Under sodium pentrobarbital anesthesia (20-30 mg/kg, i.p.), normal guinea pigs received an intravenous injection of glycerol (1.0 ml/kg). Serum, cerebrospinal fluids (CSF) and inner ear fluids were collected from the scala tympani perilymph, scala vestibuli perilymph and the scala media endolymph. The sodium and potassium concentrations were assessed using microflame photometry. Increases in sodium concentration were found in the CSF and the scala tympani perilymph; no significant changes were observed in the serum, scala vestibuli perilymph or the scala media endolymph. These sodium increases were considered to be a result of the dehydration process caused by the osmotic agent glycerol. Increases in potassium concentration were found only in the scala vestibuli perilymph.
在戊巴比妥钠麻醉（20 - 30毫克/千克，腹腔注射）下，正常豚鼠接受甘油静脉注射（1.0毫升/千克）。从鼓阶外淋巴、前庭阶外淋巴和中阶内淋巴收集血清、脑脊液（CSF）和内耳液。使用微火焰光度法评估钠和钾的浓度。在脑脊液和鼓阶外淋巴中发现钠浓度升高；血清、前庭阶外淋巴或中阶内淋巴中未观察到显著变化。这些钠的升高被认为是渗透剂甘油引起的脱水过程的结果。仅在前庭阶外淋巴中发现钾浓度升高。
