The present study was conducted to evaluate the antiulcerogenic effect and recognize the basic mechanism of action ofTabernaemontana divaricata(L.) R. Br. flowers.T. divaricataflower methanolic extract (TDFME) was screened for antiulcer activity versus aspirin and ethanol induced gastric ulcers at three doses—125, 250, and 500 mg/kg—orally using misoprostol as a standard. Besides histopathological examination, seven parameters, that is, ulcer index, total protein, nonprotein sulphhydryls, mucin, catalase, malondialdehyde, and superoxide dismutase levels, were estimated. In addition to HPLC profiling, GC-MS analysis and electrospray ionization—high resolution mass spectral (ESI-HRMS) analysis of crude TDFME were carried out in an attempt to identify known phytochemicals present in the extract on the basis ofm/zvalue. The results revealed a significant increase in the levels of catalase, superoxide dismutase, mucin, and nonprotein sulphhydryls, while they revealed a reduction in ulcer index, the levels of total protein, and malondialdehyde. Histopathological observations also demonstrated the protective effect. Though all the doses of TDFME exhibited gastroprotective function, higher doses were found to be more effective. Mass spectral analysis gave a few characteristicm/zvalues suggesting the presence of a few known indole alkaloids, while HPLC profiling highlighted the complexity of the extract. TDFME was found to exhibit its gastroprotective effect through antioxidant mechanism and by enhancing the production of gastric mucous.

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.

Ziziphus oxyphylla Edgew (ZO) has been traditionally used for the treatment of hepatic diseases in Pakistan. The current study was carried out to investigate the effectiveness and mechanism underlying hepatoprotective effect of ZO. Hepatoprotective potential of root extracts (crude methanolic extract and subsequent fractions) was investigated against carbon tetrachloride (CCl4) induced hepatotoxicity in BALB/c mice via determination of serum biomarkers, antioxidant enzymes (catalase, superoxide dismutase), lipid peroxidation and histopathology. Membrane stabilizing activity was determined via inhibition of hypotonic solution and heat-induced hemolysis. Crude methanolic extract and chloroform fraction ameliorated CCl4 induced elevated levels of alanine transaminase (ALT), alkaline phosphatase (ALP), total proteins (TP), total bilirubin (TB) and reversed the antioxidants imbalance in terms of catalase (CAT), superoxide dismutase (SOD) and reduced malondialdehyde (MDA) level. Crude methanol extract inhibited hemolysis induced by hypotonic solution and heat. Histopathological examination of liver specimens of extracts administered mice exhibited recovery from CCl4 induced pathological changes. Moreover, CCl4 induced alteration in body and liver weight was countered by the administration of ZO. Compounds betulinic acid (AZO1), ceanothic acid (AZO2) and zizybrenalic acid (AZO3) were isolated from chloroform fraction of the plant. The structures of compounds were deduced using 1D-and 2D-NMR spectroscopy techniques. The results show that Ziziphus oxyphylla roots extract possess antihepatotoxic activity mediated by the protection of anti-oxidant defense system and membrane-stabilizing activity, probably due to the presence of pentacyclic triterpenes

Channa striata (Bloch.) is a fresh water fish belonging to the family Channidae. The stripped snakehead fish possesses wide range of medicinal properties. In view of traditional use of C. striata for wound healing, the present study was undertaken to investigate the beneficial effects of orally administered freeze dried aqueous extract of Channa striata (AECS) in experimentally induced gastric ulcers in Wistar rats. Aspirin induced ulcerogenesis in pyloric ligation model was used for the assessment of antiulcer activity and Ranitidine (50 mg/kg) was employed as the standard drug. The various gastric parameters like volume of gastric juice, pH, free and total acidities, ulcer index, and levels of antioxidant enzymes like catalase, superoxide dismutase, and lipid peroxidation marker malondialdehyde were determined. AECS at concentrations of 40% and 50% w/v significantly decreased the volume of gastric juice and increased the levels of catalase while considerable decrease in free and total acidities and increase in superoxide dismutase were observed with the treatment of standard drug and AECS (50% w/v). All the test doses of AECS markedly decreased ulcer index and malondialdehyde compared to the standard drug whereas AECS 30% w/v did not alter volume of gastric juice, pH, free and total acidities, catalase, and superoxide dismutase. From these findings, it can be concluded that AECS is devoid of acid neutralizing effects at lower doses and possesses antisecretory and antiulcer activities and this could be related to its antioxidant mechanism.

