牡蛎肝宝对大鼠酒精性肝病的抗脂质过氧化作用

目的:观察牡蛎肝宝对大鼠酒精性肝病(alcoholic liver disease,ALD)的防治作用及其抗脂质过氧化效应.方法:采用给予乙醇灌胃制造酒精肝模型的方法,75只♂Wistar大鼠随机均分为空白组、模型组以及牡蛎肝宝低剂量、中剂量、高剂量5组.模型组仅给予500 mL/L的乙醇灌胃8wk,治疗组给予同等量乙醇灌胃,同时还给分别给予低剂量、中剂量和高剂量牡蛎肝宝8wk.空白对照组每天仅给予等量蒸馏水灌胃8 wk.治疗结束后,抽取大鼠腹主动脉血液,检测血清ALT、AST、TG、TC、GLU及丙二醛加合物抗体IgG,同时取大鼠肝脏做冰冻切片,用苏丹Ⅲ染色,观察各组脂肪变程度.结果:空白组及牡蛎肝宝中、高剂量组血清ALT、AST、TG、TC、GLU均明显低于模型组(均P<0.01),牡蛎肝宝中、高剂量组血清丙二醛加合物抗体IgG浓度低于模型组(P<0.01),牡蛎肝宝低剂量组血清ALT、AST和GLU低于模型组(63.67 U/L±6.89 U/L vs 81.53 U/L±22.85 U/L,131.2 U/L±11.63 U/L vs 156.47U/L±32.23 U/L,6.38 mmol/L±0.66 mmol/Lvs 6.86 mmol/L±0.67 mmol/L,P<0.01或0.05):模型组肝脏病理改变的程度高于空白对照组(P<0.01):牡蛎肝宝中、高剂量组肝脏病理改变的程度均低于模型组(P<0.05).结论:牡蛎肝宝可以降低ALD的肝脏脂质蓄积,抗脂质过氧化,有保肝降酶作用.

Anti-lipid peroxidation effects of taurine ganbo in rats with alcoholic liver disease

AIM:To observe the protective and therapeutic effects and anti-lipid peroxidation effects of taurine ganbo in rats with alcoholic liver disease.METHODS:A rat model of alcoholic liver disease was established by intragastric infusion of alcohol.Seventy-five male Wistar rats were randomly divided into five groups:normal control group,model group,low-dose taurine ganbo group,middle-dose taurine ganbo group, and high-dose taurine ganbo group.The model group was given dehydrated alcohol(500 mL/L) once a day for 8...
