  • Title: Plasma vasopressin response to haemorrhage in the anaesthetized rabbit.
    Author: Rankin AJ, Kelpin BG, Courneya CA, Wilson N, Ledsome JR.
    Journal: Can J Physiol Pharmacol; 1986 Jul; 64(7):904-8. PubMed ID: 3768798.
    Abstract:
    In chloralose-urethane anaesthetized rabbits the acute circulatory and plasma vasopressin (pAVP) responses to moderate haemorrhage of 6 mL/kg body weight (10% blood volume) were followed after serial section of the aortic, vagus, and carotid sinus nerves. With all nerves intact, haemorrhage resulted in significant increases in pAVP, accompanied by decreases in systemic arterial pressure and right atrial pressure. With subsequent section of each afferent nerve, pAVP still increased in response to haemorrhage regardless of the order of nerve section. These results suggest that, in the anaesthetized rabbit, there is a further component of the pAVP response to haemorrhage, in addition to those carried in the aortic, vagus, and carotid sinus nerves.
