The erythrocytes of human blood were sequentially irradiated with a low-intensity laser (λ = 640 nm), a violet LED (λ = 400 nm), a green LED (λ = 540 nm), and a yellow LED (λ = 592 nm). The method of acid (chemical) erythrograms and the method of counter ion transport compared the kinetic characteristics in irradiated and unirradiated blood samples. Received: - by the method of acid erythrograms it was found that in the irradiated blood samples there is a decrease in the time of hemolysis; - low intensity laser radiation, as well as the emission of LEDs, increase the rate of counter ion transport through red blood cells. - a decrease in the time of hemolysis and an increase in the rate of counter ion transport of irradiated blood samples is due to a decrease in the "effective" thickness of the near-membrane diffusion layer - an immiscible layer of water adjoined to the erythrocyte membrane. A decrease in the "effective” thickness of the near-membrane water layer (minimal in the wavelength range of 570-590 nm and 630-640 nm) changes the rate of metabolic processes in the "cell - intercellular medium" system, changing the mode of cell functioning. The altered mode of functioning is a biological response to light radiation. Red blood cells with an altered mode of functioning are signals - stimuli that cause the body to mobilize resources to fight pathology. These circumstances can predict the creation of a universal phototherapeutic equipment for extracorporeal blood irradiation based on light-emitting diodes with certain exposure parameters.
