RESUMEN
BACKGROUND: Globally, hypertension represents a major public health problem. The association between 25-hydroxyvitamin D (25[OH]D) levels and hypertension remains unclear. The current study aimed to investigate the association between serum 25(OH)D levels and hypertension among adults in Sudan. METHODS: A community-based cross-sectional study was conducted among adults in North Sudan. Sociodemographic and clinical data were collected using a questionnaire and face-to-face interviews. Serum 25(OH)D was measured using an enzyme-linked immunosorbent assay. Multivariate logistic regression and multiple linear regression analyses were performed. RESULTS: Of the total of 391 participants, 202 (51.7%) were females. The median (interquartile range [IQR]) of participants' ages was 45(32-55) years. Of the total, 219(56.0%) had hypertension. The median (IQR) of serum25(OH)D was 13.3(9.9-19.7) ng/mL, and 295 (75.4%) participants had vitamin D deficiency (< 20 ng/mL). In multivariable logistic regression, the adjusted odds ratio (AOR) for age = 1.05, 95% confidence interval (CI)1.03â1.061, the AOR for being female = 2.02, 95% CI, 1.12â3.66, and body mass index was AOR = 1.09, 95% CI, 1.05â1.14, all of which were significantly associated with hypertension. However, serum 25(OH)D levels were not associated with hypertension (AOR = 1.01, 95% CI 0.99â1.05, P = 0.317). In multiple linear regression, while systolic blood pressure was negatively associated with 25(OH)D (coefficient = - 0.28, P = 0.017), there was no significant association between serum 25(OH)D level and diastolic blood pressure (coefficient = - 0.10, P = 0.272) or mean blood pressure (coefficient =-0.03, P = 0.686). CONCLUSION: The current study revealed a negative association between vitamin D and systolic blood pressure. The mechanism of such an association needs further study.

BACKGROUND: Diabetes mellitus (DM) is a global health threat and burden that is associated with many chronic complications. Erectile dysfunction (ED) among patients with DM is one of these complications. There is no published data on ED in Sudan; hence, we conducted this study to evaluate the prevalence of ED and the associated factors in patients with type 2 diabetes mellitus (T2DM) in eastern Sudan. METHODS: We performed a cross-sectional study. Data on blood glucose level, cholesterol level, anthropometric and demographic characteristics, results of the International Index of Erectile Function (IIEF-5) questionnaire, and clinical history were obtained. RESULTS: A total of 334 men with T2DM with a median (interquartile range [IQR]) age of 55.0 (±10.0) years were enrolled in the study. The median (IQR) of the duration of DM was 7.0 (±8) years, and 260 (77.8%) had uncontrolled T2DM. The median (IQR) body mass index was 24.5 (±4.9) kg/m2. Of the participants, 81 (24.3%) had severe ED, 52 (15.6%) had moderate ED, 75 (22.5%) had mild to moderate ED, and 63 (13.9%) had mild ED. Of the 334 men, 271 (81.1%) had ED. Logistic regression analysis showed that age (adjusted Odds Ratio [AOR] = 1.07, 95% confidence interval [CI] = 1.01-1.14), duration of DM (AOR = 1.26, 95% CI = 1.06-1.51), and cholesterol levels (AOR = 3.53, 95% CI = 1.75-7.11) were positively associated with ED. Moreover, poor glycaemic control (AOR = 3.38, 95% CI = 1.70-6.71, P < 0.001) was significantly associated with ED. CONCLUSION: There is a high prevalence of ED among patients with T2DM in eastern Sudan. Age, duration of DM, and cholesterol were positively associated with ED.

