The cellular distribution of parvalbumin immunoreactivity in the vestibular peripheral system of mouse, rat, and guinea pig was investigated by light and electron microscopy. Parvalbumin was found in all neurons of the vestibular ganglia of these species but in the sensory epithelia immunoreactivity was restricted to type I hair cells localized exclusively in the central areas. The very intense staining pattern was similar in the cristae ampullares and utricles of all three species but a faint immunoreaction was also detectable in sensory cells of peripheral areas of rat cristae. The parvalbumin-immunoreactive type I sensory cells are connected by nerve fibres of the calyx unit type which are known selectively to contain calretinin.
利用光学显微镜和电子显微镜研究了小鼠、大鼠和豚鼠前庭外周系统中小清蛋白免疫反应性的细胞分布。在这些物种的前庭神经节的所有神经元中均发现了小清蛋白，但在感觉上皮中，免疫反应性仅限于仅位于中央区域的I型毛细胞。在所有三个物种的壶腹嵴和椭圆囊中，染色模式都非常强烈，但在大鼠壶腹嵴外周区域的感觉细胞中也可检测到微弱的免疫反应。小清蛋白免疫反应性I型感觉细胞通过已知选择性含有钙视网膜蛋白的花萼单位型神经纤维相连。
