Nature produces trace amounts of ozone in the air through lightning to purify the ecological environment. The product of ozone decomposition is oxygen, without secondary pollution. Ozone sterilizer is widely used in the epidemic prevention and control of intensive breeding farms and achieved remarkable results. If the concentration and action time of ozone can be accurately controlled, then ozone can quickly eliminate pathogens, without harming the normal cells in the human body. How to use medical ozone for epidemic prevention, treatment and health care is a subject worthy of serious study, which should arouse the attention of the experts in the field.展开更多

All subjects received semen analysis and related physical examination before the operation,and semen analysis and complication examination in the 3th, 6th and 12th months alter operation. Neither of groups had complication and notable uncomfortable symptoms following operation. The sperm disaPPearance rate in MPU group was 92.31%(12/13) while in MSR group, only one patient's sperm disaPPeared 3 moths after operation.During the other postoperative follow up periods all operated patients had spermatozoa allhough the sperm density decreased obviously and indicated partial vas occlusion.These results indicate that the MPU vas occlusion has a good sterilization elject,but the MSR has not.展开更多
