Effect of rutin against gastric esophageal reflux in experimental animals.

CONTEXT: The present study was undertaken to elucidate the effect of rutin against gastric esophageal reflux in experimental animals.

METHODS

Groups of rats, fasted overnight received normal saline (3 ml/kg, sham control) or esophagitis control (3 ml/kg, normal saline) or pantoprazole (30 mg/kg) or rutin (50 and 100 mg/kg) were subjected to pylorus and forestomach ligation. Animals were sacrificed after 12 h and scrutinized physiologically (gastric pH, total acidity, free acidity and esophagitis index), biochemically (TBAR's, SOD, catalase, GSH and protein carbonyl) and morphologically. The esophageal tissues were also inquested for the presence of proinflammatory (IL-2 and IL-1β) and immunoregulatory (IL-4 and IL-6) cytokines.

RESULTS

The results demonstrated momentous physiological, biochemical and morphological protection imparted by rutin. The rutin also restored the altered levels of proinflammatory and immunoregulatory cytokines, which further strengthens the implication of rutin in GERD.

CONCLUSION

The beneficial effects as observed in the current experiment could be accredited to the antioxidant and anti-inflammatory (through inhibition of COX and LOX) property of rutin.
