Abstract
Background. The present study aimed to assess and compare the pain perception and ulcer sizes before and after applying low-level laser therapy (LLLT) and Amlexanox + lidocaine. Methods. Twenty-six patients referring to the out-patient department of the institution and diagnosed with recurrent aphthous ulcers (RAU) were assigned to two groups to receive either LLLT or Amlexanox + lidocaine. In group 1, the patients were provided with amlexanox + lidocaine to apply topically four times daily. In group 2, the patients underwent LLLT with no tissue contact in inward circular motions for two cycles for 30 seconds. This study was registered in "the Clinical Trials Registry- India" (CTRI), with the registration number CTRI/2019/09/028222. The data were analyzed with SPSS 16. Results. The intergroup comparison was performed using Mann-Whitney U test, and intragroup comparisons were made using Wilcoxon’s signed-rank test. The level of significance was set at P <0.05. The results showed that pain perception and ulcer size were significantly lower in group 2 subjects than group 1 subjects (P <0.05). Conclusion. LLLT was more effective than amlexanox + lidocaine in the management of RAU. It is a cost-effective therapy for treating RAU.

Abstract
Peptic Ulcer Disease (PUD) is the most common disorder of the stomach and duodenum, which is associated with Helicobacter pylori infection. PUD occurs due to an imbalance between offensive and defensive factors and Proton Pump Inhibitors (PPI), Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) and antibiotics are frequently used for the treatment. Recently, medicinal plants have emerged as efficacious, safe and widely available alternative therapies for PUD. The aim of this review was to study the medicinal plants and phytochemicals, which have been used for PUD treatment to evaluate the potential role of natural compounds to develop herbal remedies for PUD. Information was obtained using a literature search of electronic databases, such as Web of Science, Google Scholar, PubMed, Sci Finder, Reaxys and Cochrane. Common and scientific names of the plants and keywords such as 'peptic ulcer', 'gastric ulcer', 'stomach ulcer' and 'duodenal ulcer' were used for search. Eventually, 279 plants from 89 families were identified and information on the plant families, part of the plant used, chemical constituents, extracts, ulcer model used and dosage were abstracted. The results indicated that most of the anti-PUD plants were from Asteraceae (7.1%) and Fabaceae (6.8%) families while flavonoids (49%), tannins (13%), saponins (10%) and alkaloids (9%) were the most common natural compounds in plants with anti-PUD activity.

Abstract
Cenostigma macrophyllum Tul. var. acuminata Teles Freire (Leguminosae-Caesalpinioideae) is a medicinal plant traditionally used for treatment of gastric ulcer. This study evaluated the ulcer-healing activity of the hydroalcoholic fraction of C. macrophyllum Tul. var. acuminata Teles Freire leaves (Cm-FHA) and the tea of the leaves of C. macrophyllum (Cm-tea), as well as the possible action of Cm-FHA, through in vitro models. Leaves of C. macrophyllum were dried and powdered to obtain the Cm-FHA. Subsequently, the Cm-FHA was characterized phytochemically and biologically. Besides, Cm-tea was prepared. The gastric healing effects of Cm-tea and Cm-FHA were analyzed using the model of acetic acid-induced gastric ulcer in rats. The human gastric adenocarcinoma (AGS) cell line was employed as an in vitro model. Cm-tea promoted a protective effect against gastric ulcers induced by absolute ethanol. Cm-FHA or Cm-tea (100 mg/kg/7 days) exhibited a significant healing effect on ulcers induced by acetic acid. In the histological analysis, gastric mucosa treated with Cm-FHA or Cm-tea advanced restoration of the mucosal epithelium. In vitro, lower concentrations of Cm-FHA stimulated cell proliferation in the BrdU assay and cell migration. Cm-tea and Cm-FHA present a significant gastric healing effect in in vivo and in vitro models.

Decyl Gallate as a Possible Inhibitor of N-Glycosylation Process in Paracoccidioides lutzii. Antimicrob Agents Chemother 2019; 63:AAC.01909-18. [PMID: 31451502 DOI: 10.1128/aac.01909-18] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Accepted: 07/28/2019] [Indexed: 01/29/2023] Open
Abstract
The available antifungal therapeutic arsenal is limited. The search for alternative drugs with fewer side effects and new targets remains a major challenge. Decyl gallate (G14) is a derivative of gallic acid with a range of biological activities and broad-spectrum antifungal activity. Previously, our group demonstrated the promising anti-Paracoccidioides activity of G14. In this work, to evaluate the antifungal characteristics of G14 for Paracoccidioides lutzii, a chemical-genetic interaction analysis was conducted on a Saccharomyces cerevisiae model. N-glycosylation and/or the unfolded protein response pathway was identified as a high-confidence process for drug target prediction. The overactivation of unfolded protein response (UPR) signaling was confirmed using this model with IRE1/ATF6/PERK genes tagged with green fluorescent protein (GFP). In P. lutzii, this prediction was confirmed by the low activity of glycosylated enzymes [α-(1,3)-glucanase, N-acetyl-β-d-glucosaminidase (NAGase), and α-(1,4)-amylase], by hyperexpression of genes involved with the UPR and glycosylated enzymes, and by the reduction in the amounts of glycosylated proteins and chitin. All of these components are involved in fungal cell wall integrity and are dependent on the N-glycosylation process. This loss of integrity was confirmed by the reduction in mitochondrial activity, impaired budding, enhancement of wall permeability, and a decrease in viability. These events led to a reduction of the ability of fungi to adhere on human lung epithelial cells (A549) in vitro Therefore, G14 may have an important role in balancing the inflammatory reaction caused by fungal infection, without interfering with the microbicidal activity of nitric oxide. This work provides new information on the activity of G14, a potential anti-Paracoccidioides compound.

