Principais alterações em exames bioquímicos de cães domésticos na cidade de Formiga/MG de 2017 a 2021 / Main alterations in biochemical tests of domestic dogs in the city of Formiga/MG from 2017 to 2021

O uso de exames laboratoriais na clínica de pequenos animais é um importante recurso, principalmente quando se trata de exames bioquímicos que avaliam funções renais e hepáticas. Esses exames podem auxiliar não somente na descoberta de doenças e no direcionamento do seu tratamento, como também no estadiamento de patologias já diagnosticadas. Com base no exposto foi realizado um estudo transversale retrospectivo avaliando os valores absolutos e a frequência de exames bioquímicos realizados num laboratório de análises clínicas veterinárias de Formiga/MG. Foram avaliados os valores de Nitrogênio Ureico, Creatinina, AST, ALT, ALP, Gama GT, Glicose e Proteínas Totais e Frações. Foi visto que a maioria dos resultados se encontravam dentro dos valores de referência e que algumas enzimas precisam ser relacionadas com outras para resultados mais precisos.(AU)

The use of laboratory tests in small animal clinics is an important resource, especially when it comes to biochemical tests that assess kidney and liver functions. These exams can help not only in the discovery of diseases and in directing their treatment, but also in the staging of already diagnosed pathologies. Based on the above, a cross-sectional and retrospective study was carried out, evaluating the absolute values and the frequency of biochemical tests performed in a clinical veterinary analysis laboratory in Formiga/MG. Ureic Nitrogen, Creatinine, AST, ALT, ALP, GT Gamma, Glucose and Total Proteins and Fractions were evaluated. It was seen that most results were within reference values and that some enzymes need to be related with others for more accurate results.(AU)

Lipid profile and metabolic parameters of tilapia in the finishing phase in earth ponds or using biofloc technology

Tilapia is a species with great growth potential. Its production comes from a semi-intensive system, such as earthen ponds (EP). Recently, biofloc technology (BFT) appears as an option to intensify fish production. The objective of this work was to compare the organosomatic indices, biochemical parameters, and chemical composition of tilapia reared in EP and BFT. Fish were grown for 150 days, with an initial weight of ≅ 2 g and a final weight of ≅ 780 g. Thereafter, tissues and organs were collected to determine organosomatic indices and analyze biochemical parameters, fatty acid, and proximate composition. The carcass yield was higher for tilapia reared in EP than BFT. The production system did not affect the fish fillet yield. The other organosomatic parameters were higher for tilapia reared in BFT. Tilapia reared in EP showed higher content of crude protein and lipids in the fillet. In both production systems, there was no difference in the body lipid profile. Fish in BFT showed a higher concentration of glucose and ammonia in the muscle and amino acids in the liver. Fish reared in EP showed a higher concentration of lactate in the liver compared to those in BFT. In conclusion, the production system alters the metabolism of fish. The biofloc has a considerable amount of fatty acids, which can be considered in the formulation of diets for tilapia in this system.(AU)

Testes bioquímicos para identificação de leveduras na medicina veterinária - revisão de literatura / Biochemical tests to yeast identification in veterinary medicine - literature review / Pruebas bioquímicas para identificación de levaduras en la medicina veterinaria - revisión de literatura

As leveduras são fungos de importância à medicina veterinária por causarem doenças infecciosas em diferentes hospedeiros animais. A presente revisão de literatura teve como objetivo relatar os principais testes bioquímicos capazes de auxiliar na identificação de fungos leveduriformes de interesse veterinário e zoonótico. Para o levantamento bibliográfico, foram consideradas 48 publicações científicas selecionadas na área e indexadas nas principais bases de dados, entre os anos de 1988 e 2020. Como resultados, observou-se que oito provas são as mais empregadas na rotina micológica. Devido à baixa variabilidade morfológica das espécies leveduriformes, testes bioquímicos complementares são fundamentais na rotina laboratorial. A análise do perfil bioquímico de leveduras contribui na determinação taxonômica dos fungos a partir de reações químicas, visto que o metabolismo varia de acordo com a espécie, resultando em metabólitos distintos, os quais podem ser avaliados por diferentes provas. Conclui-se que a identificação fenotípica das leveduras é imprescindível no diagnóstico, prognóstico, tratamento e controle de doenças fúngicas e contribui para a manutenção da saúde animal.(AU)

Yeasts are fungi of importance to veterinary medicine because they cause infectious diseases in different animal hosts. This literature review aimed to report the main biochemical tests capable of assisting in the identification of yeast-like fungi of veterinary and zoonotic interest. For the bibliographical survey, 48 selected scientific publications in the area and indexed in the main databases, between the years 1988 and 2020, were considered. As a result, it was observed that eight tests are the most used in the mycological routine. Due to the low morphological variability of yeast species, complementary biochemical tests are fundamental in the laboratory routine. The analysis of the biochemical profile of yeast contributes to the taxonomic determination of fungi based on chemical reactions, since the metabolism varies according to the species, resulting in different metabolites, which can be evaluated by different tests. It is concluded that the phenotypic identification of yeasts is essential in the diagnosis, prognosis, treatment and control of fungal diseases and contributes to the maintenance of animal health.(AU)

