COMPARISON OF THE EFFICACY OF PULSED AND CONTINUOUS‐WAVE RED LASER LIGHT IN INDUCTION OF PHOTOCYTOTOXICITY BY HAEMATOPORPHYRIN DERIVATIVE

Abstract
Abstract—The efficiency of pulsed and continuous wave laser light to induce photodynamic activity in haematoporphyrin derivative (Hpd) was compared in two systems, a tissue culture assay and a transplantable mouse tumour. No difference was found.
