Abstract
Traditional uses for the plant Medicago sativa (M. sativa) (Alfalfa) (Family: Fabaceae) include liver protection, antioxidant activity, and the treatment of bleeding and digestive issues. This study aims to assess the effect of ethanol extract of M. sativa (EEMS) on experimental-induced ulcers in diabetic rats. By pylorus ligation and ethanol administration, gastric ulcers were induced in diabetic rats. Five groups each consisting of six rats in each model were used. All other groups except Group I were made diabetic by giving rats alloxan (140 mg/kg i.p.). Vehicles were given to Group I (normal control) and Group II (diabetes control) rats. Group III (positive control) received ranitidine 50 mg/kg, and Group IV and V received EEMS at doses of 100 and 400 mg/kg, respectively. In the pylorus ligation and ethanol-induced stomach ulcer model of rats, the findings demonstrated that EEMS (100 mg/kg) showed a decreased ulcer index of 2.01 ± 0.41 and was found statistically significant against the diabetes control group (p < 0.001) as well as, an ulcer index of 0.68 ± 0.22 by EEMS (400 mg/kg) with a significant reduction in the ulcer index (p < 0.001). EEMS (100 and 400 mg/kg) reduce free acidity by 13.16 ± 0.65 mEq/L and 9.83 ± 0.30 mEq/L, respectively. EEMS also showed a protective impact on the liver and kidneys of diabetic rats. Antihyperglycemic action was also discovered in diabetic animals. The findings of the current investigation demonstrated that ethanolic extract of M. sativa possesses anti-ulcer activity in diabetic rats. Ethanolic extract of M. sativa may be a treatment option for stomach ulcers that also have diabetes.

Abstract
The goal of the current study was to investigate the antioxidant, anti-ulcer, and analgesic properties of a metal-curcumin complex (MCC) utilizing different mouse and rat models. The antioxidant component of the analysis was completed in vitro, whereas the other activities were completed in vivo. The 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical cation scavenging test, the ferric-reducing antioxidant power (FRAP) assay, and the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical scavenging assay were used to measure the antioxidant activity. MCC demonstrated potent radical scavenging abilities. In all three experiments, Trolox served as the reference substance. When curcumin's radical scavenging abilities were compared, it became clear that MCC was a superior radical scavenger. Using the ethanol-induced technique on Sprague-Dawley rats, the anti-ulcerogenic effect was assessed. It shows that at an oral dosage of 100 mg/kg body weight, MCC might provide gastroprotection (b.w.). Additionally, we have examined MCC's potential as an analgesic. Swiss albino mice were used to measure the analgesic activity of MCC using the hot plate technique. At an oral dosage of 50 mg/kg b.w., MCC displayed analgesic efficacy. As a result, MCC could be useful in the management of inflammatory diseases.

Abstract
PURPOSE Rebamipide (REB) a potent anti-ulcer agent, has not been exploited to its full potential, owing to it extremely poor solubility, leading to highly diminutive bioavailability (<10%). The purpose is to carry out its solid-state modification. METHOD Cocrystallisation was done with three GRAS coformers namely citric acid (CA), 3,4-dihydroxybenzoic acid (DHBA) and oxalic acid (OXA) employing the liquid-assisted grinding method. Cocrystal formation was based upon amide-carboxyl and amide-hydroxyl supramolecular synthons. Characterization of novel cocrystals i.e. RCA, RDHBA and ROXA was carried out by DSC, PXRD and additionally by FT-IR spectroscopy. Chemical structures have been determined utilizing the PXRD pattern by Material Studio®. Furthermore, cocrystals were subjected to solubility and intrinsic dissolution rate (IDR) evaluation. Also, pharmacodynamic and pharmacokinetic studies were performed and compared with pure rebamipide. RESULT The appearances of a single sharp melting endotherm in DSC, along with novel characteristic peaks in PXRD infer the existence of a new crystalline form. Shifting in characteristic vibrations in FT-IR spectroscopy supports the establishment of distinct hydrogen-bonded networks. Structural determination revealed that RCA crystallizes in 'Bb2b' space groups whereas RDHBA in 'P1' and ROXA crystallize out in the 'P-1' space group. All the cocrystals exhibited superior apparent solubility and almost 7-13 folds increase in IDR. Furthermore, 1.6-2.5 folds enhancement in relative bioavailability and remarkable amplification in anti-ulcer, anti-inflammatory and the antioxidant potential of these cocrystals were observed. CONCLUSION The study ascertains the advantages of cocrystallization, with RCA showing greatest potential and suggests a viable alternative approach for improved formulation of rebamipide.

