1·The immunocompetence and cell toxicity of the samples toward Tand B lymphocyte were determined.

并且测定了样品对T、B淋巴细胞的免疫活性和细胞毒性。

2·The amplification of CD19+ B lymphocyte was significantly higher than other blood cell lingeages (P<0.05).

CD19+ B淋巴细胞得到优势扩增，明显高于其他各系血细胞比例（P＜0.05）。

3·Methods: to read the related literatures then to review and comment the B lymphocyte development and BCR gene rearrangement.

方法：通过相关文献的阅读，综合评述B细胞发育与BCR基因重排。

4·Conclusion: B lymphocyte development and BCR gene rearrangement is an ordered sequence. However, a lot of events in this procedure are unclear.

结论：B细胞发育及BCR基因重排是一个密切相关的十分有序的过程，但仍有许多问题未弄清楚。

5·Objective To inquire the effects of cooking oil fumes on the immunologic function by determining T and B lymphocyte subtypes in peripheral blood of cooking workers.

目的：通过对饮食从业人员外周血T淋巴细胞亚群、B淋巴细胞数量分析来了解烹调烟雾对机体免疫功能的影响。

6·Natural killer cells, which are a class of lymphocyte distinct from t cells and B cells, destroy foreign cells (eg, neoplastic cells) even without prior sensitization.

自然杀伤细胞是一类与T细胞和B细胞不同的淋巴细胞，可在未被致敏的情况下破坏外来细胞(如肿瘤细胞)。

7·The changes of peripheral T lymphocyte subsets and decrease of NK cells, which lead to proliferation of B cells, may play an important role in the development of SLE.

淋巴细胞亚群的改变和NK细胞活性降低，导致B细胞功能亢进，产生多种自身抗体，在SLE的发病机理中起重要作用。

8·The NK cell is the third lymphocyte, except T, B cells and a kind of cell subgroup having a unique function.

NK细胞是除T、B细胞之外的第三类淋巴细胞，具有独特功能的细胞亚群。

9·While, monoclonal antibody against CD20 antigen on the membrane of B-cell NHLs and normal B-lymphocyte showed satisfactory curative effect in clinical treatment of NHL.

针对B淋巴瘤细胞和B淋巴细胞表面CD 20抗原的单克隆抗体治疗NHL取得了较好的效果。

10·Conclusion: There no diagnosis value of WBC and lymphocyte to infant diarrhea disease, but neutrophilic band form and B/N value are important for the infant diarrhea diagnosis.

结论：白细胞计数总数和淋巴细胞的增加对婴幼儿腹泻病的诊断意义不大，中性粒细胞杆状核细胞绝对数和B/N值确有重要价值。