Abstract
Doxycycline (DOX) and amoxicillin (AMOX) are important Broad-spectrum antibiotics used in treating multiple human and animal diseases. For the sake of exploring novel medical applications, both antibiotics were loaded into magnesium aluminium layer double hydroxide (Mg-Al)/LDH nanocomposite through the co-precipitation method. The synthesized materials were characterized by XRD, FT-IR, particle size analysis, FESEM and HRTEM. Acute toxicological studies were conducted using median lethal dose LD50, where a total number of 98 rats (200-150 gm) of both sexes were used. An experimental wound was aseptically incised on the anterior-dorsal side of each rat, while 98% of pure medical ethanol was used for ulcer induction. Acute toxicity, wound closure rate, healing percentages, ulcer index, protective rate and histopathological studies were investigated. Antibiotic Nanocomposites has significantly prevented ulcer formation and improved wound healing process to take shorter time than that of the typical processes, when compared with that of same drugs in microscale systems or commercial standard drugs. These results were confirmed by the histopathological findings. By converting it into the Nanoform, which is extremely important, especially with commonly used antibiotics, novel pharmacological properties were acquired from the antibiotics. The safe uses of DOX/LDH and AMOX/LDH Nanocomposites in this study were approved for biomedical applications.

Anti-inflammatory action of an alkaloid, fraction and extract from Alchornea glandulosa in mice. JOURNAL OF ETHNOPHARMACOLOGY 2019; 231:66-72. [PMID: 30395975 DOI: 10.1016/j.jep.2018.11.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2018] [Revised: 10/12/2018] [Accepted: 11/01/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alchornea glandulosa (Euphorbiaceae) has traditionally been used in medicine for treating immune-mediated inflammatory diseases. AIM OF STUDY This work aimed to evaluate the anti-inflammatory effects of a methanolic extract of leaves from A. glandulosa (MEAG), as well as the ethyl acetate fraction (EAFAG) and isolated compound guanidine alkaloid N-1, N-2, N-3-triisopentenylguanidine (AG-1), in experimental in vivo models of inflammation in mice. We also investigated this extract's phenols, flavonoids and flavonol compounds. MATERIALS AND METHODS MEAG (extracted by maceration with methanol), EAFAG (fraction resulting from the partition of the methanolic extract with ethyl acetate) and AG-1 (alkaloid isolated by chromatographic methods) were analysed. MEAG and EAFAG were analysed by HPLC/DAD. The effects of MEAG (30, 100 and 300 mg/kg), EAFAG (30, 100 and 300 mg/kg) and AG-1 (5 and 30 mg/kg) were studied in the following experimental mouse models: paw oedema and myeloperoxidase (MPO) activity, croton-oil-induced ear oedema, leukocyte migration in a pleurisy model induced by carrageenan and zymosan induction of joint inflammation. RESULTS MEAG and EAFAG were analysed by LC/DAD, and phenolic acids (gallic acid and caffeic acid) and flavonoids (myricetin-3-O-α-rhamnopyranoside and quercetin) were detected. MEAG, EAFAG and AG-1 were used in the carrageenan-induced paw oedema model and showed maximum inhibitions of 60.10% (MEAG, 2 h, 300 mg/kg) and 66.21% (EAFAG, 2 h, 300 mg/kg). AG-1 at 5 mg/kg showed significant inhibition, ranging from 60.92% to 63.13%, at all evaluated times, and the 30 mg/kg dose showed inhibition of 42.12% (1 h) and 40.36% (2 h). MEAG (37%, 46.1% and 68.11%) and EAFAG (31%, 42.21% and 48.93%), at doses of 30, 100 and 300 mg/kg, respectively, significantly reduced the increase in MPO activity, and AG-1 (5 and 30 mg/kg) showed inhibition of 64.62% and 65.12%, respectively. In the pleurisy model, MEAG (300 mg/kg), EAFAG (300 mg/kg) and AG-1 (30 mg/kg) significantly reduced the migration of total leukocytes with maximal inhibition of 80.90%, 83.17% and 89.39%, respectively. In the croton oil model, pretreatment with MEAG (0.1, 0.3 and 1 mg/ear) increased the diameter of the right ear (30.32%, 48.87% and 53.09%, respectively). Finally, MEAG (100 and 300 mg/kg; 33.11% and 56.03%) and EAFAG (100 and 300 mg/kg; 36.89% and 50.53%) reduced zymosan-induced oedema formation. CONCLUSIONS To the best of our knowledge, these results are the first to demonstrate that A. glandulosa exhibits oral and topical anti-inflammatory activity. This study detected alkaloid and phenol/polyphenolic compounds in A. glandulosa, which may help to explain the ethnobotanical use of this plant in traditional medicine in Brazil to treat immune-mediated inflammatory diseases.

