title: [The role of dopamine in regulating the cerebral circulation in extreme conditions].
abstract: In acute experiments on anesthetized cats, the perfusion of dopamine (100 micrograms/kg.min) during 35 minutes after cerebral ischemia inhibited the development of postischemic phenomena. Dopamine was found to exert a considerable effect on the oxidative metabolism in the brain. The responses of cerebral, peripheral vessels and systemic arterial pressure to dopamine (25 and 75 micrograms/kg) in conditions of blood autoperfusion with cooled blood did not differ significantly from those in normothermia. The problem of dopamine participation in the organism adaptive responses to extreme conditions, is discussed.
