| Abstract | To examine the effects of three types of resistant starch (RS) on intestinal metabolites, structure and their gastric injury preventive activities, Sprague-Dawley mice were fed diet containing 15% RS for 4 weeks. Response relationships among three types of RS (RS2, RS3, and RS4) food intake, body weight gain, food efficiency, wet weight of cecum (with or not with contents), pH, ammonia production, and short-chain fatty acids (SCFAs) concentration of cecal contents as well as intestinal structure were investigated. All three types of RS had effects on food intake, weight control, lowering of pH, ammonia production in cecal contents, increasing the wet weight of cecum (with or without contents), changes in SCFAs concentration of cecal contents, and physiological structure of small intestine and cecum compared to the control group (common starch-fed rats). RS3 group showed minimum weight gain and food efficiency, compared to both the control group and the other two types of RS diet. RS3 group showed more significant lowering of pH, ammonia production, and SCFAs of cecal contents. In addition, all three types of RS shortened villous height, and muscle and mucosal thickening in small intestine, resulting in significantly decreased villous height and mucosal thickness, whereas significantly increased muscle thickness in the cecum. However, they did not cause detectable pathological changes in the small intestine and cecum. Animal model was also used to check its gastric ulcer preventive effects. The gastric ulcer level was significantly down-regulated by RS3, demonstrating its anti-inflammatory properties. RS3 reduced the levels of serum proinflammatory cytokines of IL-6, IL-12, TNF-α, and IFN-Γ compared to RS2 and RS4. RS3 increased the somatostatin (SS) and vasoactive intestinal peptide (VIP), decreased the motillin (MOT) and substance P (SP) serum levels. These results suggest that RS3 shows the best gastric ulcer preventive effect. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
