Another example is a tumor that produces excess aldosterone, which just like renin, leads to fluid retention.

另一个例子是肿瘤的生长也会产生过多的醛固酮，一种类似于肾素的物质，会导致液体的积存。

All that being said, in situations where somebody produces too much aldosterone, like primary hyperaldosteronism, then there's more potassium secretion by the principal cells and excreted, and therefore less potassium is retained, leading to hypokalemia.

说了这么多，在某人产生了太多醛固酮的情况下，比如原发醛固酮增多症，多的钾被主细并排泄，这意味着少的钾被保留，导致了低钾血症。

This stimulates the release of aldosterone, which tries to bring blood pressure back up by telling the kidneys to retain more sodium and water.

这会刺激醛固酮的释放，醛固酮让肾脏保留多的钠和水来尽量维持血压。

Treatment of hyperaldosteronism is usually with potassium-sparing diuretics, especially spironolactone, which competitively binds to aldosterone receptors on the principal and alpha-intercalated cells.

醛固酮增多症的治疗通常使用保钾利尿剂，尤其是螺内酯：其可结合主细及α-闰细上的醛固酮受体。

On the flip side of aldosterone, there is a group of hormones called natriuretic hormones, i. e. sodium urinating hormones.

在醛固酮的另一面，有一组激素叫利钠激素，也就是钠尿荷尔蒙。

Aldosterone is important because its job is to hold on to sodium by conserving it not only in the kidney, but also in the salivary glands, sweat glands, and colon.

醛固酮很重要，因为它不仅能在肾脏中，还能在唾液腺、汗腺及结肠中固钠。

In primary hyperaldosteronism, the main problem is that zona glomerulosa cells secrete high levels of aldosterone, and that aldosterone has a negative feedback effect on renin, and so it actually inhibits renin production.

在原发醛固酮增多症中，主要问题是球状带细高水平的醛固酮；醛固酮对肾素有负反馈作用，因而实际上抑制肾素生成。

As the pumps collectively move more sodium into the blood under the influence of aldosterone, more potassium gets pumped into the cell, which raises the intracellular potassium concentration.

在醛固酮的作用下，离子泵使得多的钠离子进入血中，多的钾离子进入细中，提升细内钾离子浓度。

Along the same lines, drugs that reduce the effect of aldosterone can also cause hyperkalemia, and these are drugs like renin inhibitors, ACE inhibitors, angiotensin II receptor antagonists, selective aldosterone blockers, and potassium-sparing diuretics.

同理，可以降低醛固酮效能的药物也可以导致高钾血症，例如肾素抑制剂、ACE抑制剂、血管紧张素II受体拮抗剂、选择醛固酮受体阻滞剂以及保钾利尿剂等。

The most common primary cause is called idiopathic hyperaldosteronism, because the zona glomerulosa has an increase in the number of cells secreting aldosterone, but it's not really clear why this happens.

最常见的原发病因称为特发醛固酮增多症：这是由于球状带醛固酮的细数量增加，但目前尚不清楚为什么会发生这种情况。

Another study shows that when salt intake drops below 1.5 teaspoons per day, a significant increase in renin and aldosterone occurs.

另一项研究显示，当盐摄入量降至每天 1.5 茶匙以下，人体中的醛固酮及肾素水平将大幅上升。

An important hormone that helps regulate potassium reabsorption or secretion in the kidneys is aldosterone.

肾脏中一种帮助调节钾重吸收或的重要激素叫醛固酮。

These drugs inhibit Angiotensin Converting Enzyme, hindering an important step in the RAA system resulting in lower aldosterone and lower blood pressure.

这种药物通过抑制血管紧张素转化酶的作用（RAA 系统的关键作用之一），以达到降低醛固酮水平及血压的目的。

Aldosterone is part of a hormone family or axis which work together and are called the renin-angiotensin-aldosterone system.

醛固酮属于一特定激素家族或激素轴的一部，这些激素共同作用，被称为肾素-血管紧张素-醛固酮系统。

The diagnosis of hyperaldosteronism is mainly done by measuring levels of renin and aldosterone.

醛固酮增多症的诊断主要通过测定肾素与醛固酮的水平来完成。

Aldosterone increases the number of sodium channels and the number of potassium channels on the lumen side of the principal cell as well as sodium-potassium pumps on the basolateral side of the principal cells.

醛固酮可以增加主细内壁钠通道和钾通道的数量和主细外壁钠钾离子泵的数量。

Aldosterone has it's purpose, but it's not a hormone you want to regularly have high levels of.

醛固酮有其作用，但在人体中，这种荷尔蒙的水平不能太高。

Aldosterone increases sodium channels on the lumen side of the principal cell and sodium-potassium pumps on the basolateral side of the principal cells.

它增加主细腔面钠离子、钾离子通道和基底面的钠-钾泵的数量。

Secondary causes of hyperaldosteronism are usually due to excess aldosterone production in response to high levels of renin.

醛固酮增多症的继发原因通常是由于高水平肾素导致醛固酮生成过多。

But, as I mentioned earlier, this renin angiotensin aldosterone system is stimulated by low salt intake.

但是，正如我之前提到的，低盐饮食会导致 RAA 系统活跃。
