    Abstract:
    The experiments have been performed on 120 Wistar rats and 546 CBWH mice. Met-enkephalin (ME) and beta-endorphin (BE) levels were determined to increase in blood and mid-brain 3 hours later after soft tissue compression of pelvic extremities. 48 hours later after six-hour compression BE and ME level in blood was increased, BE concentration in blood was also increased, and enkephalins' content in brain and blood was decreased as against the control. Opioid peptides influence on the host compression period has been studied. D-agonists were established to decrease, but mu-agonists were established to increase mice survival in shock. Opioid peptides' significance in traumatic shock pathogenesis is being discussed.
