[The in-vitro effect of constant and pulsating magnetic field on immunocompetent blood cells of hematologic patients].

Immunologic characteristics were studied in 103 patients with multiple myeloma, acute leukemia, chronic lymphocytic leukemia and non-Hodgkin's disease following in vitro exposure of blood to a low-intensity static field (SF) and alternating field (AF) or pulsating magnetic field (PF). In a SF-AF study of multiple myeloma, a 30 min exposure had a positive effect on expression of tumor cells and T-cell markers and stimulated the regulatory function of T-lymphocytes. With SF-AF and PF application alternating, the expression of both +CD3 and +CD4 and the +CD3/+CD4 ratio increased suggesting the lowering of immunological deficiency.

[The effect in vitro of permanent and variable magnetic fields on immunocompetent blood cells from patients with hemoblastoses and non-Hodgkin's malignant lymphoma].

Immunologic parameters were studied in 54 patients with myeloma multiplex (MM), acute leukosis (AL), non-Hodgkin's disease (NHD) before and after in vitro exposure of these patients' blood to weak constant magnetic field (CMF) and CMF in combination with variable magnetic field (VMF). Blood irradiation with CMF over 60 min in AL and MM patients brought about in some cases enhancement of the expression of +CD3, +CD4 and CD8 together with augmentation of the immunoregulatory index. At the same time phagocytic activity of leucocytes got increased as did digesting capability and index of completeness of phagocytosis, i.
