abstract：:In the isolated guinea pig vas deferens, 10(-4) M cocaine shifts to the left (13.5-fold at the EC50 level) the concentration-effect curve and increases the maximum response to noradrenaline, whilst supersensitivity to phenylephrine, an amine with a low affinity for the neuronal uptake, was smaller (4.1-fold) and the m...

abstract：:In rats with lymphostatic encephalopathy the duration of harmine tremor was lengthened, and the brain concentrations of harmine decreased more slowly than in sham-operated controls. The tremor began simultaneously in both rat groups at coinciding brain concentrations of harmine. In rats with lymphostatic encephalopath...

abstract：:In anesthetized rats intravenously infused, norepinephrine (NE) was accumulated by the heart, the spleen and the lung in a dose-related manner. With the lower dose of NE (2.5 mg/kg) the organ/blood ratios were more than unity and were generally greater than with higher doses (5 and 10 mg/kg), indicating that accumulat...
