Abstract
1) In the two patients of conjac asthma, on which I reported in the previous paper with regard to scratch test, ocular test (conjunctival test) and Prausnitz-Küstner test, etc, I succeeded to induce asthmatic paroxysm with the conjac flying-powder or its extract.
2) Asthmatic paroxysm could not be induced with the conjac flying-powder in any of eleven patients of general asthma. Nor could it be induced in either of the two patients of conjac asthma by the inhalation of powdered root of Colocasia antiquorum and spinach, etc.
3) The evident paroxysm could not be induced in the two patients by subcutaneous injection of histamine or mecholin (β-methyl-acetylcholine), but it could be induced in both by the inhalation of acetylcholine, and in case 2 by the inhalation of histamine.
4) Analysis for the allergen by the inhalation test revealed that it was found in the protein fraction
5) Administration of cortisone and ACTH could not prevent the development of paroxysm.
From these results, conjac asthma was considered to be allergic asthma due to the allegen of the conjac flying-powder
