Abstract
Polyethylene glycol (PEG plus (14)C-PEG) was measured turbidimetrically and by liquid scintillation counting to compare the validities of these methods during the use of PEG as a volume indicator of intestinal perfusion studies in man. Use of (14)C-PEG results yielded similar estimates of water absorption or secretion. The simplicity of (14)C counting offers practical advantages to the use of (14)C-PEG as a nonabsorbable marker for perfusion studies in man.
摘要
采用比浊法和液体闪烁计数法对聚乙二醇（PEG加¹⁴C-PEG）进行测量，以比较这些方法在将PEG用作人体肠道灌注研究的容量指标时的有效性。使用¹⁴C-PEG的结果得出了相似的水吸收或分泌估计值。¹⁴C计数的简便性为将¹⁴C-PEG用作人体灌注研究的不可吸收标记物提供了实际优势。
