Prenatal phenobarbital treatment and temperature-controlling dopamine receptors.

Pregnant mice were fed a phenobarbital-containing diet on days nine through 18 of pregnancy. Following parturition, the offspring of such animals were allowed to reach adulthood and then were tested for their response to an acute injection of apomorphine. Male offspring were less sensitive, while female offspring were more sensitive than matched controls to apomorphine-induced hypothermia.

Amphetamine anorexia and hypothalamic catecholamines in genetically obese mice (obob).

Genetically obese mice (obob) and their lean littermates were acclimated to a restricted food-access schedule of six hours and then treated with various doses of amphetamine (0, 3, 5 or 10 mg/kg). Saline-treated obob mice maintained on this schedule retained the primary characteristics of obob mice fed ad lib, i.e.
