[The histoenzymological diagnosis of the time of occurrence of a closed spinal cord trauma].

Time course of the activities of transport enzymes in capillary walls of human spinal cord was studied in various periods after closed injury to the cord, inflicted by hard blunt objects, with the use of histochemical methods for the detection of alkaline phosphatase and Mg-dependent ATPase. Wave-like fluctuations in the activities of the examined enzymes were revealed. The findings may be used to assess the period elapsed since the cord injury.
