The present study was undertaken to elucidate how the plastic properties of model membranes from native lipids of different tissues of rats change in the course of Macrovipera lebetina obtuse (MLO), Montivipera raddei (MR) and Naja kaouthia (NK) venoms processing. The presence of viper venom in organism lead to increasing of the electrical resistance of BLMs from liver and muscle lipids approximately on a sequence, while the BLMs from brain lipids has not shown a noticeable differences of plastic properties compare the control. The same concentration of cobra venom leads to decreasing of electrical resistance of BLMs from 1011 Ohm till 108 Ohm. The low concentration of venom leads to appearance of channel activity. Especially it is noticeable in liver lipids in media of bivalen ions.
