Abstract

|
|
The effect of rotatory stimulation and vibration on retention ti me in mouse was investigated, and the following results were obtained, 1) After mild rotatory stimulation(45 rpm for 5 min.). the retention time of mouse was recorded as 56.9±22.2sec., and after strong rotatory stimulation(78 rpm for 10 min.). the retention time was 86.5 ± 23.06sec.,so,retention impairment was produced by rotatory stimulation. 2) When experimenting the passive avoidance learning and retention function, after electrical shock was applied in mouse,retention time of control group was 508.3 ±50.9 sec? and rotation group was 578.8-F21.2 sec., single rotatory stimulation was not having any effect on mouse short term memory loss.
3) After scopolamine intraperitoneal injection, rest group showed 20.86:L4..55 sec. retention time,and retention time of rotatory group was 27.43:h6.09 sec. The retention impairment of mouse produced by rotation was somewhat improved significantly by scopolamine injection. 4), After 10 min. rest, the retention time was 24.254-6.74 sec. but after electrical shock was applied in mouse, the retention time of control group was 582.5-h.17.5 sec., and vibration group was decreased to. 446.4±55 ,sec. So 10 mina whole body vibration effected on mouse short term memory loss.
