Effect of intrabronchially instilled amosite on lavagable lung and pleural cells
…the study. No pleural reaction was seen in the saline instilled group. The inflammatory reactions indicated by the composition of the lavaged cells of the lung represent the in vivo toxicity of intrabronchially instilled amosite. The…

An assessment of the fibrogenic potential of very short 4T30 chrysotile by intratracheal instillation in rats
…structure, and surface charge, the lung tissue reaction differed considerably. Lungs of animals exposed to UICC chrysotile B showed significant pathological alterations as early as 7 days following treatment. The lesions were localized in and around…

Effect of asbestos on the metabolism of vasoactive substances in isolated perfused guinea pig lungs
…The tissue response consisted of both inflammatory reaction of terminal and respiratory bronchioles and diffuse alveolar septal infiltration with interstitial fibrosis. The reaction was characterized at six months by a progressive bronchiolitis obliterans with fibroblastic proliferation…
