Paper Abstract

Fluorescence spectra of dermal lesions on 48 rats have been investigated using excitation wavelengths of 275 nm, 300 nm and 340 nm. Emission at 340 nm and 460 nm were measured in both forequarter and hindquarter lesions. Unlike 460 nm emission, intensity at 340 nm increased with time and then saturated. Control studies on intact skin and lesions in dead rats failed to demonstrate any time dependent changes. It appears that the 340 nm intensity changes is due to changes in the tryptophan level, and may reflect a factor in the wound healing process.
