Cold Argon Athmospheric Plasma for Biomedicine: Biological Effects, Applications and Possibilities.

Currently, plasma medicine is a synthetic direction that unites the efforts of specialists of various profiles. For the successful formation of plasma medicine, it is necessary to solve a large complex of problems, including creating equipment for generating cold plasma, revealing the biological effects of this effect, as well as identifying and justifying the most promising areas of its application. It is known that these biological effects include antibacterial and antiviral activity, the ability to stimulate hemocoagulation, pro-regenerative properties, etc.

Experimental Evaluation of the Effect of Argon Cold Plasma on Oxidative Metabolism of the Blood.

We studied the effect of course exposure to argon cold plasma (ten 1- and 2-min procedures) on some parameters of the oxidative metabolism of rat blood plasma. The intensity of free radical processes, the total antioxidant activity, and malondialdehyde concentration in rat plasma were evaluated. It was found that 2-min exposure to argon cold plasma and nonionized argon stream produce a prooxidant effect, while 1-min exposure argon plasma led to stimulation of the antioxidant reserves of the blood.
