abstract：:Utilizing a double-blind crossover design, the hormonal effects of high dose, 2 mg/kg, were compared to low dose, 0.4 mg (approx. 5 micrograms/kg), naloxone administration in physically healthy humans. A significant naloxone dose effect on plasma cortisol levels was found (p less than 0.001), but no significant effect...

abstract：:Immunoreactive substance P (SPI) and somatostatin (SOMI) are found in spinal cord but their physiological roles remain speculative. Several classes of neuropeptides, including endogenous opioids and thyrotropin-releasing hormone (TRH), have been implicated in the pathogenesis or recovery from spinal cord injury. In th...
