胸腺

Since its discovery, vitamin A has been shown to be pivotal in several bodily functions: formation of "visual purple" which allows us to see partially in low light; maintenance of healthy vision and proper eye function; repair and maintenance of epithelial tissues, especially those of the skin and mucous membranes; maintenance of the endocrine system, especially the thyroid gland; proper utilization of dietary proteins; and stimulation of the thymus gland, a major part of the immune system.

由于其发现，维生素A已被证明可在几个举足轻重的身体机能：形成"视觉紫色"让我们看到部分在光线较暗的；维护健康的理想和正确的眼睛功能；修理和保养上皮组织，尤其是那些对皮肤和粘膜膜；保养内分泌系统，特别是甲状腺；适当利用膳食蛋白质类；和刺激胸腺，一个主要部分免疫系统。

Seven compounds have been isolated from hard coral Acropora pulchra. These compounds are:pentadecoic acid, heptadecyl ester;(2)n-cetanol;(3)batyl alcohol;(4) N- [ 1 --2-hydroxyl--3,7-heptad-ecadienal] -hexadecanamide;(5)1 -0-hexanoyl-glycerol ester;(6)thymine;(7)uracil. Their structures were determined by IR, MS, HNMR, 13CNMR analysis.

从北海佳丽鹿角珊瑚Acropora pulchra乙醇提取液的乙酸乙酯部分分离出七个化合物，经IR、MS、~1HNMR、~(13)CNMR等波谱方法鉴定，其结构分别为：(1)十五酸十七酯，(2)正十六碳醇，(3)鲨肝醇，(4)N-1-羟基甲基-2-羟基—-3，7-十七碳二烯基十六酸酰胺，(5)1-正十六酸甘油酯，(6)胸腺嘧啶，(7)尿嘧啶。

Four rats of either group were sacrificed at the day of 2,4,6,8,10, separately; the level of blood glucose and the contents of adrenocorticotropic hormone,orticosterone and adrenaline were measured as the stress markers,as well as the relative weight of the thymus and spleen.

于第2、4、6、8和10天分批处死大鼠，检测应激指标血糖、促肾上腺皮质激素、皮质类固醇、肾上腺素含量，测量胸腺和脾脏重量与体重的相对比值。

Methods: the first experiment Immunetolerance in mice sciatic nerve allograft by intrathymic injection of allogene: 48 mice were divided into 4 groups randomly: Group A,Group B, Group C and Group D(nerve allograft under immunosurppressant).

研究技术路线：第一部分：小鼠胸腺内注射异基因抗原在同种异体坐骨神经移植免疫耐受中的作用 1、动物分组：48只Balb／c小鼠随机分为4组，A组；B组；C组；D组(异体神经移植加用免疫抑制剂组)。

Objectives:(1) to introduce immunetolerance in mice sciatic nerve allograft by intrathymic injection of allogene.(2) to compare the effect of fresh sciatic nerve allotransplantion and cold preserved sciatic nerve allotransplantation with different diameter.

研究目的：(1)探讨小鼠胸腺内注射异基因抗原在同种异体异基因坐骨神经移植免疫耐受中的作用；(2)比较不同直径的新鲜自体神经和冷冻异体神经移植的效果，探讨神经直径对神经移植效果的影响。

OBJECTIVE: To observe the effects of intrathymic injection of allogenic antigen on inducing immunological tolerance in nerve transplantation.

目的：观察胸腺内注射异基因抗原在同种异基因神经移植免疫耐受中的作用。

Objective:To study the expression and significance of Tbet in thymus of Immunemediated aplastic anemiamice.

目的：探讨再生障碍性贫血小鼠模型中Tbet蛋白在胸腺的表达水平和意义。

Progesterone increased the formation of the CDK2-p21 and CDK2-p27 complexes, but not the CDK4-p21 and CDK4-p27 complexes. Moreover, the assayable CDK2, but not CDK4, activity was concentration-dependently decreased by progesterone treatment.

藉由同时给予p21与p27反义寡核苷酸造成p21与p27的表现被抑制，会回复助孕酮所产生之胸腺嘧啶核甘标记嵌合([3H]thymidine incorporation)的抑制。

METHODS AND RESULTS: Human smooth muscle cell and fibroblast cell sheets were harvested from temperature-responsive culture dishes and transplanted into ischemic hind limbs of athymic rats.

方法和结果：人类平滑肌细胞和成纤维细胞从温度敏感的培养皿中获得移植到无胸腺鼠的缺血下肢。

There were no cells on the SIS as control. They were implanted subcutaneously in the dorsa of the athymic mice. The implants were harvested after in vivo incubation for 4, 8 and 12 weeks.

将复合培养细胞与单纯材料分别植入无胸腺裸鼠皮下，扫描和透射电镜观察植入前和植入后4、8、12周成骨细胞、血管生成的变化过程。

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。
