Digestion of proteoglycans in porcine pancreatic elastase-induced emphysema in rats.

Abstract

Pulmonary emphysema was induced in rats by a single intratracheal instillation of pancreatic elastase. The short-term effects of elastase instillation on basement membrane components were evaluated using immunohistochemical and biochemical methods. Lung alveoli showed a decrease in heparan sulphate proteoglycan content (especially of its heparan sulphate… (More)
