在复习文献的基础上,作者对鸽子的基底膜运动进行研究。用体重360～570g的家鸽,肌注硫酸阿托品0.2ml后,以硫喷土钠麻醉,在测试前用人工呼吸(4％CO_2及96％O_2)及氯化二丙烯基正箭毒碱使肌肉麻痹,控制体温并作心电图监护。在圆窗缘处用电极记录复合动怍电位频率阈曲线以监测内耳的生理学状态。从腹侧暴露内耳,在底区打开鼓阶暴露基底膜,去除外淋巴,放入Mssbauer放射性源液,使鼓阶可被再充满或在有必要时用林格氏液补足之。实验之末测毫从基底膜底部终端以放射原中心的距离。用与Sellick等(1982)所用相似的Mssbauer技术测试基
Based on the review of the literature, the authors studied the motility of the basement membrane of pigeons. Domestic pigeons weighing 360-570g were intramuscularly injected with 0.2ml of atropine sulphate and anesthetized with sodium sulfur spray soil. Before the test, artificial pigeons (4% CO 2 and 96% O 2) and dicaproic rhinoceros Muscle paralysis, temperature control and ECG monitoring. The composite dynamic 怍 potential frequency threshold curve was recorded at the circular window edge with electrodes to monitor the physiological condition of the inner ear. The inner ear is exposed from the ventral side, the basal membrane is exposed by opening the scala tympani in the bottom zone, the perilymph is removed, the Mssbauer radioactive source solution is placed so that the scala tympani can be refilled or, if necessary, complemented with Ringer’s solution. At the end of the experiment measure the distance from the bottom of the basement membrane to the center of the original radiate. Mssbauer technology test bases similar to those used by Sellick et al. (1982) were used