Emulsifier in Diets with Different Alternative Lipid Sources: Effects on the Health of Japanese Quails

The present research aims to evaluate the inclusion of an emulsifying additive based on mono- and diglycerides of fatty acids in diets with different lipid sources, studying its effects on duodenum histology, biometry of the digestive and reproductive tract, and blood biochemical profile of Japanese quails. The study was carried out in the experimental aviary of the Federal University of Grande Dourados, Mato Grosso do Sul, Brazil. The experimental design was completely randomized, with diets in a 3x2 factorial design with three different lipid sources (soybean oil, poultry fat, and beef tallow), either supplemented or not with an emulsifier. The birds that received a diet composed of poultry fat and an emulsifying additive had a larger gizzard. Animals that received a diet containing an emulsifier, regardless of the lipid source, had greater heart weight. The duodenum of animals that received bovine tallow in their diet showed a greater height and villus:crypt ratio. Biochemical parameters were not affected by either the lipid source or the inclusion of emulsifier in quail diets. The biochemical blood profile of birds in treatments did not show significant changes among all diets used. The use of soybean oil, bovine tallow, and poultry fat with or without the inclusion of an emulsifier does not show changes in the health and development of the quails' organs, which also indicates that the health of Japanese quails in the laying phase is kept in good standards.(AU)

The role of purslane in modulating diverse effects of high fat diet on biochemical, histological, and molecular parameters of rats liver

Abstract Consuming a high-fat diet causes a harmful accumulation of fat in the liver, which may not reverse even after switching to a healthier diet. Different reports dealt with the role of purslane as an extract against high-fat diet; meanwhile, it was necessary to study the potential role of fresh purslane as a hypolipidemic agent. This study is supposed to investigate further the potential mechanism in the hypolipidemic effect of fresh purslane, by measuring cholesterol 7a-hydroxylase (CYP7A1) and low-density lipoprotein receptor (Ldlr). Rats were divided into two main groups: the first one is the normal control group (n=7 rats) and the second group (n=28 rats) received a high fat diet for 28 weeks to induce obesity. Then the high fat diet group was divided into equal four subgroups. As, the positive control group still fed on a high fat diet only. Meanwhile, the other three groups were received high-fat diet supplemented with a different percent of fresh purslane (25, 50 and 75%) respectively. At the end of the experiment, rats were sacrificed and samples were collected for molecular, biochemical, and histological studies. Current study reported that, supplementation of fresh purslane especially at a concentration of 75% play an important role against harmful effects of high-fat diet at both cellular and organ level, by increasing CYP7A1 as well as Ldlr mRNA expression. Also, there were an improvement on the tested liver functions, thyroid hormones, and lipid profile. Fresh purslane plays the potential role as a hypolipidemic agent via modulation of both Ldlr and Cyp7A, which will point to use fresh purslane against harmful effects of obesity.

Resumo O consumo de uma dieta rica em gordura causa um acúmulo prejudicial de gordura no fígado, que pode não reverter mesmo após a mudança para uma dieta mais saudável. Diferentes relatórios trataram do papel da beldroega como um extrato contra uma dieta rica em gordura; entretanto, foi necessário estudar o papel potencial da beldroega fresca como agente hipolipemiante. Este estudo pretende investigar mais profundamente o mecanismo potencial no efeito hipolipidêmico da beldroega fresca, medindo o colesterol 7a-hidroxilase (CYP7A1) e o receptor de lipoproteína de baixa densidade (Ldlr). Os ratos foram divididos em dois grupos principais: o primeiro é o grupo controle normal (n = 7 ratos) e o segundo grupo (n = 28 ratos) recebeu dieta rica em gorduras por 28 semanas para induzir a obesidade. Em seguida, o grupo de dieta rica em gordura foi dividido em quatro subgrupos iguais. Como, o grupo de controle positivo ainda se alimentava apenas com dieta rica em gordura. Enquanto isso, os outros três grupos receberam dieta rica em gordura suplementada com diferentes porcentagens de beldroegas frescas (25%, 50% e 75%), respectivamente. Ao final do experimento, os ratos foram sacrificados e amostras coletadas para estudos moleculares, bioquímica e histológicos. O estudo atual relatou que a suplementação de beldroegas frescas, especialmente a uma concentração de 75%, desempenha papel importante contra os efeitos prejudiciais da dieta rica em gordura em nível celular e orgânico, aumentando a expressão de CYP7A1 e Ldlr mRNA. Além disso, houve melhora nas funções hepáticas testadas, nos hormônios tireoidianos e no perfil lipídico. Beldroegas frescas desempenham papel potencial como agente hipolipemiante por meio da modulação de Ldlr e Cyp7A, o que apontará para o uso de beldroegas frescas contra os efeitos nocivos da obesidade.

