【 摘 要 】

Background & objectives: Several studies have shown that pentoxifylline is an antioxidant and anti-inflammatory agent. Pentoxifylline (PTX), has been shown to exert protective effects on autoimmune disorders. The objective of the present study was to examine the effect of pentoxifylline on histopathology of pancreas in diabetic mice.Methods: Diabetes was induced by multiple injection of low-dose streptozotocin (40 mg/kg/day for 5 consecutive days) in male C57BL/6 mice. After induction of diabetes, mice were treated with pentoxifylline (100 mg/kg/day i.p.) for 21 days. The nitric oxide levels were evaluated in spleen cell culture supernatant. Pancreases were isolated and stained by hematoxylin & eosin (H&E) and Gomori aldehyde fuchsin (GAF).Results: Pentoxifylline treatment significantly inhibited the production of nitric oxide (p<0.05). In addition, PTX improved the pancreas tissue. It increased the mean diameter of islets and the number of islets and beta cells. (p<0.05).Conclusion: These findings indicated that pentoxifylline might have a therapeutic effect against the autoimmune destruction of the pancreatic beta-cells during the development of STZ-induced type 1 diabetes in mice.
