查询词典 embryo

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。

It is estimated that there are about 40,000 functional genes.In order to understand those genes related to human diseases and the novel functional genes, the genetic manipulated mice including transgenic mice and knockout mice have been generated to facilitate the purpose.This transgenic core has been collaborated with industrial and research institutes for years, and has built up competitive know-how for transgenic mice, embryo cryopreservation, and pathogen free rederivation.

小鼠长期以来即为研究人类疾病最佳动物模式，2001年美国赛洛因公司已将小鼠129的两个品系之基因序列解码完成提供付费使用，2003年小鼠B6的基因序列也被Mouse Genomic DNA Sequencing Consortium解码完成，预估约有4万个功能基因，随著基因操控技术的成熟，制造出各种带不同基因缺陷的模式动物供生物医学研究已非难事。

THE CORRELATION OF ANTITROPHOBLAST ANTIBODY, EMAB AND HCG-AB WITH IVF-ET PREGNANCY OUTCOMEYANG ZONG-ZHI, SONG DONG-PO, ZOU SHU-HUA, et al（Medical and Health Care Center For Women and Childen of Qingdao, Qingdao 266011, China）［ABSTRACT］ObjectiveTo assess the effect of antitrophoblast antibody, EmAb and HCG-Ab on in vitro fertilization and embryo transfer outcome.MethodsThis study included 140 infertility women of unexplained reasons, salpingemphraxis and/or male factor undergoing IVF-ET, of whom, 31 with repeated failure of implantation; 26 with biochemical loss of pregnancy; 18 with clinical pregnancy loss. Sixty-five with clinical pregnancy served as control group.
