Effects of histamine and antihistaminics on the cilia in isolated oral mucous membrane of frog was studied and following results were obtained.
1. Except anergen, histamine, benadryl and pyribenzamine showed a potent acceleration of ciliary movement, while anergen showed no effect on this movement. The acceleration of ciliary movement by histamine were entirely abolished by these three antihistaminics.
2. Atropine, ephedrine and regitine showed neither any effect on ciliary movement, nor antagonism on the accelerating effect of histamine.
