目的:研究蓝莓对酒精性脂肪肝(AFLD)小鼠肝组织中血红素氧化酶-1(HO-1)表达水平及抗氧化能力的影响,探讨蓝莓对AFLD的保护作用及可能机制。方法:40只C57/6J小鼠随机均分为对照组、蓝莓组、蓝莓+HO-1抑制剂(锌原卟啉,ZnPPIX)组及模型组,NIAAA法建立AFLD动物模型,油红O染色法检测模型建立情况及各组小鼠肝组织病理学变化;取眼眶血检测各组小鼠血清谷丙转氨酶( ALT),谷草转氨酶( AST),甘油三脂( TG),胆固醇( TC)含量;酶联免疫吸附法( ELISA)测定各组小鼠肝组织中超氧化物歧化酶( SOD)活性及谷胱甘肽( GSH)、丙二醛( mDA)的含量;Western blot法检测各组小鼠肝组织中HO-1蛋白的表达。结果:蓝莓组肝组织脂肪沉积较模型组及蓝莓+ZnPPIX组明显减少,血清中ALT、AST、TG及TC含量降低( P<0.05),肝组织中SOD活性和GSH含量升高( P<0.05),mDA含量降低( P<0.05);蓝莓组HO-1蛋白表达量高于蓝莓+Zn-PPIX组及模型组。结论:蓝莓可减轻AFLD,其机制可能与上调小鼠肝脏HO-1的表达,增强机体抗氧化能力有关。

Objective:To investigate the influence of blueberry on heme oxygenase-1( HO-1 )and antioxidant ability of mice with alcoholic fatty liver disease( AFLD ),and to explore the protective effects of blueberry on AFLD and possible mechanism. Methods:Forty C57/6J mice were randomly divided into control group,blueberry group,blueberry+ZnPPIX group and model group. AFLD model was established by using NIAAA method,pathological changes in the hepatic tissues were detected by oil red O staining,the orbital blood was taken to detect the levels of alanine aminotransferase( ALT), aspartate aminotransferase(AST),triglyceride(TG)and total cholesterol(TC). The superoxide dis-mutase( SOD)activity and glutathione( GSH)levels,malondialdehyde( mDA)contents inliver tissue were quantified by ELISA. The expression of HO-1 in liver tissue was detected by Western blot. Re-sults:Compared with model group and blueberry+ZnPPIX group,lipid accumulation in liver tissue of mice in blueberry group decreased,serum ALT,AST,TG and TC levels decreased( P<0. 05 ). The hepatic mDA content also decreased( P <0. 05 ),while GSH contents,SOD activity and the HO-1 levels increased(P<0. 05). Conclusion:Blueberry can alleviate AFLD,the mechanism may relate to raise the expression of HO-1 in mice,increase the antioxidant capacity.
