The purpose of the present study was to gain new insight regarding the role membrane permeabilization plays in the photosensitization-induced increase in intracellular calcium concentration. During continuous rose bengal photosensitization we monitor

Since the physiological relevance of 1O2 independent of photosensitization has been controversial, we review proposed reaction mechanisms for its extracellular production in vivo and discuss the relevance of this production to oxidative stress. We co

The effects of reactive oxygen species, especially as generated by photosensitizers and light, may serve as a model for light-induced effects relying on endogenous chromophores. Early events in the series of reactions initiated by these processes are

Photosensitization using Rose Bengal (RB) modifies membrane ionic currents and kills cultured mouse pituitary, GH3, cells. Here we investigate the dose-response relationship for ionic current modification and for cell killing to assess a possible cau

We reported previously that singlet oxygen (1O2), generated by illuminating the photosensitizer rose bengal (RB), suppressed the delayed rectifier potassium current (IK) in single frog atrial cells. Considering the brief lifetime of 1O2, one might ex

Photosensitized modification of ionic leak current and potassium current was studied in frog cardiac atrial cells using whole cell patch clamp techniques. Rose bengal (RB) and menadione (MQ) were used as photosensitizers. Separate photophysical studi

Cardiac myocytes were isolated from the atria of frogs (Rana pipiens) and whole cell potassium (IK) and "leakage" (Ileak) currents were monitored using the patch clamp technique. Cells were photosensitized by exposure to Rose Bengal (0.125-0.5 microM
