In addition, serum amylase, lipase and bilirubin might sometimes be elevated.

此外，血清淀粉酶、脂肪酶和胆红素有时可能升高。

Alright, so the other type is bilirubin or pigmented gallstones.

胆红素结石，或称胆色素结石。

Well, actually pigmented gallstones are made of unconjugated bilirubin.

然而，事实上胆红素结石是由非结合胆红素构成的。

The brownness is due to this mix of unconjugated or hydrolyzed bilirubin and phospholipids.

结石的褐色源自未结合胆红素，或水解的胆红素，和磷脂的混合物。

These ones, again, are pretty self-explanatory and are made mostly of bilirubin and therefore are pigmented.

这类结石，顾名思义，主要由胆红素构成，因此含有色素。

Usually though, bile salts bind up the calcium ions and keep them from binding with and precipitating unconjugated bilirubin.

通常情况下，胆盐会结合钙离子，以此阻止钙离子与非结合胆红素结合并沉淀。

I thought there was only conjugated bilirubin in bile?

这是怎么回事？难道胆汁里不是只有结合胆红素？

Since it's the bilirubin in bile, we'd maybe assume that they're made of conjugated bilirubin, right?

由于是胆汁中的胆红素，我们大概会认为它们是由结合胆红素构成的，对吧？

Jaundice actually occurs when your blood contains an excess of the molecule bilirubin.

当您的血液中含有过量的胆红素分子时， 就会出现黄疸。

Recycling of that heme group yields unconjugated bilirubin, which at high concentration can cause scleral icterus, jaundice, and bilirubin gall stones.

亚铁血红素的循环利用会产生非结合胆红素，其浓度过高会导致巩膜黄染、黄疸与胆红素胆结石。
