We biopsied 1-2 single blastomere from 6-8 cell cleavage stage intracytoplasmic sperm injection embryo, and using nested PCR amplified the high frequently mutation region G380R of FGFR3 gene of the single blastomere. The products of PCR were digested by restriction enzyme Bfm Ⅰ, then the digested products were detected by 10% PAGE to see whether the embryo inherted the mutation of the patient and to screen out normal embryo transfer.

Among the various conductive fillers, carbon fibers have been proved to be a good candidate for EMI shielding. However, the electrical resistivity of a carbon fiber is much higher than the metal filler, so it must to use a greater number of carbon fibers in order to achieve the same shielding effect. In recent years, the Electroless plating is the new techniques of surface treatment of carbon fibers used to improve the electrical conductivity of carbon fiber. The copper-coated and nickel-coated carbon fibers have been proved to be a good candidate for EMI shielding.

导电高分子填充材料多使用碳纤维、碳黑及金属粉末，其中碳纤维具有高导电性、低密度及复合材料之补强特性，故本研究碳纤维作为填充材料，将碳纤维经过无电电镀处理，使其表面分别披覆金属镍及铜，增加碳纤维之导电度，混掺於聚丙烯高分子基材中，制成具有电磁波屏蔽功能之高分子复合材料，研究不同高分子成型方式与金属镀层对於碳纤维电学性质及复合材料电磁波屏蔽效益之影响。

The oligomeric states of PSⅡcomplex in soybean leaves treated with moderate light (700μmol〓) and strong light (2000μmol〓) were studied by nondenaturing PAGE and gel filtration chromatography. The following results were obtained. PSⅡ dimers resolved by nondenaturing PAGE accounted for about 75% of total PSⅡ complexes and there was no significant difference in the ratio of PSⅡ dimer to monomer between samples from moderate light-treated and fully dark-adapted leaves.
