ABSTRACT
Introdução: A crença de que o uso de Inibidores de Bomba de Prótons (IBPs) apresenta baixo risco de toxicidade, resultou em um aumento significativo na sua prescrição em nível mundial, esse fator juntamente com a baixa divulgação de orientações, têm contribuído para o aumento das indicações desnecessárias de inibidores de bomba de prótons em nível hospitalar, principalmente para profilaxia. Objetivo: Analisar a utilização dos inibidores de bomba de prótons em pacientes internados nas enfermarias de clínica médica de um Hospital Universitário, visando avaliar suas indicações, tempo de uso, efeitos adversos e impacto financeiro gerado pelo uso inadequado. Métodos: Foram analisados prontuários de pacientes que estiveram internados nas enfermarias de clínica médica do Hospital Municipal Universitário de Taubaté (HMUT) durante os meses de maio a julho de 2020. As indicações adequadas do uso de inibidores de bomba de prótons foram baseadas em diretrizes internacionais do American Journal of Gastroenterology e do American Society of Health-System Pharmacy. Resultados: Identificamos que 297 pacientes (79,6%) usaram inibidores de bomba de prótons em algum momento da internação. O uso desse medicamento foi adequadamente prescrito em 49,8% dos casos. Foi encontrado maior prevalência de pneumonia e diarreia nos pacientes que fizeram uso de inibidores de bomba de prótons a longo prazo. O custo anual associado as prescrições indevidas foram de R$24.736,40. Conclusão: Observamos alta prevalência de indicações incorretas dos inibidores de bomba de prótons em ambiente hospitalar, ocasionando gasto desnecessário e possíveis complicações. Faz-se necessário, portanto, elaboração de novos protocolos e maior rigidez nas indicações desses medicamentos no Hospital Municipal Universitário de Taubaté.
Introduction: The belief that the use of Proton Pump Inhibitors (PPIs) presents a low risk of toxicity, resulted in a significant increase in its prescription worldwide, this factor combined with the low disclosure of guidelines, have contributed to the increase in unnecessary indications of at the hospital level, especially for prophylaxis. Objective: To analyze the use of proton pump inhibitors in patients hospitalized in the medical clinic wards of a University Hospital, in order to evaluate their indications, time of use, adverse effects and financial impact generated by inadequate use. Methods: Medical records of patients who were admitted at the Municipal University Hospital of Taubaté during the months of May to July 2020 were analyzed. The appropriate indications for the use of proton pump inhibitors were based on the international guidelines of the American Journal of Gastroenterology and the American Society of Health-System Pharmacy. Results: We identified that 297 patients (79.6%) used proton pump inhibitors at some point in hospitalization. The use of this drug was adequately prescribed in 49.8% of the cases. A higher prevalence of pneumonia and diarrhea was found in patients who used proton pump inhibitors in the long term. The annual cost associated with undue prescriptions was R$24,736.40. Conclusion: We observed a high prevalence of incorrect indications of proton pump inhibitors s in the hospital environment, causing unnecessary expenses and possible complications. It is necessary, therefore, the elaboration of new protocols and greater rigidity in the indications of these drugs at the Municipal University Hospital of Taubaté.

RESUMO Objetivo: Avaliar a adesão ao protocolo de profilaxia de úlcera de estresse em pacientes críticos de um hospital universitário terciário. Métodos: Neste estudo de coorte prospectiva, incluímos todos os pacientes adultos admitidos às unidades de terapia intensiva clínica e cirúrgica de um hospital terciário acadêmico. Nosso único critério de exclusão foi a presença de sangramento gastrointestinal alto quando da admissão à unidade de terapia intensiva. Colhemos as variáveis basais e indicações de profilaxia de úlcera de estresse, segundo o protocolo institucional, assim como o uso de profilaxia. Nosso desfecho primário foi a adesão ao protocolo de profilaxia de úlcera de estresse. Os desfechos secundários foram uso apropriado da profilaxia de úlcera de estresse, incidência de sangramento gastrointestinal superior e fatores associados com o uso apropriado da profilaxia de úlcera de estresse. Resultados: Foram incluídos 234 pacientes no período compreendido entre 2 de julho e 31 de julho de 2018. Os pacientes tinham idade de 52 ± 20 anos, sendo 125 (53%) deles cirúrgicos, e o SAPS 3 médio foi de 52 ± 20. No seguimento longitudinal, foram estudados 1.499 pacientes-dias; 1.069 pacientes-dias tiveram indicação de profilaxia de úlcera de estresse, e 777 pacientes-dias tiveram uso profilático (73% de adesão ao protocolo de profilaxia de úlcera de estresse). Dentre os 430 pacientes-dias sem indicações de profilaxia de úlcera de estresse, 242 envolveram profilaxia (56% de uso impróprio de profilaxia de úlcera de estresse). O total de uso apropriado de profilaxia de úlcera de estresse foi de 64%. Fatores associados com prescrição adequada de profilaxia de úlcera de estresse foram ventilação mecânica, com RC 2,13 (IC95% 1,64 - 2,75), e coagulopatia, com RC 2,77 (IC95% 1,66 - 4,60). A incidência de sangramento do trato gastrointestinal superior foi de 12,8%. Conclusão: A adesão ao protocolo de profilaxia de úlcera de estresse foi baixa, e o uso inadequado de profilaxia de úlcera de estresse foi frequente nesta coorte de pacientes críticos.
