摘要: 探讨黔产毛蒟水提物(PTE)对四氯化碳(CCl4)诱导小鼠急性肝损伤的保护作用及其作用机制。本研究中将50只昆明种小鼠随机分为5组,各组10只,分别为空白组、模型组(0.01 g/kg的0.15%CCl4菜油溶液造模)、PTE组(低剂量组0.5 g/kg和高剂量组1.0 g/kg)和阳性对照组(联苯双酯0.15 g/kg)。检测各组小鼠谷丙转氨酶(ALT)、谷草转氨酶(AST)、肿瘤坏死因子(TNF-α)含量;测定肝组织匀浆中脂质过氧化产物丙二醛(MDA)含量及超氧化物歧化酶(SOD)活性;计算肝脏的湿重指数;HE染色法观察肝脏组织的病理学变化。与空白对照组相比,模型组血清ALT、血清AST、肝脏指数、肝组织MDA含量以及血清TNF-α明显增高(均P<0.01),肝组织SOD活性明显降低(P<0.01),肝组织病理损伤明显。与模型组相比,PTE高剂量组和阳性对照组血清ALT显著降低(P<0.01),PTE低、高剂量组和阳性对照组血清AST、肝脏指数、肝组织MDA含量以及血清TNF-α含量均明显降低(P<0.05或P<0.01),肝组织SOD活性明显升高(P<0.01),并减轻了肝组织病理损害。PTE可减轻CCl4诱导的急性肝损伤,其机制可能与抗氧化、抑制TNF-α的产生有关。

Abstract: The aim of this study was to investigate the protective effects of Piper puberulum(Benth.) Maxim water extract(PTE) on carbon tetrachloride(CCl4)induced acute liver injury and to explore the possible mechanism.Fifty KM mice were randomly divided into five groups(n=10 in each) including blank group,model group(induced by 0.01 g/kg,0.15% CCl4 vegetable oil solution),PTE groups(0.5 g/kg and 1.0 g/kg) and positive control group(bifendate 0.15 g/kg).Alanine aminotransferase(ALT),aspartate aminotransferase(AST),malondialdehyde(MDA) content,superoxide dismutase(SOD) activity,tumor necrosis factor(TNF-α),liver wet weight index and HE staining of liver tissue pathological changes were detected in each group.Compared with blank group,the serum ALT,serum AST,liver index,MDA content and serum TNF-α increased significantly(P<0.01),SOD decreased significantly(P<0.01) and hepatic tissue pathology injured significantly(P<0.01) in model group.Compared with model group,the serum ALT decreased significantly in PTE high dose group and positive control group.The serum AST,liver index,MDA content and serum TNF-α decreased significantly(P<0.01 or P<0.05),SOD increased significantly(P<0.01) and hepatic tissue pathology relieved significantly in PTE low dose group,PTE high dose group and positive control group.In conclusion, P.puberulum water extract attenuated the CCl4-induced acute liver injury and the underlined mechanisms were,at least partly,due to their anti-oxidant actions and inhibitions of TNF-α production.
