Abstract
Background and Objective: Multiple sclerosis (MS) is a common neurological disease that increases oxidative stress and causes immune system disorders. Curcumin is the active component of turmeric with anti-inflammatory properties. This study was conducted to determine the effects of curcumin on cortisol, catalase, and nerve growth factor (NGF) expression in an animal model of MS.
Methods: This experimental study was conducted on 30 female Wistar rats. Experimental autoimmune encephalomyelitis (EAE) was chosen as an experimental model of MS. The rats were divided into 3 groups of 10, including a healthy control group, an affected group, and a group treated with curcumin. The disease was induced by immunization of rats with homogenized guinea pig spinal cord and Freund's complete adjuvant. Then, the immunized animals were allocated into two equal groups. Treatment with curcumin (100 mg/kg daily) was started 12 days after the immunization when the rats showed the first symptoms of neurologic disability. The treatment was continued until day 24 post-immunization. Simultaneously, the EAE group received the medicine solvent (distilled water). Finally, the rats' weights as well as cortisol, catalase, and NGF levels were measured in the study groups.
Results: Curcumin significantly increased the level of cortisol to a level equal to that of healthy rats (P<0.05). It also significantly increased the expression of NGF and reduced the amount of catalase in the affected rats (P<0.05). The curcumin administration significantly increased the overall weight of rats with MS but had no significant effect on the spleen weight of the treated rats.
Conclusion: Curcumin can be beneficial for treating EAE by reducing the destructive effects of oxidative damage and increasing NGF.

Abstract
Background and Objective: Individuals with a history of anterior cruciate ligament (ACL) injury are at a higher risk of re-injury compared to healthy individuals. ACL-injured patients exhibit weaker longitudinal arches and increased foot pronation compared to healthy individuals. This study aimed to determine the effect of short-term use of anti-pronation insoles on plantar pressure variables following ACL reconstruction (ACLR) with a pronated foot during gait.
Methods: This quasi-experimental study was conducted on 15 male participants who had undergone ACLR with a pronated foot (mean age= 23.2±4.5 years) and 15 healthy males (mean age= 22.7±4.3 years) in Ardabil, Iran during 2022. Plantar pressure values during gait with and without the use of anti-pronation insoles were recorded and compared using a foot scanner (sampling rate: 300 Hz).
Results: The effect of the group factor on the big toe plantar pressure variable was statistically significant (P<0.05). Pairwise comparison results demonstrated a significant increase in pressure in the ACLR group (154.63±41.71 N/cm²) compared to the healthy group (126.54±26.57 N/cm²) (P<0.05). Intragroup comparison results revealed a significant decrease in pressure on the second to fifth toes (215.73±60.74 N/cm²) and the first plantar (420.58±107.56 N/cm²) when using anti-pronation insoles compared to the non-insole condition (the second to fifth toes (201.57±76.21 N/cm²) and the first plantar (400.78±118.20 N/cm²) in the ACL reconstruction group (P<0.05).
Conclusion: The use of anti-pronation insoles can effectively reduce plantar pressure after ACLR in individuals with a pronated foot during gait.
