The ciliated cells of Rana esculenta were experimented.Some of the medicaments e. g. 10% cocaine solution, privina, 3% Protargol and 0, 01% Janus-Green solution were applied to Rana esculenta's palatine mucosa and ciliary activity observed by indicator-movements.The ciliary beats decreased in their vigor by applying these medicaments to the pharyngeal mucosa, but after washing away these medicaments with physiological solution of salt, the ciliary activities increased in their vigor.The morphological changes of the ciliated cells, above all of cilia, were investigated by an electron microscope.After applying medicaments to the palatine mucosa, cilia showed two types of change.The one is as follows, that the peripheral sheath of cilia was observed to be extended from the level of basal-plate in longitudinal section and the length of cilia was measured not long but the breadth was wide, so that the axial filaments were bent within the space where is surrounded by peripheral sheath, therefore in transverse section, cilia were observed as if they were joined with each other. In this case, no substances were found in the space between the axial filaments and peripheral sheath.The other type, the cell membrane which located between the neighbouring cilia in the same cell was pushed out for the top level of cilia and this variety of cell membrane was progressed gradually, finally it reached to the top. And neighbouring two cilia seemed to be joined virtually. In this type, the space between the axial filaments and peripheral sheath was fulled with the matter which looks like ground substance of the cell.
