【摘要】 目的　探讨空瓶刺激诱发的慢性情绪应激对大鼠行为的影响及行为变化的趋势。方法　利用空瓶刺激诱发的情绪应激模型 ,观察记录连续 1 4次 ,每次 1 0分钟的情绪应激期间 ,情绪应激组、对照组和生理应激组大鼠的攻击性行为、探究行为和修饰行为的表现。结果　连续 1 4次的情绪应激期间 ,与对照组和生理应激组相比 ,情绪应激组大鼠均表现出明显的攻击性行为 ,而对照组和生理应激组大鼠仅表现为探究和修饰行为。结论　慢性情绪应激能诱发大鼠行为的明显改变 ,且这种行为的改变与应激频率无关。更多还原

【Abstract】 Objective To explore the effect of chronic emotional stress on the behaviors of rats and its changing trend. Method Utilizing the animal model of emotional stress induced by empty water bottles, rats were divided into three groups:emotional stress group, control group and physiological stress group. During 14 times emotional stress procedure, 10 minutes per time, attacking, exploring and grooming behaviors of rats in three groups were investigated and recorded. Results During 14 times emotional stress procedure, compared to rats in control and physiological stress groups, rats in emotional stress group always expressed significant attacking behavior, and rats in control and physiological stress groups expressed exploring and grooming behaviors. Conclusion During chronic emotional stress procedure, behaviors of rats in emotional stress group changed significantly, which was independent of stress frequency.更多还原
