Disc Electrophoretic Studies of Human Perilymph and Endolymph

Abstract

Results are reported on micro disc electrophoresis performed on 30 perilymph and 30 utricular endolymph specimens. Contamination with dissolved hemoglobin affects both fluids: four almost pure fluid samples show that the cochlear fluid proteins are made up of strong albumin and two weak prealbumin bands. While LDH isoenzymes 4 and 5 appear more frequently in perilymph than in endolymph, the total concentration of LDH seems to be higher in endolymph than in perilymph, both values being clearly higher than those in serum or CSF.
