Profil enzymatique des sécrétions utérines de la vache au cours du cycle oestral

摘要

The uterine secretions of 20 bovine females have been studied and the activity of the following five enzymes has been evaluated: aldolase, glucose-t-phosphodeshydrogenase (G-6-PDH), sorbitol deshydrogenase, glutamic pyruvic transminase. Significant cyclic variations have been observed for aldolase and G-6-PDH, aldolase activity being maximum during the estrogenic phase of the cycle whereas G-6-PDH activity has been more important during the progesteronic phase. These results indicate a significant uterine metabolic activity during the different phases of the reproduction processes.
