Abstract

  The present study examined the histological changes in lung tissue induced by single intratracheal instillation on bleomycin in Wistar rats. Animals were treated with bleomycin at the dose of 6.5 U/kg body weight via., single intra-tracheal instillation. Histopathological abnormalities in lungs were assessed on day 21 using hematoxylin and eosin staining and Masson’s trichrome staining. Single intra-tracheal instillation of bleomycin led to the extensive deposition of collagen in peribronchial and perialveolar region, which obliterated the alveolar spaces. Severe lung alveolitis and injury, which was manifested with interalveolar inflammation, thickening alveolar wall, bronchial erosion, and large fibrotic area inconsistently. The results of the present study speculate that inflammation is the forerunner of fibrosis induced by single intra-tracheal instillation of bleomycin.
