GLUCOSE ADMINISTRATION AUGMENTS IN VIVO UPTAKE AND PHOTOTOXICITY OF THE TUMOR‐LOCALIZING FRACTION OF HEMATOPORPHYRIN DERIVATIVE

Abstract
Rhabdomyosarcoma tumors in rats made hyperglycemic by multiple injections of glucose exhibited a transient decrease in pH and an increased ability to accumulate derivatives of hemato‐porphyrin (HPD). Photoradiation of tumors in glucose/HPD‐treated animals produced a greater cell kill than in galactose/HPD‐treated controls. A therapeutic benefit of glucose administration in conjunction with HPD‐phototherapy is suggested.
