title: [Effect of myelopeptides on physiological and pathological pain].
abstract: The action of bone marrow low-molecular peptides (myelopeptides) was studied in the models of physiologic and pathologic pain. Myelopeptides were demonstrated to have a pronounced analgetic effect: they increased the latent period of the rats' response in the hot plate test (physiologic pain) and suppressed severe spinal pain syndrome induced by the generator of pathologically enhanced excitation in the dorsal horn of the spinal cord (pathologic pain). In the experiments with naloxone (an opiate receptor blocker) the data on the opiate properties of myelopeptides were further substantiated. The analgetic effect of myelopeptides can be compared to that of morphine and promedol. Myelopeptides even in considerable doses did not have the side effects characteristic of the majority of opiate analgesics. Therefore, they may be recommended for clinical trials.