Relationship of Linoleic and Alpha-Linolenic Acids on the Productive Performance and Serum Biochemical Profile of Japanese Quail Breeders

Linoleic (LA, 18:2) and alpha-linolenic (ALA, 18:3) acids are omega-6 and omega-3 polyunsaturated fatty acids considered essential to human and animal health. The optimum LA/ALA ratio for the production of fertile eggs in Japanese quail breeders has been little investigated. Thus, this study aimed to assess the effects of LA/ALA ratio on productive performance, egg quality, serum biochemical profile, body composition, and organ weight in Japanese quail. A completely randomized design was used. Birds were distributed into five treatments consisting of different LA/ALA ratios (1.48:1, 4.57:1, 7.63:1, 10.69:1, and 13.75:1), obtained by adding soybean (LA) and flaxseed (ALA) oils to the feed. Productive performance and egg quality were assessed in three cycles of 28 days each. At the end of the experiment, the birds were slaughtered and evaluated for biochemical profile, genital organ weights, and body composition. Data were subjected to analysis of variance and regression (p<0.05). LA/ALA ratio had no effect on productive performance or egg quality. Blood cholesterol in females and males and total triglycerides in females showed a quadratic response. Breeders fed the highest level of flaxseed oil (1.48:1) had the best serum levels of cholesterol and total triglycerides. Live weight and relative organ weights were not influenced by LA/ALA ratio. Differences in ash and crude protein levels were observed between groups, with LA increasing the deposition of these nutrients. It was concluded that LA/ALA ratio didn't affect productive performance or egg quality. However, based on the results of body composition, serum triglycerides, and cholesterol, it is recommended to use an LA/ALA ratio of 1.48:1 in diets.(AU)

Fertilidade e suscetibilidade à criopreservação espermática: avanços e desafios / Fertility and susceptibility to sperm cryopreservation: advances and challenges

Estudos sobre a fisiologia espermática demonstram que padrões de fertilidade e funcionalidade espermática pós-criopreservação possuem relação importante com a eficiência do metabolismo energético destas células, bem como com a sua capacidade de manter a homeostase oxidativa. Os conhecimentos sobre a relação entre perfil fisiológico de espermatozoides e fertilidade foram e, ainda estão sendo, aprimorados, com o uso de análises de perfis moleculares, com destaque para a metabolômica. As análises moleculares permitiram a identificação de classes de metabólitos importantes na fisiologia espermática, bem como de potenciais biomarcadores de fertilidade, inclusive em bovinos. No entanto, ainda não há disponível uma avaliação isolada capaz de estimar o padrão de fertilidade de amostras seminais. Há vários desafios a serem superados para a validação de biomarcadores de fertilidade, principalmente considerando-se as diferenças entre perfis metabólicos de raças distintas de touros e a heterogeneidade dos ejaculados. A superação destes desafios pode ser iniciada com um maior aproveitamento dos resultados já obtidos e futuros, com a aplicação de análises mais avançadas e com eficácia em elevado número de dados. Para tal, podem ser utilizados modelos estatísticos de inteligência artificial, cuja aplicação pode aumentar a acurácia das observações obtidas, bem como aproximá-las da aplicação pelo setor de produção animal.(AU)

Studies on sperm physiology demonstrate that fertility outcomes and sperm post-cryopreservation have an important relation with sperm energy metabolism efficiency and ability to maintain oxidative homeostasis. Knowledge on sperm physiology has been enhanced, continually, with the application of molecular profiling analysis, focusing on metabolomics. Molecular analysis allowed the identification of important classes of metabolites in sperm physiology, as well as potential fertility biomarkers, including in bovine. Despite all developments, there is still no isolated assessment available capable of estimating fertility on sperm samples. There are several challenges to be overcome for the validation of fertility biomarkers, especially considering the metabolic profiles differences between bull breeds and the ejaculate heterogeneity. Overcoming these challenges could start with the application of more advanced and effective data analysis from research database already obtained, as well as future ones. To this end, statistical models of artificial intelligence can be used, whose application can increase the accuracy of the observations obtained, as well as bringing them closer to the application by the animal production sector.(AU)

Blood biochemical parameters of lambs fed diets containing cactus cladodes / Parâmetros bioquímicos sanguíneos de cordeiros alimentados com dietas contendo palma forrageira

This study aimed to evaluate the effects of partial replacement (750g/kg) of Tifton hay by two cactus cladodes (Nopalea or Opuntia) on the metabolic profile of lambs. Thirty-six uncastrated male Santa Inês lambs (22.0±2.9kg initial body weight) were distributed in a completely randomized design, with three treatments and 12 repetitions. The animals were fed a control diet (Tifton hay as exclusive roughage), Miúda cactus cladodes-based diet or Orelha de Elefante Mexicana (O.E.M.) cactus cladodes-based diet. Blood samples were collected one day before (baseline) and 45 days after the introduction of the tested diets. The Miúda cactus cladodes caused an increase (P=0.055) in the serum activity of the gamma-glutamyl transferase enzyme (53.66U/L) and in the blood content of glucose and fructosamine. The O.E.M. cactus cladodes caused lower (P=0.038) serum cholesterol content (41.33mg/dL). Regardless of the variety, there was a decrease (P=0.001) in the serum content of indirect bilirubin, urea, and sodium, and increase in the serum magnesium concentration. The partial replacement of the Tifton hay by Miúda or O.E.M. cactus cladodes in lamb feeding increases the enzyme activity, indicating liver and/or kidney changes, but does not cause relevant damage to energy, protein, and mineral metabolism.

