[The effect of irradiation on the lipid composition of plasma membranes of liver cells].

The level of total phospholipids decreases, a cholesterol/phospholipid molar coefficient increases, and lipid/protein ratio in plasma membranes of liver cells decreases at early times following total-body X-irradiation of rats (LD50/30). Changes in individual phospholipids were differently directed. A possible correlation between the data obtained and the structural-functional status of the surface membrane is discussed.
