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的醛固酮，一种类似于肾的物质，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，某人产生了太醛固酮的情况下，比如原发性醛固酮增症，的钾被主细胞分泌并排泄，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.

这会刺醛固酮的释放，醛固酮让肾脏保留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.

醛固酮增症的治疗通常使用保钾利尿剂，尤其是螺内酯：其可竞争性结合主细胞及α-闰细胞上的醛固酮受体。

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

醛固酮的另一面，有一组利钠，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，因为它不仅能肾脏中，还能唾液腺、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.

原发性醛固酮增症中，主要问题是球状带细胞分泌高水平的醛固酮；醛固酮对肾有负反馈作用，因而实际上抑制肾生成。

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.

醛固酮的作用下，离子泵使得的钠离子进入血中，的钾离子进入细胞中，提升细胞内钾离子浓度。

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，例如肾抑制剂、ACE抑制剂、血管紧张II受体拮抗剂、选择性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.

最常见的原发性病因称为特发性醛固酮增症：这是由于球状带分泌醛固酮的细胞数量增加，但目前尚不清楚为什会发生这种情况。

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分泌的重要醛固酮。

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.

醛固酮属于一特定家族或轴的一部分，这些共同作用，被称为肾-血管紧张-醛固酮系统。

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

醛固酮增症的诊断主要通过测定肾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胞内壁钠通道和钾通道的数量和主细胞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.

它增加主细胞腔面钠离子、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.

醛固酮增症的继发性原因通常是由于高水平肾导致醛固酮生成过。

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。