Este trabalho teve como objetivo avaliar os efeitos da substituição parcial (750g/kg) do feno de Tifton por duas variedades de palma forrageira (Nopalea ou Opuntia) no perfil metabólico de cordeiros. Trinta e seis cordeiros Santa Inês, machos, não castrados (22,0 ± 2,9kg de peso corporal inicial), foram distribuídos em delineamento inteiramente ao acaso, com três tratamentos e 12 repetições. Os animais foram alimentados com dieta controle (feno de Tifton como volumoso exclusivo), dieta à base de palma forrageira Miúda ou dieta à base de palma forrageira Orelha de Elefante Mexicana (OEM). Amostras de sangue foram coletadas um dia antes (baseline) e 45 dias após a introdução das dietas testadas. A palma Miúda causou aumento (P=0,055) na atividade sérica da enzima gamaglutamiltransferase (53,66U/L) e no teor sanguíneo de glicose e frutosamina. A palma OEM causou menor teor (P=0,038) de colesterol sérico (41,33mg/dL). Independentemente da variedade, houve diminuição (P=0,001) do teor sérico de bilirrubina indireta, ureia e sódio, e aumento na concentração sérica de magnésio. A substituição parcial do feno de Tifton por palma Miúda ou por OEM na alimentação de cordeiros aumenta a atividade enzimática, o que indica alterações hepáticas e/ou renais, mas não causa danos relevantes nos metabolismos energético, proteico e mineral.

Cholangiocarcinoma in a bitch - multimodal diagnosis

Background: Hepatic tumors of primary origin account for 0.6% to 2.9% of cases in canine species, less common than hepatic metastases. The hepatic tumors are divided into hepatocellular tumors, neuroendocrine tumors, bile duct tumors or cholangiocarcinomas, and mesenchymal tumors. Cholangiocarcinomas, are classified according to their origin, being intrahepatic, extrahepatic, or gallbladder type. Cholangiocarcinomas are considered rare in dogs and cats with a ratio of 29% to 71% compared to hepatocellular carcinomas, accounting for 9% of the hepatic tumors. The present study aims to describe a case of cholangiocarcinoma in a bitch, focusing on the diagnostic approach. Case: A 10-year-old castrated bitch Poodle was attended presenting hypoglycemia and seizure crisis. The patient had previous exams of hemogram and serum biochemical profile, showing a discrete increase of the hepatic enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST), besides hypoglycemia. Previous ultrasound exam revealed the presence of a hepatic mass located between the right and square lobes, immeasurable, and significant splenomegaly. Abdominal palpation revealed the presence of immeasurable abdominal formation of undetermined origin. Abdominal computerized tomography (CT), glycemic curve, and insulin dosage were requested. Tomography exam showed an increase in hepatic volume with the presence of a heterogeneous formation in the right lateral lobe topography; increase in spleen dimensions and the presence of multiple nodules; and the presence of a nodule in the right lung, at the caudal thoracic region. The glycemic curve showed acute variations, and insulin dosage was between normal values. The animal was referred for surgery, as in abdominocentesis, it was observed the presence of hemorrhagic fluid, confirming active bleeding by ultrasonography. The owners chose for euthanasia. In the post-mortem evaluation the main lesion was confirmed of hepatic origin, with a massive, irregular, cavitary presentation, involving multiple hepatic lobes, and a single nodule was observed in the right caudal lobe of the right lung. Histopathological evaluation was considered inconclusive. Immunohistochemistry was performed and the association of the immunohistochemical profile with the morphological characteristics indicated diagnosis of cholangiocarcinoma. Discussion: The related symptomatology, in hepatic neoplasms, is generally considered non-specific, with reports of lethargy, vomiting, dyspnea, anorexia and weight loss, however, the dog in this study presented a unique manifestation of hypoglycemia and one episode of convulsive crisis resulting from it. The clinical manifestation observed was extremely unspecific making initial diagnosis difficult. The ultrasonographic examination was effective in evidencing the abdominal mass. In addition, abdominal CT was also performed, which confirmed the hepatic origin, detailing the macroscopic aspect. Biochemical analyses of ALT and AST showed a discrete increase. Biochemical changes may occur in dogs with hepatic neoplasms, although they are not specific. Functional pancreatic beta-cell tumors producing insulin are the most common cause of paraneoplastic hypoglycemia, although in the case the insulin dosage was within normal limits. In cases of nonislet cell tumor the mechanism is frequently associated with the production of insulin-like growth factor (IGF). In most cases the definitive diagnosis of cholangiocarcinoma can be obtained by histopathological examination, although in the present report the result obtained was inconclusive, requiring an immunohistochemical examination. Due to the aggressive and metastatic character of this neoplastic type, early detection becomes extremely important in order to maximize therapeutic chances, however, diagnosis may be difficult.

