Comparison of the Efficacy of Bismuth-based Triple Therapy and Antioxidant Therapy in Treating Ferrets Infected with Helicobacter Mustelae

抗菌三联与抗氧化疗法在幽门螺杆菌感染动物中的比较

Its average length is 20 in. (51 cm), including the 5-in. (13-cm)tail, and it weighs about 2 lbs (1 kg). It was originally domesticated for hunting mice, rats, and rabbits; today ferrets are commonly kept as pets.

普通雪貂的体形亦较艾鼬为小，身长平均51公分，包括13公分的尾长，体重约1公斤。原本饲养雪貂来抓老鼠，现在则是拿来当宠物。

||1: Dr Raichlen hypothesised that endocannabinoid-driven exercise highs would be found in those mammals that gain an evolutionary benefit from being fast on their feet: antelopes, horses and wolves, for example. ||2: However, he also thought that they would not be present in those which are known for being quick and agile, but not for running, like ferrets . ||3: To test these ideas, he and a team of colleagues devised an experiment that monitored the endocannabinoid levels of different species after they had been walking or running on a treadmill.

||1:Raichlen先提出了一个假设：像羚羊，马和狼这样一些因拥有"飞毛腿"而在进化过程中受益的哺乳动物中也存在着"锻炼产生的兴奋"现象。||2:而那些以灵动著称，却非凭奔跑文明的动物，如雪貂，则不会出现此现象。||3:为了检验这些猜想，Raichlen和由其同事所组成的团队设计了一个实验——对在跑步机上行走，奔跑过后的动物体内的endocannabinoids水平进行监控。

||1: The experimental animals in question were ten people, eight dogs and eight ferrets . ||2: Dr Raichlen had them run or walk on the treadmill for 30 minutes. ||3: Since running and walking speeds differ from species to species, the speed at which the treadmill moved was varied so that it raised the heart rates of the different participants to the same level. ||4: Running speeds were thus set at 2.5 metres a second for people, 1.83 for dogs and 0.84 for ferrets . Walking speeds were set at 1.25 metres a second for people and 1.1 for dogs. ||5: The ferrets proved too easily distracted to walk consistently on the treadmills and were thus left to sit quietly in their cages for this part of the study. ||6: Each participating animal ran for one session and walked for one other, and did so on separate days, to avoid exhaustion. ||7: Before and after each session, blood was drawn from each and the endocannabinoid levels in it were measured.

||1:被考虑用来进行实验的动物有以下三种：十个人，八条狗和八只雪貂。||2:Raichlen博士先让他们在跑步机上行走或奔跑30分钟。||3:由于不同的动物速度不一，所以跑步机的传送带速度设置是以使不同动物的心率达到同一水平为依据。||4:这样设置的结果便为：奔跑速度为人类2.5米/秒，狗1.83米/秒，雪貂0.84米/秒；行走速度为人类1.25米/秒，狗1.1米/秒。||5:雪貂由于太易分心，没办法让它持续在跑步机上行走，所以在进行该部分实验时它们被留在了笼中静静地坐着。||6:每只动物会跑一段走一段，为了避免动物们出现筋疲力尽的情况，实验是分成几天进行的。||7:在实验前和试验后，动物们都会被抽血以检验其中的endocannabinoid水平。

||1:Dr Raichlen argues that it makes sense for ferrets not to have systems that reward cardiovascular activity, since such exercise consumes a lot of energy, may cause injury, and is not crucial to the stealthy hunting technique of sneaking down burrows and killing rabbits in their sleep.||2:What is not clear is whether the endocannabinoid reward is an ancient mechanism that has been lost on branches of the mammalian tree that do not need it, or is something that evolves quickly in species which become active.Given that humanity’s arboreal simian ancestors would presumably have had little need to run, it is probably the latter.||3:But to be sure Dr Raichlen will need to put animals far less co-operative than ferrets on the treadmill.

||1:看来雪貂体内并不存在对心血管活动进行阳性强化刺激的系统，Raichlen博士认为这对雪貂的发展同样是有意义的，要知道太剧烈的运动会消耗掉过多的能量， 甚至引发受伤，且这并非是雪貂捕猎技术中的关键——它们一般只需偷偷溜进兔子窝并在兔子们熟睡时将其杀死即可。||2:仍有待考证的是，究竟这种endocannabinoid刺激机制是从远古时代起即为哺乳类动物所拥有（但在一些不需此机制的哺乳类分支中渐渐退化），还是从某些活跃的个别物种中进化出来的？鉴于人类的祖先—类人猿是树栖动物，据推测它们很少有奔跑的需要，因此正确结论很可能是后者。||3:但若要确认此假设，Raichlen博士需将更多如雪貂般不太合作的动物哄上跑步机。

||1: The researchers report in the Journal of Experimental Biology that, after 30 minutes of walking (or sitting in a cage), participants’ endocannabinoid levels did not rise. ||2: After running, however, the average human’s endocannabinoid levels rose from 2.4 picomoles per millilitre (pmol/ml) to 6.1. ||3: Dogs showed a similar trend, with levels rising from 2.4 pmol/ml to 8.0. ||4: Ferrets were different. Although they did show an increase, from 3.0 to 3.9 pmol/ml, this was not a statistically significant rise. ||5: These findings suggest that dogs experience a "runner’s high" but ferrets do not.

||1:研究人员在《生物学实验》杂志中提到，在经过30分钟的行走（雪貂是呆在笼中）之后，参加实验的动物的endocannabinoid水平并没上升。||2: 然而在奔跑过后情况则有所不同：那10个人的平均endocannabinoid水平从2.4 pmol/ml上升到了6.1 pmol/ml。 ||3: 狗的变化趋势与人类似——由2.4 pmol/ml升至8.0 pmol/ml。 ||4: 唯独雪貂例外。他们的endocannabinoid水平虽亦有所上升——3.0 至 3.9 pmol/ml，但仍处于统计学上可不被纳入考虑的范围内。 ||5:这些发现表明狗中同样存在着"赛跑者的亢奋"现象，而雪貂则没有。

And so it proved. When they tested it on ferrets (often used as proxies for people in these sorts of studies), it passed through the air from one animal to another. Moreover, closer inspection showed that two other mutations, N158D and T318I, had spontaneously got tangled up in the mix.

而他们确实也做到了。通过在雪貂（在此类实验中通常用来代替人类）身上的实验证明，此病毒能通过空气在动物之间传播。此外，进一步观察表明，两种其他的变异基因—N158D和T318I也自发地产生并整合入已变异的病毒基因中。

Food habits of Siberian ferrets (Mustela eversmanni) were analysed with 133 piles of feces collected in Badaerhu Farm and its surroundings.

All Ferrets are born deaf. They will begin to hear around 34 days.

所有雪貂生下来是听不见的。他们的听觉大约在出生34天后出现。

Ferrets are born with their eyes shut. They will begin to open around 34 days. (Day 34 is going to be a good one)

所有雪貂生下来眼睛都是闭着的。大约在出生34天后他们才开始睁开眼睛。（34天真是个好数字啊，哈哈）

It was set in 1981 by Reg Mellor, whose trick was to make sure the ferrets were well-fed before putting them in his pants.

他的秘诀在于要确保雪貂放进裤子之前已经被喂饱了。

The study also included experiments in a veritable menagerie of animals, including mice, miniature pigs, ferrets and macaques.

这项研究也使用了尽可能多样的实验动物，包括小鼠，小猪，果子狸和恒河猴。
