The article is devoted to the study of the function of the lungs in pollen bronchial asthma. The authors used Tiffeneaus test, determined compliance test and applied pneumotachometry. A total of 30 patients with pollen asthma with an allergy to pollen of cereal grass, trees and wormwood were examined. Investigations were made during the period of remission and post-vaccinal inhalation test with a specific pollen allergen. Results of investigations showed that in pollen bronchial asthma and during remission the function of external respiration was found to be lowered. Sensitivity of the broncho-pulmonary apparatus to acetylcholine in pollen asthma fluctuated from 0.001 to 1 and corresponded to the severity of the disease. Threshold doses of a specific pollen allergen was from 11024 to the units of protein nitrogen 10 000 in 1 ml. The authors assume that normal indices of the external respiration function during remission of pollen bronchial asthma with a protracted course are characteristic of the atopic form of bronchial asthma as distinct to an infectious-allergic form.
