title: Lysosomal exoglycosidases in serum and urine of patients with colon adenocarcinoma.
abstract: OBJECTIVE
  The aim of this study is to evaluate the usefulness of determination the activity of lysosomal exoglycosidases: N-acetyl-beta-D-hexosaminidase (HEX - E.C. 3.2.1.30), beta-D-galactosidase (GAL - E.C. 3.2.1.23), alpha-L-fucosidase (FUC - E.C. 3.2.1.51) and alpha-D-mannosidase (MAN - E.C. 3.2.1.24) in blood serum and urine in diagnostics of colon adenocarcinoma.
  
  
  METHODS
  The activity of lysosomal exoglycosidases was determined by the method of Marciniak et al. adapted to serum and urine of patients with adenocarcinoma of the colon.
  
  
  RESULTS
  A significant increase in concentration of the activity of HEX, GAL and FUC was found in blood serum, as well as HEX and GAL in urine, of patients with colon adenocarcinoma, in comparison with healthy people. With the method of Marciniak et al. for determination the activity of HEX, GAL and FUC in blood serum as well as HEX and GAL in urine, the cases of colon adenocarcinoma were significantly differentiated from healthy people.
  
  
  CONCLUSIONS
  The high diagnostic value, sensitivity and specificity of the method of Marciniak et al., suggests the possibility of its use for determination of the activity of HEX, FUC and GAL in blood serum as well as HEX and GAL in urine, in the diagnostics of colon adenocarcinoma.
