The generation of nitric oxide by cultures of macrophages: unstimulated (described as DMEM), stimulated by LPS (LPS), stimulated by AMP neutrophil extract (AMP) and stimulated by dexamethasone (DEX), after 24 h, 3 days and 5 days of incubation at 37 °C and 5% CO₂. p-values calculated for LPS, AMP, and DEX groups were compared with (Student t-test) to unstimulated cultures (DMEM) and were <0.05. The data are presented as the mean ± SE from six rabbits in duplicate experiment
