Abstract: The aim of study was to investigate an influence of nutritional
deficiency and dietary addition of vit. B_{2},
B_{6} and folic acid on PUFAs content in rats' serum and
liver. Limitation of consumption full value diet to 50% of its previously
determined daily consumption, enriched with m/a vitamins, significant decreased
of linoleic (LA) and α-linolenic (ALA) acids as well as distinctly
increased arachidonic (AA) and docosahexaenoic (DHA) acids content in serum in
30^{th} day. In 60^{th} day lower content
of AA and DHA fatty acids was found. Nutrition with such diet, lasting 90 days
caused decrease of LA content and increase of AA. Diet limitation to its 30% of
daily consumption decreased of eicosapentaenoic acid (EPA) and DHA in the
30^{th} day, while AA and DHA content was increased in the
60^{th} day. Distinct decrease of AA content and increase of
EPA content were found in the 90^{th} day of experiment. Use
of diets, with limited consumption to 50% caused increase of LA and ALA acids
content while AA and DHA acids content were significantly decreased in the
liver, in 90^{th} day. Limited consumption supplemented diet
to 30% caused in liver significant decrease of LA and increase of EPA acids
content.
