Dynamic renal imaging studies were performed in 132 patients using 99m Tc DTPA and 131 I OIH. Effective renal plasma flow(ERPF) and glomerular filtration rate(GFR) was obtained. GFRs were calculated with 2 background regions of interest(ROI),conventional subrenal areas(SB) and suprarenal areas(SP). The relative renal functions(RR) obtained by GFRs determination was significantly higer compared with that by ERPF. These results suggested that the RR of impaired kidney determined by GFR(SB) was obviously higher than that assessed by ERPF. Higher coefficient( r value) was gotten with GFR(SP) than with GFR(SB).Results suggested that the GFR obtained with conventional subrenal background ROI might overestimate individual renal function of the poorly functional kidney and the GFR estimated by suprarenal background ROI might be more accurate.

Microtubule is one of the key components of the cytoskeleton and plays an important role in the maintenance of cell shape and the process of signal transduction and mitosis. Due to the extreme importance of microtubule in the process of mitosis, tubulin becomes one of the most important targets for development of new anticancer drugs and tubulin inhibitors are used for the treatment of cancer nowadays. These inhibitors have antitumor activity by inhibiting or promoting the assembly of tubulin to microtubules and interfering the process of cell mitosis. This review summarized the research progress of the tubulin inhibitors, especially the introduction of the tubulin inhibitors of pharmacological activities and the progress of clinical research. Also, the development trend of these inhibitors is discussed.
