説明

The axillary sweat glands (eccrine and apocrine glands) in ten Japanese children of ages varying from immediately after birth to 15 years, one embryo of 8 fetal months and one adult of 25 years were histochemically investigated by means of PAS technique and Perls Stied a's Berline-blue reactive method and the following results were obtained. 1. In the eccrine sweat glandular duct, the PAS positive substances with an extreme intensity were recognized in the glandular cells of the basement in only two cases during the infant period but PAS positive substances in the other portions were gradually and slightly increased in their qnantity with the advance of age. On the other hand, in the glandular duct of the apocrine sweat gland, PAS positive substances exsisted of but a trifle in the children before the first half of the school period. 2. The PAS positive substance s in the glandular cells of the eccrine sweat gland were numerous in the cytoplasm near the lumen during the new born period. After and at the infant period, the PAS positive substances were similarly abundant in the basal and surface cells or somewhat more numerously in the basal cells. In the children of school age, small granular PAS positive substances were recognizable in the surface cells. 3. The PAS positive substances in the intercellular canaliculi were recognized in children after the infant period and they were slightly increased with the advance of age. 4. The PAS positive substances that are intensively reactive in the brush border and cytoplasm of the glandular cells of the apocrine sweat gland, were recognizable during the later period of infant time, and they were various and numerous after the middle period of school age. Moreover, the contents of the glandular lumen were various and numerous after the middle period of school age. 5. In the myoepithelial cells, the PAS positive substances were recognized in the eccrine sweat gland of the whole cases examined and in the apocrine sweat gland of the children after the later period of school age. That is, the PAS positive substances in the children at the first half period of school age are observable in only one case in the apocrine sweat gland. 6. In the proper layer of the m ucosa the PAS positive substances were recognizable in the inner layer of the whole examined cases in both kinds of the sweat gland, and they were also observable in the outer layer of the cases after the infant period. 7. The iron positive substances were found in the cytoplasm just below the hyaline cuticular layer of the glandular cells of theapocrine sweat gland and in the contents of the glandular lumen in the persons after puberty.
