| Outline of Final Research Achievements |
To investigate whether ETS-GS, a novel antioxidant that is a conjugate compound of glutathione, taurine, and vitamin E can treat disabilities caused by spinal cord injury and to determine the mechanism using rat models. After introducing a contusion injury at Th11 level into rats, they were separated into 3-day ETS-GS and saline dose groups. After day 3, the spinal cords were extracted for biochemical and histological analysis. A significant improvement in the Basso, Beattie, and Bresnahan (BBB) score was confirmed following ETS-GS dose. In addition, an ETS-GS-mediated reduction in myeloperoxidase (MPO), malondialdehyde (MDA), caspase-3 was observed along with a decrease in apoptotic cells as assessed by TUNEL staining. In conclusion, we observed that ETS-GS can treat disabilities caused by spinal cord injury, through suppressing inflammation, lipid peroxidation and inhibiting nerve cell apoptosis.
