[Adrenergic component in the mechanism of action of sodium oxybutyrate].

The influence of sodium oxybutyrate on the adrenergic neurotransmitter content in the nerve fibers and the synaptic vesicles and the uptake of exogenous noradrenaline (NA) by the sympathetic nerves of rat Vas deferens was studied by spectrofluorimetry, fluorescent-histochemistry and cytochemical electron microscopy. Sodium oxybutirate failed to influence the stores of the adrenergic mediator, but was capable of blocking the uptake and accumulation of the exogenous NA.
