Radioautography indicated that there was a radioactive bright point, the binding rate of 125I labeled AMH with tumor cells reached 100％.

放射性自显影的研究显示，在卵巢GCT细胞膜处有放射性亮点，125I标记的AMH与卵巢GCT细胞结合率达100%。

Radioautography indicated that there was a radioactive bright point, the binding rate of 125I labeled AMH with tumor cells reached 100％. Conclusions AMH can be served as a specific tumor marker in the diagnosis of difficult and complicated tumors of ovary, and in the diagnosis,treatment and follow-up survey of the early GCT.

A human promyelocytic leukemia cell mutant (HL-60-AR) with deficiency in HGPRT and resistance to 8-AG was established by treat〓nt of the HL-60 cells with MNNG and prescreened in 0.3% agar RPMI-1640 semisolid medium containing 8-AG. The mutant cells show the following characteristics:(1) resistant to cytotoxic action of 8-AG and growing vigorously in medium containing 20ug/ml 8-AG;(2) capable of forming 〓〓 colonies in soft agar medium in the presenee of 8-AG:(3) highly sensitive to HAT selective medium and fail to growing in HAT medium of form colonies in soft agar medium containing HAT;(4) completely deficinet in HGPRT activity; and (5) no radioactive silver grains over the mutant cells due to the absence of -hypoxanthine incorporation showed by radioautography.

一、用MNNG诱变和8-AG进行抗性筛选，成功地建立了一株抗高浓度8-AG和完全缺失HGPRT活性的人早幼粒白血病细胞突变株(HL-60-AR)，该细胞能抵抗8-AG的毒性作用，对HAT选择培养基十分敏感，检测不到HGHRT活性，不能参入〓H一次黄嘌呤。
