Sodium hypochlorite solution is an effective means in control of noncontagious aetiology diseases, accompanied by development of endogen intoxications. The detoxification action of sodium hypochlorite is that in the body there is no becomes free active oxygen, oxidizing there toxic and ballast substances as bilirubin, urea, ammonia, uric acid, creatinine, cholesterol, carbonic oxide, acetone, acetone acetate, ethanol, methanol, barbiturates, etc. The detoxification action of sodium hypochlorite is shown in neutralization of exotoxins and endotoxins of pathogenic microorganisms as it represents a compound of the small molecular mass and the small structural size. In this connection it freely gets through membranes of cells and oxidizes the toxins containing not only in blood, but also in cells. From this follows, that sodium hypochlorite models not only oxidizing function of cytochrome Р-450 of liver, but also phagocytal function of neutrophilic leucocyte. It leads to inactivation of large toxic molecular compounds both on a surface of uniform elements, and in blood plasma while effective methods reduce intoxication at the expense of removal of the average molecules circulating in plasma

Development of new selenium preparations in a complex with vitamins for the purpose of decrease of trace element toxicity and increase of its bioavailability is the topical problem of veterinary science. A new antioxidant water-soluble complex Aesel, which includes selenium as the activated product of interaction of methionine and sodium selenite, vitamins A and E, is researched. Lethal doses of the preparation for mice and rats were identified through intragastric and subcutaneous introduction. Due to the results of the research it was determined that Aesel is rated among the forth class of danger, so it is dangerous to a very little degree. Lethal doses of the preparation on the pure selenium, calculated on Pershin method, for rats at parenteral introduction is equal 5,48, at enteral introduction - 39, for mice at parenteral introduction - 7,72 mg/kg. Lethal doses of the preparation calculated on all making components equal to 39000 mg/kg.

There was studied the feature of hematological and biochemical blood indicators of rats at action of acute ionising radiation against acute stress influences. Results of research of hematological and biochemical blood indicators of rats developing under influence of stress and radiating factors are presented. It is established, that on 4 days twenty-four-hour period after the influence of pointed ionizing radiation against a background of pointed stress impact some changes become evident. They appear in reducing of total number of leucocytes, haemoglobin, hematocrit and general albumen, and also in increase of such ferment activity as lactate dehydrogenase, creatine phosphokinase, aspartate aminotransferase, alanine aminotransferase. | Целью исследования является изучение особенности гематологических и биохимических показателей крови крыс при действии острого ионизирующего излучения на фоне острого стрессорного воздействия. Представлены результаты исследования гематологических и биохимических показателей крови крыс, развивающихся под влиянием стрессорного и радиационного факторов. Установлено, что на 4 сутки после действия острого ионизирующего излучения на фоне острого стрессорного воздействия отмечаются изменения, выражающиеся в снижении общего количества лейкоцитов, гемоглобина, гематокрита и общего белка, а также увеличении активности ферментов лактатдегидрогеназы, креатинфосфокиназы, аспартатаминотрансферазы и аланинаминотрансферазы.
