石綿曝露者における気道過敏性に関する研究 : 第二報 他覚症状の検討

Abstract

To clarify airway hyper-responsiveness caused by asbestos fiber inhalation, methacholine inhalation test (Astograph method) was performed for 45 asbestos workers. It was revealed that airway hyper-responsiveness existed in about half of asbestos workers, but there was no relationship between duration of asbestos exposure and the ratio of developrent of airway hyper-responsiveness. Airway rcactivity, a part of airway hyper-responsiveness, had a relationship with dura- tion of asbestos exposure. And airway sensitivity, another part of airway hyper-responsive- ness, had a relationship with chest X-P findings. But in this study, the primary factor of the airway hyper-responsiveness could not be determined.
