title: [The ability of cestodes to synthesize serotonin].
abstract: The ability of the parasitic flat worms Hymenolepis diminuta and Mesocestoides corti to synthetize serotonin (5-HT) has been investigated by means of incubation the worms in metabolic precursor of 5-HT, L-tryptophan, and monoamineoxidase inhibitor, indopan, followed by spectrofluorimetric determination of the tissue level of 5-HT. To avoid possible inhibition of 5-HT synthesis by exogenous 5-HT of the host, experiments were carried out on worms in which the level of 5-HT was previously decreased by reserpine. The increase in the level of 5-HT in tissues after incubation of the worms in L-tryptophan and indopan was observed, indicating their ability to synthetize serotonin from tryptophan.
