Abstract The cutaneous glands of the forehead and the metatarsus were studied by histological and histochemical methods and electron microscopy in adult male and female impalas in various seasons of the year. All glandular areas consist of apocrine and holocrine glands, which, however, occur in different proportions. Our findings in the apocrine gland cells suggest (1) the synthesis and exocytosis of a glycoproteinaceous secretory product stored in secretory granules, (2) typical apocrine… 
Cutaneous Eccrine Glands of the Foot Pads of the Rock Hyrax (Procavia capensis, Hyracoidea, Mammalia)
The secretory product of the eccrine cutaneous glands seems to improve the traction between the foot pads of these animals and the steep and smooth rock formations among which they live.
Cutaneous eccrine glands of the foot pads of the small Madagascan tenrec (Echinops telfairi, Insectivora, Tenrecidae): skin glands in a primitive mammal
The cutaneous glands of the foot pads of the primitive mammal the Madagascan tenrec, Echinops telfairi, are studied to find correlations between skin gland morphology and specific ethological features and conclude that the glands fulfill several functions: production of a fluid-rich secretory product, secretion of antimicrobial peptides and proteins, and playing a role in thermoregulation.
Testicular regulation of seasonal change in apocrine glands in the back skin of the brown bear (Ursus arctos)
The present histological and histochemical findings of changes in the secretory status and glycocomposition of the apocrine glands according to the season and reproductive status suggest that these glands are important for chemical communication.
Human glands of Moll: histochemical and ultrastructural characterization of the glands of Moll in the human eyelid.
The secretory and cytoskeletal components of these apocrine glands in males and females are studied by immunohistochemical methods, and the ultrastructural organization of the glandular cells with an electron microscope suggests a function in local immune defense.
Glycocomposition of the apocrine interdigital gland secretions in the fallow deer (Dama dama).
The lack of sexual and age-related differences in the glucidic content of the glandular secretions seems to indicate that the glycoderivatives may play only an accessory role in the production of odoriferous signals in fallow deer.
Histo‐physiology of the scent‐marking glands of the penile pad, anal pouch, and the forefoot in the aardwolf (Proteles cristatus)
Variable heights of the glandular cells, frequent apical tall protrusions as well as pinched‐off pieces of cytoplasm in the glandsular tubules support the concept of an apocrine secretion in the scent glands, and variable actin staining patterns suggest a dynamic process during which actin filaments form a ring or sheet at the basis of the pinching‐off bleb.
Secretory phenomena in the non-lactating human mammary gland.
The normal non-lactating premenopausal human mammary gland has been shown by immunohistochemistry and transmission electron microscopy to secrete a number of antimicrobial peptides such as

On the basis of histological and ultrastructural findings, this tumor was diagnosed as a tubulopapillary adenocarcinoma, arising from apocrine sweat glands of the skin.
Adaptive evolution of secretory cell lines in vertebrate skin
It is attempted to phylogenetically narrow the large variety of secretory structures in vertebrate skin into a few basic schemes, in the light of the close relationships between environmental challenges and ecological, ethological as well as physiological roles of the cutaneous apparatus.
Histology of the Suprapubic and Anogenital Cutaneous Glands in Male Cotton Top Tamarins (Saguinus oedipus)
It appears, therefore, that light microscopy samples from frozen tissues provide detailed features that can disclose distinctive traits in specimens characterized by different hormonal balances.
