title: [Effect of promedol and fentanyl on the permeability of the hemato-encephalic barrier of rats for noradrenaline-H3].
abstract: In tests situations with rats it was shown that promedol and phentanide produce an analgetic action accompanied by a reduced flow of tagged norepinephrine from the blood into the brain. A parallelism between the dosage of the substances and the intensity of the analgetic effect and the degree of changed permeability of the blood-cerebral barrier could be noted.
