红外光曝露对于大鼠组织影响的傅里叶变换红外光谱研究

FTIR Spectra Investigation of Rat Tissues Exposure to Infrared Light

生物组织受到外界电磁场曝露以后,生物分子的结构可能会发生变化,所发生的变化可以从组织的红外光谱的变化得到确认。为了研究红外光曝露对血液、睾丸以及脑组织的影响,对曝露于红外光条件下30天的大鼠的血液、睾丸和脑组织进行了红外光谱测量,将测试结果在1 700～1 000cm-1范围内与对照组进行了对比,并利用红外光谱的二阶导数谱进一步分析红外光曝露对生物各组织微观结构特性的影响,探讨了红外光曝露的作用位点及其机制。研究结果表明红外光曝露可致大鼠组织的红外光谱特征发生一定的变化,傅里叶变换红外光谱技术可以用于分析红外光曝露对于生物组织微观结构的影响及其发生机制。

Structure of biological molecules may change when exposure to electromagnetic field, the change can be recognized from the change of the infrared spectrum.The present paper studied microstructure of rat blood, testis and brain after its expo- sure to infrared light for 30 days via their FTIR characteristics within the 1 700-1 000 cm-1 range, and the authors also ana- lysed biological characteristics of tissue microstructure with infrared light exposure on rat by their second derivative spectra. Mechanisms of biological effects induced by infrared light were further explored through the findings. All the results indicate that the Fourier transform infrared spectroscopy can be used to analyze infrared light exposure for biological tissue microstruc- ture.
