- Аннотация: Gas chromatography with mass spectroscopy detection have shown that the major components of atheromatous masses in formed atherosclerotic plaques (surgery material) are the derivatives of essential polyenic fatty acids (ES poly-FA) and of the alcohol cholesterol. They undergo nonphysiological catabolism (hydrolysis) in the lysosomes of resident macrophages as components of protein macromolecules, low-density lipoproteins (LDL). In excess of palmitic triglycer- ides apoB-100 of LDL does not form ligand, and ligand-free LDL become biological <rubbish> in the circulation. They are uptaken via scavenger receptors by resident macrophages in the intima. When ligand LDL are physiologically uptaken via apoB-receptors, they are catabolized (oxidized) in peroxisomes but not in lysosomes. Lipid spots result from functional cellular lipoidosis which fulfills the biological reaction of inflammation and initiate the lipoidosis--vector protein for FA transport--C-reactive protein pathway. Formation of ligand-free LDL lays the basis for intracellular ES poly-FA deficiency and clinical manifestations of the atherosclerosis syndrome. Intima is the spot where large-molecular-weight (> 70 kD) biological rubbish is collected and utilized from a local intravascular pool of the intercellular medium.