Abstract
Some plants popularly employed for the treatment of peptic ulcers have proved to be attractive sources of new drugs. Despite extensive research, the pharmacological and toxicological potentials of these plants are not fully understood. In this context, the aim of this work was to analyze the multielemental composition of the methanolic extracts of three of those plants, Alchornea glandulosa (AG), Davilla elliptica (DE) and Davilla nitida (DN), with the intention of contributing to the understanding of the mechanisms of action of these extracts. For this purpose, we used the analytical technique of total reflection X-ray fluorescence (TXRF) by synchrotron radiation at the Brazilian Synchrotron Light Source (LNLS/CNPEM). It was possible to determine the concentrations of the elements: P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb and Br in all of the samples. Selenium (Se) was detected only in the DN extract. An inverse relationship between the concentrations of elements with proven effectiveness and the gastroprotective activity of extracts considering induction protocols with ethanol and non-steroidal anti-inflammatory drugs (NSAIDs) was obtained. This data suggests that the function of the extract is not only associated with providing the elements for restoring the gastric mucosa but that it also promotes the displacement of these elements from other parts of the mucosa to the damaged area. Correlations between the concentrations of the elements were also obtained. In the DE extract, which is the most effective extract for both induction protocols, the obtained correlations were above 70% among almost all of the elements, and no anticorrelations were found. For the other two extracts, in the less effective extract (AG) anticorrelations above 70% were predominantly found. Meanwhile, in the DN extract, a few high anticorrelations were found, which may explain its intermediate stage of effectiveness.

Abstract
Plant extracts exist as a complex matrix which serves as a source of numerous bioactive metabolites. The ultra performance liquid chromatography with diode-array detection-coupled electrospray ionization-mass spectrometry/mass spectrometry technique was used to characterize the aqueous extract from leaves of Alchornea glandulosa (EAG), a species popularly used to treat gastrointestinal problems as an antiulcer agent. Quantification of phenolic derivatives was determined using Folin-Ciocalteu and aluminum trichloride (AlCl3) methods. In addition, antioxidant (2,2-diphenyl-1-picrylhydrazyl [DPPH•] radical scavenging, β-carotene-linoleic acid, and lipid peroxidation), antibacterial (agar well diffusion method and minimum inhibitory concentration), antimutagenic (Ames test), and antigenotoxic (plasmid cleavage) assays were also performed on this plant extract. The ellagitannin tris-galloyl-hexahydroxydiphenic acid-glucose was identified as the predominant compound along with tannins as majority metabolites. EAG showed high antioxidant activity accompanied by moderate antibacterial activity against Staphylococcus aureus. The highest antimutagenic activity was observed for TA97 strain without metabolic activation (S9) and with metabolic activation, TA100 and TA102 were completely inhibited. In addition, EAG exhibited potential signs of antigenotoxic action. The high antioxidant and antimutagenic activity observed for EAG suggests important therapeutic uses that still need to be verified in future studies.

Abstract
Background Herbal medicines are now recently used as treatment options. This study was conducted to determine the effect of the combination therapy of medicinal herbs in the treatment of induced gastrointestinal injury among albino wistar rats. Methods A total of 60 Albino Wistar rats of both sexes weighing between 130g-150g were used. The control groups which consisted of negative control groups received 1ml of normal saline while the positive control group was given 20mg/kg of indomethacin and sacrificed after 6 hours. Those in the test group were given 20mg/kg of indomethacin, treated in different doses of single and combined extracts of Allium sativum, Brassica oleracea and Aloe barbadensis at 100mg/kg, 200mg/kg and 300mg/kg body weights, twice daily for 8 days and sacrificed. Results There was no visible sign of ulceration or perforation observed on the stomach and duodenum when compared with the control. The combination of all three plant extracts at different concentrations ranging from 100 – 300mg/kg cleared all visible ulcers and perforations on the stomach of wistar rats. Similarly, all ulcers in the duodenum of indomethacin induced wistar rats were cleared by the combination of the three extracts. The sections of rat stomach and duodenum given 100mg/kg herbal cocktail and indomethacin showed normal mucosa. Conclusions A mixture of the three herbs at 300mg/kg was better in healing gastric and duodenal ulcers. The mixture of the three plants extracts exhibit good anti-ulcer activity that warrants further studies.

