摘要
目的建立脂多糖(lipopolysaccharide,LPS)/D-氨基半乳糖(D-galactosamine,D-GalN)诱导小鼠急性肝损伤模型。方法 40只雌性C57BL/6小鼠用于观察8种不同LPS与D-GalN剂量配比联合刺激后小鼠存活时间,以确定模型建立的最佳剂量。使用腹腔注射最佳剂量染毒32只雌性C57BL/6小鼠,分别在0、1、4、8 h处死,每组8只,0 h注射相同剂量生理盐水作为对照。观察染毒后小鼠肝组织病理损伤,检测血清中ALT及炎症因子IL-6、MCP-1和TNF-α表达水平变化。结果通过观察小鼠存活时间,确定腹腔注射最佳染毒剂量为LPS(2.5 mg/kg)/D-GalN(0.3 g/kg);小鼠染毒后肝组织呈进程性病变,最终发展为肝脏弥漫性坏死,肝细胞核崩解。与对照组相比,血清ALT显著升高(P<0.001),IL-6、MCP-1、TNF-α均在1 h后达到最高水平(P<0.001),然后持续下降。结论成功建立LPS/D-GaIN诱导小鼠急性肝损伤模型,为探索急性肝损伤的致病机制以及药物干预治疗提供有效的动物模型。
