These stones, also like uric acid stones, are red-brown in color and radiolucent under an X-ray.

What that stuff is is uric acid.

AVIR：那东西就是酸。

But look at my uric acid level.

但是看看我的酸水平。

Less common kidney stones are made of calcium phosphate, or uric acid.

不太常见的肾结石是由磷酸钙或酸制成的。

Other nitrogenous wastes include uric acid and creatinine.

其他含氮废物包括酸和肌酐。

When the birds feed on tainted carcasses, uric acid crystallizes in their kidneys.

Urine contains compounds that consist of calcium, sodium, potassium, oxalate, uric acid, and phosphate.

液中含有由钙、钠、钾、草酸盐、酸和磷酸盐组成的化合物。

It happens when uric acid crystals form in the joints, causing them to swell.

Finally, there are some rare stones made of xanthine, which, just like uric acid, is a byproduct of purine breakdown.

最后，还有由黄嘌呤形成的罕见结石，同酸一样，是嘌呤分解的副产物。

There are also medications that help to decrease uric acid levels, which include xanthine oxidase inhibitors like allopurinol.

也有一些药物可以帮助降低酸含量，包括黄嘌呤氧化酶抑制剂，如别嘌醇。

Uricosuric medications, like probenecid, increase excretion of uric acid by the kidneys.

促酸排泄药物，如丙磺舒，会提高酸的肾脏排泄。

Since uric acid is a breakdown product of purines, a very common reason for high levels of uric acid is consuming lots of purines.

由于酸是嘌呤的分解产物，故高酸是大量摄入嘌呤的结果。

The most common type of stones are calcium oxalate stones, though other types include uric acid stones and struvite stones.

草酸钙结石是最常见的类型，其他类型的结石有酸结石和感染性结石。

Xanthine oxidase is an enzyme involved in the breakdown of purines to uric acid, so inhibiting this enzyme results in less uric acid production.

黄嘌呤氧化酶负责分解嘌呤为酸，所以抑制这个酶，就可以减少酸的生成。

Also, some individuals have a genetic predisposition to overproduction of uric acid while others with chronic kidney disease may be unable to excrete the uric acid.

同，某些个体遗传易感，倾向于过量生成酸；而慢性肾病病人因其无法正常排泄酸，也可能诱发痛风。

High levels of uric acid can also cause gouty arthritis, most commonly in the first metatarsal joint which is the base of the big toe.

高酸会导致痛风性关节炎，最常发生于第一跖骨关节即拇趾的基底部。
