偏心旋转刺激下大鼠前庭核c-fos表达的观察

目的 观察偏心旋转刺激下前庭核早期即刻基因Ｃ－ｆｏｓ的表达特征和抗运动病药物对这种表达的影响。方法 取ＳＤ大鼠１９只分为对照组，旋转组、药物组三组。庄园２组用偏心旋转刺激方式刺激６０ｍｉｎ；药物组在偏心旋转刺激前４５ｍｉｎ腹腔注射抗运动病药物盐酸扁桃桥哌酯（ＰＡＰＭ），对照组不进行旋转刺激。用免疫组化法和图象分析技术对大鼠脑干前庭神经ｆｏｓ蛋白含量变化进行定量、定位、测定。结果 偏心旋转刺激。用免

c-fos Expression in Rat's Vestibular Nucleus Under Eccentric Rotational Stimulation

Objective: To investigate the c-fos expression in rat's vestibular nucleus under eccentric rotational stimulation and the effects of anti-motion sickness drug (PAPM) on this expression. Method: 19 SD rats were divided into three groups: A, B and C. A received as control. B was stimulated by eccentric rotation for 60 minutes. C received injection of PAPM through cavun abdominis 45 min before eccentric rotation. Immunohistochemical method and computerized image analysis were used to map locations of c-fos protein appeared in four vestibular nucleus and to count the masculine cells. Result: c-fos protein appeared in four vestibular nucleus areas after stimulation, and PAPM had no influence on this expression. Conclusion: It suggests that c-fos expression in vestibular nucleus is one of the important way in which vestibular nervous system reacts to outside stimulation and this expression has no direct relationship with the generation and development of motion sickness.
