黄丹益肾胶囊对糖尿病肾病大鼠的防治作用实验研究

Effect of Huangdanyishen Capsule on diabetic nephropathy of experimental rats

目的:为观察黄丹益肾胶囊(黄芪、丹参)(HDC)对糖尿病肾病(DN)大鼠的治疗作用。方法:采用高糖、高脂、高胆 固醇饲料喂养Wistar大鼠致胰岛素抵抗后用链脲佐菌素(STZ)诱发糖尿病肾病大鼠模型,形成高血糖后随机分为5组, 连续给药10周,观察用药前后大鼠一般情况、血糖,10周后测定肾功能指标并作病理组织学检查。结果:黄丹益肾胶囊 能明显改善Ⅱ型糖尿病肾病大鼠的精神状况,增加大鼠体重,减少大鼠的24h尿量;降低Ⅱ型糖尿病肾病大鼠血清肌苷 和尿素氮的含量,降低尿微量白蛋白的含量;减轻高血糖引起的大鼠肾小球基底膜(GBM)增厚、触突排列紊乱融合、线 粒体肿胀变性等病理改变,可较好地保护DN大鼠肾脏的超微组织结构;并有一定的降糖作用;结论:提示黄丹益肾胶囊 对Ⅱ型糖尿病肾病有明显的防治作用,同时还有一定的降糖作用。

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.
