The monoamine oxidase activity in the cerebral hemispheres decreased significantly after 2, 4, 8 and 16 hr of 6-amino-nicotinamide (35 mg/kg body weight, i.p.) administration. In the cerebellum, the MAO activity was not affected significantly. In the brain stem, however, a significant increase was observed after 2 hr of drug administration followed by a gradual decrease at later time intervals. The Na+K+ATPase activity in the cerebral hemispheres was increased significantly at 2 and 4 hr of 6-aminonicotinamide administration. This was followed by a gradual decrease at later time intervals. In the cerebellum, like monoamine oxidase, the Na+K+ATPase did not change significantly. The brain stem showed a decrease at 2 hr of drug administration, followed by a significant increase at 4 hr and then a gradual decrease to near control values.
