Recent progress in drug therapy of ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory bowel disease of unknown etiology. Current common medical treatments for UC are mainly composed of anti-inflammatory and immune-regulatory medications, such as aminosalicylic acid and glucocorticoids. New biological agents as well as probiotics have also emerged as recommended drugs for clinical treatment of UC. The advances in research and the rapid development of pharmaceutical technology have resulted in new progress in treatments for UC. This article will review recent progress in drug therapy of ulcerative colitis.

Murine model of dextran sodium sulfate induced ulcerative colitis

Ulcerative colitis (UC) is an idiopathic, chronic inflammatory disorder of the colonic mucosa, and its etiology remains unclear. Animal models are commonly used to study UC, including the murine model of colitis induced with dextran sulfate sodium (DSS). The murine model of DSS-induced colitis is well appreciated and widely used because of its simplicity, cheapness and high success rate. DSS-induced colitis has many similarities to human UC in location, clinical and histological features. In view of its indispensable position in the study of UC, we provide a brief overview of the animal model of DSS-induced colitis in terms of its features, modelling methods, pathogenesis and influencing factors.
