[Preliminary data concerning cross-reacting anticardiolipin antibodies as potential inhibiting endotoxin activity factors].
In analyzed synovial fluids, suspected for endotoxin presence, the presence of endotoxin done was proved by LAL-test in 21 synovial fluids /42%/ and in 12 of 20 /60%/ the presence of endotoxin inhibiting substances /IS/ was proved. Because many parameters /like presence CIC, anti-LPS, KDO/ indicates that in the group of LAL-negative /IS/ - positive synovial fluids the presence of endotoxin is very possible, IS have been removed /by heating to 100 degrees C/ and after that the endotoxin activity was shown in about 27% of synovial fluids. Additional analysis of the Cohn fraction /prepared by ammonium sulfate precipitation/ confirmed the presence in the gamma and alpha and beta fractions a weak IS activity /in a dose dependent manner. No IS activity, have been shown yet in the fraction of affinity purified aCl antibodies.
