[The use of enzymes in treating patients with malignant lymphoma with a large tumor mass].

Systemic enzymes (wobenzime and wobe-mugos) were approved, that had been prescribed as part of polychemotherapy to 24 patients with malignant lymphomas, who presented with large masses of lymphatic nodes poorly resorbable against the background of polychemotherapy and who were assigned for a high-total dose irradiation, which fact would undoubtedly entail sclerosing of adjacent intact tissues. The use of the enzymes made for the optimum realization of the polychemotherapy effect and permitted avoiding a good many of undesirable side events and complication thereof. The above systemic enzymes are well tolerated by patients; they induce no significant changes in the cellular composition or in blood biochemical indices.

[The use of propes in the combined treatment of malignant lymphomas].

Results are submitted of use of propes during different phases of treatment in 36 patients with malignant lymphomas. The above drug is associated with no complications or side effects, inhibits the development of the tumor process. The employment of propes permits enhancing both natural resistance of the organism and its killer activity.

[Modulation of lipid peroxidation by biogenic amines in model systems].

Specific effects of serotonin, histamine, noradrenaline and tyramine on the rate of lipid peroxidation were studied in model systems by means of measurement of malonic dialdehyde and Schiff base concentration as well as of kinetics of O2 consumption. Alterations in the lipid peroxidation rate in the presence of biogenic amines occurred dissimilarly depending on localization of oxidation substrates either in bilayer membranes or in micellar solution. The antioxidative effect of serotonin was the most pronounced as a result of its ability to react with lipid peroxidation radicals.

[Structural changes in the DNA of the blood nucleotides and the development of late sequelae in irradiated rats].

Fluorescent analysis of structural changes of nucleotide in the blood associated with AT fragments has been studied in rats, gamma-irradiated with doses of 2 and 4 Gy. It was demonstrated that the haematological, gerontological and cancerogenic late consequences were preceded by the structural genomic disturbances determined by 30 day after irradiation.

[Familial cases of lymphogranulomatosis].

Among patients with Hodgkin's disease 30 cases of the family disease were revealed during 1972-1988. The occurrence of family pairs of patients with Hodgkin's disease suggests a heritable anomaly or inheritance of a gene predisposing for this disease. In cases of contacts with second degree relatives and children from a single family, one cannot exclude a role of environmental factors and a concurrent transfer of the infectious factor.
