Russian photosensitizer radachlorine in photodynamic therapy for epibulbar and choroid tumors: experimental studies

摘要

The authors used the Russian agent Radachlorine as a photosensitizer (PS) in photodynamic therapy (PDT) for epibulbar and chorioid tumors. Analyzing the results suggests that the efficacy of Radachlorine used as PS in a correctly adjusted dose in PDT may be high. The optimization of effects in the experiment was observed when Radachlorine was used in a dose of 3 mg/kg with a light radiation dose of 500 mW/cm2 upon 5-min exposure. However, a rapid relapse in some cases indicates the instability of the effect and makes it necessary to make repeated PS injections and PDT sessions.
