Solubility of metal components into tissue culture medium, YLH, from various dental amalgams including high copper, conventional and copper amalgam was measured with atomic absorption spectrometry. The results obtained were as follows.: 1. Mercury solubility was found much in all the dental amalgams after one day extraction. This was followed by gradual increase in solubility in the high copper amalgams until after seven days. On the otherhand, initial high solubility was maintained in conventional and copper amalgams through the whole experimental period. 2. Higher solubility of silver and copper was recorded in the high copper amalgams. 3. Zinc was only found in Dispersalloy and copper amalgam. 4. Tin was unable to be measured in all the amalgams examined. It was considered that the present results could shed a light on the mechanism for cytotoxicity yielding of the dental amalgams.
利用原子吸收光谱法测定了包括高铜、传统和铜汞合金在内的各种牙科汞合金中金属成分在组织培养基YLH中的溶解度。得到的结果如下：1. 在一天的萃取后，所有牙科汞合金中都发现有大量汞溶解。随后，高铜汞合金中的溶解度逐渐增加，直至七天后。另一方面，传统和铜汞合金在整个实验期间都保持着最初的高溶解度。2. 在高铜汞合金中记录到银和铜的溶解度更高。3. 仅在Dispersalloy和铜汞合金中发现了锌。4. 在所有检测的汞合金中均无法检测到锡。据认为，目前的结果可能有助于阐明牙科汞合金产生细胞毒性的机制。
