Objectives : This study was to evaluate inhibitory effects of Naegwan-acupuncture(PC6) on acute RE(reflux esophigitis) rat induced by pylorus and forestomach ligation operation.
Methods : Twenty seven SD rats were divided three groups (intact normal rat; RE control rat; RE control rat respectively stimulated by Naegwan point(PC6)). All rats was fasted for 18 h but free water, we induced RE by pylorus and forestomach ligation operation. Six hour after the operation, rats were sacrified, collected bloods in the abdominal vein, dissected a esophagus and stomach. The stomach was washed a 1 ml PBS to research gastric volume, pH, acidity and mucin release of gastric juice, esophagus was cut longitudinally and pictured a innter mucosa area to research damages in esophagus. The proinflammatory cytokine and chemokine including IFN-γ, TNF-α, IL-1β, IL-6 and MCP-1 were analyzed by ELISA kit.
Results : 1. Significantly, death rate of PC6 acupuncture rat group was decreased compared to that of RE control group.
2. Gastric Volume, gastric injury and esophageal mucosa demage were decreased significantly, too.
3. Compared with RE, all of the proinflammatory cytokine and chemokine analyzed in serum of PC6 were decreased remarkably. Especially, there were significant meanings TNF-α, IL-6 and MCP-1 in serum of PC6 were decreased.
Conclusion : The results suggest that antiinflammatory and protecting effects of PC6 could attenuate the severity of reflux esophagitis and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.
