title: [Effect of vasopressin and oxytocin on the spontaneous activity of dorsal horn cells of the isolated spinal cord of the rat pup].
abstract: The effect of vasopressin and oxytocin on background frequency of single cells from the dorsal horn was studied in the isolated spinal cord of 2-3 weeks old rats. It was shown that neurons were predominantly depressed following application both of vasopressin or oxytocin. Vasopressin evoked depression of background activity in 74% cells (29 of 39 responding to vasopressin) and activation in 26% cells (10 from 39). Oxytocin evoked depression in 67% (14 from 21 responding to oxytocin) and activation in 33% cells (7 from 21). All effects were reversible and dose-dependent. Neurons studied either gave the same response both to vasopressin and to oxytoxin or responded only to one of the two peptides.
