| 摘 要： | 目的:探讨并、缺指畸形胎儿指皮组织学结构与正常胎儿结构的差异.方法:观察并、缺指畸形胎儿大体形态,常规取材,HE染色,通过光学显微镜观察指皮组织学结构.结果:并、缺指畸形胎儿镜下观察指皮分层及附属结构与正常胎儿相似,但表皮颗粒层和棘层内朗格汉斯细胞比正常胎儿明显增多,未见触觉小体和环层小体.结论:并、缺指畸形胎儿的致畸因子可能影响其感觉神经末梢的发育和成熟,朗格汉斯细胞增多可能是遗传因素的作用或环境影响所致.

| Abstract: | Purpose: To discuss the differences of the histological structure of finger skin between syndactly and extrodactyly foetus and normal foetus.Method: To observe the configuration of syndactly and extrodactyly foetus,draw materials generally,then dye with the methods of H.E,finally observe the finger skin histological structure under the light microscope.Result: The study shows that the finger epidermis delamination and accessorial structure of syndactly and extrodactyly foetus resembles normal foetus,but the quantities of Langerhans cell in the stratum granulosum and stratum spinosum of epidermis are obviously more than those in normal foetus,and can't find tactile corpuscle and lamellar corpuscle.Conclusion: The teratogen of syndactly and extrodactyly foetus possibly influences the development and maturation of sensory nerve ending.Genetic factor or environmental influence possibly conduces to the increase of Langerhans cell. |
