Abstract

Acute renal injury induced by ischemia is a major cause of high morbidity and mortality in hospitalized patients and a common complication in hospitalized patients. Thus, the work with acute renal failure and renal ischemia has been studied for many years. Although serum creatinine concentration that is widely used as an index of renal function performs fairly well for estimating kidney function in patients with stable chronic kidney disease, it performs poorly in the setting of acute disease. Thus, an ideal biomarker for acute kidney injury would help clinicians and scientists diagnose the most common form of acute kidney injury in hospitalized patients, acute tubular necrosis, early and accurately, and may aid to risk-stratify patients with acute kidney injury by predicting the need for renal replacement therapy, the duration of acute kidney injury, the length of stay and mortality. In this study, renal ischemia and reperfusion were performed by clapming and un-clamping right renal artery in miniature pigs. Plasma blood urea nitrogen (BUN) and creatinine were examined at pre- clamping, after-clamping at 0, 1 and 3 hours. And we searched initial indicators in these samples. Also, renal tissue was collected and searched the initial indicator by PCR and western blotting. As a result, hypoxia inducible factor $1{\alpha}$ ($HIF1{\alpha}$), nuclear factor kappa-B ($NF{\kappa}B$), $I{\kappa}B$, erythropoietin (EPO), erythropoietin receptor (EPOR), angiopoietin-1 and vascular endothelial growth factor (VEGF) were showed significant changes among the renal protein. $HIF1{\alpha}$, EPO, and EPOR were showed significant changes among the renal gene. Thus, these markers will be used as initial diagnosis of acute renal failure.