Abstract
BACKGROUND/AIMS This study was conducted to investigate the inhibitory effect of irsogladine maleate (IM) on gastric ulcers induced by ethanol and hydrochloric acid (HCl). METHODS Mice were pretreated with IM for 1 hours before ulcer induction. Gastric ulcers were induced by oral administration of an ethanol/HCl mixture. To clarify the action mechanism of IM, the roles of 3'5'-cyclic adenosine monophosphate (cAMP), nitric oxide (NO), adenosine triphosphate-sensitive potassium (KATP) channels, prostaglandins and transient receptor potential cation channel subfamily V member 1 (TRPV1) were investigated, and lipid peroxidation in the stomach of IM-treated and -untreated animals was also measured. RESULTS IM significantly reduced the extent of ethanol/HCl mixture-induced gastric ulceration. It exhibited dose-related gastroprotection against the ethanol/ HCl-induced lesions, while pretreatment with glibenclamide but not N(ω)-nitro- L-arginine methyl ester, reversed this action. While pretreatment with the TRPV1 antagonist capsazepine failed to effectively block the gastroprotective effect of IM, the non-selective cyclooxygenase inhibitor indomethacin almost abolished it. IM also decreased the level of thiobarbituric acid reactive substances. CONCLUSION We concluded that IM exhibited significant gastroprotective effects in an ethanol/HCl-induced ulcer model, which appear to be mediated, at least in part, by NO, cAMP, endogenous prostaglandins, KATP channel opening, activation of TRPV1 channels, and antioxidant properties.

Abstract
OBJECTIVES This study was designed to investigate various gastrointestinal effects of Manilkara zapota (Sapodilla), exploring its anti-diarrheal, anti-secretary, anti-spasmodic, anti-ulcer and anti-motility potential. MATERIALS AND METHODS Antidiarrheal and anti-secretary activities were investigated using castor oil induced diarrhea and castor oil induced fluid accumulation. Isolated rabbit jejunum tissues (antispasmodic) were employed for in vitro experiments. Antiulcer, antimotility and molecular docking were performed using ethanol-HCl induced ulcer assay, charcoal meal transit time and Auto Doc Vina. RESULTS Mz.Cr exhibited protection against castor oil-induced diarrhea (P<0.05 vs. saline group) and dose-dependently inhibited intestinal fluid secretions (P<0.001 vs. castor oil group). Mz.Cr caused relaxation of spontaneous and K+ (80 Mm)-induced contractions with EC50 values of 0.11mg/ml (0.08-0.1, n=4) and 0.16 mg/ml (0.09-0.2, n=4) respectively (* P<0.05** P<0.01 *** P<0.001). It showed protective effect against gastric ulcers induced by ethanol-HCl (P<0.001 vs. saline group). Mz.Cr reduced distance travelled by charcoal meal (P<0.001 vs. saline group). Plant constituents: caffeoylquinic acid and methyl 4-O-galloylchlorogenate showed high binding affinities (E-value≥-6.5 Kcal/mol) against histaminergic H2 receptors, H+/K+ ATPase pump and voltage gated L-type calcium channels, while possesses moderate affinities (E-value≥8 Kcal/mol) against histaminergic H1, muscarinic M1, M3 and mu-opioid, whereas lower affinities (E-value≥9.5 Kcal/mol) vs. calmodulin, adrenergic α1, phosphodiesterase enzyme and dopaminergic D2 receptors. Lupeol-3-acetate and β-amyrin-3-(3'-dimethyl) butyrate observed weak affinities. CONCLUSION In present study, M. zapota is reported to exhibits anti-diarrheal, anti-secretory, anti-spasmodic, anti-motility, anti-ulcer effects and computational binding affinities against gastrointestinal targets.

