项目摘要
When heat-killed Propionibacterium acnes (P. acnes) is intravenously injected into mice and seven days later, a small amount of gram-negative lipopolysaccharide (LPS) is also intravenously injected, most of the mice die of massive necrosis. In this experimentally-induced acute hepatic failure, the adherent cells accumulated into the liver are primed by P. acnes and activated by LPS, producing the cytotoxic factor. This hepatocytotoxic factor is a protein-like substance and is relatively unstable to heat. Furthermore, in this experimentally-induced acute hepatic failure model, gomisin A, AA861, azelastine and prostaglandin <E_1> remarkably increase the survival rate of mice and improve the histological changes and necrosis of the liver cells.
小鼠静脉注射热灭活型痤疮丙酸杆菌(P.acnes),7天后静脉注射少量革兰氏阴性脂多糖(LPS),大多数小鼠死于大量坏死。在这一实验诱导的急性肝功能衰竭中,积聚在肝脏中的贴壁细胞被痤疮假单胞菌激活并被脂多糖激活,产生细胞毒因子。这种肝细胞毒性因子是一种蛋白质样物质,对热相对不稳定。此外,在实验性急性肝衰竭模型中,戈米菌素A、AA861、氮卓斯汀和前列腺素E_1及前列腺素E_1和前列腺素E_1均能显著提高小鼠的存活率,改善肝细胞的组织学变化和坏死。
