摘　　要：为观察黄淮白山羊蹄部的解剖及组织结构特征,应用大体解剖学及组织学研究方法,将10只成年黄淮白山羊麻醉后处死,取其中2只的蹄供解剖学观察,另外8只分别取蹄底、蹄壁和蹄球部组织,经4%多聚甲醛固定,软化液软化后脱水、透明、浸蜡及包埋后切片,通过HE、Weigert-VG和Sacpic染色,显微观察并摄影。结果,黄淮白山羊蹄匣包括蹄缘、蹄冠、蹄壁、蹄底和蹄球等结构;蹄底、蹄壁主要包括角质层、透明层、颗粒层、棘细胞层、乳头层和网状层结构,但蹄底无透明层,蹄底皮下组织中含丰富的动静脉吻合,蹄壁角质小叶和真皮小叶交替嵌合结构明显,可使蹄匣与肉蹄牢固的结合在一起。蹄球中含丰富的脂肪组织和弹性纤维,此结构特征是分散蹄部承受外力的结构基础。上述研究结果为进一步研究黄淮白山羊蹄部的组织学结构提供了形态学资料。To observe hoof anatomical characteristic and organization structures of Huanghuai goat,using gross anatomy and histological method,ten adult huanghuai goats were executed after anesthesia. Two goats were observed through anatomy, and the hoof bottom, wall and hoof sphere of the other eight goats were obtained,using 4%paraformaldehyde fixation, dehydration after softening, transparent, soaking,paraffin embedding and making tissue slices,using HE, Weigert-VG and Sacpic methods dyeing, microscopic observation and photography, ln result,capsula ungulae of Huanghuai white goat included hoof edge,hoof crown,hoof wall,hoof sole and hoof sphere;the hoof sole and wall consisted of stratum corneum,stratum granulosum,stratum spinosum,stratum papillare and lamina reticularis,but no stratum lucidum in hoof sole. There were rich arteriovenous anastomosis in subcutaneous tissue of hoof sole,and the structure of alternant gomphosis was obvious between the corneum lobular and eorium lobular. The capsula ungulae combined firmly with corium ungulae because of alternant gomphosis structure. There were rich fat tissues and elastic fibers in the hoof sphere,and this characteristic was the structure foundation of dispersing hoof external force. The above-mentioned results laid the morphological informations for further studies on tissue structres of hoof of Huanghuai white goat.
