The influence of levosimendan and iloprost on renal ischemia-reperfusion: an experimental study.
    Interactive cardiovascular and thoracic surgery, 2008, Volume: 7, Issue:2

    The effects of iloprost on ischemia-reperfusion injury have been studied on the skeletal, muscle, liver, myocardium, kidney, and spinal cord. However, no sufficient data exist about effects of levosimendan on renal ischemia-reperfusion injury. The purpose of this experimental study was to investigate and compare effectiveness of levosimendan and iloprost on renal injury induced by ischemia and reperfusion. Fifty rabbits were divided into five groups. Levosimendan was continuously infused starting half an hour before the cross-clamp. Cross-clamp time was one hour. After one hour ischemia, levosimendan was continued for 4 h in Group A whereas Group B took iloprost in the same protocol. Group C was the control group which did not receive any medication. Group D was sham group and Group E was medicated both iloprost and levosimendan. Renal tissues were histologically and biochemically evaluated. The histological scores were obtained according to presence of tubular necrosis and atrophy, regenerative atypia, hydropic degeneration (Group A vs. Group C<0.001, Group B vs. Group C<0.001, Group D vs. Group C<0.01, Group E vs. Group C<0.001). Mean malondialdehyde levels were 114+/-12 nmol/g tissue; in Group A 121+/-13 nmol/g tissue, in Group B 134+/-13 nmol/g tissue, in Group E 130+/-11 nmol/g tissue, in Group D 134+/-11 nmol/g tissue (Group A vs. Group B; P=0.003, Group B vs. Group D; P=0.132, Group A vs. Group E; P=0.132). Malondialdehyde levels and histologic scores of all of the groups were significantly different from the control group. Iloprost and pentoxyfillin reduced renal ischemia-reperfusion injury in rabbit model. There was no significant difference between these two medications.

The effects of iloprost and vitamin C on kidney as a remote organ after ischemia/reperfusion of lower extremities.
    The Journal of surgical research, 2007, Jun-01, Volume: 140, Issue:1

    Abdominal aortic surgery can cause ischemic/reperfusion (I/R) injury in not only the lower extremities, but also in the remote organs and tissues such as lungs, kidneys, heart, and liver during abdominal aortic surgery. It can result in mortality and morbidity because of the remote organ injury in early postoperative period. In this study, we investigate the effects of iloprost and vitamin C on the kidney remote organ damage after I/R following abdominal aortic surgery.. Thirty-four adult male Wistar rats were used and divided into five groups. I/R was studied infrarenally in the abdominal aorta following a median laparotomy. The left kidney was excised immediately following the laparotomy in group I (n = 6, normal group). Group II (n = 6) was the sham group. Group III (n = 6, control group) was subjected to 3 h of ischemia followed by an hour of reperfusion. Group IV (n = 8) was given iloprost 20 ng/kg/min during I/R period before aortic-clamping. Group V (n = 8) was given vitamin C 100 mg/kg during I/R period before aortic-clamping. Arterial blood samples were obtained to determine the levels of blood pH, pO(2) (mmHg), pCO2 (mmHg), HCO(3) (mmol/L), and plasma malondialdehyde (MDA, nmol/mL) at the end of reperfusion period in all groups. The left kidneys were used for remote measurements of tissue MDA (nmol/g.w.t) and scored by histopathological examination for acute inflammation.. While the arterial blood pO(2) and HCO(3) levels significantly increased, the plasma and renal parenchymal MDA levels significantly decreased in both group IV and group V when compared to group III (P < 0.05). Histopathological and acute inflammation scores statistically decreased in both group IV and V compared with group III (P < 0.05). Although MDA levels, histopathologic and acute inflammation scores in group V were lower than group IV, the differences were not statistically significant (P > 0.05).. Both iloprost and vitamin C decreased remote organ damage on the kidney after I/R of lower extremities in the rat model. However, vitamin C is more effective than iloprost in preventing postoperative renal dysfunction.
