[The superoxide dismutase activity of the brain and liver tissues in a rabbit with an experimental brain concussion].

Abstract

A study is presented of the activity of superoxidedismutase and catalase in the brain and liver in the dynamics of mild head injury in experiments on rabbits. It was established that the activity of catalase in the brain show a three-times reduction within 15 minutes after the injury. The catalase activity in the liver remains practically unchanged. The activity of superoxidedismutase in the liver in the posttraumatic period does not differ from control values. In the brain superoxidedismutase activity reduces by 38% only on the 7 and 14 days after injury.
