Abstract
p-Chlorophenylalanine (PCPA) treatment reduced pineal 5-hydroxytryptamine (5-HT) levels by 68.9% of non-PCPA treated levels in intact rat pineal glands and by 95.9% of non-PCPA treated levels in adrenergically denervated rat pineal glands. Although isoproterenol stimulation resulted in increased activity of serotonin N-acetyltransferase (NAT) activity in all experimental groups, pineal melatonin production was maximal only in non-PCPA treated rats, suggesting that 5-HT concentrations may exert considerable influence on the level of melatonin production in the rat pineal gland, independent of the level of NAT activity.
