ABSTRACT
Some enzymatic activities have been essayed in the gastrocnemius muscle of patients with obstructive arteriopathy of the lower limbs. The specific activities of all the examined glycolytic enzymes, of malate dehydrogenase and of glycerol-3-phosphate dehydrogenase are significantly decreased while the specific activities of two lysosomal enzymes, β-glucuronidase and cathepsin A, are significantly higher than in the controls. Therefore it may be inferred that the metabolic capacity of glycolysis and of Krebs cycle are lowered. On the other hand the increased specific activity of lysosomal enzymes suggests the hypothesis that the above mentioned modifications and the morphologic alterations of the muscle and of the small blood vessels might be ascribed, at least partly, to a release of lysosomal hydrolases in active form.
