| Abstract | Early diagnosis of acute mesenteric ischemia (AMI) remains very difficult, partly due to the fact that useful markers of early small bowel ischemia have not yet been identified. Thus, in this study, we aimed to evaluate the levels of serum intracellular enzymes in the tissues and organs in a controlled animal model of mesenteric intestinal ischemia. Forty-eight New Zealand rabbits were divided into 4 groups including the control, artery ligation, vein ligation, and both artery and vein ligation groups. Plasma samples were obtained at 0-, 1-, 3-, 6- and 9-h time-points and enzyme levels were determined. The bowel color and vitality were observed at the same time. The bowel showed an appearance of infarction after a period of ischemia in the animals. Six and 9 h after superior mesenteric artery ischemia, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels increased significantly. However, after 3 h of superior mesenteric venous (SMV) ligation, γ-glutamyl transpeptidase levels in the blood were considerably higher compared to the control group. Six hours after SMV ischemia, ALT, AST, alkaline phosphatase and lactate dehydrogenase levels were significantly elevated compared to those pre-ligation. Serum enzyme levels during intestinal ischemia are not able to provide sufficient information as regards the extent and reversibility of intestinal ischemia, although, they may be able to reflect the presence of injury. |

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.
