摘要: 目的: 研究荔枝核皂苷和罗格列酮对高脂血症-脂肪肝大鼠血糖血脂的影响。方法: 采用高脂血症-脂肪肝大鼠模型, 观察荔枝核皂苷和罗格列酮、格列齐特对病鼠空腹血糖(FBG)、口服葡萄糖耐量试验(OGTT) 后2 h 血糖(2hBG) 以及给药后2 h 空腹血清血糖(FSG)、总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白-胆固醇(HDL-C)、低密度脂蛋白-胆固醇(LDL-C)、血清尿素氮(BUN)、肌酐(Cr)、丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST) 及镜检肝组织病理学等指标的影响。结果: 荔枝核皂苷和罗格列酮能显著改善高脂血症-脂肪肝致胰岛素抵抗(IR) 模型大鼠的IGT, 降低OGTT 后2h BG 和FSG(P <0.05);并能显著降低病鼠TC、TG、LDL-C 含量(P <0.05~0.01), 显著提高HDL-C 含量(P <0.05);降低病鼠ALT、AST 活性和BUN、Cr 含量(P<0.05), 改善肝细胞脂肪变性(P <0.01) 。结论: 荔枝核皂苷和罗格列酮能提高胰岛素的敏感性, 调整高脂血症-脂肪肝所致的糖脂代谢障碍, 并具有改善病鼠肝肾功能的作用。

Abstract: AIM: To investigate the effects of saponin of Litchi seed (SL) and roglitazone on decreasing blood glucose, Lipid and amelioration hepatic, nephritic function in hyperlipemia-fatty liver rats fed by high-sugarfat.METHODS: The animal model with hyperlipemiafatty liver was prepared in rats by feeding on high caloric diet (abounded of sugar and fat) for 10 weeks.After 6 weeks treatment, the effects of SL, roglitazone and gliclazide (intragastrointestinally administered, qd for 4 weeks) on fasting blood glucose (FBG), 2-hour blood glucose (2hBG) after oral glucose tolerance test (OGTT), serum contents of fasting glucose(FSG), total cholesterol(TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood urea nitrogen (BUN), creatine (Cr) and serum activities of alanine aminotransferase (ALT), and aspartate aminotransferase (AST) and hepatic histopathology were observed by microscope.RESULTS: After administration of SL and roglitazone, the serum concentrations of fasting blood glucose (FSG) and 2-hour blood glucose (2hBG) after oral glucose tolerance test (OGTT) significantly decreased (P <0.05);the impaired glucose tolerance (IGT) improved;the level of TG, TC, and LDL-C decreased (P <0.05);the content of HDL-C augmented (P <0.05);the concentrations of BUN and Cr, activities of ALT and AST decreased (P <0.05);and the fatty degeneration of hepatocytes improved (P <0.01). CONCLUSION: SL and roglitazone can control hyperinsulinemia, enhance insulin sensitivity, reduce level of blood glucose, regulate components and contents of blood lipid, and improve both of function in liver and kidney.
