摘要 目的:研究新疆紫草提取物AEJ-I、AEJ-Ⅱ对小鼠免疫性肝损伤的保护作用。方法:采用卡介苗(BCG)和脂多糖(LPS)诱导免疫性肝损伤动物模型,观察AEJ-I、AEJ-Ⅱ对小鼠肝脏系数、脾脏系数及血清丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、肝组织超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、丙二醛(MDA)和一氧化氮(NO)水平的影响,并观察肝脏病理组织学变化。结果:AEJ-I高剂量组和AEJ-Ⅱ高、低剂量组均可降低肝脏系数,并使肝组织MDA含量降低(P<0.05或P<0.01);AEJ-I高剂量组可降低脾脏系数,并使肝组织SOD活性升高(P<0.05);AEJ各剂量组均可使肝组织GSH-Px活性升高、NO含量降低(P<0.05或P<0.01);AEJ-I高剂量组可明显降低小鼠血清ALT、AST的活性(P<0.01或P<0.05);AEJ-Ⅱ高、低剂量组均可明显降低小鼠血清ALT的活性(P<0.05),AEJ-Ⅱ高剂量组可明显降低小鼠血清AST的活性(P<0.05)。AEJ-I、AEJ-Ⅱ均可不同程度地改善肝脏病理组织性损伤。结论:AEJ-I和AEJ-Ⅱ对小鼠免疫性肝损伤具有保护作用。 Objective: To study the protective effects of Arnebia euchrorna (Royle) Johnston extracts, fatsoluble(AEJ-Ⅰ) and water soluble (AEJ-Ⅱ ) against the immunological liver injury in mice. Methods: The immunological liver injury animal model was established in mice by injection of Bacillus Calmette-Guerin (BCG) and lipopolysaccharide (LPS). The coefficient of liver and spleen; alanine aminotransferase (ALT) and aspartate amiontransferase(AST) activities in serum; superoxide dismutase (SOD) glutathione peroxidase(GSH-Px) activities, malondialdehyde (MDA) and nitrous oxide (NO) content in liver homogenate were assayed and hepatic pathological changes were observed. Results: AEJ-Ⅰ(0.8 g/kg)and AEJ-Ⅱ (2, 4 g/kg)decreased the coefficient of liver and the content of MDA (P 〈0.05 or P 〈0.01) ; AEJ-Ⅰ(0.8 g/kg) decreased the coefficient of spleen and increased the activity of liver homogenate SOD (P〈0.05) ; AEJ-Ⅰ (0.4, 0.8 g/kg)and AEJ-Ⅱ (2, 4 g/kg)increased the activity of liver homogenate GSH-Px and decreased the content of NO (P 〈0.05 or P 〈0.01); AEJ-Ⅰ (0.8 g/kg)decreased the activity of serlum ALT and AST (P 〈0.01 or P 〈0.05), AEJ-Ⅱ (2, 4 g/kg) decreased the activity of serlum ALT (P 〈0.05). AEJ-Ⅱ (4 g/kg) decreased the activity of serum AST (P 〈0.05). AEJ-Ⅰ and AEJ-Ⅱ improved liver histopathology injuries. Conclusions: AEJ-Ⅰ and AEJ-Ⅱ showed protective effects on the immunological liver injury in mice.
