title: Effect of amygdaloid kindled seizures during pregnancy on neonatal brain biogenic amines.
abstract: The effects of amygdaloid kindled seizures during pregnancy on the concentrations of noradrenaline (NE), dopamine (DA) and serotonin (5HT) and of their respective metabolites, 3-methoxy-4-hydroxyphenylglycol (MHPG), normetanephrine (NMN), homovanillic acid (HVA) and 5-hydroxy-indoleacetic acid (5HIAA), have been studied in the cerebral cortex, brain stem and cerebellum of rat offspring at birth. The levels of DA and NE were increased and those of HVA and MHPG were not modified in the cortex. The levels of DA, NE, 5HT, MHPG and 5HIAA were increased in the cerebellum. The brain stem presented a decrease in DA and 5HT levels, but increased MHPG and HVA levels. It is suggested that, in order to investigate possible changes in the biogenic amine levels on the postnatal period, carefully planned prospective studies are needed.
