[Recording of the chemiluminescence of the component parts of the blood serum in the presence of divalent iron].

Measurements of chemiluminescence of apo-B-containing lipoproteins of blood serum enables one to evaluate their capability of peroxidation in the presence of ferrous ions. The recording of chemiluminescence changes in the standard chemiluminescent system in the presence of ferrous ions after adding the supernatant remained after the precipitation of apo-B-containing lipoproteins may serve a simple test for the assessment of blood serum antioxidant activity.

[Chemoluminescence of blood serum lipoproteins isolated by means of ultracentrifugation and precipitation with heparin and calcium].

Apo-B containing lipoproteins obtained after precipitation with heparin and calcium as well as very low (LPVLD) and low density lipoproteins (LPLD) produced using preparative scale ultracentrifugation had identical chemoluminescent properties. However, LPVLD are involved only slightly in total chemoluminescence of apo-B containing lipoproteins due to their low concentration in blood serum. In blood serum there is the factor having the quenching effect on the chemoluminescence and also exhibiting the antioxidant activity.

[Complex immunochemical examination of patients with some liver disorders].

Complex differential-diagnostic immunodiffusional test for a number of blood plasma proteins, antigens of liver tissue and alpha-fetoprotein was used to evaluate the liver tissue functional state. The test characterized more distinctly the liver tissue function as compared with estimation of individual proteins and was more informative in diagnosis of liver tissue disorders.