ABSTRACT Objective: To evaluate adherence to the stress ulcer prophylaxis protocol in critically ill patients at a tertiary university hospital. Methods: In this prospective cohort study, we included all adult patients admitted to the medical and surgical intensive care units of an academic tertiary hospital. Our sole exclusion criterion was upper gastrointestinal bleeding at intensive care unit admission. We collected baseline variables and stress ulcer prophylaxis indications according to the institutional protocol and use of prophylaxis. Our primary outcome was adherence to the stress ulcer prophylaxis protocol. Secondary outcomes were appropriate use of stress ulcer prophylaxis, upper gastrointestinal bleeding incidence and factors associated with appropriate use of stress ulcer prophylaxis. Results: Two hundred thirty-four patients were enrolled from July 2nd through July 31st, 2018. Patients were 52 ± 20 years old, 125 (53%) were surgical patients, and the mean SAPS 3 was 52 ± 20. In the longitudinal follow-up, 1499 patient-days were studied; 1069 patient-days had stress ulcer prophylaxis indications, and 777 patient-days contained prophylaxis use (73% stress ulcer prophylaxis protocol adherence). Of the 430 patient-days without stress ulcer prophylaxis indications, 242 involved prophylaxis (56% inappropriate stress ulcer prophylaxis use). The overall appropriate use of stress ulcer prophylaxis was 64%. Factors associated with proper stress ulcer prophylaxis prescription were mechanical ventilation OR 2.13 (95%CI 1.64 - 2.75) and coagulopathy OR 2.77 (95%CI 1.66 - 4.60). The upper gastrointestinal bleeding incidence was 12.8%. Conclusion: Adherence to the stress ulcer prophylaxis protocol was low and inappropriate use of stress ulcer prophylaxis was frequent in this cohort of critically ill patients.

Acid peptic disorders, especially hyperacidity is not uncommon in the current era because of altered life style of human being. In India prevalence of H. Pyloric infection in young age is 83.8%. Peptic ulcer occurs at young age with highest incidence between 20-40 years, men are affected more than women. If these Acid peptic disorders are not treated in time, it may lead to peptic ulcer, haematemasis, malena and perforation of duodenal ulcer which are common now a day with 50% mortality. Generally it is accepted that gastric ulcers result from an imbalance between aggressive factors and the maintenance of the mucosal integrity through endogenous defense mechanisms. Use of synthetic antiulcer drugs may damage to the cell membrane of mucosal, parietal and endothelial cells. To avoid such hazards, it is essential to find out some antiulcer agents from Ayurvedic treasure of therapeutics. Ancient sages have explained many herbal preparations which are beneficial in pain in abdomen (Shoola) and/or hyperacidity (Amlapitta) etc. Jambira (Citrus limon Linn.), mentioned as Shoola-hara (pain relieving) drug in Ayurvedic classics, is abundantly available and cost effective drug and may satisfy the need of present day situation by acting as potent herbal antacid drug. With this perspective, the study was taken for the critical assessment of gastric anti-secretory and anti-ulcer activity of Jambira (Citrus limon Linn.) as an experimental study but the results of experimental study did not support that Jambira (Citrus limon Linn.) fruit juice is a potent antisecretory and antiulcer natural source compared to control in pylorus ligation rat model.

