| Abstract | Pulmonary silicosis is an irreversible and untreatable disease that is characterized by interstitial lesions and perpetual fibrosis in the lungs. This study was performed to determine whether mesenchymal stem cells (MSCs) and hepatocyte growth factor (HGF) could exhibit therapeutic effects on human silicosis. This non-randomized uncontrolled trial comprised four patients with pulmonary silicosis who had developed lung fibrosis and received autologous bone marrow MSCs previously transfected by a vector containing human HGF cDNA (MSCs/HGF). MSCs/HGF were intravenously administered weekly for three consecutive weeks at a dose of 2 x 10(6) cells/kg. Pulmonary function, high kilo-voltage chest X-ray radiography, computed tomography (CT) scan, and peripheral blood lymphocyte subset and serum IgG concentrations were evaluated after cell therapy. The treatment was found to be generally safe. Symptoms such as cough and chest distress gradually ameliorated at six months post-therapy, accompanied by the significant improvement of pulmonary function. The ratios of the peripheral CD4- and CD8- positive cell concentrations were increased (P < 0.05). Furthermore, the serum IgG levels in these patients were decreased and reached the normal range (P < 0.05). CT scans showed partial absorption of the nodular and reticulonodular lesions in the lungs during follow-up of at least 12 months. The effectiveness of this novel regimen observed in these patients suggests that a placebo-controlled clinical trial needs to be developed. This study carries trial registration No. NCT01977131 (ClinicalTrials.gov). |

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.