BACKGROUND: Glycosylated haemoglobin (HbA1c) is considered reliable for diagnosing and monitoring diabetes mellitus (DM). It also indicates cardiovascular complications related to DM. However, only a few studies have been conducted on this topic. METHODS: We conducted a cross-sectional study to investigate the association between newly diagnosed hypertension and HbA1c among non-diabetic Sudanese adults. The sociodemographic characteristics of the participants in the sample were gathered using a questionnaire, and HbA1c was measured using an Ichroma machine. RESULTS: Three hundred and eighty-four healthy participants were enrolled in this study. The median (interquartile range [IQR]) age was 56.0 (14.0) years, and 72.1% of the participants were female. The median (IQR) body mass index (BMI) was 31.2 (8.7) kg/m2. One hundred and fifteen (29.9%) participants presented newly diagnosed hypertension. The results of the multivariate analysis showed that age (adjusted odd ratio [AOR] = 1.03; 95% confidence interval [CI] = 1.01â1.05); BMI (AOR = 1.09; 95% CI = 1.05â1.14); HbA1c levels (AOR = 2.18; 95% CI = 1.29â3.67) was positively associated with newly diagnosed hypertension. For an HbA1c level of 5.0% or more, the sensitivity and specificity of newly diagnosed hypertension were 91.3% and 28.2%, respectively (area under the curve = 0.61; 95% CI = 0.55-0.67; P Ë 0.001). Participants who presented HbA1c levels of 5.0% or more were found to be at higher risk for newly diagnosed hypertension (AOR = 2.53; 95% CI = 1.14â5.61). CONCLUSION: The results of this study indicated a high prevalence of newly diagnosed hypertension, and HbA1c levels were positively associated with newly diagnosed hypertension.

BACKGROUND: Hypertension and diabetes mellitus (DM), are highly prevalent worldwide health non-communicable diseases, and are associated with chronic complications. The co-existence of both conditions accelerates the related complications and increases morbidities and mortalities. A cross-sectional study was conducted in Nahr an Nil State (River Nile State) in Sudan between May and August 2018 to identify the prevalence of hypertension and risk factors among patients with DM in that region. RESULTS: The median (interquartile) age of the 1,973 enrolled patients was 58.0 (50.0â65.0) years, and 818 (45.6%) were males. The median (interquartile) duration of diabetes was 5.0 (3.0â9.0) years. Of the 1,973 enrolled participants, 21.7%, 1.3%, 37.1%, and 39.9% were normal weight, underweight, overweight, and obese, respectively. Of 1,973 854 (47.6%) patients also had hypertension. Logistic regression analyses showed that elderly patients (adjusted odds ratio [AOR] = 1.03, 95%; confidence interval [CI] = 1.02â1.04), males (AOR = 2.96, 95%; CI = 2.15â4.07), employed patients (AOR = 1.92, 95%; CI = 1.38â2.70), obese patients (AOR = 1.59, 95%; CI = 1.21â2.08), and patients with diabetic foot (DF) (AOR = 2.45, 95%; CI = 1.72â3.47) were at higher risk for hypertension. Conversely, patients with Type 2 DM (T2DM) (AOR = 0.63, 95%; CI = 0.50â0.80) were at lower risk for hypertension. There was no significant association between overweight, uncontrolled DM, and hypertension. CONCLUSION: This study showed a high prevalence of hypertension among patients with DM. Notably, older age, male gender, employment, duration of DM, DF, underweight, and obesity were significant predictors of hypertension among patients with DM.

OBJECTIVE: The aim of this study was to determine the prevalence and associated factors for diabetic foot (DF) amongst patients with diabetes Mellites (DM) in Nahr an Nil State (River Nile State), Sudan. METHODS: We conducted a cross-sectional study between May and August 2018. DM patients were examined for DF, and clinical data were collected through a questionnaire. RESULTS: A total of 2048 DM patients were enrolled in the study. Their median (interquartile range) age was 58 (15) years. Over half (54.2%) of the patients were female. The median (interquartile range) of the duration of diabetes was 5 (6) years. In this sample, 70.1% of the patients had type 2 DM and 47.6% had hypertension as well. Of all enrolled patients, 21.2% had normal weight, 1.2% were underweight, 37.2% were overweight and 40.4% were obese. Two hundred and sixty (12.7%) patients had DF. Multivariate regression analyses showed that age [adjusted odds ratio (AOR) = 1.21; 95% confidence interval (CI): 1.18-1.24] and duration of DM (AOR = 1.09; 95% CI: 1.05-1.14) were positively associated with DF. Moreover, type 2 DM (AOR = 1.77; 95% CI: 1.17-2.68), family history of DM (AOR = 1.5; 95% CI: 1.07-2.09), hypertension (AOR = 2.93; 95% CI: 2.07-4.16) and obesity (AOR = 2.86; 95% CI: 1.70-4.81) were associated with DF. There was no significant association between DF and gender or overweight status. CONCLUSION: This study found a high prevalence of DF. Older age, type 2 DM, duration of DM, family history of DM and hypertension are associated with DF.

