Plasma vasopressin concentration in the anaesthetized dog before, during and after atrial distension

J R Ledsome et al. J Physiol. 1983 May.

Abstract

Plasma vasopressin (AVP) concentration in dogs anaesthetized with chloralose was measured by radioimmunoassay and was within the range of 2-5 pg/ml. during control periods. Distension of the left atrium led within 2 min to a fall in plasma AVP concentration which reached a steady lower value within 4 min. After cessation of atrial distension the AVP concentration returned to pre-distention values within 4 min. Cooling the cervical vagosympathetic nerves to 8-10 degrees C led to a rise in plasma AVP concentration. Atrial distension during cooling of the vagi resulted in a further increase of plasma AVP concentration.
