Abstract
The numerous challenges and detrimental effects connected with the treatment of peptic ulcers in the world today calls for alternative attention. Ethnomedicinally, Dialium guineense pulp (DAGP) has numerous pharmacological activities. This study investigated the anti-ulcer activities of Dialium guineense pulp on gastric mucosa injury induced with aspirin in albino Wistar rats. DAGP extract was orally administered at doses of 250, 500 and 1000 mg/kg bw (mg per kg of the body weight) per day for 3 or 7 days followed by 400 mg/kg bw oral aspirin administration. Ulcer indices were determined, followed by a biochemical estimation of antioxidant enzymes using gastric mucosal tissue from the stomach. Student's t-test was used to compare significant differences among groups of animals at P ≤ 0.05. The results showed that Dialium guineense pulp caused a significant decrease (P ≤ 0.05) in the ulcer index in aspirin induced rats. This decrease in ulcer index is dose dependent and 1000 mg/kg bw per day caused the highest decrease in 7 days. The results showed a significant increase (P ≤ 0.05) in lipid peroxidation and a decrease (P ≤ 0.05) in antioxidant enzymes activities in the aspirin-induced ulcerated rats. Oral administration of DAGP increased antioxidant enzymes activities and decreased injury in the gastric mucosa in ulcer induced rats. Therefore, this study showed that DAGP exhibited anti-ulcer potential and that the gastrointestinal protection may be through the scavenging action of free radicals by its constituent antioxidants. Thus, Dialium guineense pulp has ameliorative medicinal potential for the curing of gastric disorders.

Abstract
Escitalopram, a drug of choice in the treatment of depression, was recently shown to possess an anti-inflammatory activity. The aim of the present study was to elucidate the effect of escitalopram on peripheral inflammatory cascades in iodoacetamide-induced colitis associated with depressive behavior in ovariectomized rats. Moreover, the role of α-7 nicotinic acetylcholine receptor in mediating the anti-colitic effect of escitalopram was examined using a nicotinic receptor antagonist methyllycaconitine citrate. Colitis was induced by intracolonic injection of 4% iodoacetamide in ovariectomized rats. Escitalopram (10 mg/kg/day, i.p.) was then injected for 1 week and several parameters including macroscopic (colon mass index and ulcerative area), microscopic (histopathology and scoring), and biochemical (myeloperoxidase and tumor necrosis factor-α) were determined. Colitis induction in ovariectomized rats resulted in a marked increase in colon mass index, ulcerative area, histopathological scoring, myeloperoxidase activity and tumor necrosis factor-α levels. These effects were ameliorated by escitalopram, even in the presence of methyllycaconitine indicating that α-7 nicotinic acetylcholine receptor does not mediate the anti-inflammatory effect of escitalopram. The present study revealed the beneficial effect of escitalopram in iodoacetamide induced colitis in ovariectomized rats and suggests that it may represent a new therapeutic agent for the treatment of inflammatory bowel disease, especially in patients with or at high risk of depressive behavior.

Abstract
INTRODUCTION Helicobacter pylori infection induces clinical symptoms in 15-20% of subjects, and the reason for this variation is still not clear. The aim of the present study is to evaluate the expression of tryptophan hydroxylase (TpH-1) in gastric mucosa of patients with symptomatic and asymptomatic H. pylori infection in relation to the intensity of bacterial colonization and severity of dyspeptic symptoms. MATERIAL AND METHODS Ninety subjects (aged 35-49 years) were enrolled in the study and separated into 3 groups of 30 subjects each. Group I - healthy volunteers without H. pylori infection, group II - subjects with asymptomatic H. pylori infection, group III - H. pylori-infected patients with dyspeptic symptoms, mainly fasting and nocturnal epigastric pain. To diagnose H. pylori infection the urea breath test (UBT-13C) and histological analysis were performed. The level of mRNA expression of tryptophan hydroxylase (TpH-1) was estimated in gastric mucosa with RT-PCR. RESULTS The expression of this enzyme in antral mucosa was 2.69 ±0.97 in group I, 2.28 ±0.69 in group II (p > 0.05) and 4.40 ±1.64 in group III (p < 0.001). The levels of expression of TpH-1 in gastric body mucosa were 2.16 ±0.70, 1.57 ±0.52 (p > 0.05) and 3.40 ±1.51 (p < 0.001), respectively. In group III a positive correlation was found between intensity of H. pylori colonization and TpH-1 expression as well as between TpH-1 expression and severity of dyspeptic symptoms. CONCLUSIONS Increased expression of TpH-1 in gastric mucosa plays a role in pathogenesis of chronic dyspepsia.