Introduction: Diabetes mellitus (DM) is one of the world's major public health problems. There are few published data on 25-hydroxyvitamin D (25[OH]D) concentrations and DM, and these studies showed different results. Objectives: The current study aimed to compare 25[OH]D concentrations between patients with type 2 DM (T2DM) and healthy controls in eastern Sudan. Methods: A case-control study of two groups matched for age and gender (88 in each group) was conducted in eastern Sudan from March to May 2022. The cases were patients with T2DM, and the controls were healthy participants. Sociodemographic data were collected, and serum 25(OH)D levels were assessed. A univariate analysis was performed. Results: Of the total 176, 82 (47%) were males, and 94 (53%) were females; the median (interquartile range [IQR]) of age, body mass index (BMI), and 25(OH)D concentration were 55 (50-61) years, 27 (23-31) kg/m2, and 13 (10-19) ng/mL, respectively. Of the 176, 137 (78%) were vitamin D deficiency cases. Compared with the controls, age, gender, educational level, marital status, or BMI were not different in the circumstances. Moreover, the median (IQR) for serum 25(OH)D concentrations showed no difference between patients with T2DM and the healthy controls (12 [10-18] ng/mL vs. 13 [10-20] ng/mL). The prevalence of vitamin D deficiency (25(OH)D level < 20 ng/mL) was not different between patients with T2DM and the healthy controls (66/88 [75%] vs. 71/88 [81%]). There was no association in the serum 25(OH)D levels between diabetic and nondiabetic participants (OR = 1.01, 95% CI 0.97-1.06) or in vitamin D deficiency between diabetic and nondiabetic participants (OR = 0.72, 95% CI 0.35-1.47). Conclusion: There was no significant difference in 25(OH)D levels between diabetic and nondiabetic participants in this study. Further studies investigating the mechanisms of association between 25(OH)D levels and DM are needed.
RESUMEN
INTRODUCTION: Online learning involves the delivery of educational instructions regarding a subject using the internet. Pathology is an experimental subject that requires students to learn about disease development via unpleasant photos and slides. This study aims to determine the rewards and struggles of online pathology learning during the coronavirus disease 2019 (COVID-19) pandemic at the Al-Qunfudah Medical College, Kingdom of Saudi Arabia. METHODS: Using an online questionnaire comprising three sections of 23 questions (12 questions about the positive perception of online teaching and 11 about the negative perception), we surveyed second and third-year pathology students about their perception of online education. The positive and negative perceptions of the students were compared using the chi-square test (p < 0.05). RESULTS: About 77% of the students (n = 85/110) responded to the survey. Female students (n = 43, 50.6%) had a significantly higher positive perception of online learning (p < 0.001); male students (n = 42, 49.4%) had a high negative perception of online teaching (p < 0.035). Nearly 70% of the students agreed that the Blackboard platform (Anthology Inc., Boca Raton, FL) made learning easy. About two-thirds of students agreed that the pre-lecture video produced by the teachers, when shared before the lesson, made the pathology lectures easy. CONCLUSION: Female students were more favorable toward online pathology learning. Extensive training provided to teachers can significantly increase the support given to students during online teaching.
RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Origanum majorana L. is a member of the Lamiaceae family and is commonly used in Egyptian cuisine as a seasoning and flavor enhancer. It is also recognized as a well-known traditional medicine in Egypt and is widely used for treating abdominal colic due to its antispasmodic properties. However, the protective effects of Origanum majorana L. against ulcerative colitis and its underlying mechanisms remain unclear. AIM OF THE STUDY: This study aimed to identify the biologically active components present in methanol extracts of Origanum majorana L. using gas chromatography/mass spectrometry (GC/MS). Additionally, it aimed to investigate the therapeutic effects of these extracts on acetic acid-induced ulcerative colitis and elucidate the potential mechanisms involved. MATERIALS AND METHODS: We conducted a GC-MS analysis of the methanolic extract obtained from Origanum majorana L. Thirty-two male rats were included in the study and divided into four experimental groups, with eight rats in each group: sham, UC, UC + O. majorana, and UC sulfasalazine. After euthanizing the rats, colon tissue samples were collected for gross and microscopic examinations, assessment of oxidative stress, and molecular evaluation. GC-MS analysis identified 15 components in the extracts. Pretreatment with O. majorana L. extract and sulfasalazine significantly improved the disease activity index (DAI) and resulted in notable improvements in macroscopic and microscopic colon findings. Additionally, both treatments demonstrated preventive effects against colonic oxidative damage by reducing the levels of malondialdehyde (MDA) and increasing the levels of the antioxidant systems superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), which operate through the Nrf2/HO-1 signaling pathway. Moreover, these treatments downregulated the colonic inflammatory cascade by inhibiting NFκB, TNFα, IL-1ß, IL6, IL23, IL17, COX-2, and iNOS, subsequently leading to downregulation of the JAK2/STAT3 signaling pathway and a decrease in the Th17 cell response. Furthermore, a reduction in the number of apoptotic epithelial cells that expressed caspase-3 was observed. CONCLUSION: pretreatment with O. majorana L. extract significantly ameliorated acetic acid-induced ulcerative colitis. This effect could be attributed to the protective, antioxidant, anti-inflammatory, and anti-apoptotic properties of the extract.

Cyclosporine (CsA) is considered one of the main components of treatment protocols for organ transplantation owing to its immunosuppressive effect. However, its use is very restricted due to its nephrotoxic effect. ZW is an alkaline fluid rich in various trace elements and has a great ability to stimulate antioxidant processes. This study aimed to investigate the possible mitigating effect of ZW on CsA-induced nephrotoxicity and its underlying mechanisms. Forty rats were allocated into four groups (n = 10): a control group, ZW group, cyclosporine A group (injected subcutaneously (SC) with CsA (20 mg/kg/day)), and cyclosporine A+ Zamzam water group (administered CsA (SC) and ZW as their only drinking water (100 mL/cage/day) for 21 days). Exposure to CsA significantly (p < 0.001) increased the serum creatinine level, lipid peroxidation marker level (malondialdehyde; MDA), and the expression of apoptotic markers procaspase-8, caspase-8, caspase- 9, calpain, cytochrome c, caspas-3, P62, and mTOR in renal tissues. Meanwhile, it markedly decreased (p< 0.001) the autophagic markers (AMPK, ULK-I, ATag5, LC3, and Beclin-1), antiapoptotic Bcl-2, and antioxidant enzymes. Moreover, the administration of CsA caused histological alterations in renal tissues. ZW significantly (p < 0.001) reversed all the changes caused by CsA and conclusively achieved a positive outcome in restraining CsA-induced nephrotoxicity, as indicated by the restoration of the histological architecture, improvement of renal function, inhibition of apoptosis, and enhancement of autophagy via the AMPK/mTOR pathway.
