Resumo

Study design: Experimental, controlled trial. Objectives: The purpose of this study was to evaluate plasma iron and transferrin levels in a limb movement animal model with spinal cord injury (SCI). Setting: Universidade Federal de Sao Paulo, Departamento de Psicobiologia. Methods: In all, 72 male Wistar rats aged 90 days were divided into four groups: (1) acute SCI (1 day, SCI1), (2) 3 days post-SCI (SCI3), (3) 7 days post-SCI (SCI7) and (4) 15 days post-SCI (SCI15). Each of these groups had corresponding control (CTRL) and SHAM groups. Plasma iron and transferrin levels of the different groups were analyzed using a one-way analysis of variance (ANOVA) followed by Tukey's test. Results: We found a significant reduction in iron plasma levels after SCI compared with the CTRL group: SCI1 (CTRL: 175 +/- 10.58 mu gdl +/-; SCI: 108.28 +/- 11.7 mu gdl(-1)), SCI3 (CTRL: 195.5 +/- 11.00 mu gdl(-1); SCI: 127.88 +/- 12.63 mu gdl(-1)), SCI7 (CTRL: 186 +/- 2.97 mu gdl(-1); SCI: 89.2 +/- 15.39 mu gdl(-1)) and SCI15 (CTRL: 163 +/- 5.48 mu gdl(-1); SCI: 124.44 +/- 10.30 mu gdl(-1)) (P < 0.05; ANOVA). The SHAM1 group demonstrated a reduction in iron plasma after acute SCI (CTRL: 175 +/- 10.58 mu gdl(-1); SHAM: 114.60 +/- 7.81 mu gdl(-1)) (P < 0.05; ANOVA). Conclusion: Reduced iron metabolism after SCI may be one of the mechanisms involved in the pathogenesis of sleep-related movement disorders.
