| 摘 要： | 癌旁粘膜无论在形态和组织化学上都常与正常粘膜有差异。曾有人认为癌旁粘膜处于癌前病变状态。我们用聚合酶链式反应－－限制性片段长度多态性（ＰＣＲ－ＲＦＬＰ）分析方法检测了１３例结直肠癌及其相邻粘膜中ｋｉ－ｒａｓ基因的空变情况。结果发现癌组织和癌旁粘膜都有ｋｉ－ｒａｓ突变２例，仅癌组织有突变的２例，仅癌旁粘膜有突变有１例。该结果说明部分癌旁粘膜已经发生了ｋｉ－ｒａｓ基因的突变，并进一步证实ｋｉ－ｒａｓ

| Abstract: | The reduction of diesel emitted particulate components was investigated using a new-typerare-earth perovskite catalyst. Meanwhile, the morphological variation of diesel exhaust particulates across the catalyst was analyzed with transmitting electronic microscopy (TEM) and the exhaust resistance change caused by carbon deposit was tested. The result showed that this catalysthad a significant effect on reduction of SOF mass, Benzo (a) pyrene (BaP) and on morphology ofdiesel exhaust particulates. The increase of exhaust resistance by carbon deposit didn't deterioratediesel propertes and the regeneration of the catalyst could be achieved through altering operatingcondition. |
