[Histotopics of glycosidases in the accessory sex glands of bull (author's transl)].

The histochemical distribution of 4 glycosidases (alpha-Mannosidase, beta-Glucuronidase, N-Acetyl-beta-glucosaminidase and beta-Galactosidase) has been studied in the accessory sex glands of bulls. All glcosidases displayed the highest activity in the distal part of the caput epididymidis and in the cauda epididymidis. A distinct activity of N-Acetyl-beta-glucosaminidase and beta-galactosidase was observed in the seminal vesicle, the ampulla ductus deferentis and in the prostatic gland. In the epithelium of the bulbourethral gland only a weak content of beta-Galactosidase could be demonstrated histochemically. The functional role of the glycosidases in the accessory sex organs is discussed briefly.
