| Abstract: | The activity of acid phosphatase, beta-glucuronidase and N-acetyl-beta-glucosaminidase was assessed using semiquantitative cytochemical methods in peripheral blood lymphocytes of 45 untreated patients with gastric cancer and 80 healthy subjects. In cancer patients the study demonstrated a statistically significant decrease in the number of lymphocytes with granular reaction for acid phosphatase and N-acetyl-beta-glucosaminidase, as well as an increase in the number of lymphocytes showing a granular-diffuse reaction for the above enzymes and a diffuse reaction for all the studied lysosomal enzymes. Possible mechanisms of the observed changes are discussed. |
