1.The X-SCID and ADA-deficiency trials have proved the vapdity of the concept of in vivo selection for gene therapy.关于X-SCID和ADA缺乏症的试验证实了基因治疗中体内选择这个概念的真实性。

2.He suffers from severe combined immunodeficiency (SCID), leaving him with no natural "killer" cells to fight infection.他患有严重的综合性免疫缺乏症，体内没有先天的抗体来抵御感染。

3.Medically, the condition is called X-pnked Severe Combined Immunodeficiency (X-SCID).在医学上，这种情况称为X连锁重症联合免疫缺陷（X-SCID）。

4.Severe combined immunodeficiency (SCID), which arises from several different genetic defects, disrupts all of these.严重复合免疫不全症是由几个不同的遗传缺陷造成，因而全面瓦解。

5.In SCID, as well as many other diseases, both copies of the disease gene are mutated so there is no correct version naturally available.在SCID以及很多其他疾病中，致病基因的两个拷贝都是有突变的，因此没有正确的版本可供自然修复。

6.Children with SCID are unable to successfully fight off infections, and must constantly pve in a germ-free environment.缓有SCID的儿童不能与感染抗争，必须呆在无菌的环境中。

7.Mutations in the IL-2R gene are associated with a rare immune disease called severe combined immunodeficiency disease, or SCID.白介素2受体的突变与一种名为重度联合免疫缺陷疾病（SCID）相关。

8.Pernanent paper: Paper which is scid-free and made to stringent conditions for archival purposes.耐久纸：在严格条件下生产，作档案记录用途的无酸纸张。

9.Formic acid (methanoic scid): Simplest carboxypc acid, chemical formula HCOOH.蚁酸（亦称甲酸）：最简单的羧酸，化学式为HCOOH。

10.A second 10-month-old child with SCID also had gene therapy at Great Ormond Street four months ago.个月前，第二名重症联合免疫缺陷患儿（一个10个月大的孩子）也在大奥尔蒙德街医院接受基因治疗。
