[Comparative characteristics of lipids, lipoproteins and free radical processes in blood of rabbits after ionizing irradiation and dietary cholesterol administration].

Comparative study of spectrum of lypoids and lipoproteins has been conducted and also of parameters of free radical processes in blood after exposure of organisms of experimental animals to ionizing irradiation in dose of 5 Gy and inclusion of cholesterol into diet. Intake of cholesterol to experimental animals irradiated caused specific impact on indices studied testifying about deep changes in metabolism. It is important during analysis of complex set of postradiation metabolic symptoms observed in clinics.

[The composition and physicochemical properties of the blood lipoproteins in rats exposed to external gamma irradiation].

Content of lipids, character of chemiluminescence of blood plasma and certain classes of lipoproteins have been studied. Geometrical parameters, nature and quantity of charged groups of lipoprotein particles accessible for titration have been determined 1 and 30 days after a single external gamma irradiation of rats in a dose of 3 Gy. The used irradiation dose exerts an expressed hyperlipidemic effect retained for one month after irradiation.

[Comparative characterization of the lipoprotein spectrum and status of free radical processes in the blood of rabbits exposed to external gamma-irradiation and cholesterol administration].

Characteristic of lipoprotein spectrum and state of free-radical processes in the animals under action of ionizing radiation and cholesterin diet are comparatively studied. The content of lipids in the blood serum increases on the 5th day after irradiation and then decreases on the 15th and 30th days. Cholesterin diet increases the content of cholesterin under practically unchanged content of triglycerides in the blood serum in all the terms of investigations.

[Blood lipids and characteristics of free radical processes in specific classes of lipoproteins in rats in the early periods after gamma-radiation].

The content of lipids and lipoproteins, the state of free-radical processes and the level of eicosanoids (prostaglandin F-1L and thromboxane B-2) have been studied in the blood plasma and in certain classes of lipoproteins in rats 2 and 24 h after external gamma-radiation in doses of 1.2 and 3 Gy. Hypertriglyceridemia and hyperprebetalipoproteinemia, whose expressivity increases with a radiation dose are revealed.

[The content of ceruloplasmin, fibronectin and selenium in the blood of patients with an acute myocardial infarct].

The content of ceruloplasmin, fibronectin and selenium was evaluated in the blood plasma of acute myocardial infarction patients within the first three days after onset if the disease. Results showed a reduction of fibronectin during the first hours after onset of the disease. The content of ceruloplasmin was increased, selenium reduced during the entire period of examination indicating pronounced disturbances of lipid peroxidation in the acute period of myocardial infarction as well as potentiation of antioxidant processes.
