Abstract
The purpose of this paper was to determine whether there is a diurnal plasma arginine vasopressin (AVP) rhythm in rats. Using an AVP radioimmunoassay, plasma AVP levels were determined at frequent intervals throughout a 24-hour period in adult male rats. Our data revealed a diurnal rhythm in plasma AVP levels, with mid-afternoon and early evening levels significantly greater than those in the morning and late evening.
