Specimens of lung tissue of the two groups were taken and prepared for light microscopic examination.Result: Structural changes were found in the experimental (5-fluorouracil) group compared to the controls, including abnormal alveolar duct, sac, and terminal bronchioles with emphysematous changes in most of the alveoli in addition to peribronchiolitis, perivasculitis, inflammatory cells infiltration and interstitial fibrosis.Conclusion: 5-fluorouracil has toxic effects on the lung tissue resulting in emphysema and interstitial fibrosis.Keywords: 5-fluorouracil, Rat, Lung, Emphesema, Interstitial fibrosis
