H2S是一种公认的毒性气体,但最近发现其是神经、心血管等系统功能调节的新型气体信号分子。BlackstoneE等在Science杂志上报道:将小鼠暴露于80ppm(80mg/m3)的H2S中,五分钟小鼠的氧消耗下降50%,CO2的排出量下降60%,暴露6小时,代谢率下降90%,中心体温下降到比周围环境温度高2℃。 H2S is a recognized toxic gas, but has recently been found to be a novel gas signaling molecule that regulates the function of the nervous and cardiovascular systems. Blackstone et al reported in Science that exposure of mice to 80 ppm (80 mg / m3) of H2S resulted in a 50% reduction in oxygen consumption and a 60% reduction in CO2 emissions in five minutes, a six-hour exposure and a 90% reduction in metabolic rate %, The central body temperature dropped to 2 ℃ above the ambient temperature.
