| Abstract: | The activity of gamma-glutamyl transferase (GGTF, EC 2.3.2.2) has been investigated in different brain structures (hemispheres, cerebellum, hippocamp, brain stem) of newborn, 3-8-, 15-, 21-30-day and adult rats and piping hare. In both animals, the activity of this enzyme in all the structures investigated increases during ontogenesis. Interspecific differences were found in the increase of the enzymic activity in different brain structures during ontogenesis as well as in the level of the activity in different structures in mature animals. |
