For type I diabetes, insulin is the only treatment option.

对于1型糖尿病，使用胰岛素是唯一的治疗方法。

People with type I diabetes don't make enough insulin, and use exogenous insulin meaning an injection or infusion of insulin.

I型糖尿病患者不能合成足量胰岛素，而使用外源性胰岛素，即注射胰岛素。

But in type I diabetes, the immune system destroys the islets.

但在 I 型糖尿病中，免疫系统会破坏胰岛。

The researchers were hoping to transplant new islets into rats with type I diabetes to get them to start producing insulin again.

研究人员希望将新的胰岛移植到患有 I 型糖尿病的大鼠体内，让它们重新开始产生胰岛素。

That was a big deal on its own, but originally, the researchers also wanted to try transplanting clusters of the pancreas cells, called islets, into rats to suppress type I diabetes.

这本身就是一件大事， 但最初，研究人员还想尝试将胰腺细胞簇（称为胰岛）移植到大鼠体内以抑制 I 型糖尿病。

They took islets from the mouse pancreases grown in the chimeras and transplanted them into mice with type I diabetes, so the mice started producing insulin again and the disease was suppressed.

他们从嵌合体中生长的小鼠胰腺中取出胰岛，并将其移植到患有 I 型糖尿病的小鼠体内，因此小鼠再次开始产生胰岛素，疾病得到抑制。

People with type I diabetes don't make enough insulin, so when they eat a meal—especially a meal with a lot of potassium— that potassium sits in the blood instead of being taken into cells, and this causes hyperkalemia.

一型糖尿病患者胰岛素分泌不足，所以当他们用餐后，尤其是餐内含钾较多时，钾会聚集在血中而不是被运输进细胞，这就造成了高钾血症。
