[Delayed medical consequences of the Chernobyl accident in Armenia. Assessment of life quality and accelerated biological aging of accident liquidators].

In this paper, some final results of 25-year investigations carried out in Scientific Centre for Radiation Medicine and Burns MH RA (SCRMB) on the Armenian cohort of the Chernobyl accident consequences liquidators are shown. These results show that health conditions of the liquidators became worse during the whole observation period. A considerable development of both pathological states atypical of radiation damages and diseases, which may be considered as radiation-induced ones, was determined.

[On the occasion of the 20th anniversary of the accident on the Chernobyl NPP: medical consequences in Armenia].

The aim of this work is the analysis of the indices of the health and of the structure of the sicknesses of the inhabitants of Armenia who took part in the liquidation of the consequences of the Chernobyl accident. Also it is the determination of possible dependence of the frequency of diseases for the most widespread classes of sicknesses on the received dose of the irradiation, according to the data of the clinical examination and dispensarysation; and also it is the revelation of the role of other factors influenced on the health indexes.

Clastogenic factors in the plasma of Chernobyl accident recovery workers: anticlastogenic effect of Ginkgo biloba extract.

Clastogenic factors are found in the plasma of persons irradiated accidentally or therapeutically. They persisted in the plasma of A-bomb survivors over 30 years. Clastogenic factors were found in 33 of 47 Chernobyl accident recovery workers (often referred to as liquidators) in a previous study (I.

Radiation-induced clastogenic factors: anticlastogenic effect of Ginkgo biloba extract.

Clastogenic factors (CFs) were first described in the blood of persons irradiated accidentally or for therapeutic reasons. Work of our laboratory has shown that they occur also under other circumstances, which are characterized by oxidative stress, and that CF-induced chromosome damage is regularly prevented by superoxide dismutase (SOD). Recently we found CFs in a high percentage of salvage personnel of the Chernobyl reactor accident.

[Results of a follow-up of participants in the liquidation of the effects of the Chernobyl AES accident].

The paper is concerned with the results of analysis of a clinico-laboratory study of persons (residents of Armenia) who took part in the elimination of the effects of the Chernobyl accident. Investigation of general morbidity revealed no correlation with exposure to ionizing radiation. The symptom complex of pathological changes included CNS functional disorders, a transition from the hypokinetic type of a heart response to exercise to the normokinetic one, lowered immune status and tissue peripheral blood flow, unmarked hematological and biochemical shifts, suggesting suppression of the body antioxidant system.
