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

The goal of the study was to monitor the antioxidative effect of stobadine derivative in the conditions of ischemia-reperfusion of laboratory rat kidney tissue. The animals were divided by random selection into 5 groups (n = 10). The treated groups were given stobadine derivate 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. The last group was an intact group (without ischemia-reperfusion and without treatment). After conclusion of medication on the 15th day all animals were subjected to kidney tissue ischemia (60 min.) followed by reperfusion (10 min.). All animals were subsequently exsanquined and single identification of superoxiddismutase, glutathion peroxidase, total antioxidative capacity, and malondialdehyde level in the blood were determined. Kidneys were recovered for histopathological examination. A statistically significant decrease of the superoxiddismutase and statistically significant increase of the glutathione peroxidase catalytic activity in the treated groups compared to the groups of placebo and intact was discovered. There was also a statistically highly significant increase of total antioxidative capacity in the treated groups compared to the groups of placebo and intact. A statistically significant decrease of malondialdehyde level was identified in the treated groups compared to the groups of placebo and intact. The results of biochemical examination show a protective antioxidative effect of stobadine derivative. The results of histopathological examination support this assumption.
