哮喘患者在运动时会出现支气管痉挛和运动后有支气管狭窄的现象。某些有哮喘倾向的人,运动是主要的甚至是唯一的起病因素。现在证明部分健康人在作脚踏研磨机运动中也出现呼气流量的减少,提示健康人和哮喘患者对运动后气流量的减少并无本质的区别,而仅是量的多少而巳。已知DSCG(色甘酸二钠)对哮喘患者运动后支气管收缩有显著的保护作用,而它对正常人是否亦有类似作用尚未明确,作者等乃作如下的研究。方法:选择无呼吸道疾病、胸部听诊正常且无家族过敏倾向、平均年龄为23.5岁的健康男青年26名,
Asthma patients have bronchospasm during exercise and bronchoconstriction after exercise. Some people with asthma tendency, exercise is the main or even the only contributing factor. Now it turns out that some healthy people also experience a reduction in expiratory flow during pedal mill exercise, suggesting that there is no essential difference between healthy and asthmatic patients in their reduction in post-exercise airflow, but just how much. DSCG (disodium cromoglycate) is known to have a significant protective effect on bronchoconstriction after exercise in asthmatics and it is unclear whether it has a similar effect on normal people. The authors are as follows. Methods: Choose no respiratory disease, normal chest auscultation and no family allergy tendency, the average age of 23.5 healthy young men 26,
