All v.70 v.71 v.72 v.73 v.74 Photochemistry and Photobiology, Vol. The osmotic fragility of the erythrocyte membrane to hypotonic solutions is investigated theoretically. The fragility curves exhibit a strong transmittance rise. This variation is assumed to result from changes in the scattering properties of erythrocytes under dialysis resulting from swelling and hemolysis. The refractive indices of erythrocytes are obtained through the Lorentz-Lorenz relation based on hemoglobin and water contents.
Hemolysis alone causes the abrupt sigmoidal increase of the collimated transmittance with time.
