Objective:To testify the induction of allo -hypo-immuno-responsiveness by immature dendritic cellswith deficiency of costi mulators.

目的：证实缺少辅助刺激分子的未成熟树突细胞在体外诱导同种T细胞的低应答性。

摘 要 目的：证实缺少辅助刺激分子的未成熟树突细胞在体外诱导同种T细胞的低应答性。

Results The expression of Bag-1 protein both in ameloblast and odontoblast was inhibited in experimental group.

结果 实验组大鼠切牙釉基质形成紊乱，成釉细胞和成牙本质细胞Bal-1蛋白表达明显低于对照组，差异有显著性(P.01)。

Results It was demonstrated that β-TrCP expressed in oral epithelium, tooth bud, mesenchymal cell cytoplasm of ameloblast and edontoblast of different stage of tooth development.

结果β-TrCP在胚胎10.5、13.5、14.5、16.5、18.5d的小鼠牙胚上皮层与间充质层，以及出生后0、3、6d的小鼠成釉细胞与成牙本质细胞胞浆呈特征性表达。

Methylation of CpG islands in the promoters induces gene silencing. The multiple tumor suppressor gene P16, located at chromosome 9p21, regulating normal proliferation of cells with a functional unit constituting of p16, cyclin D1 and pRb together. Methylation of P16 gene has been detected in several lymphocytic and plasmacytic malignancies such as lymphoma, acute lymphocytic leukemia and multiple myeloma and shows relationships with the pathogenesis of these diseases. Application of demethylation agents or arsenical to refresh the gene functions will be expected to be a new treatment for hemopoietic malignancies.

基因启动子区CpG岛甲基化常导致基因沉默。P16基因是一定位于9p21的多种肿瘤抑制基因，通过pl6INK4Acyclin D1-PRb通路维持机体细胞的有序增殖。P16基因甲基化在淋巴瘤、急性淋巴细胞性白血病、多发性骨髓瘤等多种淋巴细胞浆细胞肿瘤中被检测到，并与疾病的发生、发展存在一定关系，应用甲基化抑制因子或砷剂去甲基化治疗，恢复基因功能可望成为血液恶性肿瘤治疗的一种新手段。

Cancer of ovarian and transparent cell is most constant tumour of as epithelial as the ovarian surface of confuse of interblend of tumour of cell of the former reproduction that send a gender sex, especially with yolk bursa tumour and asexuality cell tumour are differentiated harder.

梗概： 卵巢透明细胞癌是最常和原发性生殖细胞肿瘤相混淆的卵巢表面上皮性肿瘤，尤其和卵黄囊瘤和无性细胞瘤较难鉴别。

OBJECTIVE: To study the cellular activity of asparagine synthetase in different types of childhood acute lymphoblastic leukemia.

目的：不同类型急性淋巴细胞性白血病对左旋门冬酰胺酶敏感度不完全相同，由于LAsp活性水平与细胞内门冬酰胺合成酶活性负相关，因此研究不同类型ALL患儿白血病细胞内门冬酰胺合成酶活性水平分布情况，有助于临床治疗中合理使用LAsp。

The distribution of the asparagine synthetase activity demonstrated a polymorphism in either T-ALL or B-lymphoid lineage ALL patients.

但无论是在B细胞系列ALL患儿还是在TALL患儿中，肿瘤细胞内AS活性存在多态性分布。

Protect integrity of lysosome in hairy cells of the cochlea, and prevent from autolysis of the hair cells, which may be one of the action mechanisms.

保护耳蜗毛细胞内溶酶体的完整性，防止毛细胞的自溶性损伤可能是当归的作用机制之一。

When PHB content was 85%-90%, membrane permeability would be increased by the abundantly accumulated in-cell PHB granules, and then the autolysis of recombinant cells occurred.

当细胞内PHB含量为85%~90%时，大量积累的PHB颗粒可以改变细胞膜的通透性，实现重组细胞的内控自裂解。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
