Pretreatment with the butanol extract of the water fraction of Phyllanthus emblica fruits at the dose of 100 mg/kg body-weight, orally administered to rats for 10 consecutive days, was found to enhance secretion of gastric mucus and hexosamine (PB0.001) in the indomethacin induced ulceration of rats. The morphological observations also supported a protective effect of the stomach wall from lesion. The indomethacin treatment of the premedicated animals with the drug hardly affected either the malondialdehyde (MDA) or superoxide dismutase (SOD) level in gastric tissue while the ulcerative agent itself significantly enhanced both the levels. An antioxidant property appears to be predominantly responsible for this cytoprotective action of the drug.
Inhibition of experimental gastric lesion and inflammation by Phyllanthus amarus extract
Journal of Ethnopharmacology, 2003
Methanolic extract of Phyllanthus amarus Shum & Thonn (Euphorbiaceae) 50, 200, and 1000 mg/kg body weight significantly inhibited gastric lesions, induced by intragastric administration of absolute ethanol (8 ml/kg). Mortality, increased stomach weight, ulcer index, and intraluminal bleeding were reduced significantly by Phyllanthus amarus. Biochemical analysis indicated that reduced glutathione (GSH) of gastric mucosa produced by ethanol administration was significantly elevated by treatment with Phyllanthus amarus extract. Aqueous and methanol extracts of Phyllanthus amarus produced an inhibition of rat paw edema up to 42% compared to control in 3 h and continued up to 8 h. Anti-oxidant activity of the extract as well as presence of tannins in the extract may be responsible for these observed activities.

Gloriosa superba plant is well documented traditionally in Ayurvedic system of medicine and is used in treating many diseases. The present study was undertaken to evaluate the gastroprotective effect of Gloriosa superba tuber extract (GSTE) on rats at the dose of 110mg/kg body weight. Administration of test drug (110mg/kg) reduced gastric lesions as compared to Indomethacin (25 mg/kg) treated group. In vivo antioxidant levels were also evaluated. It was observed that administration of Indomethacin caused significant decrease in levels of SOD, GSH, GSHPx and increase in level of LPO. But reverse trend was seen in rats pre-treated with test drug, that is increase in levels of SOD, GSH, GSHPx and decrease in level of LPO. The results suggest that the gastroprotective activity of methanolic extract of Gloriosa superba tuber can be contributed to its constituents and antioxidant potential.

Phyllanthus niruri L. belongs to the Euphorbiaceae, and is known by the common name of ‘stonebreaker’ in Brazil. Some species within the Phyllanthus genus are widely used in traditional medicine to counteract different types of anti-inflammatory diseases. Objectives In this study, the preventive intestinal anti-inflammatory activity of spray-dried extract of P. niruri (SDEPn) was tested in the model of acetic acid (10%)-induced ulcerative colitis in the rat. Methods Colitis animals were given orally at doses 25, 100 and 200 mg/kg. Colons tissue was analysed by macroscopic score, by histopathology score, by the immunohistochemical examination of tumour necrosis factor alpha, p53 and interferon gamma; by spectroscopic ultraviolet-visible spectrophotometry (UV/VIS) analysis of the levels of myeloperoxidase, malonaldehyde and total glutathione. Key Findings/Result Pretreatment of the extract to colitic rats significantly attenuated colonic macroscopic damage induced by acetic acid (P &l...

Recently, an alternative disease treatment approach is the research of medicaments from traditional medicine. Plants with anti-oxidant capabilities are used as herbal treatments for ulcer diseases. Medicinal/herbal extracts containing phytoconstituents have significant anti-ulcer activities in in vivo experiments on animal models, compared to reference drugs. The current study aims to inspect gastro-protective as well as in vitro and in vivo anti-oxidant potential of Althaea officinalis and Solanum nigrum extracts on pyloric-ligation/indomethacin-induced gastric-ulceration in rats. Rats were divided into six groups: normal control, gastric ulcer control, two standard pretreatment groups receiving omeprazole and misoprostol, and two test pretreatment groups receiving Althaea officinalis and Solanum nigrum. Pretreatments were administrated orally for 14 days. On the 15th day, animals, excluding the normal control group, were exposed to pyloric-ligation followed by indomethacin injection. After four hours, the rat's stomachs were removed and gastric juice and blood samples were collected. Pyloric-ligation/indomethacin administration caused considerable elevation in ulcer number, ulcer index, acid and pepsin productivity, aggressive factors, and gastric mucosal lipid-peroxide contents. Moreover, reduction in titratable acidity, gastric mucosal nitric-oxide, anti-oxidant contents, and protective factors accompanied gastric-ulceration. Additionally, elevation in pro-inflammatory cytokines content and reduction in cystathionine-β-synthase and heme-oxygenase-1 expression was witnessed. Omeprazole, misoprostol, Althaea officinalis, and Solanum nigrum pretreatments fixed blood and tissue biomarkers, thereby protecting them from pyloric-ligation/indomethacin-induced gastric-ulceration in rats, which is hopeful for clinical examinations.

