Fig. 3From: Reduced bronchoalveolar macrophage phagocytosis and cytotoxic effects after controlled short-term exposure to wood smoke in healthy humansPhagocytosing cells in BAL. A: Phagocytosing ability measured in BAL cells after air and wood smoke exposures. Two different treatments; negative control (cells put on ice), positive control cells (incubated in 37 degrees Celsius). Whiskers indicate minimum to maximum value. B: Viability in BAL cells measured after phagocytosis evaluation. A statistically significant increase in dead cells was found (p = 0.02) among BAL cells exposed wood smoke. Red lines indicate median values and * indicates p < 0.05, calculated using the Wilcoxon signed-rank testBack to article page
