Hormonal activity of the sera was studied immediately after blood collection and 6 months, one year and 1.5 years following their storage at a temperature of -20 to 25 degrees C in 10 healthy males aged 18 to 20 years. It was found that differently directed changes in immunologic activity of blood serum hormones took place on long-term storage at low temperatures. The data obtained suggest that the adrenocorticotropic hormone, immunoreactive insulin, protein-bound iodine and follicle-stimulating hormone retain the immunologic activity not more than one year, while the hormone, stimulating interstitial cells, thyrotrophic hormone, somatotrophic hormone, 17-HOCS, testosterone and aldosterone up to 1-1.5 years. During this storage of frozen biosubstrates the recurrent freezing out that produces changes in the immunologic activity of some hormones should be excluded.

[Estimation of soil fraction of Pu in the formation of irradiation dose of inhabitants of the Bryansk region].

The estimation of plutonium in soils of the contaminated after Chernobyl accident areas of Bryansk Region (Russia) are presented. On the basis of data about Pu concentrations in soils and by means of migration models in "soil-man" system the doses received were assessed. Pu-239, 240 and Pu-238 were determined in samples of autopsy material (lung, liver, bones and tracheobronchial lymph nodes) of residents from Chernobyl-fallout contaminated regions. Effective doses have been obtained by means of data about Pu-concentration in autopsy samples.
