot analysis was conducted to measure the expression of proteins related to the AGEs/RANKL/NF-κB signaling pathway， osteoprotegerin （OPG）， and Runt-related transcription factor 2 （RUNX2） proteins in femoral bone tissues. ResultCompared with the normal group， mice in the model group exhibited significantly increased FBG （P<0.01）， trabecular bone degeneration， abnormal bone morphological parameters， significantly increased area under the curve （AUC） of OGTT （P<0.01）， enlarged kidney volume， significantly increased kidney function indicators and kidney index （P<0.01）， disrupted renal glomeruli and renal tubule structures， significantly increased expression of AGEs， RANKL， and p-NF-κB/NF-κB in renal tissues （P<0.05）， and significantly decreased expression of OPG and RUNX2 in femoral bone tissues （P<0.01）. Compared with the model group， mice in the Jingui Shenqiwan groups showed a significant decrease in OGTT AUC （P<0.01）. Histopathological analysis revealed alleviated structural lesions in renal glomeruli and renal tubules. Furthermore， the expression of AGEs， RANKL， and p-NF-κB/NF-κB in renal tissues was significantly reduced （P<0.05， P<0.01）， and the expression of RUNX2 and OPG in femoral bone tissues was significantly increased （P<0.05， P<0.01）. ConclusionJingui Shenqiwan can improve kidney function and downregulate the AGEs/RANKL/NF-κB signaling pathway to inhibit inflammatory reactions， thereby alleviating the symptoms of DOP in mice， demonstrating a therapeutic effect on DOP from the perspective of the kidney.

The effects of high-intensity interval training on the renin-angiotensin system in spontaneously hypertensive rats / 中华物理医学与康复杂志

Objective:To observe any effect of high-intensity interval training on the blood pressure and renal function of Wistar-Kyoto rats modeling spontaneous hypertension (SHR) and to explore the mechanism of the renal renin-angiotensin system′s (RAS′s) role in this process.Methods:Twenty male SHR were randomly divided into a sedentary group and an exercise group, each of 10. Another 10 Wistar-Kyoto rats formed a normotensive control group. The rats in the normotensive and hypertensive sedentary groups were fed quietly in their cage, while the hypertensive exercise group performed high-intensity interval training for 8 weeks. After the last exercise, blood pressure, renal function, the kidney levels of nitric oxide and interleukin-6 (IL-6) and the protein expressions of angiotensin converting enzyme (ACE), ACE2, angiotensin type 1 receptor (AT1R), AT2R and Mas receptor (MasR) were measured.Results:Compared with the normotensive group, the hypertensive sedentary group showed a significant increase in average blood pressure, IL-6, ACE and AT1R protein and the ratio of AT1R to AT2R. There was a significant decrease in the renal function, the average NO level and the expression of ACE2, AT2R and MasR protein. That group also showed a significant decrease in blood pressure, IL-6, ACE and AT1R protein expression and the AT1R: AT2R ratio compared with the hypertensive sedentary group, but a significant increase in renal function, average NO content and the expression of ACE2, AT2R and MasR protein.Conclusion:Eight weeks of high-intensity interval training has a protective effect on the kidneys by regulating the renin-angiotensin system, at least in rats.

Paraquat-induced lung fibrosis and multiorgan failure: A case report from North India

Paraquat is a herbicide which is widely used by agricultural communities worldwide. It is extremely toxic for humans and ingestion of as less as 30 mL of 20%–24% concentration is usually lethal. The lack of an effective antidote is a concern due to the fatal outcomes associated with ingestion of paraquat. Herein, we are presenting a case of fatal paraquat poisoning in a young male from a center in India. The clinical course was complicated by liver, renal, and lung injury. We also describe its mechanism of toxicity, clinical features, and newer strategies being tried for treatment.

Awareness of Intravenous Contrast Media Effects on Renal Function in Saudi Arabia- An Observational Study.

Intravenous contrast media (IVCM) are routinely used in different imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), but can cause adverse effects on renal function. This study aims to evaluate the level of awareness of IVCM and their effects on renal function among members of the general public visiting King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia. MethodsAn observational cross-sectional study design was used. It was conducted in September 2018 on participants aged ≥18 years who completed an electronic self-administered questionnaire to assess their knowledge of the adverse renal effects of IVCM. Data was analyzed using descriptive and inferential statistics. Chi-squared test was used to evaluate the level of knowledge among residents regarding the possible adverse renal events that can be caused by IVCM. ResultsMost participants (56.8%) had no knowledge of IVCM and were unable to recognize the risk factors associated with IVCM and their potential impact on the kidneys. Social media was the most chosen source of information among those who had variable degrees of awareness. A statistically significant association was found between the educational level and degree of knowledge about the importance, application, and adverse events of IVCM. Most of the respondents lacked knowledge of the risk factors associated with contrast-induced nephropathy. ConclusionsParticipants generally had limited knowledge about IVCM and the associated risk factors. Educational programs could be utilized to improve awareness and understanding.

