    Abstract:
    The response of tumor necrosis factor alpha (TNF alpha), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), interleukin-1 receptor antagonist (IL-1ra), macrophage colony stimulating factor (MCSF), white blood cell (WBC), platelet (Plt), lactic acid (LAC) to cardiopulmnary bypass (CPB) were studied until 48 hours after aortic declamping in 11 patients who underwent elective CABG (n = 4), mitral valve plasty or replacement with modified maze procedure (n = 5), and both procedures (n = 2). The highest levels of the cytokines IL-6, IL-8, IL-10, and IL-1ra were observed after the removal of the cross clamp. These cytokines just after the aortic declamping are likely to be occurred not only by an interaction of the blood components with the artificial surfaces, but also by ischemia-reperfusion injury upon discontinuation of the aortic clamping. MCSF increased gradually in the late post-CPB phase and reached a peak at 48 hr after aortic declamping. MCSF may play an important role in regulating hematopoiesis on the postoperative days 1 and 2 in patients. In conclusion, the therapy based on the kinetics of these cytokines would be useful for patients undergoing CPB.
