Fig. 3From: Mechanisms of pulmonary disease in F344 rats after workplace-relevant inhalation exposure to cross-linked water-soluble acrylic acid polymersRepresentative macroscopic and microscopic photographs of rat lungs after repeated inhalation exposure to CWAAP-A. Results of the high-concentration intermittent inhalation experiment. Representative lesions of the rat lung exposed to 40Â mg/m3 CWAAP-A are shown after hematoxylin and eosin (HE) and Periodic acid Schiff (PAS)-Diastase staining. The boxed areas in the upper and middle panels of 3B outline multifocal lesions after the 18-week recovery periodBack to article page
