Introduction Actually, radiation alone is not enough to kill tumor cells efficiently because of the radioresistance of tumor cells. 关键词：放射增敏剂,天然产物,肿瘤,癌症,放射疗法|全部关键词
Glioma is the most common neoplasm in brain, which is commonly considered as the tumor tissues with high radioresistance. 胶质瘤是最常见的脑肿瘤,也是辐射抗性较强的肿瘤组织。
Backgroud and purpose: There is overwhelming evidence that hypoxia present in solid human tumors is a major factor contributing to radioresistance. 背景和目的：大量证据表明人类实体肿瘤中存在的乏氧细胞是影响放射治疗疗效的重要原因。
The pharmacological experiment indicates that the tea polyphenols micro-pill of the invention has good effect on radioresistance, anti-aging, etc. 药理实验表明，本发明微丸具有很好的抗辐射、抗衰老等作用。
These special natural products display broad biological activities,such as antioxidant,radioresistance,antimicrobials,antiviral,anticancer,plant growth inhibitory effects and antifeedant. 这些次生代谢产物具有多样的生物活性,包括抗氧化、抗辐射、抗菌、抗病毒、抗肿瘤、植物生长抑制和昆虫拒食等活性。
