医用臭氧对大鼠骨骼肌病理学的影响英文摘要： Impact of Different Concertrations of Ozone Injection on Pathological Changes of Rat Skeleta Muscle 　 [Abstract]　Objective　 To evaluated the pathological changes of skeletalmuscle in normal rabbit by different concentrations of ozone injection. Methods　30 wistar rars were randomly divided into 5 groups (n=6). group Ⅰozone10， group Ⅱozone30， group Ⅲozone50， group Ⅳozone80， group Ⅵcontrol. In group Ⅰ， Ⅱ， Ⅲand Ⅳ，1ml of ozone 10μg/ml、30μg/ml、50μg/ml、80μg/ml was injected into right ectogluteus respectively，and in group Ⅴ，punctura at the same point without any injection. Biopsy was performed after 10min，30min and 3 weeks with the lightmicroscope，selecting the injection area. Results Compared to the control, light microscope of group Ⅱ, Ⅲ and Ⅳ showed myocyte swelling, myocyte′s bouncary became unclear, transverse striation became disorder, myocyte necrosis, dissolve and vacuolus degeneration partly after 10min both in two groups. Inflammation cells infiltrated in muscle interspace and blood vessel based on myocyte necrosis and dissolve in the injection area after 30min. Myocyte atrophy obviously, fibrous tissue accrementition ponderosus, hyalinization partly could be seen after 3 weeks. There were no abnormal pathological changes in group Ⅰand Ⅴ. Conclusions　 Myocyte damage occurs after injection of ozone with concentration of 30μg/ml、50μg/mland 80μg/ml， fibrous tissue repairs the damage after 3 weeks. Ozone with concentration of 10μg/mldo little harm to skeletal musle.
