title: [Effect of thiamine bromide on cerebral circulation and arterial pressure (an experimental and clinical study)].
abstract: The effect of thiamine-bromide (5-7 mg/kg, intravenously) on the cerebral blood flow circulation rate; total arterial pressure, oxygen tension in the brain tissues (measured polarographically) and pressure in the venous vessels of the brain was investigated on anesthetized cats with controlled respiration. In patients with hypertensive disease (essential hypertension) the action of the agent (1 ml of a 6% solution, intramuscularly) on the rheoencephalographic readings and overall arterial pressure was studied. Thiamine-bromide is shown to lower the tonicity of intra- and extracranial vessels and to increase pulsed variations in the volume of blood filling of the cranial vessels. The hypotensive effect of the drug is pronounced but mildly. The oxygen tension in cerebral vessels depended mainly on changes in the cerebral circulation rate.
