Objective To investigate the protective action of ethyl pyruvate on liver injury induced by rifampicin in mice and its possible mechanism. Methods Twenty-four male C57 BL/6 mice were randomly divided into normal group,model group(rifampicin,200 mg·kg~(-1)·d~(-1)) and ethyl pyruvate group(rifampicin,200 mg·kg~(-1)·d~(-1)+ethyl pyruvate,40 mg·kg~(-1)·d~(-1)). Each group consisted of eight animals. The mice were sacrificed on day 7. The serum levels of alanine aminotransferase( ALT),total bilirubin( TBIL),dire...
利福平(rifampicin,RFP)是世界卫生组织推荐的一线抗结核药物之一。利福平单独或者与其他抗结核药物联合使用时,都可引起不同程度的肝损伤,但具体的发病机制仍未明确。高迁移率族蛋白BI(high mob-ility group box-1,HMGB1)是近年研究发现的一种强大的致炎细胞因子,可能与异烟肼
