The diffusional water permeability of the endolymph-perilymph barrier was determined in guinea pigs by perfusing the perilymphatic space with tritiated water and measuring the uptake of tritiated water into the endolymph. Assuming that the volume flow across the endolymph-perilymph barrier is negligible for short periods of perfusion, the water permeability of the barrier is approximately 130 times greater than its permeability to K+ in normal guinea pigs.
通过向豚鼠的外淋巴间隙灌注氚标记水并测量氚标记水进入内淋巴的摄取量，测定了内淋巴-外淋巴屏障的扩散水渗透性。假设在短时间灌注过程中，跨内淋巴-外淋巴屏障的体积流量可忽略不计，在正常豚鼠中，该屏障的水渗透性大约比其对K+的渗透性大130倍。
