[The study of the frequency of buccal epithelium cells with nuclear in athletes in dependence on the place got in the competition].

Cytogenetic homeostasis ofathletes involved in hand-to-hand armyfighting, depending on the outcome of the fight and the level of aggressiveness has been studied. Status of the genetic apparatus in athletes was evaluated in buccal epithelium with the use of micronucleus test, which is widely usedfor the determination of the influence of various factors on the genetic stability of the organism. Psychological testing of athletes was executed with the use of Spielberger’s State-Trait Anger Expression Inventory scale, Bass-Darky questionnaire for the diagnostics of aggression and hostile reactions, Eysenck Personality Questionnaire test for the evaluation ofpsychic conditions and method of U.P. Ilyin and P.A. Kovalev for the identification of the propensity to conflictness and aggressiveness (positive and negative) as the personal characteristics. The place taken by the athlete on the competition was shown to have an impact on the frequency of buccal epithelium cells with nuclear abnormalities (micronuclei, perinuclear vacuoles, notches, protrusions "tongue" and "broken egg”). Losers have nuclear aberrations more than winners. At that in athletes with higher aggressiveness and its attendant psychological characteristics the influence of the outcome of the competition on the number of cells with aberrations core is more pronounced.
