title: Sympathetic and adrenocorticoid influences on diet-induced thermogenesis and brown fat activity in the rat.
abstract: Bilateral adrenalectomy markedly reduced body weight and energy gain and energetic efficiency of adult cafeteria-fed rats but enhanced the thermogenic response to food and stimulated brown fat activity. These changes were totally prevented by replacement of the animals with corticosterone (1 mg/rat/day). Unilateral denervation of the sympathetic nerves supplying the interscapular brown adipose tissue abolished the enhanced activity resulting from adrenalectomy and inhibited thermogenic activity in brown fat from cafeteria rats with intact adrenals, but had no effect in adrenalectomised animals treated with a high dose of corticosterone.
