创伤、中毒、血管功能障碍、老年性改变、先天性异常等致病因素均可使囊斑的终器发生结构改变,包括感觉上皮、胶状膜和位觉砂。按照内淋巴流动和作用力的方向。脱落的位觉砂可到达内淋巴系统的任何部位。作者对鼠猴脱落的位觉砂分布情况进行了研究。目的是查明:①脱落的位觉砂分布部位;②内耳的清除机能如何处理这些自身的碎片。方法:对曾暴露在强直线加速度下(额枕方向)鼠猴的13对颞骨(以下简称高G组)和链霉素中毒的鼠猴5对颞骨(以下简称链霉素组)进行研究。所有颞骨标本都是经心脏作Heidenhain-S usa法灌注后取出,按标准火棉胶切片步
Traumatic injury, poisoning, vascular dysfunction, senile changes, congenital abnormalities and other causative factors can make structural changes in the end of the capsule plaque, including the sensory epithelium, gel-like membrane and sensory sand. Follow the direction of endolymphatic flow and force. Exfoliated bit of sand can reach any part of the endolymphatic system. The authors studied the distribution of biting sand shed by rats. The purpose is to identify: ① exfoliated biting sand distribution site; ② clear function of the inner ear to deal with these own fragments. METHODS: Thirteen pairs of temporal bone (hereinafter referred to as “high G” group) and streptomycin-poisoned rhesus monkey 5 exposed to rodent tetanus under intense linear acceleration (frontal occipital direction) were studied on temporal bone (hereinafter referred to as streptomycin group). All temporal bone specimens were removed by perfusion of the heart for Heidenhain-S usa perfusion, according to standard collodion slices
