[Infrared spectra of erythrocyte shadows in the region of the amide I and amide II bands following microwave irradiation].
No beta-structures of protein molecules were observed by IR-spectra of intact erythrocyte shadows. Ultra high frequency irradiation in the range of 1009 mHz intensity of 45 mW/cm3 results in small conformational reconstructions of molecules in the membrane, but it does not induce a notable transition of alpha-helix or coil into beta-structure. A decrease of the intensity of lipid band by 1740 cm-1 is shown up at the spectra. Deuterium exchange for 36--38 min shows that the transition of the band amide II near 1540 cm-1 into the band 1450 cm-1 proceeds faster under UHF irradiation than in the control. The effects observed are in a direct relation-ship with the intensity of UHF-field and disappear at the intensities of 5--8 mW/cm3 and lower.
