the effect of ethanol ( 3.9-390 mm ) on resting tension of vas deferens , isometric contractions produced by field stimulation of the vas deferens and on the contractions produced by neurotransmitters , acetylcholine ( ach 0.55-55 mm ) , noradrenaline ( na 0.058-580 microm ) and 5-hydroxytryptamine ( 5-ht 0.25-250 microm ) was studied in rat vas deferens to see if ethanol modified neurotransmission and muscle contraction in this preparation .
