摘要
目的:观察F1013对D-氨基半乳糖(D-GalN)及脂多糖(LPS)所致大鼠急性肝衰竭模型的保护作用,并对其机制进行初步探讨。方法:采用D-GalN/LPS诱导大鼠急性肝衰竭模型,用全自动生化分析仪检测血清ALT、AST和总胆红素(TBIL)含量;用苏木素-伊红(HE)染色,观察肝组织病理学变化;采用流式细胞学技术和原位末端标记(TUNEL)法检测肝细胞凋亡情况。结果:模型组大鼠血清ALT、AST、TBIL水平和肝细胞凋亡率较正常对照组均显著升高(P<0.01)。F1013(5,2.5,1.25 mg/kg)给药组大鼠肝组织病理损伤程度明显轻于模型组;血清ALT、AST水平和肝细胞凋亡率均较模型组明显降低(P<0.01或P<0.05),另F1013(5 mg/kg)给药组血清TBIL水平较模型组明显降低(P<0.01)。结论:F1013对GalN/LPS引起的大鼠急性肝衰竭有较好的保护作用,其机制可能与抑制肝细胞凋亡有关。
AIM:To observe the protective effect of F1013 on fulminant hepatic failure(FHF) induced by lipopolysaccharide(LPS) plus D-galactosamine(D-GalN) in rats and to investigate its mechanism of action. METHODS:The rat model of FHF was induced by intra-peritoneal injection of LPS plus D-GalN.The contents of ALT,AST and total bilirubin(TBIL) were examined by an entire automatic biochemistry,the hepatic pathological changes were observed with hematoxylin-eosin(HE) stain,and the hepatocyte apoptosis was detected with FCM and TUNEL.RESULTS:Compared with the control group,serum levels of ALT,AST and TBIL and the expression of hepatocyte apoptosis in rats of the model group were significantly elevated(P0.01).Compared with the model group,5,2.5,1.25 mg/kg F1013 treatment groups could effectively improve the hepatic tissue injury,reduce serum levels of ALT and AST and the expression of hepatocyte apoptosis(P0.01 or P0.05),5 mg/kg F1013 treatment group reduce serum levels of TBIL(P0.01).CONCLUSION:It is shown that F1013 has a promising protective effect on rats with FHF caused by LPS plus D-GaIN,and its mechanism is probably related to the inhibition of liver tissue cell apoptosis.
