Influence of antioxidant effect of stobadine derivative in condition of kidney ischemia-reperfusion in a pre-clinical experiment (effect in therapy).

ABSTRACT

The goal of the study was to monitor the antioxidative effect of stobadine derivative under conditions of ischemia-reperfusion of laboratory rat kidney tissue. 40 animals were subjected to kidney tissue ischemia (60 min) followed by reperfusion (10 min). After that, the animals were divided by random selection into 4 groups (n = 10). The treated groups were given stobadine derivative in peroral doses of 5, 10 and 20 mg/kg in 0.5% solution of Avicel once a day, the placebo group was given only the solution of Avicel. One group (n = 10) was an intact group (without ischemia-reperfusion and without treatment), for comparison. Once a week, selected laboratory parameters were determined in all animals. On the 15th day the animals were exsanquined and organs were recovered for histopathological examination. We discovered a statistically significant changes of the superoxiddismutase and glutathione peroxidase catalytic activity; changes of total antioxidative capacity and malondialdehyde in the treated groups compared to the groups of placebo and intact. Other examined laboratory parameters (creatinine, urea and uric acid in blood; creatinine, urea, total protein in urine; diuresis) exhibited significant changes too. The results of biochemical examination show a protective antioxidative effect of the compound studied. The results of histopathological examination support this assumption.
