The study on the intrareal RAS components gene expression shows: the intrareal angiotensin II concentration and the renal cortex ACE activity of diabetic rats were significantly upregulated, the ATi mRNA content was significantly downregulated.

• 对肾脏RAS基因表达研究结果表明：DC组肾脏Ang浓度、肾皮质ACE活性均较NC组显著升高，AT_1 mRNA相对含量显著下降； 治疗两组(D+Ena、D+XSW)肾脏Ang、肾皮质ACE活性浓度均比DC组有显著下降，两组之间无显著差异。
