EFFECTIVENESS OF ACTIVITY OF ANTIOXIDANT VITAMINOUS PREPARATION ON METABOLISM OF BONE TISSUE AT CHRONIC INTOXICATION BY THE DICHLOROETHANE DURING THE EXPERIMENT ^{[№ 12 ' 2010]}
Chronic (during two months) dayly intoxication by the dichloroethane in the cumulative doze of 0,1 LD50 of mature white rats causes strengthening the processes of free-radical oxidation, reduction in the activity of the ferments of antioxidant protection and increase in the content of free hydroxiprolin in homogenates of the epiphyses of tubular bones. In the plasma of the blood of experimental animals the level S-bodypeptids of a collagen of the type I repeatedly increases with the constant activity of bone alkaline phosphatase. The treatment of animals by vitamin preparation "Triovit" during three weeks at the dose of 50 mg/kg in a 24 hour period against the background to intoxication by dichloroethane renders positive therapeutic effect on the exchange of the bone, reducing the intensity of chemiluminescence, the accumulation of the primary and secondary products of lipoperoxidation, strengthening the activity of fermentation antioxidants, suppressing resorptive processes.

BONE MINERAL DENSITY DISTURBANCE IN MEN WORKING IN CHEMICAL MANUFACTUTE ^{[№ 9 ' 2008]}
Ultrasound densitometry of certain parts of skeleton (proximal phalanx of III finger, shin bone, spoke bone) of childbearing age men, working at chemical enterprises and having permanent contact with organic chlorine compounds (dichloroethane, 3-chlorine propene, 3-chlorine- 1,2-dihydropropane, trichloropropane, epichlorhydrin, etc.) revealed more frequent than in population spread of osteopenia and osteoporosis. It is shown, that early disturbance of bone metabolism is connected with activation of free-radical oxidation and change of hormonal status in the form of decrease of testosterones and increase of estradiol.
