Additional, the lung histopathological sections that were stained with hematoxylin and eosin (H E), demonstrated enhanced thickness of bronchioles in the placebo group compared to the challenge group. Histological evaluation performed by three different pathologists, employing comprehensive system of histopathologic examination [18]. The histopathologic indices that had been taken into account, scores to the extent of epithelial thickening, extracellular discharge and alveolar inflammation (Figure 6F). The interpretations of data measurements had been reported as ordinal (i.e., regular = 0, mild = 1, mode.
