以色列科学家即将使用由成长八天大的男婴身上切除下来的包皮来制造干扰素。干扰素仅在人体内有小量发现。因为干扰素只能在人体的细胞内生长,所以不大可能大规模使用。医治一个患癌症的病人,大约需一万五千美元,现在所生产的干扰素,大部份将留作研究用,而不作广泛的实际治疗 Israeli scientists are about to make interferons using the foreskin cut from an eight-day-old baby boy. Interferon is found only in small quantities in the human body. Because interferon can only grow in the body’s cells, it is unlikely to be used on a large scale. The cost of treating a patient suffering from cancer is about $ 15,000. Most of the interferons now produced will be reserved for research without extensive actual treatment