Casos clínicos de infertilidade em gatos / Clinical cases of infertility in cats

A criação comercial de gato doméstico tem aumentado assim como a realização de estudos para melhorar a eficiência reprodutiva é uma realidade. O interesse pela identificação das falhas reprodutivas tem crescido, entretanto, os casos de infertilidade nos machos são escassos na literatura disponível. O histórico de infertilidade de um gato deve ser investigado cuidadosamente, pois pode estar associado a mudanças no manejo ou doenças. O diagnóstico dessas 'falhas reprodutivas' geralmente é simples, se realizada uma boa anamnese, exames, físico e andrológico, minuciosos, assim como exames complementares, entre eles hemograma completo, perfil bioquímico e testes para doenças infecciosas como FIV, FELV e FIP.(AU)

Commercial breeding of domestic cats has increased, and studies to improve reproductive efficiency are a reality. Interest in identifying reproductive failures has increased, however, cases of infertility in men are scarce in the available literature. A cat's history of infertility should be investigated carefully as it may be associated with changes in management or illness. The diagnosis of these 'reproductive failures' is usually simple if a good anamnesis, thorough physical and andrological examinations are carried out, in addition to complementary tests, including complete blood count, biochemical profile, tests for infectious diseases such as FIV, FELV, FIP.(AU)

Efficacy of acidified phytase supplemented cottonseed meal based diets on growth performance and proximate composition of Labeo rohita fingerlings / Eficácia de dietas à base de algodão com fitase acidificada suplementada no desempenho do crescimento e na composição proximada de dedos de Labeo rohita

The growth of aquaculture sector is strongly dependent upon the continuous supply of inexpensive fish feed with balanced nutritional profile. However, fish meal (FM) is unable to satisfy this demand due to its scarce supply and high cost. In order to test the potential of cottonseed meal (CSM) as a fish meal replacer, a feeding trial of 12 weeks was conducted to check growth performance and proximate composition of Labeo rohita fingerlings. The protein ration of the test feed was satisfied by replacing FM with CSM at 0, 25, 50 and 75%. Sixteen test diets viz., TD1 (control), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 and TD16 were supplemented with citric acid (CA; 0 and 2.5%) and phytase (PHY; 0 and 750 FTU/kg) in a completely randomized design with 3×3 factorial arrangement. The highest weight gain (11.03g), weight gain% (249.21%), specific growth rate (1.39) and best feed conversion ratio (1.20) were recorded by fish fed with TD12. Furthermore, the same level increased the crude protein (59.26%) and fat (16.04%) being significantly different (p<0.05) than that of control. Conclusively, the addition of acidified phytase (CA; 2.5%, PHY; 750 FTU/kg) in TD12 (CSM=50%) led to the improved growth and proximate composition of L. rohita fingerlings.

O crescimento do setor de aquicultura é fortemente dependente do fornecimento contínuo de rações baratas para peixes com perfil nutricional equilibrado. Porém, a farinha de peixe (FM) não consegue atender a essa demanda devido à sua escassa oferta e alto custo. Com o objetivo de testar o potencial da farinha de semente de canola (MSC) como substituto da farinha de peixe, um ensaio alimentar de 12 semanas foi conduzido para verificar o desempenho de crescimento e a composição centesimal de alevinos de Labeo rohita. A ração de proteína da ração teste foi satisfeita substituindo FM por CSM em 0, 25, 50 e 75%. Dezesseis dietas de teste, viz., TD1 (controle), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 e TD16 foram suplementadas com ácido cítrico (CA; 0 e 2,5%) e fitase (PHY; 0 e 750 FTU / kg) em um delineamento inteiramente casualizado com arranjo fatorial 3 × 3. O maior ganho de peso (11,03g), % de ganho de peso (249,21%), taxa de crescimento específico (1,39) e melhor taxa de conversão alimentar (1,20) foram registrados por peixes alimentados com TD12. Além disso, o mesmo nível aumentou a proteína bruta (59,26%) e a gordura (16,04%), sendo significativamente diferente (p <0,05) do controle. Conclusivamente, a adição de fitase acidificada (CA; 2,5%, PHY; 750 FTU / kg) em TD12 (CSM = 50%) levou a um melhor crescimento e composição próxima de alevinos de L. rohita.

Ao final do experimento, os ratos foram sacrificados e amostras coletadas para estudos moleculares, bioquímica e histológicos. O estudo atual relatou que a suplementação de beldroegas frescas, especialmente a uma concentração de 75%, desempenha papel importante contra os efeitos prejudiciais da dieta rica em gordura em nível celular e orgânico, aumentando a expressão de CYP7A1 e Ldlr mRNA. Além disso, houve melhora nas funções hepáticas testadas, nos hormônios tireoidianos e no perfil lipídico. Beldroegas frescas desempenham papel potencial como agente hipolipemiante por meio da modulação de Ldlr e Cyp7A, o que apontará para o uso de beldroegas frescas contra os efeitos nocivos da obesidade.

