Figure 4From: Lung inflammation following a single exposure to swine barn airIncreased granulocyte numbers following a secondary challenge. Rats exposed to the barn and challenged with LPS showed more number of granulocytes in the lung septum compared to barn exposed and saline challenged and LPS challenged unexposed rats. Within unexposed rats, LPS challenged rats showed more granulocytes compared to saline challenged ones (*, P < 0.001).Back to article page
