The musk gland of the adult house musk shrews (Suncus murinus) of both sexes was studied lectin histochemically. The musk gland was a kind of scent gland, consisted of congregation of branched or unbranched simple tubuloalveolar gland holocrine in nature and was attached by an apocrine gland-like structure (sweat gland) in the deeper layer of its periphery. Acinar cells of the musk gland were distinguishable into three type from basal to luminal parts of the acinus; immature cells, mature cells and degenerating cells. There was no histological difference between both sexes. Lectin-binding pattern of the musk gland was examined in comparison with that of the sweat gland and ordinary sebaceous gland by histochemical staining techniques using seven lectins: ConA, RCA I, PNA, SBA, UEA-I, DBA, WGA, WGA and PNA labelled the duct of the musk gland more intense than the acinus. Several lectins showed a tendency to label the cells situated near the luminal surface more intense than those near the basement membrane in both the acinus and duct of the musk gland. In the sweat gland and ordinary sebaceous gland, the lectin-binding pattern was different with each other and from that in the musk gland. These findings suggest that the musk gland, sweat gland, and ordinary sebaceous gland are different to each other in nature of cells and the secretion.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012543 Scent Glands Exocrine glands in animals which secrete scents which either repel or attract other animals, e.g. perianal glands of skunks, anal glands of weasels, musk glands of foxes, ventral glands of wood rats, and dorsal glands of peccaries. Gland, Scent,Glands, Scent,Scent Gland
D012627 Sebaceous Glands Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM. Gland, Sebaceous,Glands, Sebaceous,Sebaceous Gland

D013545 Sweat Glands Sweat-producing structures that are embedded in the DERMIS. Each gland consists of a single tube, a coiled body, and a superficial duct. Gland, Sweat,Glands, Sweat,Sweat Gland
D037102 Lectins Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.
