[Effect of carbostimulin and vitamin D3 on activity of glycolytic enzymes of rabbit bones, regenerates and muscles].
Activity of glycolysis enzymes such as: phosphofructokinase, aldolase, phosphoglucomutase, was determined in the regenerate of a bone, bone fragments, native bone and, for the sake of comparison, in the animal muscles after the radius resection and feeding of carbostimulin and its mixture with vitamin D3 for 10 days. On the 12th day after the radius resection the phosphofructokinase activity in rabbits increases in the native and operated bones as compared to that in bones of nonoperative animals. In the group of rabbits which were fed on the mixture of carbostimulin and vitamin D3 the phosphofructokinase activity is 7-2 times as high. In the regenerate of these animals the activity becomes 12 times as high as that in the regenerate of the control rabbits. An analogous increase in the aldolase and phosphoglucomutase reaction rate is observed in the bones of the animals which received carbostimulin and vitamin D3 (4.5 and 7.5 times, respectively). The same tendency to the increase in the activity of these enzymes is observed in the regenerate tissue. In the muscular tissue at this stage of regeneration the activity of the studied enzymes which is usually high in norm decreases.
