In rat lung membranes, oxytocin displaced [3H]AVP binding, with the lowest potency among the native neurohypophysial peptides tested.
In plain wordsIn lab tests on rat lung membranes, oxytocin competed with vasopressin for binding, but less strongly than the other natural peptides tested.

Source sentences
Competitive inhibition of [3H]AVP binding showed that neurohypophysial hormones as well as their synthetic analogues displaced [3H]AVP in a concentration-dependent manner. The order of potencies for the native peptides was: AVP > lysine vasopressin = arginine vasotocin > oxytocin.
