Effects of singlet oxygen therapy may be сonplimented by nitric monooxide: mass spectrometric findings

The purpose of this study was to clarify the composition of the gas flow from the singlet oxygen generator and its features relative to air as a carrier gas. The mass spectra of the exhaust gases were recorded by a quadrupole mass spectrometer Extorr XT 300(M) Series VGA with a resolution of 1 atomic unit of mass (aem). The spectrum of the gas flow was analyzed in the standard operating mode of the "Airnergy" generator, as well as when shielding the aqueous medium from radiation with an impermeable membrane for it. The spectra were evaluated by the presence of characteristic bands of particle mass. It is revealed that the treatment of the air flow in the "Airnergy" apparatus, including its humidification and exposure to UV radiation, significantly transforms its qualitative and quantitative composition. In the outgoing stream, a decrease in the level of carbon dioxide and molecular oxygen is detected with a simultaneous increase in the concentration of nitric monoxide (NO). This circumstance has a special biological significance, since the presence of this compound in the gas stream from the singlet oxygen generator can complement and transform the effects of this reactive oxygen species in relation to biological systems.