The role of purslane in modulating diverse effects of high fat diet on biochemical, histological, and molecular parameters of rats' liver / O papel da beldroega na modulação de diversos efeitos da dieta rica em gordura nos parâmetros bioquímicos, histológicos e moleculares do fígado de ratos

Abstract Consuming a high-fat diet causes a harmful accumulation of fat in the liver, which may not reverse even after switching to a healthier diet. Different reports dealt with the role of purslane as an extract against high-fat diet; meanwhile, it was necessary to study the potential role of fresh purslane as a hypolipidemic agent. This study is supposed to investigate further the potential mechanism in the hypolipidemic effect of fresh purslane, by measuring cholesterol 7a-hydroxylase (CYP7A1) and low-density lipoprotein receptor (Ldlr). Rats were divided into two main groups: the first one is the normal control group (n=7 rats) and the second group (n=28 rats) received a high fat diet for 28 weeks to induce obesity. Then the high fat diet group was divided into equal four subgroups. As, the positive control group still fed on a high fat diet only. Meanwhile, the other three groups were received high-fat diet supplemented with a different percent of fresh purslane (25, 50 and 75%) respectively. At the end of the experiment, rats were sacrificed and samples were collected for molecular, biochemical, and histological studies. Current study reported that, supplementation of fresh purslane especially at a concentration of 75% play an important role against harmful effects of high-fat diet at both cellular and organ level, by increasing CYP7A1 as well as Ldlr mRNA expression. Also, there were an improvement on the tested liver functions, thyroid hormones, and lipid profile. Fresh purslane plays the potential role as a hypolipidemic agent via modulation of both Ldlr and Cyp7A, which will point to use fresh purslane against harmful effects of obesity.

Protective effects of Zizyphus oxyphyla on liver and kidney related serum biomarkers in (CCl4) intoxicate rabbits / Efeitos protetores de Zizyphus oxyphyla em biomarcadores de soro relacionados ao fígado e rim em (CCl4) intoxicam rabbtis

The study was aimed to evaluate the therapeutic effects of Zizyphus oxyphyla leaves methanolic (ZOX-LME), on serum liver, kidney and hematology along with other serum parameters in Carbon tetrachloride (CCl4) intoxicated rabbits. Experimental animals were divided into five groups, six rabbits in each. These were: group NC (normal control), group, TC (toxic control) and group ST i.e. silymarine administered group at dose rate (50) mg/kg body weight (BW). Group ET1 and group ET2 treated with (ZOX-LME) at dose 200 mg/kg BW and 400 mg/kg BW. CCl4 administration caused significant (P> 0.05) impairment in serum liver enzymes, blood factors and other serum indices. Treatment with (ZOX-LME) significantly (P<0.05) reduced and normalized the levels of serum alanine transaminase (ALT) aspartate transaminase (AST) and alkaline phosphatase (ALP) and hematological indices. Also significant (P< 0.05) reduction was observed in creatinine, urea, uric acid, blood urea nitrogen (BUN), and albumin and glucose concentrations. The altered levels of lipid profile and serum electrolytes (Ca, Mg, Cl, Na, K, and P) were significantly (P<0.05) change toward normal levels with (ZOX-LME) feeding. In addition (ZOX-LME) ingestion caused significant improvement in GSH, GST and CAT levels, while reducing the TBARS levels, exhibited antioxidant capacity. Also (ZOX-LME) showed increase inhibition against percent scavenging of 2, 2-diphenile-1-picrylehydrazyle (DPPH) free radical. Significant (P<0.05) normalizing effects were observed with high dose 400 mg/kg BW of (ZOX-LME and were equivalent to silymarine administered groups. The histological study of liver supported the hepatoprotective and renal curative activity of (ZOX-LME).

Os animais experimentais foram divididos em cinco grupos, seis coelhos em cada. Estes foram: grupo NC (controle normal), grupo TC (controle tóxico) e grupo ST, isto é, grupo administrado com silimarina na taxa de dose (50) mg / kg de peso corporal (PC). Grupo ET1 e grupo ET2 tratado com (ZOX-LME) na dose de 200 mg / kg de peso corporal e 400 mg / kg de peso corporal. A administração de CCl4 causou prejuízo significativo (P > 0,05) nas enzimas hepáticas séricas, fatores sanguíneos e outros índices séricos. O tratamento com (ZOX-LME) reduziu significativamente (P < 0,05) e normalizou os níveis de alanina transaminase (ALT), aspartato transaminase (AST) e fosfatase alcalina (ALP) e os índices hematológicos. Também foi observada redução significativa (P < 0,05) nas concentrações de creatinina, ureia, ácido úrico, nitrogênio ureico no sangue (BUN), albumina e glicose. Os níveis alterados de perfil lipídico e eletrólitos séricos (Ca, Mg, Cl, Na, K e P) foram significativamente (P < 0,05) mudando em direção aos níveis normais com a alimentação (ZOX-LME). Além disso, a ingestão de (ZOX-LME) causou melhora significativa nos níveis de GSH, GST e CAT, enquanto reduzia os níveis de TBARS, exibindo capacidade antioxidante. Também (ZOX-LME) mostrou inibição aumentada contra a eliminação percentual do radical livre 2, 2-difenila-1-picrilehidrazila (DPPH). Efeitos de normalização significativos (P < 0,05) foram observados com altas doses de 400 mg / kg de peso corporal de (ZOX-LME) e foram equivalentes aos grupos administrados com silimarina. O estudo histológico do fígado confirmou a atividade hepatoprotetora e curativa renal de (ZOX-LME).

