[Enzyme histochemical studies on the epithelium of the epididymis of the tomcat (author's transl)].

The histochemical localization of some oxidoreductases was investigated in the epididymides of adult tomcats. Succinate dehydrogenase, lactate dehydrogenase, beta-hydroxybutyrate-dehydrogenase revealed their highest activity in corpus and cauda epididymidis whereas glucose-6-phosphate-dehydrogenase was strongest in the caput. The activity of the diaphorases and of cytochrome oxidase in the epididymal epithelium increased from caput towards the cauda epididymidis.

[Histotopics of lysosomal enzymes in the epididymis of the tom-cat (author's transl)].

The histochemical localization of 6 lysosomal enzymes was studied in the epididymis of adult tomcats. A weak to distinct reaction for acid phosphatase, leucyl-amino-peptidase and non--specific esterase could be observed in the epithelium of the ductus epididymidis in all three segments. Among the glycosidases, N-acetyl-beta-glucosaminidase displayed the strongest activity.
