title: Circadian variations of gastrointestinal peptides and cell proliferation in rats: effects of adrenalectomy.
abstract: The hypothalamo-pituitary-adrenal axis appears to play an important role in regulating the circadian fluctuations of brain-gut peptides, as well as the cell cycle of the gastrointestinal mucosa. Since dexamethasone treatment tended to restore circadian fluctuations lost to adren-x, the influence of adrenal glucocorticoids in the coordination of the rhythms of regulatory peptides and cell cycle kinetics appears to be substantial.
