MAPK10 and brain injury: Salidroside (50 mg/kg·d, 100 mg/kg·d, and 200 mg/kg·d intragastrically administrated for 12 weeks) could dose-dependently inhibit neuronal apoptosis, decrease MDA content, increase SOD activity, and inhibit p-JNK3/JNK3 and caspase-3 protein expression in the hippocampus of rats after traumatic brain injury.
