A study on the antitumor efficiency of hematoporphyrin sonochemically activated by bi - frequency ultrasounds 复频超声声化学激活血卟啉抗肿瘤效率的研究
2.
The hematoporphyrin sensitizer used in photodynamic therapy produce toxic substance through translating energy to oxygen molecule , so the distribution of oxygen in tissue have special value as there has consumption of oxygen during photodynamic therapy 光动力疗法使用的叶琳类光敏剂主要是通过将能量转移到氧分子产生单线态氧来产生毒性物质，因此在光动力治疗中有氧的消耗，使组织中氧分布对光动力作用具有特殊意义。
