Vibrio fluvialis is a Gram-negative, oxidase-producing, halophilic bacterium that, as a pathogen, has been implicated mainly as a cause of gastroenteritis. We describe a case of V. fluvialis peritonitis after a traffic accident that is, to our knowledge, the 1st report of non-continuous ambulatory peritoneal dialysis-related acute peritonitis caused by this organism.

This study was designed to compare the rates of QOUH achievement in rat gastric ulcer model between acid suppressant treated group and gastroprotectant treated group accompanied with elucidations of molecular mechanisms. Serosal injection of acetic acids for generating gastric ulcer and intraperitoneal (ip) injection of recombinant interleukin 1-beta (IL-1beta) for recurring healed ulcer was done in SD rats.

Methods: Sprague-Dawley rats received 4 g/kg body weight (BW) of absolute ethanol intragastrically, which produced visible hemorrhagic gastric lesions 60 min later.
Results: In this animal setting, the pretreatment of Artemisia extracts (30 or 100 mg/kg BW), 1 h before ethanol administration, significantly attenuated the source of gastric injury, which was assessed with gross and microscopic analysis (P < 0.
