| Research Abstract |
Disinfection of cardiovascular tissues, like cardiac valve or vessels, by using radiation of gamma radiation was tried. Gamma radiation of 2kGy or 4kGy was applied to MRSA suspensions, resulting in no MRSA was detected. Then X-ray was used because X-ray is easier than gamma radiation in the usual hospitals. MRSA could be reduced with 100Gy of X-ray, and MRSA could be reduced in 16% by 400Gy of X-radiation. At 400Gy X-radiation, growth of cultured smooth muscle cells was not deteriorated.
