Abstract | BACKGROUND: MATERIAL AND METHODS: Rat livers were harvested from male Wistar rats weighing 250-300 g. Three experimental groups (n=5 per group) were studied: (1) CONTROLS: cold static storage in HTK for 24 h, (2) DCD: 30-min warm ischemia time and 24-h cold static storage in HTK, and (3) DCD+Hydroxyectoine: like DCD, but with 24-h cold static storage in HTK+Hydroxyectoine. Viability of the livers was assessed after 24 h of preservation by isolated perfusion for 45 min with oxygenated Krebs-Henseleit buffer solution. RESULTS: (mean ±SEM, Control vs. DCD vs. DCD+Hydroxyectoine) Parenchymal enzyme release was significantly lower in DCD+Hydroxyectoine compared to DCD (AST: 9±0.54; 56.8±2.05; 32.2±7.25 U/L, ALT: 9.5±0.5; 37.75±9.6; 17.5±4.17 U/L). Bile production at the end of 45 min reperfusion was significantly higher in DCD+Hydroxyectoine (5.16±1.32; 1.36±0.34; 10.75±2.24 µL/g liver weight/45 min). Malondialdehyde values were significantly lower in DCD+Hydroxyectoine (0.8±0.09, 1.14±0.18, 0.77±0.08 nmol/mL). Intercellular adhesion molecule-1 showed significantly lower values in DCD+Hydroxyectoine (219.07±51.79, 431.9±35.70, 205.2±37.71 pg/mL) and the portal venous pressure at 45 min was lower compared to DCD (20.41±0.12, 27.47±0.45, 22.08±0.78 mmHg).
