pylori seropositivity, the

optimum cut-off sPGII value was 10.25 microg/L (sensitivity 71.6%, specificity 70.1%). Conclusions:  We demonstrated that the mean values of sPGII in a healthy Chinese population are 7 microg/L and 6 microg/L for males and females, respectively. sPGII significantly selleck chemical increases in diseased and H. pylori-infected stomach, and the best sPGII cut-off value is 8.25 microg/L in the differentiation between patients with healthy and diseased stomach mucosae. Furthermore, Chinese patients with sPGII greater than 10.25 microg/L are at greater risk of various H. pylori-related gastropathies, and are therefore prior candidates for gastro-protection therapy. “
“Background and Aim:  Contemporary medications used in the treatment of gastric ulcers involve

the use of novel mucosal protective drugs. The present study aimed to investigate the gastroprotective effect of ginger extract and polaprezinc in a rat model of acetic selleck inhibitor acid-induced gastric ulcer. Methods:  ‘Kissing’ ulcers were induced in male Sprague-Dawley rats by using 60% acetic acid. Rhizoma Zingiber officinale (ginger) extract (1.5–5 g/kg) or polaprezinc (30 and 60 mg/kg) was orally given to the animals once daily for three consecutive days after ulcer induction. All animals were killed on day 5 by an overdose of ketamine. Results:  Both ginger extract and polaprezinc significantly reduce the gastric ulcer area in a dose-dependent manner, with concomitant attenuation of the elevated activities of xanthine oxidase and myeloperoxidase, as well as malondialdehyde level in the ulcerated mucosa. Nevertheless, only polaprezinc could restore the mucosal glutathione level. Polaprezinc also causes the overexpression of basic fibroblast growth factor, vascular endothelial growth factor

and ornithine decarboxylase, whereas ginger extract only increases the expression of the two growth factors in the gastric mucosa. Furthermore, polaprezinc could consistently downregulate the protein expression of tumor necrosis factor (TNF)-α, interleukin-1β, macrophage Low-density-lipoprotein receptor kinase inflammatory protein-2 and cytokine-induced neutrophil chemoattractant-2α that have been activated in the ulcerated tissues, whereas ginger extract mainly inhibits the expression of the chemokines and to some extent TNF-α. Conclusion:  Ginger extract and polaprezinc both show anti-oxidation that consequently alleviates gastric mucosal damage and promotes ulcer healing, which together serve as effective mucosal protective agents. “
“The liver contains macrophages and myeloid dendritic cells (mDCs) that are critical for the regulation of hepatic inflammation. Most hepatic macrophages and mDCs are derived from monocytes recruited from the blood through poorly understood interactions with hepatic sinusoidal endothelial cells (HSECs). Human CD16+ monocytes are thought to contain the precursor populations for tissue macrophages and mDCs.
