[Glutathione-dependent enzymes and glucose-6-phosphate dehydrogenase of blood in patients with lymphosarcoma (non-Hodgkin's disease)].

Activities of glutathione-dependent enzymes and glucose-6-phosphate dehydrogenase (GPDH) were studied in blood of the patients with lymphosarcoma (LS). The activity of glutathione reductase (GR), glutathione dehydroascorbate reductase (GDAR), gamma-glutamyltranspeptidase (GGT) and G6PDH in plasma, leucocytes, lymphocytes and erythrocytes of peripheral blood in 30 patients (42-56 years) with LS and in 20 healthy have been determined with spectrophotometric methods (Humalyzer 2000 DE). Leucocytes and lymphocytes were separated from blood using Boyum method.

[MALT-lymphomas with primary gastric focus].

The peculiar features of the clinical course and treatment of primary gastric MALT-lymphoma in 7 patients are discussed. Diagnosis was established by morphological examination of resected material. Six patients had low-grade tumor while one showed signs of blast-transformation.