Peptic ulcer is a condition which results from an imbalance between offensive and defensive factors of gastrointestinal system. The investigation was designed to evaluate the antiulcer activity of Symplocos racemosa whole plant methanol extract (MESR) in rat model of indomethacininduced gastric ulceration. The total acidity, gastric volume, pH and free acidity were measured to determine the anti-ulcer activity of MESR. Pretreatment with MESR (125-500 mg/kg) markedly reduced the indomethacin-induced increase in gastric ulcer index and score. These results revealed that antisecretory effects MESR were responsible for antiulcer activity of MESR.

AbstractTurmeric (Turmeric and ginger were evaluated for their antiulcer activity against ethanol-induced ulcers in male Wistar rats at different doses: 100, 500 and 1000 mg/kg body weight. Ethanol was used to induce gastric ulcer in Wistar rats. Parameters such as ulcer index, histopathology and levels of antioxidant enzymes such as glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase and glutathione (GSH) levels were measured to assess the degree of protection produced by the essential oils.TEO and GEO inhibited ulcer by 84.7% and 85.1%, respectively, as seen from the ulcer index. Reduced antioxidant enzymes such as GPx, SOD, catalase and GSH produced by alcohol administration were significantly (p<0.001) increased by simultaneous administration of TEO and GEO. Histopathological examination showed that ethanol-induced lesions such as necrosis, erosion and hemorrhage of the stomach wall were significantly reduced after oral administration of essential oils.Results suggest that TEO and GEO could reduce the gastric ulcer in rat stomach as seen from the ulcer index and histopathology of the stomach. Moreover, oxidative stress produced by ethanol was found to be significantly reduced by TEO and GEO.

The study was designed to investigate the antiulcer activity of ethyl acetate extract of the fruits of Morinda citrifolia Linn (Rubiaceae) using different models of gastric and duodenal ulceration in rats. Gastric ulcers were induced by oral administration of ethanol, aspirin and by pyloric ligation and duodenal ulcers were induced by oral administration of cysteamine HCl. The extract was administered at a dose of 200 and 400 mg/kg orally 30 min prior to ulcer induction. Ranitidine (50 mg/kg) was used as a reference standard.  The antiulcer activity was accessed by determining and comparing the ulcer index in the test group with that of the standard drug treated group. Gastric volume, total acid and free acid were estimated in the pylorus-ligated rats. M.citrifolia (400mg/kg) showed maximum inhibition of gastric acid, free acid and total acid to 53.54%, 52.55% and 30.30%, respectively. The ulcer index in the M.citrifolia treated animals was found to be significantly less in all the models compared to standard drug treated cases. The antiulcer activity of M.citrifolia was, however, less than that of ranitidine. The results suggest that M.citrifolia possesses significant antiulcer property which could be due to cytoprotective action of the drug or strengthening of gastric and duodenal mucosa with the enhancement of mucosal defence. Keywords: Morinda citrifolia; Antiulcer.© 2009 JSR Publications.

The cause of ulceration in patients is mainly due to hyper secretion of gastric juice and also due to hyper secretion of pepsin. In traditional system of medicine a number of herbal preparations have been used for the treatment of peptic ulcers. There are various medicinal plants has been used for the treatment of gastrointestinal disorders. In view of this, in present study we have to evaluate the anti-ulcer activity of parathenium hysterophorus. Study was carried out, by using three methods i.e., alcohol, paracetamol and stress induced ulcers in rats pretreated with the doses of 250 mg/kg AQPH and ALPH, 20mg/kg Omeoprazole and 50 mg/kg Ranitidine. To evaluate the antiulcer activity of aqueous and alcoholic extracts of parathenium hysterophorus leaves (AQPH and ALPH) at 250 doses using different experimentally induced gastric ulcer models in rats. Gastric ulcers were induced in rats by 80% alcohol, paracetamol and forced immersion stress induced methods. In alcohol induced ulcer model, paracetamol induced ulcer model and stress induced model the ulcer index was determined. Where as in stress induced ulcers stress plays an important role in ulcerogenesis. In alcohol-induced ulcers, AQPH and ALPH were effective in reducing lesion index and increasing the gastric mucus content. It was also effective in decreasing ulcer index in paracetamol-induced ulcers. All the results obtained with parathenium hysterophorus were dose dependent. The results suggest that AQPH and ALPH possesses significant and dose dependent antiulcer activity. The antiulcer activity of AQPH and ALPH can be attributed to its cytoprotective and antisecretory action.
