[Effect of "marine" phospholipids omega-3 fatty acids on the composition of fatty acids of rat liver microsomal membrane under oxidative stress]. / Vplyv "mors'kykh" fosfolipidiv z omega-3 zhyrnymy kyslotami na sklad zhyrnykh kyslot mikrosomal'nykh membran pechinky shchuriv za okysliuval'noho stresu.

As a result of experiments conducted the marine phospholipids preparation enriched by omega-3 fatty acids was defined to modify fatty acids content due to changes of fatty acids level change in the neutral lipids and phospholipids fractions. As well it was identified, that at the oxidative stress induced by administration of CCl4 the growth of arachidonic and docozahexaenoic acids in the neutral lipids fractions was observed if compare with the norm. At the same time, the presented fatty acids in the phospholipids fractions remained unchanged. At oxidative stress the phospholipids fraction reacts to levels of arachidonic and docozahexaenoic acids just only as a result of administrating phospholipids with omega-3 fatty acids. The most attractive is the change of correlation C20:4/C22:6--increasing at administration of CCl4 and decreasing both at phospolipids and vitamin E injection. Thus, at the oxidative stress the first reacting ones are the fatty acids of neutral lipids microsomal membranes.