Anatomical And Embryological Study Of Renal Hilum

Introduction: As per standard text, the anteroposterior topographical arrangement of renal hilar structures are:vein-artery-renal pelvis. However, hilar variations are very common. Aim: The present study intends to increaseawareness of possible variations in the hilar anatomy as they are of immense importance in invasive renalinterventions.Materials and methods: A careful dissection of 51 embalmed cadaveric kidneys was carried out for the propervisualization of renal hilar structures and their relations were clearly defined.Observations and Results: Enormous renal hilar variation was observed. We classified these renal variations in8 different patterns. Normal hilar arrangement was seen in 25.5% kidneys and in 74.5% cases this arrangementis disturbed. 43.1% kidneys demonstrated presence of retropelvic structures. Anterior and posterior tributariesof renal vein were displayed in 9.8% of casesConclusion: Knowledge of the pattern of renal hilar structures is of great importance in the interventionalradiological & laparoscopic renal surgeries thereby reducing the risk of vascular complications.

Curcumin protects remote organs against injury that is caused by intestinal ischemia and reperfusion

In addition to several local pathophysiological consequences, intestinal injury that is caused by ischemia and reperfusion can result in the development of lesions in remote organs. Curcumin has therapeutic potential because of its antiinflammatory and antioxidant effects. The present study evaluated the effects of curcumin on oxidative and inflammatory parameters in the liver and kidneys in rats that were subjected to intestinal ischemia and reperfusion. The rats were subjected to 45 min. of ischemia followed by 7 days of reperfusion and treated daily with 60 mg kg-1 curcumin. The liver and kidneys were collected, weighed, and biochemically analyzed. Intestinal ischemia and reperfusion increased levels of lipid hydroperoxide (LOOH), decreased levels of reduced glutathione (GSH), and increased the enzymatic activity of superoxide dismutase (SOD), glutathione S-transferase (GST), and myeloperoxidase (MPO) in the liver. Intestinal ischemia and reperfusion decreased kidney weight and increased GST activity in the kidneys. Curcumin prevented these changes in the liver and kidneys. Intestinal ischemia and reperfusion mainly affected the liver, promoting inflammation and oxidative stress. The kidneys underwent repair much earlier than the liver, in which they did not present alterations of MPO or main parameters of oxidative stress after 7 days of reperfusion. Treatment with curcumin had beneficial effects, ameliorating or even preventing injury that was caused by intestinal ischemia and reperfusion in the liver and kidneys in rats

Renal myxoboliosis of Metynnis hypsauchen in the Brazilian Amazon: morphological and histopathological aspects

In their natural habitat, fish are constantly threatened by icthyoparasites, notably those from the Phylum Cnidaria, Hatschek, 1888, represented by species of the Myxozoa, responsible for infections in fish that cause complications to their health that can lead to death. Among these parasites, the genus Myxobolus Butschli, 1882 is responsible for the largest number of infections described in fishes from the Americas. This study describes the morphological and histopathological aspects of parasitism by Myxobolus sp. in specimens of Metynnis hypsauchen, obtained from the Capim river, in the municipality of Ipixuna do Pará, Pará, Brazil. During the months of August and March, 2018, 20 animals were captured, euthanized and autopsied. With the aid of a stereomicroscope an external and internal investigation was performed on the animals for the purpose of finding lesions or parasitic cysts, followed by confirmation of infection in Light Microscopy (ML). Cysts and Fragments from parasitized tissues were processed using techniques for histology and Scanning Electron Microscopy (SEM). For histology they were stained with Hematoxylin-Eosin (H-E) and Ziehl-Neelsen and for SEM Micrographs were captured, using equipment from the Museu Paraense Emílio Goeldi. The prevalence of parasitism was 60% (12/20) of the specimens, and the cysts were in the epithelium and lumen of the renal tubules, causing histopathological changes. The characteristics of the parasite spores are those associated with the genus Myxobolus, with an ellipsoid format, two polar capsules and a sporoplasm region. It was possible to confirm a high parasite load of Myxobolus, with compromised renal functions. This study is the first to describe Myxospore in Metynnis hypsauchen.

Introduction: Orofacial clefts are important congenital malformations of the lip, palate, or both caused by complex genetic and environmental factors. Aims and Objectives: The present study aims to highlight the phenotypic heterogeneity of trisomy 13 mosaicism. Material and Methods: We present one clinical case of a 30-year-old, Caucasian woman who is pregnant for the first time. Techniques of work study: anamnesis, clinical examination, serological tests for Toxoplasmosis, Rubeola, CMV and Herpes, ultrasound examination at 20 weeks gestation with General Electric Echographe Voluson E10 BT18, amniocentesis, fetal chromosome analysis and genetic counseling. Results: Ultrasound examination showed a viable singleton fetus with intra-uterine growth restriction, oligohydramnios, bilateral cleft lip and cleft palate, hypoplastic nasal bone and bilateral polycystic kidneys. Amniocentesis was done, and the fetal chromosomal analysis revealed a fetus with 46, XY/47, XY,+13 mosaic karyotype. After a complex genetic counselling the parents opted, to terminate the pregnancy. The autopsy confirm the prenatal ultrasound diagnosis. Conclusion: Routine ultrasound examination during pregnancy and specific genetic testing are essential for the early prenatal detection of major structural fetal anomalies associated with rare genetic chromosome syndromes.

