  The aim of the study was to synthesize (La, Sr)MnO3 no particles as heating mediator and evaluate the ability of nano hyperthermia to affect ascitic forms of cancer as well tumor cells resistant to cytostatic. Nanoparticles have been synthesized by sol-gel method and magnetic fluid on the basis of nanoparticles was prepared. It is heated under alternating magnetic field (300kHz,7.7kA/m) and able to heat tumor cells. Nano hyperthermia is able to enhance the sensitivity of cisplatin resistant tumour cells (MCF-7Cp) to cytostatic action: about 30% of resistant tumor cells could overcome the resistance to cisplatin. Anti-tumor effect of nano hyperthermia was confirmed by the absence of ascitic fluid in peritoneal cavity of mice with lymphocytic leukaemia Р-388 (аscitic form). It may be explained by the ability of nanoparticles to penetrate into the tumor cells and to cause the phenomenon so named as “intracellular hyperthermia” as it was demonstrated by electron microscopy. Applying of nano hyperthermia using (La,Sr)MnO3 nanoparticles may be considered as the promising way to help in approaches to the problem of tumor cell resistance as alternative to the conventional chemotherapies. Nano hyperthermia intraperitoneal chemotherapy may be helpful within various multimodality strategies for prevention and treatment peritoneal carcinomatosis or malignant ascites.
