Chronic Inflammation and Tumor Formation in Rats After Intratracheal Instillation of High Doses of Coal Dusts, Titanium Dioxides, and Quartz.

abstract：:Elastolysis, collagenolysis and gelatinolysis are essential in the pathogenesis of tobacco smoke-induced emphysema; however, these activities have been scantily studied in emphysema secondary to woodsmoke. The aim of this study was to analyze elastolysis, collagenolysis and gelatinolysis, MMP-1, MMP-2, and MMP-9 expre...
