[Content of nicotinamide coenzymes, metabolites and the NAD-dependent dehydrogenase activity in the blood in arteriosclerosis].
Study of the key mechanisms, metabolism regulators, showed that in the blood of patients with atherosclerosis the NAD/NAD . N ratio decreases by 59.8% and the NAD+ concentration by 44%, while the NAD . N content increases by 56.7%. In the nicotinamide adenine dinucleotide system there is a general tendency tomards accumulation:the concentration of NADP+ grows by 218.6% and that of NADP . N by 12.9%. A marked increase in the content of incompletely oxidized products is determined: lactic acid by 37.4%, alpha-glycerophosphate by 49.8%, dihydroxyacetone phosphate by 155%, oxaloacetate by 131% in the presence of lactate dehydrogenase and malate dehydrogenase activation. The detected changes are evidence of tissue energy debt in atherosclerosis, they reflect the character of metabolic acidosis formation and point to the presence of conditions for intensified liposynthesis.
