[The effect of superoxide dismutase on the blood lipoprotein level of rabbits in the dynamics of traumatic shock].

Changes of the lipoprotein (LP) level in blood in the abdominal aorta and the portal and hepatic veins were studied in experiments on rabbits with Cannon's traumatic shock. The LP level was determined by spectrophotometry. The blood LP level changed depending on the stage of the shock. Administration of superoxide dismutase (an enzyme whose biosubstrates are only products of a free-radical process) in the initial period of shock has a normalizing effect on the level of the main LP classes.
