硫化氢(H2S)是一种带有臭鸡蛋味的有毒气体,以其毒性而闻名。20世纪90年代中期,科学家证明人体内源性硫化氢可作为一种神经活性物质而存在。越来越多的研究证明,H2S是继一氧化氮和一氧化碳后发现的一种新型气体信号分子。有关H2S与相关疾病的文献分析发现,H2S广泛参与机体多种生理、病理过程,且在许多器官和系统中起着保护作用。近来研究发现,硫化氢对烧伤后脏器功能的保护产生积极作用。 Hydrogen sulfide (H2S) is a poisonous gas with rotten egg flavor, known for its toxicity. In the mid-1990s, scientists demonstrated that human endogenous hydrogen sulfide can exist as a neuroactive substance. More and more researches prove that H2S is a new type of gas signal molecule discovered after nitric oxide and carbon monoxide. Literature analysis of H2S and related diseases found that H2S is widely involved in many physiological and pathological processes of the body and plays a protective role in many organs and systems. Recent studies have found that hydrogen sulfide has a positive effect on the protection of organ function after burn.
