Results Chromosomal changes were detected in 4 cases by high-resolution G-banding: one case with t(4;6)(q23-24;p21), one case with longer p arm of chromosome 21 (21p+), and two cases with pericentric inversion of chromosome 9 inv(9 which was confirmed by C-banding.

There are two parts in this thesis. Part I focuses on the transient effect in InGaP/GaAs hetero-junction bipolar transistors. Part II focuses on the P memory effect and buffer-layer-quality determination using C-V measurement in AlGaAs/GaAs pseudomorphic high-electron-mobility transistors. The characterization of hydrogen passivation for InGaP HBTs grown on semi-insulating GaAs substrates is studied. The transient effect caused by hydrogen passivation results the current gain ?

本论文分两部分，第一部份讨论在磷化铟镓的异质接面双载子电晶体中，由於氢的包覆效应产生的特性之研究，由於氢在此种元件中所造成的载子包覆现象是引起电流增益增加的暂态现象的主要原因，本论文提出一个计算氢包覆比例的模型，并与SIMS量测的结果相比对，经过几次热回火处理，此种暂态效应可以被消除。

Flow cytometry was used to quantitively investigate apoptosis of HT29 cells and regulating expression of tumorrelated gene expressing protein.

结果 浓度≥100U／ml的IFN-γ能抑制HT29细胞增殖，作用呈时间依赖性，在24、48、72h抑制率分别为13％、32％、44％；流式细胞仪检测表明IFN-γ可诱导细胞凋亡，降低癌基因蛋白c-myc、bcl-2表达而促进bax表达（P〈0.01）。

Second, residues in the reactive site of the inhibitor were replaced by the consensus substrate recognition sequence of furin, namely, Arg at P_1, Lys at P_2, Arg at P_4 and Arg at P_6. In addition, the P_7 residue Asp was substituted with Ala to avoid possible electrostatic interference with furin inhibition. Finally, the extra N and C terminal residues beyond the doubly conjugated disulfide loops were further truncated. However, all resultant synthetic peptides were found to be temporary inhibitors of furin and kexin during a prolonged incubation, with the scissile peptide bond between P1 and P'1 cleaved to different extents by the enzymes.

高活性、低分子量的furin酶抑制剂有可能发展成为新型的抗细菌内毒素和抗病毒感染的药物，我们以绿豆胰蛋白酶抑制剂Lys片段长链22肽为模板，设计了一系列能抑制furin和kexin活性的突变体，采用如下三种方法逐步优化：一、去除Lys片段长链三对二硫键中的一对，用Ser替换Cys，减少可能存在的二硫键错误配对；二、抑制剂的活性中心根据furin底物的专一性逐步改变，即P1、P2、P4和P6位分别变为Arg、Lys、Arg和Arg，同时为了避免P7 Asp和P6 Arg之间可能存在的相互作用，将P7位Asp替换为Ala；三、将两对二硫键形成的双环的外面5个氨基酸残基去除。
