Chemiluminescent Analysis of Oxidative Metabolism in Rat Blood under the Influence of Argon and Helium.

We studied the nature of the action of course treatment with argon and helium (1 min, 3 procedures) on the oxidative metabolism in rat blood plasma. The study was performed on 30 Wistar rats divided into 3 groups (n=10 in each group): intact and 2 experimental (treatment of the skin of the back with a stream of argon and helium, respectively). After completion of the treatment course, the intensity of free radical processes, the total antioxidant activity, and malondialdehyde concentration were evaluated in the blood plasma.

Molecular Hydrogen: From Molecular Effects to Stem Cells Management and Tissue Regeneration.

It is known that molecular hydrogen is a relatively stable, ubiquitous gas that is a minor component of the atmosphere. At the same time, in recent decades molecular hydrogen has been shown to have diverse biological effects. By the end of 2022, more than 2000 articles have been published in the field of hydrogen medicine, many of which are original studies.

Near-Field Microwave Tomography of Biological Tissues: Future Perspectives.

This overview shows the mapping of specific visualization techniques, depth assessment of the structure of the underlying tissues and used wavelengths of radiation. Medical imaging is currently one of the most dynamically developing areas of medical science. The main aim of the review is a systematization of information on the current status of the microwave imaging of biological objects, primarily of body tissues.

Spectroscopy of Laser-Induced Dielectric Breakdown Plasma in Mixtures of Air with Inert Gases Ar, He, Kr, and Xe.

The generation of ozone and nitrogen oxides by laser-induced dielectric breakdown (LIDB) in mixtures of air with noble gases Ar, He, Kr, and Xe is investigated using OES and IR spectroscopy, mass spectrometry, and absorption spectrophotometry. It is shown that the formation of NO and NO noticeably depends on the type of inert gas; the more complex electronic configuration and the lower ionization potential of the inert gas led to increased production of NO and NO. The formation of ozone occurs mainly due to the photolytic reaction outside the gas discharge zone.

Some Beneficial Effects of Inert Gases on Blood Oxidative Metabolism: Study.

The aim of the study was to assess the effect of external use of inert gases (helium and argon) on the state of free radical processes in vivo. The experiment was performed on 30 male Wistar stock rats (age-3 months, weight-200-220 g.), randomly distributed into 3 equal groups.
