A. PMN counts were significantly higher in all injured groups. However, HAGE animals had higher PMN counts than the LAGE animals after gastric aspiration (p < 0.01). B. Macrophage counts in the BAL exhibited a completely different pattern, as compared to that of PMN. In animals with gastric aspiration, the dietary AGEs decreased the numbers of alveolar macrophage numbers, as compared with LAGE group (p < 0.01). However, gastric aspiration did not affect the macrophage counts.
