title: [The effect of nimodipine and verapamil on the blood supply and vascular reactivity of the brain].
abstract: In experiments on conscious rabbits with electrodes implanted into the brain it was found by using hydrogen clearance method that nimodipine (0.1-0.06 mg/kg) and verapamil (0.3-1 mg/kg) increase the local blood flow to the decreasing degree in the cerebral hemispheric cortex, hypothalamus and thalamus. This is associated with a decrease in reactivity of the vessels of the above mentioned brain structures determined by the dilatory reaction to the dosed inhalation of carbon dioxide.
