| Abstract | Summary form only given. Laser induced human serum Raman spectra of liver cancer are measured. The spectra differences in serum from normal people and liver cancerous people are analyzed. There is obvious difference between the spectrum of liver cancer and that of normal people. For the typical spectrum of normal serum there are three sharp Raman peaks (A at/spl sim/1010cm/sup -1/, at/spl sim/1160cm/sup -1/, C at/spl sim/1525cm/sup -1/) and relative intensity of Raman peak excited by 514.5 nm is higher than that excited by 488.0nm. However, for the Raman spectrum of liver cancerous serum there are no peaks or very weak Raman peaks at the same positions of spectrum and intensity of Raman peak excited by 514.5 nm is lower than that excited by 488.0 nm. Results of more than two hundred case measurements show that clinical diagnostic accuracy is 92.86%. And then, the liver fibrosis is studied applying the technology of LIF. The experiment indicates that there is notable fluorescence difference between the abnormal and normal liver tissue, there is blue shift abnormal tissue in compare with normal liver tissue. These results have important reference values to explore the method of laser spectrum diagnosis. |

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.
