提到一氧化氮(NO),人们的第一印象往往是汽车尾气、工业废气等空气污染物,谁能想到它可以在体内产生化学作用,为人类健康带来福祉呢?然而,当1998年三位科学家由于发现一氧化氮作为人体中一种重要的信号分子而获得诺贝尔医学奖之后,人们才逐渐相信,一氧化氮是身体中对健康最重要的化学分子之一。人的机体内有很多信号系统,它们可以调节全身的血管网络,将含氧血送到组织和器官当中,让人体血压保持在适当水平。人体内生成的一氧化氧自由基,可以穿透任何细胞,到达任何组织,使信息从人体某一部分,传至其他部分,行使着传输信号的功能。这样使血管扩
When it comes to nitric oxide (NO), people’s first impression is often air pollutants such as automobile exhaust and industrial exhaust. Who can think that it can produce chemical effects in the body and bring benefits to human health? However, when the year 1998 The discovery of nitric oxide as an important signaling molecule in the human body by three scientists who won the Nobel Prize in Medicine led to the belief that nitric oxide is one of the most health-conscious chemical molecules in the body. There are many signaling systems in the human body that regulate the body’s vascular network and deliver oxygenated blood to tissues and organs, keeping the body’s blood pressure at an appropriate level. The oxygen free radicals generated in the human body can penetrate any cell, reach any tissue, and transmit information from one part of the body to the other part. This makes vasodilation