Abstract
Nowadays, gastric ulcers have become very common gastrointestinal disorders and numerous natural plant extracts exert promising anti-ulcerative effects. Therefore, this study was designed to evaluate the possible protective effect of dietary starch against ethanol induced gastric ulcers in mice. Post-administration of dietary starch for three consecutive days caused remarkable ameliorations in hemorrhagic lesions in gastric mucus and significant suppression in % incidence of ulceration, ulcer index and ulcer score induced by ethanol single administration. Indeed, deep ulceration, necrosis, disruption and degeneration in large areas of mucosa layer together with dense inflammatory cells infiltration and edema in sub-mucosal layer induced by ethanol administration were attenuated by starch post-administration and normalized the tissue architecture of the stomach. This potential protective effect could be attributed to the potent anti-oxidative capacity of starch that causes scavenger of the reactive oxygen species and thereby decreasing single and double DNA stranded break inductions and apoptotic DNA damage revealed by returning the p53 and caspase-3 expression levels to the normal level compared to the ethanol treated group. In conclusion, dietary starch has a potent therapeutic effect against ethanol induced gastric ulcer in mice via its free radical scavengers ability. Thus, we recommended further studies on its possible use as antiulcer drugs.

Abstract
We report a rare case of hemorrhagic gastric polyps resulting in anemia during long-term proton pump inhibitor (PPI) administration that endoscopically looked like a fundic gland polyp (FGP). A 44-year-old man presented complaining of anemia and tarry stools. Esophagogastroduodenoscopy (EGD) demonstrated multiple white edematous polyps in the corpus and antrum, which were considered to be FGPs. We attempted endoscopic hemostasis but hemorrhaging increased because of hemorrhagic polyps and vulnerable gastric mucosa. Re-bleeding occurred several times. Polyp resection was performed at 24 polyp sites. We also ceased the administration of PPI. Microscopically, polyps showed characteristics of hyperplasia in the foveolar epithelium, extensions of fundic glands, and edema of the stroma. The proliferation of parietal and chief cells was also observed. Immunohistochemically, aquaporin-4 (AQP4) and KCNQ1-positive parietal cells and dilated mucous glands were found from the basal side to the apical side of the mucosa. These findings were compatible with the development of lesions associated with the long-term administration of PPI. EGD revealed an improvement in the vulnerability of gastric mucosa and the development of polyps, with no further gastric polyps observed 1 year after discharge. Bleeding from polyps resembling FGPs is generally rare, with indications that long-term PPI administration may induce such bleeding.

Abstract
PURPOSE The correlation of fibromyalgia syndrome (FMS) with peptic ulcer disease (PUD) is unclear. We therefore conducted a cohort study to investigate whether FMS is correlated with an increased risk of PUD. METHODS In this study, we established an FMS cohort comprising 26068 patients aged more than 20 years who were diagnosed with FMS from 2000 to 2011. Furthermore, we established a control cohort by randomly choosing 104269 people without FMS who were matched to the FMS patients by gender, age, and index year. All patients were free of PUD at the baseline. Cox proportional hazard regressions were performed to compute the hazard ratio of PUD after adjustment for demographic characteristics and comorbidities. RESULTS The prevalence of comorbidities was significantly higher in the FMS patients than in the controls. The incidence of PUD was 29.8 and 19.4 per 1000 person-years in the FMS and control cohorts, respectively. In addition, the FMS cohort exhibited a 1.40-fold higher risk of PUD (95% confidence interval = 1.35-1.45) compared with the control cohort. After control for confounding factors, the medications (selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, and antidepressants) taken by the FMS patients did not increase the risk of PUD. CONCLUSION FMS patients exhibit a higher risk of PUD than that of patients without FMS.

