目的:观察空间爬行运动训练对脑缺血幼鼠心理行为的影响。方法59只7~8日龄新生鼠随机分为对照组20只,仅做颈部皮肤的切开缝合,未结扎双侧颈总动脉;脑缺血组20只,结扎双侧颈总动脉;脑缺血运动组19只,结扎双侧颈总动脉后4 d,给本组幼鼠在自制的空间运动架上进行早期空间运动训练4周。对照组和脑缺血组不给与空间爬行训练。应用动物行为学平台(转棒仪和旷场试验)对38~40日龄幼鼠进行运动和行为功能测定。结果(1)脑缺血运动组和对照组幼鼠降落的潜伏期明显长于脑缺血组(t=4.159,P<0.01;t=4.696,P<0.01),而对照组和脑缺血运动组的幼鼠运动降落的潜伏期长短差异无统计学意义(t=1.418);(2)在旷场实验中3组幼鼠运动的总路程,以及平均速度比较差异均无统计学意义;(3)脑缺血运动组和对照组幼鼠的跨格次数、周边活动时间和距离明显长于脑缺血组( t=4.848,P<0.001,t=6.583,P<0.001;t=2.764,P<0.05,t=3.988,P<0.01;t=3.102,P<0.05,t=3.258,P<0.05),而对照组和脑缺血运动组的幼鼠的跨格次数、周边活动时间和距离长短差异无统计学意义;(4)脑缺血运动组和对照组幼鼠中心活动时间及路程明显短于脑缺血组(t=4.881,P<0.01;t=3.533,P<0.01;t=3.783,P<0.01,t=3.142,P<0.05),脑缺血运动组和对照组幼鼠中心活动的时间和距离比较差异无统计学意义。结论脑缺血幼鼠表现情绪异常,运动行为状态明显受损,早期空间爬行运动训练可明显改善脑缺血幼鼠运动和协调能力及认知能力。
目的:觀察空間爬行運動訓練對腦缺血幼鼠心理行為的影響。方法59隻7~8日齡新生鼠隨機分為對照組20隻,僅做頸部皮膚的切開縫閤,未結扎雙側頸總動脈;腦缺血組20隻,結扎雙側頸總動脈;腦缺血運動組19隻,結扎雙側頸總動脈後4 d,給本組幼鼠在自製的空間運動架上進行早期空間運動訓練4週。對照組和腦缺血組不給與空間爬行訓練。應用動物行為學平檯(轉棒儀和曠場試驗)對38~40日齡幼鼠進行運動和行為功能測定。結果(1)腦缺血運動組和對照組幼鼠降落的潛伏期明顯長于腦缺血組(t=4.159,P<0.01;t=4.696,P<0.01),而對照組和腦缺血運動組的幼鼠運動降落的潛伏期長短差異無統計學意義(t=1.418);(2)在曠場實驗中3組幼鼠運動的總路程,以及平均速度比較差異均無統計學意義;(3)腦缺血運動組和對照組幼鼠的跨格次數、週邊活動時間和距離明顯長于腦缺血組( t=4.848,P<0.001,t=6.583,P<0.001;t=2.764,P<0.05,t=3.988,P<0.01;t=3.102,P<0.05,t=3.258,P<0.05),而對照組和腦缺血運動組的幼鼠的跨格次數、週邊活動時間和距離長短差異無統計學意義;(4)腦缺血運動組和對照組幼鼠中心活動時間及路程明顯短于腦缺血組(t=4.881,P<0.01;t=3.533,P<0.01;t=3.783,P<0.01,t=3.142,P<0.05),腦缺血運動組和對照組幼鼠中心活動的時間和距離比較差異無統計學意義。結論腦缺血幼鼠錶現情緒異常,運動行為狀態明顯受損,早期空間爬行運動訓練可明顯改善腦缺血幼鼠運動和協調能力及認知能力。

Objective To investigate the psychological behavior effects of space creep exercise training for early age cerebral ischemia rats.Methods 59 neonatal rats were randomly divided into 3 groups, 20 in control group with only the neck skin incision and suture, without bilateral common carotid artery ligation;20 in cerebral ischemia group with bilateral common carotid artery ligation;19 in cerebral ischemic exercise group , 4 days after bilateral common carotid artery ligation, given a 4 weeks creep space exercise training with homemade exercise rack.Control group and cerebral ischemia group did not receive exercise training.The Animal Behav-iour Science Platform ( Scotch instrument and open-field test) was used to measure the movement and behavior of these 38-40 days old rats.Results (1) The landing incubation period in cerebral ischemic exercise group and the control group was much longer than in cerebral ischemia group (t=4.159, P<0.01;t=4.696, P<0.01), while the control group and cerebral ischemia exercise group had no significant difference (t=1.418).(2) In the open field test, 3 groups had no significant difference in the total distance and average speed (all P>0.05).(3) Peripheral activity time and distance in cerebral ischemic exercise group and the control group were much lon-ger than in cerebral ischemia group (t=4.848, P<0.001, t=6.583, P<0.001;t=2.764, P<0.05, t=3.988, P<0.01;t=3. 102, P<0.05, t=3.258,P<0.05) , while the number of cross-grid times, peripheral activity time and distance between the control group and cerebral ischemic exercise group had no significant difference.(4) Center activity time and distance in cerebral ischemic exer-cise group and the control were was much shorter than in cerebral ischemia group (t=4.881, P<0.01;t=3.533, P<0.01;t=3.783, P<0.01, t =3.142, P <0.05), while the cerebral ischemic exercise group and the control group had no dignificent difference. Conclusion For the cerebral ischemia rats, movement and behavior state are impaired, early space creeping exercise training can significantly improve the movement, coordination and cognitive abili-ties.
