Abstract

Ethane has been identified and quantitated in air exhaled by mice following intraperitoneal injection of 20, 40, or 200 mg of Escherichia coli O111:B4 lipopolysaccharide (LPS) per kg. Significant increases in ethane concentration occurred within 1 to 5 h after LPS administration. In addition, increased concentrations of malondialdehyde were found in crude homogenates of livers obtained from mice 16 h after administration of 20 mg of LPS per kg. These results suggest that lipid peroxidation may be an important mechanism responsible for LPS toxicity.

摘要

在给小鼠腹腔注射每千克20、40或200毫克大肠杆菌O111:B4脂多糖(LPS)后,已在小鼠呼出的空气中鉴定并定量了乙烷。LPS给药后1至5小时内,乙烷浓度显著增加。此外,在给每千克体重20毫克LPS的小鼠给药16小时后,从其肝脏的粗匀浆中发现丙二醛浓度升高。这些结果表明,脂质过氧化可能是LPS毒性的一个重要机制。
