热应激条件下机体发生氧化应激的机制

摘要

热应激是指机体在高温条件下对热暴露所做出的非特异性生理反应的总和.有研究表明热应激会引起机体氧化还原平衡紊乱,发生氧化应激,损伤细胞和组织,从而影响机体的生长发育及健康状况.热应激一直都是国内外研究的热点,随着全球气温的上升,热应激问题将会更加突出,本文就热应激条件下氧化应激发生的机制作一综述,以期为后续的相关研究提供参考.%Heat stress is the nonspecific physiological responses of body to heat exposure at high ambient temperature.A large number of studies show that heat stress can cause the body redox unbalance,which results in oxidative stress,damaged cells and tissues,and affecting growth and development as well as health.This research on heat stress has always been a hot research field both at home and abroad.With the increase of global temperature,the problem of heat stress will become more prominent.In this paper,the mechanism of oxidative stress under heat stress is reviewed to provide a reference for the following study.
