Prosthet Dent.-1988,59(5).-587～589试验对象是19岁～61岁的22名患者(男性12名,女性10名)。在试验前和藏入银钯合金修复体后5天～7天。按Mancini 的放射免疫扩散法测定患者的血清IgA、IgG 和IgM 的水平。结果为戴入修复体后,所有患者的血清IgA、IgG和IgM 水平都有轻微上升(P>0.1)。口腔内原存在其它牙科合金的患者的血清免疫球蛋白的平均值下降(P>0.1),但从前口内没有存在其它合金的患者的 Prosthet Dent.-1988,59 (5) .- 587-589 The subjects were 22 patients (12 males and 10 females) aged 19 to 61 years. 5 days ~ 7 days before the test and after hiding in the silver-palladium alloy restoration. Patients' serum IgA, IgG and IgM levels were determined by Mancini's radioimmunodiffusion assay. As a result, serum IgA, IgG, and IgM levels increased slightly (P> 0.1) in all patients after wearing the prosthesis. The mean serum immunoglobulin in patients with other dental alloys in the oral cavity decreased (P> 0.1), but in the absence of other alloys in the anterior oral cavity
