Experiments on rats were carried out to study the effects of administration of delta-sleep-inducing peptide (DSIP) and its analogs (9-14) into the reticular part of the substantia nigra and ventral hippocampus on picrotoxin- and kainate-induced epileptic activity. Additionally, the uptake of [3H]tryptophan by brain structures was studied. Intranigral and… (More)
A seizure-protecting effect of the delta-sleep-inducing peptide (DSIP) and its analogues was revealed. An intensive sorption of H3 tryptophan occurred under the effect of the DSIP and its analogues. The data obtained suggests that the serotoninergic system plays no important part in the seizure-protecting effect.
