Effect ofPerilla frutescensFixed Oil on Experimental Esophagitis in Albino Wistar Rats

Abstract

The present study was undertaken to elucidate the effect ofPerilla frutescensfixed oil on experimental esophagitis in albino rats. A group of rats (n=6), treated with control vehicle (0.9% NaCl in double distilled water, 3 mL/kg, i.p.) andPerilla frutescensfixed oil (100%) (1, 2, and 3 mL/kg, i.p.), or pantoprazole (30 mg/kg, i.p.), were subjected to pylorus and forestomach ligation. Animals were sacrificed after 6 h and evaluated for the gastric pH, volume of gastric juices, total acidity, esophagitis index and free acidity. Esophageal tissues were further subjected to estimations of TBARS, GSH, catalase, and SOD. Treatment with fixed oil significantly inhibited the gastric secretion, total acidity, and esophagitis index. The oil also helped to restore the altered levels of oxidative stress parameters to normal. The present study also makes evident thein vitroantihistaminic and anticholinergic activity of alpha linolenic acid (ALA) (18 : 3,n−3) on isolated rat ileum preparation. The lipoxygenase inhibitory, histamine antagonistic, antisecretory (anticholinergic), and antioxidant activity of the oil was attributed for its efficacy in reflux esophagitis.
