[Effect of reserpine, isobarin and dopegit on the resistance of cerebral vessels].
In tests staged on anesthetized cats the effects of reserpine, isobarine and dopegit upon the resistance of cerebral vessels were studied resistographically. In 60--120 minutes after their introduction these drugs raise the resistance of intracranial vessels, inhibiting their reaction to electric stimulation of sympathic nerves and bringing down at the same time the total arterial pressure. An inference is drawn to the effect that the mounting perfusion pressure in the cerebral vessels following the action of reserpine and isobarine occurs as a result of their alpha-adrenoreceptors stimulation with norepinephrine that is intensively secreted from the nerve endings. Dopegit exerts an analogous action through formation of alpha-methyl-norepinephrine, which produces, like norepinephrine, an effect on the cerebral vessels.
