The prediction of secondary structure showed that Family chensirin-2 and dybowsin-2 are extended coils, and the rest families have one or two a-helix where polar amino acids are located on one side of the helix wheel and apolar amino acids on the other side, attaching an amphiphilic property to the whole helix.

除dybowsin-2和chensirin-2家族为自由卷曲抗菌肽外，其余各类抗菌肽均能形成一段至两段a-螺旋结构，极性氨基酸和非极性氨基酸分别位于螺旋轮的两侧，使蝶旋呈两亲性。

MICs of the combination of cefoperazone or ceftazidime and levofloxacin were determined by the microdilution chequer board technique,interpretation of the results was made by calculation of FIC.

结果：头孢哌酮、头孢他啶和左氧氟沙星联合用药对铜绿假单胞菌的体外抗菌协同作用为35 5%～38 7％，相加作用为41 9%～45 2％，无关作用为16 1%～22 6％，无拮抗效应。

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。

This dissertation aims at finding anticancer and antibacterial polynuclear complexes targeting DNA with high activity and low toxicity. Sixteen compounds were synthesized, and characterized by means of X-ray single crystal diffraction, elemental analysis, molar conductivity and IR, and the influencing factors on structures of the compounds have been investigated. The actions of these compounds to DNA were also investigated by spectral, electrochemical and hydromechanical methods.
