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。
Objective: To explore the automatic detection and evaluation of motor behavior in rats. Methods: The motor behavior of rats was recorded by using computer automation technology, and the recorded data were statistically sorted out to find out the indexes with high repetitiveness and representativeness to evaluate their motor characteristics. Results: By weighted summation of the percentage of rats’ exercise rate, the experimental animals’ exercise level (M) can reflect the overall exercise behavior. According to the exercise rate, the rats’ activities during the specific time period can be divided into four types , Experimental animals into unfamiliar environment, the first 25min 4 types of exercise share of the percentage value is better repeatability. CONCLUSION: The value of exercise level (M) and the percentage of the 4 kinds of exercise types in the first 25 minutes in the automatic test system of experimental animals developed by five laboratories of the Research Institute of Field Surgery, Daping Hospital can be used as an important index to measure the movement characteristics of rats.
