Commiphora myrrh Supplementation Protects and Cures Ethanol-Induced Oxidative Alterations of Gastric Ulceration in Rats

Gastric ulceration is a multifactorial disease defined as a defect in the gastric wall that extends through the muscularis mucosae into the deeper layers of the wall. The most common cause of gastric ulceration is alcohol consumption. In the current study, rats were gavaged by ethanol to investigate the protective (before ethanol) and curative (after ethanol) ability of Commiphora myrrh (myrrh) oil and extract against gastric ulcer oxidative alterations induced by ethanol. Myrrh significantly improved ulcer index, histomorphology, and periodic acid Schiff (PAS) impaired by ethanol. In addition, myrrh improved the antioxidant potential of gastric mucosa through enhancement of nuclear factor related to erythroid 2 (Nrf2), total glutathione (GSH), reduced GSH, and oxidized glutathione (GSSG), along with significant reduction in malondialdehyde (MDA) levels. Amelioration of gastric oxidative stress by myrrh enables gastric mucosa to counteract the ethanol’s inflammatory and apoptotic processes leading to improved gastric proliferation and healing. Interestingly, myrrh extract showed better protective and curative effects than myrrh oil against gastric ulceration.

Effect of Trianthema triquetra Rottl. ex Willed (Aizoaceae) on ethanol-induced gastric ulcers in experimental rats

Trianthema triquetra Rottl. Ex.Willed (T. triquetra) is a medicinal plant that belongs to the family Aizoaceae. The plant has been used traditionally as fodder, as a remedy for chronic ulcer, fever, and healing wounds. Therefore, the present study was intended to investigate the anti-ulcer ability of different fractions of T. triquetra to verify its folklore use in ulcer cure. Acute oral toxicity of all the fractions of T. triquetra was evaluated at a dose of 2g/kg b.wt. Anti-ulcer potential of nbutanol (TTB), chloroform (TTC), ethyl acetate (TTEA) and aqueous (TTA) fraction of crude methanolic extract of T. triquetra was assessed by using ethanol- induced gastric ulcer model in rats. Omeprazole at a dose of 20 mg/kg b.wt. was used as standard drug. After 1 hour of administration of all the fractions of T. triquetra, at a dosage of 300mg/kg b.wt., the gastric ulcer was induced in all animals by administering absolute ethanol (1mL/animal) orally except normal control group. After an hour, all the rats were sacrificed. Ulcer index, % age of ulcer inhibition, gastric pH, gastric volume, total acidity, gastric wall protein, gastric wall mucus and histopathology of the stomach wall of rats were assessed. All fractions of T. triquetra showed a substantial decrease in ulcer index and improvement in percentage inhibition compared to the disease control group. There was a rise in the amount of gastric wall mucus content, total protein content, gastric pH and a decrease in gastric volume and total acidity. Histopathological studies showed severe mucosal injury, leucocyte infiltration and edema in the disease control group compared to omeprazole and plant fractions treated animal groups. The present work encourages the conventional use of T. triquetra in the cure of ulcers.

Gastroprotection and mucus stimulation by vitamin D3 in pyloric ligation and Indomethacin-induced gastric ulcers rats models

The effect of vitamin D3 (VD3) on gastric ulcers was investigated by evaluating ulcer index, biochemical aggressive, and protective factors. Rats were divided into 4 groups; untreated indomethacin ulcer, VD3 pre-treated + indomethacin ulcer, untreated pyloric-ligation ulcer and VD3 pre-treated + pyloric-ligation ulcer. Treatment with VD3 (400 IU/kg intramuscular) was done daily for 6 days and an hour before ulcers induction. Four hours post-induction, the blood sample was obtained for the determinations of 1,25-dihydroxy vitamin D (1,25-DHCC), Parathyroid Hormone (PTH), and Calcium (Ca). Laparotomy was performed and the stomach was harvested for gastric acidity, ulcer index, and biochemical evaluations. The data were analyzed using statistical tools and the “student t-test” was performed at p<0.05. VD3 pre-treatmment caused an increase in serum levels of 1,25-DHCC, has no significant effect on PTH and Ca levels but decreased gastric acidity and ulcer index (p<0.05) with protective ratios of 42.11% and 60.00% against indomethacin and pyloric-ligation ulcers respectively. Pretreatment resulted in decreased gastric MDA, increased gastric protein, mucin, and nitric oxide levels. Gastric protection by VD3 was through oxidative stress inhibition and stimulation of mucus and blood flow against indomethacin and pyloric ligation gastric damage.

