Quantitative index imaging of coculture cells by scanning focused refractive index microscopy.

We report the quantitative refractive index (RI) imaging of cocultured cells in their living environment by scanning focused refractive index microscopy (SFRIM). Mouse microglial cells and synovial cells are cocultured on the top surface of a trapezoid prism. The RI imaging of living cells is obtained in a reflection-type method.

Measurement of complex refractive index of turbid media by scanning focused refractive index.

We present the application of scanning focused refractive index microscopy in the complex refractive index measurement of turbid media. An extra standard scattering layer is placed in front of the detector to perform scattering transformation on the reflected light. The principle of the scattering transformation is elaborated theoretically.

[Analysis the relation of adults HBV vicinal failure and T cell subset, HLA-DR rang gene phenotype].

Objective: To study and explore the relativity of adults HBV vicinal failure and HLA-DR, T cell subset, trace viruses infection. To accumulate date for formulating preventing adult HBV infection prophylactic-therapeutic measures.

Methods: Select 20 adults randomly who had vaccinated with 10 microgYDV and produced anti-HBS successfully, and another 20 hadn't produced anti-HBs to form two groups-defeated group and contral group.
