Methods Freshly isolated eosinophils were cultured in vitro for 24 hours with granulocyte-macrophage colony factor to induce HLA-DR expression, and then exposed to different concentrations of tetanus toxoid. The capacity of HLA-DR+ eosinophils to function as APC was evaluated with the response of T cell proliferation induced by eosinophils.

新分离的EOS经人重组粒细胞-巨噬细胞集落刺激因子刺激24小时，以诱导HLA-DR的表达，然后将其暴露于不同浓度的TT，检测HLA-DR+EOS对自身T 细胞增殖反应的影响，以评价EOS呈递抗原的能力。

维生素d是自然生产时，皮肤暴露于太阳的紫外线。

In the laboratory,unmated females were placed with randomly chosen males to determine whether,given the opportunity,females would be found mating with the largest available males. I exposed amplexing pairs to other males to determine if larger or smaller males would displace amplexing males.

在实验室内，令未交配雌体选择随机选出的雄体，观测雌体是否与最大的雄体交配；将抱对的蛙暴露于其它雄蛙，观测其它较大或较小的雄蛙是否取代已抱对的雄蛙。

C. Etiology. Exposure of the endometrium to continuous estrogen unopposed by progesterone can lead to endometrial hyperplasia.

2000B.The xanthophyll cycle plays a role in protection of PS II from photoinhibition in senescent leaves by dissipating excess excitation energy, in particular when the leaves are exposed to high light levels (Lu et al.2001a, b).

。叶黄素循环中发挥作用，在保护的PS二，从光合作用的衰老叶片逐渐消退过剩的激发能量，尤其是当叶片暴露于高光层次（卢等al.2001a ， b ）款。

DDS was used as test drug for determination of acetylator phenotype employing HPLC.The results showed that both the occupational and non-occupational exposed group were predominantly slow acetylators(52.2％and 45.5％),higher than that in the exposed controls(13.0％)(0 05).The risks for bladder cancer with the slow ace...

结果表明。无论有无2－萘胺职业接触史，膀胱癌病人中慢型乙酰化者所占比例（52.2％和45.5％）均高于对照组（13.0％），且差异有显著性（P＜0.05），比值比0R分别为5.56（95％可信限＝1.02～30.3）和7.25（95％可信限＝1.70～30.3），提示慢型乙酰化者若暴露于2－萘胺更易患膀胱肿瘤，乙酰化慢表型是膀胱癌的一个遗传易感因素。