ABSTRACT BACKGROUND: Extracts obtained from plants and fruits provide a relatively safe and practical alternative for the conventional medicine of gastrointestinal diseases. The specie Eugenia mattosii, popularly known in Brazil as "cerejinha", belongs to Myrtaceae family. Species of this family present pharmacological properties, and can be used in the treatment of gastrointestinal disorders. OBJECTIVE: The aim of this study was to determine the phytochemical profile and evaluate the gastroprotective activity of Eugenia mattosii fruits. METHODS: Phytochemical analysis was carried out by thin layer chromatography and gastroprotective assays were performed using two experimental models: acute ulcer model induced by ethanol/HCl and acute ulcer model induced by non-steroidal anti-inflammatory drug (indomethacin). Total lesion area (mm2) and relative lesion area (%) were determined. RESULTS: The results of the phytochemical analysis indicated that the bark and pulp and seeds of E. mattosii present phenolic compounds, terpenes and/or steroids. In gastric ulcer model induced by ethanol was evidenced significant reduction of damaged areas for doses of 50 and 250 mg/ kg of seeds methanol extract, while in the indomethacin-induced ulcer model, all parts of the fruit presented defense capability of the gastric mucosa by reducing lesions at doses of 50, 125 and 250 mg/kg. CONCLUSION: The results demonstrate that the specie E. mattosii has bioactive compounds that provide gastroprotective activity, presenting possible therapeutic potential.

ABSTRACT
ABSTRACT In order to compile the empirical use, as well as the chemical, pharmacological and biological aspects of Himatanthus drasticus (Mart.) Plumel, Apocynaceae, a review was carried out by searching PubMed, Google Scholar, Scientific Electronic Online Library, Web of Science, Science Direct, Scopus and Cochrane. For that, works in English, Spanish and Portuguese, preclinical studies and revisions, addressing chemical, pharmacological, biological properties and popular uses, from 1994 to 2017, were used. The therapeutic potential of the "milk-of-janaguba" (a mixture of the latex with water) became widely known for the treatment of neoplasias, mainly lung and lymphatic cancer types, in the 1970s. The available literature presents works related to the anti-inflammatory, antinociceptive, antitumor and gastroprotective properties of the latex from bark and leaves of H. drasticus. In addition, this review presents some of our own results with the triterpene-rich fraction from H. drasticus, attempting to clarify its action mechanisms at the molecular level. The antinociceptive and anti-inflammatory activities of H. drasticus are probably associated with inhibitions of inflammatory mediators, as TNF-alpha, iNOS, COX-2 and NF-kB. Most importantly, a triterpene-rich fraction also inhibited HDAC activity, and compounds with this activity have been considered as therapeutic agents with antitumor activity. In conclusion, although the literature shows several works on species of the Himatanthus genus, including H. drasticus, dealing with some bioactive compounds as triterpenes, translational studies focusing upon the clinical uses of this medicinal species are still in great need.
ABSTRACT
RESUMEN La información actual sobre el uso de inhibidores de la producción de ácido clorhídrico (inhibidores de bomba de protones y antagonistas de los receptores de histamina H2), en pacientes no críticos hospitalizados para la profilaxis de úlceras por estrés es controversial. Con el fin de evaluar la pertinencia de este grupo de medicamentos en conformidad con el riesgo de sangrado gastrointestinal medido por la escala de Herzig et al. {Risk factors for nosocomial gastrointestinal bleeding and use of acid-suppres-sive medication in non-critically ill patients, J. Gen. Intern. Med, 28(5), 683-690 (2013)}, se realizó un estudio observacional descriptivo longitudinal con recolección retrospectiva de la información, el cual incluyó todos los pacientes mayores de 18 años sin sangrado gastrointestinal y con más de tres días de hospitalización, en el servicio de medicina interna de un hospital de tercer nivel de Bogotá. Según esta escala, el 64% de los pacientes se clasificó en bajo riesgo, el 22,3% en medio-bajo, el 6,7% en medio-alto, y el 6,7% en alto. La prescripción profiláctica de inhibidores de la secreción ácida se realizó en el 67% de los pacientes de bajo riesgo, en el 57% de los de medio-bajo y en el 100% de los pacientes de riesgo medio-alto y alto. Cerca de la mitad (55,35%) de los pacientes recibieron un antiulceroso sin requerirlo; por lo tanto, se recomienda realizar actividades educativas dirigidas al personal prescriptor, con el fin de hacer un uso adecuado de este grupo de medicamentos.
