急性高原适应不全症(AMS)是机体初入高原产生的急性缺氧反应或疾病〔1〕。近年研究表明,在缺氧时机体释放和合成β-内啡肽(β-EP)增加,并参与病理、生理过程〔2〕,但目前对β-EP与AMS的关系报道甚少。作者对急进高原者血浆β-EP变化进行了系统观察,以探讨β-EP对AMS的影响及意 Acute altitude sickness syndrome (AMS) is the body into the plateau of acute hypoxia or disease [1]. In recent years, studies have shown that the body release and synthesis of β-endorphin (β-EP) increase during hypoxia and participate in pathological and physiological processes [2], but little is known about the relationship between β-EP and AMS. The authors systematically observed the plasma β-EP changes in acute plateau to explore the effect of β-EP on AMS
