ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of glycine on CD14 and NF-kappa B in Kupffer cells from rat liver grafts after ischemia-reperfusion injury (IRI).</p><p><b>METHODS</b>The rats were randomly divided into an IRI group, saline solution preconditioning group, and glycine preconditioning group. Their survival rates, graft functions, and hepatic histopathologic examinations were observed after IRI. Kupffer cells (KCs) following IRI were isolated and cultured to detect CD14 mRNA, NF-kappa B binding activity, and the TNF alpha and IL-1 level in the supernatant of the media.</p><p><b>RESULTS</b>(1) Glycine preconditioning greatly enhanced the one-week survival rate (chi2 = 6.67 and 8.57 respectively), improved graft function, and ameliorated the histopathologic signs of injury. (2) The CD14 mRNA expression level (F = 7.64), NF-kappa B binding activity (F = 11.47), TNF alpha and IL-1 production (F = 14.08 and 9.56 respectively) in the glycine group were significantly lower than those in the other two groups.</p><p><b>CONCLUSION</b>Glycine could efficiently protect rat liver grafts from ischemia-reperfusion injury by repressing the expression of CD14 and NF-kappa B binding activity in Kupffer cells and inhibiting the productions of TNF alpha and IL-1.</p>
