Ornithine decarboxylase, a rate-determining enzyme of the polyamine biosynthetic pathway, is involved in the control of cell cycle, differentiation, cell growth and apoptosis. Previous studies described that protein kinase Cd regulates ODC activity. In this thesis, human leukemia cell line, HL60 cell, was used for the treatment with a specific PKCd inhibitor, rottlerin, to measure the effects on cell growth.

鸟胺酸去羧化（ornithine decarboxylase，ODC）为多胺酸起始与决定反应速率的酵素，对细胞周期、细胞生长、分化及细胞凋亡扮演一重要角色；在寻找肿瘤治疗及预防药物研究中，纯化植物天然物质是其中来源之一，研究者筛选药物时，测定对鸟胺酸去羧化活性是否具抑制效果是一个重要的试验。

而量子力学的计算结果显示出酵素催化反应里所产生的种种效应都对在三环马可尼可夫碳阳离子的去质子化步骤中立体化学特性有重大影响。

The structure and 5-HT immunoreactivity in the brain and suboesophageal ganglion of three beetle s, Ambrostoma quadriimpressum, Henosepilachna vigintioctomaculata and Oxycetonia jucunda, were first studied by means of colophony-paraffin embedding serial section technique and strepteavidin-peroxidase immunohistochemical method.

采用树脂石蜡组织包埋连续切片技术，结合免疫组化链霉菌抗生物素蛋白-过氧化物酶染色法，首次对三种甲虫(榆紫叶甲、小青花金龟、马铃薯瓢虫)的脑进行了详细观察研究，分析了三种甲虫脑组织结构特征，初步构建了三种甲虫脑内5-HT抗原系统免疫组化反应模式。

The structure and 5-HT immunoreactivity in the brain and suboesophageal ganglion of three beetles, Ambrostoma quadriimpressum, Henosepilachna vigintioctomaculata and Oxycetonia jucunda, were first studied by means of colophony-paraffin embedding serial section technique and strepteavidin-peroxidase immunohistochemical method. The results showed that the brains of these three taxonomically closely related beetles were remarkably different in composition and size.