Lesão traumática facial em cão - reconstrução cirúrgica com retalho de transposição rotacional / Facial traumatic injury in a dog - surgical reconstruction with rotational transposition flap

Background: Bite injuries are commonly found in small animal clinics, especially in male dogs, due to their habits of fighting and territorial disputes. In general, the lesions are treated with the use of compresses and bandages, however, it is extremely important to carefully evaluate the site, in order to carry out the appropriate treatment. In cases of tissue loss, an increasingly used practice is reconstructive surgery, which launches alternatives for treatment through flaps and skin grafts, promoting healing and satisfactory aesthetic repair. This report describes the case of a dog with a facial bite, treated with reconstructive surgery. Case: A 5-year-old male mixed-breed dog, with a body mass of 5 kg, was treated and submitted to a physical examination, due to the owner's complaint that he had been attacked by another dog, causing a bite on the face. On physical examination, the animal showed normal vital parameters, except for mild hyperthermia due to rectal temperature (39.5°C). On the face, it was possible to observe a lacerative lesion in the temporomandibular and masseteric regions, with loss of skin and muscle, in addition to having an aspect of infection and necrosis. To describe the hematological profile, a blood count was performed, showing no changes. In the biochemical tests, the present alteration was a slight increase in Alkaline Phosphatase (393.8 IU/L). Surgical treatment was indicated through facial reconstruction with a skin graft. After performing the antisepsis, the lesion was debrided, the edges were regularized and the injured tissue was curetted. For reconstruction of the defect, we used a flap obtained through a perpendicular incision at the base of the ear, in a caudal direction, and this flap was pulled and transposed over the wound. Flap synthesis was performed with 3-0 nylon thread. After surgery, a compressive bandage was performed, which was removed after 24 h. It was indicated to avoid exertion in the area and to return in 10 days for the evaluation of the surgery and removal of the stitches. Discussion: Traumatic injuries in animals are being increasingly reported, with male and non-neutered dogs being the most prevalent patients. This report is in line with other studies, with the patient's profile being a male dog, with an average age, in line with the literature. In general, in certain types of wounds, the affected animals can develop sepsis and even progress to death, however, in this case the patient did not show changes in vital parameters and in hematological tests. Reconstructive surgeries are performed with the aim of correcting skin defects and knowledge of the available techniques is important. It is also necessary to carry out a good planning, in order to avoid complications in the trans and postoperative period. In the present case, we chose to use a flap obtained through an incision perpendicular to the base of the ear, transposing it over the wound, in addition to relieving tissue tension through skin divulsion, increasing its elastic potential. The use of bandages is considered extremely important for the success of the surgical procedure, as it provides an efficient barrier against infections, trauma and adhesions. However, we emphasize the need to use ointments, gauzes and bandages concomitantly, in order to have the desired success in the postoperative period. In addition to proper surgical techniques, pain management and infection control are important for patient recovery. It is important to use non-steroidal anti-inflammatory drugs and opioids to obtain analgesia, in addition to antibiotic therapy before and after surgery. The reported case demonstrated that lesions in dogs with skin loss can be reconstructed using skin flaps, with an excellent recovery and good prognosis, as was the case with the patient in this report.

Extruded urea could replace true protein source in supplements for lambs finished in tropical pastures / A ureia extrusada pode substituir a fonte de proteína verdadeira em suplementos para cordeiros terminados em pastagens tropicais

The aim of this study was to evaluate the effects of replacing 50% of the true protein from soybean meal with extruded urea on the performance and carcass characteristics of lambs finished on pasture. Twenty lambs with initial weight of 29.9±6.2kg and 5 months of age, distributed in two treatments in blocks at random, were kept in pastures of Urochloa spp. Supplemented with 2% of body weight (BW). The treatments consisted of supplements containing soybean meal as the only true protein source (control), or extruded urea replacing 50% of soybean meal (NPN treatment). There was no effect of treatment on total supplement intake. There were differences in average daily gain (242.1 vs. 264.6g/day), slaughter weight (41.9 vs. 45.0kg) and carcass weight (18.9 vs. 20.1kg). There was no effect of the treatment on the final body condition score, hot carcass yield, carcass length, breast depth, subcutaneous fat thickness or rib eye area. The group of animals that received extruded urea showed superior carcass finishing characteristics (99.0% vs. 66.0%), maturity (22.0% vs. 0.0%), marbling (55.0% vs. 33.0%), meat texture (44.0% vs. 33.0%) and fat (66.0% vs. 22.0%). There were no significant effects on tenderness (7.5kg/f) or flesh color (L* = 33.2; a* = 16.2; b* = 8.3). There were no significant changes in the biochemical profile of the animals' blood during the experiment for both treatments. The replacement of 50% of protein from soybean meal by the extruded urea as NPN source in the supplement for lambs finished in Urochloa spp pastures provides better animal performance and qualitative characteristics of meat, without altering quantitative carcass characteristics.

