【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。
[Abstract]:The tissue of the hoof wall and hoof was fixed with 4% paraformaldehyde, the softened solution was dehydrated, transparent, soaked in wax and embedded sections, stained by Weigert-VG and Sacpic, observed microscopically and photographed.The results showed that the hoofbox of Huang-Huai Mountain includes the structure of hoof edge, hoof, hoof, hoof, hoof, hoof, hoof, hoof, and hoof, while hoof, hoof wall mainly includes cuticular layer, transparent layer, granular layer, spinous cell layer, papillary layer and reticular layer structure, but there is no transparent layer in hoof bottom.There is abundant arteriovenous anastomosis in the subcutaneous tissue of the sole of the hoof, and the alternative chimeric structure between the horny lobule and the dermis lobule of the hoof wall can make the hoof and the hoof firmly bound together.The hoof is rich in fat tissue and elastic fiber.These results provide morphological data for the further study of the histological structure of the Arthropodes angustifolia in Huang-Huai Mountain.
