Times Cited Count：0 Percentile：0.01(Nuclear Science & Technology)Several unexplored physics issues will be studied in burning plasma experiments, planned on ITER in the near future. To carry out these studies, it is essential to develop novel diagnostic systems, such as fusion product measurement systems and high-resolution, high-reliability profile measurement of various plasma parameters. Scientific research on "Advanced Diagnostics for Burning Plasma Experiment" was assigned as a priority area by MEXT in 2004, and more than 20 studies are currently underway under this program. The feasibility of several new diagnostic concepts applicable to ITER is examined and diagnostic components for these systems are now under development.

Responses of two lines of feline T lymphocytes, FeT-J and FL-4, to ionizing radiation were examined in the present study. FL-4 cells, but not FeT-J, were persistently infected with feline immunodeficiency virus. Cells were irradiated with 
Co-
rays at 2 Gy/min. Surviving fractions were evaluated with clonogenic assay. Apoptosis was detected using TdT-mediated dUTP-biotin nick end labeling (TUNEL) method. Changes in nuclear morphology of viable cells were evaluated by double staining with Hoechst 33342 and ethidium bromide. Mean surviving fractions of FL-4 cells were slightly higher than FeT-J for each radiation dose given. However, dose required to reduce to 63 % of surviving fraction was 1.9 Gy in both cell lines. TUNEL assay, however, revealed the maximum frequency of apoptosis in FL-4 cells (
20 %) was lower than in FeT-J cells (
40 %). The time of frequency peak of TUNEL-positive cells in FL-4 was shorter than that of FeT-J. FL-4 cells reached peak level within 24 hours after irradiation, but FeT-J cells needed later than 48 hours after irradiation. Exposure of FL-4 cells to rays resulted in the giant- and the multi- nucleus formation. Nuclear swelling occurred to less extent in FeT-J than FL-4 cells. In conclusion, we found the difference in cellular responses to radiation in two lines of feline T lymphocytes. Modes of cell death of FL-4 cells were non-apoptotic and more research would discover new mechanism associated with apoptosis.
