[Haemopoiesis-stimulating and radiomodifying effects of a preparation from a plant Chamaenerion angustifolium].

The experiments as conducted in mice revealed radioprotective therapeutic effect of a preparation made from a plant Chamaenerion angustifolium. The preparation per oral administration in the course of 4 to 8 days post radiation at a dose range of 7.2 to 10.

[Grounds for using cattle as one of reference organisms in the system of environmental protection from radiation].

Taking into consideration the basic principles of environmental protection from radiation as stated in Publication 91 of the International Commission on Radiation Protection (ICRP), we suggest cattle to be included into fauna reference species group. The choice is based upon cattle being a typical representative of specific ecosystems and may serve as an informative biological indicator and comparable with humans for its susceptibility to radiation effects. Cattle will receive some higher radiation doses as compared to humans due to its habitat, also earlier determined physiological and radiation constants for cattle are available.

[The efficiency of ferrocin application in rats at strong stressor exposures].

The influence of ferrocine to transfer of the 137Cs from gastrointestinal tract to organs and tissues of rats in conditions of strong stressor exposures was investigated. It is established that mechanical, cold and locomotor exposures reduce the ferrocine application efficacy.

[An assessment of the absorbed doses in cattle over the course of the first year after the accident at the Chernobyl Atomic Electric Power Station].

Absorbed doses of incorporated iodine and caesium radionuclides were evaluated in cattle animals which were within the Chernobyl accident spilling-out zone during the first year after the accident. The absorbed doses in animal thyroids were determined to range from 25 to 320 Gy. Some endemic features of this region promoted high absorbed dose accumulation in cattle thyroid.

[The use of ferrocyanides for obtaining pure meat production in contaminated areas following the accident at the Chernobyl Atomic Electric Power Station].

The paper reports a new technique of obtaining radioactive Cs-free meat in the regions contaminated with radionuclides as a result of Chernobyl accident. The method is based on specific digestion features of ruminant animals. Ferriferrocyanide compounds are proposed as sorbents.
