Figure 3From: The role of the 5-hydroxytryptamine pathway in reflux-induced esophageal mucosal injury in ratsSerotonin (5-HT) content (ng/ml) in the esophageal tissue of rats with reflux esophagitis (RE) and in NERD rats. 5-HT levels were significantly higher in the esophageal tissue of rats with RE compared to controls (*P < 0.05). 5-HT content was significantly lower in the esophageal tissue of NERD rats than those with RE (#P < 0.05).Back to article page
