Summary

Contrary to prediction, loading rats with tryptamine, tryptophan or methanol failed to produce any rise in endogenous monoamine oxidase inhibitor output, whilst ethanol administration resulted in a significantly decreased excretion. These findings, which provide no support for the hypothesis that the inhibitor is aβ-carboline, may shed some light on the tranquillizing effect of ethanol in man.
