...Carlos M. Villegas-Gabutti; Gisela E. Pennacchio; Laura Vivas; Graciela A. Jahn; Marta Soaje Background/Aims: During late pregnancy, the blockade of progesterone action by mifepristone (Mp) treatment induces a dopaminergic tone fall that enables naloxone (NAL) administration to release pituitary...

...) in ovariectomized rats. However, the mechanisms underlying this action remain unclear. We examined the effects of naloxone (NAL), a specific opioid antagonist, on the suppression of pulsatile LH secretion by ghrelin to determine whether β-endorphin (β-END) is involved in this suppressive effect. Methods: Ghrelin...

In 6 normal subjects, basal ACTH and cortisol plasma levels were significantly suppressed 3 h after loperamide administration (16 mg, orally) from 5 ± 0 to 2 ± 0 pmol/l and from 356 ± 44 to 154 ± 16 nmol/l. After stimulation with 8 ng ceruletide/kg...

Administration of naloxone, an opioid receptor antagonist, at a rate of 1.0 mg/kg/h for 2 h resulted in shorter (p < 0.05) intervals between MUA volleys than during the control period (61.6 ± 0.7 vs. 92.5 ± 7.2 min) in animals treated with progesterone and estradiol...
