采用平衡透析法，测定了腐蚀后的Cu-Al和Co-Cr牙科铸造合金中Cu、Al、Co和Cr离子与人唾液及其两种凝胶色谱组分的结合能力。结果表明，铜和钴结合到人唾液，即0.045和0.027毫克/毫克蛋白质，分别。Cu的结合能力最强，结合容量也最大。Cu结合的饱和度未达到试验中使用的0.35 mg蛋白质/ml的限度，而Co在约0.2 mg蛋白质/ml时达到完全饱和。铬显示绝对没有结合到人类唾液，而AI离子没有通过透析膜。与通过合成制成的含有添加的唾液型蛋白质的溶液的结合相比，表明与人唾液的结合大约1个数量级，至少对于Cu离子。
Employing equilibrium dialysis, the binding abilities of Cu, AI, Co and Cr ions from corroded Cu-AI and Co-Cr dental casting alloys towards human saliva and two of its gel Chromatographic fractions were determined. Results indicate that both Cu and Co bind to human saliva i.e. 0.045 and 0.027 mg/mg protein, respectively. Besides possessing the largest binding ability, Cu also possessed the largest binding capacity. The saturation of Cu binding was not reached up to the limit of 0.35 mg protein/ml employed in the tests, while Co reached full saturation at about 0.2 mg protein/ml. Chromium showed absolutely no binding to human saliva while AI ions did not pass through the dialysis membranes. Compared to the binding with solutions that were synthetically made up to contain added salivary-type proteins, it is shown that the binding to human saliva is about 1 order of magnitude larger, at least for Cu ions.