Abstract
Ximenia americana L. (Olacaceae) is used in ethnomedicine as cicatrizant and for the treatment of gastric disorders. This study identified the chemical constituents of the aqueous extract of X. americana (XaAE) and evaluated its antiulcerogenic activity. After lyophilization, XaAE was analyzed by liquid chromatography-mass spectrometry (LC-MS) and its antiulcerogenic effect was evaluated in acute gastric lesions induced by ethanol, acidified ethanol, and indomethacin. Antisecretory action, mucus production and the participation of sulfhydryl groups (-SH) and nitric oxide (NO) were also investigated. The chromatographic analysis identified procyanidins B and C and catechin/epicatechin as major compounds. Oral administration of XaAE (100, 200 and 400 mg/kg) inhibited the gastric lesions induced by ethanol (76.1%, 77.5% and 100%, respectively), acidified ethanol (44.9%, 80.6% and 94.9%, respectively) and indomethacin (56.4%, 52.7% and 64.9%, respectively). XaAE reduced gastric contents and acidity (51.4% and 67.7%, respectively) but did not alter the production of gastric mucus. The reduction of the -SH and NO groups promoted by N-ethylmaleimide (NEM) and Nω-nitro-l-arginine-methyl-ester (L-NAME) respectively, reduced the gastroprotective effect of XaAE. In conclusion, XaAE has gastroprotective activity mediated in part by -SH, NO and antisecretory activity. This antiulcer action was initially correlated to its major constituents, procyanidins B and C and catechin/epicatechin.

Abstract
Methyl gallate is a gallotannin widely distributed in nature. Previous studies have demonstrated its antioxidant, anti-inflammatory, antimicrobial and anti-tumor activities. In the present study, the activity of methyl gallate on experimental models of inflammatory bowel disease has been investigated. Experimental colitis was induced in Sprague-Dawley rats through the intracolonic instillation of an acetic acid solution (2 mL, 4% v/v). Methyl gallate (100 and 300 mg/kg, p.o.) and the reference drug mesalazine (100 mg/kg, p.o.) were tested. Methyl gallate induced a significant reduction in the colon weight/length ratio and macroscopic lesion score. Besides, the malondialdehyde content and the GSSG/GSH ratio were remarkably decreased. Furthermore, the administration of methyl gallate reduced the expression of COX2, IL-6, TNFα and the severity of microscopic tissue damage induced by acetic acid, while the mean goblet cell density was significantly higher in both the group treated with methyl gallate and the one treated with mesalazine, in comparison with untreated animals. The Na+K+ATPase pump activity was recovered in treated groups (control: 827.2 ± 59.6, colitis: 311.6 ± 54.8, methyl gallate 100 mg/kg: 642.2 ± 175.0, methyl gallate 300 mg/kg: 809.7 ± 100.6, mesalazine: 525.3 ± 81.7). Methyl gallate was also found to induce a significant reduction in the castor oil-induced intestinal motility in Swiss mice, decreasing the peristalsis by 74.5 and 58.82% at 100 and 300 mg/kg p.o., respectively. This compound also antagonized the jejunum contractions induced by Ach and CaCl2. This study demonstrates that methyl gallate exerts beneficial effects in a preclinical model of intestinal disorders.

Abstract
Background Recurrent Aphthous stomatitis (RAS) is a prevalent ulcerative and painful disorder of the oral cavity with unknown etiology and for which no efficient treatment is currently available. The present study aimed to evaluate the safety and the efficacy of AphtoFix®, a new mouth ulcer cream that was developed to help treat RAS. Prior to launching the product on the market, two initial safety assessment studies were performed. Subjects and methods In a first study, the in vitro biocompatibility of AphtoFix® was evaluated on reconstructed human gingival tissue models according to ISO guidelines 10993. In a second study, the tolerability of AphtoFix® was evaluated in 20 subjects during a 4-weeks daily application in the mouth. The third study investigated both the safety and efficacy of AphtoFix® treatment on 19 patients suffering from RAS. This study was done in compliance with the Helsinki Declaration. Results The results of in vitro biocompatibility study showed that AphtoFix® mouth ulcer cream did not induce any detectable cytotoxicity and irritation. These observations were confirmed in the 4 weeks tolerability study where no undesired of adverse reactions were noticed. The results of the post-market clinical efficacy study demonstrated a clear reduction in ulcer size from baseline after 3 days treatment (p < 0.05). Pain intensity reduction was also observed in all subjects. Conclusion The application of AphtoFix® did not induce any undesired skin or mucosa reactions. These initial findings demonstrate that AphtoFix® is safe and efficient in reducing ulcer size and decreasing the pain intensity induced by ulcers.

