A decrease of the NAD and serotonin level in the brain of rats with PP hypovitaminosis is shown. NAD in concentration of 10(-6) M in vitro exerts a less pronounced inhibiting influence on the neuronal uptake of [14C]serotonin and [14C]GABA by brain synaptosomes of rats with PP hypovitaminosis. GABA content under such conditions increases as compared with the control and correlates with changes in the [14C]GABA uptake system.
