As an alternative, Sterling and his colleagues combined isoniazid with another drug, rifapentine.

于是蒂莫西及其同事将另一种药利福喷汀与异烟混合在一起来代替传统的用药方法。

The most common approach is isoniazid for nine months.

最常见的用药方法就是异烟用9个。

Jacobs was studying whether the TB drug isoniazid was being inactivated by the presence of a particular amino acid, cysteine, which in chemical terms acts as a reducing agent, by donating electrons.

Jacobs 之前一直研究为何肺结核药物异烟会被氨基酸和半胱氨酸灭活，而异烟在应中通过失电子，起到还原剂的作用。

Vitamin B6 deficiencies can also commonly happen as a result of isoniazid treatment for tuberculosis, as isoniazid attaches and inactivates vitamin B6.

在使用异烟治疗结核病时，由于异烟会附着并灭活维生素B6，因而维生素B6缺乏症会较为常见。

Those at highest risk can take medicine, but Vanderbilt University researcher Timothy Stirling says not everyone follows through with the treatment, which is a daily dose of isoniazid for nine months.

然而，据范德堡大的研究者蒂莫西称，这些高危群可通过吃药来避免风险，但是有些不愿意在连续9个的时间里每天服用异烟（抗结核药）。

We saw that just like the other reducing agent, it in combination with isoniazid sterilized the culture.

我们看到它跟另一种还原剂相同，跟异烟一道将这些细胞灭活。

And the results of this study showed that the new regimen - the three months of isoniazid and rifapentine - was as effective as the nine-month isoniazid regimen.

该研究的结果表明，混搭后的药效与长达9个的传统用药药效一样好。

Tuberculosis treatments have been compromised because the Mycobacterium tuberculosis bacterium responsible has evolved resistance to both isoniazid and rifampin, previously the two most powerful antibiotics used against it.

结核病治疗已受影响， 因为导致该病的结核分枝杆菌已对异烟和利福平产生抗药性，而这两种药物曾是治疗该病最有效的抗生素。
