Study of the properties of doxorubicin-resistant cells affected by acute leucosis.

The stiffness of cell membrane was found to be one of the factors determining resistance of a cell in vitro to antibiotic doxorubicin action. Membranes of surviving cells are negatively charged (-35 - -30 mV) and have high values of stiffness (2.2-5.

C60 fullerene affects elastic properties and osmoregulation reactions of human lymphocytes.

The influence of aqueous solution of pristine C60 fullerene (C60FAS) on functional activity of lymphocytes from a healthy person was studied for the first time. By means of atomic force microscopy, it was found that C60FAS in a concentration of 0.1 mg/ml increases the stiffness of the lymphocyte membrane by 41% (p < 0.