Abstract
Peptic ulcers are open sores or erosions in the lining of either the duodenum (duodenal ulcers) or the stomach (gastric ulcers). Peptic ulcer, which is mainly caused by bacterial attack or excess of acid secretion, can be cured effectively by these isolated plant compounds. In this present scenario, demand for herbal medicines are increasing due to easy availability in surrounding place at low cost. This review article is all about such isolated plant compounds such as alkaloids, flavonoids and terpenoids. Various plants have been used as folk medicine by the people of rural area, which shows significant effect against peptic ulcer. Further study should be conducted upon these herbal plants because there is possibility for minimising the adverse effect caused by the present antiulcer drugs.

Abstract
Gastric ulcer is a common disorder of the digestive system. Current therapeutic regimens largely rely on Western medicine. However, numerous studies have demonstrated that herbal medicines can effectively treat gastric ulcer in humans and various animal models via divergent mechanisms. This review updates the efficacy and safety of herbal medicines in treating gastric ulcer, and the mechanisms of their action in humans and animal models. Studies have demonstrated that the efficacy of herbal medicines is comparable or superior to that of drugs such as omeprazole or cimetidine in humans and animal models, and herbal medicines display fewer adverse effects. The mechanisms by which herbal medicines benefit gastric ulcer include stimulation of mucous cell proliferation, anti-oxidation, and inhibition of gastric acid secretion and H(+)/K(+)-ATPase activity. Some herbal medicines also exhibit antimicrobial properties. Utilization of herbal medicines could be a valuable alternative to treat gastric ulcer in humans effectively, with few adverse effects.

Abstract
CONTEXT Potentilla mooniana Wight. (Rosaceae) is a plant found in the Himalayan region where the root is traditionally used to treat stomach problems including gastric-ulcer. OBJECTIVE To scientifically validate the gastro-protective effect and derive the possible mechanistic activity of the ethanol root extract from P. mooniana (EPM). MATERIALS AND METHODS The gastroprotective effect of EPM (100-400 mg/kg, p.o.) was evaluated on both the physical (Pyloric ligation, PL; Cold restrain stress, CRS) and chemical (absolute ethanol, EtOH; aspirin, ASP) ulcerogens induced ulceration in rats. The mechanistic activity of EPM was tested on various gastric-ulcer parameters, namely gastric pH, volume, acid-pepsin output, DNA content, histamine level, H(+)K(+)-ATPase activity, mucus content, microvascular permeability, antioxidant markers, and gastric-histopathological study. RESULTS EPM significantly reduces the ulcer score against all the four tested gastric-ulcer models. In the PL model, EPM showed significant reduction (p < 0.05) in acid-pepsin output and cell shedding; however, no significant effect was observed on gastric volume, cell proliferation, stomach glandular weight, and histamine levels. EPM (400 mg/kg, p.o.) when compared with ulcer control showed significant increase in gastric pH by 41.6% and decrease in H(+)K(+)-ATPase activity by 47.73%. In addition, EPM showed significant increase in mucus content by 58.60% and a decrease in the microvascular permeability of Evans Blue by 85.00%, justifying its protective effects. Furthermore, EPM also showed significant antioxidant activity and histopathologically possessed excellent cytoprotective effect. CONCLUSION The gastro-protective effect of EPM is attributed mainly to the defensive mechanism owing to the presence of a good quantity of polyphenolic components.

Abstract
Peptic ulcer disease continues to be issue especially due to its high prevalence in the developing world. Helicobacter pylori (H. pylori) infection associated duodenal ulcers should undergo eradication therapy. There are many regimens offered for H. pylori eradication which include triple, quadruple, or sequential therapy regimens. The central aim of this systematic review is to evaluate the evidence for H. pylori therapy from a meta-analytical outlook. The consequence of the dose, type of proton-pump inhibitor, and the length of the treatment will be debated. The most important risk factor for eradication failure is resistance to clarithromycin and metronidazole.

Abstract
Ten Brazilian medicinal plants used to treat gastritis and ulcers were carefully selected on the basis of ethnopharmacological importance and antiulcerogenic activity previously described. The antioxidant activity of the methanolic extracts was determined in analysis conditions that simulate a real biological activity on inhibition of the oxidative burst induced in neutrophils using Helicobacter pylori as activator, by a luminol-amplified chemiluminescence assay. The extracts, at low concentration (5 μg/mL), exhibited a large variation in inhibitory effects of H. pylori-induced oxidative burst ranging from 48% inhibition to inactive, but all extracts, excluding Byrsonima intermedia, had inhibitory activity over 80% at the concentration of 100 μg/mL. The total suppressive antioxidant capacity measured as the effective concentration, which represents the extract concentration producing 50% inhibition of the chemiluminescence induced by H. pylori, varies from 27.2 to 56.8 μg/mL and was in the following order: Qualea parviflora > Qualea multiflora > Alchornea triplinervia > Qualea grandiflora > Anacardium humile > Davilla elliptica > Mouriri pusa > Byrsonima basiloba > Alchornea glandulosa > Byrsonima intermedia. The main groups of compounds in tested extracts are presented. Differences in the phytochemical profile, quantitatively and qualitatively, of these plants can explain and justify their protective effect on the gastric mucosa caused by the neutrophil-generated ROS that occurs when H. pylori displays its evasion mechanisms.

