[Features of behavioral reactions of chronically irradiated mice in the raised crosswise labyrinth with various genetically determined radiosensitivity and possibilities of their modification by the fungal biopolymer complex].

Structural elements of the central nervous system--neurons, along with the higher neuroendocrine structures and the hypothalamus centres, show high sensitivity to a chronic action of low doses of ionizing radiation (IR) in view of their extreme enrichment by phospholipids and intensive supply by oxygen, creating favorable conditions for the development of oxidizing stress. Stressful influences cause negative emotions in the behaviour of animals manifested as fear or uneasiness. The study represents the results of comparative research into the behavioral reactions characterized by uneasiness in the Balb/c and C57bl/6 mice exposed to a chronic irradiation at low doses.

[Remote signaling of radiation damage to the extracellular space in mice with various levels of genetically determined radio sensitivity].

The search results of "bystander" signals are presented at different model of influence of IR on Balb/c and C57bl/6 mice, characterized by different levels of genetically determined sensitivity to IR influence. We used the following models of IR influence: 1) external gamma-quanta influence from small samples of nuclear fuel from the CNPP 4th power unit modified in the course of the accident in 1986, which are 99% connected with 137Cs, with the total dose of irradiation of about 5.0 Gy for 16 hours and accumulated dose of 0.

[Perspective for using chitin drugs in obstetrical practice].

The article focuses on structure, physical-and-chemical properties of chitin and glucans. An analysis was performed of experimental and clinical results of treatment with chitin and glucans. Shown in the paper is a high antibacterial activity of the drug mycoton.
