| Abstract | Cette Ligne directrice décrit un essai in vitro qui peut être utilisé afin d’identifier des produits hydrosolubles corrosifs et irritants sévères de l’œil de la Catégorie 1 du Système général harmonisé de classification et d’étiquetage (SGH) de l’ONU. L’essai est réalisé dans un puits où une monocouche confluente de cellules Madin-Darby Canine Kidney (MDCK) sert de séparation entre deux chambres. Il utilise la fluorescéine comme marqueur. La substance d’essai peut détériorer les jonctions des cellules MDCK et donc d’accroître la perméabilité de la monocouche. De ce fait, la fluorescéine passe à travers la monocouche et la fuite de fluorescéine (FL) augmente. La fuite est calculée sous forme d’un pourcentage établi par référence à un contrôle à blanc et à un contrôle de fuite maximum. La concentration de la substance d’essai provoquant 20% de FL (FL20, en mg/mL) est calculée et utilisée comme modèle de prédiction pour l’identification des produits corrosifs et irritants sévères de l’œil. La valeur limite de FL20 permettant de classer les produits chimiques hydrosolubles comme corrosifs/irritants sévères de l’œil est ≤ 100mg/mL. La méthode d’essai par fuite de fluorescéine fait partie de stratégies d’essai étapes. |

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.
