下列有关免疫抑制剂的叙述,何者正确?
(A)最常使用的组合是 cyclosporine + FK506 + prednisolone
(B)Cyclosporine 与 FK506 分子结构相似,但作用机制迥异
(C)原则上,免疫抑制剂需终生服用
(D)Antilymphocyte globulin(ALG)移植後需终生使用以避免排斥
答案: D
建议答案: 送分
申覆理由:
Antilymphocyte globulin (ALG) and traditional monoclonal antibody therapy
appear to act by relatively nonselective lymphocyte depletion or
inactivation.The profound immunosuppression resulting from the use of ALG or
OKT3 increases the recipient's risk for opportunistic infection or lymphoma.
Because of these risks, the use of ALG or OKT3 is generally limited to less
than 3 weeks.
因此Antilymphocyte globulin并非终生使用, 使用时间最好在三个礼拜内, 所以此题没有
选项正确, 故建议送分
