Erythema multiforme (EM) is a muco-cutaneous disorders characterized by blisters and subsequent ulcerations with varying degrees of severity. Although the exact etio-pathogenesis erythema not known, it considered to be an immune-mediated disorder which may develop following infections or drug exposure. We report case administration Ceftriaxone in adult male. The patient developed mucosal bullae...

This study was performed to evaluate the protective effect and safety of Oryeongsan water extract (OSWE) on ethanol-induced acute gastric mucosal injury and an acute toxicity study in rats. Acute gastric lesions were induced via intragastric oral administration of absolute ethanol at a dose of 5 mL/kg. OSWE (100 and 200 mg/kg) was administered to rats 2 h prior to the oral administration of abs...

Capsaicin, the pungent ingredient of chilli, is gastroprotective against experimental gastric injury when given intragastrically. Epidemiological and clinical data suggest that chilli ingestion may have a beneficial effect on human peptic ulcer disease. This study showed a gastroprotective effect of intragastric capsaicin, in doses of 2 and 5 mg, on ethanol induced gastric mucosal injury using ...

BACKGROUND The positive effects of ozone therapy have been described in many gastrointestinal disorders. The mechanisms of this positive effect of ozone therapy are poorly understood. The purpose of the present study was to investigate whether the use of ozone may potentiate the gut intestinal mucosal homeostasis in a rat model. METHODS Adult rats weighing 250-280 g were randomly assigned to ...

Patients with type 2 diabetes mellitus are known to have an increased risk of colorectal neoplasia. Dipeptidyl peptidase-4 (DPP-4) inhibitors have been used as a new therapeutic tool for type 2 diabetes. Since the substrates for DPP-4 include intestinotrophic hormones and chemokines such as GLP-2 and stromal cell-derived factor-1 (SDF-1), which are associated with tumor progression, DPP-4 inhib...

Autoantigen-specific immunological tolerance represents a central objective for prevention of type 1 diabetes (T1D). Previous studies demonstrated mucosal antigen administration results in expansion of Foxp3+ and LAP+ regulatory T cells (Tregs), suggesting oral delivery of self-antigens might represent an effective means for modulating autoimmune disease. Early preclinical experiments using the...

BACKGROUND Sulphydryl compounds and nitric oxide are essential in maintaining gastric mucosal integrity. AIMS To characterise the gastric damage induced by a sulphydryl blocker, to evaluate the role of nitric oxide in its pathogenesis, and to reveal its possible prevention by scavenging of free radicals. METHODS Gastritis was induced in rats by addition of iodoacetamide (0.1%) to the drinki...

The roles of active oxygen, lipid peroxidation, and the antioxidative defence mechanism in gastric mucosal injury induced by treatment with indomethacin in rats were investigated. The total area of gastric erosions and concentration of lipid peroxides in the gastric mucosa increased with time after administration of indomethacin (20 mg/kg, orally). The alpha-tocopherol:total cholesterol ratio i...

This is an editorial comment on a recent publication reporting an increased rate of pyogenic liver abscesses (PLAs) after upper gastrointestinal panendoscopy. Its aim is to critically highlight the findings, limitations and potential clinical implications of this study. Issues of the mucosal barrier, the microbial flora, administration of antibiotics and underlying diseases are discussed. The p...

The purpose of this randomized, controlled, blinded, crossover study was to determine the effects of orally administered Yunnan Baiyao (100 mg/kg body weight) on tests of coagulation in dogs. Buccal mucosal bleeding time, prothrombin time, activated partial thromboplastin time, clotting parameters obtained from thromboelastography, and indices of platelet activation were determined before and a...
