PAS-positive inclusions in the alveolar type II cells of the caprine lung.
Histochemical analysis of inclusions in the alveolar type II cells was done with the alcian blue-PAS technique. PAS-positive inclusions, which were absent in the sheep and buffalo, were detected in the alveolar type II cells of the goat lung. Mixed diamine-sodium chloride did not stain these inclusions which also showed orthochromatic blue reaction with toluidine blue. The high percentage of alveolar type II cells showing these inclusions suggested that this difference could be explained by the environmental habitat of the goat.
