Stimulation of 3H-norepinephrine release by trifluoperazine from rat pineal glands.

abstract：:An acute injection of an intoxicating dose of alcohol to male rats 24 hours prior to breeding with drug-naive females produced no discernible effect on copulatory activity, as reflected in vaginal plugs, but resulted in markedly (> 50%) reduced pregnancy rates. Fetal outcome was also markedly affected in offspring sir...
