Abstract
- Some features of the chromosome apparatus status were studied in 25 adolescent girls, aged 14-18, with secondary amenorrhea and in 29 girls of the same age with a regular menstrual cycle. Materials for cytogenetic analysis were preparations of chromosomes at the stage of metaphase obtained from the culture of the peripheral blood lymphocytes. The technique of the culture preparation was carried out according to the standard method. 2225 metaphase plates were analyzed in girls with secondary amenorrhea, and 2603 plates were tested in their healthy age-mates. An increased total level of chromosomal aberrations and a rise in the frequency of disorders in the chromatid, chromosome and genome types of peripheral blood lymphocytes have been registered in the examined persons as compared with their healthy age-mates. We have shown, that polyploid cell registered in 15 times oftener in adolescent girls with SA as compared with healthy girls. It can be assumed that some marked changes in the frequency of chromosomal aberrations in patients with secondary amenorrhea and in their healthy age-mates may arise both as a result of exposure to the multiple environmental factors and disorders of rather complicated processes of DNA damages reparation.
