A mechanism of the cytotoxicity of plasma-activated medium (PAM) is revealed by examining the intracellular effects of reactive oxygen nitrogen species (RONS) and lipid oxidation. PAM is cell culture medium activated by irradiation using non-equilibrium atmospheric-pressure plasma using pure Ar gas in ambient air. Extracellular RONS in PAM induced the apoptotic death of HeLa cells. Temporal changes in intracellular RONS, such as ONOO − , NO, and O À 2 , were analyzed. Intracellular RONS generation in HeLa cells following incubation in PAM triggered activation of the caspase cascade pathway and lipid peroxidation of intracellular membranes to induce apoptosis.

Plasma medical science is a novel interdisciplinary field that combines studies on plasma science and medical science, with the anticipation that understanding the scientific principles governing plasma medical science will lead to innovations in the field. Non-thermal atmospheric pressure plasma has been used for medical treatments, such as for cancer, blood coagulation, and wound healing. The interactions that occur between plasma and cells/tissues have been analyzed extensively. Direct and indirect treatment of cells with plasma has broadened the applications of non-thermal atmospheric pressure plasma in medicine. Examples of indirect treatment include plasma-assisted immune-therapy and plasma-activated medium. Controlling intracellular redox balance may be key in plasma cancer treatment. Animal studies are required to test the effectiveness and safety of these treatments for future clinical applications.Keywords Plasma medical science Á Plasma cancer therapy Á Plasma-activated medium (PAM) Á Reactive oxygen species (ROS) Abbreviations ALKAnaplastic lymphoma kinase AMD Age-related macular degeneration APF Aminophenyl Fluorescein CNV
