Clinical Applications of Scanning Electron Microscopy in Gastrointestinal Diseases

We considered the role of scanning electron microscopy (SEM) in clinical investigation of different gastrointestinal diseases. The following clinical applications of SEM may be suggested on the basis of our original data and those reported in literature: in peptic ulcer: assessment of the completeness of healing, by observing the mucosal surface architecture of the scars; identification of mucosal changes, namely enterocytic surface membrane alterations, predictive of recurrence; in coeliac disease: early assessment of the response to gluten-free diet and follow-up of the patients by staging the process of mucosal repair in cerebriform, intermediate and villous patterns; in ulcerative and Crohn\u27s colitis: enhancement of the diagnostic sensitivity of perendoscopic biopsy, by detecting differences in surface structure of mucosa surrounding ulcers in both diseases. This is subverted in ulcerative colitis and preserved in Crohn\u27s colitis. Finally the complementary role of SEM in relation to endoscopy and light microscopy is emphasized

The effect of dalargin on growth factors content in experimental ulcerative colitis

The aim of the study was to evaluate the dalargin effect on the content of transforming growth factor-β (TGF-β) and epidermal growth factor (EGF) in the colonic wall in mice with experimental ulcerative coliti

Development And Evaluation Of Colon Targeted Drug Delivery For Mesalamine

The main objective of this study was to formulate mesalamine loaded alginate microspheres for local treatment of ulcerative colitis and optimized batch were then filled in capsules coated with Eudragit S 100. The microspheres were prepared by ionic gelation method. Box Behnken design using design expert software was employed in formulating and optimizing the microspheres. Microspheres were evaluated for particle size, shape and entrapment efficiency. The optimized batch was then filled in capsule coated with Eudragit S100.This encapsulated system released alginate microspheres at colon region in a sustained manner. The drug release of microspheres showed a longer residence time in the colon due to better mucoadhesion properties of sodium ALG. Therefore mesalamine-loaded alginate microspheres enteric coated in capsules can be potential delivery system for local treatment of ulcerative coliti

Nutritional Therapies for Ulcerative Colitis: Literature Review, Chart Review Study, and Future Research

Few clinical studies suggest a significant influence of diet or nutritional supplementation on ulcerative colitis. One reason is that ulcerative colitis, like many chronic diseases, is multifactorial. This article reviews the relevant literature and presents the results of a retrospective chart review study that was done at a complimentary medicine office
