Poll glands of the one-humped camel were obtained to examine their secretory mechanism by lectin histochemistry, immunohistochemistry and scanning electron microscopy. The glands were composed of numerous conical lobules which consisted of apocrine tubules. Lectins of peanut agglutinin (PNA), Dolicos biflorus agglutinin (DBA) and wheat germ agglutinin (WGA) showed a variety of staining in the Golgi areas and secretory granules in secretory cells of the apocrine tubules. Most myoepithelial cells stained intensely with a-smooth muscle actin. Varicose nerve fibers immunostained with protein gene product 9.5 were scattered among apocrine tubules. Scanning electron microscopy revealed that the luminal surface of secretory cells was covered with microvilli and that secretory cells pinched off smooth-surfaced apocrine blebs. After pinching off, crater-like pits remained on the luminal surface of secretory cells. These findings are similar to those obtained from the infraorbital glands of the serows.

D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D009130 Muscle, Smooth Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant.

D000199 Actins Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.
