Activity of 8 glycosidases (6 acid lysosomal and 2 neutral cytosolic enzymes) was estimated in lymphoid cells of 28 patients with different forms of lymphoproliferative disorders: B- and T-chronic lymphocytic leukemia (CLL), non-Hodgkins lymphoma (NHL), Sezary syndrome, hairy cell leukemia (HCL) and B- and T-acute lymphoblastic leukemia (ALL). Activity of these glycosidases was also studied in mononuclear cells and granulocytes of healthy volunteers and in immature myeloid cells of 16 patients with chronic myeloid leukemia (CML). In lymphoid cells of all the patients studied (except of ALL) the glycosidases activity was decreased as compared with that of normal mononuclear cells and immature myeloid cells. Activity of the majority enzymes studied was higher in T-lymphoid cells of patients with lymphoproliferative disorders as compared with B-cells. The highest glycosidases activity was found in ALL cells and the lowest--in CLL cells of the patients with B-lymphoid cells forms of the disease. Activities of N-acetyl-beta-D-hexosaminidase, alpha-D-mannosidase and beta-D-glucuronidase were distinctly dissimilar in cells of the patients with B-CLL, B-NHL and HCL. Estimation of these glycosidases activity in lymphoid cells may be of importance in differential diagnosis of lymphoproliferative disorders.

To limit the genetic heterogeneity of schizophrenia, this study focused on the widely extended pedigrees of Ashkenazi Jewish schizophrenia probands. The hypothesis posed is that the increased prevalence among the Ashkenazim of the rare lysosomal enzyme disorders, Tay Sachs disease (TDS), caused by low levels of hexosaminidase A, and Gaucher's disease (GD), caused by low levels of glucocerebrosidase, might contribute to the demonstrated increased vulnerability to schizophrenia in this ethnic group. Signs and symptoms characterizing the candidate illnesses were systematically queried by the family history method. Rates and relative risks for symptoms characterizing these disorders and for several nonautosomal illnesses associated with TSD and/or GD (i.e., amyotrophic lateral sclerosis and Hodgkin's disease, leukemia and lymphoma) are significantly elevated in the schizophrenia pedigrees, compared to controls. The conditions with elevated rates and risks have been associated with chromosomal regions 1q21 and 15q23-q24. These areas are suggested as candidate regions for future targeted deoxyribonucleic acid (DNA) research in schizophrenia.