RESUMEN
Background: Hyperglycemia usually impairs wound healing by dysregulating the inflammatory response and angiogenesis. This study aimed to examine the synergistic effect of dapagliflozin and Zamzam water (ZW) on the healing of diabetic wounds and to explore their anti-inflammatory and proangiogenic effects.Materials and methods: A full-thickness excisional wound was made on the backs of all groups after two weeks of diabetes induction. Forty rats were divided into five groups, with eight rats per group; Group 1: Control non-diabetic rats; Group II: Untreated diabetic rats; Group III: Diabetic rats drinking ZW; Group IV: Diabetic rats receiving an oral dose of 1 mg/kg dapagliflozin; and Group V: Received both dapagliflozin and ZW. The healing of diabetic wounds was assessed by measuring wound closure, oxidative stress markers, immunohistochemical staining of NF-ßB, VEGF, CD34, CD45, Ki-67, and eNOS, gene expression of MMP-9, TGF-ß1, EGF-b1, FGF, and Col1A1, protein levels of TNFα, IL-1ß, IL6, Ang II, and HIF-1α by ELISA assay, and histological examination with H & E and Masson's trichrome. Combined treatment with dapagliflozin and ZW significantly (p < 0.05) enhanced the wound closure and antioxidant enzyme level, with apparent histological improvement, and shortened the inflammatory stage of the diabetic wound by decreasing the level of inflammatory markers NF-κB, TNF-α, IL-1ß, IL6, and CD45. Therefore, it improved angiogenesis markers VEGF, CD34, eNOS, EGF-ß1, FGF, Ang II, and HIF-1α, increasing Ki-67 cellular proliferation. Moreover, it enhanced the remodeling stage by increasing MMP-2, TGF-ß1, and Col1A1 levels compared to diabetic rats.

Introduction: Recent studies have reported a strong relationship between diabetes and anxiety- and depression-like behaviors; however, there is a lack of information on the underlying pathophysiology. Alkaline Zamzam water (ZW), which is rich in several trace elements, has neuroprotective properties. This study aimed to investigate the anxiolytic and antidepressant effects of ZW against diabetes-induced behavioral changes and shed light on the possible underlying mechanisms. Methods: Forty-eight rats were divided into four experimental groups (n = 12): group I (control group), group II (Zamzam water group), group III (diabetic group), and group IV (diabetic + Zamzam water group). Diabetes was induced by an intraperitoneal injection of 60 mg/kg streptozotocin (STZ). At the end of the experiment, the forced swimming test (FST) was used to assess depression-like effects. The elevated plus maze test (EPMT) and open field test (OFT) were performed to evaluate anxiety-like behavior. Blood levels of the hypothalamic-pituitary-adrenal (HPA) axis were measured, and prefrontal cortex and hippocampal tissue samples were removed for histological, immunohistochemical, ELISA, and Q-PCR analyses. Results: ZW significantly decreased the immobility time in the FST, indicating an antidepressant effect (p < 0.001). Additionally, ZW significantly improved the OFT and open field entry (OFE) percentages in the EPMT, increasing center crossing and decreasing grooming and fecal boli in the OFT. This indicated an anxiolytic-like effect in diabetic rats with histological improvement. Interestingly, ZW significantly increased prefrontal cortical and hippocampal levels of antioxidant enzymes and the Nrf2/HO-1 pathway. It also modulated the HPA axis by increasing cortisol and corticotropin-releasing hormone (CRH) levels, with a decrease in ACTH and an increase in monoamine neurotransmitters. Furthermore, diabetic rats that received ZW showed a decrease in the inflammatory markers TNF-α and GFAP by immunohistochemistry and in the mRNA levels of NFκB, IL-1ß, and IL6. In addition, ZW downregulated the expression of the BDNF/ERK2/CREP pathway. Conclusion: Our results suggested a neuroprotective effect of ZW against diabetes-induced anxiety- and depression-like behaviors and explored the underlying mechanisms. These findings suggest a promising therapeutic strategy for patients with diabetes who experience anxiety and depression.
