Changes in substance P and somatostatin in the spinal cord after traumatic spinal injury in the rat.

abstract：:In this study guinea pig, rat and bovine striatal extracts have been shown to contain putative opioid peptide precursors in the molecular weight (Mr) range 2000-greater than 70000. The material eluting greater than 70 kDalton contained bioassayable opioid activity but not Met- or Leu-enkephalin-like immunoreactivities...
