[Redox and proteolytic enzymes in brain tissue after a concussion].

The article deals with the results of histochemical study of some redox and proteolytic enzymes (SDH, MDH, NAD-diaphorase, LDH, and acid and alkaline phosphatase) in experiments on animals in various periods after infliction of a craniocerebral injury and on autopsy material, i.e. the brain of patients who had died from severe craniocerebral injury incompatible with life. It is shown that the activity of all enzymes decreases (SDH, MDH, NAD-diaphorase, and alkaline phosphatase) or increases (LDH, acid phosphatase) in various periods after the injury. The results were compared with the findings of morphological examination of the same brain areas performed by means of neurohistological methods.
