Serotonin (5-hydroxytryptamine) and beta-endorphin administered into the third ventricle of the hen blocked normal and progesterone-induced ovulation, and suppressed the release of LH in normal and progesterone-injected hens. p-Chlorophenylalanine, an inhibitor of serotonin synthesis, caused the release of LH and diminished the effect of beta-endorphin. Naloxone, an antagonist of opiate peptides, diminished the effect of beta-endorphin but not the effect of serotonin. The results suggest that… CONTINUE READING
