Human Factor XII is known to undergo autoactivation in the presence of dextran sulphate of Mr 500000. We have now studied the dependence of this reaction on the Mr of the dextran sulphate by using fractions resolved by gel filtration. We have found that autoactivation can be induced by dextran sulphate fractions with Mr as-low as 3000, and there is a marked dependence of the rate constant of au...
In this study, long term dextran sulphate sodium administration was studied to ascertain whether colorectal carcinoma could be produced in patients with long standing ulcerative colitis. Simultaneously, changes in the intestinal microflora were analysed. Low grade to high grade dysplasia was seen in three of the five hamsters treated with 1% dextran sulphate sodium solution for 100 days, while ...
Background & Aims: Leptin is overproduced in gastrointestinal mucosa during inflammatory processes, suggesting that mucosal cells represent sources of secreted leptin active in the lumen. The effects of leptin, acting apically from colonic epithelial cells, were analysed on dextran sulphate sodium-induced colonic inflammation in rats. Methods: We determined the effects of intracolonic leptin on...
Ulcerative colitis (UC) is a chronic, nonspecific, inflammatory disease for which an effective treatment is lacking. Our previous study found that Qingchang Wenzhong Decoction (QCWZD) can significantly improve the clinical symptoms of UC and ameliorate dextran sulphate sodium- (DSS-) induced ulcerative colitis in rats by downregulating the IP10/CXCR3 axis-mediated inflammatory response. The pur...
Inflammatory bowel disease is an idiopathic autoimmune disorder that is mainly divided into ulcerative colitis and Crohn's disease. Probiotics are known for their beneficial effect and used as a treatment option in different gastrointestinal problems. The aim of our study was to find suitable bacterial vectors for gene therapy of inflammatory bowel disease. Salmonella enterica serovar Typhimuri...
