The effects of photodynamic therapy (PDT) on the 180-sarcom tumors in some days after treatment were studied at the photo microscope and electro-microscope levels in BALB/c mice bearing 180 sarcom tumors. Animals received intravenous injection of 10 mg/kg of Photofrin and 24h later tumors were treated with 200-350 J/cm2 gold vapor laser light (630 nm). Animals were sacrificed and their tumors removed at time 24, 48, 72h and 7, 14, 21 days after PDT. The results indicated the effects of destruction of the 180-sarcom cells
