The ongoing works of our laboratory on subjects of intestinal injuries induced by heavy ions and protection against these injuries are also presented.
结果表明，具有高let的重离子辐射与低let辐射相比，能够更有效的诱发DNA分子发生双链断裂，并使双链断裂的分布更局部和更密集。
Results show that high-LET heavy ion radiation more effectively induces DNA DSBs in comparison with low-LET radiation, and produces DSBs that are distributed more locally and more densely.
