This study investigates the role of caspase-3 activation in neuronal death following traumatic brain injury.
Examined caspase-3 activation and its effects in injured rat brains compared to controls.
Administered caspase-3 inhibitor after brain trauma and assessed DNA fragmentation and contusion size.
Evaluated brain tissue loss at 3 weeks and functional outcomes after administering the inhibitor.
Caspase-3 activation increased in injured brain tissue versus controls, with elevated enzyme activity and substrate cleavage.
Caspase-3 inhibition resulted in reduced DNA fragmentation and smaller contusion size (p<0.05).
Functional outcome showed no significant improvement compared to the vehicle group.
