钠和水代谢障碍是临床常见的变化,每天吃得咸的人摄入钠量可高达870毫当量(约相当于50克氯化钠)。而无盐饮食病人则最低可降至9毫当量,这样大的波动范围,通过肾脏对钠排泄的调节,仍能维持钠平衡。所以肾脏排钠的调节在维持正常钠平衡中占重要地位。目前有关这方面的调节机制已有比较深入的了 Sodium and water metabolism disorders are common clinical changes, and people who eat salty daily intake of sodium up to 870 milliequivalents (about the equivalent of 50 grams of sodium chloride). The salt-free diet patients can be reduced to a minimum of 9 milliequivalents, such a large range of fluctuations, through the regulation of renal sodium excretion, still maintain the balance of sodium. Therefore, the regulation of renal sodium in the maintenance of normal sodium balance plays an important role. The current regulatory mechanism in this area has been more in-depth
