apoptosis in human acute lymphoblastic leukemia cell line Molt-4 cell and macrophage cell line ANA-1 cell were induced by fission product 147 Pm. The cumulative absorption dose of 147 Pm in cultural cells through different periods were estimated. The morphological changes in Molt-4 and ANA-1 cells were observed by fluorescence microscopy and microautoradiographic tracing. Molt-4 and ANA-1 cells internally irradiated by 147 Pm were found
displayed a significant nuclear fragmentation and a marked pyknosis in immune cell’s nuclei
as will as DNA chain fragmentation and apoptotic bodies formation. The microautoradiographic study showed that 147 Pm could penetrate cell membrane and displayed membrane-seeking condensation in cells. At the same time
the membrane-bounded apoptotic bodies were observed. Experimental results in recent study provide evidence that Molt-4 and ANA-1 immune cells undergo apoptosis while internally irradiated with 147 Pm.
