硫化氢(H2S)作为一种有毒气体,人类认识和研究其作用已有300多年历史。直到上世纪90年代中期,人们发现包括人类在内的哺乳动物可代谢生成气体分子H2S,对神经系统特别是海马的功能具有调节作用,并可以调节消化道和血管平滑肌的张力,而其作用特点有别于另外两种气体信号分子NO及C Hydrogen sulfide (H2S) as a toxic gas, human understanding and research its role has been 300 years of history. Until the mid 90s of last century, it was found that mammals, including humans, can be metabolized to produce gas molecules H2S, regulating the function of the nervous system, especially the hippocampus, and can regulate the digestive tract and vascular smooth muscle tension, and its role in the characteristics Different from the other two gas signaling molecules NO and C.
