The effect of acridine orange photodynamic antimicrobial chemotherapy for drug resistant bacterias was examined.Growth was significantly suppressed at 50 microgram/ml of acridine orange solution in Acinetobacter, vancomycin-resistant enterococci, enterococci, methicillin-resistant Staphylococcus aureus, Staphylococcus aureus, the growth rate was 4%, 17%, 18%, 7%, and 15% respectively.It was not revealed mechanism of growth inhibition of bacteria by the present method. Since the relatively strong growth inhibitory effect was observed against methicillin-resistant Staphylococcus aureus ,I was considered that acridine orange photodynamic antimicrobial chemotherapy was also possible clinical application in infection of bone and soft tissue.

研究吖啶橙子光动力抗菌化疗对耐药菌的作用，50 μ g/ml的吖啶橙子溶液对不动杆菌、万古霉素耐药肠球菌、肠球菌、甲氧西林耐药金黄色葡萄球菌、金黄色葡萄球菌的生长有明显抑制作用，生长率分别为4%、17%、18%、7%，本方法不能揭示细菌生长抑制的机理。由于吖啶橙子光动力抗菌化疗对耐甲氧西林金黄色葡萄球菌有较强的生长抑制作用，因此我认为吖啶橙光动力抗菌化疗在骨和软组织感染中也有可能临床应用。
