| Abstract | Nonsteroidal anti-inflammatory drugs can cause serious side-effects such as tubulo-interstitial nephritis. Mesalazine (5-ASA, 5-aminosalicylic acid) is used for the treatment of colitis ulcerosa, Crohn disease, and other diseases; it has been found to induce necrosis of both proximal convoluted tubules and renal papillaries. The comparative cytotoxicity of 3-, 4-, and 5- aminosalicylic acid, acetylsalicylic acid (AcSA), and the parent compound salicylic acid (SA) was investigated for the free acids and for their sodium salts. The interaction with endogenous glutathione (GSH) was also investigated. Four established cell lines were used: MDCK, LLC-PK1, NRK as renal cells, and HepG2 as hepatic cells. The free acid compounds were less toxic than their corresponding salts. Acidic 5-ASA was the most toxic of the three isomers in MDCK and LLC-PK1 cells, while NRK and HepG2 were more susceptible to acidic 3-ASA. Addition of NaOH modified the relative toxicity of 3-ASA and 5-ASA. The LLC-PK1 and HepG2 cells were more sensitive to the test chemicals as their salts than were the NRK and MDCK cells. SA and 5-ASA decreased the GSH content in renal cells and increased it in HepG2. GSH depletion with l-buthionine-(S,R)-sulfoximine enhanced the toxicity only for SA in NRK and for 5-ASA and AcSA in HepG2. No correlation between endogenous GSH and the susceptibility of MDCK and LLC-PK1 to the test compounds was observed. The results suggest that no typical nephrotoxic effect occurred. No explanation could be found for the tubulo-interstitial nephritis caused by 5-ASA therapy. |

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.
