Alteration of brain noradrenaline, dopamine and 5-hydroxytryptamine levels during vanadium poisoning.

Effects of subacute and chronic intoxication with vanadium on the levels of noradrenaline (NA), dopamine (DA) and 5-hydroxytryptamine (5-HT) were examined. It was shown that subacute as well as chronic intoxication caused changes in levels of biogenic amines in the rat brain. NA concentration decreased whereas DA and 5-HT levels significantly increased. Vanadium in concentrations of 10(-3) and 10(-4) M inhibited the uptake of 3H-NA by cerebral cortex slices in vitro.
