Popis: | Restoration of blood flow to an acutely ischemic lower limb may, paradoxically, result in systemic complications and unexpected mortality. We investigated the effect of acute ischemia-perfusion of the lower limb on cytokine production and end organ function. Plasma concentrations of tumor necrosis factor-alpha (TNF-a) and interleukin-6 (IL-6) were determined in five groups of male Wistar rats: control, 3 hours of bilateral hind limb ischemia alone, and 3 hours of bilateral hind limb ischemia followed by 1 hour, 2 hours, or 3 hours of reperfusion, respectively. In a second experiment, the effect of lower limb ischemia-reperfusion on remote organs (lung, liver, and kidney) was assessed biochemically and histologically. There was a significant increase in plasma concentrations of TNF-a in plasma of animals subjected to 3 hours of bilateral hind limb ischemia followed by 1 hour of reperfusion, 40.1 +/- 4.4 pg/ml, when compared with controls, 22.6 +/- 4.4 pg/ml, or animals in the ischemia-alone group, 16.3 +/- 5.2 (p |
