Infraorbital glands of a male Formosan serow (Capricornis crispus swinhoei).
The morphology of the infraorbital glands of a male Formosan serow was examined. The glands consisted of an inner sebaceous portion and an outer apocrine portion. The inner sebaceous portion was much larger than that of the male Japanese serow. The sebaceous portion of the gland consisted of the ordinary and modified types of tissue that are present in the infraorbital gland of the female Japanese serow, and the modified tissue contained some melanin granules and melanocytes. The apocrine portion of the glands was composed of tubules in which the myoepithelial cells stained intensely to very weakly upon immunohistochemical staining with antibody against a smooth muscle actin. Nerve fibers that contained calcitonin gene-related peptide were scattered in the apocrine portion. These findings indicate that the sebaceous gland of the male Formosan serow is different from that of the male Japanese serow but rather similar to that of the female Japanese serow. Moreover, the apocrine gland is innervated by peptide-containing nerve fibers.
