    Abstract:
    To study the protective effect of 1,6-diphosphate fructose (FDP) on acute ischemia damage in brain, heart and liver, we observed its effect on acute ischemic renal failure (AIRF). AIRF in male Wistar rats was produced by renal arterial clamping for 45 minutes and reperfusion for 90 minutes. The rats were divided into 4 groups according to their age and FDP therapy: G1: young (3-4 months) AIRF rats without FDP; G2: old (26-27 months) AIRF rats without FDP; G3: young AIRF rats with FDP (0.5g/kg) i.v. infusion; G4: old AIRF rats with FDP. Inulin clearance (CIn), PAH clearance (CPAH), urinary sodium (UNA) were examined before ischemia and 30, 60 and 90 minutes after reperfusion. After reperfusion for 90 minutes, renal cortex was taken for the examination of renal mitochondrial ATP synthetic content (miATPs). CIn and CPAH were lower in G2 than in G1 (0.24 +/- 0.12 vs. 1.75 +/- 0.79, P < 0.01; 0.87 +/- 0.42 vs 7.12 +/- 4.04, P < 0.05, at 90 minutes reperfusion). CIn and CPAH in G1 showed an auto-recovery up to 40.1% and 33.7% of the level in contrast to G2. In G3 and G4 original FDP infusion resulted in a significant increase in miATPs and CIn (609 +/- 145 vs 389 +/- 97; 569 +/- 77 vs 338 +/- 61, P < 0.02; 2.47 +/- 0.58 vs 1.75 +/- 0.79, 1.29 +/- 0.42 vs 0.24 +/- 0.12, P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
