| Abstract | Erythrocyte aggregation is a useful indicator of the physico-chemical characteristics of erythrocytes and the suspending medium. Increased erythrocyte aggregation is the measure of blood flow abnormality and hence of cardiovascular complications. Erythrocyte aggregation has been shown to increase in many pathological conditions like cardiovascular and infectious diseases and cancer. Therefore, the measurement of erythrocyte aggregation is an important parameter in clinical and rheological laboratories. Many methods are available for the quantification of erythrocyte aggregation. These methods include the simple microscopic observation modern laser based instruments and advanced rheoscopic measurements. The present paper discusses a computerized system developed for the quantification of erythrocyte aggregation. This method is based on continuous measurement of laser light scattering through erythrocyte suspension. From the light profile, different aggregation parameters are computed on-line. Erythrocyte aggregation is quantified by different time and rate parameters automatically interpreted by the system. The sensitivity of the system has been studied by making alterations to erythrocytes and the suspending medium. Erythrocyte alterations are performed by diamide solution and suspending medium with dextran solutions. Results show a significant variation in the aggregation of modified samples as compared with controls (p<0.05-0.0005). Quantification by laser scattering is substantiated with results obtained from microphotographic and scanning electron microscopic studies. |

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.
