The importance of vanillylmandelic acid determination in opiate users
Although knowledge about the etiology of heroin dependence is rather poor, it is known that the influence of opiates on the opioid, adrenergic and indirectly of GABA on the dopaminergic receptors leads to changes of catecholamine levels in brain structures, which are supposed to be essential in expl...
