description | The distribution and selectivity of complex carbohydrates in the eccrine glands of the digital pads in the North American raccoon (Procyon lotor) were studied using light and electron microscopic histochemical methods, particularly lectin histochemistry. In the eccrine glands, the dark cells exhibited neutral and acidic glycoconjugates with different saccharide residues (a-L-fucose, b-D-galactose, b-N-acetyl-D-glucosamine and N-acetyl-neuraminic acid); the clear cells contained numerous glycogen particles and showed a distinct reaction of a-L-fucose. The presence of complex carbohydrates with various terminal sugars was evident in the excretory duct cells. In addition, b-D-galactose and N-acetylneuraminic acid residues were mainly observed in the luminal secretion. The glycoconjugates produced by the eccrine glands of the raccoon digital pads may protect the epidermis against physical damage or microbial contamination. In this way, the normal functioning of the sensory apparatus of the foot pads is ensured. |
