Fourier transform infrared spectroscopy technology was applied to measure the normal,hyperplastic,malignant mammary tissue of albino rat which DMBA was injected into.The analytic results indicate:there are distinct difference between FTIR of the normal mammary tissue and its malignant mammary tissue.Some characteristic spectrums are shifted(for example:1745cm-1,1378cm-1,1465cm-1,970cm-1),and the intensity of them have changed.Discussing the difference can provide doctor with some gist of researching the rea...
