Two kinds of drugs for prevention and remedy of Ammonia dermatitis, Permachem and Diapp, both on the market, were examined as to the germicidal and antibacterial power over Brevibacterium ammoniagenes, Proteus vulgaris and Escherichia coli. Either chemical was tested in its action to bacteria, and its function according to the various concentration. 1. Permachem and the processed cloth and Diapp and the processed cloth were bactericidal to Br. ammomagenes and Es. coli in the concentration indicated by the makers (15min action), particularly active to the former even in the solution 8 times thinner than the indication. Either drug was not active to Proteus vulgaris in the concentration 0.2^ weaker. It was impossible to inhibit the growth of Proteus vulgaris even in the concentration four times stronger than the indication. Therefore it was assumed that only the inhibition of Br. ammoniagenes is not enough for the prevention of Ammonia dermatitis. 2. Permachem processed cloth was germicidal even after the third washing in water 40℃ for 10 min. When the processed cloth was soaked in soap water for 10 min and was rinsed, the function of the drug was lost. Therefore an ordinary way of soap washing spoils the action of the chemical. Attention should be paid not to trust too much on the action of the drugs.
