| 5 | Agmatine ameliorates diabetes type 2-induced nephropathy in rats显示文摘Objective:To assess the nephroprotective potential of agmatine in a rat model of streptozotocin-induced diabetic nephropathy.Methods:A single dose of streptozotocin(40 mg/kg)coupled with a fructose diet induced diabetes in Wistar rats.Agmatine(40 and 80 mg/kg)was administered to rats for 12 weeks.The body weight and fasting blood glucose were measured weekly.Insulin level,urine output,total protein,albumin,blood urea nitrogen,creatinine,and cystatin-C were also determined at the end of the experiment.Furthermore,superoxide dismutase,glutathione,interleukin-1β,interleukin-6,and tumor necrosis factor-alpha were evaluated in kidney tissue.Histopathological study was also performed using hematoxylin and eosin staining.Results:Agmatine at both doses significantly increased final body weight,and lowered fasting blood glucose,urine output,insulin,total protein,albumin,blood urea nitrogen,creatinine,and cystatin-C levels compared with the diabetic group(P<0.05).Inflammatory markers and antioxidant effect were significantly improved in agmatine-treated rats.Moreover,the histopathological changes in renal structure were ameliorated by agmatine treatment.Conclusions:Agmatine alleviates diabetic nephropathy by improving renal functions and reducing inflammation and oxidative stress.The molecular mechanisms of its nephroprotective actions need to be investigated in future study. | Fatemah O.Kamel Ohoud Shagroud Mai AAlim A.Sattar Ahmad Gamal S Abd El-Aziz Abdulhadi S.Burzangi Duaa Bakhshwin Maha Jamal Shahid Karim | 2024 | Asian Pacific Journal of Tropical Biomedicine2024，14，1： | 0 |
