- Аннотация: Background: Development of alternative methods of non-invasive therapy in neurooncology is determined by the need to prevent the continued growth of glioblastoma and radiation-induced complications. Usage of electromagnetic influence for these reasons is determined by the oscillatory nature of intracellular processes and results of previous studies on the effect of weak electromagnetic radiation in tumor growth. The purpose of the study was to reveal the effect of a pulsed magnetic field (PMF) and ionizing radiation (IR) on human T98G glioblastoma cells. Methods: Human T98G glioblastoma cells were cultured in the RPMI-1640 medium (Biolot, Russia) supplemented with 10% fetal bovine serum (Thermo Scientific HyClone, USA). The culture was seeded in the Biofil plates (at least 8x105 cells per 3 mL of the medium), incubated (CB 150 Binder, Germany) and exposed to IR 10 Gy (TheratronEquinox-BestTheratronics) for 11.7 min. and/or PMF 15 mT or 300 mT with a sequence of frequencies 0.3-3.0-9.0 Hz for 7 min. (Neiro-MS/D by Neirosoft, Russia). The efficiency criteria were lethality and the mitotic activity of human T98G glioblastoma cells. Results: The highest cellular lethality was registered 3 hours (18.7 vs. 5.2% in controls, p≤0.05) and a day after IR exposure. PMF 15 or 300 mT alone increased lethality by 2.5-2.8 times compared to controls (p < 0.05). IR plus PMF (15 mT) did not caused increased lethality. At the same time, the most pronounced decrease in the mitotic activity a day after exposure (by 4.7 times, p < 0.05) was registered in PMF alone (15 mT). Conclusions:The inhibitory effect of PMF on the viability of human glioblastoma cells indicates the prospects for its use as an accompanying treatment in neurooncology.
