MATERIAL and METHODS: For 5 days after SCI rats were received saline in group C and Omegaven in group O. Locomotor strengths (BBB scale)of animals were rated at Day 0,7,14,21,28, and 35. At Day 35 spinal cord sampling was evaluated immunohistochemically.

RESULTS: BBB scores were 0 in early period after SCI was inflicted in both groups. BBB scores were progressively increased after Day 7 in both groups (p<.005). BBB scores were significantly higher in group O when compared with control group after Day7 in all times (p<.005). Neuronal injury (p<.002) and edema was much more in control group when compared with in group O (p<.005). Scores for white mater cavitation, demyelinization and vessel in growth were similar in both groups. VEGF expression in control group was higher (p=.019).

CONCLUSION: At the early period of SCI fish-oil emulsion treatment in rats, its anti-inflammatory effects leaded to decrease in edema and had positive effect at the prevention of neuronal injury. We believe that nutritional support with fish-oil emulsion in patients with SCI will result in patient's better clinical outcome and increase in quality of the patient's life.
