The Role of Radiation in Photodynamic Action

G. CALCUTT 1

1 Department of Cancer Research, Mount Vernon Hospital and the Radium Institute, Northwood, Middlesex, England

It has been demonstrated that, within certain limits, the radiation of cultures of Paramecium bursaria, which had been kept in the dark, with wave-lengths greater than 3300 A., facilitates a subsequently elicited photodynamic response. A period of darkness following the pre-irradiation allows of a return to the normal condition. The role of radiation in the mechanism of photodynamic action is discussed.
