Introduction: Polysaccharides have numerous therapeutic values including immunity stimulation, angiotensin converting enzyme inhibition, wound healing, anti-diabetic and cytotoxic activities, in addition to their potent anti-oxidant properties. This work examined the gastroprotective and ulcer healing potential of mucilage fraction isolated from Solenostemma argel (Delile) Hayne (MFA) against ethanol-induced gastric ulcer in rats. Methods: Forty Sprague-Dawley rats were divided into five groups (n=8); normal control (I), ethanol control (II), 20 mg/kg Antodine pretreated rats (III), 100 mg/kg, and 200 mg/kg MFA pretreated rats, respectively (IV & V). All rats in groups II-V received single intragastric dose of ethanol (5 mL/kg) to induce gastric ulcer. Gastric mucosal injuries were assessed by stomach gross examination as well as histopathology, and immunohistochemistry of apoptotic markers. Also, several biochemical parameters including oxidative stress, proinflammatory cytokines, cytoprotective and cell proliferative biomarkers were measured. Results: High-performance liquid chromatography (HPLC) analysis of MFA revealed its composition of glucose, D-fucose and N-acetyl glucosamine as monosaccharaides, in addition to glucuronic and galacturonic acids. The data showed that MFA, 200 mg/kg had potent antioxidant, anti-inflammatory, cytoprotective, cell proliferative, and antiapoptotic activities which were better than Antodine. Conclusion: This study revealed that MFA had significant gastroprotective effects against ethanol-induced gastric injuries and could be a promising adjuvant therapy for ulcer treatment.

Background: Curcumin is claimed as a potent protectant against gastric ulcer (GU) induced by strong necrotizing agents including NSAIDs through its antioxidant, anti-inflammatory and gastroprotective activities. However, it was found to exert opposite effects to either delay ulcer healing or exacerbate ulcer inflammation through some curative mechanisms differently modified by curcumin dosage. Its ability in inhibiting the expression of COX-2 may also delay the healing of NSAIDs-induced GU. Recently, a topical chitosan-curcumin solution has been found to be a safe and potential alternative agent in treating oral ulcer. Therefore, an oral chitosan-curcumin mixture was developed and determined for its efficacy in treating NSAIDs-induced GU in rat. Methods: A chitosan (150 mg)-curcumin (20 mg) mixture with optimal gastric pH was developed. Indomethacin (30 mg/kg) was given orally to the rat and test preparations were administered orally at 5 h later and then every 24 h for two consecutive days. The sum of all gastric ulcerated areas (mm2) for each stomach was used as ulcer index. Gastric pro-inflammatory mediators and cytoprotective factors were determined. Results: An oral administration of a chitosan-curcumin mixture exerted a superior efficacy than curcumin, chitosan or lansoprazole (a standard antiulcer agent) in healing indomethacin-induced GU. It was revealed that the mixture exhibited the highest anti-oxidant, anti-inflammatory and gastric mucus producing activities including the high potency in down-regulating pro-inflammatory COX-2 and iNOS expression but up-regulating cytoprotective COX-1, nNOS and eNOS expression. Conclusion: The present findings indicated the benefit of a chitosan-curcumin mixture as a potential alternative agent in treating NSAIDs-induced gastric ulcer.
