High concentrations of oxytocin in hypophysial portal plasma.

D M Gibbs.   

Abstract

Hypophysial portal blood was collected from pentobarbital-anesthetized male rats, and the content of oxytocin (OT) was measured by RIA. The concentration of OT in portal plasma was 1.88 +/- 0.48 ng/ml (SEM) and was at least 15 times higher than the concentration of OT in peripheral plasma samples from the same rats. Dilutions of portal plasma produced a displacement curve parallel to those of synthetic OT and posterior lobe extract. The data support a possible role for OT as a hypothalamic-releasing hormone.
