Mercury uptake to taenia coli increased with an increase of the Hg2+ concentration (0.05-5 mmol/l). The Scatchard plots of mercury uptake showed that two qualitative Hg2+ binding sites (high and low affinity sites) exist in taenia coli. The Scatchard analysis of Hg2+ binding at 4 degrees C indicated a single class of binding site (high affinity binding site only). These results indicate that Hg2+ binds to high affinity binding sites of cell membrane and Hg2+ of low affinity binding sites may reflect intracellular accumulation in taenia coli.
随着Hg2+浓度（0.05 - 5 mmol/l）的增加，结肠带对汞的摄取量增加。汞摄取的Scatchard图表明，结肠带中存在两种性质的Hg2+结合位点（高亲和力和低亲和力位点）。4℃下Hg2+结合的Scatchard分析表明存在一类结合位点（仅高亲和力结合位点）。这些结果表明，Hg2+与细胞膜的高亲和力结合位点结合，低亲和力结合位点的Hg2+可能反映了结肠带中的细胞内积累。
