[Effectiveness of the use of synthetic opioid peptide in rats with traumatic shock].

Experiments were conducted on 80 male Wistar rats. Traumatic shock was simulated by applying clamps to lower extremity soft tissue for 6 hours. After removing the clamps, experimental animals were intraperitoneally injected the synthetic leucine-enkephalin dalargin. The blood ionogram, the levels of urea, glucose, phosphorus, creatinine, lactic and pyruvic acids, blood plasma osmolarity, LDH activity were determined. In the animals untreated with dalargin, plasma concentrations of ions of potassium, phosphorus, creatinine, urea, osmolarity, LDH activity increased and the levels of glucose decreased when shock developed. At the same time the rat death rates were 70-80% 24 hours later. The administration of dalargin corrected the majority of the above-mentioned parameters and the death rates were decreased to 20%. It is concluded that dalargin has an early antishock effect.
