The analysis of sister chromatid exchange frequencies is a useful tool for the study of damages in genetic material of human beings induced by enviromental mutagens and carcinogens.

用荧光加Giemsa术区分姐妹染色单体，分析了13名中年男子外周血淋巴细胞的SCE，比较吸烟者和不吸烟者"自发"的和用丝裂霉素诱发的SCE频率变化。发现吸烟者的SCE频率(8.33±1.08)显著地高于不吸烟者(4.41±0.72)，p.001。

Results In the very elderly, most of the DCs were nonviable at the 7th day after cultured, and no DCs were detected in 8 subjects.The capacity to stimulate proliferation of allogeneic T lymphocytes was also lower.On the other hand, in the elderly,the DCs grew prosperity in all the subjects. At the 7th day after cultured, DCs could be seen in the every subjects.

结果 ≥80岁组DCs培养过程中细胞逐渐死亡，培养至第7天大部分细胞死亡，获得的DCs数量较少，其中有8例未能培养出DCs；较60～70岁组对同种T淋巴细胞的刺激能力也显著下降，而60～70岁组培养细胞的活力保持较好，至第7天均可获得数量较多的DCs。

Mel coule promote the proliferation of PBL and prohibite the apoptosis of PBL from type 2 DM patients, and its effect varied with its concentration; Mel took its greatest influence at the pharmacological concentration, probably due to Mel could regulate the function of immune system and have effect of antioxidation.

Mel有促进2型DM患者外周血淋巴细胞的增殖反应并有效抑制其凋亡的作用，可能与Mel的免疫调节和抗氧化作用有关，为临床应用Mel作为2型DM的辅助用药奠定基础；4。

植物凝血素：任一种与细胞质膜上的特定碳水化合物结合的植物糖蛋白，在实验室中用来加速淋巴细胞的繁殖和红血细胞的凝结

NF-κB is a kind of important nuclear factors which are relative to lots of cellular activities such as activation of immunocyte, development of T and B lymphocyte, stress reaction, cell apoptosis and so on. NF-κB exists in almost all types of cytoplasm in the unreactive form of heterodimer or homodimer.

核转录因子κB(nuclear transcription factorκB， NF-κB)是一类关键性的核转录因子，通常以同源或异源二聚体非活性形式存在于几乎所有类型细胞的胞质，其与免疫细胞的活化，T，B淋巴细胞的发育，应激性反应，细胞凋亡等多种细胞活动有关。

Changes in IL-2/IL-2R system in 25 patients with thyrotoxic Graves disease and 20 eu-thyroids were investigated and compared with those of 15 normal controls. The thyrotoxic patients showed a high concentration of serum sIL-2R and a large amount of circulating IL-2R-α- cells but a decreased production of IL-2 by PBMC. However, these abnormalities had a tendency to become normal with improvement of the disease.

Graves病的发生是环境、遗传和免疫等多种因素综合作用的结果＊淋巴细胞的免疫调节异常是其中的一个重要原因，而白细胞介素-2（IL-2）及其受体在维持正常T细胞功能和兔疫调节方面发挥关键作用。

Thymosin 1（Tα1） is a acidic protein composed of 28 amino acid residues with isoelectric point 4.2 and molecular weight 3102.Its amino acid sequence is: N-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu -Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-C. T1 is a T-cell potentiating factor.

胸腺素α1（thymosin 1，Tα1）是由28个氨基酸组成的酸性多肽，等电点4.2，相对分子量3108，其氨基酸序列为：N-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-C[1，2]。Tα1具有多种免疫活性，可以促进T淋巴细胞的成熟和分化，促进成熟的T细胞、自然杀伤细胞分泌各种细胞因子如IL-2、INF-α等，同时也促使高亲和力白介素-2受体的生成[3-10]。

From the kinetic observations through the early developmental period of the foetuses, the maximum yield of CFU-C in the liver occurs at 4-5 months of gestation: during the first 5 months of gestation the percentage of ...

从胎肝发育的动态分析中可以看到，对于妊娠4—5个月的肝脏，其中CFU-C的产率与总量达到最高值；在妊娠5个月内，T-淋巴细胞的含量基本保持在1-2％左右。

ISHH showed that many positive particles were seen in plasma of many T cells surrounded the blood vessels during 5 dpi～30 dpi and also a little positive particles were seen in plasma of kupffer cell during these time.

原位杂交显示：着染部位主要出现在坏死灶或血管周围的成团或散在的淋巴细胞的胞浆内，少数出现在枯否氏细胞的胞浆内。

Purpose: The present study probes to access the effect on the proliferation and cytotoxicity of the tumor infiltrating lymphocytes induced by interleukin-12 and activated by dendritic cells loaded with tumor antigen and to evaluate the possibility that IL-12 and DC enhance the specific cytotoxic activity of TILs to tumor cells.

目的：研究白介素12(IL-12)和负载肿瘤抗原的树突状细胞对肝癌肿瘤浸润淋巴细胞的增殖和细胞毒作用的影响，探讨IL-12和DC增强TIL特异性杀伤肿瘤细胞的可能性。
