The developing electrolytes concentrations of inner ear fluids in guinea pigs
Abstract
Cochlear endolymph, scala tympani perilymph, and scala vestibuli perilymph were collected from fetal, neonatal, and mature guinea pigs. The concentrations of Na and K in these fluids were then assessed using a microflame photometer. The electrolyte composition in the endolymph was already characterized by a high concentration of K and a low concentration of Na by the 49th day of gestation.
