DNAs were extracted from R. anatipestifer strain Jb 2 , Jb 3 , E. coli strain E 4 ( from duck ) and K 12 , and unidentified strain Tb 1 by phenol and chloroform extract method .

采用苯酚－氯仿混合法，提取了鸭疫里氏杆菌（Riemerelaanatipestifer）血清1型Jb2株、Jb3株、未定型菌Tb1株以及鸭大肠杆菌E4株和大肠杆菌K12株的基因组DNA。

Results The emulsifiers such as stearate , MAP , Brij 72 , Brij 721 were not suitable for preparation of salicylic acid ointment . K 12 and its mixture with Arlacel 165 can stabilize salicylic acid ointment .

结果硬脂酸盐、MAP、Brij72、Brij721等乳化剂不适合用于水杨酸软膏的制备，K12及其与Arlecal165的复配物作乳化剂则能制备稳定的水杨酸软膏。

In castrating female rats , the situation was different from that in male rats , the value of K 12 increased , K 21 reduced , K 02 increased , and SP 1 / 2 shortened in jejunum , implying that the ability of iodine absorption increased .

去势雌鼠空肠K12值升高，K21降低，K02值增加，SP1／2缩短，说明其吸收碘的能力增强。
