Abstract

The present study was undertaken to know the localization of different enzymes in testicular parenchyma in domestic pig. Neutral mucopolysaccharides and acid mucopolysaccharides were mild in testicular capusule and strong in interstitial tissue of testis. Leydig cells of interstitium showed adundant glycogen. Lipids were localized moderately and strongly in the seminiferous tubules and Leydig cells respectively. Moderate to strong reactions for basic proteins were observed in testicular parenchyma of testis. The activities for acid phosphatases and alkaline phosphatases were localized mainly in the interstitial tissue of testis and very mild in seminiferous tubules. The reductase i.e., succinic dehydrogenase enzyme activity was localized strongly in the interstitial tissue of testis.
