Experiments on rats showed that the selective opioid κ receptor agonist dynorphin A (1-13) had marked antioxidant actions in immobilization stress of different durations, apparent as reductions in lipid peroxidation products in liver tissues. The effects of this peptide on the activities of the antioxidant defense enzymes superoxide dismutase and catalase(More)
It was established in experiments on rats, that injection of opioid peptides DAGO (a selective igonist of opioid mu-receptors), DSLET (a selective agonist of opioid delta-receptors) or dynorpiin A (1-13) (a selective agonist of opioid kappa-receptors) decreased the stress-induced activatin of lipid peroxidation in liver tissue and plasma. A selective(More)
We compared changes in the liver structure in stress-resistant and stress-sensitive rats under conditions of chronic stress exposure. The number of degenerative cells, specific area of degenerative part of hepatocyte cytoplasm, and specific area of intralobular sinusoidal capillaries increased in animals of both groups. These parameters were significantly(More)
Experiments on rats showed that restraint stress is associated with an increase in plasma level of nonesterified fatty acids, total cholesterol, triglycerides, VLDL, and LDL. Administration of opioid peptides DSLET and DAGO alleviated stress-induced shifts in lipid metabolism. The concentrations of nonesterified fatty acids, total cholesterol, and(More)
Administration of opioid peptides dynorphin A (1-13) and DSLET was followed by a decrease in the stress-induced activation of LPO and increase in SOD activity in the liver tissue of rats. DAGO produced a similar, but less pronounced effect. The observed changes can be related to a specific distribution of opioid receptors in the liver tissue and(More)