The preventive effect of Nigella sativa seed on gastric ulcer induced by indomethacin in rat
Journal of Herbmed Pharmacology
Introduction: Nonsteroidal anti-inflammatory drugs (NSAIDs) are considered as one of the most administrated groups of medications worldwide. Due to the role of NSAIDs in inducing gastric ulceration, their clinical applications are still challenging. Nigella sativa seed is widely used as an herbal medication against gastrointestinal complications. The present experiment was carried out to investigate the impact of N. sativa seed hydro-alcoholic extract on gastric ulcer induced by indomethacin (IND) and to evaluate its possible mechanisms in rat. Methods: This study was performed on 48 male Wistar rats. Acute gastric ulceration was induced by IND (35 mg/kg). N. sativa seed extract (100, 200, 400 mg/kg) and ranitidine (50 mg/kg) were administered orally for five days before the induction ulcer. Ulcer index, gastric acid secretion, gastric mucus content, glutathione (GSH), malondialdehyde (MDA), total hexose, gastric juice protein content were determined on the fifth day. Results: The u...

The medicinal plants signify a massive basin of potential phytoconstituents that could be valuable as a substitute to allopathic drugs or considered as an analogue in drug development. Phyllanthus niruri L. (Euphorbiaceae) is generally used in traditional medicine to treat ulcer and inflammation. In this project we investigated the methanolic extract of leaves of Phyllanthus niruri for anti-inflammatory and anti-ulcer activity. The anti-inflammatory activity of methanol extract of Phyllanthus niruri leaves was evaluated at the doses of 100, 200 and 400 mg/kg, p.o. while using ibuprofen (20 mg/kg, p.o) as the standard drug. The animals used were Swiss albino rats. Inflammation was induced by injecting 0.1 ml carrageenan (1% w/v) into the left hind paw. Paw tissues from the different groups were examined for inflammatory cell infiltration. On the other hand, antiulcer activity of methanolic extract of P. niruri leaves at the doses of 100, 200 and 400 mg/kg, p.o. were examined against ...

The present work is an attempt to elucidate the anti-ulcer activity of indole-3-carbinol as antioxidant alone or in combination with omeprazole a proton pump inhibitor to diminish the effects of induced gastric ulcer by aspirin. It also emphasizes on the role of omeprazole and indole-3-carbinol on the extent of healing gastric ulcer. To attain this goal, a total number of 96 male albino rats were presently investigated. It involved different aspects of study namely physiological, biochemical, histological, histochemical and immunohistochemical changes on stomach tissues. The present findings were then discussed in view of the relevant literature available in similar fields of study. This study showed that the use of indole -3 - carbinol as antioxidant with omeprazole in the treatment of gastric ulcers in rats, may help in healing gastric ulcers and improvement of all different parameters. Thus, suggestions for further studies using indole -3 - carbinol as anticancer and antioxidant agent either administrated directly from vegetables of the Cruciferae family or using this active ingredient indole-3 - carbinol in drug preparation of anti-inflammatory drugs.

A peptic ulcer is one of the more severe diseases and most classic treatment protocol produce adverse drug reactions. Therefore, this study aimed to examine the therapeutic effects of two natural extracts, namely Pomegranate and Ginger, on indomethacin-induced gastric ulcer in rats. Animals were divided into five groups; 1. Normal control group, 2. An ulcer control group Indomethacin (0.3 mg /rats), 3. Omeprazole (3 mg /rats), a4. Pomegranate (40 mg /rats), 5. Ginger (20 mg /rats). The ulcers were induced made from groups 2 - 5 by oral administration of Indomethacin. Rats subjected to indomethacin administration showed significant ulceration in the glandular area of their stomachs compared to normal control rats. In addition, significant elevations S.GPT, S.GOT, S. creatinine and S. Urea (P< 0.05) were observed. Alternatively, pretreatment with pomegranate and ginger significantly corrected macroscopic and biochemical parameters. These results demonstrate that administration of ...
