Results suggested that Terminalia catappa leaves have no effect on cell viability of SCC-4 cells. The modified Boyden chamber assays revealed that a treatment of Terminalia catappa leaves significantly inhibited the cell motility/invasion capacities of SCC-4 cells.

在本实验中，利用 50%酒精萃取的榄仁树的叶之萃取物处理 SCC-4 细胞株，并利用 MTT assays 分析方法显示榄仁树的叶萃取物并不会影响 SCC-4 细胞的存活率，而当癌细胞转移时常常会伴随著细胞外基质的分解及细胞移动能力的改变，接著我们利用 modified Boyden chamber assay 发现榄仁树的叶萃取物具有抑制 SCC-4 细胞的移动与侵袭能力。

This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.
