Inhibition Of Cytochrome P-450 But Not Neutrophil Depletion Prevents The Pulmonary Toxicity Associated With 1-Nitronaphthalene, Steven Michael Green
Inhibition Of Cytochrome P-450 But Not Neutrophil Depletion Prevents The Pulmonary Toxicity Associated With 1-Nitronaphthalene, Steven Michael Green
Masters Theses
1-Nitronaphthalene (1-NN) is an environmental contaminant that has been shown to cause pulmonary toxicity in rodents. To examine the contribution of cytochrome P-450 to the metabolism and subsequent toxicity of 1-NN, rats were pretreated with chloramphenicol, a suicide substrate of P-450. To determine if inflammation plays a role in 1-NN toxicity, rats were pretreated with cyclophosphamide to deplete neutrophils. In both experiments, morphological analysis of the lower airways was performed with light and electron microscopy. A second group of animals was examined for biochemical indicators of inflammation and cell damage. The parameters examined were cell content, protein content and lactate …