RESUMEN
BACKGROUND: Lactating mothers are susceptible to anaemia. Little published data are available on lactational anaemia in Africa, including Sudan. This study was conducted to assess the prevalence of and associated factors for anaemia among lactating mothers in eastern Sudan. METHODS: A cross-sectional study was conducted and sociodemographic and clinical characteristics were gathered through a questionnaire. RESULTS: A total of 650 lactating mothers were included in the analysis. Their median age and parity were 28.0 y (interquartile range [IQR] 23.7â32.0) and 3.0 (IQR 2.0â4.0), respectively. Haemoglobin (Hb) levels ranged from 7.0 to 15.0 g/dL (median 11.2 [IQR 10.4â12.0]). Of the 650 lactating mothers, 442 (68.0%) had anaemia (Hb <12.0 g/dL). In multivariate analysis, lactating mothers with education less than the secondary level (adjusted odds ratio [AOR] 1.58 [95% confidence interval {CI} 1.05 to 2.37]) and lactating mothers who underwent caesarean delivery (AOR 1.74 [95% CI 1.17 to 2.58]) had a higher probability of being anaemic. Employment was associated to a lower frequency of anaemia (AOR 0.39 [95% CI 0.20 to 0.79]). CONCLUSIONS: This study showed a high prevalence of anaemia among lactating mothers. Public health intervention activities designed towards education would be helpful to reduce anaemia.

Background: Obstetric haemorrhage is a leading cause of maternal mortality and morbidity worldwide. Caesarean delivery (CD) is associated with significant blood loss, which may require blood transfusions. This study aimed to determine the prevalence and associated factors for post-CD transfusion. Methods: A cross-sectional study was conducted in Gadarif maternity hospital, eastern Sudan, from March to September 2020. Sociodemographic, obstetric and clinical data, including pre- and postoperative haemoglobin levels, were collected. A multivariate logistic regression analysis was performed. Results: A total of 539 women were enrolled in the study; the median (interquartile range) age of these women was 28.0 (8.0) years. The overall post-CD transfusion rate was 8.2%. Emergency CD (adjusted odds ratio [AOR]=2.57, 95% confidence interval [CI]=1.25â5.28) and antepartum haemorrhage (AOR=44.70, 95% CI=11.18â178.76) were associated with increased risk of post-CD blood transfusion. Preoperative haemoglobin (AOR=0.48, 95% CI=0.36â0.64) and rural residence (AOR=0.45, 95% CI=0.22â0.93) were associated with reduced risk for post-CD blood transfusion. Conclusion: The overall prevalence of post-CD transfusion in this part of Sudan is 8.2%. Women with emergency CD, low preoperative haemoglobin levels and antepartum haemorrhage were at higher risk for post-CD transfusion. Risk identification and correction of antenatal anaemia can reduce the hazard of blood transfusion among CD women.
RESUMEN
Gentamicin is considered one of the most typical causes of testicular damage. Oxidative stress is a significant contributor to testicular tissue damage. Zamzam water (alkaline in nature) has an antioxidant effect. The purpose of this study was to assess the potential palliative effect of Zamzam water against gentamicin-induced testicular damage. Thirty Rats were separated into three groups, each with ten rats, as follows: The Control received only normal saline. The gentamicin group received 100 mg/kg/day of gentamicin intraperitoneally for six days from day 15 to the end of the experiment. The gentamicin +Zamzam Water group received a dose of gentamicin 100 mg/kg/day intraperitoneally with Zamzam water as their sole source of drinking from day one to day 21. Hormonal assay in serum, histological, immunohistochemical, and ultrastructural examination of testicular tissue with a molecular study were obtained. Pretreatment with Zamzam water significantly p < 0.001 increased serum levels of testosterone, FSH, and LH, as well as the percentage of sperm motility and progressive motility. It also upregulated SOD, CAT, GPx enzymatic activity, gene expression of Nrf2/HO-1, and immunoexpression of PCNA. While the percentage of dead sperm and abnormal sperm, immunoexpression of NFκB, Caspase 3, inflammatory cytokines TNFα, IL-1ß, IL-6, and MDA levels significantly (p < 0.001) declined with histological improvement. It was concluded that Zamzam water as alkaline water possesses antioxidant, anti-inflammatory, and antiapoptotic effects against gentamicin-induced testicular toxicity in vivo.
