596,403 | Ozone exposure of macrophages induces an alveolar epithelial chemokine response through IL-1alpha | Manzer, R; Dinarello, CA; Mcconville, G; Mason, RJ | 2,008 | Ozone is known to produce an acute influx of neutrophils, and alveolar epithelial cells can secrete chemokines and modulate inflammatory processes. However, direct exposure of alveolar epithelial cells and macrophages to ozone (O(3)) produces little chemokine response. To determine if cell-cell interactions might be re... | 0 |
197,786 | Ultrastructural alterations during embryonic rats' lung development caused by ozone | Lopez, I; Sanchez, I; Bizarro, P; Acevedo, S; Ustarroz, M; Fortoul, T | 2,008 | Ozone (O3) is an oxidizing agent that acts on phospholipids, proteins and sugars of cellular membranes producing free radicals, which cause oxidative damages. The O3 exposure has been used as a model to study oxidative stress, in which the respiratory airways represent the entrance to the organism. In this study, ultra... | 1 |

Since cerebellar morphologic disruptions have been reported with prenatal O3 exposure, O3 may have an effect on some neurotransmitter systems, such as monoamines. In order to test this hypothesis, we used 60 male rats taken from either,... | 1 |
