S. Subramanian et al., Attenuation of renal ischemia-reperfusion injury with selectin inhibition in a rabbit model, AM J SURG, 178(6), 1999, pp. 573-575
BACKGROUND: The selectin glycoproteins are involved in the pathogenesis of
renal ischemiare-perfusion injury, We investigated the ability of glycyrrhi
zin, a known selectin inhibitor, to attenuate renal ischemia-reperfusion in
jury.
METHODS: Eighteen New Zealand white rabbits underwent midline laparotomy wi
th renal artery cross-clamping, After 30 minutes of reperfusion, group 1 (c
ontrol, n = 10) animals received a saline infusion, while group 2 (GLY, n =
8) animals received a glycyrrhizin infusion. Renal function was compared b
etween the two groups after 72 hours of reperfusion. A t test was utilized,
with alpha set at P <0.05.
RESULTS: Group 1 and group 2 animals had similar baseline renal function. H
owever, after 72 hours of reperfusion, group 1 animals had a significantly
higher mean blood urea nitrogen creatinine ratio than group 2 animals (P <0
.01), indicating preserved renal function in rabbits treated with glycyrrhi
zin.
CONCLUSIONS: Selectin blockade using glycyrrhizin attenuates renal ischemia
-reperfusion injury when given 30 minutes after the onset of reperfusion in
a rabbit model, Am J Surg. 1999;178: 573-576. (C) 1999 by Excerpta Medica,