Biochemical, endocrine, and histopathological profile of liver and kidneys of sheep with pregnancy toxemia / Perfil bioquímico, endócrino e histopatológico do fígado e rins de ovelhas com toxemia na prenhez

The objective of the present study was to characterize the biochemical, hormonal, and mineral profile, and histopathology of the liver and kidneys, related to the severity of natural cases of pregnancy toxemia (PT) in sheep. A total of 45 sheep with PT were analyzed at the "Clínica de Bovinos", Campus Garanhuns-UFRPE. The animals were submitted to clinical examination, followed by the collection of blood and urine. A necropsy was performed on thirteen animals that died and a histopathological examination was performed on samples of liver and kidneys. Increased creatinine, urea, glucose, fructosamine, non-esterified fatty acids, β-hydroxybutyrate, cortisol, chlorine, amylase, aspartate aminotransferase, gamma-glutamyltransferase, and folic acid were found, whereas insulin, potassium, and total and ionizable calcium presented low values for the species. Total protein, albumin, globulin, sodium, magnesium, and vitamin B12 remained within the normal range. In the macroscopic analysis of the liver, it was possible to observe an increase in organ and border size, yellowish coloration and parenchyma that varied from firm to friable. Vacuolation of the hepatocytes and renal tubular cells was observed. Metabolic disorders in sheep associated with hepatic and renal lesions are more apparent in overweight animals. With the greater impairment in hepatic and renal function, the clinical prognosis of animals with a high body score should be considered reserved.(AU)

Analisou-se 45 ovelhas na Clínica de Bovinos, Campus Garanhuns-UFRPE, com TP. Foram submetidas ao exame clínico, seguido de coleta de sangue e urina. Treze animais que vieram a óbito foram necropsiados, nas amostras de fígado e rins realizou-se exame histopatológico. Revelou-se elevação de creatinina, ureia, glicose, frutosamina, ácidos graxos não esterificados, β-hidroxibutirato, cortisol, cloro, amilase, aspartato aminotransferase, gama glutamiltransferase e ácido fólico, enquanto insulina, potássio, cálcio total e ionizável apresentaram valores abaixo para os da espécie. A proteína total, albumina, globulina, sódio, magnésio e vitamina B12 mantiveram-se dentro da normalidade. Na análise macroscópica do fígado, pôde-se observar aumento de tamanho do órgão e dos bordos, coloração amarelada e parênquima que variava de firme a friável. Observou-se vacuolização dos hepatócitos e das células tubulares renais. Os transtornos metabólicos nas ovelhas associados às lesões hepáticas e renais são mais aparentes nos animais com sobrepeso. Com o maior comprometimento da função hepática e renal, o prognóstico clínico dos animais com escore corporal elevado há de ser considerado reservado.(AU)

A histopathological observation made on cystic kidneys obtained from human cadavers

Introduction: Cysts in the kidneys have been described as being heterogeneous, and occur due to hereditary,developmental and acquired disorders. They account for 6-8% of diseases that go for dialysis. Evaluating cysticdiseases is important for pathological diagnosis and treatment procedures for the patient.Objective: Present study aimed at finding the types of cysts prevalent in human cadaveric kidneys by making ahistopathological observation. The study was made to review the incidence of cysts in kidneys and to find outwhat are the commonest types of cysts that are identified.Material and Methods: Thirty formalin fixed adult cadavers were used for the study. Twenty were male and tenwere female cadavers used for routine dissection and teaching purposes for the first year medical students in thedepartment of Anatomy, P.E.S Institute of Medical Sciences and Research. The kidneys were dissected out from thecadavers from both sides. The fat and fascia were removed carefully and first photographed for gross appearance,before handing the specimens to the department of pathology for further study by making sections.Results: Cystic kidneys were seen in seven cadavers out of the thirty cadavers. The other cadavers had no cystickidneys. The incidence of cysts has been calculated in this study as 23.3%. The normal kidneys were 76.6%. Inthree female cadavers unilateral cysts were seen in the right kidney. In male cadavers, one had unilateral cystand the remaining three presented with bilateral cystic kidneys. One among the four showed multiple bilateralcysts ranging from one to forty five cysts.Conclusion: From this study it is evident that cysts of the kidney may occur without disturbing the normalfunctioning of the kidneys. The incidence of multiple cysts was more in males than in females. No of cysts weremore in the right than in the left kidneys. For a person to lead a normal life one fifth of the kidney is sufficient ifit functions normally.

