Pulmonary toxicity of bleomycin.
Diffuse pulmonary fibrosis is associated with bleomycin administration to humans. The sequential reactions of lung cells to this drug have now been investigated in mice following injection of 20 mg/kg bleomycin twice per week for 4 to 8 weeks. Cytoplasmic and subendothelial edema was first observed in large vessels and by 4 weeks involved the capillaries. The reaction in many animals did not pr...
متن کاملGenetic Requirements for Protection Against Bleomycin Toxicity
Bleomycin is known to cause double strand breaks in vitro. Little is known, however, about its mechanism of genotoxicity in vivo. One way to probe the mechanism of genotoxicity of a DNA damaging agent in vivo is to compare the relative sensitivities of a wild type Escherichia coli strain to a panel of isogenic repair deficient mutants. If the pathway defective in the mutant is known (e.g., base...
متن کاملUltrastructural study of pulmonary bleomycin toxicity.
Ultrastructural manifestations of bleomycin A2 toxicity in the human lung were studied in three patients. In addition to the appearance of nucleolar fibrillar centers, an increase in membranous, beaded, and granular nuclear bodies was found in nuclei of type 1, type 2 alveolar epithelial cells, and interstitial fibroblasts in all treated patients. Few such nuclear bodies were found in specimens...
متن کاملSynthetic liposomes are protective from bleomycin-induced lung toxicity.
Idiopathic pulmonary fibrosis is a devastating disease characterized by a progressive, irreversible, and ultimately lethal form of lung fibrosis. Except for lung transplantation, no effective treatment options currently exist. The bleomycin animal model is one of the best studied models of lung injury and fibrosis. A previous study using mouse tumor models observed that liposome-encapsulated bl...
متن کاملBleomycin induced pulmonary toxicity in patients with germ cell tumours.
BACKGROUND Bleomycin is a cytotoxic drug used in treatment of Germ Cell Tumours (GCTs) and is associated with pulmonary toxicity. Bleomycin pulmonary toxicity (BPT) manifests predominantly as pulmonary fibrosis, organising pneumonia (OP) or Nonspecific Interstitial Pneumonitis (NSIP). Our objectives were to determine the incidence of BPT, describe the common HRCT patterns of pulmonary toxicity ...
