[Study of arteriosclerosis in different geographical zones of the Soviet Union. 3. Fatty acid composition of blood serum lipid fractions in Tashkent population].

The composition of fatty acids in triglycerides and cholesterol ethers of blood serum was studied in 90 normal males, Russians and Uzbeks, aged 20 to 50 years, living in the city of Tashkent. The peculiarity of the tryglycerides fraction in indigenous Tashkent inhabitants consists in a high content of linoleic acid. (24.8%). This is attributed to the peculiarities of nutrition of the indigenous Uzbekistan population--a consumption of great amounts of cotton-seed oil rich in linoleic acid. With the growing age, the content of the linoleic acid in the cholesterol ethers decreases, and the portion of palmitic and oleic acids growing. Among indigenous. Tashkent residents, aged 20-29 years, the relative content of the linoleic acid in the cholesterol ether fraction is higher than among the non-indigenous residents of the same age-group.
