The influence of artificially generated atmospheric ions is studied in 15 patients with bronchial asthma. A slight but significant (at 5% level) improvement in the lung function was demonstrated in nine patients during positive as well as negative ion exposure, but the patients' subjective votings of the air quality did not show any changes due to ion exposure. No change in the histamine threshold of the airways in six patients with bronchial asthma was demonstrated during exposure to ions. Further controlled studies with electro-aerosols are needed.
对15名支气管哮喘患者进行了人工产生的大气离子影响的研究。在9名患者中，无论是在正离子还是负离子暴露期间，肺功能均有轻微但显著（5%水平）的改善，但患者对空气质量的主观投票并未显示出因离子暴露而有任何变化。6名支气管哮喘患者在离子暴露期间，气道组胺阈值未显示变化。需要进一步用电气溶胶进行对照研究。
