When rat bone marrow macrophages were incubated with acetyl lignin (EP3) in the presence of a 10% solution of fetal bovine serum, the macrophages secreted tumor necrosis factor (TNF-alpha) in a dose-dependent manner. This was followed by macrophage multinucleation. EP3 was found to have a significant effect on TNF-alpha secretion at a minimum dose of 5 micrograms/ml and produced no significant further increase at levels above 50 micrograms/ml, while multinucleation was most active at 10 micrograms/ml. However, multinucleation did not occur at higher concentrations of EP3 (50 micrograms/ml and 100 micrograms/ml). Secretion of TNF-alpha was significantly reduced in the absence of fetal bovine serum, whereas multinucleation was very active, starting after 6 h of incubation. At concentrations of 100 micrograms/ml, sulfonyl lignin (LS) and dextran sulfate (DS) only induced low levels of TNF-alpha secretion from macrophages, but induced active multinucleation. The multinucleation induced by addition of LS or DS was inhibited by further addition of EP3. Thus, macrophage multinucleation was most active when a low level of TNF-alpha was secreted from the macrophages.
