The effects of hapten structure on antibodies properties and hapten heterology on ELISA sensitivity were also investigated. The results show that haptens with simple spacer-arm can generate antibodies with desired properties, and hapten heterology can improve ELISA sensitivity significantly.

建立检测硫代磷酸二乙酯类农药的间接竞争酶联免疫分析方法，分析探讨了免疫半抗原结构对抗体特性的影响，并阐述了包被半抗原结构对ELISA灵敏度的影响规律。

Detection of HLA-B27 and its related B antigens was useful to investigate the heterozygosis of these B loci and the cross-reactivity of their antigens.

检测HLA-B27及其相关B位点抗原的频度有助于分析这些位点的杂合及其抗原的交叉反应性的特点。

With the establishment of animal models of aortic homograft transplantation, using immunohistochemical staining, the difference of the expression of MHC Ⅰ antigen and MHC Ⅱ antigen was detected between fresh aortic homografts and cryopreserved ao rtic homografts.

建立大鼠同种异体主动脉移植模型，采用免疫组织化学实验研究新鲜主动脉和低温保存的主动脉同种异体移植后MHC Ⅰ类抗原和MHCⅡ类抗原表达的区别。

Objective To probe into a diagnosis value of CEA,CA50in serum and hydrothorax for the pa-tients with lung cancer.

目的 探讨血清和胸腔积液癌胚抗原、糖类抗原CA50（CA50）在肺癌患者诊断中的价值。

Although powerful immunosuppressant drugs such as CsA and FK506 can suppress rejection, their side effects such as hyperpiesia, hepatorenal toxicity, severe infection, malignant degeneration limit their long time usage. Nowadays the key method to avoid or alleviate these side effects is induction of immune tolerance or specific low immunoreaction state with simultaneous maintenance of immune response against other antigens (including anticancer, anti-infection and so on).

尽管CsA和FK506等强有力的免疫抑制剂己被应用，但由其所产生的肝肾毒性、严重感染和致肿瘤性等副作用仍然未能解决，因此造成宿主对移植抗原处于免疫耐受状态或低免疫反应状态，又不影响机体对其他抗原的正常免疫应答能力，是目前器官移植术后解决排斥反应的根本途径。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
