The apoptosis in human bone tumor cells induced by internal irradiation with 153Sm was studied. The morphological changes in bone tumor cells were observed by electronic and fluorescent microscopy, as well as DNA agarose gel eletrophoresis. DNA chain fragmentation, microautoradiographic tracing and the inhibition rate of prolif- eration in bone tumor cells exposed to 153Sm with different duration time were examined. It was demonstrated that the bone tumor cells exposed to 153Sm displayed nuclear fragmentation, pyknosis, margination of condensed chroma- tin, and formation of membrane bounded apoptotic bodies, whereas the percentage of DNA chain fragmentation of bone tumor cells increases in direct proportion to the duration of irradiation with153 Sm, as well as DNA ladder for- mation in apoptotic cells. Also a marked inhibition effect of proliferation in bone tumor cells after exposure with 153Sm was observed.

The resistivity-gradient-driven turbulence is investigated in the presence of both poloidal and parallel/toroidal *** saturation,the poloidal flow shear reduces fluctuations at the edge of plasmas,the parallel flow and its shear both reduce fluctuations in the core of *** indicates that the mechanism for a high confinement regime(H mode)may be the turbulence suppression due to the poloidal flow shear at the edge of plasmas,and the mechanism for a very high confinement(VH mode)may be the turbulence suppression due to the toroidal flow and its shear in the core of plasmas.
