| Abstract | The aim of this pilot study was to investigate variability of oxidative stress during sepsis evolution. ICU patients with the diagnosis of septic shock were included. Thiobarbituric-acid reactive substances, total antioxidant capacity, protein carbonyls in plasma, reduced, oxidized glutathione and catalase activity in erythrocyte lysate were assessed in the 1st, 3rd, 5th and 8th day after sepsis appearance. A total of 17 patients were divided in two groups: survivors (n=7) and non-survivors (n=10). APACHE II was 11.5 ± 5.4 and 19.9 ± 4.97 in survivors and non-survivors respectively (p=0.005), while mean age and SOFA score at sepsis diagnosis, were similar between the two groups. GSH levels, catalase activity and protein carbonyls presented significant different course in time between survivors and non-survivors (p<0.05). Catalase activity was significantly higher in survivors (238.8 ± 51.5) than non-survivors (166.4 ± 40.2; p=0.005), while protein carbonyls levels were significantly lower in survivors (0.32 ± 0.09) than non-survivors (0.48 ± 0.16; p=0.036) on the 1st day. Yet, non-survivors exhibited a declining course in GSH levels during time, while GSH levels were maintained in survivors. Conclusively, a longstanding antioxidant deficiency in non-surviving patients was noted. This phenomenon was clearly prominent in patients' erythrocytes. |

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.
