One double-blind trial found that co-administration of 100 mg of Asian ginseng extract with a flu vaccine led to a lower frequency of colds and flu compared to people who just received the flu vaccine alone.

7一个双盲试验发现导致感冒和流感较低频率流感疫苗亚洲100毫克人参提取物联合政府的人相比，谁刚刚收到的流感疫苗单。7

The inhibiting influenza A virus effect of catechu extract was observed by means of chick-embryo culture , and the inhibitory activity of catechu extract on influenza A virus in vitro was observed by the hemagglutination inhibition test.

用狗肾传代MDCK细胞培养法观察儿茶提取物抑制甲型流感病毒的致细胞病变作用；用鸡胚培养法观察儿茶提取物抑制甲型流感病毒增生的作用；用红细胞凝集试验观察儿茶提取物体外直接抑制甲型流感病毒的作用。

Some key techniques related to the close and continuous process were investigated by the application of H9N2 avian influenza virus with Vero cells, such as the susceptibility of cell to influenza virus, virus production with cell microcarrier culture method, cell bead-to-bead transfer, virus production through bead-to-bead transfer, cell culture and virus production with serum free medium, metabolism analysis, and repetitiously intermittent bead-to-bead transfer of cell for virus production to simulate the close and continuous process.

通过使用Vero细胞增殖禽流感病毒H9N2，本文针对封闭连续工艺过程的一些关键技术开展研究，包括细胞对流感病毒敏感性分析、细胞微载体培养生产病毒工艺、细胞珠到珠转移、转移后细胞对病毒增殖敏感性验证、细胞无血清培养生产流感病毒、代谢分析、可模拟连续操作的多次间歇式珠到珠转移培养细胞生产流感病毒等方面。

Pigs can be infected by avian influenza and human influenza viruses as well as swine influenza viruses. When influenza viruses from different species infect pigs, the viruses can reassort i.e.

禽流感，人流感以及猪流感病毒都会对猪造成感染；当不同种来源的流感病毒同时感染时，病毒之间就会重新&洗牌&，从而产生一种新的&禽人猪&混合病毒。

Pigs can be infected by avian influenza and human influenza viruses as well as swine influenza viruses. When influenza viruses from different species infect pigs, the viruses can reassort (i.e. swap genes) andnew viruses that are a mix of swine, human and/or avian influenza viruses can emerge.

Many swine influenza viruses are a result of reassortment and their genes are composed of human and avian and/or swine virus genes.

许多新的猪流感病毒是猪流感病毒基因和人、鸟流感病毒基因杂交后重排产生的。

Flu viruses mutate constantly, which is why the flu vaccine is changed every year, and they can swap DNA in a process called reassortment.

流感病毒一直在变异，同时流感疫苗也每年在变。不同流感病毒的DNA能在重配的过程中交换。

No, canine influenza was diagnosed initially in 2004. Until this year, outbreaks seemed to be contained to greyhound racetracks and seemed to affect only racing dogs.

狗流感和之前影响马的流感病毒有相关性，从某种程度上可以说，这种病毒是马流感病毒变异之后，形成了从马到狗之间传播的能力。

I urge any American living outside the country to get an early start checking his/her registration and receiving an absentee ballot, because it can take a while.

我奉劝身在国外的所有美国人早点着手核对登记表，并接收缺席选举人票，因为这得花点时间。

He is too young to join the army.

他太年轻了，还不能参军。
