通过光镜下的组织病理学观察，采用高分辨率的傅里叶变换红外光谱仪，对长期暴露在高场强低频电磁场环境中的大鼠肺组织和对照组大鼠肺组织进行了对比研究，力求从分子水平上揭示暴露组大鼠肺组织和对照组大鼠肺组织的红外吸收光谱存在差别的原因，为进一步探讨高场强低频电磁场造成生物体组织损伤的作用机制提供实验依据。Tissue’s pathological changes are observed and analyzed and paraffin sections are studied by fourier transform infrared spectroscopy technology on lung tissues to observe the effluence on tissues of rats which are exposed to high intensity low-frequency electromagnetic fields. Results show that there are some differences between exposed group and control group on both lung tissue sections and spectra, These differences is are mainly caused by changes in composition and structure of micro-molecules and changes of vibrational modes of the function groups in biological tissues. Results indicate that high density low-frequency electromagnetic radiation may be caninogenic for lung tissues of rats with long time exposure.
