| Abstract: | Consumption of diphosphate nucleosides is investigated by histochemical methods in rat and cat nervous system. Results show NDP-ase is effectively in histological sections from animals previously perfused with glutaraldehyde or formaldehyde. Histochemical reaction is increased in presence of Ca++, Mg++, Mn++ or imidazole and inhibited by L-DOPA and Noradrenaline in incubation medium. A comparative study of TPP-ase and NDP-ase activities to dilucidate the identity of both enzymes is described. |
