菌苗

Thus a strong resistible barrier was established in the animal.

表明弱毒苗和弱菌苗通过消化道粘膜免疫均可导致蛋鸡产生较多的SIgA阳性细胞，从而使消化道和呼吸道形成较强的免疫防御屏障。

We can only speculate on why later nominations highlighting the contributions of scientists such as Jonas Salk, Hilary Koprowski, and Albert Sabin in the development of poliovirus vaccines have not been recognized by a Nobel Prize.

我们只能推测为什么后来提名的科学家（如JonasSalk，HilaryKoprowski，AlbertSabin在发明脊髓灰质炎菌苗的过程中有辉煌的贡献）没有获得诺贝尔奖金。

Shortly thereafter, Dr. Albert Sabin, also an American physician and scientist, developed a live-virus vaccine against polio.

从那以后很快， Albert Sabin博士(也是美国的一位内科医生以及科学家)又改良成功了一种活性的口服菌苗。

As a result of such potential problems, the development of scrub typhus vaccines should be pursued.

传统的恙虫病疫苗研究主要是集中在灭活和减毒的菌苗，但一直未获满意结果。

This study played the basis for the research of StxB immunoprotection and the construction of Shigella dysenteriae type 1 candidate vaccine.

这为研究志贺氏毒素B亚单位的免疫保护作用和痢疾志贺氏Ⅰ型菌苗的研制打下了基础

The height of terminal buds, leave area and induction of adventitious roots of Ginkgo biloba were studied by adding of different concentration rare earth [La(NO3)3] in mediums of MS0 and 1/2 MS+0.5 mg/L IBA.

以银杏成熟胚诱导的无菌苗茎段为外植体，探討稀土[La(NO3)3]对其茎段顶芽高度、叶面积及芽苗不定根发生的影响。

Key words:Pueraria thomsonii Benth.; Test tube tuberous root; Induction technology

目的建立粉葛无菌苗培养及离体条件下诱导试管块根的体系。

The results were as follows:1 The optimum sampling period of Silvervein Creeper and Virginia Creeper is April and July, the germinating rate is high, and grows quickly

花叶爬山虎和五叶爬山虎最佳的采样时期都为4月和7月，萌芽率高，无菌苗生长快；

For the bud directly differentiation , the suitable culture medium was MS+BA 2mg/L +NAA 0.2mg/L or MS+TDZ0.01mg/L +NAA0.2 mg/L, of which the induction rate was 88% and 100% respectively. An efficient tissue culture system has been developed with the bud of mature seed of Aesculus hippocastanum L. as explants . Buds were induced from 2cm high young plantlet cultured on MS medium supplemented with 0.6 mg/L 6-BA plus 0.1mg/L or 0.4~0.6mg/L ZT plus 0.1 mg/L NAA for 15 d, and the induction rate was 100%, the mean No. of buds was 35.7; The combination of MS+0.2mg/L 6-BA +0.1mg/L NAA + 10mg/L AD was the suitable culture medium for elongation of the buds.

以欧洲七叶树成熟种子的胚芽进行离体培养和快速繁殖，结果表明：高约2cm的无菌苗在MS+0.6mg／L 6-BA+0.1 mg／L NAA或MS+0.4～0.6mg／L ZT+0.1 mg／L NAA培养基上培养15 d左右可诱导出不定芽，分化频率为100％，平均每株产芽35.7个；MS+0.2mg／L 6-BA+0.1mg／L NAA+10mg／L AD培养基有利于芽伸长；生根培养基为1／2MS+0.4 mg／L NAA+0.2mg／L IBA时，生根率可达75％。

Calluses were induced from hypocotyl segments of seedlings of Alhagi pseudalhagi on MS medium supplemented with 1. 5-2. 0mg/L 2, 4-D and 0.5-1. 0mg/L 6-BA.

骆驼刺种子无菌苗下胚轴切段在含1.5-2.0mg／L2，4-D和0.5-1.0mg/L6-BA的MS培养基中可100％诱导产生愈伤组织，并在相同培养基上进行继代培养。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
