Abstract Background: Inhalation of Sulfur mustard (HD) will cause lung epithelial inflammation and injury. There are different results from the prophylactic effects of amifostine (AM) on protection of lung epithelial tissue against HD. The aim of this study was to evaluate the prophylactic effects of AM on protection of rat lung tissue exposed to HD. Methods: In this study twenty Albino Wistar adult male rats weighting 200±20 grams were used. Rats were divided randomly into 4 groups (5 rats in each group) as below: Normal saline group (NS), AM group, HD group (0.25% HD) and HD+AM group. Normal saline and HD solution were injected by intra tracheal catheter. Animals in AM and HD+AM groups received AM by intra peritoneal injection for 14 days daily. All rats were killed after 14 days parts of the base of right lungs were removed, fixed and processed for histological evaluation by Toluidine blue, H&E staining and apoptotic cell death study by the TUNEL Apoptosis Detection Kit. In addition, glutathione level was measured in all specimens. Results: No significant differences were revealed between Saline & AM groups in any of the aforementioned tests. Significant reduction of mast cells in lung tissue of the HD+AM group was shown when compared to the HD group. Lung tissue inflammation in the HD group was significantly more severe as compared to HD+AM group. In addition, amifostine in HD+AM group could prevent excess reduction of GSH level. The number of apoptotic cells in the HD group was significantly higher than the HD+AM group. Conclusion: Administration of amifostine before exposure to HD in rats prevents collection of mast cells, and excess reduction of GSH level in lung tissue in addition it can partially reduce pulmonary edema and alveolar cell death apoptosis. KEYWORDS: Sulfur mustard, Lung tissue, Amifostine, Rat.
