用组织学方法研究家犬嗅球的结构,观察家犬嗅球内结构的性别和年龄差异,依据常规HE染色法及数理统计学原理对家犬嗅球各层宽度,丰要细胞的数量进行比较统计学分析,探讨嗅球内部结构的发育过程以及性别差异对雌雄动物嗅觉差异的影响.结果表明:雌雄幼年家犬嗅球内各层结构差异不显著;成年家犬也表现出同样的结果,但足成年动物的僧帽细胞彤态、数量差异极显著.分析发现,幼年家犬嗅球各层结构都已比较明显,成年家犬嗅球体积和重量明显增加,各层宽度明显变宽,各层细胞密度显著降低,说明嗅球也处在不断的发育完善过程之中.同时僧帽细胞的差异可能是造成雌雄动物嗅觉差别的原因之一.

The purpose of this article is to detect sex and age difference in the structure of the olfactory bulb in dogs by histological methods. The thickness of the olfactory bulbs layers and its main cells were analyzed comparatively with the methods of HE-staining and statistics, through which we studied the development course of dogs' olfactory bulb and the structural differences which affect the olfaction in both males and females. The results showed that between both male and female juveniles and adult males and females, the difference in thickness of each layer is not significant. But the difference in quantity of mitral cells between adult males and females was significant. Meanwhile, the structure of every layer in juvenile dogs was apparent while the volume and the weight of adult dogs' olfactory bulb and each layer's width increased significantly. On the other hand, the density of each layer's cells decreased apparently. Our results demonstrated that the olfactory bulb developed with age, and the apparent differences in morphology and quantity of mitral cells between males and females may be one of the reasons leading to the sexual variations of olfactory sensitivity.