RESUMEN
SUMMARY: One of the reasons for acute kidney damage is renal ischemia. Nevertheless, there are limited protective and therapeutic approaches for this problem. Diacerein is an anti-inflammatory drug characterized by numerous biological activities. We aimed to determine the ameliorative impact of diacerein on renal ischemia/reperfusion injury (I/R) condition, exploring the underlying mechanisms. Twenty-four male rats were allotted into four groups (n= 6): sham group; Diacerein (DIA) group; I/R group, in which a non-crushing clamp occluded the left renal pedicle for 45 min, and the right kidney was nephrectomized for 5 min before the reperfusion process; I/R + diacerein group, injected intraperitoneally with 50 mg diacerein/kg i.m 30 minutes prior to I/R operation. Ischemia/ reperfusion was found to affect renal function and induce histopathological alterations. The flow cytometry analysis demonstrated an elevated expression of innate and mature dendritic cells in I/R renal tissues. Moreover, upregulation in the expression of the inflammatory genes (TLR4, Myd88, and NLRP3), and overexpression of the pro-inflammatory cytokines (IL-1β), apoptotic (caspase-3) and pyroptotic (caspase-1) markers were observed in I/R-experienced animals. The aforementioned deteriorations were mitigated by pre-I/R diacerein treatment. Diacerein alleviated I/R-induced inflammation and apoptosis. Thus, it could be a promising protective agent against I/R.
La isquemia renal es una de los motivos del daño renal agudo. Sin embargo, los enfoques protectores y terapéuticos para este problema son limitados. La diacereína es un fármaco antiinflamatorio caracterizado por numerosas actividades biológicas. Nuestro objetivo fue determinar el impacto de mejora de la diacereína en la condición de lesión por isquemia/ reperfusión renal (I/R), explorando los mecanismos subyacentes. Veinticuatro ratas macho se distribuyeron en cuatro grupos (n= 6): grupo simulado; grupo de diacereína (DIA); grupo I/R, en el que una pinza no aplastante ocluyó el pedículo renal izquierdo durante 45 min, y el riñón derecho fue nefrectomizado durante 5 min antes del proceso de reperfusión; Grupo I/R + diacereína, inyectado por vía intraperitoneal con 50 mg de diacereína/kg i.m. 30 min antes de la operación I/R. Se encontró que la isquemia/ reperfusión afecta la función renal e induce alteraciones histopatológicas. El análisis de citometría de flujo demostró una expresión elevada de células dendríticas innatas y maduras en tejidos renales I/R. Además, se observó una regulación positiva en la expresión de los genes inflamatorios (TLR4, Myd88 y NLRP3) y una sobreexpresión de las citoquinas proinflamatorias (IL-1β), marcadores apoptóticos (caspasa-3) y piroptóticos (caspasa-1) en animales con experiencia en I/R. Los deterioros antes mencionados fueron mitigados por el tratamiento previo a la diacereína I/R. La diacereína alivió la inflamación y la apoptosis inducidas por I/R. Por lo tanto, podría ser un agente protector prometedor contra I/R.

To evaluate the accuracy of different single plasma sample methods (SPSM) 99m Tc-DTPA clearances and to test whether the SPSM can replace the dual plasma samples method (DPSM) in the measurement of glomerular filtration rate (GFR), we studied 430 subjects counting renal patients and donors (240 male, 190 female; mean age 43.40 ± 16.30 years). All the subjects underwent dynamic renal scintigraphy after injection of 99m Tc-DTPA; the GFR was calculated by seven SPSMs in addition to DPSM as a reference. Each of the SPSM clearance was compared with the DPSM measurement. There was a high correlation of all the SPSMs and the DPSM. The limits of agreement (95%) were found between the DPSM and all the SPSMs. Overall, the best method among the SPSMs, which is closest to the DPSM, is Fleming's single method as it has a statistically significant low mean difference (bias), low standard error, close mean ± SD to the reference method, good limits of agreement and high correlation co-efficient. This study concludes that, among the SPSMs, Fleming can reflect GFR more accurately than other methods, particularly when the expected serum creatinine is normal.
