Inner ear fluids of guinea pigs and cats were analyzed for sodium, potassium, chloride, glucose, and total protein to determine species differences in chemical compositions. In the scala vestibuli perilymph and scala tympani perilymph, sodium potassium, and choride levels in the guinea pig were lower than in the cat. The protein levels in the scala vestibuli perilymph and scala tympani perilymph of the guinea pig were lower than those of the cat. The glucose levels in the guinea pig were higher in the scala vestibuli perilymph and scala tympani perilymph, as compared to findings in the cat. Regarding the utricular endolymph, there were significant differences between guinea pigs and cats in sodium and potassium concentrations; the concentration in the former being higher in sodium and lower in potassium. These findings are pertinent for the phylogenetic studies on inner ear fluid biochemistry.
分析豚鼠和猫的内耳液体中的钠、钾、氯、葡萄糖和总蛋白，以确定化学成分的物种差异。在豚鼠的前庭阶外淋巴和鼓阶外淋巴中，钠、钾和氯的水平低于猫。豚鼠前庭阶外淋巴和鼓阶外淋巴中的蛋白质水平低于猫。与猫的研究结果相比，豚鼠前庭阶外淋巴和鼓阶外淋巴中的葡萄糖水平更高。关于椭圆囊内淋巴，豚鼠和猫在钠和钾浓度上存在显著差异；前者的钠浓度较高，钾浓度较低。这些发现对于内耳液体生物化学的系统发育研究具有重要意义。
