灯盏花胶囊对高糖高脂饮食诱发糖尿病肾病模型的影响
The effect of Erigeron breviscapus capsule on a model of diabetic nephropathy induced by high-sugar and high-fat diet
考察灯盏花胶囊对小鼠糖尿病肾病(diabetic nephropathy, DN)模型的影响,为深入研究提供试验依据.选取9只C57BL/6J小鼠为正常对照,另取70只采用高糖高脂饲料饲喂16周后复制DN模型,将成功复制DN模型的45只小鼠随机分为模型对照、苯那普利(10 mg/kg)以及灯盏花胶囊组(0.78、1.56、3.12 g/kg),每组9只.于给药8周后观察各组小鼠的一般状况,检测各组小鼠尿蛋白、白蛋白(ALB)、空腹血糖(FBG)、空腹胰岛素(FINS)、甘油三酯(TG)、低密度脂蛋白(LDL)、总胆固醇(TC)、谷丙转氨酶(ALT)、谷草转氨酶(AST)、肌酐(Cre)、尿素氮(BUN);HE染色观察小鼠肾脏组织病理形态.结果表明,阳性对照(苯那普利)及各剂量灯盏花胶囊组小鼠一般状况明显改善,24 h尿蛋白及FBG水平降低(P < 0.05/0.01),血清TG、TC、LDL、BUN、Cre和FINS水平降低(P < 0.05/0.01),ALB明显升高(P < 0.05/0.01);肾脏和肝脏指数明显降低,肾组织病理形态学明显改善,与模型对照组比较.表明灯盏花胶囊对早期DN具有一定治疗作用.
To investigate the effect of Erigeron breviscapus capsules on a diabetic nephropathy (DN) model in mice and provide a basis for further study, nine C57BL/6J mice were selected as normal controls, and another 70 mice were fed with high - sugar and high - fat diet for 16 weeks to replicate the DN model. After that, 45 mice were randomly divided into model control, positive control (benazepril, 10 mg/kg) and low dose (0.78 g/kg), medium dose (1.56 g/kg) and high dose groups (3.12 g/kg) doses of Erigeron breviscapus capsules, with nine mice in each group. The general conditions of mice in each group were observed after 8 weeks of administration, and these parameters including fasting blood glucose (FBG), urinary protein, triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), albumin (ALB), alanine transaminase (ALT), aspartate transaminase (AST), creatinine (Cre), urea nitrogen (BUN), fasting insulin (FINS) levels were detected. Histopathological morphology of mice kidney was observed by HE staining. The results showed that compared with the model control group, the general condition of the mice in the positive control and each Erigeron breviscapus capsule dose group was significantly improved, with lower 24 h urine protein and FBG levels (P < 0.05/0.01); lower serum BUN, Cre, TC, TG, LDL and FINS levels (P < 0.05/0.01) and significantly higher ALB (P < 0.05/0.01). Kidney and liver indices were significantly reduced and renal histopathological morphology was significantly improved. Erigeron breviscapus capsules have a therapeutic effect on early DN.
