目的 旨在建立豚鼠单侧三个半规管阻塞的动物模型。

The principal purpose of this study is to set up the isolation methods for diphtheria toxin expressed by genes, to purify the toxin with complete biological activities, and to make researches on its toxicities. In the experiments, the target gene was inserted into the cloning vectors--pET22b, then the vectors were introduced into host cells -BL21(DE3). The expression of the toxin was induced by addition of IPTG. The expression products were purified by His-6 label affinity chromatography. Then the diphtheria toxin expressed was transferred to PVC membrane using semidry blotter to determine the amino acid sequence of N-terminal. The "nicked" diphtheria toxin linked by disulfide bond was gained by protease hydrolysis.

为建立重组基因表达白喉毒素的分离纯化方法，制备出具有生物活性的蛋白质毒素，构建了白喉毒素表达载体pET22b-DT，并转入大肠杆菌BL21(DE3)中诱导表达，以融合表达的His-6作为标签通过亲和层析纯化；表达毒素经蛋白酶酶切后，形成了以二硫键连接的与天然结构相同的带"缺口"的白喉毒素，并测定白喉毒素对豚鼠的急性毒性和细胞毒性。

Yang Xue Zhi Yang capsule has better effect on stopping itch,tonic therapy,raising the level of sex hormon and stimulating sebaceous gland secretion.

养血止痒胶囊对外源性组胺所致的豚鼠瘙痒模型有较好的止痒作用，对衰老血虚证大鼠模型有较好的养血作用，可提高其性激素水平，增加皮脂腺数目，改善皮脂腺分泌。

This rumbling is also made by guinea pigs when they hear sounds that they do not like (such as your upstairs neighbors banging on the floor, or a sharp snare drum on the radio), or when they want to warn others when something "isn't quite right".

当豚鼠听到它们不喜欢的声音时也会发出的这种隆隆声，（如您楼上的邻居家撞击地板的声音，或尖锐电台、音响的声音），或者当他们想提醒别人某事"完全不对"时。

AIM: To study the effects of sodium salicylate on the expressions of NGB mRNA and protein of spiral ganglion in guinnea pig.

目的： 观察水杨酸钠对豚鼠螺旋神经节NGB mRNA和蛋白表达的影响。

Domestic guinea pigs usually are kept in plastic cages with softwood chip bedding.

国内豚鼠通常存放在塑胶鸡笼与针叶树芯片寝具。

实验研究采用膜片钳技术，观察青蒿常山对豚鼠单个心室肌细胞钙和钾离子通道的影响。

In the experimental research, adopting the patch clamp techniques, study the effect of southernwood and Dichroa febrifuga on calcium and potassium ion channel in isolated myocytes of guinea pig.

实验研究采用膜片钳技术，观察青蒿常山对豚鼠单个心室肌细胞钙和钾离子通道的影响。

US troops were, according to this book and a lot of veterans groups, and at least one clinical study , used as guinea pigs to test this oil, which was not authorized for use on humans because of identified dangers and side-effects: There is compelling evidence that squalene causes crippling permanent autoimmune diseases.

根据这本书和许多退伍军人组织的叙述，至少有一个临床研究表明，美军就像豚鼠一样被用来测试这种石油。

Guinea pigs also squeal when they feel that they are in danger, which acts as a warning to others in the herd.

豚鼠觉得自己有危险的时候也会尖叫，这是警告群里的其他猪猪有危险的行为。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
