BACKGROUND AND AIMS The effects of dextran sulphate sodium (DSS) on mouse intestinal epithelial cells and intraepithelial lymphocytes were analysed to investigate the mechanism by which DSS induces colitis and tumours in mice. Cytotoxicity of DSS towards intestinal epithelial cells and intestinal intraepithelial lymphocyte hybridomas or fresh intestinal intraepithelial lymphocytes seems to have...

Calculus Bovis Sativus (CBS) is a commonly used traditional Chinese medicine, which has been reported to exhibit antispasmodic, fever-reducing, anti-inflammatory, and gallbladder-repairing effects. The present study aims to investigate the protective effect of CBS on dextran sulphate sodium- (DSS-) induced ulcerative colitis (UC) in mice. C57BL/6 male mice were exposed to 5% DSS in drinking wat...

Abstract Acanthus ilicifolius var. xiamenensis (Acanthaceae), a mangrove found in southeastern China, is an herb with strong antiinflammatory property. Phytochemical study of the showed that plant has high content phenylethanol glycoside acteoside (AC). In this research, anti-inflammatory activity on dextran sodium sulphate (DSS)-mediated mouse ulcerative colitis model were studied. For DSS- me...

AIM To assess the short-term efficacy of hypotonic 0.18% sodium hyaluronate in patients with evaporative tear-sufficient dry eye due to lipid tear deficiency (LTD). METHODS This was a randomised, double-blind, controlled, exploratory study. A total of 10 patients with dry eye due to LTD were treated as follows: one drop of hypotonic 0.18% sodium hyaluronate in one eye and one drop of isotonic...

The selectin-mediated rolling of leukocytes along the endothelial cells is a prerequisite step followed by firm adhesion and extravasation into the inflamed tissue. This initial contact can be suppressed by sulphated polysaccharides. We have studied the effect of sulphated polysaccharides on the ultimate polymorphonuclear leukocyte (PMN) recruitment and plasma leakage in rabbit skin in response...
