通過光鏡下的組織病理學(xué)觀察，采用高分辨率的傅里葉變換紅外光譜儀，對(duì)長期暴露在高場(chǎng)強(qiáng)低頻電磁場(chǎng)環(huán)境中的大鼠肺組織和對(duì)照組大鼠肺組織進(jìn)行了對(duì)比研究，力求從分子水平上揭示暴露組大鼠肺組織和對(duì)照組大鼠肺組織的紅外吸收光譜存在差別的原因，為進(jìn)一步探討高場(chǎng)強(qiáng)低頻電磁場(chǎng)造成生物體組織損傷的作用機(jī)制提供實(shí)驗(yàn)依據(jù)。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.
