to study the extent , duration , and localization of metabolic changes in vein-to-vein grafts in rats , the sequential changes in enzymatic activity of veno-venous grafts in rats were evaluated by histochemical demonstration of the activity of two oxidoreductases ( lactate dehydrogenase and succinate dehydrogenase ) and two hydrolytic enzymes ( adenosine triphosphatase and alkaline phosphatase ) .
