作者用反复壶腹测量法的旋转(最终旋转速度180°/秒),刺激24～72小时后,比较豚鼠壶腹向心流动侧和离心流动侧,壶腹侧嵴发生的机能和形态学改变。结果,反复旋转后,所有动物均出现Hood和Pfaltz(1954)描述的反应性减退现象,24小时后,眼震跳动的总数降至最初阶段的45%,72小时后,降至29%。眼震持续期出现相同的降低率;所有动物在壶腹向心流动侧出现“半规管轻瘫”,刺激24小时后,壶腹向心侧内耳的冷热反应只有离心侧的80%,72小时后变成64%。旋转后眼震容易减退的动物,壶腹向心流动侧的冷热反应有较大的降低。扫描电镜下,刺
The authors used repeated ampulla measurements of rotation (final rotation speed of 180 ° / sec) to compare the functional and morphological changes in the ampulla crest of guinea pig ampulla after centriole flow and centrifuge flow, 24-72 hours after stimulation . As a result, all animals experienced hyporesponsiveness as described by Hood and Pfaltz (1954) after repeated rotations. After 24 hours, the total number of nystagmus dropped to 45% of the initial phase and decreased to 29% after 72 hours. Nystagmus duration of the same rate of decrease; all animals in the ampulla flow to the side of the “semicircular canal paresis”, 24 hours after stimulation, ampulla to the inner ear of the hot and cold reactions only centrifuge 80%, 72 hours After becoming 64%. After rotating the nystagmus easy to reduce the animal, ampulla to the heart side of the hot and cold reaction has a greater reduction. Under scanning electron microscope, thorn
