胸腺小体

肉鸡和蛋鸡胸腺小体大小的变化趋势基本相同。

The diameter of thymic corpuscle of broilers and layers was basically the same trend .

试验组胸腺小叶皮质增厚，淋巴细胞密集，髓质比例减小，胸腺小体减少、减小。

The cortex of thymic lobule of experiment group incrassated and the lymphocyte became coarctate , the portion of thymic medulla decreased and thymic corpuscle decreased and dwindled .

到20～21d，在封闭的微血管周围，由数层网状细胞形成典型的胸腺小体。

Model thymus corpuscle consists of many reticulocyte until the 21st day .

胸腺小体在胸腺发育中的形态发生及其功能探讨

Morphogenesis and functional differentiation of thymic corpuscles during the development of fetal thymus

胸腺小体数量增多。

Thymus bldies prominently increased in quantity .

Ⅱ组鸡的胸腺小体体积小且数量少；

In group II , the volume of thymus corpuscles was small and the number of thymus corpuscles was few ;

Ⅴ型细胞仅存在于髓质，多见于胸腺小体中，含大量张力丝和角蛋白颗粒。

Type ⅴ cells occurred only in medulla , usually in thymic corpuscles , contained numerous tonofilaments and keratin granules .

胸腺小体呈圆形或椭圆形，由多层呈同心圆状排列的扁平形上皮网状细胞围成。

Thymic corpuscles are round or oval-shaped , concentric circles were shaped by the multi-storey flat with the surrounding epithelial reticular cells .

对胸腺小体的萎缩消失过程：小体集中、变性、多个融合、囊性变解体与钙化解体消失进行了讨论。

The process of corpuscle involution from atrophy to disappearance are as follows : concentration , degeneration , fusion , cystic disintegration and calcified disintegration .

本研究还发现上述药物对胸腺小体有保护作用。

In the study , we also found that the Chinese herbal medicines above were markedly effective in the prevention of thymus corpuscle of mice .

结果表明，低剂量（0.015mg/kg体重）Tα1可显著提高鸡免疫器官指数，可使胸腺髓质小体数和淋巴细胞数增加，皮质增宽；

The low dose of thymosin α 1 ( 0.015 mg / kg ) could increase significantly the immune organ indexes of chicken , increase the number of Hassalls corpuscles and lymphocytes within thymus medulla , and broaden the thymus cortex .

对于单次给药动物模型，腹腔注射不同浓度MLT后60min给予1GyX射线全身照射，12h后采用流式细胞术和荧光分光光度法分别检测胸腺细胞凋亡小体百分率和DNA裂解率的变化；

For single administration of MLT , the apoptotic body percentage ( ABP ) and DNA lytic rate ( DLR ) in the thymocytes were determined with flow cytometry and fluorospectrophotometry , respectively , 12 h after irradiation .

结果：死胎胸腺组织胸腺小体数量明显减少；

There were HBsAg in the thymus tissues .

胸腺萎缩，淋巴细胞与胸腺小体明显减少；

The thymus atrophied , the number of lymphocytes and thymic corpuscles decreased obviously .

试验组的胸腺小叶皮质增厚，胸腺小体增多；

In experiment group , the cortex of thymic lobule , bursa nodule and Periarterial Lymphatic Sheaths thicken obviously ;

随着胸腺发生意外性萎缩，胸腺小体形态可多样化。

With accidental thymic involution the shape of Hassal ′ s corpuscles might change .

在200g以上的成年鳖胸腺内发现有同心圆状胸腺小体。

Concentric thymic corpuscles were observed in thymus of mature Trionyx sinensis ( over 200g ) .

在各发育期中华鳖胸腺皮质、髓质交界处和髓质区有明显的囊状胸腺小体和交错突细胞。

During development period , there were cystoid thymic corpuscles and interdigitating cells in thymic medulla and cortico - medullary border .

在胸腺内有多种NADPH-d和nNOS阳性细胞，按其形态可分为：髓质上皮样细胞、胸腺树突样细胞、神经元样细胞、胸腺细胞样细胞及胸腺小体；

There were many kinds of NADPH d and nNOS positive cells in the rat thymus . These were epithelial like stromal cells , dendritic like cells , neuron like cells , medullary stromal cells and thymic corpuscle .
