The present study is to culture otocyst cells in fetal, cochlear sensory epithelial cells of neonatal and mature respectively in vitro with refinement of culture media and techniques. Immunocytochemistry and Bromodeoxyuridine labeling are used to detect properties and mitotic status of cultured cells.

The central integrative part of the baroreflex receives afferent information not only from the sino-aortic baroreceptors, but also from various other sources. The present study was to investigate the effect of somatic nerve stimulation on baro-reflex. The exoeriment was performed in α-chloralose-urethane anesthetized rabbits. Intrasi- nusal pressure -mean arterial pressure res- ponse curves were constructed.

在自然状态下，各种传入冲动汇集中枢，很多传入冲动都可影响压力感受性反射，使压力感受性反射受到调制而发生重新调定·本实验旨在观察刺激躯体神经对压力感受性反射的重调定并分析其机制·实验在α-氯醛糖和氨基甲酸乙酯混合麻醉的家兔上进行，利用颈动脉窦灌流技术测量不同窦内压时体循环平均动脉压的水平，并画出窦内压-体循环平均动脉压反应曲线。
