The fatty acid composition of muscle lipids may show quantitative alterations in diseased muscle. Thus lecithin isolated from human dystrophic muscle had an increased amount of oleic but diminished linoleic acid (Tl). Changes have been recorded also in the fatty acid composition of lecithin from denervated muscle (PI). Recently it has been reported (K16) that the fatty acid pattern of muscle phosphatides from patients with the autosomal dominant form of myotonia congenita differed markedly from that of the autosomal recessive form and from the normal. Tani and his co-workers (F7) have made a detailed study of the phospholipids of normal and dystrophic mouse tissues. In normal mice phosphatidylcholine and phosphatidylethanolamine from skeletal and heart muscles had a very high content of 20-22-carbon polyunsaturated acids, in comparison with those for other tissues the most abundant was docosahexaenoic acid. In dystrophic mice there was a sharp decrease in the proportion of docosahexaenoic acid in the phosphoglycerides from skeletal and heart muscles, suggesting the likelihood of important alterations in muscle membranes. Somewhat similar studies have been reported by Owens (05), who also observed a fall in the proportion of docosahexaenoic acid, mainly in the phosphatidylcholine -j- choline plasmalogen fraction.

General experience in increasing the n-3 lipids contents of eggs and poultry meat includes the following. The feeding of linseed oil, menhaden oil, and soybean oil to chickens has resulted in similar blood plasmas with VLDL and LDL lower than those fed chicken fat. The levels of C20 5n-3 in tissue lipids of chickens fed linseed oil approached those of chickens fed menhaden oil. Chickens fed linseed oil had the highest levels of polyunsaturates in tissues while those fed chicken fat had the lowest. Chickens fed soybean oil maintained the highest levels of linoleic (C18 2n-6) and arachidonic (C20 4n-6) acids in tissue lipids, but linseed oil and menhaden oil resulted in reduced C20 4n-6 content (112). Other researchers have also reported similar decreases in arachidonic acid, and increased levels of eicosapentaenoic (C20 5 -3) and docosahexaenoic (C22 6n-3) in the fatty acids of egg yolks from chickens fed menhaden oil (113-116).
