Both c-myc and c-fes were detectable in leukemic cells as well as in immature granulocytes and erythroblasts of normal bone marrow, but the expression extent varied in different cases. The levels of c-myc expression in leukemic cells were higher than those in controls (P<0.001). There was no difference of c-fes expression in two groups of bone marrow cells (P>0.05). This technique provides us a new method in studying variations of proto-oncogene expression in leukemic cells.展开更多

The experimental method was found difficult to do this. We will apply the Boundary Element Method(BEM) to the problem and explain the results obtained. The numerical method seems to be a powerful tool in this situation.展开更多
