    AbstractSerum treatment in vitro with organic solvents (chloroform, ether, toluene) failed to produce an effect on immunoglobulin levels and activity. After chloroform and ether treatment, no complement activity could be determined, with chloroform-treated serum beginning to express anticomplement activity against autologous, allogenic and xenogenic sera. The classical pathway of complement activation (C1, C4, C2, C3) was primarily inhibited, whereas the alternative pathway remained unaffected. Chloroform-treated sera exhibited significantly declined levels of C1-INH, C3 and C4 as well as of circulating immune complexes. Toluene did not influence any of the parameters tested, while ether blocked complement activity without affecting either the concentration or activity of the other components under investigation. The obtained findings are discussed from the aspect of organic solvent applications in preparing immune products and determining immunity indicators in the serum or other biological fluids.
