Effect of chronic gamma-irradiation and beta-carotene on lipid metabolism in presynaptic membranes in rat brain

Lysophosphatidylcholine is involved in radiation-induced modulation of presynaptic membranes in rat brain. High sensitivity of the cortical integrative functions to chronic low-dose gamma-irradiation is demonstrated. beta-Carotene produced a protective effect during chronic irradiation.
