AIM: To observe the efficacy of Huangdanyishen Capsule (HDC)(Radix Astragali, Radix Salviae Miltiorr hizae) on renal lesions in diabetic nephropathy(DN) rat induced by Streptozocin(STZ). METHODS: The murine model with DN induced by STZ was made from Wistar rats with insulin resistance after being fed with feedingstuff of hypersugar, hyperlipid, hypercholesterol. These rats were randomly divided into five groups, and all rats were successively administrated corresponding drugs for 10 weeks. The general state and blood sugar were observed during the period. Serum urea nitrogen and creatinine content, the excretory rate of urinary micro-protein and renal pathological features were determined after 10 weeks. RESULTS: HDC could obviously ameliorate psychic status and renal function of rats with diabetes mellitus Ⅱ, and increase DN rats' weight. HDC could reduce the content of DN rats' serum urea. nitrogen and creatinine and urinary micro-protein. The ultramicropathologic histopathologic results indicated that the glomerular basement membrane thickening, synapse displaying foul-up and amalgamation, and mitochondrial swelling were alleviated to a certain extent in HDC groups. The content of murine blood sugar in HDC groups was significantly lower than those in model group. CONCLUSION: HDC has an obvious effect on Ⅱ DN treatment and decrease the content of blood sugar at the same time.

Objective To study the effect of Buyang Huanwu Decoction (BHD) on adhesion molecules in vascular endothelial cells (VECs) of blood stasis rats. Methods Expression of ICAM-1, VCAM-1, PECAM-1, iNOS in vascular endothelial cells of blood stasis rats receiving different doses of BHD was observed by immunohistochemical method and RT-PCR.Results The expression of ICAM-1, VCAM-1, PECAM-1, iNOS was increased in model group, while was decreased by BHD. There was an increase tendency on the expression of molecules and significant dose-effect relationship along with the decrease of the BHD doses. Conclusion The increased expression of adhesion molecules in vascular endothelial cells of blood stasis rats could be reduced by BHD in a dose dependent manner.

AIM: To study the effects of xijiao dihuang decoction, a Chinese medicine, on the expression of adhesion molecules in vascular endothelial cells (VECs) of adrenine and hypothermia-treated rats. METHODS: The expression of VCAM-1, ICAM-1, PECAM-1, iNOS and their corresponding mRNA in VECs was assayed by immunohistochemistry analysis and RT-PCR, respectively. RESULTS: Immunohistochemistry analysis showed the expression of VCAM-1, ICAM-1, PECAM-1 and iNOS are higher in adrenine and hypothermia-treated rats than that in controls, xijiao dihuang decoction decreased the expression of VCAM-1, ICAM-1, PECAM-1 and iNOS in a dose-dependent manner in adrenine and hypothermia-treated rats. CONCLUSION: Xijiao dihuang decoction can down-regulate the expression of adhesion molecules in vascular endothelial cells of adrenine and hypothermia-treated rats.
