Inhibitory effect of atropine on the isoprenaline-induced increase in vasopressin plasma concentration in rats.
The isoprenaline-induced increase in plasma levels of vasopressin in conscious rats was reduced by intravenous and intracerebroventricular applications of atropine. It is concluded that central neurons with muscarinic receptors contribute to the isoprenaline-induced vasopressin release.
