摘要
以中国树鼩为实验对象,采用缩小生活空间和增加同种动物个体数目或给干预的方法,观察慢性环境刺激对中国树鼩生活行为、生理生化的影响。结果发现:与对照组(大饲养笼饲养)比,生活在小饲养笼的中国树鼩的体重明显减轻,血象和胸骨骨髓象各类细胞数均显著增加,雄性树鼩出现睾丸萎缩、阴茎外露下垂、性行为减退。干预组(给利血平)的中国树鼩应激性显著降低,外界环境刺激对生活行为、角斗、体重、血象和胸骨骨髓象各类细胞数、性器官及性行为影响较小。
We investigated the effects of chronic environmental stresses,including living space,group size,and external interference,on the physiological and biochemical behaviors of Chinese tree shrews.Our results revealed that when tree shrews were housed in smaller cages,the average body weights were decreased significantly,while the cell numbers of the blood and sternal bone marrow were increased significantly,as compared to those housed in larger cages.Also,testicular shrinkage and atrophy,penis droopy,and decreased sexual activity were observed in the male tree shrews in smaller cages.Tree shrews treated with reserpine in the intervention group had reduced irritability,and the external environmental stimuli only affected slightly the living behaviors,wrestling,body weight,blood and sternal bone marrow cells,sexual organs,and sexual behaviors.
