Abstract


The study was conducted to determine the neurohormonal mechanisms that underlie the clinical features of puberty onset in children born to parents exposed to low-dose irradiation. Hormonal homeostasis is assessed according to the data of immune-enzyme, radioimmune, and fluorometric methods. Statistical analysis of the data was carried out by means of the application package Excel and Statgrafics-5, SPSS 17.0. It has been established that the earlier puberty onset is caused by accelerated stimulation of pituitary-gonadal system due to activation of central mechanisms of pituitary gonadotrophic function regulation and eary reversal of melatonin blockage of this system. Reasonable basis has been suggested for careful clinical supervision over development of the reproductive system of the children from families with burdened radiation history.