SUMMARY Current information on the use of inhibitors of the production of hydrochloric acid (proton-pump inhibitor (PPI) ATC A02BC and histamine H2 receptor antagonists (Anti H2) ATC A02BC) in non-critical patients for the prophylaxis of stress ulcers is controversial. A descriptive longitudinal observational study with a retrospective collection of information, that included patients over 18 years with more than three days of hospitalization in internal medicine, without active gastrointestinal bleeding using the scale of Herzig et al. {Risk factors for nosocomial gastrointestinal bleeding and use of acid-suppressive medication in non-critically ill patients, J. Gen. Intern. Med., 28(5), 683-690 (2013)}, to assess the risk gastrointestinal bleeding was carried out. According to the risk score, patients were classified 64% as low risk, 22.3% medium-low risk, 6.7% medium-high risk and 6.7% high risk. Prophylactic prescription inhibiting acid secretion was performed in 67% of patients at low risk, 57% in medium-low risk and 100% for patients with medium-high and high risk. More than half (55.33%) of the patients received a PPI/anti H2 without requiring it. Educational activities are recommended to the prescribing staff in order to make proper use of this group of drugs.
ABSTRACT
Delonix regia, commonly called Flame Tree or Flamboyant (locally, Gul Mohor) is a common tree traditionally used to treat various diseases like gastric problems, body pain, rheumatic pains of joints and wound healing. Here, we carried out biological profiling of Delonix regia as antiulcer agent. Antiulcer activity of the ethanol extract from stem bark was evaluated on pylorus ligation and indomethacin induced ulcer in Wistar albino rats. Ethanol extract from stem bark of D.regia was administered at the doses 100, 200 and 400 mg/kg/day, p.o. for 7 days. Ulcer index, gastric pH, volume, free acidity, total acidity, total carbohydrate (TC), protein (P), mucin content (TC/P) and gastric mucus were evaluated in pylorus ligation model, while ulcer index, malondialdehyde, GSH, PGE2, and gastric mucus were estimated in the indomethacin induced ulcer model. Ex vivo assay for the activity of H+/K+-ATPase was also done. The results showed significant inhibition on H+/K+-ATPase in a dose dependent manner and comparableto their respective positive control group of rats demonstrating that ethanol extract of stem bark of Delonix regia possesses significant antiulcer properties.
ABSTRACT
Objective To investigate the short-term efficacy of compound gargle solution chlorhexidine giuconatie and kangfuxin liquid in treatment of recurrent aphthous ulcer (RAU).Methods Eighty patients clinically diagnosed with RAU were chosen and randomly divided into two groups.Test group 1 (40 cases) and Test group 2 (40 cases) were treated with compound gargle solution chlorhexidine giuconatie and kangfuxin liquid respectively until ulcer has been healed completely to evaluate the difference of two groups in clinical efficacy.Return visit and follow-up visit were conducted 7 days and 30 days after the initial treatment,respectively.Results The analgesic onset time of Test group 1 [(6.24 ± 1.09) min] was shorter than that of Test group 2 [(8.62 ± 1.04) min],with statistically significant difference (P ＜ 0.01).The analgesic maintenance time of Test group 1 [(29.47 ± 3.45) min] was longer than that of Test group 2 [(21.61 ±2.18) min],with statistically significant difference (all P ＜ 0.01).The duration of ulcer of Test groups 1 and 2 was (5.97-± 0.87)days and (4.76 ± 1.14)days,with statistically significant difference (P ＜0.01).Conclusions Compound gargle solution chlorhexidine giuconatie and kangfuxin liquid both have a certain level of clinical efficacy for RAU,with the former featuring shorter analgesic onset time and longer duration and the latter advantageous in promoting RAU healing short-term usage of compound gargle solution chlorhexidine giuconatie and kangfuxin liquid cannot prolong RAU dormancy.

ABSTRACT
The pharmacologic action of Atractylodis Rhizoma and its effective constituents in digestive system includes mainly anti-ulcer activity,acceleration of gastric emptying,regulation of gastrointestinal propellant movement,antidiarrheat effect,choleretic effect,hepatoprotection,and promotion of digestive and absorptive function.Atractylodis Rhizoma decreases gastric acid secretion via blockade of H2-receptor,and inhibits overexpression of inflammatory cytokines in gastric tissues to produce anti-ulcer effect.Atractylodis Rhizoma increases gastric mucosal blood flow,and improves growth and reparation of gastric mucosa to produce anti-ulcer effect by blockade of 5-TH receptor,and elevating levels of gastrin and trefoil factor in serum and gastric tissues.Atractylodis Rhizoma accelerating gastric emptying and gastrointestinal propellant movement is relative to decreasing release of central corticotropin-releasing factor,and stimulating vagal nerve,and promoting secretion of gastrin and motilin,and inhibiting secretion of vasoactive intestinal peptide,and blocking 5-HT-3receptor,and increasing amount of interstitial cell of Cajal.
