[The influence of tinofedrine on cerebral energy metabolism in normotensive, hypotensive and hypoxemic rats after carotis ligation (author's transl)].

l-(+)-alpha-(1-[(3,3-Di-3-thienylallyl)amino]-ethyl)-benzyl alcohol hydrochloride (tinofedrine hydrochloride, D 8955, Novocebrin), a new cerebrally active substance, synthetized in our research laboratories, was investigated for its action on the disturbed cerebral metabolism in rats. By variation of the arterial blood pressure (normal, 100 and 70 mmHg), and O2-concentration for the artificial ventilation of 30 or 15 vol% and carotis ligation for 15, 30 and 60 min different degrees of cerebral disturbances could be induced. The glucose concentration and energy state of the brain were used as criteria of the degree of cerebral disturbance. After intravenous injection of tinofedrine such a disturbed cerebral state could be normalized partially or completely.
