Sephadex-induced granulomatous alveolitis in rat: effects of antigen manipulation

Am J Ind Med. 1994 Jan;25(1):73-8. doi: 10.1002/ajim.4700250119.

Abstract

A granulomatous alveolitis, with multinuclear cell formation combined with an eosinophilic peribronchiolitis, was achieved in rats by intratracheal administration of sephadex beads (G-200, Pharmacia, Sweden). The pattern of inflammation and the degree of postgranulomatous fibrosis were substantially dampened when the particles were dispersed by ultrasonification. The animals were analyzed with bronchoalveolar lavage and tissue morphology.
