title: [Investigation on the fluorescence spectroscopy of normal and malignant rectum tissues].
abstract: In the present article the fluorescence characteristics of normal and malignant rectum organ tissues of 12 samples were investigated in vitro using UV (200-400 nm) fluorescence spectroscopy and compared with the results of the infrared spectra of normal and malignant rectum organ tissues. The results showed that the fluorescence intensity of normal rectal tissue was higher than that of rectal malignant tissue. The difference in fluorescence intensity at 492 and 544 nm between normal rectal tissue and malignant tissue may be considered as a detection criterion.
