摘要

The present invention relates to a method of preparing bronchial hypersensitive or hyposensitive guinea pigs by selective breeding on the basis of bronchial sensitivity to inhalant chemicals inducing bronchoconstriction. The hypersensitive guinea pigs of the present invention are extremely useful as model animals for the study of bronchial asthma and allergic rhinitis and for the evaluation of efficacy of-antiasthmatics and antiallergic substances.
