胸腺

Results There were 19 cases of thymoma, 6 cases of thymolipoma, 1 case of thymic carcinoma.

结果：胸腺瘤19例，胸腺脂肪瘤6例，胸腺鳞癌1例。

The biological behavior of thymoma with or without capsule might not be assessment standard for benign or malignancy.

有包膜的胸腺瘤和无包膜的胸腺瘤的生物学行为不是判断胸腺瘤良恶性的最佳指标。

The hepatocytes which were injected into thymus could survive more than 2 weeks after injection and appeared to be irregular hepatic cells cords and sinusoid in shape, and severe vacuolar degeneration in 3 weeks.

本实验在未用任何免疫抑制剂的情况下，肝细胞胸腺内注入后1周、2周，显微镜下见植入胸腺内的肝细胞已生长出不规则的肝索及肝窦样结构。3周时的胸腺内植入的肝细胞仍存活，但空泡变性明显。

There were 35% patients with thymomas, and the thymomas were excised.

有35 %的病人合并有胸腺瘤、胸腺增生，行胸腺切除术。

We compared the difference of gene expression between thymus in one-and ten-month old Balb/c micee using DDRT-PCR. It was found that there would be a significant difference of gene expressions in murine thymuses.

我们采用差异显示反转录PCR技术对1月和10月龄Balb／c小鼠胸腺mRNA的差异表达情况进行了分析，共获得月龄差异表达的cDNA片段108条（其中90条源于1月龄小鼠胸腺中，而有18条源于10月龄小鼠胸腺中）。

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。

RESULTS The results indicated that PCF could significantly increase the viability of thymocytes and enhance the activities of SOD, GSH-Px, CAT in cells. PCF decreased the amounts of ROS and the rate of apoptosis in cells. PCF inhibited the morpholog alteration of the thymocytes irradiated by UVB and maintained the ultrastructure of cells in normal. PCF attenuated UVB caused DNA fragmentation in thymocytes. While combined ERKs inhibitor yielded typical DNA fragmentation, co-treatment of thymocytes with PCF and JNKs and p38 kinase inhibitors completely blocked UVB-induced DNA fragmentation.

结果 PCF能显著提高UVB辐射后小鼠胸腺淋巴细胞的活性；提高胞浆中SOD、GSH-px、CAT的活性，降低ROS含量及细胞凋亡率；抑制UVB辐射所致的胸腺淋巴细胞凋亡的形态学改变，维持细胞的正常超微结构；抑制UVB所致的胸腺淋巴细胞DNA片段的出现；预先应用ERK抑制剂使DNA片段增加，给予JNK和P38抑制剂后协同PCF使DNA片段带减少。

The numbers of ANAE(superscript +) T cells in the spleen and head kidney were more than those of thymus, therefore, it is suggested that the matured T cells are emigrated thymus to spleen and head kidney.

实验结果进一步证明了胸腺中的T细胞多为不成熟的T细胞，此外，还含有大量的IgM细胞；而脾脏、头肾内的ANAE T细胞多于胸腺，推测胸腺成熟的T淋巴细胞迁移到头肾和脾脏。

Methods The genomic DNA was extracted from murine thymocytes and splenocytes for PCR amplification of the target fragments.

推测其中的初始T细胞的数目，评价胸腺功能，从而为胸腺功能研究及胸腺研究模型的建立提供研究依据和方法。

Results Average weights ofthe thymi and adrenal glands were45.38±14.13g and4.75±1.65g respectiveˉly;There were8adrenal gland atrophy cases and4lymph tissue hyperplasia cases in8decedents.

结果 胸腺肥大猝死者平均胸腺重45.38±14.13g，双侧肾上腺重4.75±1.65g，8例胸腺肥大猝死者肾上腺均发生不同程度萎缩、皮质细胞减少；4例伴有淋巴组织增生。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
