Taplin氏等于1956年提出体外测定含放射性碘之物质在肾脏流入、储积及排出,以表明肾脏的功能情况和两肾功能的差别。此方法后来被广泛应用,并以其补充静脉尿路造影所不能表现的功能情况。 由静脉注射小量同位素马尿酸制剂而绘成之肾图曲线,它最初骤升,表示富于制剂的血进入肾血管,而后曲线之缓慢上升为制剂分泌进入肾小管细胞及肾内尿液,最后曲线向下倾斜
Taplin’s equal to 1956 proposed in vitro determination of radioactive iodine-containing substances in the inflow, accumulation and excretion of the kidneys to indicate the function of the kidneys and renal function differences. This method was later widely used, and its complement of intravenous urography can not show the functional situation. A nephogram, drawn from intravenous injection of small amounts of isotopic hippurate, initially swells to indicate that the blood rich in the agent enters the renal blood vessels and then slowly rises to the level that the agent secretes into the renal tubular cells and the urine in the kidney, The last curve is tilted downwards
