School of Life Science Technology, Univ. of Elec. Sci. Tech. of China Chengdu 610054; 2. Department of Pathology, West China Hospital, Sichuan university Chengdu 610041) Abstract 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 l
