[The content of double bonds and lipids in blood serum of healthy people and patients with hyperlipidemia].

The number of dual bonds (DB) was determined by the ozonization method in the lipid fraction of blood serm (BS) in healthy subjects and in patients with hyperlipidemia (HLP). Single-direction changes were detected in the DB quantity and in the lipid level in case of HLP; besides, a highly reliable positive correlation was established between the DB concentration and the basic BS lipid classes. The results suggest that an increasing DB quantity in HLP is preconditioned by a growing lipid contents and show their tense relation with components of the lipid transport system (LTS). The determination of the DB concentration, as of an index of the total unsaturation of the BS lipid fraction, provides for obtaining extra data useful in describing the LTS in different-type impairments of lipid metabolism.
