Long-term pulmonary histopathologic changes in rats following acute experimental exposure to chlorine gas.
In this study, we aimed to investigate the long-term histopathologic changes in the lungs of rats exposed to a high concentration of chlorine gas. Twenty-four Sprague-Dawley rats were divided into three groups: the control group (group I) (n = 8), early-examined group (group II) (n = 8), and late-examined group (group III) (n = 8). ⋯ Interstitial fibrosis and thickening of the alveolar septa were observed in group III. These findings suggest that the people using these cleaning agents are at risk of harming themselves, and the victims of chlorine gas injury should be reexamined at a later period since they may have pulmonary damage even after 45 days of exposure.
