[The results of the dynamic observation of bronchial hyperreactivity in risk-group subjects and in bronchial asthma patients. Some corrective procedures].

The following bronchial provocation tests were carried out: 310 with acetylcholine, 216 with submaximal physical exercise, 246 with cold air inhalation, and 103 with aspirin in healthy subjects, relatives of bronchial asthma patients, in patients with preasthma and asthma in a stage of exacerbation abatement or remission. Based on the data obtained the authors show nonspecific hyperreactivity of the bronchi in healthy relatives of bronchial asthma patients, heterogeneity and a high incidence of responses to acetylcholine, cold air and physical exercise, augmentation of the reaction intensity to different stimuli in all asthma patients. The follow-up of bronchial hyperreactivity discovered its progression in the absence of the treatment and the lowering of its intensity as a result of the treatment with calcium antagonists, magnesium sulfate, punctate massage, sublaminal physical exercise, ultraviolet radiation of autologous blood, specific desensitization with aspirin.
