Abstract

SUMMARY Human mononuclcar leucocytes (MNL) or the adherent fraction (monocytes) produced tumour necrosis factor-alpha (TNF-α) (by EL1SA) in culture when stimulated with killed Staphylococcus aureus. The bisbenzylisoquinoline alkaloid, tetrandrine inhibited the capacity of MNL and monocytes to produce TNF-α at a concentration range of 0·1 to 5 μg/ml. Tetrandrine may be potentially useful in the treatment of inflammatory diseases in which TNF-α plays a major role.
