Effects of ethanol ingestion on alpha‐adrenoceptor‐mediated circulatory responses in man.

Normal male subjects (n=8 for noradrenaline and methoxamine infusion studies, n=6 for lower body negative pressure studies)

Acute ethanol consumption (1.0 ml/kg, 20% v/v, in orange juice)

Equivalent volume of orange juice (crossover design where each subject acted as his own control)
