[Determining the level of occurrence of the lipid nucleus of atherosclerotic plaques in the abdominal aorta by means of infrared Fourier spectroscopy].

The article deals with the problem of diagnosis of atherosclerotic alterations in abdominal aorta wall in order to reduce atherosclerosis-related mortality. Targeted treatment requires determining the exact mechanism of development of atherosclerosis. Infrared Fourier spectroscopy is suggested as the most rapid and accurate method of diagnosis and analysis of the content of various organic compounds playing a particular role in the development of the atherosclerotic process.

[Peptide-bound oxyproline content in patients with nail hyperkeratosis and lactic acidosis].

The studies indicate that women with dystrophic changes of the nail in the presence of various skin diseases show a significant blood accumulation of acid products (peptide-bound oxyproline (PO) and lactic acid (LA). A relationship was found between the magnitude of a dystrophic process (hyperkeratosis) and higher blood LA levels with lower PO values that fail to achieve the level observed in the control group.

[The activities of red blood cell superoxide dismutase and catalase and serum alkaline phosphatase in onychodystrophy in women in the stage of nail rejection].

The resistance to a dystrophic process and lysis and the degree of clinical signs in nail lesions in different stages of onychodystrophy were found to be associated with the activity of alkaline phosphatase. A relationship was established between the magnitude of the blood activity of the enzymes superoxide dismutase and catalase with a drop in the serum activity of alkaline phosphatase. At the same time, there was a correlation between the rate of development of onychodystrophy and the magnitude of a change in the activity of antioxidant defense enzymes.
