Dynamics of changes in cadmium levels in environmental objects and its impact on the bio-elemental composition of living organisms.

As a result of intensive anthropogenic impact in the biosphere there is a rapid process of accumulation of heavy metal salts. They have led to the aggravation of problems associated with the pollution of ecosystems and basic food products of plant and animal origin. Environmental pollution by these compounds is caused by their persistence in environmental objects, migration ability, accumulation by plants.

[Effect of phospholipids containing omega-3 fatty acids on structural changes of microsomal lipids in cell membranes of functionally different cells].

As a result of the experimental researches conducted it has been shown that administration of some normal animal marine phospholipids (PL) including in their structure omega-3 polyunsaturated fatty acids (PUFA) provides for quantitative changes of individual PL, fatty acids (FA) content and quantity in general and individual PL of liver, heart, brain and gonads microsomes. While estimating general microsomal PL fraction FA content under the action of PL omega-3 PUFA FA concentration change, unsaturation index (omega 6/omega 3) and relation of arachidonic acid to docosahexenic (AA/DHA) decrease have been identified. The decrease of AA/DHA relationship occurs due to AA and DHA quantitative changes.

[Specificity of endometrium phospholipids and their fatty acids changes in the development of hyperplasia].

Quantitative changes in phospholipids (PL) and fatty acids content (FA) in patients with endometrium hyperplasia have been revealed. During observing endomentrium hyperplasia process we found out on the one hand reliable decrease in phosphatidylethanolamine (PEA), phosphatidylcholine (PC) content and on the other hand increase of its lysoforms. Changes in unsaturated fatty acids (PA n-6)--arachidonic (AA) content and docosahaenoic (DHA) acids content were also shown.
