ABSTRACT
Ultrastructural and metabolic changes were studied during chronic fluorine intoxication and low doses of radiation (total dose is 1 Gr) in liver cells and tissues in rats fed with amaranth oil and treated with intermittent hypoxic training (IHT). The obtained data detected the ordered and compact position of mitochondria, peroxisomes, lipoprotein droplets with light electronic density, glycogen granules and also agranular endoplasmatic retuculum channels, which may be linked with reorganization of metabolic pathway of energy supply from fat acids via gluconeogenesis. Simultaneously the decrease of TBA-reactive substances accumulation with the considerable increase in activity of the antioxidant enzymes (catalase, glutathione peroxidase) and index of general antioxidant activity have been established. Therefore, the combined effect of IHT and amaranth oil on adequate occurence of free radical reactions provides the effective adaptation of organism to fluorine intoxication and ionizing radiation via the restoration of homeostasis on metabolic and ultrastructural levels. The obtained results allow to recommend IHT and amaranth oil for complex correction of changes, induced by fluorine intoxication and ionizing radiation.

Lipid peroxidation and antioxidative defence system in blood, liver and heart tissues, nitric oxide metabolites content in brain tissue of rats under binary action of small-doses of ionizing radiation and fluoride intoxication treated by amaranth oil and interval hypoxic training have been studied. Complex using of amaranth oil and interval hypoxic training result in increase both enzymatic, as nonezymatic links of antioxidant defence in all investigated tissues. It was revealed also enhance of NO system metabolites content in brain gomogenate. In this conditions lipid peroxidation processes in liver and heart tissues normalize comparison with essential increase level LPO under binary action influence. On the basis of obtained results LPO metabolites content we can suppossed that complex using of amaranth oil and interval hypoxic training result in increase of organism adaptative possibility. This complex can be using for binary action of ionizing radiation and fluoride intoxication correction.
