We made an extracorporeal blood irradiation system on adult male Sprague-Dawley (SD) rats. We used three wave lengths of each irradiation instruments which main wave lengths are 365nm, 465nm, 515nm. Extracorporeal circulation (ECC) was derived to ECC with irradiation. This systemis consisted of a tubing line, a roller pump and light emitting diode (LED) irradiation device. Animals were divided into not-irradiated group and other groups according to their irradiated wavelengths. We took the blood tests at pre-circulation with irradiation and post-circulationwith irradiation. We compared Experimental data betweenpre-circulationwith irradiationand post-circulation with irradiation.
