Description

To evaluate the cytocidal effect of 125IUdR in human glioma cell line SHG44, 125IUdR were added to the RPMI1640 culturing medium. The amount of 125IUdR uptake by SHG44 cells was evaluated through measuring the radioactivity per cell; the killing effects of 125IUdR on SHG44 cells were estimated by colony forming method. The amounts of 125IUdR uptake by SHG44 were growing up as a function of 125IUdR dose in the medium (r = 0.9917). The surviving fraction was correlated with the concentration of 125IUdR (r = -0.9736). The LD50 of 125IUdR group was (8.7 +- 0.12) kBq/mL and the surviving fraction of 125IUdR group was significantly lower than that of Na125I group (P < 0.001). 125IUdR can be incorporated into the SHG44 cells, and the concentration of 125IUdR in SHG44 cells was influenced by 125IUdR dose in the medium. The inhibitive effects of 125IUdR on SHG44 cells were obviously
