Med., 1985, 146 (1), 121-122-Respiratory resistance of guinea pigs immunized with Ascaris suum was measured over 6hr after aerosol challenge of the allergen by use of the oscillation method. These animals showed a biphasic pulmonary response to the aerosol challenge with Ascaris suum. Histological analysis of these animals revealed a narrowing of bronchial lumen, peribronchial edema and neutrophil-rich mucous in bronchial lumen at the late pulmonary response.
