A comparison of opioid peptide precursors in guinea pig, rat and bovine striata and guinea pig adrenal.

abstract：:Recent studies have shown that oxytocin reduces food intake and body weight gain and promotes lipolysis in some species, including humans. Interestingly, these effects of oxytocin are more marked in obese individuals. Although the menopausal loss of ovarian function induces increased visceral adiposity and some metabo...