Posterior urethral valves (PUV) are the most common cause of lower urinary tract obstruction in the male child with broad spectrum of clinical presentation, disease severity and associated sequelae. Methods: Baseline investigations included pre fulguration blood renal profile, radiological (DTPA) investigation followed by post fulguration blood renal profile and radiological investigation. The outcome has been studied by the analysis of the biochemical markers & GFR & statistical tests shall be applied where ever necessary Improvement in quality of life in terms of dribbling, enuresis, pant wetting, school dropouts, growth & development. Results: The mean urea, Hb and creatinine level at different interval was non- significant (P> 0.05). The most common case of USG was B/l HDN (5) and B/L hydronephrosis (5). Conclusion: Aggressive surgical treatment is better policy to treat the patients with PUV. Urine cultures should be done in the follow up of PUV patients to prevent the recurrent UTI as it adversely effects the kidneys.

The effect of aerobic endurance exercise on renal fibrosis and the expression of TGF-beta 1 and E-cadherin in aged mice / 中华物理医学与康复杂志

Objective@#To explore the effect of aerobic endurance exercise on renal fibrosis in elderly mice and its possible mechanism.@*Methods@#Thirty-six healthy, male C57 mice were sorted into a young control group (2 months old), a senile control group (19 months old) and a senile exercise group (also 19 months old). The senile exercise group underwent aerobic endurance exercise for 7 weeks. Then all of the mice were sacrificed and any changes of in their renal tissues were recorded, especially the expression of fibrosis indicators using HE staining, Sirius red staining, RT-PCRs and immunohistochemical methods.@*Results@#Collagen fibers deposited in the kidney tissue of the senile groups were significantly more numerous than in the young control group, but their number had decreased significantly after the exercise.@*Conclusion@#Aerobic endurance exercise can inhibit collagen deposition and delay the formation of renal fibrosis, at least in rats. This may be related to its inhibition of TGF-β1 and α-SMA expression and up-regulation of E-cadherin expression.

Occurrence of Paratanaisia spp. Freitas, 1951 in a domiciled cockatiel (Nymphicus hollandicus, Psittaciformes: Cacatuidae) / Ocorrência de Paratanaisia spp. Freitas, 1951 em calopsita (Nymphicus hollandicus, Psittaciformes: Cacatuidae) domiciliada

Abstract Digenetic eucotylids of the Paratanaisia genus are widely reported parasites of the avian renal system. The infection, commonly reported in free-living and zoo-housed birds, is described for the first time in a domiciled bird, a cockatiel kept as pet bird with free access to the yard outdoors. The bird was received at Veterinary Hospital, where clinical and radiographic evaluations suggested a case of heavy-metal poisoning. Although the bird received supportive care and a chelating agent, it died the next day. The necropsy showed friable kidneys and congestion of blood vessels in structures such as the skin, proventriculus, brain, and skullcap. The histopathological evaluation of the kidneys revealed multifocal hemorrhages, commonly found in cases of heavy-metal poisoning. Parasitic structures similar to those of the digenean trematodes Paratanaisia spp. were also observed inside dilated collecting ducts, which presented epithelial cell flattening and vacuolization. There was compression of adjacent tissue and discrete fibrotic areas. In the presence of intermediate hosts in the yard, the synanthropic nature of some wild free-living birds could make them a source of trematodes infection and dissemination for pet birds. Conversely, the infected cockatiel could also have served as a reservoir and carrier of trematodes to wild free-living birds.

Resumo Eucotilídeos digenéticos do gênero Paratanaisia são amplamente descritos como parasitas do trato urinário de aves. A infecção, comumente relatada em aves de vida livre e em zoológicos, é descrita pela primeira vez em uma ave domiciliada, uma calopsita mantida como ave de companhia com livre acesso ao jardim externo. A ave foi recebida no Hospital Veterinário onde avaliações clínicas e radiográficas sugeriram um quadro de intoxicação por metal pesado. Embora tenha recebido tratamento de suporte e agente quelante a ave veio a óbito no dia seguinte. A necropsia demonstrou rins de consistência friável e congestão dos vasos sanguíneos da pele, proventrículo, cérebro e calota craniana. A avaliação histopatológica dos rins revelou hemorragias multifocais comumente observadas em intoxicação por metais pesados. Estruturas parasitárias similares àquelas observadas em Paratanaisia spp. foram observadas no interior de ductos coletores dilatados, os quais apresentavam achatamento e vacuolização de células epiteliais. Havia compressão do tecido adjacente e discretas áreas de fibrose. Na presença de hospedeiros intermediários no jardim, a condição sinantrópica de algumas aves de vida livre poderia torná-las fonte de infecção e disseminação de trematódeos para aves domiciliadas. Em contrapartida, a calopsita infectada poderia também servir como reservatório e carreador de trematódeos para aves de vida livre.

