查询词典 dose rate

In the chapter 4, the HPLC analyses of Uridine and Thymidine implanted by ions with high energy are done. The result shows that the dose effect curves of ions with high energy are almost the same to the dose effect curve of ions with low energy. At the beginning, the damage of implanted ions to the sample is large, with the dose increasing, the damage drops sharply.

Results:①The amount of human colon carcinoma cell line SW480 treated by quercetin decreased. The morphology of partial SW480 cells was shrunk volume, integrated cell membrane, condensed cytoplasm, pyknotic chromatin, nuclear fragmentation. Apoptotic Corpuscles were found by electron microscope.②MTT colorimetric assay showed quercetin inhibited the growth of human colon carcinoma cell line SW480 in a time- and dose-dependent manner when the concentration of quercetin was 30、60、90μmol/L.③Flow cytometry analysis showed the cell cycle of SW480 cell was restricted in G1/S. G0/G1 phase rate increased and S phase rate decreased with increasing concentration of quercetin and time lasting.④ Zymogram analysis assay showed the secretion of matrix metalloproteinases in human colon carcinoma cell line SW480 treated by quercetin decreased.
