EFFECT OF LOW-FREQUENCY MAGNETIC FIELD ON STRUCTURE OF THE BLOOD GLOBULAR PROTEINS
IR absorption spectra of blood were used to study the structure change of globular proteins at extracorporal autohemomagnet therapy applying for heart ischemia treatment. The spectra of blood before and after magnet-therapy were compared in the several regions: Amid I (1655 cm-1), Amid II (1545 cm-1), Amid III (1230-1350 cm-1), Amid IV and V (400-700 cm-1). It is shown that spectrum changes induced by direct magnetic field action on the blood in vivo are associated with the conformational changes in the secondary structure of blood globular protein, which manifest itself in a pronounced increase of the α-helical conformation content. The emergence of new absorption bands in the region 900-1200 cm-1 was observed for several samples after magnet-therapy due to the possible concentration changes of some blood components.