Abstract
Background The purpose of this study was to compare the efficacy and safety of curcumin with those of diclofenac in the treatment of knee osteoarthritis (OA). Methods In this randomized, open-label, parallel, active controlled clinical study, 139 patients with knee OA were randomly assigned to receive either a curcumin 500-mg (BCM-95®) capsule three times daily or a diclofenac 50-mg tablet two times daily for 28 days. Patients underwent assessment at baseline and days 7, 14, and 28. The main outcome measure was severity of pain using visual analogue scale score at days 14 and 28. Knee Injury and Osteoarthritis Outcome Score (KOOS) (at days 14 and 28), anti-flatulent effect (at day 7), anti-ulcer effect, weight-lowering effect, and patient’s and physician’s global assessment of therapy at day 28 were included as secondary outcome measures. Safety after treatment was evaluated by recording adverse events and laboratory investigation. Results At days 14 and 28, patients receiving curcumin showed similar improvement in severity of pain and KOOS scale when compared with diclofenac, and the difference was not statistically significant. At day 7, the patients who received curcumin experienced a significantly greater reduction in the number of episodes of flatulence compared with diclofenac (P <0.01). At day 28, a weight-lowering effect (P <0.01) and anti-ulcer effect (P <0.01) of curcumin were observed. None of the patients required H2 blockers in the curcumin group, and 19 patients required H2 blockers in the diclofenac group (0% versus 28%, respectively; P <0.01). Adverse effects were significantly less in the curcumin group (13% versus 38% in the diclofenac group; P <0.01). Patient’s and physician’s global assessment of therapy was similar in the two treatment groups. Conclusion Curcumin has similar efficacy to diclofenac but demonstrated better tolerance among patients with knee OA. Curcumin can be an alternative treatment option in the patients with knee OA who are intolerant to the side effects of non-steroidal anti-inflammatory drugs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Physalis alkekengi L. var. franchetii (Solanaceae) has been widely used in Chinese folk medicine due to its wide distribution throughout the country, for the treatment of a wide range of diseases including heat and cold, sore throat, fever, fungal infection, inflammation, toothache, rheumatism, burn, analgesic, ulcer and urinary diseases. However, the effect of P. alkekengi var. franchetii on ulcer and Helicobacter pylori infection has not been reported to date. AIM OF THE STUDY This study was designed to investigate the anti-inflammatory, anti-ulcer, anti-Helicobacter pylori and analgesic properties of ethyl acetate fraction of the crude aqueous methanolic extract from the aerial parts of the plant P. alkekengi L. var. franchetii in rodents. MATERIALS AND METHODS Acute toxicity of the crude extract of P. alkekengi L. var. franchetii (PAF) was evaluated in rats. The petroleum ether fraction (PEF), butanol fraction (BF), ethyl acetate fraction (EAF) and aqueous fraction (AF) of crude aqueous methanolic extract from PAF were screened for anti-inflammatory and anti-ulcer potential at doses of 100, 250 and 500mg/kg (p.o.), using carrageenin-induced hind paw edema and ethanol-induced gastric lesions test in rats. In vitro anti-Helicobacter pylori activity of EAF was assayed subsequently. In addition, three doses of EAF were evaluated for analgesic activity using hot plate and writhing tests, respectively. Finally, we performed a phytochemical analysis of EAF. RESULTS Four fractions of crude extract from PAF significantly reduced the paw volume in carrageenin-induced hind paw edema model at different doses (100, 250 and 500mg/kg, p.o.). The fraction EAF at a dose of 500mg/kg exhibited the highest (75.92%) (0.150 ± 0.045***, ***p < 0.001) anti-inflammatory potential, which is similar to indomethacin (***P < 0.001)(0.120 ± 0.014***, 80.74% inhibition of inflammation) at 5mg/kg. Pretreatment with EAF (500mg/kg, p.o.) significantly reduced the intensity of gastric mucosal damage and showed higher gastroprotective activity (90.6%) when compared to the standard drug famotidine (84.6%). In addition, EAF fraction also showed a moderate (P < 0.05) anti-Helicobacter pylori activity with a minimal inhibition concentration (MIC) of 500μg/ml. Furthermore, pain sensation was effectively inhibited at 500mg/kg, p.o. of EAF as manifested by an increase (p < 0.001) of latency time in hot plate from 30 to 90min and a decrease (p < 0.001) in count of writhing induced by acetic acid. By HPLC, we determined some steroid, terpenoid and flavonoids (four compounds): kaempferol, quercetin, Blumenol A and physalindicanols A, which were isolated from the ethyl acetate fraction and identified using 1H NMR and 13C NMR spectra analysis. CONCLUSION This study demonstrated the anti-inflammatory, anti-ulcer, anti-Helicobacter pylori and analgesic properties of EAF of the crude extract from PAF thus justifying its traditional usage.

