Protective effect of n-3 polyunsaturated fatty acid on primary culture of rat hepatocytes.

Background And Aim: Recently, we reported on the beneficial clinical effects of eicosapentaenoic acid (EPA) in patients with primary biliary cirrhosis (PBC) who were unresponsive to ursodeoxycholic acid (UDCA). In this study we examined the effect of EPA on rat hepatocytes in primary culture.

Methods: Hepatocytes were isolated from rat liver by perfusion of collagenase and cultured with or without EPA.

[Significance of PPI-test in the diagnosis of GERD].

Gastroesophageal reflux disease (GERD) is defined as 'Chronic symptoms or mucosal damage produced by the abnormal reflux of gastric contents into the esophagus'. Reflux esophagitis refers to a subgroup of GERD patients with histopathologically demonstrated characteristic changes in the esophageal mucosa. Besides, GERD includes symptoms without endoscopic findings (endoscopic negative GERD) and extra-esophageal symptoms.
