Comparative estimation of octopamine in the aortic smooth muscle, plasma and red blood cells of spontaneously hypertensive and Wistar Koyoto control rats.
Octopamine is an alpha agonist, the levels of which vary with age and in pathophysiological conditions. The levels of octopamine were found to be higher in the aortic smooth muscle and red blood corpuscles, but lower in the plasma of spontaneously hypertensive rats (SHR) than in the Wistar Koyoto rats. The importance of these variations are discussed.
