(1) In our research,frequent expression of BSAP in H/RS cell of classical Hodgkins disease provides further evidence for its B-cell origin,and the expression of BSAP on H/RS cells also can be in favor of the identification of H/RS cells and can distinguish HL from ALCL.(2) Expression of BSAP is located in nucleoli of cells,while that of CD20 in membrane.

结果 (1)33例cHL中，30／33(90.91％)H／RS细胞和33／33(100％)背景淋巴细胞BSAP表达阳性，而H／RS细胞10／33(30.30％)CD20阳性，1／33(3.03％)CD45RO阳性，31／33(93.94％)CD30阳性，25／33(75.75％)CD15阳性；(2)33例HL石蜡刮片组织中有16例(48.48％)出现IgH基因重排阳性，显微切割的19管H／RS细胞有14管(73.68％)扩增阳性，而12管背景淋巴细胞有2管(16.67％)扩增阳性；(3)测序分析周新华第一军医大学病理学教研室获得了一段免疫球蛋白重链可变区的重排片断；（4）原位PCR结果发现杂交的阳性颗粒不仅出现在探针来源的同一病例也出现在不同病例的HillS细胞核上，同时在部分周围背景淋巴细胞核上也见到阳性颗粒。