ABSTRACT
In the present study, a new ceramide, namely 2S, 3R-4E, 8E-2-(heptadecanoylamino)-heptadeca-4, 8-diene-1, 3-diol (1), along with four known steroids, including 24-methylcholesta-5, 24(28)-diene-3β-ol (2), 24-methylcholesta-5, 24(28)-diene-3β-acetate (3), 4-methyl-24-methylcholesta-22-ene-3-ol (4), and cholesterol, was isolated and characterized from CHCl/MeOH extract of Cespitularia stolonifera. A new acetate derivative of compound 1, termed 2S, 3R-4E, 8E-2-(heptadecanoylamino)-heptadeca-4, 8-diene-1, 3-diacetate (1a), was also prepared in the present study. All the structures were established on the basis of modern spectroscopic techniques, including FT-IR, 1D, 2D-NMR, HRESI-MS, and GC-MS, in addition of chemical methods. (-)-Alloaromadendren, ledane, (1)-alloaromadendren oxide, isoaromadendrene epoxide and (-)-caryophellen oxide were identified from the n-hexane fraction using GC-MS. The extract and the two ceramides (1) and (1a) exhibited significant cytotoxic activity against lung cancer A549 cells, while the extract and the two steroids (2) and (3) exhibited significant cytotoxic activity against breast cancer MCF-7 cells. The CHCl/MeOH extract exhibited significant antiulcer activity in both ethanol and acetic acid induced ulcer models in rats, as evidenced by histopathological, histochemical, and biochemical examinations.

The neem (Azadirachta indica A. Juss) is a tropical evergreen tree (Fam. Meliacae; Subfam. Melioideae) traditionally well known for its medicinal value. Beneficialt effects of different parts of neem are attributed to its biologically active principle ‘Azadirachtin’. Apart from Indian subcontinent, neem is widely used in African countries as therapeutics, preservatives and insecticides. Neem leaves, natural source of flavonoids, polyphenols, isoprenoids, sulphurous and polysaccharides, play important role in scavenging the free radical and subsequently arresting disease pathogenesis. Considerable research has gone into neem for developing cost effective and non-toxic products. The present review has compiled different phytochemicals isolated from neem leaves, methods of extraction and their therapeutic use in preventing several diseases. Here, we highlighted the mechanism of anti-inflammatory and antioxidant activity of neem leaf that underscores the disease through regulation of physiological responses. Also, multiple roles of neem leaf and commercial use of neem formulation as an alternative in paving a frontier in the field of drug discovery are discussed.
ABSTRACT
Objetivo: el objetivo de este estudio fue describir y analizar los patrones de prescripción de fármacos antiulcerosos, los factores asociados a su prescripción y su costo en pacientes ambulatorios polimedicados en un período de 6 meses, en una Entidad Promotora de Salud (EPS) colombiana a nivel nacional. Metodología: estudio descriptivo retrospectivo de corte transversal, basado en registros electrónicos de prescripción de medicamentos ambulatorios de 2 458 447 afiliados. Se incluyeron pacientes con prescripción de 5 o más fármacos por mes y se excluyeron aquellos cuyos registros transaccionales no tenían información completa para su análisis. Se evaluó la asociación entre prescripción de fármacos antiulcerosos y factores que justifican su prescripción mediante los odds ratio (OR) calculados a partir de un modelo de regresión logística. Resultados: de 2 458 447 afiliados, 60 671 pacientes estuvieron polimedicados mensualmente; 40% tuvieron fármacos antiulcerosos y 70% fármacos gastrolesivos. De los gastroprotegidos, 47% fueron adultos mayores y 12% tuvieron asociado diagnóstico de riesgo gastrointestinal superior. Gastroprotección no justificada en 35% de los pacientes polimedicados, representando $75 millones de pesos colombianos (COP) mensuales. No hubo asociación estadística entre la prescripción de antiulcerosos y factores que justifiquen su prescripción (OR: 1,13; IC 95%: 1,00-1,27). Conclusión: ante la falta de asociación entre la prescripción de fármacos antiulcerosos y los factores que la justifican, es probable que su prescripción se haya realizado por la polifarmacia per se. Se recomienda optimizar la gastroprotección y reservarla a pacientes con más de un gastrolesivo y riesgo gastrointestinal superior, estén estos polimedicados o no.
