| Abstract | Mononuclear cells from normal volunteers and from patients with the hyperimmunoglobulin E recurrent infection syndrome (HIE) were cultured for 18 h with and without opsonized, heat-killed Staphylococcus aureus (OS). The supernatants from normal mononuclear cell cultures without OS revealed no inhibitory activity for neutrophil chemotaxis, whereas those from HIE patients revealed the previously reported 61,000-dalton factor. However, when normal cells were cultured with OS, they produced a proteinaceous, 56 degrees C-stable, 30,000- to 45,000-dalton factor which preferentially inhibited neutrophil versus monocyte chemotaxis. When HIE cells were exposed to OS, they produced the same 30,000- to 45,000-dalton factor as normal cells, as well as the 61,000-dalton factor that they produced spontaneously. Assay of 1,000-fold dilutions of supernatants from cultures of normal mononuclear cells with OS revealed a mean production of 7.8 +/- 5.4% inhibition of chemotaxis, whereas assay of 1,000-fold dilutions of supernatants from cultures of HIE mononuclear cells (spontaneously producing the 61,000-dalton factor) with OS revealed a 26.6 +/- 3.6% inhibition (P less than 0.02). The data indicate that in short-term culture both normal and HIE mononuclear cells produce an inhibitor of neutrophil chemotaxis when exposed to particulate heat-killed staphylococci but that HIE cells produce qualitatively and quantitatively more inhibitory activity. |

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.