Objetivou-se avaliar os efeitos da substituição de 50% da proteína verdadeira do farelo de soja por ureia extrusada sobre o desempenho e as características de carcaça de cordeiros terminados em pasto. Vinte cordeiros de 29,9+6,2kg de peso inicial e com cinco meses de idade, distribuídos em dois tratamentos em blocos ao acaso, foram mantidos em pastagens de Urochloa spp. suplementado com 2% do peso vivo (PV). Os tratamentos consistiram em suplementos contendo farelo de soja como única fonte de proteína verdadeira (controle), ou ureia extrusada em substituição a 50% do farelo de soja (tratamento NPN). Não houve efeito do tratamento na ingestão total de suplemento. Houve diferenças no ganho médio diário (242,1 vs. 264,6 g/dia), no peso ao abate (41,9 vs. 45,0kg) e no peso da carcaça (18,9 vs. 20,1kg). Não houve efeito do tratamento sobre escore de condição corporal final, rendimento de carcaça quente, comprimento de carcaça, profundidade do peito, espessura de gordura subcutânea ou área de olho de lombo. O grupo de animais que recebeu ureia extrusada apresentou características superiores de acabamento de carcaça (99,0% vs. 66,0%), maturidade (22,0% vs. 0,0%), marmoreio (55,0% vs. 33,0%), textura da carne (44,0% vs. 33,0%) e gordura (66,0% vs. 22,0%). Não houve efeitos significativos na maciez (7,5 kg/f) nem na cor da carne (L*= 33,2; a*= 16,2; b * = 8,3). Não houve mudanças significativas no perfil bioquímico do sangue dos animais durante o experimento para ambos os tratamentos. A substituição de 50% da proteína do farelo de soja pela ureia extrusada como fonte de NPN no suplemento para cordeiros terminados em pastagem de Urochloa spp. proporciona melhor desempenho animal e características qualitativas da carne, sem alterar as características quantitativas da carcaça.

Hérnia diafragmática peritôniopericárdica congênita em uma gata / Congenital peritoniopericardial diaphragmatic hernia in a female kitten

Background: Peritoneopericardial diaphragmatic hernia is a rare pathogenesis of congenital origin, which occurs due to a failure in the communication between the diaphragm and the pericardium during embryogenesis. Symptoms may be non-existent or non-specific, depending on the herniated organ involved and, in most cases, the diagnosis is incidental. Regarding the most indicated treatment, there are still divergences in the literature concerning the indication of conservative or surgical treatment. This study reports the case of a feline peritoneopericardial hernia, for which surgical correction was the treatment of choice. Case: A 3-month-old female kitten, no defined racial pattern, was referred to the Veterinary Hospital of the Federal Rural University of Pernambuco for treatment of a peritoneopericardial diaphragmatic hernia. This condition was diagnosed through radiographic examination after the patient having been submitted to pediatric castration and presented anesthetic complications in the transsurgery. Blood count, biochemical profile and Doppler echocardiogram were performed, which showed no significant changes. To obtain a better study and surgical planning, computed tomography was performed to observe the heart located cranially in the pericardial cavity. Caudally to the heart, hepatic parenchyma located in the pericardial cavity was observed; and hepatic vessels presenting slightly enlarged dimensions. These tomographic findings suggested peritoneopericardial diaphragmatic hernia; being the liver present in the pericardial cavity and signs of congestion in the hepatic parenchyma. Due to the likelihood of future worsening of the hernia, surgical correction was performed, with an abdominal midline incision in the preumbilical region to reposition the liver to its normal anatomy, followed by diaphragm reconstitution through a herniorrhaphy. After the surgical procedure, the patient was referred for observation in internment and, after 15 days, the skin sutures were removed. Complete correction of the hernial defect was observed on radiography performed 30 days after the surgical procedure. However, the examination showed the presence of deviation/ deformity in the topography of the sternum and costal cartilages, with slight cardiac displacement to the right hemithorax, suggesting the presence of pectus excavatum. Discussion: Peritoneopericardial diaphragmatic hernia is considered rare and, despite being one of the most common causes of congenital pericardial anomaly in felines, it has a low prevalence ranging from 0.06% to 1.45%. They are usually diagnosed from two years of age, with prevalence for older animals. However, due to having presented anesthetic changes, the patient of this case report could be diagnosed early. Among the most common organs that migrate to the thoracic cavity, the liver is the most commonly observed, which is also the hernia content of the present report. Peritoneopericardial hernia is often diagnosed through radiography and ultrasound, and these imaging tests proved to be sufficient for the diagnosis in this report. However, computed tomography was important for providing a better study of case and for the adoption of median celiotomy as a treatment. Associations with other malformations are described in the literature, with pectus excavatum being the most common and also observed in this report. Peritoneopericardial diaphragmatic hernia is a rare anomaly, rarely reported in the literature and with divergences regarding its treatment. The adoption of early surgical treatment performed in this report showed satisfactory evolution and the possibility of a favorable prognosis.