Abstract
Efforts were made to synthesize a series of substituted methoxybenzyl-sulfonyl-1H-benzo[d]imidazole derivatives (8a-l) and investigate their anti-ulcer therapeutics. Prior to evaluating antiulcer potentials of 8a-l, a preliminary binding assay against H+/K+-ATPase from goat gastric mucosa was carried out, since it plays an important role in the ulcer development. In order to get more insight into the binding mode of the compounds to H+/K+-ATPase, a molecular docking study was carried out and the best binding affinities were unveiled. Many of the substituted methoxybenzyl-sulfonyl-1H-benzo[d]imidazole derivatives (8a-l) were active for the proposed activity. The key finding was that, least inhibitory constant (ki) values of 8a-l were found between 0.02 and 1.8 μM in the molecular docking study. Almost the same range was reflected/correlated in the H+/K+-ATPase inhibition assay (IC50 0.14-1.29 μM). Remarkably, compounds 8a-l showed a relative activity percentage range of 72-92%. Efficient HRBC membrane stabilization activity of 8a-l ensured the non-harm/safety and the suitability/alternative towards anti-ulcer therapy.

Abstract
A series of six novel benzimidazole-pyrazole hybrid molecules was synthesized and characterized using elemental analysis (CHN) and spectroscopic methods (1HNMR, FT-IR). All the synthesized compounds were evaluated for their in vivo anti ulcerogenic activity using Albino rats (weighing 180-220 g). The interactions between the compounds and active site residues of H+/K+ ATPase were investigated by molecular docking studies using autodock vina 4.0. SCH28080 was used to validate the docking results. Also the drug likeliness of these compounds was predicted using Molinspiration server in light of Lipinski's rule of five. All the six synthesized compounds exhibited higher anti-ulcer activity as compared to omeprazole. These novel hybrid compounds showed comparable anti-ulcer potential of 72-83% at dose level of 500 µg/kg, whereas omeprazole showed 83% anti-ulcer activity at dose level of 30 mg/kg. The results clearly indicate that these novel benzimidazole-pyrazole hybrids can present a new class of potential anti ulcer agents and can serve as new anti-ulcer drugs after further investigation. Graphical abstract An overveiw of synthesis, in silico and in vivo antiulcer screening of benzimidazole pyrazole hybrids.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zingiber simaoense Y. Y. Qian belongs to the Zingiberaceae family. Its rhizome has been used in Thai folk medicine to relieve gastric disorders; however, scientific evidence of its pharmacological activities has not yet been revealed. AIM OF THE STUDY This study was designed to validate the gastroprotective activity and to identify possible mechanisms of gastroprotection of Z. simaoense rhizome ethanol extract (ZSE) in rats. MATERIALS AND METHODS The gastroprotective effect of ZSE was tested using models of gastric ulcers induced by acidified ethanol, indomethacin, and restraint water immersion stress. Models for determination of gastric wall mucus secretion and plasma malondialdehyde levels as well as pylorus ligation were used to explore