Abstract
Trauma-induced primary damage is followed by secondary damage, exacerbating traumatic brain injury
(TBI). Dexpanthenol has been shown to protect tissues against oxidative damage in various inflammation
models. This study aimed to investigate possible antioxidant and neuroprotective effects of dexpanthenol
in TBI.
Wistar albino male rats were randomly assigned to control (n = 16), trauma (n = 16) and dexpanthenol (500 mg/kg; n = 14) groups. TBI was induced under anesthesia by dropping a 300 g weight from
70-cm height onto the skulls of the rats. Twenty-four hours after the trauma, the rats were decapitated
and myeloperoxidase (MPO) levels, luminol- and lucigenin-enhanced chemiluminescence (CL), malondialdehyde (MDA) levels, superoxide dismutase (SOD) levels, and catalase (CAT) and caspase-3 activities
were measured in brain tissues. Following transcardiac paraformaldehyde perfusion, histopathological
damage was graded on hematoxylin-eosin-stained brain tissues.
In the trauma group, MPO level, caspase-3 activity and luminol-lucigenin CL levels were elevated
(p < 0.05–0.001) when compared to controls; meanwhile in the dexpanthenol group these increases were
not seen (p < 0.05–0.001) and MDA levels were decreased (p < 0.05). Decreased SOD and CAT activities
(p < 0.01) in the vehicle-treated TBI group were increased above control levels in the dexpanthenol group
(p < 0.05–0.001). in the dexpanthenol group there was relatively less neuronal damage observed microscopically in the cortices after TBI.
Dexpanthenol reduced oxidative damage, suppressed apoptosis by stimulating antioxidant systems
and alleviated brain damage caused by TBI. Further experimental and clinical investigations are needed
to confirm that dexpanthenol can be administered in the early stages of TBI.
