新的研究表明,对白细胞缺乏的病人具有一定作用的一种细胞刺激生长因子能使小鼠失明和死亡。新的研究与早期临床试验之间在方法学上有明显差别,因此,很难作出两种研究的比较。但研究人员告诫说,生长因子的过度刺激可能导致严重疾病的发生,这在目前的临 New research shows that a cell that stimulates growth in patients with a deficiency in leukocytes can cause blindness and death in mice. There is a significant difference in methodology between new research and early clinical trials, so it is difficult to compare the two studies. But researchers cautioned that overstimulation of growth factors could lead to serious disease, which is currently
