[SUBSTANTIATION OF DOSE LIMITS FOR A NEW NORMATIVE DOCUMENT ON RADIATION SAFETY OF LONG-DURATION SPACE MISSIONS AT ORBIT ALTITUDES OF UP TO 500 KM].

Aviakosm Ekolog Med 2016 ;50(1):39-54

Review of the data of experimental radiobiology and epidemiological follow-up of large groups of people subjected to radiation exposures on Earth has been undertaken to substantiate dose limits for critical organs of cosmonauts in order to ensure good performance and vitality while on long-duration orbital missions. The career dose limits for cosmonauts and astronauts established earlier in the USSR and USA amounted to nothing more but banning the risk of cancer death increase to 3%. To apply more rigorous criteria of delayed radiation risks, the Russian limits for cosmonauts were revised to substantiate a 4-fold reduction of the average tissue equivalent dose maximum to 1 Sv.

[STUDIES OF THE ANTIHYPOXIC AND ANTIAMNESTIC EFFECTS OF MELATONIN IN ANIMALS].

Aviakosm Ekolog Med 2015 ;49(5):43-8

Experiments with mice showed that in a multitude of acute hypoxia models (normobaric hypoxic hypoxia with hypercapnia, hypobaric, hemic and histotaxic) the antihypoxic action of a single intra-abdominal dose of melatonin surpasses greatly amtisol, the standard antihypoxic agent. Single melatonin injection produced a strong antiamnestic action on various amnestic models (scopolamine-induced, acute normobaric hypoxia with hypercapnia, and a combination of extreme factors) which was much better than of pyracetame, a well-known nootropic (mind-stimulating) drug. Increase of the melatonin dose from 1 mg/kg to 20 mg/kg amplified both the antihypoxic and antiamnestic effects. Read More
