✦ Synopsis

Using a spectrophotometer equipped with an internal integrating sphere, the absorption (pa) and the reduced scattering (ps0 coefficients of ex vivo human colon tissues were evaluated from reflectance and transmittance measurements. pa and ps' varied from 47.7 to 1.0 cm-' and from 14.2 to 6.2 cm-', respectively, on passing from 300 nm to 800 nm. These results can be used to estimate the optical penetration depths when photodynamic therapy or light-induced fluorescence procedures are used.
