Background: Peptic ulcer disease is a non-malignant, mucosal lesion of the stomach or duodenum. The mucosal defect reaches the muscularis mucosa and sometimes, beyond causing life threatening complications, including haemorrhage, perforations, gastrointestinal obstruction and malignancy.Methods: The animals were pre-treated with omeprazole 20 mg/kg and 300 mg/kg of Capparis cartillaginea decne orally for 14 days. On the 15th day, ulcers were induced using indomethacin 30 mg/kg and 4 hours post ulcer induction, they were sacrificed. Ulcer index, pH, total acidity and volume were determined.Results: Extensive lesions were seen in indomethacin ulcerated rats with mean ulcer score of (1.260±0.18). In comparison, there were minimal areas of erosion on animals pre-treated with omeprazole (0.14±0.025) and plant extracts (0.280±0.097). Indomethacin-induced ulcer treated animals showed the highest volume of gastric juice output (3.14±0.21 ml), whereas the animals pre-treated with omeprazole had lower gastric juice output (2.20±0.2 9ml). This was comparable to animals pre-treated with the plant extract (1.80±0.13 ml). The pH was high in animals pre-treated with omeprazole (5.02±0.53). This was also seen in animals pre-treated with the extract (4.82±0.31). This was in comparison to the low pH seen in indomethacin ulcerated animals (2.20±0.16). Indomethacin-induced ulcer treated animals showed high levels of total acidity (88.64±1.71 mEq/L). Whereas the animals pre-treated with omeprazole had lower total acidity (55.26±3.77 mEq/L), which was also mirrored in animals pre-treated with the plant extracts (61.44±2.42 mEq/L).Conclusions: The extracts of Capparis cartillaginea decne showed anti-ulcer effect on indomethacin induced ulcers in Wistar rats.

Peptic ulcer disease is an injury of the alimentary tract that leads to a mucosal defect reaching the submucosa. Alpha-lipoic acid (ALA), a natural potent antioxidant, has been known as a gastroprotective drug yet its low bioavailability may restrict its therapeutic efficacy. This study aimed to formulate and optimize ALA using a self-nanoemulsifying drug delivery system (SNEDDS) with a size of nano-range, enhancing its absorption and augmenting its gastric ulcer protection efficacy. Three SNEDDS components were selected as the design factors: the concentrations of the pumpkin oil (X1, 10–30%), the surfactant tween 80 (X2, 20–50%), and the co-surfactant polyethylene glycol 200 (X3, 30–60%). The experimental design for the proposed mixture produced 16 formulations with varying ALA-SNEDDS formulation component percentages. The optimized ALA-SNEDDS formula was investigated for gastric ulcer protective effects by evaluating the ulcer index and by the determination of gastric mucosa oxidative stress parameters. Results revealed that optimized ALA-SNEDDS achieved significant improvement in gastric ulcer index in comparison with raw ALA. Histopathological findings confirmed the protective effect of the formulated optimized ALASNEDDS in comparison with raw ALA. These findings suggest that formulation of ALA in SNEDDS form would be more effective in gastric ulcer protection compared to pure ALA.

Background: Peptic ulcer disease remains endemic in our society affecting about four million people every year worldwide. Hannoa klaineana is used traditionally in the treatment of various gastrointestinal diseases including ulcer.Aim: This study aims at evaluating the gastroprotective effect of ethylacetate fraction of the leaves of Hannoa klaineana (Simaroubaceae).Methods: The gastroprotective effect of ethylacetate fraction of the Hannoa klaineana (50, 100 and 200mg/kg b.wt) was evaluated using aspirin and histamine induced ulcer models.Results: In aspirin-induced ulcer model, the ethylacetate fraction of the Hannoa klaineana demonstrated significant (p<0.001) decreased in mean ulcer index with the maximum protective effect (99.84%) at 200 mg/kg against the gastric damages. While histamine-induced ulcer model, the solvent fraction significantly (p<0.001) decreased mean ulcer index with the protective effect up to 99.83% against the gastric lesions. In both models, a significant (p<0.001) increased in pH value coupled with significant (p<0.001) decreased in gastric volume, free and total acidity in rats pre-treated with varying doses of the ethylacetate fraction was found.Conclusion: The mechanism of gastroprotective effects of ethylacetate fraction of the Hannoa klaineana could be attributed to its ability to stimulate prostaglandins secretion or possess prostaglandins like-substances or suppression of histamine-induced vasospastic effect and gastric secretion.

