The renal clearance of amino acids in canine pups 5 days and 3, 8, and 12 weeks of age was studied. The 5-day-old pups had incomplete reabsorption of most amino acids. At 3 weeks, fractional reabsorption of 16 of 21 amino acids was complete; between 3 and 8 weeks, an adult pattern of reabsorption was present. Seemingly, a rapid development of amino acid transport precedes anatomic development or functional maturation of other transport systems.
对5日龄以及3周龄、8周龄和12周龄犬幼崽的氨基酸肾清除率进行了研究。5日龄的幼崽对大多数氨基酸的重吸收不完全。在3周龄时，21种氨基酸中有16种的重吸收率达到完全；在3至8周龄之间，出现了成年动物的重吸收模式。氨基酸转运的快速发育似乎先于其他转运系统的解剖学发育或功能成熟。
