为控制汞合金的毒性,发是了一种新的汞合金:加入对汞毒性具有拮抗作用的硒(Selen)。本文就新汞合金的细胞毒性及各种机械性质与不加硒的汞合金进行了比较:(1)在传统常用的市售银锡合金中按重量加入0.2～1.0%的硒粉末的五种新汞合金分别按1∶0.75的比例进行机器调合,每一种汞合金制成三个直径3.27 0.03mm,长5.30.10mm的圆柱形试片,浸泡于最低需要量的1ml无血清Eagle培基内,37℃,15rph,48小时。离心使
To control the toxicity of amalgam, hair is a new amalgam: adding selen with an antagonistic effect on mercury toxicity. In this paper, the amalgam cytotoxicity and a variety of mechanical properties and without selenium amalgam were compared: (1) in the commonly used commercially available silver-tin alloy by weight of 0.2 to 1.0% of the five kinds of selenium powder The new amalgams were machine tuned at a ratio of 1: 0.75, each made of three cylindrical test specimens 3.27 0.03 mm in diameter and 5.30.10 mm in length, soaked in a minimum amount of 1 ml of serum-free Eagle's medium Base, 37 ° C, 15 rph, 48 hours.
