摘要: 目的:探讨糖尿病对大鼠重要器官组织抗氧化水平的影响。方法:90日龄Wistar大鼠24只,随机分为正常对照组(C)、胰岛素治疗糖尿病组(ID)和糖尿病组(D),每组8只,取大鼠器官组织用比色法测定GSH-Px、GSH和GR水平变化。结果:D组与C组比较大鼠 心、肾、胰腺组织GSH-Px水平升高(P<0.05或P<0.01),D组与ID组比较肝组织GSH-Px水平升高,但差异无显著性,脾组织GSH-Px水平无变化;而大鼠心、肝、肾、胰、脾组织GSH、GR水平均降低(P<0.05或P<0.01);经胰岛素治疗后,5个器官组织中GSH-Px、GSH和GR水平均有改善。 结论:经胰岛素治疗后,糖尿病大鼠重要器官组织抗氧化水平有不同程度改善。

Abstract: Objective To explore the effects of diabetes on anti-oxidation levels of key organs and tissues in rats. Methods Twenty-four Wistar rats for 90 days were randomly divided into three groups : control group (C), diabetes treated with insulin group (ID) and diabetes group(D). There were 8 rats in each group. The changes of levels of GSH-Px, GSH, and GR in rat organs and tissues were detected by colorimetric method. Results Compared with group C, GSH-Px levels in heart, kidney, and pancreas in group D were significantly ascended (P<0.01 or P<0.05); it was ascended in liver, but there wasn′t statistical significance (P>0.05), and the GSH-Px level was not changed in spleen. GSH and GR levels in group D were significantly descended in heart, liver, kidney, spleen, and pancreas compared with group C (P<0.01 or P<0.05); but they were alleviated after insulin was administered. Conclusion The anti-oxidation levels in important organs and tissues of diabetic rats may be improved after insulin therapy.
