A Cytochemical Investigation on the Sweat Glands of the Monkey

Abstract

The authors examined the s weat glands in the facial region, the upper extremity and the palm from the cytological and cytochemical view-points, and obtained the following conclusions.
1) On the activity of alkaline pho s p hatase: In the apocrine sweat glandular duct the activity is intensive at the portion that faces the cavity of the glandular cells. The activity gets weak in order of the myoepithelial cells, karyoplasm and cytoplasm. In the eccrine sweat glandular ducts, the activity is extremely intensive at the base of the glandular cells, and in order of the portion that faces the cavity of the glandular cells, karyoplasm, cytoplasm of the basal cell and cytoplasm of the superficial cell, the activity is weak. In conclusion, as for noticeable differences in the activity between the apocrine and eccrine sweat glands, the portion that faces the cavity of the glandular cells, the base of the cells and the A Cytochemical Investigation on the Sweat Glands of the Monkey 493myoepithelial cells attract special attention. Moreover, the portion that faces the cavity of the glandular cells in the eccrine sweat glandular ducts in the hairy transitional region of the palm shows a medium activity, on the other hand that portion in the eccrine sweat glandular ducts in the palm shows a weak activity. Not any activity is observed in the excretory ducts of the apocrine and eccrine sweat glands.
