Abstract:To explore the preventive and curative mechanism of Jianpijiangtang Solution(JS) on diabetes rats and its chronic complications, we observed the effect of JS on blood sugar,blood rheology changes, serum nitric oxide(NO) and plasma endothelin (ET) of diabetes rats induced by alloxan. The results showed that JS could improve the blood rheoligy, decrease blood sugar and plasma ET level, and raise serum NO level. The effects of JS on NO and ET are of great importance in diabetes rats and its chronic complications.