Abstract
Combretum duarteanum Cambess. is found in South America, particularly in Bolivia, Paraguay, and Brazil. In Paraiba state (Brazil), the species usually occurs in the Caatinga biome. It is popularly known as mofumbo, cipiúba, or cipaúba. This work aims to evaluate the gastroprotective activity and the cytoprotective mechanisms of the ethanolic extract (Cd-EtOHE) and hexane phase (Cd-HexP) obtained from the leaves of C. duarteanum. Doses at 62.5, 125, 250, and 500 mg/kg of Cd-EtOHE and Cd-HexP were tested in models of gastric ulcers induced by HCl/ethanol, absolute ethanol, stress, non-steroidal anti-inflammatory drugs, and pylorus ligation in male rats or mice. Cd-EtOHE and Cd-HexP significantly reduced gastric injuries induced in all models. Cd-EtOHE and Cd-HexP did not alter gastric juice parameters such as pH, [H(+)], or volume after pylorus ligation. Cytoprotective mechanisms of Cd-EtOHE and Cd-HexP in relation to mucus, nitric oxide (NO), and sulfhydryl (SH) groups were evaluated. Neither product increased the mucus, and they both showed dependence on NO and SH groups to prevent gastric ulcer. Both Cd-EtOHE and Cd-HexP demonstrated gastroprotective activity.

Abstract
Peptic ulcer is the most common gastrointestinal tract (GIT) disorder in clinical practice, which affects approximately 5-10% of the people during their life. The use of herbal drugs for the prevention and treatment of various diseases is constantly developing throughout the world. This is particularly true with regard to phenolic compounds that probably constitute the largest group of plants secondary metabolites. Phenolic compounds have attracted special attention due to their health-promoting characteristics. In the past ten years a large number of the studies have been carried out on the effects of phenolic compounds on human health. Many studies have been carried out that strongly support the contribution of polyphenols to the prevention of cardiovascular diseases, cancer, osteoporosis, neurodegenerative diseases, and diabetes mellitus, and suggest a role in the prevention of peptic ulcer. Polyphenols display a number of pharmacological properties in the GIT area, acting as antisecretory, cytoprotective, and antioxidant agents. The antioxidant properties of phenolic compounds have been widely studied, but it has become clear that their mechanisms of action go beyond the modulation of oxidative stress. Various polyphenolic compounds have been reported for their anti-ulcerogenic activity with a good level of gastric protection. Besides their action as gastroprotective, these phenolic compounds can be an alternative for the treatment of gastric ulcers. Therefore, considering the important role of polyphenolic compounds in the prevention or reduction of gastric lesions induced by different ulcerogenic agents, in this review, we have summarized the literature on some potent antiulcer plants, such as, Oroxylum indicum, Zingiber officinale, Olea europaea L., Foeniculum vulgare, Alchornea glandulosa, Tephrosia purpurea, and so on, containing phenolic compounds, namely, baicalein, cinnamic acid, oleuropein, rutin, quercetin, and tephrosin, respectively, as active constituents.

[PMID: 21296139 DOI: 10.1016/j.jep.2011.01.052] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2010] [Revised: 01/15/2011] [Accepted: 01/28/2011] [Indexed: 05/30/2023]
Abstract
AIM OF THE STUDY Quassia amara L. is commonly used in Costarican folk medicine. It has been used for the treatment of a broad range of gastrointestinal symptoms such as dyspepsia, gastritis and constipation. In this study, the gastroprotective activity of two standardized extracts of Quassia amara L., Lipro(®) and Ligas(®), was evaluated. MATERIALS AND METHODS Anti-ulcerogenic properties were evaluated in female rats under acute ulcer-induction models (ethanol, indomethacin and hypotermic restraint). To get a deeper insight in the anti-ulcerogenic properties of the extracts, Ligas(®) was evaluated in the Shay rat model. Five parameters were estimated with this model: gastric mucus barrier, non-protein sulfhydril groups (NPSG) in the gastric mucosa, and pH, total acidity and peptic activity of the gastric juice. RESULTS Induction of ulcers by 95% ethanol (0.5 mL per os), indomethacin (100 mg/kgs.c.) and stress (2h in hypothermic restraint) was inhibited significantly with administration of Lipro(®) (p<0.05), in a dosage range from 4.9 mg/kg/d to 48.9 mg/kg/d. Treatment was given for one week. The extract Ligas(®) showed a significant augmentation of NPSG (p<0.05) in a dosage range from 4.0 to 39.7 mg/kg. Ligas(®) did not produce a significant change (p>0.05) in the other indicators. CONCLUSIONS Quassia amara L. standardized extracts, Lipro(®) and Ligas(®), showed an important anti-ulcerogenic effect in acute ulcer induction models. Their effect was related to an increase in gastric barrier mucus and non-protein sulfhydril groups.

