[Histochemical study of human nasal mucosa].
The histochemical study of the fetal nasal mucosa collected from fetus of different months is reported. The concentration of succinic dehydrogenase and acid phosphatase in nasal epithelium kept pace with the fetal growth which explained a steady improving metabolism and secretory activity of the fetal nasal mucosa. On the other hand, activities of alkaline phosphatase in the mesenchymal cells, the fibroblasts and the glandular cells were getting weaker and weaker indicating the functional maturation of the fetal nasal mucosa. During the sixth month, mucins occur red in the glands, which showed the establishment of the secretory function in the nasal mucous glands.
