Effect of Huangdanyishen Capsule on diabetic nephropathy of experimental rats / 中成药

ABSTRACT

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.