Solitary functioning kidney in children: clinical implications / Rim solitário em funcionamento em crianças: implicações clínicas

ABSTRACT Introduction: Children with solitary functioning kidney (SFK) are prone to develop long term problems, which are not well represented in the literature. The extent to which the presence of associated congenital anomalies of kidney and urinary tract (CAKUT) further de-stabilize renal function is to be addressed. Objective: This study was conducted to evaluate the etiology, presentation, presence of CAKUT, and renal damage in children with SFK. Methods: All children with SFK who presented to the department of pediatric surgery from March 2014 to May 2016 were included in the study. Children with malignancy were excluded from the study. Results: Of the 20 patients with SFK, 14 (70%) had primary SFK (8 with agenesis and 6 with multicystic dysplastic kidney), 6 (30%) belonged to secondary SFK group, among them 3 had pelviureteric junction obstruction, 2 had posterior urethral valves and 1 had vesicoureteric reflux. Eight (40%) had associated CAKUT, 4 (20%) were asymptomatic while 8 (40%) had UTI and 6 (30%) had hypertension. Ten (50%) patients had reduced glomerular filtration rate (GFR) suggesting compromised renal function. Conclusion: Children with SFK have high morbidity especially when associated with ipsilateral CAKUT. Long-term periodical follow up is essential in these patients to improve clinical outcome.

RESUMO Introdução: Crianças com rim solitário funcional (RSF) tendem a desenvolver problemas de longo prazo, que não são bem representados na literatura. Devemos abordar o quanto a presença de malformações congênitas do rim e do trato urinário (CAKUT) desestabiliza ainda mais a função renal. Objetivo: Este estudo foi realizado para avaliar a etiologia, apresentação, presença de CAKUT e dano renal em crianças com RSF. Métodos: Todas as crianças com RSF que se apresentaram no departamento de cirurgia pediátrica de março de 2014 a maio de 2016 foram incluídas no estudo. Crianças com doença maligna foram excluídas do estudo. Resultados: dos 20 pacientes com RSF, 14 (70%) tinham RSF primário (8 com agenesia e 6 com rim displásico multicístico), 6 (30%) pertenciam ao grupo RSF secundário, dentre eles 3 tinham obstrução da junção pelveuretérica, 2 tinham valvas uretrais posteriores e 1 refluxo vesico-uretral. Oito (40%) tinham ACRTU associado, 4 (20%) estavam assintomáticos, enquanto 8 (40%) tinham ITU e 6 (30%) tinham hipertensão. Dez (50%) pacientes apresentaram redução da taxa de filtração glomerular (TFG), sugerindo comprometimento da função renal. Conclusão: Crianças com RSF apresentam alta morbidade, especialmente quando associadas à CAKUT ipsilateral. O acompanhamento periódico a longo prazo é essencial nesses pacientes para melhorar o resultado clínico.

Establishment method of a rat model of renal ischemia-reperfusion injury by clamping the bilateral renal pedicles through backside and retroperitoneal incision / 中国比较医学杂志

Objective To explore a method to prepare a model of renal ischemia-reperfusion injury, with mild injury to animals, simple and easy to operate and stable effectiveness. Methods Healthy SD male rats were randomly divided into normal group (group C), sham-operated group (group S) and experimental group (IR group). Rats in the experimental group received a median incision in the middle of the back skin. Through the muscle fascia of each side on the back into the bilateral retroperitoneal space, the bilateral renal pedicles were separated, and closed for 50 min with a mini artery clamp without injury, and then the blood perfusion of the bilateral renal pedicles was resumed by releasing the mini artery clamp. Except that the rats of sham operation group were not blocked the renal pedicle, the rest of the operating steps were consistent with the experimental group. The normal group rats were not treated except for anesthesia. To observe the condition of the rats, serum creatinine (SCr), blood urea nitrogen (BUN) and pathologyical changes in the kidney tissues at 24 h after operating. Results Skin incision was 2. 24 ± 0. 27 cm in the group IR, the right incision of lumbar dorsal fascia and muscle was 1. 36 ± 0. 21 cm, and the left incision was 1. 36 ± 0. 24 cm. The operation time was 3. 30 ± 0. 37 min from incising skin to clamping the bilateral kidney pedicles. The successful rate of model preparation reached 95% in the IR group. Compared with the groups C and S, the levels of SCr and BUN were remarkably increased in the IR group (P ＜0. 01), and renal tubular necrosis scores were also significantly increased (P＜ 0. 05). Conclusions The rat model of renal ischemia-reperfusion injury is established by clamping bilateral renal pedicles via dorsal retroperitoneal incision. This surgical procedure is stable and simple, with a high success rate and small incision, less bleeding, and minimal animal injury.

Ultrassonografia modo B e Doppler na avaliação renal de cães submetidos à tomografia computadorizada após administração intravenosa de diferentes meios de contraste iodado / B-mode and Doppler ultrasonography in the renal evaluation of dogs undergoing computed tomography after intravenous administration of different iodinated contrast media

