电子顺磁共振对人肺腺癌细胞生长分裂的影响

电子顺磁共振对人肺腺癌细胞生长分裂的影响 A STUDY ON EFFECT OF TREATMENT OF ELECTRONIC PARAMAGNETIC RESONANCE （EPR） ON GROWTH AND PROLIFERATION OF HUMAN LUNG ADENOCARCINOMA CELL LINE 胡修愚 1 2 3 first-author 李文鑫 1 2 3 姜兰 1 2 3 曾灵芳 1 2 3 汤艳芬 1 2 3 武汉大学病毒系83级 武汉大学病毒系83级 湖北工学院 学生 湖北工学院 学生 讲师 讲师 用自制的电子顺磁共振（EPR）仪对人肺腺癌细胞进行了处理观察:发现在等时间和等功率的条件下,不同频率对人肺腺癌细胞的作用不同,表现为抑制或促进;在等时间和同一共振频率条件下,不同的功率对癌细胞的作用也不同。以人羊膜传代细胞为对照,观察了在同一条件下EPR对人正常传代细胞和对人肺腺癌细胞的作用。在人肺腺癌细胞抑制最强的点上,对人羊膜细胞的生长抑制却很弱,二者相差七倍左右。 In this paper, the effect of treatment of EPR on growth and prolifer- ation of human lung adenocacinoma cell line is studied. At the same duration of treatment and the same power the effect of EPR on cancer cells depend upon the frequency and the effect is either promoted or inhibited. The form of cancer cells is changed and they are diminished at the promoted point. At the inhibited point, their form does not change, but their quantity is increased. The relation between ralative ratio of inhibition （η） and frequency is not linear: η=58% at f=92 MHz; η=-55%（promoted point） at f=102MHz; η=53% at f=122Mtz. The effect of EPR on cancer cells depend upon the power. On the other hand, we compare the human amnion cells of calture with cancer cells. The cancer cells are inhibited intensely and the effect on human amnion ceils are very weak at the same condition. The ratio of inhibition for cancer cells are more about 7 times than other, i. e. the human amnion cells are insensible for the treatment of EPR. 电子顺磁共振 癌细胞 生长和分裂 1988-03-01 2021-04-01 3
