The effects of zinc (Zn2+) and ethylenediaminetetra-acetic acid (EDTA) on tissue cadmium (Cd2+) were investigated in the smooth muscles of rabbit trachea, taenia coli, aorta and guinea-pig taenia coli. 2. After an Cd uptake in high-K2+ solution, samples were rinsed with cold high-K2+, cold Zn2+ or cold EDTA solution without Cd2+ and the results were quantitatively different from each other. 3. Concentration-response curves were obtained with each treatment of cold solution. 4. It is suggested that tissue Cd2+ can be divided into 3 fractions in the surface membrane and there is another fraction in cellular space.

在兔气管、结肠带、主动脉平滑肌以及豚鼠结肠带中研究了锌（Zn2+）和乙二胺四乙酸（EDTA）对组织镉（Cd2+）的影响。2. 在高钾溶液中摄取镉后，将样本用不含Cd2+的冷高钾溶液、冷Zn2+溶液或冷EDTA溶液冲洗，结果彼此在数量上有所不同。3. 对每种冷溶液处理都获得了浓度-反应曲线。4. 提示组织Cd2+在表面膜中可分为3个部分，在细胞间隙中还有另一部分。
