Sorrel Extract Reduces Oxidant Production in Airway Epithelial Cells Exposed to Swine Barn Dust Extract In Vitro

Figure 4

Enhanced nitric oxide secretion by cultures of human airway epithelial cells following DE exposure. NHBE cells were pretreated with 20 mM NAC or 1% sorrel followed by a 7-hour 5% DE exposure, and NO₂^- levels were measured in cell-free supernatant using the Griess reagent. value < 0.05 compared to DE. value < 0.001 compared to media. Data are presented as the , .
