恶性肿瘤的基因治疗是近年来倍受重视的研究课题之一。Ram等报道[1]，采用基因重组技术，将单纯疱疾病毒（herpessimplexvirus，HSV）的胸苷激酶（thyAndinekinase，TK）基因克隆至逆转录病毒表达载体，辅以环氧鸟苷（ganciclovir，GCV）治疗神经胶质瘤，收到良好效果．这种以T
Gene therapy of malignant tumors is one of the most important research topics in recent years. Ram et al. [1] reported that the gene of thyAndinekinase (TK) of herpes simplex virus (HSV) was cloned into a retroviral vector by gene recombination and supplemented with ganciclovir (GCV ) Treatment of glioma, received good results. This to T
