ecg , histological , and histochemical examinations on a model of experimental myocardial infarction showed that hyaluronidase administration leads to a decrease in the sum of elevation of the st segment and the number of points ( nst ) at which this elevation is recorded , acceleration of healing processes in the affected zone , and to activation of respiratory enzymes and the pentosophosphate shunt in some of the fibres of the peri-infarction zone .