Abstract
BACKGROUND We aimed in the present study, at investigating the gastroprotective effect of carob pods aqueous extract (CPAE) against ethanol-induced oxidative stress in rats as well as the mechanism implicated. METHODS Adult male wistar rats were used and divided into six groups of ten each: control, EtOH (80% v/v, 4 g/kg b.w.), EtOH 80% + various doses of CPAE (500, 1000 and 2000 mg/kg, b.w.) and EtOH + Famotidine (10 mg/kg, p.o.) Animals were perorally (p.o.) pre-treated with CPAE during 15 days and intoxicated with a single oral administration of EtOH (4 g/kg b.w.) for two hours. RESULTS The colorimetric analysis demonstrated that the CPAE exhibited an importance in vitro antioxidant activity against ABTS and DPPH radicals. We found that CPAE pretreatment in vivo, protected against EtOH-induced macroscopic and histological changes induced in stomach mucosa. Carob extract administration also protected against alcohol-induced volume gastric juice decrease. More importantly, We showed that CPAE counteracted EtOH-induced gastric lipoperoxidation, reversed the decrease of sulfhydryl groups (-SH) an hydrogen peroxide (H2O2) levels, and prevented the depletion of antioxidant enzyme activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). CONCLUSIONS These findings suggest that CPAE exerted a potential gastro-protective effect against EtOH-induced oxidative stress in rats, due in part, to its antioxidants properties.

Abstract
High prevalence of psychological comorbidities such as depression and anxiety in patients with inflammatory bowel disease (IBD) supports the premise that adding an anti-depressant drug with known anti-inflammatory effect to the medical treatment have beneficial effect in the course of the underlying disease. Colitis was induced by intracolonic instillation of 2 ml of 4% v/v acetic acid solution in rats. Anti-colitic effect of fluvoxamine was evaluated in two categories: A: normal rats, B: reserpinized (6 mg/kg, i.p.) depressed rats. In group A, fluvoxamine (2.5, 5, 10 mg/kg, i.p.) was administered 2 h after induction of colitis and in group B: reserpine (6 mg/kg, i.p.) was administered 1 h prior to colitis induction and then fluvoxamine (2.5, 5, 10 mg/kg, i.p.) was administered 2 h after colitis induction. Dexamethasone (1 mg/kg) was used as reference drug. All the treatments continued daily for five days. The effect was assessed on the basis of macroscopic score, biochemical (myeloperoxidase) changes and histopathological studies. Results showed that fluvoxamine (2.5 and 5 mg/kg) and dexamethasone treatment markedly reduced disease severity in both reserpinized and non-reserpinized rats as indicated by reduction in macroscopic and microscopic colonic damages while reserpine adversely exacerbated the colitis damage. Myeloperoxidase activity which was increased following colitis induction was also decreased. The findings of this study elucidate the anti-colitic and anti-inflammatory properties of fluvoxamine and so introduced it as a good candidate to treat depressive symptoms in people comorbid to IBD.

Acute toxicity and gastroprotective role of M. pruriens in ethanol-induced gastric mucosal injuries in rats. BIOMED RESEARCH INTERNATIONAL 2013; 2013:974185. [PMID: 23781513 PMCID: PMC3678452 DOI: 10.1155/2013/974185] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/05/2013] [Revised: 04/27/2013] [Accepted: 05/01/2013] [Indexed: 12/29/2022]
Abstract
The investigation was to evaluate gastroprotective effects of ethanolic extract of M. pruriens leaves on ethanol-induced gastric mucosal injuries in rats. Forty-eight rats were divided into 8 groups: negative control, extract control, ulcer control, reference control, and four experimental groups. As a pretreatment, the negative control and the ulcer control groups were orally administered carboxymethylcellulose (CMC). The reference control was administered omeprazole orally (20 mg/kg). The ethanolic extract of M. pruriens leaves was given orally to the extract control group (500 mg/kg) and the experimental groups (62.5, 125, 250, and 500 mg/kg). After 1 h, CMC was given orally to the negative and the extract control groups. The other groups received absolute ethanol. The rats were sacrificed after 1 h. The ulcer control group exhibited significant mucosal injuries with decreased gastric wall mucus and severe damage to the gastric mucosa. The extract caused upregulation of Hsp70 protein, downregulation of Bax protein, and intense periodic acid schiff uptake of glandular portion of stomach. Gastric mucosal homogenate showed significant antioxidant properties with increase in synthesis of PGE2, while MDA was significantly decreased. The ethanolic extract of M. pruriens leaves was nontoxic (<5 g/kg) and could enhance defensive mechanisms against hemorrhagic mucosal lesions.

