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.
完整红细胞影的红外光谱未观察到蛋白质分子的β结构。1009兆赫兹、强度为45毫瓦/立方厘米范围内的超高频辐射会导致膜中分子的小构象重构，但不会诱导α螺旋或卷曲显著转变为β结构。光谱显示1740厘米-1处脂质带强度降低。氘交换36 - 38分钟表明，在超高频辐射下，1540厘米-1附近的酰胺II带向1450厘米-1带的转变比对照更快。观察到的效应与超高频场的强度直接相关，在5 - 8毫瓦/立方厘米及更低强度时消失。
