This study aims to investigate the protective effect and mechanism of sublow temperature on d-GalNLPS-induced acute liver failure in rats.Healthy male C57BL/6J rats were randomly divided into normal control group, model group and sublow temperature treatment group. The model group and the sublow temperature treatment group were induced acute liver failure with d-GalNLPS, while the sublow temperature treatment group was subjected to 7°C low temperature treatment at 0.5h, 1h, 2h and 4h after d-GalNLPS injection. The survival rate, hepatic histopathology, liver function and liver cell damage indicators of rats were observed.Expected results: The survival rate of rats in the sublow temperature treatment group was higher than that in the model group, the hepatic histopathology was milder, the liver function recovered faster, and the liver cell damage indicators were lower. The mechanism analysis showed that sublow 精品文档---下载后可任意编辑temperature protected the liver from d-GalNLPS-induced acute liver failure by inhibiting inflammatory response and reducing oxidative stress.Keywords: sublow temperature; d-GalNLPS; acute liver failure; protective effect; inflammatory response; oxidative stress.
