Glutaminase activity in the chick central nervous system during postnatal growth.
1. Glutaminase activity was evaluated in the chick cerebral hemispheres, optic lobes and cerebellum between the 1st and 30th day of postnatal growth. 2. Glutaminase activity is higher in the cerebral hemispheres than in the optic lobes and is lowest in the cerebellum. 3. It seems to be inversely related to the magnitude of the variations of glutamine concentration in the three areas. 4. No direct relation exists between enzyme activity and glutamate concentration in the three tissues.
