ВЛИЯНИЕ ПЕПТИДНОГО КОМПЛЕКСА ИЗ ТКАНЕЙ СВИНЫХ ПОЧЕК НА ПОКАЗАТЕЛИ СВОБОДНОРАДИКАЛЬНОГО ОКИСЛЕНИЯ И ЭКСПРЕССИЮ ЦОГ-1,2 ПРИ ИНДОМЕТАЦИН-ИНДУЦИРОВАННОЙ ГАСТРОПАТИИ

The aim was to investigate the influence of the peptide complex from pork kidney tissues on indicators of free radical oxidation and the expression of COX-1,2 in experimental Indometacine-induced gastropathy. Materials and methods: There were examined 67 male Wistar rats. Experimental peptic ulcer disease was reached by the injection into the stomach of 60mg/kg Indometacine. The experimental group had got 75mg/kg for 7 days up to the Indometacine injection. The concentration of enzymes COX-1, 2 in blood plasma and gastric homogenate were determined by the method of enzyme immunoassay. The activity of free radical oxidization processes was evaluated by the coloring intensity of the products of the corresponding biochemical reactions. Results: In the experimental group the concentration of COX-2 in the gastric mucosa was reduced by 26.5% comparing to the intact group. Thiobarbituric acid-reactive substances concentration was redused in 2,3 times comparing to the control group. Increased under the effect of indomethacin, the concentrations of superoxide dismutase and glutathione peroxidase were equal the concentrations of healthy rats. Conclusion: The injection of a peptide complex from pork kidney tissues for 7 days is accompanied by reducing of the inflammatory process in the gastric mucosa, as evidenced by a decrease in the concentration of COX-2 in the stomach homogenate, as well as reducing of oxidative damage to gastric cells and strengthening their enzyme antioxidant protection.
