RESUMO

The current study was undertaken to evaluate the effect of combined therapy of gabapentin and pantoprazole against forestomach and pylorus ligation-induced gastric esophageal reflux disease (GERD) in albino Wistar rats. Rats were randomly divided into five groups, each group consisting of six rats, fasted for 24 h, underwent forestomach and pylorus ligation, received normal saline (3 ml/kg, p.o.), normal control, toxic control, pantoprazole (30 mg/kg, p.o.), gabapentin (50 mg/kg, p.o.), or their combination. After 10 h, animals were killed by cervical dislocation and evaluated for pH of gastric content, volume of gastric juice, total acidity, and esophagitis index. Esophageal tissues were further analyzed for biochemical parameters such as superoxide dismutase, glutathione, catalase, thiobarbituric acid reactive substances, and protein carbonyl, and scanning electron microscopy (SEM) and histopathology were used for morphological evaluation. The results show the combination therapy of gabapentin and pantoprazole significantly inhibited the volume of gastric juice and total acidity esophagitis index and significantly increased the pH of gastric juice. Treatment with gabapentin and pantoprazole exhibited maximum antioxidant effect in comparison with monotherapy. Marked protection and restoration of normal morphology was observed through SEM and histopathology in the combination therapy as compared to monotherapy. Finally, it was concluded that combination therapy of pantoprazole and gabapentin has beneficial effect against GERD.

RESUMO

This study was embarked upon to evaluate the effects of pantoprazole and palonosetron on experimental esophagitis in albino wistar rats. Groups of rats, fasted for 36 h, were subjected to pylorus and forestomach ligation, supervened by treatment with normal saline (3 ml/kg, po, sham control), esophagitis control (3 ml/kg, po), pantoprazole (30 mg/kg, po), palonosetron (0.5 mg/kg, po), and their combination. Animals were sacrificed after 12 h and appraised for the volume of gastric juices, total acidity, free acidity, and esophagitis index. Esophageal tissues were further figured out biochemically for markers of oxidative stress and inflammatory mediators. The combination therapy comparably inhibited the esophagitis index (52.86%), gastric volume (66.04%), free acidity (43.76%), and total acidity (42.60%) in comparison with toxic control. The combination therapy also subsidized the biochemical and inflammatory markers to the purview less than toxic control. The morphological changes were scrutinized by scanning electron microscopy and were observed to demonstrate momentous protection by the amalgamation therapy. Combination therapy with pantoprazole and palonosetron flaunted sententious protection against experimental esophagitis.

RESUMO

INTRODUCTION: The present study was undertaken to elucidate the effect of Linum usitatissimum fixed oil on experimental esophagitis in albino rats. METHODS: Group of rats (n = 6), treated with vehicle control (0.9% NaCl, 3 mL/kg, i.p.) or L. usitatissimum fixed oil (1, 2, 3 mL/kg, i.p.) or omeprazole (30 mg/kg, i.p.). Rats were subjected to pylorus and forestomach ligation to induce esophagitis and were compared to a control sham group. Animals were sacrificed after 6 h and evaluated for the gastric pH, gastric volume, total acidity and esophagitis index. Esophageal tissues were further subjected to estimations of sialic acid, collagen, thiobarbituric acid reactive substances, tissue glutathione, catalase and superoxide dismutase. RESULTS: Treatment with fixed oil significantly inhibited the gastric secretion, total acidity and esophagitis index. The oil also altered the levels of sialic acid and collagen towards normal with significant antioxidant activity in esophageal tissues. CONCLUSION: The lipoxygenase inhibitory, histamine antagonistic, antisecretory (anticholinergic) and antioxidant activity of the oil was attributed for its effect in reflux esophagitis.

RESUMO

Se examinó el extracto acuoso y etanólico (100 mg/kg) de Luffa acutangula Linn (frutos) para determinar la actividadantihepatotóxica en ratas druckrey mediante la hepatotoxicidad inducida por tetracloruro de carbono (CCl4)y paracetamol (PCM). Se demostró que el extracto posee un efecto hepatoprotector signifi cativo, ya que reduce losniveles séricos de transaminasas (SGPT y SGOT), fosfatasa alcalina (ALP) y bilirrubina. La signifi cativa actividadhepatoprotectora de Luffa acutangula es comparable a la de la silimarina, agente hepatoprotector estándar, lo quejustifi ca su uso en afecciones del hígado


The ethanolic and aqueous extract (100mg/kg) of Luffa acutangula Linn(fruits) was examined for antihepatotoxic activityin druckrey rats by inducing hepatotoxicity with Carbon tetrachloride(CCl4) and Paracetamol(PCM). The extracthas shown to posses signifi cant hepatoprotective effect by lowering the serum level of transaminases (SGPT & SGOT),Alkaline phosphatase (ALP) and bilirubin. The signifi cant hepatoprotective activity of Luffa acutangula is comparableto that standard hepatoprotective agent silymarin, which justify its use in liver affection
