Effects of IFN-γ and l-NMMA on (a) mast cell serotonin release and (b) peritoneal cell nitrite production. Peritoneal cells were cultured for 24 hr with IFN-γ (100 ng/ml) or l-NMMA (0·1 mm), both compounds in combination, or with neither compound (control cells). At the end of the culture period supernatant medium was removed for measurement of nitrite, and the cells were washed and challenged with anti-IgE for measurement of serotonin release. Results are means±SEM for four experiments. *P <0·001 compared to control cells.
