[Lipid fatty acid composition of the blood and organs in experimental and enteral feeding].

The rats which received intravenous nutrition (polyamine, glucose, intralipid) for 9 days showed a decrease in the proportion of palmitic and oleic acid, an increase in the content of polyunsaturated fatty acids in blood serum lipids, as well as a lowering of the proportion of arachidonic acid in liver lipids. The fatty acid content of platelet and splenic lipids remained unchanged. In dogs which were given fat emulsion enterally, intraportally or into the common blood circle in addition to the diet for 3 weeks, the changes in the fatty content of blood serum lipids were most marked upon enteral route of administration.
