Abstract
Irradiation of red blood cell lysate with a N-2 laser (337 nm) was observed to induce oxidation of hemoproteins, This process showed a strong dependen ce on the concentration of red blood cell lysate and the dose of radiation. Studies of mechanisms and experiments with deoxygenated red blood cell lys ate rule out involvement of any reactive oxygen species and suggest that th e process is not a photodynamic reaction.
