Comparative Study[The dependence of shifts in arterial pressure and cardiac output during alpha-adrenoreceptor stimulation on the initial (controlled) tonus of arterial vessels in rats].
A significant decrease in arterial pressure and total peripheral resistance occurred following elevation of the initial blood pressure to 160 mm Hg with mesathone in anesthetised rats. The increase in the cardiac output remaining unchanged. Vascular and cardiac mechanisms of the revealed relationships are discussed.

Comparative Study[The effect of the initial (controlled) tonus of the arterial vessels on the correlation of arterial pressure and cardiac output during a pressor reaction to a rapid blood volume increase in rats].
A considerable decrease in pressor responses to polyglykine at an elevated arterial tone and constant increase of cardiac output occurred in anesthetised rats. Vascular and cardiac mechanisms of the interrelationship are discussed.
