菌苗

The establishment of germfree plantlet: Used 1/2MS + agar + sucrose, the burgeoning rate was high and plant was strong.

结果表明：(1)无菌苗的建立：用1/2MS+琼脂＋蔗糖，出苗率高（90%上）、苗壮。

The cotyledon explants excised from 5-day-old germfree seedlings were cultured on the MS medium containing 1.0 mg/L 6-BA in darkness for 3 days, and then further cultured under light condition for induction of adventitious buds.

结果显示：将从5 d龄甜瓜无菌苗上切取的子叶外植体接种在MS+6-BA1 mg/L的不定芽诱导培养基上，黑暗条件培养3 d，再转至光下继续培养，诱导出高效不定芽丛。

Formalin and phenol and heat killed cells of Vibrio harveyi were prepared to show immunogenicity to Caressius auratus gibel by examination of agglutinating antibody litres of serum as well as phagocytic activity of blood leucocytes.

结果表明，3种方法制备的V.harveyi菌苗注射接种异育银鲫后第29d，受免异育银鲫血清中凝集抗体效价均不同程度地上升，其中以F一VH免疫组最高，P一VH免疫组其次，再次为H一VH免疫组。

Gibel carp were inoculated with formalin killed Aeromonas hydrophilaand fed with diets supplemented with appropriate amount of yeast β-glucan. 28 days after the inoculation, the infulence of dietary yeast β-glucan on the resistance of gibel carp against Aeromonas hydrophila were determined by examing their gained weight, agglutinating antibody titer, lysozyme activity, phagocytic activity and relative percent survival by challenging with live A.

在饲料中添加定量的酵母β-葡聚糖，投喂经注射接种福尔马林灭活的嗜水气单胞菌(Aeromonas hy-drophila)菌苗的异育银鲫28 d后，通过测定供试鱼的增重量、血清中凝集抗体效价、溶菌酶活性、谷丙转氨酶活性、血清总蛋白含量、白细胞吞噬活性以及活菌攻毒后的免疫保护率，探讨了酵母β-葡聚糖对受免异育银鲫免疫应答的增强作用。

Different plant hormones and their different concentration ratios have different effects on the callus of Halenia elliptica D.

结论不同培养条件对椭圆叶花锚愈伤组织的诱导有不同的影响，其中以无菌苗的茎段为外殖体易形成愈伤组织。

Don.methodswith the stem of sterile seedling and fresh plants as exophyte, ms as a basic medium, 6-ba and naa hormone were adopted as the experimental variables.resultsms +1.0 mg / l 6-ba +1.0 mg / l naa induced the best effect of callus; higher concentrations of 6-ba with high concentrations of naa made callus densification and higher rate.conclusion different plant hormones and their different concentration ratios have different effects on the callus of halenia elliptica d.

方法以椭圆叶花锚种子培养的无菌苗的茎和新鲜植株的茎段为外殖体，ms为基本培养基，分别以6-ba和naa两种植物激素为变量进行实验研究。结果ms培养基+1.0 mg/l 6-ba+1.0 mg/l naa对诱导椭圆叶花锚愈伤组织的形成效果最佳；高浓度的6-ba配合较高浓度的naa诱导的愈伤组织致密，出愈率高。

It has been found recently that the toxin gene ctxAB is carried by the lysogenic bacteriophage CTXΦ. The possibility in theory exists that the vaccine strain could reacquire ctxAB from a wild-type strain in the intestine or in the environment by horizontal transfer of CTXΦ.

但是，毒素基因ctxAB由溶原性噬菌体CTXΦ携带，可能在偶尔的情况下水平转移给减毒活菌苗，给其在现场应用的安全性带来了重大隐患。

Antipyretic, analgesic and anti-inflammatory effects of Malvastrum coromandelianumGarcke were tested by fever caused by typhoid-paratyphoid vaccine in rabbits; hot-plate, writhing, ear edema, and abdominal capillary permeability of mice.

摘 要 采用伤寒-副伤寒菌苗致热家兔法研究赛葵的解热作用，热板法和扭体法研究赛葵的镇痛作用，二甲苯致炎鼠耳肿胀法和腹腔毛细血管通透性法研究赛葵的抗炎作用。

Can animal models predict protection provided by meningococcal vaccines?

动物模型能够预测流脑菌苗的保护作用？

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。
