摘　　要：目的探讨兔耳血管系统的形态学特点,为动物模型的建立提供参考。方法 50只日本大耳白兔耳,采用活体观察、巨微解剖和铸型佐证方法,观测耳廓前后动脉的起源、走行、分支及分布;耳廓前后静脉的属支、汇入及分布;耳廓血管间的吻合关系。结果兔耳皮肤白皙菲薄、血管分布表浅,血管间的联系清晰可见;动脉分为耳廓前动脉和后动脉,耳廓前后动脉均分为前支、后支;静脉分为耳廓前静脉和耳廓后静脉,相互吻合形成耳缘静脉;耳廓动脉、静脉间存在动静脉吻合,数量由中央区到外周区渐次增多。结论日本大耳白兔的兔耳血管恒定、分布表浅、容易观察,可用于建立系列兔耳模型。Objective To explore the morphological features of the blood vessel of rabbit＇s ear for reference of build- ing animal model. Methods Totally the 50 ears were investigated by in-vivo observation,macro- microscopic dissec- tion and corrosive vascular cast.The features were observed under surgical magnifier： The origin, courses and distribu- tion, the tributaries,distribution of anterior and posterior auricular vein, the anastomoses between the artery and vein. Results The skin of the ear was white and tender,the vascular clearly visible. The artery divided into anterior and posterior one. And the anterior auricular artery further divided into anterior and posterior branch. The vein divided in- to anterior and posterior one, forming marginal vein. The vessels of the ear have a lot of arteriovenous shunt, particu- larly at the margin of the ear. Conclusion The ear of Japanese white rabbit exist the characteristics, such as vascular constant, distribution superficial and observation easily. This research can provide theoretical reference for building rabbit＇s ear model.
