| Abstract | In order to analyze the velocity change of lymphocyte flow in microcirculation in vivo, a spatial filtering velocimeter was applied to velocity measurements in the microscopy region. The spatial filter was constructed with an optical fiber array and the moving lymphocyte image was formed on it through a microscope. The frequency of the output signal was related to the lymphocyte velocity. The lymphocyte flow velocity was periodically changed and backward flow was often observed. An image of the lymph vessel was also recorded, and the relationship between the velocity change of lymphocyte flow and the contraction of the lymph vessel was considered. The optical fiber array spatial filtering velocimeter was applied to measurements of the lymph flow velocity in rat mesentery. The periodic time of the velocity change of the lymph flow and of the diameter change of the lymph vessel were about 2 approximately 3 seconds and it was much longer than that of the cardiac action. |

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.
