abstract：:Cigarette smoke and hydrocortisone acetate (HCA) induce marked abnormalities in lungs of C57BL/6J male mice. In many pulmonary regions of smoke-exposed, HCA-treated animals, alveoli were highly congested with surfactant and flocculent material. In addition, prominent alveolar collapse and septal hypertrophy were commo...
