| Abstract | La présente Ligne directrice décrit une procédure in vitro permettant l’identification de produits chimiques (substances et mélanges) ne relevant d’aucune classification pour l’irritation oculaire ou les lésions oculaires graves, conformément au SGH de l’ONU. Un modèle d’épithélium cornéen humain reconstitué (EChR) est utilisé, qui reproduit fidèlement les propriétés histologiques, morphologiques, biochimiques et physiologiques de l’épithélium cornéen humain. Le test évalue le danger potentiel qu’un produit chimique testé présente pour l’œil en se fondant sur sa capacité à provoquer une cytotoxicité sur un modèle tissulaire d’EChR, mesurée avec le test MTT. Les produits chimiques colorés et ceux qui interfèrent avec le MTT peuvent également être testés par procédure HPLC.La viabilité du tissu d’EChR après exposition à un produit chimique testé est déterminée par comparaison avec celle de tissus traités avec la substance servant de témoin négatif (% de viabilité) puis utilisée pour prédire le danger potentiel du produit chimique testé pour les yeux. Les produits chimiques qui ne relèvent d’aucune classification dans le SGH de l’ONU sont ceux qui ne provoquent pas une diminution de la viabilité tissulaire en deçà d’un seuil défini (à savoir, viabilité tissulaire > 60 % pour le classement « sans catégorie » du SGH de l’ONU). |

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.
