Abstract
OBJECTIVE: The aim of this experimental study was to assess the effect of erythropoietin on a rat model, particularly under a renal ischemia reperfusion protocol. The beneficial or lack of effects of that molecule on the excreted renal product of serum uric acid were studied biochemically. MATERIAL AND METHODS: Forty rats were used with a mean weight of 247.7 gr. Serum uric acid levels were measured measured at 60 min after reperfusion (Groups A and C) and at 120 min after reperfusion (groups B and D). RESULTS: 1) Erythropoietin administration non-significantly decreased the serum uric acid levels non-significantly by 0.02 mg/dL [-0.2415423 mg/dL-0.2015423 mg/dL] (p=0.8560), in accordance with the paired t-test (p=0.8438). Reperfusion time non-significantly increased the serum uric acid levels non-significantly by 0.17 mg/dL [-0.0444933 mg/dL-0.3844933 mg/dL] (p=0.1169), in accordance with the paired t-test (p=0.1648). 3) The interaction of erythropoietin administration and reperfusion time non-significantly increased the serum uric acid levels non-significantly by 0.1 mg/dL [-0.0295564 mg/dL-0.2295564 mg/dL] (p=0.1264). CONCLUSION: Erythropoietin administration, reperfusion time and their interaction have no significant short-term alterations on serum uric acid levels. Conclusions cannot be extracted by non-significant p-values within 2 hours. Obviously, longer study times may permit safer results.