Abstract
Reversed-phase preparative high-performance liquid chromatography (HPLC) of the methanol extract of the aerial parts of Euphorbia petiolata Banks & Soland, an endemic Iranian medicinal plant, yielded ten free radical scavengers including eight flavonoid glycosides myricetin 3-O-glucoside (1), kaempferol 3-O-(2-O-galloyl)-glucoside (2), myricetin 3-O-rhamnoside (3), quercetin 3-O-glucoside (4), kaempferol 3-O-glucoside (5), quercetin 3-O-rhamnoside (6), kaempferol 3-O-rhamnoside (7), and quercetin 3-O-rutinoside (10), a coumarin esculetin (8) and a phenylpropanoid 2-hydroxydihydrocinnamic acid (9). The structures of these compounds were elucidated conclusively by spectroscopic means and also by direct comparison of their spectroscopic data with respective published data. The free radical scavenging properties of these compounds were assessed by the 2,2-diphenyl-1-picrylhydrazyl assay.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Abarema cochliacarpos (Gomes) Barneby & Grimes (Mimosaceae) is a species--in folk medicine of Lagarto city, Sergipe state, northeastern Brazil--reputed to heal gastric ulcer and gastritis. AIM OF THE STUDY Chloroform (CE) and methanolic (ME) extracts as well as ethyl acetate fraction (AF), butanolic fraction (AC) and aqueous fraction (AQF) of the methanolic extract of Abarema cochliacarpos bark were evaluated against acute gastric ulcer. The AC fraction was selected to assess its activity in ulcer healing and its gastroprotective effects via mucus and gastric secretion. MATERIAL AND METHODS The gastroprotective action of CE and ME extracts and the fractions of the latter were evaluated in a rodent experimental model. The action mechanisms, involvements of the antisecretory action and mucus production, toxicological and healing activity of the AC (150 mg/kg, p.o.) were evaluated. We also used histological analysis (HE and PAS) and immunohistochemical (PCNA, COX-2, VEGF and HSP-70) assays to evaluate the effects of Abarema cochliacarpos. RESULTS CE (200 and 400 mg/kg, p.o.) and ME (100, 200 and 400 mg/kg, p.o.) extracts were able to protect gastric mucosa against absolute ethanol. Respective inhibitions produced were: 65.31% and 83.80% by the first; 91.69%, 96.75% and 99.80% by the second; and 74.24% by the AC fraction. Antisecretory and mucus production effects were exhibited by the AC fraction, which also accelerated the healing of ulcerated gastric mucosa by stimulating proliferation factors (PCNA) and induced healing factors including COX-2, VEGF and HSP-70. CONCLUSION All these results suggest that Abarema cochliacarpos (Gomes) Barneby & Grimes presents gastroprotective effects and wound-healing properties.

Abstract
Phenolic compounds are produced by secretory idioblasts and hypodermis, and by specialized cells of the epidermis and chlorenchyma of leaves of Alchornea triplinervia. Phytochemical investigation of these leaves led to the isolation of the known substances quercetin, quercetin-7- O-β-D-ghicopyranoside, quercetin-3- O-β-D-glucopyranoside, quercetin-3- O-β-D-galactopyranoside, quercetin-3- O-α-L-arabinopyranoside, amentoflavone, brevifolin carboxylic acid, gallic acid, and methyl gallate from the methanolic extract, and stigmasterol, campesterol, sitosterol, lupeol, friedelan-3-ol, and friedelan-3-one from the chloroform extract. In studies of antibacterial activity and mutagenicity, the methanolic extract showed promising activity against Staphylococcus aureus (MIC=62.5 μg/mL) and was slightly mutagenic in vitro and in vivo at the highest concentrations tested (1335 mg/kg b.w.).

Abstract
Abstract
Aim
Recurrent aphthous ulceration is the most commonly known oral mucosal disease. Quercetin is a useful therapeutic agent for the treatment of colitis and gastric ulcer. The objective of this study was to determine the effect of topical application of quercetin in the treatment of minor aphthous ulcers.
Methods and Materials
Forty male patients with no known pathology of the oral mucosa other than minor aphthous ulcers were enrolled in this study. Patients were randomly divided into two groups, each consisting of 20 patients. Group 1 (control group) patients used a benzydamine hydrochloride mouthwash three times daily. Group 2 patients placed two to three dabs of quercetin three times daily directly on their ulcers. Clinical evaluation of patients included assessment of ulcer size, pain measure, and interviews regarding the topical application of quercetin in terms of consistency, taste, local tolerability, and ease of application.
Results
The topical application of quercetin cream to minor mouth ulcers relieved pain and produced complete healing in seven of the Group 2 patients (35 percent) in 2–4 days, 18 patients (90 percent) in 4–7 days, and 20 patients (100 percent) in 7–10 days. When comparing the mean ulcer size after 10 days, lesions in the Group 2 patients were smaller than those in Group 1, and the size difference between the two groups was significantly different (p<0.004). Also, 90 percent of patients responded that they appreciated the ease of application when using the topical quercetin, and they did not object to its consistency or taste.
Conclusion
Quercetin is a safe, well-tolerated, and highly effective promising new, adjunctive treatment for healing common aphthous ulcers.
Clinical Significance
Although aphthous ulcers typically resolve on their own in one to two weeks, the daily topical application of quercetin may be useful in accelerating the healing process of minor aphthous ulcers.

