Neuropharmacological actions of the superactive agonist analog D-TRP-6-LH-RH after peripheral injection into mice.

abstract：:The role of somatostatin and a stable analogue, sandostatin (Octreotide), on the responses of spinal cord neurones in vivo was investigated in the rat. Electrical C-fibre stimulation was used as a model of acute nociception and the response to subcutaneous formalin was used as a model of longer term events. Intratheca...

abstract：BACKGROUND:Chromogranin A (CgA) in plasma (P-CgA), a neuroendocrine marker of sympathetic stress, has been shown to predict mortality in medical intensive care. We hypothesized that the magnitude of CgA release would reflect stress load, and thereby injury severity in burn intensive care patients. METHODS:Fifty-one co...
