Abstract
A rat model of inflammatory and degenerative damages of the smooth parodont tissue by means of administration of 2 % formaldehyde water solution into the smooth parodont tissues was described. The oxidative status of rats including lipid peroxidation and antioxidant defense system indexes was assessed because of their high sensitivity to inflammation process. The lipid peroxidation indexes (malonic dialdehyde and dienic conjugates level) were 2-3-fold higher in the blood serum and parodont tissue in 7 days after inflammation beginning. The system of antioxidant defense (recovered glutatione level and activity of superoxide dismutase) was more sensitive in comparison with lipid peroxidation. The recovered glutation content in the blood serum was decreased from 2.02 ± 0.09 till 0.88 ± 0.21 µM/ml, and superoxide dismutase activity was reduced from 0.78 ± 0.10 till 0.28 ± 0.04 А/mg protein, that was these indexes were decreased in 2.5-3 times. The same regularity was observed in the smooth tissues of the parodont. The recovered glutation level was decreased in 2.1 times and superoxide dismutase activity was reduced in 7 times. Therefore, the curative and prevention action of tooth pastes and stomatologic drugs could be assessed with this model of inflammation. In particular, the tooth pastes lesmin-dent > clamin-dent > zhemchug (in order of descending activity) attenuate or abolish signs of inflammatory and degenerative damages of the smooth parodont tissue in rats assessed on lipid peroxidation and antioxidant defense system indexes.