Abstract
Among the current treatment strategies for the peptic ulcer patient with Helicobacter pylori infection, the method of choice is triple therapy based on the concurrent use of proton inhibitors and two antibiotics. Alchornea triplinervia is a medicinal plant commonly used by people living in the Cerrado region of Brazil to treat gastrointestinal ulcers. In the present work we proposed therapy based on this medicinal plant that presents effective gastroprotective action with antibiotic effects. Oral pretreatment with methanolic extract (ME) of A. triplinervia in rats and mice decreased the gastric injuries induced by ethanol and HCl/ethanol. Increasing the dose reduced the gastroprotective effects of ME on the gastric lesions induced by nonsteroidal anti-inflammatory drug. After pylorus ligature of mice, oral administration of ME induced a decrease not only in total acid but also in the ulcer index. We also observed that ME displayed antibacterial activity against H. pylori. Liquid-liquid separation of ME indicated that active constituents responsible for the gastroprotective action are concentrated in the ethyl acetate fraction (EAF) (50% protection) rather than in the aqueous fraction, which did not induce significant gastroprotection at the same dose (100 mg/kg). EAF induced an increase of gastric mucosa prostaglandin (PG) E(2) levels, which remained high even after previous administration of indomethacin. The phytochemical profile of ME revealed that EAF contains mainly flavonoids. In conclusion, all these results suggest that ME did not show acute toxicity, but exhibited an antisecretory property, anti-H. pylori effect, and gastroprotective action. The observed effect did not involve the participation of nitric oxide or endogenous sulfhydryl groups. However, EAF showed a more efficient gastroprotective effect than ME at a lower dose and protected the gastric mucosa by increasing PGE(2).

Abstract
Peptic ulcer, one of the most common gastrointestinal diseases, is a chronic inflammatory disease characterized by ulceration in the regions of the upper gastrointestinal tract where parietal cells are found and where they secrete hydrochloric acid and pepsin. The anatomical sites where ulcer occurs commonly are stomach and duodenum, causing gastric and duodenal ulcer, respectively. Physiopathology of ulcer is due to an imbalance between aggressive factors, such as acid, pepsin, Helicobacter pylori and non-steroidal anti-inflammatory agents, and local mucosal defensive factors, such as mucus bicarbonate, blood flow and prostaglandins. Several drugs are widely used to prevent or treat gastro-duodenal ulcers. These include H2-receptor antagonists, proton pump inhibitors and cytoprotectives. Due to problems associated with recurrence after treatment, there is therefore the need to seek alternative drug sources against ulcers. In recent years, a widespread search has been launched to identify new gastroprotective drugs from natural sources. The aim of the present review is to highlight the recent advances in current knowledge on natural products as gastroprotective and antiulcer agents and consider the future perspectives for the use of these compounds.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mouriri pusa Gardn. (Melastomataceae) is a medicinal plant commonly used by people living in the Cerrado to treat gastrointestinal disturbances. This medicinal plant has shown intense gastroprotective action in rodent gastric lesion, but still there are no data about its healing effect on gastric mucosa. AIM OF THE STUDY To evaluate the methanolic extract (MeOH) obtained from Mouriri pusa leaves for its effect on the cicatrisation process of gastric ulcer. MATERIALS AND METHODS The healing effects on gastric ulcers inducted by subserosal injection of acetic acid were evaluated by macroscopic and microscopic measures, immunohistochemistry and cell counting in rats treated with MeOH extract of Mouriri pusa (250 mg/kg, p.o./daily) for 14 or 30 days. The toxicity of Mouriri pusa was also evaluated by body and organ weight measure and clinical biochemical parameters. RESULTS Mouriri pusa treatments lasting 14 and 30 days showed elevated mucus secretion (PAS) and thicker regenerative gastric mucosa, denoting increased cell proliferation, which was confirmed by PCNA immunohistochemical analysis. Moreover, there was important cell recruitment (neutrophils and mast cells) to the site of the ulcer, which is an important factor in ulcer healing. No toxic effect was observed in all parameters evaluated. Phenolic compounds present in the MeOH extract like tannins, flavonoids and epicatechin are the probable agents involved in the healing effects of this medicinal plant. CONCLUSIONS These findings showed a potential effect of Mouriri pusa in increasing regeneration of damaged gastric mucosa with safety for human use.
