Perubahan Histopatologi Paru pada Paparan Debu Batubara Memakai Alat Model 2010
Coal mining on surface ground stimulate to create coal dust exposure equipment on laboratory scale. Optimation of model 2010 coal dust exposure equipment focus on coal dust accumulation and histopathologic of lung. This experimental study was done in control (K), coal dust exposure for 14 days (BB1), and coal dust exposure for 28
days (BB2). Coal dust characterization was done by scanning electron microscope (SEM) and X-ray fluorescence in Physics Laboratory Malang State of University. Histopathologic analysis was done in Pathologic Laboratory Ulin General Hospital. Research was done August−November 2010. Lung SEM showed particle diameter 10 mm and particle accumulated in alveolus. Lung parenchym showed thin alveolus structure (K), thickenning of alveolus and edematous epithelial (BB1), increased edematous and narrower alveolus space (BB2). Epithelial in bronchus
layering by cylindrical and goblet epithelial, inflammation cell (K), elongation of cylindrical epithelial, hyperplasia goblet epithelial and mucous (BB1). Epithelial became thick, more mucous, and epithelial morphology became unclear (BB2). Bronchoalveolus epithelial layering by cylindrical epithelial, minimal goblet cell and inflammation
cell (K). Goblet cell hyperplasia and mucous (BB1). Cylindrical epithelial with goblet cell proliferation, mucous inflammation cell, and fibrosis (BB2). In conclusions, coal dust exposure with model 2010 equipment trigger coal dust accumulation in avelous and histopathologic changes of inflamation, goblet cell hyperplasia, and fibrotic.
