摘    要:探讨虾青素对慢性肝损伤大鼠肝功能的保护作用。方法采用四氯化碳(CCl4)制备大鼠慢性肝损伤模型,设正常组、模型组、虾青素干预组。通过酶联免疫法测定血清丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、碱性磷酸酶(ALP)、总蛋白(TP)以及肝组织超氧化物歧化酶( superoxide dismutase,SOD)、谷胱甘肽转移酶( glutathione-S-transfcrase,GST)活性、谷胱甘肽(glutathione,GSH)及丙二醛(malondialdehyd,MDA)水平。对肝组织病理切片行Masson三色染色,检测肝纤维化情况,采用RT-PCR法检测Ⅰ型胶原mRNA水平。结果正常组大鼠肝胶原指数为(0.42±0.12),模型组大鼠肝胶原指数为(1.84±0.24,P<0.01),虾青素治疗组肝胶原指数为(0.89±0.12),显著低于模型组(P<0.05);正常大鼠肝组织Ⅰ型胶原mRNA水平为(0.12±0.02),模型组为(0.48±0.06,P<0.01),虾青素治疗组为(0.35±0.09),明显低于模型组(P<0.05);正常组肝组织MDA、GST、GSH和SOD水平分别为(1.93±0.76) nmol/mg、(18.43±5.34) U/mg、(75.45±9.67) mg/g、(678.80±76.56) U/mg,模型组MDA和GST分别为(6.56±1.09) nmol/mg、(54.34±7.65) U/mg,均显著升高(P<0.05),而GSH为(35.45±9.01) mg/g,SOD为(203.89±89.00) U/mg,均显著降低(P<0.01);与模型组比,虾青素治疗组MDA为(3.34±1.12) nmol/mg,GST为(30.89±4.78) U/mg,均显著低于模型组(P<0.01),而GSH为(56.78±7.78)mg/g,SOD为(432.34±92.56) U/mg,均较模型组显著升高(P<0.01)。结论虾青素可以缓解四氯化碳诱导的大鼠慢性肝损伤,其可能机制与提高抗氧化能力有关。

Abstract:To investigate the effects of astaxanthin on chronic liver injury in rats and to explore the underlying mechanism. Methods Chronic liver injury in rats were induced by carbon tetrachloride injection, and the rats were randomly divided into control,model and astaxanthin group. The content of ALT,AST,ALP,TP in serum and superoxide dismutase (SOD),glutathione-S-transfcrase (GST),glutathione (GSH) and malondialde-hyd (MDA) in liver tissues were detected. The collagensⅠmRNA were detected by RT-PCR. Results The colla-gens index in model group were (1.84±0.24),much higher than in control (0.42±0.12),P﹤0.05],while the colla-gens index in astaxanthin group (0.89±0.12) decreased significantly (P﹤0.05) as compared to that in the model;The collagenⅠmRNA in model group (0.48±0.06) was higher than in control group (0.12±0.02),while it de-creased (0.35±0.09) in astaxanthin group (P﹤0.01) as compared to that in the model;In control group,the MDA, GST,GSH and SOD in liver tissues were (1.93±0.76) nmol/mg, (18.43±5.34) U/mg,(75.45±9.67) mg/g and (678.80±76.56) U/mg,respectively. They were (6.56±1.09) nmol/mg,(54.34±7.65) U/mg,(35.45±9.01) mg/g and (203.89±89.00 U/mg),respectively. After treatment of astaxanthin,they were(3.34±1.12) nmol/mg,(30.89±4.78) U/mg,(56.78±7.78) mg/g and (432.34±92.56 U/mg),respectively. Conclusion Astaxanthin could attenuate chronic liver injury in rats by improving the anti-oxidative stress.
Keywords:Chronic liver injury  Astaxanthin  Protective effect  Oxidative stress
