SHF radiation from albumin solution upon external excitation.

The purpose of the research consisted in the measurement of nonequilibrium radiation in superhigh frequency (SHF) range from aqueous solution of albumin upon its mechanical stimulation.

Methods: the monitoring of change in the ratio between brightness temperatures TSHF and TIR values after the mechanical stimulation of aqueous solution of albumin in the measuring cell at 35-39°С. The measurements of brightness temperatures were carried out with use of radiothermometer. SHF frequency range corresponded to 3.4-4.2 GHz, SHF frequency range corresponded to 8-13 mm.

Results: It was found that mechanical stimulation of aqueous solution of albumin at the temperature ~39°С, the change in the ratio between TSHF and TIR occurs. This corresponds to emergence of nonequilibrium SHF radiation from the solution near the phase transition with ~39°С temperature.

Conclusion: The effect of emergence of nonequilibrium SHF radiation from protein solution near its temperature 39°С was found. This temperature corresponds to the temperature of human organism upon a number of pathological states connected with inflammatory processes. The discovered effect can be used in the development of novel non-invasive methods of disease diagnostics.
