Gastric anti-ulcerative and anti-inflammatory activity of metyrosine in rats

In this study, the anti-inflammatory and anti-ulcerative effects of metyrosine, a selective tyrosine hydroxylase enzyme inhibitor, were investigated in rats. For ulcer experiments, indomethacin-induced gastric ulcer tests and ethanol-induced gastric ulcer tests were used. For these experiments, rats were fasted for 24 h. Different doses of metyrosine and 25 mg/kg doses of ranitidine were administered to rats, followed by indomethacin at 25 mg/kg for the indomethacin-induced ulcer test, or 50% ethanol for the ethanol-induced test. Results have shown that at all of the doses used (50,100 and 200 mg/kg), metyrosine had significant anti-ulcerative effects in both indomethacin and ethanol-induced ulcer tests. Metyrosine doses of 100 and 200 mg/kg (especially the 200 mg/kg dose) also inhibited carrageenan-induced paw inflammation even more effectively than indomethacin. In addition, to characterize the anti-inflammatory mechanism of metyrosine we investigated its effects on cyclooxygenase (COX) activity in inflammatory tissue (rat paw). The results showed that all doses of metyrosine significantly inhibited high COX-2 activity. The degree of COX-2 inhibition correlated with the increase in anti-inflammatory activity. In conclusion, we found that metyrosine has more anti-inflammatory effects than indomethacin and that these effects can be attributed to the selective inhibition of COX-2 enzymes by metyrosine. We also found that adrenalin levels are reduced upon metyrosine treatment, which may be the cause of the observed gastro-protective effects of this compound.     

Evaluation of anti-ulcer activity of Samanea saman (Jacq) merr bark on ethanol and stress induced gastric lesions in albino rats

Objective:

To evaluate the antiulcer activity of Samanea saman (Jacq) Merr bark on ethanol and stress induced gastric lesions in albino rats.

Materials and Methods:

Gastric lesions were induced in rats by oral administration of absolute ethanol (5 ml/kg) and stress induced by water immersion. The antiulcer activity of methanolic extract of Samanea saman (Jacq) Merr bark (100 mg/kg, 200 mg/kg, 400 mg/kg) was compared with standard drugs. The parameters studied were ulcer index, gastric juice volume, pH, free acidity and total acidity.

Result:

Samanea saman (Jacq) Merr showed a dose dependent curative ratio compared to ulcer control groups. The extract at 400 mg/kg showed significant anti ulcer activity which is almost equal to that of the standard drug in both models. The volume of acid secretion, total and free acidity was decreased and pH of the gastric juice was increased compared to ulcer control group.

Conclusions:

The present study indicates that Samanea saman (Jacq) Merr bark extracts have potential anti ulcer activity.

A reliable method for the production of antral gastric ulcer by a combination of 2-deoxy-D-glucose, aspirin and ammonia in rats.

In order to establish a reliable method for the production of gastric antral ulcer in rats, combined treatments with three factors: a vagal stimulant, a mucosal barrier breaker and a necrotizing agent were investigated. By the combined administration of 2-deoxy-D-glucose (2-DG; 200 mg/kg, i.v.), aspirin (100-400 mg/kg, p.o.) and hydrochloric acid (0.15 and 0.35 N, 0.5-1.5 ml/100 g, p.o.) or ammonia solution (0.5-1.0%, 0.5-1.5 ml/100 g, p.o.), gastric lesions were prominently induced in sites of both the corpus and antrum on day 2. The largest antral ulcer was induced by the combination of 2-DG (200 mg/kg), aspirin (200 mg/kg) and ammonia solution (1%, 10 ml/kg); and the mean antral ulcer index (mm2) was 43.1 +/- 4.4 and the incidence was 100%. The antral ulcer was found to penetrate the muscularis mucosae and still observed on day 21 and day 28 after ulcer induction in a few cases. From these findings, it was indicated that this antral ulcer would be a useful model for studying the etiology and therapy of gastric ulcer disease.     

Low-dose furazolidone in triple and quadruple regimens for Helicobacter pylori eradication

BACKGROUND: Furazolidone-based regimens for the eradication of Helicobacter pylori are low cost and effective. Unfortunately, the usual dose of furazolidone is not tolerable in many patients. Lower doses of furazolidone are expected to cause fewer adverse effects. AIM: To investigate the efficacy of low-dose furazolidone in the eradication of H. pylori. METHODS: One hundred and fifty patients with duodenal ulcer and H. pylori infection were randomly assigned to one of three treatment groups: omeprazole 20 mg b.d., amoxicillin 1000 mg b.d. and furazolidone 100 mg b.d. for 14 days (OAF); omeprazole 20 mg b.d., amoxicillin 1000 mg b.d., furazolidone 100 mg b.d. and bismuth subcitrate 240 mg b.d. for 14 days (OABF1); or omeprazole 20 mg b.d., amoxicillin 1000 mg b.d., furazolidone 200 mg b.d. and bismuth subcitrate 240 mg b.d. for 14 days (OABF2). RESULTS: Of the 150 patients, 145 completed treatment. The intention-to-treat and per protocol eradication rates were 54% (27/50), 72% (36/50) and 92% (46/50) for the OAF, OABF1 and OABF2 groups, respectively. The OAF and OABF1 groups showed significantly lower eradication rates than the OABF2 group (P<0.001 and P<0.01, respectively). CONCLUSIONS: Triple and quadruple furazolidone-based H. pylori eradication regimens do not yield acceptable success rates when a low dose of furazolidone (100 mg b.d.) is used.     