Abstract
BACKGROUND The current study was carried out to examine the gastroprotective effects of Parkia speciosa against ethanol-induced gastric mucosa injury in rats. METHODOLOGY/PRINCIPAL FINDINGS Sprague Dawley rats were separated into 7 groups. Groups 1-2 were orally challenged with carboxymethylcellulose (CMC); group 3 received 20 mg/kg omeprazole and groups 4-7 received 50, 100, 200 and 400 mg/kg of ethanolic leaf extract, respectively. After 1 h, CMC or absolute ethanol was given orally to groups 2-7. The rats were sacrificed after 1 h. Then, the injuries to the gastric mucosa were estimated through assessment of the gastric wall mucus, the gross appearance of ulcer areas, histology, immunohistochemistry and enzymatic assays. Group 2 exhibited significant mucosal injuries, with reduced gastric wall mucus and severe damage to the gastric mucosa, whereas reductions in mucosal injury were observed for groups 4-7. Groups 3-7 demonstrated a reversal in the decrease in Periodic acid-Schiff (PAS) staining induced by ethanol. No symptoms of toxicity or death were observed during the acute toxicity tests. CONCLUSION Treatment with the extract led to the upregulation of heat-shock protein 70 (HSP70) and the downregulation of the pro-apoptotic protein BAX. Significant increases in the levels of the antioxidant defense enzymes glutathione (GSH) and superoxide dismutase (SOD) in the gastric mucosal homogenate were observed, whereas that of a lipid peroxidation marker (MDA) was significantly decreased. Significance was defined as p<0.05 compared to the ulcer control group (Group 2).

Abstract
Compared to the well-known anti-ulcerogenic properties of tricyclic antidepressants, the impact of selective serotonin reuptake inhibitors (SSRIs) on gastric mucosa is less clear. Human clinical trials have shown that SSRIs and non-steroidal anti-inflammatory drugs (NSAIDs) act synergistically and promote stomach ulcer formation and upper gastrointestinal tract bleeding. Acute SSRI treatment confers an additional risk for the formation of NSAID-induced gastric ulcers through increase in gastric acid secretion. Stress, which is often experienced by depressed patients, also deteriorates the gastric environment. Thus the potential for exacerbating stress-induced gastric lesions must be considered before prescribing SSRIs. Therefore, we evaluated the effects of paroxetine by using a water-immersion stress-induced stomach ulcer model of mice, by examining single vs. repeated paroxetine treatments for 8 and 22 days before stress induction. Repeated administration of paroxetine significantly decreased the area of stress-induced stomach lesions. Although stress significantly increased the serum corticosterone concentrations, the levels were not affected by the 8-day paroxetine treatment. We confirmed the anxiolytic and antidepressive effects of 8-day paroxetine treatment at 1 and 5 days after stress induction by using the elevated plus-maze and tail-suspension tests. We concluded that repeated paroxetine treatment significantly attenuates the stress-induced ulcerogenic process in the stomach.

Abstract
Recent clinical studies have suggested a risk of adverse gastric reactions from the concomitant use of selective serotonin (5-HT) reuptake inhibitors (SSRIs) with nonsteroidal anti-inflammatory drugs (NSAIDs). We examined the adverse effects of SSRIs on antral lesions produced by indomethacin in rats. Rats fasted for 24 h were refed for 1 h, then administered indomethacin (30 mg/kg s.c.) 1 h after the refeeding and killed 6 h later. Paroxetine (1-10 mg/kg) was given orally 30 min before indomethacin. Indomethacin caused antral lesions in refed rats. Paroxetine dose-dependently aggravated these lesions, despite provoking no damage by itself. Similar results were obtained when other NSAIDs such as diclofenac, flurbiprofen, and loxoprofen were coadministered with paroxetine or when indomethacin was coadministered with other antidepressants such as fluvoxamine and milnacipran, but not imipramine or maprotiline. Exogenous 5-HT also worsened the indomethacin-induced antral damage, whereas the aggravating effect of paroxetine was attenuated by ondansetron, a selective 5-HT(3) antagonist, but not antagonists for other 5-HT receptor subtypes. Indomethacin plus paroxetine had no effect on gastric secretion but significantly decreased mucosal superoxide dismutase (SOD) activity as well as GSH content. The antral damage induced by indomethacin plus paroxetine was significantly prevented by antisecretory (acid or pepsin) agents and mucosal protective agents as well as SOD and allopurinol. These results suggest that SSRIs aggravate NSAID-induced antral lesions, probably via the activation of 5HT(3) receptors, and the mechanism of aggravation may involve the corrosive action of acid/pepsin as well as an impaired antioxidative system.
