    Abstract:
    The effect of bone cement used for stabilization of hip joint endoprosthesis on the activity of lysosomal enzymes in peripheral blood granulocytes was studied. The operations were carried out under balanced, non-toxic, endotracheal anaesthesia using muscle relaxants. The blood for tests was obtained from an antecubital vein before and during anaesthesia, before application of bone cement, and 10 min., 1 hour and 24, 48 and 72 hours after endoprosthesis implantation using bone cement. The activity of acid phosphatase, acid protease and neutral protease was determined by calculating it in relation to protein level in the studied fractions. During anaesthesia as well as during the operation when bone cement was applied no statistically significant differences were found in the activity of lysosomal enzymes. On the other hand, after the operation statistically significant changes were found in the activity of lysosomal marker enzymes. Lability of lysosomal membranes appeared with permeation of hydrolases into supernatant. These results confirmed the importance of lysosomal proteins in the processes of wound healing and general postoperative course.
