| Abstract | Vehicle exhaust from traffic is a widespread air pollutant. The use of 3-wheel auto-rickshaws powered by a 2-stroke engine is widespread in south Asia; exhaust from these vehicles may cause different types of toxicities resulting in different pathologies. The aim of this study was to explore the association between exposure to 2-stroke auto-rickshaw smoke solution (2SARSS) and wound healing. The in vivo model of wound healing was customized to evaluate different stages of wound healing: dermal matrix regeneration, re-epithelialization, and neovascularization. A total of 72 adult mice were divided into 8 groups and exposed to 2SARSS for 12 days. A highly significant reduction (p<0.001) in wound closure was observed among all 2SARSS-treated groups at day 8 post-wounding. Histological examination revealed a significant delay in the outcome of re-epithelialization, dermal matrix regeneration, and maturation of collagen bundles among all 2SARSS-exposed wounds. Delayed activation of neovascularization was seen in the 2SARSS-treated groups at day 12 post-wounding. The Abbot curve, angular spectrum, and several other 3D surface parameters of reverse wound topographies revealed a highly significant reduction (p<0.001) in angiogenesis. These results demonstrate that application of 2SARSS causes a substantial delay in the progression of angiogenesis, resulting in delayed onset of wound healing. These observations validate the damaging effects of 2SARSS on wound healing. Thus, people who are directly or indirectly exposed to this toxic exhaust are expected to have delayed wound healing, which could result in chronic wounds. |

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.
