Abstract

Renal clearance of endogenous 5-HIAA has been shown to be similar to that of PAH in humans. The present study compared 5-HIAA and PAH clearances in rats. It showed that the clearance of 5-HIAA in rats was identical to that of inulin and creatinine. This suggests that in this species, 5-HIAA is only filtered and not secreted by the tubules in contrast to what is observed in humans.

摘要

内源性5-羟吲哚乙酸(5-HIAA)的肾清除率在人体中已被证明与对氨基马尿酸(PAH)相似。本研究比较了大鼠体内5-HIAA和PAH的清除率。结果显示,大鼠体内5-HIAA的清除率与菊粉和肌酐的清除率相同。这表明,与在人体中观察到的情况相反,在该物种中,5-HIAA仅通过肾小球滤过,而不被肾小管分泌。