A nefropatia induzida por contraste (NIC) é uma doença de caráter agudo, secundária à administração intravascular de meios de contraste iodado (MCI). Dentre os mecanismos fisiopatológicos desta enfermidade destacam-se a vasoconstrição intrarrenal prolongada, consequente redução da perfusão renal, hipóxia e isquemia medulares, associada ao dano tubular renal devido à citotoxicidade do contraste. Frente à existência de poucas informações relacionadas a estes mecanismos na literatura médico-veterinária, objetivaram-se comparar os efeitos renais da administração intravenosa de MCI não iônicos de diferentes osmolaridades, em grupos de cães com fatores de risco para o desenvolvimento da NIC, por meio das avaliações ultrassonográficas modo B, Doppler colorido, de amplitude e pulsado, pareada aos exames laboratoriais, a fim de estimar indiretamente o potencial nefrotóxico de cada contraste. Constituíram-se dois grupos de acordo com o MCI utilizado: o grupo GIH [11 cães receberam iohexol (baixa osmolaridade)] e o grupo GID [sete cães receberam iodixanol (isosmolar)]. Administrou-se a dose de 600mgI/kg/IV em ambos. Avaliaram-se os seguintes aspectos renais antes da administração do MCI (momento basal) e após 1h30min, 24 horas e 48 horas: morfometria (comprimento e volume), morfologia, ecogenicidade cortical e perfusão renais e resistência vascular intrarrenal (índices hemodinâmicos de resistividade e pulsatilidade). Realizou-se ainda exame de urina e se mensuraram as razões gama-glutamil transferase:creatinina (GGT:C) e proteína:creatinina (RPC) urinárias e a concentração sérica de creatinina. Os grupos apresentaram comportamentos similares para comprimento, volume, RPC, exame de urina e creatinina sérica. Em relação ao índice de pulsatilidade (IP), os grupos apresentaram comportamentos não similares, mas sem diferenças significantes entre o momento basal e os demais. Para o índice de resistividade (IR) e a razão GGT:C urinária, os grupos revelaram comportamentos não similares e se constataram aumentos significantes do IR e da razão GGT:C urinária no período de 1h30min após a administração do contraste, somente para o grupo que recebeu iohexol. Concluiu-se que o IR pode ser utilizado para monitorar a hemodinâmica intrarrenal, visto que junto com a razão GGT:C urinária, demonstrou a existência de maior potencial nefrotóxico do iohexol, quando comparado ao iodixanol. Dessa forma, considera-se o uso do iodixanol, opção favorável para cães com fatores de risco para o desenvolvimento da NIC.(AU)

Contrast-induced nephropathy (CIN) is an acute disease, secondary to intravascular administration of iodinated contrast media (ICM). The most important mechanisms of this nephropathy are intrarenal prolonged vasoconstriction, medular hypoxia, and ischemia associated with renal tubular damage due to contrast cytotoxicity. Owing to the limited information available in veterinary literature regarding these mechanisms this study aims to compare the renal effects of intravenous administration of two nonionic ICM of different osmolarities in groups of dogs with risk factors for CIN development, by using a B-mode, color, power- and pulsed-wave Doppler ultrasonography, and other laboratory tests, in order to indirectly estimate the nephrotoxic potential of each contrast. The following two groups were established according to the nonionic ICM used: the GIH group [11 dogs administered iohexol (low osmolarity)] and the GID group [seven dogs administered iodixanol (iso-osmolarity)]. Both the groups were administered the same dose (600mgI/kg/IV). The following renal aspects were evaluated before administration of ICM (baseline) and after 1h30min, 24h, and 48h: renal morphometry (length and volume), renal morphology, cortical echogenicity, renal perfusion, and intrarenal vascular resistance (resistive and pulsatility indices); in addition, urinalysis was performed, and urinary gamma-glutamyl transferase:creatinine ratio (GGT:C), urinary protein:creatinine ratio (UPC), and serum creatinine were also measured. Both groups showed similar characteristics with respect to the length, volume, UPC ratio, urinalysis, and serum creatinine levels. No similarity was observed with respect to the pulsatility index (PI) in both the groups and there were no significant differences between baseline and 1h30min, 24h and 48h time points. With respect to the IR and urinary GGT:C, both groups showed no similarity, and significant increases were observed in the resistive index (RI) and urinary GGT:C only in the GIH group, 1h30min after contrast administration. In conclusion, RI can be used to monitor intrarenal hemodynamics, and along with the urinary GGT:C, revealed that iohexol had higher nephrotoxic potential than iodixanol. Thus, iodixanol is considered a favorable option for dogs with risk factors for CIN development.(AU)

Características ultrassonográficas de fígado, vesícula biliar, rins, vesícula urinária e jejuno em coelhos jovens e adultos / Ultrasound features of liver, gallbladder kidneys, urinary bladder and jejunum in young and adult rabbits

