Kinetic and pharmacological characteristics of Ca2+ fluxes across the saccular epithelium of trout were studied using a perfused isolated inner ear. Ca-45(2+) influx from the Ringer solution to the endolymph was 3-4 nmoles h(-1) mu(-1) endolymph, which corresponds to a global turnover rate of the en...
