AIM: To determine the activity of @entity224 dismutase, @entity7525 and the concentration of @entity1234 ( @entity1865 ) in @entity7462 , lens and red blood cells after application of @entity9809 ( @entity13102 ) into vitreous of @entity95 . MATERIAL AND METHODS: 0.5 ml of 100% SF6 was injected into the vitreous of 24 @entity95 of New Zealand race. The animals were randomly divided into 3 groups (of 8 @entity95 each) depending on the observation day: group 1-2nd day of experiment, group 2-7th day and group 3-14th observation day. The control group (gr. 0) consisted of 6 @entity95 that did not undergo any operations. Activity of @entity224 dismutase, @entity7525 and @entity1865 concentration were determined in @entity1503 . RESULTS: On the 7th day of observation an increased activity of dismutase and @entity7525 as well as simultaneous increased @entity1865 concentration were observed. In the lens on the 7th day the increased activity of dismutase was significant in relation to the results in the next time interval, whereas @entity1865 concentration was significantly lower in all time intervals of the experiment in comparison with control group. In erythrocytes an increased activity of @entity7525 was noticed on the 2nd and 14th day. CONCLUSIONS: Increased occurrence of active @entity26 species in @entity7462 leads to insufficiency of the antioxidant system and intensification of peroxidation processes, which is reflected by increased @entity1865 concentration. However, in the lens of this experimental model a slight stimulation of antioxidant system by a small number of free radicals is observed, which provokes a reaction of sweeping them away. Efficiency of lens antioxidant system is secured by weakening of peroxidation processes, which is expressed in minimal drop of @entity1865 concentration.
