以往认为,高原世居者即使迁居至海平面其颈动脉体(CB)敏感性仍然低于世居海平面者。本实验用两种技术在海平面比较了两组医学生的CB功能。受试者6人,19～24岁,均生长在海拔3000米以上的安第斯山区,居住海平1～3年,其间每年返回高原约1～2月,对照组6人,20～24岁,生长居住海平,两组均男女各半,不吸烟,常规检查无异常,肺活 In the past, the highland natives were still below the native sea level with their carotid body (CB) sensitivity even after moving to sea level. The experiment compared the CB function of two groups of medical students at sea level using two techniques. Subjects 6, 19 to 24 years of age, were growing in the Andes at an altitude of 3000 meters above sea level, living sea level for 1 to 3 years, during which each return to the plateau about January to February, the control group of 6, 20 to 24 years old, growth Living sea level, both men and women in each group were half, no smoking, no abnormalities routine examination, lung live