the mechanisms of action. RESULTS After oral administration by intragastric gavage, ZSE 7.5, 15, and 30mg/kg or cimetidine 100mg/kg significantly inhibited the formation of gastric ulcer in all gastric ulcer models. The gastric wall mucus amount was significantly higher than that of the ulcer control group, plasma malondialdehyde levels were normalized, and gastric secretion was partly inhibited by pretreatment with ZSE. CONCLUSIONS This study demonstrates the gastroprotective activity of ZSE in rats. The mechanisms of action of ZSE may depend on its ability to maintain the integrity of gastric wall mucus through the protection of gastric mucus, and/or by increasing the gastric mucus synthesis and secretion through prostaglandin synthesis. Moreover, the antioxidant activity of ZSE may also contribute to its mechanism of gastroprotection.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Piper umbellatum L. (Piperaceae) is a shrub found in the Amazon, Savannah and Atlantic Forest region of Brazil. It is widely used in folk medicine in many countries primarily for the treatment of gastric disorders. The aim of this study was to evaluate the gastroprotective and anti-ulcer effects of hydroethanolic extract of P. umbellatum (HEPu) leaves in experimental rodents. In addition, the anti-Helicobacter pylori activity of the extract was assessed. MATERIALS AND METHODS The leaves of P. umbellatum were macerated in 75% (1:3w/v) hydroethanolic solution to obtain HEPu. The gastroprotective and ulcer healing activities of HEPu were evaluated using acidified ethanol (acute) and acetic acid (chronic) gastric ulcer models in rodents. The anti-H. pylori activity was evaluated by in vitro broth microdilution assay using H. pylori cagA+ and vacA+ strain. The probable mechanism of action of HEPu was evaluated by determining gastric secretory parameters, antioxidant enzyme (catalase), non-protein sulfhydryl (glutathione) and malondialdehyde levels in gastric tissue, including pro-inflammatory (IL-1β, TNF-a, IL -17, RANTES, IFN-γ and MIP-2) and anti-inflammatory (IL-10) cytokines. RESULTS HEPu demonstrated potent gastroprotection against acute ulcer induced by acidified ethanol and excellent healing effect of the chronic ulcer induced by acetic acid. The gastroprotective activity in acidified ethanol is partly attributed to the antioxidant mechanisms, while anti-secretory, anti-inflammatory and regeneration of the gastric mucosa are evoked as part of its antiulcer mechanism of action. The gastric ulcer healing of HEPu also involves restoration of the altered cytokines levels to near normal. However, it has no in vitro anti-H. pylori activity. CONCLUSION The results of this study showed that HEPu possesses preventive and curative effects in experimental models of gastric ulcers in animals. These effects are partially dependent on antioxidant, antisecretory, anti-inflammatory and mucosa regeneration. It is independent of anti-H. pylori activity, with substances probably responsible for the pharmacological activity being flavonoids, quercetin and rutin. These results support the popular use of P. umbellatum leaves in the treatment of peptic ulcers.

