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