[Comparison of photodynamic effect with respect to human and rabbit erythrocytes].

Parameters of photoinduced lysis are studied for human and rabbit erythrocytes (photosensibilizer--Radachlorin, the light source--Shuttle HeNe lazer, lambda = 633 nm). The higher sensitivity to irradiation is revealed for rabbit erythrocytes. Treatment of erythrocytes with trypsin showed the surface proteins in human cells to produce a protective effect. Trypsynization of rabbit erythrocytes produced the opposite action--the rate of photohemolysis increased. Results of the study indicate the differences in sensitivity to the photoinduced lysis of erythrocytes of different species and participation of erythrocytes proteins in the effect of photohemolysis.