Agarwood Alcohol Extract Protects against Gastric Ulcer by Inhibiting Oxidation and Inflammation

Background. Agarwood has been used for centuries, especially for treatment of gastrointestinal diseases. Earlier studies of our laboratory suggested that agarwood alcohol extracts (AAEs) provided gastric mucosal protection. This study aims to investigate the ameliorative effect of AAEs on ethanol-induced gastric ulcers and its mechanism. Methods. Mice were given agarwood induced by the whole-tree agarwood-inducing technique alcohol extract (WTAAE, 0.71, 1.42, and 2.84 g/kg), wild agarwood induced by axe wounds alcohol extract (WAAE, 2.84 g/kg), and burning-chisel-drilling agarwood alcohol extract (FBAAE, 2.84 g/kg) orally, respectively. After 7 days’ pretreatment with AAEs, the gastric ulcers were induced by absolute ethanol. The ulcer index, gastric histopathology, biochemical parameters, and inflammatory proteins were evaluated. Results. Pharmacological results showed AAEs (1.42 and 2.84 g/kg) reduced the gastric occurrence and ulcer inhibition rates up to more than 60%. AAEs decreased the level of nitric oxide (NO) and increased glutathione (GSH) and superoxide dismutase (SOD) levels. Besides, AAEs decreased the levels of interleukin-1β (IL-1β) and interleukin-6 (IL-6), but the interleukin-10 (IL-10) was upregulated. The expressions of nuclear factor kappa B (NF-κB) and phosphorylated protein 38 (p-P38) were inhibited. The effect of WTAAE was better than that of FBAAE and similar to that of WAAE at the dose of 2.84 g/kg. Conclusions. These results demonstrate that agarwood alleviates the occurrence and development of gastric ulcers via inhibiting oxidation and inflammation.

Phytochemical and Pharmacological Evaluation of Annona reticulate

Annona reticulate (AR) is indigenous to the tropical areas of India and worldwide. The use of plant as remedy for diarrhea and ulcer is well documented in Ayurvedic system of medicine. However, pharmacological evidence does not exist to substantiate its therapeutic efficacy for the same. The aim was to investigate the antiulcer and anti-diarrheal activity of methanolic (ME) and aqueous extracts (AE) of A. reticulate in animal model. The antiulcer activity of extracts was investigated using ethanol and pylorus ligation-induced ulcer. The anti-diarrheal activity of MEAR and AEAR extracts was evaluated by castor oil induced diarrhea and gastro intestinal motility using parameters such as onset of diarrhea, number of wet stools, total number of stool and weight of total number of stools. The antiulcer activity of the extracts was confirmed by a reduction in ulcer index along with the decrease in gastric volume, total acidity, and an increase in pH of gastric content in both the models. A. reticulate extracts were more efficacious in reducing number of total stools in both the models of diarrhea and showed a dose-dependent antidiarrheal effect. The obtained results have established a pharmacological evidence for the folkloric use of the A. reticulate as antiulcer and antidiarrhoeal agent.

Antiulcerogenic effect of Methanolic Root Extract of Berberis lycium Linn by Pylorus ligation and Ethanol induced Ulceration

Background: Gastric ulcer is one of the most prevalent gastrointestinal disorders, which affects approximately 5-10% of people during their life. In recent years, abundant work has been carried out on herbal medicine to clarify their potential efficacy in gastric ulcer prevention or management. The present study was carried out to evaluate the antiulcer activity of the methanolic root extract of Berberis lycium in albino rats. Method: The methanolic root extract of Berberis lycium was prepared by hot extraction method. Anti-ulcer activity was evaluated and method employed was pylorus ligation and ethanol induced in albino rats. Preliminary methanolic extract of Berberis lycium was subjected to the acute oral toxicity study according to the OECD guideline no. 425. Animals were divided into four groups of six animals each. The animals of Group I served as normal control (vehicle) which received distilled water. Group II and III received 250 mg/kg and 500 mg/kg of methanolic root extract, respectively. In pylorus ligation induced ulcer model, various parameters were studied viz. gastric volume, pH, total acidity, free acidity, and ulcer index. Ulcer index and percentage inhibition of ulceration was determined for ethanol induced ulcer model. Group IV received Ranitidine at 50 mg/kg was used as the standard drug. Pretreatment of methanol root extract of Berberis lycium showed significant (P˂0.05) decrease in the gastric volume, total acidity and free acidity. However, pH of the gastric juice was significantly increased only at higher dose 500 mg/kg. It showed also significant (P˂0.05) decrease in number of ulcers and ulcer score index in pylorus ligation and ethanol induced ulceration models. Results: The methanol root extract of Berberis lycium showed a significant reduction in the total acidity, free acidity and acid volume. The efficacy of plant extract at high dose was comparable with the standard drug Ranitidine. Conclusion: Our study results support the ethnomedical use of root of Berberis lycium. Keywords: Antiulcer activity, Berberis lycium, Pylorus ligation, Ranitidine, Ulcer Index.
