布芍调脂胶囊对非酒精性脂肪肝大鼠脂质水平、肝功能、血液流变学及肝脏病理形态的影响

Effects of Bushao Tiaozhi Capsule on lipid level,liver function,hemorheology and liver pathological morphology in rats with nonalcoholic fatty liver disease

目的观察布芍调脂胶囊对高脂饮食诱导的非酒精性脂肪肝模型大鼠脂质水平、肝功能及血液流变学的影响。方法将大鼠随机分为正常组、模型对照组、阿托伐他汀组[1.8 mg/(kg·d)]、布芍调脂胶囊高、中、低剂量组[5.76 g生药/(kg·d)、2.88 g生药/(kg·d)、1.44 g生药/(kg·d)],每组各8只,正常组给予普通饲料,其余组给予高脂饲料,造模8周后给予药物治疗。给药4周后,HE及油红O染色观察肝脏病理形态变化,检测大鼠血清及肝脏脂质水平,肝功能及血液流变学变化。结果高脂饮食后大鼠出现脂肪肝病理形态变化,血清胆固醇(total cholesterol,TC)、甘油三酯(triglyceride,TG)、低密度脂蛋白(low density lipoprotein cholesterol,LDL-C)水平及丙氨酸氨基转移酶(alanine a minotransferase,ALT)及天门冬氨酸氨基转移酶(alanine a minotransferase,AST)含量显著升高(P<0.01),血清高密度脂蛋白(high density lipoprotein cholesterol,HDL-C)水平及血清超氧化物歧化酶(superoxide dismutase,SOD)水平显著降低(P<0.01),肝脏TC、TG水平及肝脏系数显著升高(P<0.01),全血黏度低、中、高切均显著性降低(P<0.01)。与模型组相比,布芍调脂胶囊高、中、低剂量组血清TC、TG、LDL-C及ALT、AST水平水平显著性降低(P<0.01),布芍调脂胶囊高、中、低剂量组SOD水平显著性升高(P<0.01),布芍调脂胶囊高剂量组血清HDL-C水平显著性升高(P<0.01),布芍调脂胶囊高、中、低剂量组肝脏TC、TG水平及肝脏系数显著性降低(P<0.01或P<0.05),布芍调脂胶囊高、中剂量组全血黏度低、中、高切显著性升高(P<0.01);布芍调脂胶囊低剂量组全血黏度中切显著性升高(P<0.05),全血黏度高切显著性升高(P<0.01)。结论布芍调脂胶囊具有保护肝功能及抗氧化的能力,能降低血液黏度,可能通过活血化痰治疗非酒精性脂肪肝病。

Objective To observe the effects of Bushao Tiaozhi Capsule(BSTZC)on lipid level,liver function and hemorheology in rats with nonalcoholic fatty liver disease induced by high fat diet.Methods Rats were randomly divided into model control group,atorvastatin group,BSTZC high-dose group,middle-dose group and low-dose group,8 rats in each group.They were fed with high fat diet for 8 weeks,and the other 8 rats were taken as normal control group.After 4 weeks of administration,the serum and liver lipid levels,liver function and hemorheology changes were detected,and the pathological changes of liver were observed.Results After the high-fat diet,the pathological changes of fatty liver,the increase of blood lipid and liver lipid,the damage of liver function and the increase of blood viscosity were significant.BSTZC can significantly reduce the blood and liver lipid level of nonalcoholic fatty liver model rats,improve liver function and blood viscosity,and improve the pathological changes of fatty liver.Conclusion BSTZC may treat NAFLD by activating blood circulation and resolving phlegm.
