[Action of the red and infrared electromagnetic waves of light-emitting diodes on the behavioral manifestation of somatic pain].
Research of analgesic action of electromagnetic waves (EMWs) of red (1 = 640 +/- 30 nm) and infra-red (1 = 880 +/- 30 nm) light-emitting diodes of device "MEDOLIGHT" on a tonic and acute pain of white outbreed male mice is carried out. The tonic pain was caused by hypodermic injection of 20 ml of 5% formalin solution in a back surface pad of a hinder leg. Acupuncture point (AP) E-36 or the center of pain were exposed to the action of red or infrared light-emitting diodes in cumulative density of steam radiation capacity during 10 min by 26 mWt/ cm2 in continuous or pulse regimen for frequencies 10, 600, 8000 Hz. ⋯ In experiments with a tonic pain the summary pulse action on AP E-36 of the red and infrared EMWs with frequencies 10, 600, 8000 Hz reduced twice quantity of paw twitchings of animals with pain. The greatest efficiency in suppression of tonic pain syndrome observed for frequencies of 10 and 8000 Hz. The data received testify that the hypoanalgesic effect of light-emitting diode EMWs depends on area of influence, lengths of wave and the modes of an irradiation chosen in view of intensity and duration of stimulation.

Comparative Study[The characteristics of the effect of inert gases on tissue respiration in vivo].
Helium-oxygen and argon-oxygen gaseous mixtures have been studied for their effect on tissue respiration. It is shown that 1-hour exposition of animals induces an increase in the oxygen consumption of the liver tissue (more essential in the presence of helium in the gaseous mixture).
