大鼠运动行为的自动化检测与评估(英文)

Automatic detection and evaluation of motor behavior in rats

目的:探讨大鼠运动行为的自动化检测与评估方法。方法:利用计算机自动化技术对大鼠运动行为进行记录,并对记录数据进行统计整理,找出具有代表意义重复性高的评估其运动行为特征的指标。结果:通过对大鼠各运动速率百分比加权求和得出实验动物运动水平值(M)可以反映其整体运动行为状况,根据运动速率可将大鼠在特定时间段内的活动区分为4种类型,实验动物入陌生环境最初25min4种运动类型所占份额的百分比数值有较好的重复性。结论:在大坪医院野战外科研究所五室自行研制的实验动物运动行为自动化检测系统中,运动水平值(M)和最初25min4种运动类型所占百分比值可作为衡量大鼠运动特征的重要指标。

AIM:To investigate the methods for automatically detecting and evaluating the motor behavior in rats. METHODS:Motor behavior of rats was recorded by computer automatic technique.Data recorded were gone through statistical analysis to find the index that was representative and with high repetition to evaluate the motor behavioral characteristics. RESULTS:The motor value(M) obtained from the weighted sum of different speed rate percentage in experimental animals could reflect the integral motor behavioral conditions.The activities of rat in a special period of time could be classified into 4 types on the basis of motor speed rate.There was a preferable repetition of the percentage value of the first 25 minutes of 4 motor types after animals being put into a strange environment. CONCLUSION:M and the percentage vale of first 25 minutes of 4 motor types can be used as an important index in measuring motor characteristic in rats in the automatic detective system for motor behaviors in experimental animals developed by Military Surgery Institute of Daping Hospital.