A new quadruple therapy for Helicobacter pylori using tripotassium dicitrato bismuthate, furazolidone, josamycin and famotidine

BACKGROUND: In our previous study, a triple therapy using tripotassium dicitrato bismuthate (TDB), josamycin and furazolidone achieved a suboptimal cure rate of Helicobacter pylori infection. AIM: To investigate whether the addition of an antisecretory agent raises the cure rate using this regimen. METHODS: One hundred and twenty H. pylori positive patients with peptic ulcer disease or functional dyspepsia were randomly assigned to receive 1-week quadruple therapy of TDB 240 mg b.d., furazolidone 100 mg b.d., josamycin 1000 mg b.d. and famotidine 20 mg b.d. (BFJF group), or triple therapy of TDB 240 mg b.d., furazolidone 100 mg b.d. and clarithromycin 250 mg b.d. (BFC group). H. pylori status was assessed by histology and culture of gastric biopsy specimens before and at least 4 weeks after completion of therapy. RESULTS: Seven patients (three in the BFJF group and four in the BFC group) dropped out. Eradication rates (intention-to-treat/per protocol) were 90%/95% in the BFJF group and 82%/88% in the BFC group, respectively (P > 0.05). Duodenal ulcer healing rates were 94% (16/17) in the BFJF group and 80% (20/25) in the BFC group, respectively (P > 0.05). Mild side-effects occurred in 11 (18%) patients in the BFJF group and 10 (17%) in the BFC group (P > 0.05). CONCLUSIONS: One-week quadruple therapy consisting of TDB, furazolidone, josamycin and famotidine achieves a high cure rate of H. pylori infection.

Role of Blepharis maderaspatensis and Ammannia baccifera plant extracts on in vitro oxygen radical scavenging, secretion of gastric fluid and gastroprotection on ulcer induced rats

Context: Blepharis maderaspatensis L. Roth (BM) (Acanthaceae) and Ammannia baccifera L. (AB) (Lythraceae) are used in folk medicine for various stomach disorders. Objective: The chloroform and ethanol extracts of both plants were evaluated for antioxidant, gastric antisecretory, and gastroprotective properties. Methods: Antioxidant properties of the extracts were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and nitric oxide (NO) scavenging assay. The gastric antisecretory properties of the extracts were assessed, at a dose of 100 and 200 mg/kg, using aspirin-pylorus ligation induced gastric ulcer models and the gastroprotective activity of the extracts was assessed, at a dose of 100 and 200 mg/kg, using HCl-ethanol induced ulcer models in rats. Results and discussion: Ethanol extract of BM (EBM) possessed good antioxidant property with IC(50) values of 37.4 and 44.1 μg/mL in DPPH and NO scavenging assays respectively, where 25-250 μg/mL concentration in DPPH assay and 30-300 μg/mL concentration in NO scavenging assay were used. Ethanol extract of AB (EAB) at a dose of 200 mg/kg reduced the free acidity to 142.66 mEq/L and total acidity to 451.22 mEq/l. It reduced the gastric secretion with increase in pH from 2.2 to 3.15. Possessing good antisecretory activity, it also reduced the ulcer by 92.2% in aspirin and pylorus ligation induced gastric ulcer models. EAB increased the mucus secretion and adherent mucus in the tissues with a 71.43% reduction of ulcerin HCl-ethanol induced ulcer models, at a dose of 200 mg/kg. This activity can be attributed to the various flavonoids like rutin and kaempferol-3-O-β-glucopyranoside, and the phytosterol, β-sitosterol-3-O-β-glucopyranoside, and phenolics present in the extracts. Conclusion: EBM possessed significant antioxidant property while EAB possessed good antisecretory and gastroprotective activity.     

Omeprazole, clarithromycin and furazolidone for the eradication of Helicobacter pylori in patients with duodenal ulcer

AIM: To evaluate the efficacy of omeprazole plus clarithromycin and furazolidone in Helicobacter pylori eradication and duodenal ulcer healing in Brazilian patients. METHODS: Forty H. pylori-positive patients with duodenal ulcer were randomized to receive 20 mg omeprazole o.m. or b.d. for 1 month plus 500 mg clarithromycin (b.d. ) and 200 mg furazolidone (b.d.) for 1 week. RESULTS: Three months after the end of the treatment the eradication rates were 90% by intention-to-treat analysis, and 97% by per protocol analysis. Mild side-effects were observed in 25 patients, none of whom abandoned the protocol. No difference was observed between the 20 mg and 40 mg omeprazole daily doses. Cure or significant improvement of the symptoms and of the histological alterations were observed after H. pylori eradication. CONCLUSION: Our results demonstrate that clarithromycin and furazolidone in combination with omeprazole are a good alternative for H. pylori eradication in Brazilian patients with duodenal ulcer.
