目的：探讨生理因素对受照的部分或完全乏氧的肿瘤细胞ＤＮＡ链断裂和ＤＮＡ－蛋白质交联（ＤＰＣｓ）的诱导和修复的影响。方法：分别选取处于指数生长期（ｐＨ６．６～６．７和７．２～７．３，３天）和坪期（ｐＨ６．８～６．９，葡萄糖几乎耗尽，５天）的９Ｌ大鼠脑肿瘤细
Objective: To investigate the effects of physiological factors on DNA strand breaks and DNA-protein cross-linking (DPCs) induction and repair of irradiated partially or completely hypoxic tumor cells. METHODS: 9L in the exponential growth phase (pH 6.6-6.7 and 7.2-7.3, 3 days) and ping phase (pH 6.8-6.9, glucose almost exhausted, 5 days) were selected. Rat brain tumor fine