Abstract
BACKGROUND Melissa officinalis (MO) has potent antioxidant activity. Recent research has demonstrated the anti-ulcer properties of some medicinal plants through their antioxidant properties. OBJECTIVES The aim of this study was to evaluate the effects of methanolic extracts of MO on experimental gastric ulcers in rats. MATERIALS AND METHODS Male Wistar rats (200 - 250 g) were starved for 24 hours prior to the induction of gastric ulceration by either indomethacin (48 mg/kg/oral) or water immersion restraint (WIR) stress. Experimental rats received either ranitidine (25 mg/kg) or MO extract (150, 300 and 450mg/kg) orally 2 hours prior to WIR stress or indomethacin treatment, for the evaluation of their gastroprotective effects. The control group received the same volume of saline. Gastric lesions were scored according to the surface of lesions on the ulcer index. Superoxide dismutase (SOD) and glutathione peroxidase (GPX) were determined as measures of antioxidant defense, and malondialdehyde (MDA) was determined to measure tissue oxidation. RESULTS MO extract (150 and 300 mg/kg) significantly decreased the ulcer index in both the indomethacin (1.3 ± 0.09 and 1.5 ± 0.19, respectively) and WIR stress groups (1.5 ± 0.17 and 1.5 ± 0.22, respectively), as compared to the control rats (2.5 ± 0.28) (P < 0.01). MO extract (450 mg/kg) significantly reduced ulcer index readings in WIR stress rats (1.8 ± 0.31 vs. 2.4 ± 0.15 in the WIR group), however, MO extract at a dose of 450 mg/kg did not prevent indomethacin-induced gastric ulceration (2.4 ± 0.26). There was no significant difference in the ulcer index for MO extract- (150 and 300 mg/kg) and ranitidine-treated rats (P > 0.05). Also, MO extract (150 and 300 mg/kg) significantly reduced MDA serum levels (0.69 ± 0.6 µmol/L and 0.85 ± 0.24 µmol/L, respectively, vs. 4.5 ± 1.9 µmol/L in the saline group) and significantly increased antioxidants' SOD activities (296.3 ± 146.4 U/mL and 561.4 ± 120 U/mL, respectively, vs. 190.2 ± 63.8U/mL in the control group) and GPX levels (8273 ± 3049 U/mL and 14574 ± 5012 U/mL, respectively), compared to the control (3236 ± 1699 U/mL). CONCLUSIONS Our results showed that MO extract may have a gastroprotective effect against experimental gastric ulcers in rats. The exact mechanism has not yet been determined, but it may be due to enhancing enzymatic antioxidant defenses and inhibiting lipid peroxidation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Euphorbia umbellata (leitosinha) is used in southern Brazilian folk medicine to treat gastric problems, as well as for its analgesic and anti-inflammatory properties. AIM OF STUDY To evaluate the anti-ulcer effects of methanolic bark fraction (MF) against in vivo and in vitro assays, as well as an antioxidant, antibacterial and chromatographic study of this fraction. MATERIALS AND METHODS In vivo anti-ulcer activity was performed using ethanol and indomethacin models with different MF concentrations (50, 100 or 200mg/Kg). The stomachs of the animals were applied to histological evaluation, and the serum to evaluate the ABTS(•+) radical capture. The 200mg/Kg dose was used to analyze the mechanisms involved in antiulcerogenic properties of methanolic fraction. The in vitro activity was performed using several different antioxidant assays, in addition to anti-Helicobacter pylori and anti-urease experiments. The chromatographic study was carried out by LC-MS analysis. RESULTS Pharmacological investigation of the MF showed an anti-ulcer potential in ethanol and indomethacin in vivo assays. The material presented a high antioxidant activity for several oxidant in vitro systems (DPPH(•), ABTS(•+), O2(•-), HOCl, TauCl and HRP), as well as an ABTS(•+) capture increasing (7.5%) by the treated animals serum (when compared to the negative control). Prostaglandins, nitric oxide/ cyclic guanosine monophosphate pathway and involvement of the protein components of the glutathione complex are some of the mechanisms related with this potential anti-ulcer action. The histological examination of the stomachs of the animals showed that the MF also prevents local action of offensive agents. Chemical analysis using LC-QTOF-MS revealed the presence of ellagic and gallic acid derivatives and flavonols. CONCLUSION The findings provide scientific basis to the ethnopharmacological purpose of the studied plant and the biological activities of MF of E. umbellata stem bark may be due to the presence of phenolic compounds.

Abstract
The reaction of androstenedione with bromine gave the 16-bromo derivative 2. The latter reacted with either cyanothioacetamide or thiourea to give the 2-cyanomethylthiazole derivative 4 and the 2-aminothiazole derivative 13. Compound 4 and 13 were used underwent some condensation, coupling and heterocyclization reactions to give thiophene, pyridine and pyran derivatives. The anti-inflammatory and anti-ulcer evaluations of the newly synthesized products were evaluated and the results showed that 23f showed the maximum antiulcer activity. In addition, toxicity of the most active compounds was studied against shrimp larvae and showed that compounds 2, 23c and 23f showed non-toxicity against the tested organisms.

