[Action of hyperoxia on the total electrical activity of the olfactory epithelium of the frog].
Olfactory mucosa of the frog was stimulated with odours of amylacetat , butanol, alcohol, naphthalene, acetic acid in air and oxygen media under normal and high oxygen pressure (0.2 MPa and 0.7 MPa). The electroolfactogram (EOG) amplitude was higher in oxygen due, probably, to the olfactory mucosa oxygen saturation on concentration gradient as well as to the activation of processes related to the EOG generation. 0.2 MPa pressure as well as 0.7 MPa pressure applied for 60 min decreased the EOG amplitude.
