Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin, demineralized bone matrix were implanted into the muscle pouch of mice, at different times after implantation, the immunological, histological and alkaline phosphatase assay were conducted. The results revealed that all four kinds of allogeneic implants activated specific cellular and humoral immune responses, most notably in fresh bone group, the AAA, BMG and DBM inhibited the proliferation of the lymphocytes in vitro and BMG had the most powerful inhibiting action, allogeneic AAA, BMG and DBM might induce heterotopic osteogenesis in vivo, however, there were obvious difference in ALP and histomorphometry between allografts and isografts.

在小鼠肌肉内植入同种异体或同系新鲜骨、自消化抗原去除骨、骨基质明胶、脱钙骨基质，术后免疫学、碱性磷酸酶、组织学检查发现：4种同种异体植入物均可引发特异性细胞免疫反应和体液免疫反应，其中以新鲜骨移植引发的免疫反应最为显著；自消化抗原去除骨、骨基质明胶、脱钙骨基质在体外具有抑制淋巴细胞增殖的作用，骨基质明胶对淋巴细胞增殖的抑制作用最显著；同种异体与同系4种植入物在体内成骨活性有显著差异；自消化抗原去除骨、骨基质明胶、脱钙骨基质均有异位诱导成骨活性，其中骨基质明胶骨诱导活性最佳。

After curative gastrectomies, the expression level of CCR7 was increased and correlated with the TNM stage (P＜0.05). Conclusions The expression of CCR7 is down??

CCR7在胃癌患者外周血淋巴细胞中的表达与临床病理分期密切相关，Ⅰ、Ⅱ期患者外周血淋巴细胞中CCR7的表达率明显高于Ⅲ、Ⅳ期胃癌患者（P＜0.05）。

The responsibility of spleen lymphocytes from mice immunized for 3 weeks was better than that from mice immunized for 1 week.

The NPC tissue was all EBV-positive except for one sample, which was identified as keratinizing carcinoma, but the control samples were all negative for EBV infection, which was correlated with CD25 expression.

对照组选取鼻咽慢性炎症组织。结果 CD25淋巴细胞在鼻咽癌组织中比在鼻咽慢性炎症组织中的表达明显升高，差异具有显著性意义(P.001)，且在未分化癌中表达高于角化型癌和非角化型癌(P.05)。原位杂交显示EB病毒与CD25淋巴细胞高表达有关。

Blood samples were drawn at 30 minutes before and 0 minute, 12 hours, 24 hours, 36 hours and 48 hours after the race from 14 subjects' forearm veins. PHA and LPS were used for assessing lymphocyte proliferation; lyses of 51Cr labeled K562 target cells were used for assessing natural cytotoxicity. Results showed that the lymphocyte proliferation stimulated by PHA and LPS was decreased at least for 24 hours; the natural killer cytotoxicity is increased at 0 minute and decreased at least 48 hours after the race.

本研究以14位一般大学男生为研究对象，血液样本於14位受测者跑步前30分钟及跑步后0分、12小时、24小时、36小时与48小时於受测者前手臂静脉抽取，以PHA及LPS有丝分裂原刺激淋巴细胞，评估周边血液中淋巴细胞增殖功能；以自然杀手细胞分解51Cr标记之K562标的细胞释出51Cr之总量，评估自然杀手细胞毒杀活性。

However, there is growing evidence that B lymphocytes play a role in many T-lymphocyte–mediated diseases.

然而，越来越多的证据表明B淋巴细胞在T淋巴细胞参与调节的疾病中起一定的作用。

The earlier period medicined diet can accelerate the hyperplasy of Peyer's patch cell in the intestinal tract, improve the proportion of T-lymphocyte subsets, and eventually improve the immunity function of intestinal tract.

早期药膳饮食有利于肠道Peyer's结淋巴细胞的增生，并改善Peyer's结T淋巴细胞亚群的比例，从而改善烫伤大鼠肠道免疫功能。

Within three years following-up, 5 patients with NHL were survival, but one case of NHL died at the 2 months after auto-PBSCT, one patient suicided. From 4 cases received allo-PBSCT, one patiant with NHL was died at 79 days later, one patient with chronic lymphoblastic leukemia was surviving, another 2 cases of acute lymphoblastic leukemia were dead at 17 months and 54 days respectively after allo-PBSCT.

随访3年，5例NHL患者无病生存，1例NHL患者于移植后2个月死亡，1例自杀；4例接受异基因造血干细胞移植的患者中，1例非霍奇金淋巴瘤移植后79天死亡，1例慢性淋巴细胞白血病患者无病生存，2例急性淋巴细胞白血病患者分别于移植后第54天、第17个月死亡。

The thymuses, spleens, sera and anticoagulant blood were collected after the rats were killed, to carry out these works:(1) Zinc concentrations were analyzed by atomic absorption spectrophotometry;(2) Body weight and the weight of thymuses and spleens were measured, the organ index were calculated;(3) Changes in pathology of thymus and spleen were observed;(4) Using TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) method, the apoptosis of thmocytes and spleen lymphocytes was checked;(5) The expression of bcl-2、bax mRNA in thymus and spleen were detected by RT-PCR (reverse transcription polymerase chain reaction);(6) The expression of p56〓, a signal transduction protein in thymus and spleen were detected by immunohistochemistry;(7) Two-color cytofluorometric analysis was used to assess the expression of CD4, CD8, CD45RA and CD45RC in peripheral blood lymphocytes.

动物处死后留组织、抗凝血及血清，进行以下检测：(1)原子吸收法测血清锌浓度；(2)测胸腺、脾脏脏器重量并与大鼠体重比较，计算脏器指数；(3)HE染色对胸腺、脾脏进行病理观察；(4)原位末端标记法测胸腺、脾脏中淋巴细胞的自发凋亡，并通过图像分析进行比较；(5)逆转录聚合酶链式反应检测凋亡调控基因bcl-2、bax mRNA在免疫器官中的表达；(6)免疫组化方法检测信号转导蛋白p56〓在免疫器官中的表达；(7)流式细胞术分析外周血淋巴细胞中CD4+、CD8+、CD45RA+及CD45RC+CD4+、CD45RC-CD4+细胞的数量和比例。

To study the function of thyroid hormone receptors in osteoblasts and in bone, the nuclear extracts of TRs from human osteoblast-like cell line MG63 and rat calvaria were achieved, and the two main kinetic parameters of TRs, affinity constant and maximal binding capacity, were determined by radio-ligand binding assay and Scatchard plot.

其中MG63和骨组织中TRs的Ka值与文献报告的人类外周血淋巴细胞以及大鼠脑组织和肝脏中TRs的Ka值相比，差别显著，但与文献中其他成骨细胞系的Ka值相近，提示成骨细胞或骨组织中的TRs与THs的结合能力有可能确实低于淋巴细胞、脑组织或肝脏，从而使得THs在骨组织中的作用机制及效果可能有别于其他组织。
