3, preincubation of hypodense eosinophils with ascitic fluids of BB10 induced a high level of inhibition of IgE-dependent cytotoxicity, and a dose-dependent inhibition was obtained with the purified IgM fraction of BB 10. Student's t test for paired experiments revealed highly significant results (p < 0.001, n, 16 experiments), except in the case of the lower dose of purified BB10.
