| Research Abstract |
Cancer cells in hypoxic conditions are known familiarly as X-ray resistant. When cancer cells were exposed to hydrogen peroxide just before the X-irradiation, the cells in hypoxic condition occurred death more than cancer cells in normoxic conditions. When hydrogen peroxide was administered into cell medium, oxygen generated. In our study, however, the oxygen pressure increased in the medium was a mere 3. 6 mmHg, which was not enough for hypoxic conditions to become normoxic conditions. It is considered that subcellular organella such as lysosome are concerned with this cell death.
