近年来国外对内皮素(ｅｎｄｏｔｈｅｌｉｎ,ＥＴ)在胃肠损伤中的机制、病理生理改变进行了大量的动物实验研究[2-5]。结果表明:ＥＴ对胃肠道血管平滑肌的调整及在胃肠粘膜损伤中起着重要作用。但ＥＴ在人胃肠疾病中的作用尚缺乏进一步研究。我们利用本地冬泳人员,设计进行了0℃
In recent years, many studies on the mechanisms and pathophysiological changes of endothelin (ET) in gastrointestinal injury have been carried out in foreign countries [2-5]. The results showed that: ET plays an important role in the regulation of gastrointestinal smooth muscle and gastrointestinal mucosal injury. However, the role of ET in human gastrointestinal diseases is still lack of further study. We used the local winter swimming staff, the design was carried out at 0 ℃
