目的:研究白芍多糖(Paeoniae Radix Alba polysaccharide,PRPY)对D-半乳糖胺/脂多糖诱导小鼠急性肝损伤的保护作用。方法:使用PRPY预先口服给药21 d,采用D-半乳糖胺/脂多糖诱导小鼠急性肝损伤,检测小鼠血清中谷丙转氨酶(ALT)及谷草转氨...目的:研究白芍多糖(Paeoniae Radix Alba polysaccharide,PRPY)对D-半乳糖胺/脂多糖诱导小鼠急性肝损伤的保护作用。方法:使用PRPY预先口服给药21 d,采用D-半乳糖胺/脂多糖诱导小鼠急性肝损伤,检测小鼠血清中谷丙转氨酶(ALT)及谷草转氨酶(AST)、肝组织中超氧岐化酶(SOD)、丙二醛(MDA)、谷胱甘肽过氧化物酶(GSH-Px)活性并结合肝组织病理学检查评价药效。结果:白芍多糖高剂量组能显著降低肝损伤小鼠血清中ALT、AST水平(P<0.01),提高肝组织中SOD、GSH-Px水平同时降低MDA水平(P<0.01),低剂量组则无统计学意义(P>0.05)。肝组织切片病理学检查提示,PRPY可以减轻肝脏组织病理性变化。结论:白芍多糖预先给药对D-半乳糖胺/脂多糖所致的小鼠肝损伤具有一定的预防保护作用,其机制与提高体内氧自由基清除能力相关。展开更多
