In the experiments on 120 rats with experimental “peroxide” stomatitis the influence of tooth elixirs, containing bioactive substances on the activity of catalase antioxidant ferment and concentration of malonic dialdehyde (MDA), that is the index of processes of lipids peroxidation (LPO), was determined. The development of stomatitis was found out to cause the rise of concentration of MDA and suppression of activity of catalase in blood serum. The use of tooth elixirs influences positively these indices. To estimate the state of peroxidant and antioxidant systems of organism is most possible through correlation of activity of catalase and concentration of MDA (index API).
