胸腺组蛋白

Methods 40 ICR mice were divided into four groups: the control,the low(0.5 mg /kg),the middle(4 mg/kg) and the high(20 mg/kg),intragastric through mouth for 21 d,detected the thymocyte apoptosis by flow cytometry,observed the fas protein expression in thymus by immunohistochemistry.

方法ICR种小鼠体重20~25 g，雄、雌各半，共40只，随机分为4组，每组10只，即1个对照组和低、中和高3个组，经口灌胃21 d，流式细胞仪检测胸腺细胞凋亡状况，免疫组化染色，观察Fas蛋白在胸腺的表达。

MethodsThe transplanted tumor model of the mouse S180 sarcoma was established.Fifty mice were randomly divided into five groups,the control group,the CTX group,the Gecko group.They were treated respectively with oral administration of saline,and intraperitoneal injection of CTX 100 mg/kg only one time,oral administration of Gecko in doses of 13.5,9,4.5 g/kg,one time a day.After 14 days,the anti-tumor activity was evaluated by tumor tissue weighing. The impact on immune organ was detected by accounting thymus index, spleen index and the number of peritoneal macrophage which phagocytose chicken red blood cells.The protein express of vascular endothelin growth factor and basic fibroblast growth factor were detected by SABC immunohistochemistry.

方法建立移植瘤小鼠S180肉瘤模型，将50只雌鼠随机分为对照组、环磷酰胺组、壁虎高组、中组、低组共5组，分别给于生理盐水灌胃1次/d，CTX（100 mg/kg）腹腔注射1次，壁虎高、中、低组（13.5，9，4.5 g/kg），每天灌胃1次。14 d后，称取荷瘤小鼠瘤重、胸腺重、脾脏重，计算抑瘤率、胸腺指数、脾脏指数，观察腹腔巨噬细胞吞噬鸡血红细胞实验指标；用SABC免疫组化法检测血管内皮生长因子、碱性成纤维细胞生长因子的蛋白表达，TUNEL方法检测细胞凋亡率。

METHODS: Orthotopic liver transplantation was used in this study. Group Ⅰ: syngenic control (Wistar-to-Wistar); Group Ⅱ: acute rejection (SD-to-Wistar); Group Ⅲ: thymus inoculation of SD rat LSA day 7 before transplantation.

实验为同种肝移植：Ⅰ组为Wistar→Wistar同基因对照组；Ⅱ组为SD→Wistar急性排斥组；Ⅲ组为SD→Wistar术前1周供体肝特异性蛋白受体胸腺内注射处理组。

There were no difference between ZS rats and ZA〓 rats.

补锌后，p56〓蛋白的表达下降，ZS组大鼠胸腺和脾脏组织的阳性细胞率和ZA〓组无显著差异。

The group of mixture dieted albumin polypeptide with 3H-TdR was compared with the groupdieted only 3H-TdR in mice.

应用同位素示踪法对小鼠小肠、肝及胸腺等组织的3H-胸腺嘧啶核苷(3H-TdR)放射性值进行检测，比较了白蛋白多肽和3H-TdR混合物进食组小鼠与仅进食3H-TdR组小鼠间的区别。

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。

With the methods of Reverse transcription-PCR and cDNA sequencing, the expression of FHIT gene was detected in radiation carcinogenesis. The results show that: 1, The FHIT gene's sequence in normal BALB/c mice compare with the sequence of mice in Ge neBank which absents exon 3, but the function of FHIT protien doesn't alter.

结果发现：1、正常BALB／c 小鼠的FHIT基因序列同GeneBank中小鼠的FHIT基因序列比较缺少了外显子 3，但其表达的蛋白功能并未发生改变；2、FHIT基因在辐射损伤与辐射致癌的早期过程中，对照组血液、胸腺及骨髓均未出现异常的FHIT转录本的表达，不同剂量照射组中血液、胸腺及骨髓均有部分样品出现分子量较小的异常FHIT 转录本的表达。

General condition, haematology and biochemical tests, electrocardiogram, urine test, visceral dissection and coefficient and histopathology were performed.

结果： 给药期高剂量组的犬间断性出现呕吐，且摄食量减少，血清总胆红素明显升高，白蛋白降低，胸腺和脾脏的系数值有一定升高。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
