... if nicotine, morphine and the serotonin 1A (5-HT 1A ) agonist 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) utilize a common synaptic pathway to release prolactin and, if so, to establish the serial order of the receptors involved. We also sought to determine whether the pathway under investigation leads...

..., caused an increase in plasma concentrations of LH and FSH, and antagonized the LH suppressory effect of morphine (10 mg/kg) administration. Despite this, naltrexone treatment was ineffective in preventing the inhibitory effect of chronic restraint stress on circulating LH and FSH. Chronic restraint also...

.... In the present study, we further evaluated the apparent universality of alterations in opiate-mediated function during the LH surge by investigating the effects of morphine sulfate (MS) on prolactin (PRL) secretion during both the estradiol benzoate (EB) and the EB + P4-induced LH surges. All doses of MS tested...

Thyroxine (T 4 ) levels were significantly reduced from 12 to 24 h after morphine, but triiodothyronine (T 3 ) levels were not affected. When...