Objective: The objective of this study was to describe and analyze patterns of use of prescription ulcer drugs, factors associated with prescriptions by physicians, and costs for outpatients With polypharmacy at a Colombian healthcare promotion entity (EPS) over a six-month period. Methodology: This is a retrospective and descriptive cross-sectional study based on electronic records of drugs prescribed to 2,458,447 outpatient members. Patients who took five or more prescription drugs per month were included. Patient were excluded if their records in the transactional data were not complete enough for analysis. Associations between anti-ulcer drugs and factors justifying their prescription were evaluated by the odds ratio (OR) which was calculated from a logistic regression model. Results: Of the 2,458,447 affiliates of the EPS, on average 60,671 patients had polypharmacy each month: 40% used anti-ulcer drugs and 70% used gastro-damaging drugs. Of the gastroprotected patients, 47% were elderly and 12% had associated diagnoses of upper gastrointestinal risk. Gastroprotection was not justified in 35% of patients with polypharmacy. This represents 75 million Colombian pesos every month. There was no statistical association between prescription of anti-ulcer drugs and factors that justify their prescription (OR: 1.13; 95% CI: 1.00 to 1.27). Conclusion: Given the lack of association between prescription of anti-ulcer drugs and factors which justify such prescriptions, it is likely that prescriptions contribute to polypharmacy per se. We recommended optimizing gastroprotection by reserving it for patients with more than one gastrointestinal lesion and with upper gastrointestinal risks whether or not they have polypharmacy.

ABSTRACT
BACKGROUND/AIMS: The ability of endoscopic submucosal dissection (ESD) to resect large early gastric cancers (EGCs) results in the need to treat large artificial gastric ulcers. This study assessed whether the combination therapy of rebamipide plus a proton pump inhibitor (PPI) offered benefits over PPI monotherapy. METHODS: In this prospective, randomized, multicenter, open-label, and comparative study, patients who had undergone ESD for EGC or gastric adenoma were randomized into groups receiving either rabeprazole monotherapy (10 mg/day, n=64) or a combination of rabeprazole plus rebamipide (300 mg/day, n=66). The Scar stage (S stage) ratio after treatment was compared, and factors independently associated with ulcer healing were identified by using multivariate analyses. RESULTS: The S stage rates at 4 and 8 weeks were similar in the two groups, even in the subgroups of patients with large amounts of tissue resected and regardless of CYP2C19 genotype. Independent factors for ulcer healing were circumferential location of the tumor and resected tissue size; the type of treatment did not affect ulcer healing. CONCLUSIONS: Combination therapy with rebamipide and PPI had limited benefits compared with PPI monotherapy in the treatment of post-ESD gastric ulcer (UMIN Clinical Trials Registry, UMIN000007435).

The edible fruits of Pithecellobium dulce (Roxb.) Benth. are traditionally used for various gastric complications in India. Here, we investigated the antiulcer activity of hydroalcoholic fruit extract of P. dulce (HAEPD) by applying cysteamine induced duodenal ulcer model in rats. Duodenal ulcer was induced in male albino Wistar rats by oral administration of cysteamine @ 420 mg/kg body wt. as a single dose. The rats were pre-administered orally with HAEPD @ 200 mg/kg body wt. for 30 days prior to ulcer induction. Rats pre-administered with ranitidine @ 30 mg/kg body wt. served as reference drug control. Ulcer score, thiobarbituric acid reactive substances (TBARS), glycoproteins, superoxide dismutase, catalase and glutathione peroxidase and reduced glutathione levels were measured in the duodenum. Rats pre-administered with the HAEPD showed significantly reduced ulcer score comparable to that of ranitidine pretreated rats. The co-administration of HAEPD lowered the TBARS level and also restored the levels of glycoproteins, enzymatic and non-enzymatic antioxidants. Histopathological observations confirmed the presence of inflammation, necrosis and hemorrhagic spots in the duodenum of ulcer control rats which were significantly reduced due to HAEPD treatment. No abnormal alterations were observed in normal rats treated with HAEPD at the dosage studied. The results demonstrated antioxidant and cytoprotective nature of P. dulce, and thereby its significant anti ulcer property.
