After prolonged exposure to ANE, the accumulation of hyperploid cells, micronucleated or multinucleated cells were noted concomitantly with centrosome amplification.

另外，长时间的作用下多倍体，多核或微核细胞之有明显的增多，同时也发现常之中心体。

In summary, our results suggest that ANE increases micronuclei frequency, induces cell cycle arrest at G2/M phase, causes cytokinesis failure and accumulates hyperploid cells. The events are possibly associated with ROS production, actin filament disorganization and centrosome aberration.

故从本实验的结果，我们认为槟榔子萃取物会增加微核频，诱导细胞周期停滞於G2/M phase，造成细胞质分缺损与多倍体细胞的增多；而这些现象可能与活性氧的生成，actin filament 的常与中心体的变有关。

The effect of misch metal and yttrium on the ageing behavior of AZ91 magnesium alloy was investigated.Aluminum compounds of rare earth and yttrium with high melting point were crystallized fiirstly from the melt alloy during the solidifying process and pushed to the crystalllizing face of α phase to inhibit its growing,or became the nucleation of the matrix.
