| description | Background
Fluorine influences many processes occurring in the organism. Controversies over the evaluation of the biological
effects of this substance are due to a small difference between tolerable and toxic fluorine doses. One of the main mechanisms
of the fluorine toxic action is its ability to induce oxidative stress via reactive oxygen species generation and antioxidant
defense system impairment. It is important to evaluate possible interactions between fluorine and other substances
that may increase or decrease its toxicity.
Material and Methods
The study lasted for 35 days. Twenty-four rats were divided
into 4 groups: the control, with sodium fluoride (NaF) in the diet, with sodium fluoride, methionine and vitamin E (NaF+M+E)
in the diet, with sodium fluoride and vitamin E (NaF+E) in the diet. The biochemical analysis conducted in animal liver homogenates
included determination of activities of: total superoxide dismutase (t-SOD), superoxide dismutase with copper and
zinc (CuZnSOD), superoxide dismutase with manganese (MnSOD), glutathione peroxidase (GPX), catalase (CAT), glutathione
reductase (GR), glutathione S-transferase (GST) and the malondialdehyde (MDA) concentration.
Results
The activities of CuZn-
SOD, GPX, CAT and MDA concentration were changed significantly. There were no differences in the activities of t-SOD,
MnSOD, GR and GST among the experiment.
Conclusions
In the conducted experiment, the run-out of enzymatic protection of
liver by decreasing of the activities of antioxidant enzymes (CAT and GPX) and increasing the MDA concentration in NaF group
was observed. The addition of vitamin E and methionine does not significantly stimulate the enzymatic antioxidant system, however,
it causes of MDA concentration decreases. Med Pr 2018;69(4):403–412 |
