Abstract:
Introdution: According to importance of complimentary therapies. This study was conducted to investigate the effect of a four-week aerobic physical activities in water on the extent of clinical improvement and amount of Tumor Necrosis Factor alpha, TNF-α, Interleukin 10, IL-10 on serum levels and brain-derived neurotrophic factor in the brain tissue of the animal model of of multiple sclerosis (MS) via inducing experimental autoimmune encephalomyelitis (EAE).
Methods
In this experimental study, a total number of 80 female Syrian mice from the race of C57BL/6,, aging 10 to 12 weeks and weighing 20 ± 2 gram were divided into eight groups of 10, namely, control, swimming, MS, MS + swimming, MS + interferon beta (INF-β), MS + interferon beta + swimming, MS + solvent, and MS + solvent + swimming environment. For induction of EAE, 300 μg (35-55) myelin oligodendrocyte glycoprotein (MOG) was first mixed in 100 μl phosphate buffered saline (PBS) with complete Freund's adjuvant (CFA) and injected subcutaneously (SC). At the time of injection and after 48 hours, 300 ng pertussis toxin was diluted in PBS and injected intraperitoneally (IP). During a week after the treatment, mice receiving were the drug in form intraperitoneal received 150 IU/g of the drug per day. Clinical symptoms and the mice's weights were recorded every day. Physical activity group did the aerobic activities for four weeks, five sessions a week, 30 minutes each session. Finally Brains were extracted and blood samples were taken from the heart and enzyme-linked immunosorbent assay (ELISA) was applied to measure markers. Data analysis was done using one-way ANOVA.
Results
Based on the findings of this study, physical activity compared to interferon beta-1 treatment significantly increased the BDNF factor in mice, increased IL-10, and decreased TNF-α in serum .
Conclusion
Aerobic swimming exercises could most probably help remyelination by regulation of inflammatory factors and lowering the speed of myelin destruction, hence, helping the clinical improvement in patients with multiple sclerosis.
