中暑研究进展

中暑是严重影响生命健康和劳动效率的一种夏季常见病 ,国内外学者通过动物实验不断研究中暑发病机制。 (1)热适应中热应激蛋白发挥十分重要的作用 ,但热适应是有一定限度的 ,超过这个限度就会引起热损伤。 (2 )高热使IL - 1、肾上腺素能受体等发生相应改变 ,使人体耐热 ,同时过热会使细胞膜、细胞器、酶类受损 ,导致细胞受损甚至凋亡 ,组织功能障碍。 (3)高热作用于低位脑干 ,使呼吸循环中枢病变 ,导致呼吸循环衰竭。 (4)神经系统出现损伤并出现神经精神症状是热射病的关键指征。

Research advancement of heat- stroke

Heat-stroke is a common disease in summer which influences health and efficiency of labour seriously.Scholars at home and abroad keep on studying the cause of the disease by animal experiments.(1)heat stress proteins play an important role in heat acclimatization,but heat acclimatization has its limit,beyond this limit heat hurt will occur.(2)hyperthermia result in corresponding alterations of IL-1,adrenergic receptor etc,which make the body increase its survivability to heat,however hyperthermia hurt cell membrane,organelle,enzyme,which make cells hurt or died and impair the tissue function.(3)hyperthermia effect truncus encephalicus,disorder the functions of respiration center and circulatory center,which result in respiration and circulatory failure.(4)The key symptoms of heat-stroke are the harm to nervous system and nervous or phrenic symptom.
