[Synaptosome membrane proteins of the rat brain in convulsions caused by increased oxygen pressure]

High oxygen pressure (0.7 MPa during 30-40 min) increased the quantity of high molecular proteins with simultaneous decrease in amount of low molecular proteins in rat brain synaptosomes. At the same time, the significant increase of lipoprotein fluorescence with emission at 435 nm was observed. Oxygen at high pressure inhibited incorporation of 14C-leucine into synaptosomal membrane proteins. Possible mechanisms of these alterations are discussed.
