[The micronuclei frequencies in the buccal cell epithelium of young people of different age and gender in Ukraine].
The results of study of micronuclei (MN) frequencies among the participants of Ukrainian school biological olympiads are presented. Totally 266 persons have been inspected. The distribution of MN frequencies correspond to the Poisson's distribution with lambda = 2.5. The average frequency of micronuclei in males was 2.4 +/- 0.15%, in females it was 2.7 +/- 0.14%. The difference of the average MN frequencies for these two groups was statistically insignificant. The individual micronuclei frequencies varied from 0 to 8.3%, the average MN frequency in the general group was 2.5 +/- 0.11%, (limits 2-5%). The micronuclei frequencies in different age groups of males and females were compared. Significantly higher MN frequencies in females than in males at the age of sixteen were detected. The age-related changes of micronuclei frequencies (14-18 age) were different for females compared to males.
