摘要 目的:观察柔肝消脂方Rougan Xiaozhi decoction(RXD)对大鼠脂肪肝的治疗作用并初步探讨其作用机制。方法:以高脂饲料(835 g.kg-1标准饲料+15 g.kg-1胆固醇+50 g.kg-1猪油+100 g.kg-1玉米油)喂食6周造成大鼠脂肪肝模型,分为柔肝消脂方高、中、低剂量组(28.8,19.2,9.6 g.kg-1.d-1)、血脂康组(0.1 g.kg-1.d-1)、模型组和正常组等6组,连续给药4周后,检测血液中丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、游离脂肪(FFA)和甘油三脂(TG),检测肝组织低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、超氧化物歧化酶(SOD)、丙二醛(MDA)、一氧化氮(NO)指标。结果:柔肝消脂方高剂量组与模型组比较,血液中ALT[(20.38±7.04),(29.74±6.77)U.L-1,P<0.05],AST[(118.37±5.14),(167.43±15.67)U.L-1,P<0.05],FFA[(453.12±81.36),(1 447.62±205.85)μmol.L-1,P<0.05]和TG[(0.47±0.42),(1.85±1.46)mmol.L-1,P<0.01];肝组织LDL-C[(0.33±0.08),(0.44±0.05)mmol.L-1,P<0.05],HDL-C[(1.03±0.18),(0.78±0.16)mmol.L-1,P<0.05],SOD[(38.72±1.15),(30.81±4.52)U.mg-1,P<0.05],MDA[(2.76±0.25),(6.51±2.66)nmol.mg-1,P<0.01],NO[(32.27±2.65),(83.54±6.21)μmol.L-1,P<0.01],且存在量-效关系,高剂量组的作用程度与血脂康组相当;肝脏脂变程度显著减轻(P<0.01)。结论:柔肝消脂方对大鼠脂肪肝有较好的治疗作用,其机制可能与降低血脂及抗脂质过氧化有关。 Objective: The therapeutical effect of Rougan Xiaozhi decoction (RXD) in rats with fatty liver disease was studied. Method: The rat model with fatty liver disease was established by feeding high fat diet for 6 weeks. Then the rats were randomly divided into 6 groups: RXD groups (high dose, middle dose, low dose), Xuezhikang group, model group and control group. Four weeks later, Liver pathologic changes were observed together with the activity of serum alanine transaminase (ALT), aspartale transaminase (AST), the blood lipid, and the content of liver free fatty acids (FFA), total cholesterol (TG), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), superoxide dismutase (SOD), malonaldehyde (MDA), nitric oxide (NO). Result: Compared with the natural model group, the level of ALT [ (20.38 ± 7.04), (29.74±6.77) U·L^(-1), P〈0.05], AST [ (118.37±5.14), (167.43±15.67) U·L^(-1), P〈 0.05], FFA [ (453.12±81.36), (1447.62±205.85) ~mol·L^(-1), P〈0.05], TG [ (0.47±0.42), (1.85±1.46) mmol·L^(-1), P〈0. 01]; LDL-C [ (0.33±0.08), (0.44±0.05)mmol· L^(-1), P〈O. 05], HDL-C [ (1.03±0.18), (0.78±0.16) mmol· L^(-1), P〈0.05] mmol. L-1, SOD [ (38.72±1.15),(30.81 ±4.52) U.mg-x, P〈0.05], MDA [ (2.76±0.25), (6.51 ±2.66) nmol.mg-1, P〈0.01], NO [ (32.27 ±2.65), (83.54 ±6.21) μmol·L^(-1), P〈0.01], further more it shows dose-effect relation, the effect of high dose group was correspond with Xuezhikang group ; the hepatic steatosis degree were lighten obviously (P 〈0.01). Colaelusion: RXD has a good effect on fatty liver disease. This may lie in decreasing blood lipid and prevention of lipid peroxidation.
