Elastase-induced emphysema in guinea pigs

Description

Pulmonary function changes measured in guinea pigs 4 to 5 wk following intratracheal instillation of crystalline porcine pancreatic elastase resembled comparable changes in humans with moderately severe pulmonary emphysema. Compared with saline-treated controls, elastase-treated animals had increased values for all divisions of lung volume, increased static compliance and prolonged time constants. Since humans with emphysema are especially sensitive to air pollutants, elastase-treated animals may be useful as sensitive animal models in inhalatio toxicology
