[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 activation of free-radical processes, an increase of the thromboxane V-2 content and a decrease of the prostaglandin F-1L content are observed with a dose of 1 Gy.
