研究表明血清 K~+可影响呼吸道平滑肌的反应性,并与运动性哮喘(EIA)的发病机理有关。正常人血清(K~+)随着运动强度增加而呈线性增加,Haas的研究表明,哮喘患者在运动后血(K~+)比正常人高。为了进一步证实,作者观察32例哮喘患者(其中12例为 EIA)血清K~+对运动的反应,并用7例健康受试者作对照。受检者在运动前至少停药12小时,全部患者均无症状和气道阻塞,且体检和胸片无任何异常。健康人 FEV_(1.0)/VC 和 FEV_(1.0)(%)平均值分别为80.3和101.4,病人组分别为78.4和102.5。所有受试者 Studies have shown that serum K ~ + can affect the reactivity of airway smooth muscle and is related to the pathogenesis of exercise-induced asthma (EIA). The normal serum (K ~ +) increased linearly with exercise intensity. Haas’ study showed that blood (K ~ +) in asthma patients was higher than that in normal subjects after exercise. To further confirm, the authors observed the response of serum K + to exercise in 32 asthmatic patients (12 of whom were EIA) and compared them to 7 healthy subjects. Subjects at least 12 hours before exercise withdrawal, all patients were asymptomatic and airway obstruction, and physical examination and chest X-ray without any abnormalities. The average FEV_ (1.0) / VC and FEV_ (1.0) (%) of healthy people were 80.3 and 101.4 respectively, and the patients were 78.4 and 102.5 respectively. All subjects
