They had higher SCE rate and micro nuclei rate, with 14.12times per cell, and 13.28 times per cell, respectively for SCE rate and 25.2% and 21.2%, respectively for micro nuclei rate, After treated wito mitomytin, they had even higher SCE (38.3、37.2)and micro-nuclei rate(10.7%,10.2%) than normal β－lymphoblast cell line.

现常用细胞EB病毒体外感染外周血淋巴细胞建立淋巴母细胞株，具永生性和不致瘤性，保持原有细胞的生物学特性，为实验室研究提供可信的材料[2]。

Decidual tissue is a very complex and highly concordant tiny environment between mother and embryo during pregnancy, which is constituted of the variety cells such as extravi11ous trophoblast,endometrium cells, bone marrow cells, decidua l microphage,T cells and a few B cells and so on.

正常蜕膜组织是母-胎界面间一个非常复杂而又高度协调的微环境，它由多种细胞如侵袭至蜕膜的绒毛外滋养细胞(extravi11ous trophoblast，EVT)、子宫内膜源性细胞(如上皮细胞和血管内皮细胞)、骨髓源性细胞(如大颗粒淋巴细胞、蜕膜巨噬细胞、T细胞和少许B细胞)构成，这些细胞以及由这些细胞、母体和胎儿所分泌到蜕膜的细胞因子共同形成了母-胎间信息交流的平台，并对胚胎滋养细胞"有控性"侵袭、子宫内膜的免疫容受性、蜕膜化和胎盘的形成进行精细的调控。

24H treatment group compared with 24h model group: the level of MCP-1 of the Gardenoside group decreased, but the level of MIP-1 of it is no different with the model group; the level of the MCP-1 of the Baicalin group increase and the level of MIP-1 of it all decreased; the level of MCP-1 and MIP-1 of the Concha Margatitifera Usta all decreased; the level of MCP-1 of the Cholic Acid group decreased and the level of MIP-1 is no different with the model group; the level of MCP-1 and MIP-lof the Hefang Group decreased than the model group.

在本实验中，脑缺血能够诱导P53蛋白表达，P53蛋白可能参与调控缺血后神经细胞延迟性死亡的病理生理过程，药物通过抑制细胞凋亡，从而发挥治疗作用。五、大鼠局灶性脑缺血12小时模型组缺血脑组织HSP70光密度值含量较正常组明显增高（p＜0.05）。珍珠母治疗脑缺血12小时组缺血脑组织HSP70光密度值较缺血12小时模型组无显著性差异（p＞0.05）。胆酸治疗脑缺血12小时组缺血脑组织HSP70光密度值较缺血12小时模型组无显著性差异（p＞0.05）。

In summer of the result of the experiment, we can suspect the traditional Chinese medicine BaoTai Decoction may urge Th2 cytokine (IL-4, IL-10)'s express level to increase and Th1 cytokine (IL-12, IFN-γ)'s express level to decrease through adjusting Th cell's network equibrium, then prohibit maternal -fetal immune system to assault Fetus, which is good to maintenancing cyesis.

综合本实验结果，推测中药保胎汤可能通过双相性调节母-胎界面Th细胞网络的平衡，促使保护母-胎免疫功能Th2型细胞因子（IL-4，IL-10）增加，损伤母-胎免疫Th1型细胞因子（IL-12，IFN-γ）抑制，从而阻止母胎免疫系统对胎儿的攻击，利于妊娠维持。

IDO inhibits the proliferation of eukaryotic intracellular pathogens or tumor cells by depriving them of tryptophan. IDO has been targeted for neurological disorders: it causes decrease of serotonin level in the brain resulting depression, and it causes the accumulation of neurotoxic quinolinic acid. IDO plays a key role in the suppression of T cell response and antitumor immune, it induces immune tolerance to embryo and explant.

IDO可通过降低微环境中色氨酸的浓度而达到抑制病原微生物增殖的作用； IDO与神经系统疾病也密切相关，它能降低5-羟色胺的水平而导致抑郁，也可造成脑中喹啉酸等具有神经毒性的代谢产物的累积； IDO在抑制T细胞免疫和抗肿瘤免疫、诱导母胎免疫耐受和移植物免疫耐受中均发挥重要的代谢性免疫调节作用。

A cerebellar tumor like this, occurring in a 21 year old, generates a list of differential diagnosis that includes medulloblastoma (anaplastic or large cell variant), atyical rhabdoid/teratoid tumor, and less likely, choroid plexus carcinoma and metastasis.

发生于21岁男性小脑类似这样的病变，需要跟多种肿瘤鉴别，包括髓母细胞瘤，不典型畸胎瘤样/横纹肌样瘤，脉络丛癌以及转移性肿瘤等。

For the Batrachuperus tibetanus, the follicle cells are the main sites for e2, P and T, but the thecal cells are not shown to product steroid.

说明，在卵母细胞发育中，有尾两栖类和无尾两栖类性类固醇激素的作用有一些差异。

For further studying the genetic mechanism of the reproductive isolation phenomenon of interspecific hybrid, paraffin sections of testes from 13 sexually mature male mules (Equus asinus×Equus caballus) and 12 hinnies (Equus caballus×Equus asinus) were prepared, and the samples of Giemsa meiosis and AgNO 3 synaptonemal complexes were observed and compared with spermatocyte meiosis of horse and donkey under light microscope and electronic microscope.

为了进一步探讨种间杂种生殖隔离现象的遗传机理，本研究采用性成熟公骡的睾丸为材料，制备组织切片和减数分裂联会复合体标本进行观察，发现个别性腺发育较好的个体虽然减数分裂存在大量异常，但确有少数精母细胞完成了减数分裂并产生精子。
