Production of Nitrite by horse macrophages. Alveolar and peritoneal cells were seeded at 106 cells/ml and left to rest overnight. The next day non-adherent cells were washed away and cell were stimulated by 100 ng/ml of LPS for 0 h and 6 h in presence of HS. Mouse macrophage RAW 274.1 was used as control.
