摘要

本研究旨在探讨活化的诱导型一氧化氮合酶(iNOS)和一氧化氮(NO)对链脲佐菌素(STZ)诱导的糖尿病小鼠肾脏组织的影响,以及iNOS特异性抑制剂氨基胍(AG)是否可以预防其影响。24只雄性小鼠被分为4个研究组(n=6),每天服用100 mg。kg-1 AG治疗90天(AG组),单次剂量150 mg。kg-1 STZ (STZ组),单次剂量150 mg。kg-1 STZ,然后每日给药100 mg。STZ-AG组腹腔注射生理盐水90 d,对照组腹腔注射生理盐水90 d。与对照组相比,stz处理的动物肾脏组织中NADPH-diaphorase (NADPH-d)的弥散性更强。STZ治疗导致近端小管刷状边界连续性中断,肾小球内皮损伤,肾小球旁细胞出现大量肾素颗粒。STZ治疗后给予AG部分阻止肾皮质组织学和细胞学改变,肾素弥散与对照动物相似。我们发现,诱导型一氧化氮(iNO)升高可引起肾组织变性,而AG处理可在一定程度上预防这种变性。糖尿病肾小球旁细胞中iNOS的增加与肾素颗粒的分散可能有关。

The effect of aminoguanidine on the kidney of diabetic albino Balb/c mice
The aim of this study is to find out how activated inducible nitric oxide synthase (iNOS) and nitric oxide (NO) affect kidney tissue in streptozotocin (STZ)-induced diabetic mice and whether its influence can be prevented by aminoguanidine (AG), a specific iNOS inhibitor. Twenty-four male mice were divided into four study groups (n=6) receiving a daily dose of 100 mg.kg-1 AG for 90 days (Group AG), a single dose of 150 mg.kg-1 STZ (Group STZ), a single dose of 150 mg.kg-1 STZ followed by daily administration of 100 mg.kg-1 AG for 90 days (Group STZ-AG), and intraperitoneally injections of saline only (Group Control) for 90 days. Dispersion of NADPH-diaphorase (NADPH-d) was stronger in the kidney sections of STZ-treated animals compared with the controls. STZ treatment caused disruption of continuity of the brush borders in proximal tubules, glomerular endothelial damage, and considerable renin granules in the juxtaglomerular cells. AG administration following STZ treatment partly prevented histological and cytological changes in kidney cortex, and renin dispersion was similar to that in control animals. We found that increased inducible nitric oxide (iNO) caused kidney tissue degeneration that could be prevented to some extent by AG treatment. There is a possible relationship between increased iNOS and dispersion of renin granules in juxtaglomerular cells in diabetes.
