时差N小时 动物也会患关节炎?(上)（在线收听）

Did You Know That Moose Can Have Arthritis?

糜鹿也有关节炎？

It’s easy to tell, even at a glance, that people and moose are pretty different. Moose, at least males, have big, wing shaped antlers. People have no antlers. Moose are herbivores, eating only plants.

人们很容易就能看出，人与麋鹿有很大的不同，甚至一眼就能看出来。麋鹿，至少雄性糜鹿拥有庞大的，翅膀状的鹿角。而人没有鹿角。糜鹿是食草动物，只吃植物。

We eat mostly junk food. Despite their salad only diet, moose can weigh as much as 1400 pounds. Even the fattest humans top the scales at only around 1000 pounds. The list goes on.

我们却几乎一直吃垃圾食品。尽管只吃“色拉”，糜鹿的体重却高达1400磅。而人类最胖的也只有1000磅。二者的此类差异不胜枚举。

And yet, in some ways, people and moose are similar. For example, both suffer from arthritis.

但是在某些方面，人与糜鹿是相似的。例如，两者都饱受关节炎的困扰。

And that’s interesting because how and why moose develop arthritis may be able to tell us something about the pathology of the human variety.

这个问题很有趣，因为研究糜鹿患关节炎的过程和原因，可能有助于我们发现一些人类患关节炎的病理。

For example, researchers working in Michigan’s upper peninsula have been studying moose there for decades. And one thing they’ve found is while arthritis in moose is partly genetic, it’s also triggered by the environment.

例如，数十年来，位于密西根湖上游半岛的研究人员对糜鹿进行了研究。他们发现，糜鹿患关节炎在一定程度上是由基因引起的，同时也受到环境影响。
