[Structural-functional changes in lymphocyte ans erythrocyte membranes after exposure to alternating magnetic field].

The lymphocyte membrane fluidity, membrane potential, isoenzyme spectrum of superoxide dismutase (SOD) and catabolic product level of blood cell receptors in rats, healthy volunteers and patients with ovary and skin tumors were studied under the influence of low frequency electromagnetic field (EMF). The increase of fluidity of rat blood lymphocyte membranes was observed at 20 and 40 min exposure of the lymphocyte suspension to EMF. The increase of ANS fluorescence observed after 20 min exposure to EMF suggested a decrease of cell membrane potential.

[Changes in lymphocyte and erythrocyte membrane microviscosity in cancer patients].

Lymphocyte and erythrocyte membrane microviscosites of lipid-protein contact zones and lipid bilayer in blood of patients with gastric, urinary bladder and ovary cancers were investigated in comparison with healthy volunteers by means of coefficients of eximerization of fluorescent probe pyrene. The decrease of membrane fluidity (i.e.
