Source and significance of serum alkaline phosphatases in diseases of the locomotor system.

A group of 292 patients with diseases of the locomotor system was examined. Elevated activity of the liver isoenzyme of serum alkaline phosphatase was found in rheumatoid arthritis. Evaluation of the alkaline phosphatase isoenzyme in these states is especially important for studying nonspecific irritation of the liver tissue as a result of long-term therapy. Significantly elevated bone isoenzyme activity was found in Paget's disease, ankylosing spondylitis and osteoporomalacia, gout, the hyperuricaemic syndrome and some osteoarthroses. In these states, study of the alkaline phosphatase isoenzymes is of particular significance in evaluation of the development of metabolic bone changes. An association between elevated bone and intestinal isoenzyme activity was found. The diagnostic value of the determination of serum alkaline phosphatase is multiplied if the isoenzymes are also evaluated.

Nonspecific collagenolytic activity of the femoral bone in immobilized rat extremities.

Nonspecific collagenolytic activity was studied in rat bones after immobilization. The left hind limb was immobilized by sectioning the sciatic nerve. Enzyme activity was determined by using synthetic pentapeptide substrate (Pz-Pro-Leu-Gly-Pro-D-Arg). After immobilization the activity of nonspecific collagenase increased and reached its maximum on the third day after the operation. The activity was decreased after one week and attained levels of control bones three weeks after sciatic nerve section.
