title: Involvement of nitric oxide in 2-deoxy-D-glucose-induced hyperphagia in rats.
abstract: The effects of a nitric oxide (NO) synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME) on 2-deoxy-D-glucose (2-DG)-induced hyperphagia were investigated in rats. L-NAME dose-dependently inhibited 2-DG-induced eating in non-food-deprived rats, although the inactive isomer D-NAME on 2-DG-induced hyperphagia were inhibited by co-administration of L-arginine. The neuronal NO synthase inhibitor 7-nitroindazole also inhibited 2-DG-induced hyperphagia. These results suggest that 2-DG-induced hyperphagia is linked with NO and that brain NO may participate in this hyperphagic model.
