Effect of Borneol on Sodium Valproate Passing Blood-brain Barrier / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo observe the effect of berneol on sodium valproate passing the blood-brain barrier in rabbits.Methods12 rabbits were randomly divided into the control group and borneol group with 6 animals in each group. All animals were treated with intravenous infusion of sodium valproate until steady state; while the rabbits of the borneol group received oral borneol. The sodium valproate concentration in serum and cerebrospinal fluid (CSF) was determined. The pharmacokinetics parameters obtained from two groups were analyzed. ResultsIn the berneol group, the mean drug concentration in CSF and area under curve increased significantly ( P<0.05) compared with those of the control group, and the time of drug reaching the peak concentration in CSF was 6 hours, the ratio of CSF to plasma also increased significantly ( P<0.05), while the blood concentration not increased.ConclusionBorneol can enhance the permeability of blood-brain barrier to sodium valproate, but has small influence on blood concentration.
