罗格列酮干预大鼠非酒精性脂肪肝

目的：用马来酸罗格列酮治疗非酒精性脂肪肝大鼠,观察治疗前后胰岛素抵抗情况、血浆载脂蛋白CII（ApoCII）、载脂蛋白CIII（ApoCIII）的含量变化和脂蛋白脂肪酶（LPL）、肝脂肪酶（HL）的活性变化,肝组织载脂蛋白B100（Apo-B100）mRNA表达量和病理学变化。方法：用高脂肪高胆固醇饮食饲养SD雄性大鼠8周建立大鼠脂肪肝模型成功后对大鼠用马来酸罗格列酮治疗4周;HE染色观察大鼠肝脏病理学变化,逆转录-聚合酶链反应（RT-PCR）法检测大鼠肝脏Apo-B100mRNA表达,用酶联免疫吸附试验（ELISA）法检测大鼠血浆ApoCII、ApoCIII、胰岛素含量,用酶法检测大鼠LPL、HL的活性,快糖仪测大鼠空腹血糖,根据HOMA-IR公式[IR=FPG（mmol/L）×FINS（mIU/L）/22.5]计算胰岛素抵抗指数。结果：脂肪肝大鼠经马来酸罗格列酮干预治疗后胰岛素抵抗和肝细胞脂肪变性较治疗前减轻,肝组织中Apo-B100mRNA表达量增加;ApoCII含量升高,ApoCIII含量降低;LPL、HL活性升高。结论：马来酸罗格列酮可以减轻脂肪肝大鼠的胰岛素抵抗,改善其脂质代谢紊乱,减轻其肝细胞脂肪变性。

Rosiglitazone Intervene Nonalacoholic Fatty Liver Disease Rats' Experimental Study

Objective:To observe the variation of insulin resistance and plastic apolipoprotein-CII,apolipoprotein-CIII content and the plastic activity of lipoprotein lipase,hepatic lipase,apolipoprotein-B100mRNA representation and patholotic varation of hepatic tissue of the rosiglitazone maleate therapy of nonalcoholic fatty liver disease rats.Methods: Male Sprague Dawley rats fed with hpysi-fat and hpysi-cholesterol forage for establishing nonalacoholic fatty liver disease model for 8 weeks,the nonalacoholic fatty ...
