Histology and Cytochemistry of Human Skin
1. In the epidermis non-specific esterase activity outlines a strongly reactive band between the stratum granulosum and the stratum corneum. In the epidermis of the palm, there is no such esterase-rich band. 2. The outer sheath of active hair follicles has strong enzyme activity. The degenerating hair bulb in catagen follicles is very strongly reactive, and clusters of cells around the hair clu...
متن کاملHistology and cytochemistry of human skin. XIX. The development and fate of the axillary organ.
The development and fate of the apocrine sweat glands in the axilla are not yet well elucidated. The development (Borsetto, 1951 (1)), the structure and function (Shelley and Hurley, 1953 (2); Rothman, 1954 (3); Montagna, 1956 (4)), and the ageing changes (Montagna, 1956a (5); Winkelmann and Hultin, 1958 (6)) of these glands are relatively well understood, but very little is known about their d...
متن کاملHistology and cytochemistry of human skin. VIII. Mitochondria in the sebaceous glands.
Mitochondria are not difficult to demonstrate in sebaceous cells. Yet, they are only briefly described in the literature. Nicholas et al (4) believed that mitochondria in sebaceous cells undergo a direct transformation into lipid droplets. In the sebaceous glands of the mouse the mitochondria are said to increase in number at the beginning of lipid storage, to decrease during sebaceous transfor...
متن کاملComparative histology and immunohistochemistry of porcine versus human skin.
BACKGROUND Porcine skin is increasingly being employed as a model of human skin in various research fields, including pharmacology, toxicology and immunology, with particular interest in percutaneous permeation and organ transplantation. Porcine skin shows several anatomical and physiological similarities, but also some differences, with human skin, but few in depth comparative studies are so f...
متن کاملAging skin: histology, physiology, and pathology.
Skin is a complex organ covering the entire surface of the body. Aged skin is characterized by appearance of wrinkles, laxity, and pigmentary irregularities. These changes occur under the influence of intrinsic and extrinsic factors, with sun exposure being the most deleterious to the skin. Skin changes associated with aging are the focus of many surgical and nonsurgical procedures aimed to imp...
