Experiments were conducted in vitro on rabbits to study the effect of emulsions based on composition of carbon perfluorides (decalin perfluoride/methyl cyclohexyl piperidine perfluoride) and proxanol (P-268) on the blood complement system. It is shown that despite preservation of the composition some emulsions activate complement others fail to do this. Intravenous infusion of complement-activating emulsion in a test-dose leads to early neutropenic reaction in the peripheral blood of rabbits and intensified power of low frequency rhythms in the electrocorticogram.