O presente trabalho descreveu características e comparou mensurações do fígado, vesícula biliar, rins, vesícula urinária e jejuno de coelhos da raça Nova Zelândia Branco (NZB) jovens e adultos. O grupo dos jovens foi composto por 39 coelhos de ambos os sexos (20 machos e 19 fêmeas), desmamados aos 30-31 dias de idade, sendo as avaliações realizadas aos 35, 56 e 77 dias de idade. O grupo dos adultos foi composto por 23 fêmeas e 15 machos, com idade superior a 6 meses, sendo realizada uma avaliação ultrassonográfica por animal. O exame consistiu na avaliação do fígado, vesícula biliar, rins direito e esquerdo, jejuno e vesícula urinária. Todos os animais foram pesados antes dos exames. O peso médio dos animais aumentou (p<0,05) dos 35 dias até a idade adulta. Tanto nos adultos quanto nos jovens, o fígado apresentou-se predominantemente isoecogênico ao rim direito e com textura homogênea. A vesícula biliar apresentou-se em formato ovoide alongado, variando de piriforme à amendoado, com conteúdo anecogênico, não sendo visível em 2,6% dos coelhos jovens e em 26,3% dos adultos. O comprimento e a largura da vesícula biliar nas idades de 35, 56, 77 dias e adultos foram: 1,06 e 0,39; 1,44 e 0,53; 1,41 e 0,58; 1,57 e 0,67cm, respectivamente. Considerando jovens e adultos, as mensurações da vesícula biliar e dos rins esquerdo e direito apresentaram correlação positiva (p<0,05) com o peso. Os rins apresentaram-se no formato de elipse e com superfície regular, com aumento (p<0,05) dos 35 dias à idade adulta. Houve correlação positiva (p<0,05) entre os volumes renais direito e esquerdo. A descrição da vesícula urinária mais encontrada (86%) foi a com conteúdo anecogênico, com pequenas estruturas ecogênicas livres no lúmen, tanto em jovens quanto em adultos. Não houve diferença (p>0,05) da espessura das camadas do jejuno entre as idades, apresentando média de 0,23 cm para todos os animais. Estes são os primeiros dados brasileiros de características ultrassonográficas de fígado, vesícula biliar, rins, jejuno e vesícula urinária para coelhos NZB de 35, 56 e 77 dias de vida e adultos.(AU)

This study described characteristics and measurements of the liver, gallbladder, kidney, urinary bladder and jejunum of young and adults New Zealand White (NZW) rabbits. The young rabbits's group was composed of 39 rabbits of both sexes (20 males and 19 females), weaned at 30-31 days of age, and the evaluations carried out at 35, 56 and 77 days of age. The adults group was composed of 23 females and 15 males, with more than 6 months of age, and one ultrasonographic evaluation per animal. The exam consisted in the evaluation of liver, gallbladder, right and left kidneys, jejunum and urinary bladder. All the animals were weighed before the evaluations. The average weight increased (p<0.05) from 35 days to adults. Both in adult and in young rabbits, the liver presented predominantly isoechogenic in relation of right kidney and with homogeneous texture. The gallbladder had an elongated ovoid shape, ranging for pear-shaped to almond, with anechogenic content, not being visible in 2.6% of young rabbits and 26.3% of adults. The length and width were 1.06 and 0.39; 1.44 and 0.53; 1.41 and 0.58; 1.57 and 0.67cm, respectively at 35, 56, 77 days and adults. For young and adults rabbits, the gallbladder and the left and right kidneys were positively correlated (p<0.05) with weight. The kidneys had an ellipse shape with smooth surface, increasing (p>0.05) from 35 days to adulthood. There was a positive correlation (p<0.05) between the right and left kidney volumes. The description of urinary bladder more frequently (86%) observed was anechogenic content, with small free echogenic structure within the lumen, both in young and in adult rabbits. There was no difference (p>0.05) in the thickness of the layers of the jejunum among ages, with the mean of 0.23cm for all animals. With the results, the first Brazilian ultrasonographic data for liver, gallbladder, kidney, jejunum and urinary bladder were defined to NZW rabbits in 35, 56 and 77days of life, as well as adults.(AU)

Normal Functioning Pelvic Lump Kidney: Isolated Anomaly - Radiological Evaluation.

There is wide spectrum of Mullerian dysgenesis presenting in different ways. Routine ultrasound done of a child for pain abdomen discovered a pelvic mass supero-posterior to the urinary bladder. This was diagnosed as fused pelvic kidneys by various cross sectional imaging modalities like Computerized tomography (CT) and Magnetic resonance imaging (MRI).We present a 4-years male child who was diagnosed as a case of “lump kidneys” by plain sonography coupled with color flow imaging (CFI). The entity usually falls in the common group of VATER (vertebral, anorectal malformation, esophageal and renal) anomalies. But our present case was having isolated anomaly and this entity is of a great rarity as seen in literature.

Occurrence of Paratanaisia spp. Freitas, 1951 in a domiciled cockatiel (Nymphicus hollandicus, Psittaciformes: Cacatuidae)

Abstract Digenetic eucotylids of the Paratanaisia genus are widely reported parasites of the avian renal system. The infection, commonly reported in free-living and zoo-housed birds, is described for the first time in a domiciled bird, a cockatiel kept as pet bird with free access to the yard outdoors. The bird was received at Veterinary Hospital, where clinical and radiographic evaluations suggested a case of heavy-metal poisoning. Although the bird received supportive care and a chelating agent, it died the next day. The necropsy showed friable kidneys and congestion of blood vessels in structures such as the skin, proventriculus, brain, and skullcap. The histopathological evaluation of the kidneys revealed multifocal hemorrhages, commonly found in cases of heavy-metal poisoning. Parasitic structures similar to those of the digenean trematodes Paratanaisia spp. were also observed inside dilated collecting ducts, which presented epithelial cell flattening and vacuolization. There was compression of adjacent tissue and discrete fibrotic areas. In the presence of intermediate hosts in the yard, the synanthropic nature of some wild free-living birds could make them a source of trematodes infection and dissemination for pet birds. Conversely, the infected cockatiel could also have served as a reservoir and carrier of trematodes to wild free-living birds.