The present study was conducted to investigate the protective effect of the dried berries of Myrtus communis L. in gastric ulcer against ethanol, indomethacin and pyloric ligation induced models in Wistar rats. Two doses of aqueous extracts of M. communis (AE 1 and AE2) at the dose 105 and 175 mg/kg, respectively, and methanolic extracts (ME1 and ME2) at the dose of 93 and 154 mg/kg, respectively, were administered orally to animals prior to the exposure of ulcerogens. The parameters taken to assess anti-ulcer activity were ulcer index, gastric juice volume, gastric pH, total acidity, gastric wall mucus and histopathological studies. Oral administration of AE1 and AE2 significantly reduced the ulcer index in all models of ulcers. Low dose of aqueous extract and high dose of methanolic extract of M. communis exhibited more significant effect in comparison to omeprazole (standard drug) in ethanol-induced ulcer model. Both the doses of aqueous and methanolic extracts also reduced the gastric juice volume, total acidity and increased the gastric pH and gastric wall mucus content in all the models of ulcers used in the present study. Histopathological examinations of gastric tissues of rats treated with the aqueous and methanolic extracts in indomethacin-induced ulcer exhibited significant ulcer-protective effect at both the dose levels.

Objective: The present study was carried out to investigate the role of curcumin in osteoarthritis when it is used as an adjuvant to diclofenac sodium.Methods: Osteoarthritis (OA) was induced by administering nalidixic acid 400 mg/kg. Animals (Female rats) were divided into 5 groups each containing 6 animals. Group I was considered as control, group II in which the animals were induced with osteoarthritis with nalidixic acid and were given no treatment. Group III in which osteoarthritis induced animals were treated with diclofenac sodium by the oral route. Group IV osteoarthritis induced animals were treated with the combination of diclofenac sodium and curcumin and group V animals were pre-treated with curcumin and then induced with osteoarthritis. Parameters like ulcer area, ulcer index, free acidity, total acidity, the volume of gastric juice were estimated. Histopathological studies were also carried out.Results: The data of our study shows that nalidixic acid has not shown much effect on the gastric parameters in group II animals. The ulcer index, free acidity, total acidity and gastric juice volume were increased significantly (p<0.001) in group III and decreased in group IV animals (p<0.05) when compared to group I control animals. Group V animals pretreated with curcumin have shown fewer incidences of gastric ulcers and other ulcerative parameters non significantly. Histopathology also suggests a low incidence of ulcers in group IV and group V.Conclusion: It demonstrates that curcumin when used along with the conventional NSAIDs as an adjuvant therapy, has a role in treating osteoarthritis effectively.

Peptic ulcer disease is an injury of the alimentary tract that leads to a mucosal defect reaching the submucosa. This study aimed to formulate and optimize omega-3 oil as a self-nanoemulsifying drug delivery system (SNEDDS) to achieve oil dispersion in the nano-range in the stomach to augment omega-3 oil gastric ulcer protection efficacy. Three SNEDDS components were selected as the design factors: the concentrations of the oil omega-3 (X1, 10–30%), the surfactant tween 20 and Kolliphor mixture (X2, 20–40%), and the cosurfactant transcutol (X3, 40–60%). The mixture experimental design proposed twenty-three formulations with varying omega-3 SNEDDS formulation component percentages. The optimized omega-3 SNEDDS formula was investigated for gastric ulcer protective effects by evaluating the ulcer index and by the determination of gastric mucosa oxidative stress parameters. Results revealed that optimized omega-3-SNEDDS achieved significant improvement in the gastric ulcer index in comparison with pure omega-3 oil. Histopathological findings confirmed the protective effect of the formulated optimized omega-3 SNEDDS in comparison with omega-3 oil. These findings suggest that formulation of omega-3 in the form of a SNEDDS would be more effective in gastric ulcer protection than the administration of omega-3 as a crude oil.

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.

Background: To evaluate the antiulcer activity of ethanolic leaves extract of Saraca indica against ethanol, pylorus ligature and indomethacin in albino rats. Materials and Methods: Ulcer was produced by ethanol, pylorus ligature and indomethacin in albino rats. Five groups (n=6) of rats were orally pre-treated with carboxymethyl cellulose solution, and ranitidine (80 mg/kg) respectively. In ethanol induced ulcer, the animals were treated with 200 and 400 mg/kg b.w. ethanolic leave extracts of Saraca indica in 0.3% CMC solution, 60 minutes before oral administration of absolute ethanol to produce gastric mucosal injury. In indomethacin induced ulcer, the drug was administered orally at the dose of 30 mg/kg b.w. After 7-9 hours of administration of indomethacin (30 mg/kg); the animals were sacrificed with high doses of anesthesia. In the pylorus ligature method, volume of free acidity, gastric secretion, pH and total acidity were estimated. In all three models, the ulcer index and % protection were estimated. Results: The anti ulcer activity of ethanolic leave extracts of Saraca indica in ethanol, indomethacin and pylorus ligature models is evident from the significant (P<0.001) reduction in ulcer index. In pylorus ligature model, significant (P<0.001) reduction in total acidity gastric volume and increase in pH were observed when compared with the standard drug. Conclusion: Ethanolic leave extracts of Saraca indica were found to be significantly protective against ethanol, indomethacin and pylorus ligature induced gastric ulcers in the experimental albino rats. The result obtained suggest that ethanolic leave extracts of Saraca indica possesses significant anti-ulcer activity.
