Sodium cromoglycate decreases sensorimotor impairment and hippocampal alterations induced by severe traumatic brain injury in rats.
Severe traumatic brain injury (TBI) results in significant functional disturbances in the hippocampus. Studies support that sodium cromoglycate (CG) induces neuroprotective effects. This study focused on investigating the effects of post-TBI subchronic administration of CG on hippocampal hyperexcitability and damage as well as on sensorimotor impairment in rats. ⋯ The TBI+CG group presented hippocampal volume reduction (12.7%, p = 0.94) and damage (0.10 ± 0.03 mm3, p > 0.99) similar to the TBI+SS group. However, their hippocampal neuronal preservation was similar to that of the Sham+SS group. These results indicate that CG represents an appropriate and novel pharmacological strategy to reduce the long-term sensorimotor impairment and hippocampal damage and hyperexcitability that result as consequences of severe TBI.
