[Cytogenetic effects in peripheral blood lymphocytes in the offspring of Chernobyl nuclear power plant accident liquidators under the influence of mitomycin C in vitro and folic acid in vivo]

The data on cytogenetic examination concerning the offspring of the Chernobyl accident liquidators (cleanup personnel) have been obtained. It has been established that spontaneous chromosomal aberrations level before folic acid administration was 1,8 times higher than that value after its employment (4,45 to 2,42 %, p < 0,01). In lymphocyte cultures treated with mitomycin C accompanied by folic acid it was 4,5 times higher before their administration (23,95 to 5,36 %, p < 0,001). The data obtained confirm a possibility of stabilization of genetic apparatus in offspring of the Chernobyl disaster liquidators after folic acid administration.

[On diagnosis and prophylaxis of asthenoneurotic syndrome in cosmonauts in long-term mission]

Based on longer than 20 years experience of observation and investigation of the neuropsychic state of cosmonauts in long-term missions to the space stations and volunteers in ground studies of some of the spaceflight (SF) effects, principles of diagnostics, prophylaxis and correction of asthenoneurotic and psychoasthenic disorders in members of long-term orbital mission have been established. The authors give consideration to the most probable pathophysiological mechanisms of these disorders during SF and some potential lines of exploration and development of countermeasures against and methods for correction of the psychoneurologic disorders during long-term missions.

[Early diagnosis of neurotic disorders using an automated system]

The authors distinguish a complex of informative criteria of early diagnosis of neurotic disorders employed in the screening algorithm. The efficacy of the algorithm was evaluated in 285 patients with neurosis and the diagnosis proved correct in 93-95.2% of cases. The automatized system of screening of neurotic disorders ensures improvements in exact diagnosis, saves time and expenditures.