Resumo Eucotilídeos digenéticos do gênero Paratanaisia são amplamente descritos como parasitas do trato urinário de aves. A infecção, comumente relatada em aves de vida livre e em zoológicos, é descrita pela primeira vez em uma ave domiciliada, uma calopsita mantida como ave de companhia com livre acesso ao jardim externo. A ave foi recebida no Hospital Veterinário onde avaliações clínicas e radiográficas sugeriram um quadro de intoxicação por metal pesado. Embora tenha recebido tratamento de suporte e agente quelante a ave veio a óbito no dia seguinte. A necropsia demonstrou rins de consistência friável e congestão dos vasos sanguíneos da pele, proventrículo, cérebro e calota craniana. A avaliação histopatológica dos rins revelou hemorragias multifocais comumente observadas em intoxicação por metais pesados. Estruturas parasitárias similares àquelas observadas em Paratanaisia spp. foram observadas no interior de ductos coletores dilatados, os quais apresentavam achatamento e vacuolização de células epiteliais. Havia compressão do tecido adjacente e discretas áreas de fibrose. Na presença de hospedeiros intermediários no jardim, a condição sinantrópica de algumas aves de vida livre poderia torná-las fonte de infecção e disseminação de trematódeos para aves domiciliadas. Em contrapartida, a calopsita infectada poderia também servir como reservatório e carreador de trematódeos para aves de vida livre.

Aumento renal bilateral como manifestação de leucemia linfocítica aguda / Bilateral renal increase as a manifestation of acute lymphocytic leukemia

As leucemias são o tipo mais frequente de câncer em crianças e adolescentes. A leucemia linfocítica aguda é a forma mais comum de leucemia na infância. A doença surge normalmente entre dois e quatro anos de idade, sendo incomum antes de um ano de vida. As manifestações mais comuns incluem febre, fadiga, letargia, dor óssea e articular. Em 50% dos casos, há hepato e/ou esplenomegalia e linfonodomegalias. Este relato de caso fala sobre uma menina de nove meses que foi levada à emergência do hospital por distensão abdominal, fraqueza em membros inferiores e constipação duas semanas antes. Apresentava massas abdominais endurecidas em flancos, abaulamento em região fronto-temporal direita e linfonodomegalias cervicais. A primeira impressão foi de nefroblastoma bilateral (Tumor de Wilms). A ecografia abdominal e a tTC de abdome mostraram aumento de volume renal bilateral e descartaram nefroblastoma. Em setor de oncologia pediátrica, foi realizada imunofenotipagem compatível com leucemia/linfoma linfoblástico B. No líquor havia 400 células p/uL com 81% de blastos. A avaliação neurológica e a RNM de crânio e neuro-eixo descartaram alteração que justificasse a paresia de membros inferiores. No décimo dia de tratamento, os rins já haviam reduzido até o limite superior da normalidade. O abaulamento da face já havia desaparecido. A paciente apresentou anemia, neutropenia, plaquetopenia e hipoalbuminemia severas. Ao final da indução, apresentou sepse fúngica e bacteriana evoluindo para choque séptico e parada cardiorrespiratória não responsiva às manobras de reanimação. Não foi realizado medulograma no final da indução por piora do quadro clínico e posterior óbito (AU)

Leukemias are the most frequent type of cancer in children and adolescents. Acute lymphocytic leukemia is the most common form of childhood leukemia. The disease usually arises between two and four years of age, being uncommon before one year of life. The most common manifestations include fever, fatigue, lethargy, bone and joint pain. In 50% of cases, there is hepatomegaly and/or splenomegaly and lymph node enlargement. This case report tells of a nine-month old girl who was taken to the hospital emergency room due to abdominal distension, weakness in the lower limbs, and constipation for two weeks. She had abdominal masses that were hardened on the flanks, bulging in the right fronto-temporal region and cervical lymph node enlargements. The first impression was bilateral nephroblastoma (Wilms tumor). Abdominal ultrasound and abdominal CT showed bilateral renal volume increase and ruled out nephroblastoma. In the pediatric oncology sector, immunophenotyping compatible with lymphoblastic leukemia/lymphoma was performed. In the CSF there were 400 cells/L with 81% blasts. Neurological evaluation and MRI of the skull and neuro-axis ruled out alterations justifying lower limb paresis. By the tenth day of treatment, the kidneys had already reduced to the upper limit of normal. The bulging of the face was gone. The patient presented severe anemia, neutropenia, thrombocytopenia and hypoalbuminemia. At the end of the induction, she presented fungal and bacterial sepsis evolving to septic shock and cardiorespiratory arrest unresponsive to resuscitation maneuvers. No myelogram was performed at the end of the induction due to worsening of the clinical picture and subsequent death (AU)
