通过组化定量分析的方法，观察不同月龄胎儿表皮中多糖及核酸的动态变化。探讨胎儿皮肤之表皮发育过程的一般规律。结果表明，表皮中核酸之平均光密度值随月龄的增加而增高，考虑与胎儿器官组织的生长分化日趋旺盛有关。多糖的平均光密度值在表皮之表层及中间层均随月龄的增高而减小，考虑与胚胎早期心血管功能尚不完善有关。而基底层平均光密度值在各月龄均较低，与基底层细胞邻近真皮结缔组织血管，营养容易获取有关
Through the method of group quantitative analysis, observe the dynamic changes of polysaccharides and nucleic acids in fetal epidermis at different months of age. Explore the general rules of fetal skin epidermal development. The results showed that the average optical density of the epidermis increased with the increase of age, consider the growth and differentiation of fetal organ tissue is increasingly exuberant. The average optical density of polysaccharides in the epidermis of the surface layer and the middle layer with the increase of age decreases, consider the early embryonic cardiovascular function is not perfect. While the basal layer average optical density value at each age were lower, and basal cells adjacent dermal connective tissue vessels, nutrition is easy to get