Abstract
Background: This study investigated the anti-ulcer and ulcer healing potentials of the methanol extract of Musa sapientum peel in the laboratory rats. Materials and Methods: Methanol extract of the peels on Musa sapientum (MEMS) was evaluated for its anti-ulcer using alcohol-induced, aspirin-induced, and pyloric ligation-induced models, and for its ulcer healing employing acetic acid-induced ulcer models in rats. Results: The findings from this experiment showed that MEMS (50, 100 and 200 mg/kg, b.w.) anti-ulcer and ulcer healing activity (P ≤ 0.05) is dose-dependent. Also, MEMS exhibited healing of the ulcer base in all the treated groups when compared with the control group. Conclusion: The outcomes of this experiment revealed that the anti-ulcer effect of MEMS may be due to its anti-secretory and cyto-protective activity. The healing of the ulcer base might not be unconnected with basic fibroblast growth factors responsible for epithelial regeneration.

Abstract
The present study is designed to explore the mechanism of action of herbal formulation Lucer against experimentally induced gastric ulcers. The aqueous extract (120 and 180 mg/kg) of Lucer was tested against aspirin and ethanol-induced gastric ulcer model in rats. The drug has been found to be very effective in inhibiting gastric ulceration. This is evident from reduction in ulcer index parameters. Besides, significant reduction in acid secretory parameters such as total acidity, total acid output and volume of gastric secretion were also observed. It is concluded from this study that the drug possesses anti-ulcer activity in both the models. The anti-ulcer activity of the drug can be attributed to inhibition of acid secretary parameters and strengthening of gastric mucosal barrier.

Abstract
BACKGROUND The present study was undertaken to evaluate the anti-ulcer and antioxidant activities of the ethanol extract of Lagenaria breviflora (EELB) whole fruit in laboratory rats. METHODS The anti-ulcer property of the ethanolic extract of the whole fruit of Lagenaria breviflora (LB) was assessed using the cold-restraint stress-induced (CRU) gastric ulcer, pyloric ligation-induced (PL) gastric ulcer, aspirin-induced (ASP) gastric ulcer and alcohol-induced (AL) gastric ulcer models. The scavenging activity of the LB extract was examined with 1, 1-diphenyl-2-picryl-hydrazyl (DPPH), Nitric oxide, Hydroxyl radical and Superoxide anion scavenging models. RESULTS EELB (50, 100, 150 and 200 mg/kg, b.w.) protected against the CRU gastric ulcer dose dependently. Similarly, 150 mg/kg b.w. of the LB extract protected against the PL gastric ulcer, ASP gastric ulcer and AL gastric ulcer and was comparable to omeprazole (10 mg/kg b.w.) or Suscralfate (500 mg/kg b.w.), respectively. The in vitro antioxidant activity of LB was demonstrated by its ability to quench free radicals generated by nitric oxide and superoxide anion with a concomitant scavenging potential against DPPH-induced radical formation. CONCLUSION Taken together, the study showed that the whole fruit extract possess potent anti-ulcer and antioxidant activities.

Abstract
BACKGROUND The roots of Zapoteca portricensis is a common remedy in the treatment gastrointestinal disorders used by tradomedical practitioners in Eastern Nigeria. AIM This study was aimed at evaluating the possible antiulcer activity of the root of this plant in experimental rats. METHODS A methanolic root extract was prepared by cold maceration. Antiulcer activity was tested using absolute ethanol and indomethacin induced ulcer models. Sucralfate (100 mg/kg oral) was used as the reference drug. Different groups of albino rats of male sex were given three doses (50, 100, 200 mg/kg) of the extract. Phytochemical analysis of the freshly dried roots was also done. RESULTS Phytochemical results revealed presence of alkaloids, terpenoids, glycosides and flavonoids. The ethanol model produced an average ulceration in rats with reduction of ulcer (50%, 75% and 90%) seen in all the extract treatment. A dose dependent inhibition of ulcer was seen in all doses of the extract with doses 100 and 200 mg/kg produced a significant reduction compared with control. In the indomethacin model, an absolute ulceration was produced in all the animals. Inhibition of ulcer (57.1%, 65.7% and 80.0%) was seen in the treatments with the extracts in a dose dependent manner. All the three doses of the extracts produced significant ulcer protection compared with control. CONCLUSION This study has shown that roots of this plant (Zapoteca portoricensis) possess potent antiulcer activity.
