摘要：
The effects of solar radiation on the motility of the colored ciliate, Stentor coeruleus, have been assessed as a photodynamic model system for hypericism. The organism has been found to be extremely sensitive to solar radiation-a few minutes of unfiltered radiation suffice to arrest motility and decrease the velocity of movement. Removing UV-B and UV-A radiation prolongs the tolerated exposure times. From the present study, the mechanisms of the photodynamic action in S. coeruleus and in hypericin-sensitized reactions have not been resolved in terms of Type I and II mechanisms.
