摘要: 目的:探讨丹蛭降糖胶囊对糖尿病模型大鼠心脏和肾组织病理学变化的影响。方法:雄性SD大鼠70只,随机选取10只作为正常组,普通饲料饲养,其余大鼠高脂饲料喂养4周,腹腔注射链脲佐菌素(STZ)34 mg/kg制作Ⅱ型糖尿病大鼠模型,造模不成功大鼠腹腔注射补注STZ 25 mg/kg。成模大鼠根据血糖、体质量分为4组:模型组、高剂量[1.08 g/(kg·d)]丹蛭降糖胶囊组、低剂量[0.54 g/(kg·d)]丹蛭降糖胶囊组、吡咯列酮组[10 mg/(kg·d)],每组10只。正常组、模型组大鼠给予同体积生理盐水。连续灌胃给药6周,测定大鼠一般体征指标,全自动生化分析仪检测血糖、血脂、肾功能指标(BUN、Scr、mAlb、尿蛋白量),心脏组织采用HE及MASSON染色,肾组织采用HE、MASSON及糖原PAS染色,观察组织的病理变化。结果:与正常组相比,模型组大鼠体质量下降,摄食量、摄水量明显增加,血糖、血脂、肾功能指标升高(P < 0.01),病理组织学观察可见心脏炎性细胞浸润,心肌纤维化增加,肾脏包曼氏囊结构改变,细胞质基质增多,纤维化程度明显增加。给药6周后,与模型组比较,吡咯列酮组、高、低剂量丹蛭降糖胶囊组大鼠体质量明显增加,摄食量、摄水量下降(P < 0.01),病理学观察可见心脏、肾脏各项病变均有所减缓。吡格列酮组、高剂量丹蛭降糖胶囊组血糖、血脂、肾功能指标下降(P < 0.05或P < 0.01),低剂量丹蛭降糖胶囊组大鼠血糖、血脂、肾功能指标虽下降,但TC水平差异无统计学意义(P > 0.05),且HbAlc、TG、TC、mAlb水平与吡格列酮组存在统计学差异(P < 0.05或P < 0.01)。结论:高剂量丹蛭降糖胶囊能有效地改善大鼠的血糖血脂水平,缓解多饮、多食症状,并可减轻高血糖对大鼠心肌及肾脏组织的损害。

Abstract: OBJECTIVE: To explore the effect of Danzhijiangtang capsule on pathological changes of heart and kidney in diabetic rats. METHODS: 70 male SD rats,randomly selected 10 as normal group,the average feed,the rest 4 weeks rats a high-fat feed,intraperitoneal injection of chain urea with streptozotocin (STZ) 34 mg/kg copy type Ⅱ diabetic rat model,building is not successful rats intraperitoneal injection of STZ injection 25 mg/kg. The model rats were divided into four groups of 10 rats per group according to blood glucose and volume:model group,high-dose Danzhijiangtang capsule group[1.08 g/(kg·d)],low-dose Danzhijiangtang capsule group[0.54 g/(kg·d)],and pionlitazone group[10 mg/(kg·d)]. The normal group and the model group were given the same volume of normal saline. Blood glucose,blood lipid,renal function (BUN,Scr,mAlb,urinary protein) were detected by automatic biochemical analyzer. Cardiac tissues were stained with HE and MASSON,and renal tissues were stained with HE,MASSON and glycogen PAS. Pathological changes of tissues were investigated. RESULTS: Compared with the normal group,the model group rats showed decreased volume,significantly increased food intake and water intake,blood sugar,blood lipid and renal function index (P < 0.01). In addition,they showed visible infiltration of heart inflammatory cells,increased myocardial fibrosis,changes in kidney baumann's capsule structure,and significantly increased cytoplasmic matrix and the degree of fibrosis. After 6 weeks of administration and compared with the model group,the volume of pioglitazone group and the high-dose Danzhijiangtang capsule group significantly increased,the food intake and water intake decreased,and the indexes of blood glucose,blood lipid and kidney function decreased (P < 0.05,P < 0.01). In addition,the pathological changes of heart and kidney slowed down. Although the indexes of blood glucose,blood lipid and renal function of rats in the low dose danzhu hypoglycemic capsule group decreased,there was no significant difference from the TC level (P > 0.05). However,there were statistical differences between the levels of HbAlc,TG,TC and mAlb and those in the pyrrolitazone group (P < 0.05,P < 0.01). CONCLUSION: Administration of either high or low dose Danzhijiangtang capsules effectively reduced blood glucose and lipid levels in rats,relieved the symptoms of polyphagia and polydipsia,and reduced the damage of hyperglycemia in myocardial and renal tissues of rats.
