These two traditional Chinese medicine has a strong antibacterial activity and, more importantly, they have an advantage that lower toxicity than traditional disinfectant drug - Formocresol, CP. In order to help in the developmentof new strategies to prevent or eliminate the infection byE. faecalis, thereby improving treatment results in endodontics and give a reference to clinical application, In this research , using traditional Drug formocresol and the current most respected calcium hydroxide ( calcium hydroxide mixed with propylene glycol ) as the conventional control, we investigated the antimicrobial activity of Chinese herbs cinnamic aldehgd and Chinese gallnut against E. faecalis in root canals in vitro.

上述两种中药都具有很强的抗菌作用，更重要的是它们作为中药具有较传统消毒药物—甲醛甲酚、樟脑酚毒副作用小的优点，本研究通过离体牙根管消毒实验，并用传统消毒药物甲醛甲酚及当前最受推崇的氢氧化钙制剂做为常规对照，对两种中药的抗粪肠球菌性能进行评价，以期探讨更有效且安全的抑制或杀灭粪肠球菌的方法，提高根管治疗的成功率，为临床应用提供一定参考。

Under light microscope, the egg is an oblated and agglutinated demersal with a narrow perivitelline space; eggs ranged in diameter from 1.95 to 2.38 mm with a mean of 2.18 ± 0.03 mm; their membrane are smooth and they have 5 to 7 cannular keratose egg-filaments; the oil globules are multiple, ranged in diameter from 0.05 to 0.50 mm and in number from 7 to 145 with a mean of 28±2, the position of them migrate during embryonic development; the yolks are ivory-white with no segments, ranged in diameter from 1.00 to 2.30 mm with a mean of 1.90 ± 0.03 mm; the development phases of the embryo are variable. So they were identified as the eggs of one Beloniformes.

在光学显微镜下：卵呈微扁圆形，卵径1.95~2.38mm，粘着沉性；卵黄间隙较窄，卵黄囊呈乳白色，无龟裂；卵膜平滑，在其表面有5~7根细长角质管状卵膜丝；多油球数不定（4~145），油球径0.05~0.50mm，油球在卵黄囊中的位置随不同的发育时期而不断发生变化；胚体处在不同的发育阶段，其特征符合颌针鱼目鱼卵的特征。

The CDA gene shares high sequence similarity with that of fungi including Rhizopus oryzae (75%), CDA1(58%) and CDA2(56%) of Rhizopus circinans, Mucor rouxii(56%), Gongreonella bulteri(48%), Rhizopus stolonifer(39%), Phycomyces blakesleeanus(39%), CDA1(17%) and CDA2(16%) of Saccharomyces cerevisiae.

总状毛霉CDA基因与其它相近种米根霉、卷柄根霉的CDA1和CDA2、鲁氏毛霉、卵形孢球托霉、匍枝根霉、布拉克须霉、酿酒酵母的CDA1和CDA2的基因序列同源性分别为：75%、58%、56%、56%、48%、39%、39%、17%和16%；相应的氨基酸序列的同源性分别为：69.0%、57%、59%、55%、47%、30%、32%、18%、21%。

Methods: 60 freshly extracted , single-rooted premolars were randomly divided into two experimental groups (cinnamic aldehyde, gallnut decoction) and four control group (FC group, calcium hydroxide mixed with propylene glycol group, negative the control group and positive control group),.

标本牙去除牙冠部及根尖部，留取6mm长牙根，50颗牙建立粪肠球菌根管感染模型后，20颗牙根管内分别放置桂皮醛、五倍子水煎剂，另30颗感染根管放置FC、氢氧化钙丙二醇糊剂和生理盐水。

N algorithm for close approach determination was developed by Alfano and Negron （1993） based on polynomial splining techniques.

lfano—Negron（1993）提出的空间目标接近分析算法将最小相对距离及其对应时刻和进出误差椭球时刻的求解问题均转化为插值多项式求根问题。A—N算法在判断三次多项式根的存在性、筛选合理实根时存在缺陷，可能导致多余计算。

Water the plants and the soil they are to be planted in well. Then, dig a hole a little bigger than the root ball. Remove the plant from the pot and loosen the roots if needed. Place the plant in the hole and gently pack the soil around the plant to ensure good contact with the roots.

首先将要移出的花和土壤浇湿，然后在挖个比要移出的根球大的坑，接着把花从盆里移出来，有必要的话抖抖它的根，再栽到挖好的坑里，然后轻轻的拍拍它周围的土，让根和土壤得到很好的接触。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.
