[Levels of XXXX in the hypothalamus, hypophysis and in the adrenal in @entity742 after whole-body exposure to gamma rays].

@entity3034 @entity742 @entity935 @entity1425 @entity2339 @entity2661 @entity1063
The changes were studied in the levels of @entity2661 and @entity3034 in the control system of reproduction cycle (hypothalamus, hypophysis) and in adrenal glands of @entity742 after all-body irradiation with 60Co at the total dose of 6.7 Gy for seven days. The power input per hour of irradiation source was 0.039 Gy. The @entity2661 ( @entity1063 , @entity935 and @entity1425 ) and @entity3034 were determined, after having been isolated from the tissues, by the method of spectral fluorimetry. After all-body exposition to gamma-radiation @entity1063 dropped in hypothalamus in comparison with the control group of @entity742 , most significantly in the rostral (by 74.2%) and caudal part (by 40%). A similar drop like in the case of @entity1063 was also observed in @entity935 , the concentrations of which decreased in @entity2339 by 72%, in medial hypothalamus by 94% and in @entity2339 by 60%. @entity1425 shows a drop in hypothalamus, most significant in caudal region (by 62%). In relation with that the level of a precursor for the synthesis of @entity2661 and @entity3034 has been changed which achieved, in the studied regions of hypothalamus in @entity742 , significantly lower levels than were determined in the control group of @entity742 . As regards the hypophysis, after irradiation no significant changes in the levels of @entity1063 and @entity1425 were recorded, however, @entity935 and @entity3034 dropped significantly (P less than 0.01). The exposition to gamma-radiation also causes a decrease in the concentrations of @entity2661 and @entity3034 in the adrenal glands of @entity742 , most significant in @entity1063 (by 61%).(ABSTRACT TRUNCATED AT 250 WORDS)
