Аннотация: The effects of cisplatin on [Ca(2+)](in), pH(in), NAD(P) H level, and lymphocyte membrane microviscosity were studied in mice with Ehrlich ascitic carcinoma. The level of free [Ca(2+)](in) in lymphocytes from mice with Ehrlich ascitic carcinoma was 4-fold reduced compared to that in intact animals on day 13 of tumor development, while [H(+)](in) level was elevated. Cisplatin caused no changes in the level of free Ca(2+), but reduced cytosol acidification. Lymphocyte membrane fluidity in mice with tumors was increased in the lipid bilayer and in the protein-lipid contact zone and did not depend on cisplatin treatment. The level of NAD(P) H was low in mice with tumors, but increased sharply after cisplatin treatment. It seems that functional activity of lymphocytes decreased at the stage of well-developed tumor, which promoted inhibition of the lymphocyte defense properties. Cisplatin did not modify the structure and functions of lymphocytes and presumably even improved their energy status.
