Ingestion of omega-3 fatty acid inhibited ileum mucosa damage caused by 5-FU. a Normal histological aspects in the ileum mucosa were observed 24 h after 5-FU injection in all groups. b Increased cell infiltration in the lamina propria was observed in the mice that developed mucositis and mucosal architecture disruption was also observed 72 h after 5-FU injection. Bar = 100 μm. The slices were stained with H&E. 100 ×
