Cannabidiol is a natural herbal medicine known to protect the brain from traumatic brain injury (TBI). Here, a TBI rat model was established, with cannabidiol administered intraperitoneally at doses of 5, 10, or 20 mg/kg, 30 min before surgery and 6 h after surgery until sacrifice. Brain water content, body weight, and modified neurological severity scores were determined, and enzyme-linked immunosorbent assay, immunofluorescence staining, hematoxylin and eosin staining, Nissl staining, Evans-blue dye extravasation, and western blotting were performed. Results showed that cannabidiol decreased the number of aquaporin-4-positive and glial fibrillary acidic protein-positive cells. Cannabidiol also significantly reduced the protein levels of proinflammatory cytokines (TNF-α and IL-1β) and significantly increased the expression of tight junction proteins (claudin-5 and occludin). Moreover, cannabidiol administration significantly mitigated water content in the brain after TBI and blood-brain barrier disruption and ameliorated the neurological deficit score after TBI. Cannabidiol administration improved the integrity and permeability of the blood-brain barrier and reduced edema in the brain after TBI.
