abstract: Light scattering (90 degrees) of Ehrlich ascites tumor and sarcoma 37 cell suspension in the temperature range 25,60 degrees C was studied (heating velocity was 3 grad/min). It is found that the scattering curve has the peak at 46 degrees C and two plots which are typical of phase transitions in the membranes; the first plot in the range 40-46 degrees C is reversible and the second one at 46-51 degrees C is irreversible. It is proposed that 46 degrees is a critical temperature for the membranes structure stability and viability of the studied cells.
