The skin of Xenopus laevis contains a soluble beta-galactoside-binding lectin with a approximately 16,000-mol-wt subunit. It resembles similar lectins purified from a variety of tissues from other vertebrates, and differs from two other soluble X. laevis lectins from oocytes and serum that bind alpha-galactosides. The skin lectin is concentrated in the cytoplasm of granular gland and mucous gland cells, as demonstrated by immunohistochemistry with the electron microscope. Upon injection with epinephrine, there is massive secretion of the cytoplasmic lectin from the granular gland cells.

The histological and histochemical structure of lingual salivary glands in mole rat (Spalax leucodon) were studied using histochemical staining techniques to provide information of its salivary glands. A total of five adult mole rat (Spalax leucodon) were used as the material. It was observed that serous and mucous glands are placed in the root of the tongue. It was detected that although the mucous gland cells were rich in terms of AB pH 0.5, 1.0, 2.5 and AF (+) mucosubstance, the PAS and KOH/PAS mucosubstances showed very weak reaction, and this mucosubstances were present at a very less amount in serous gland cells. In the PAS/AB staining, it was found that the serous and mucous gland cells showing only AB or only PAS reaction and also AB AB pH 2.5 (+) cells were found. The same findings were observed in serous glands by AF/AB staining. Consequently, the present study demonstrated characteristic features of the lingual salivary glands of the mole rat, and it revealed histological and histochemical data both in accordance with and different from that for the lingual salivary glands of mammals and other species.

A histochemical study of the epidermal gland secretions in earth worm Megascolex mauritii has been made. The secretions of the aluminous gland is a glyco or mucoprotein and that of the mucous gland cells is an acid mucopolysaccharide. Two types of mucous glands are present in the epidermis, the small and large mucous glands, secreting hyaluronic acid and highly acidic sulphated mucopolysaccharide, respectively.The functions of the secretions from these glands are investigated. The albuminous and small gland cells secrete mucin under normal conditions and this mucin keeps the body surface moist and serves as lubricant during locomotion. The large mucous gland secretes only after irritation and its secretion may be an alarm pheromone.
