Choice of strong analgesic in terminal cancer: diamorphine or morphine?

abstract：:We studied whether striatal alpha(2)-adrenoceptors or N-methyl-d-aspartate (NMDA) receptors influence descending regulation of neuropathic hypersensitivity in the rat by microinjecting an alpha(2)-adrenoceptor agonist or NMDA-receptor antagonist into the dorsal striatum in animals with a spinal nerve ligation-induced ...

abstract：:Movement is changed in pain, but the mechanisms remain unclear. Key questions are unresolved such as whether activation can be inhomogeneously distributed within a muscle in a manner that is specific to the location of noxious input. This study addressed this question using high-density electromyography (EMG) to study...
