Abstract

Histochemical investigation was carried out for the preputial gland of the adult weasels (Mus-tela sibirica coreana). The preputial gland may be classified as a compound alveolar gland (sebaceous gland). The gland was moderately stained with oil red 0 and sudan black B, and strongly with nile blue and victoria blue 4R. The gland showed very strong activities of reduced nicotinamide adenine dinucleotide tetrazolium reductase, lactate dehydrogenase and aldolase, slight or moderate activities of 17β-hydroxysteroid dehydrogenase, 20α-hydroxysteroid dehydrogenase and alkaline phosphatase, slight activities of a-glycerophosphate dehydrogenase, acid phosphatase, 11β-hydroxysteroid dehydro-genase and 20β-hydroxysteroid dehydrogenase, slight or negative activities of malate dehydrogenase and steroid 3β-ol-dehydrogenase, and negative activities of succinate dehydrogenase, β-hydroxybutyrate dehydrogenase and acetylcholine esterase.<BR>Histochemical characteristics of the preputial gland was similar to the alveolar gland (sebaceous gland) found in the anal gland and the sebaceous gland of the skin.
