在技术高速发展的现代,物理因素对机体的影响不断增长。利用高速运载工具的职工和军职人员常受线性或离心加速度的作用导致前庭耳蜗功能紊乱。本文旨在研究具有慢性化脓性中耳炎的豚鼠和家兔在加速度作用下耳迷路感受器的超微结构改变。离心加速度用离心机进行,动物固定两种体位;使离心力能对椭圆囊的耳石膜施加压缩(+Gx)和牵拉(-Gx)作用。超负载刺激共做10次,持续5秒。结束后经1小时,6～12小时,24小时和两周各处死2只豚鼠和2只家兔。另外2只豚鼠1
In the rapid development of technology, the influence of physical factors on the body is growing. Staff and military personnel who utilize high-speed vehicles are often subject to linear or centrifugal acceleration resulting in dysfunctional vestibulocochlea. This article aims to study the ultrastructural changes of the otolareceptors in guinea pigs and rabbits with chronic suppurative otitis media under acceleration. Centrifugal acceleration was performed with a centrifuge, animals were fixed in two positions; centrifugal force can exert compression (+ Gx) and pull (-Gx) effect on the otolith membrane of the ellipsoid capsule. Overload stimulation to do a total of 10 times, for 5 seconds. After the end of 1 hour, 6 to 12 hours, 24 hours and two weeks each killed two guinea pigs and two rabbits. 2 other guinea pigs
