Abstract: | Objective:To observe the effect of Pingxian granule on pathological structure of blood brain barrier and expressions of related proteins Cx43 and ICAM-1 in young epileptic modelled rat kindled with pentylenetetrazole.Methods:60 blank rats were selected as blank group.After successful preparation of epileptic model,180 young rats were randomly divided into model group,sodium valproate group(0.02 g/mL)and Pingxian granule group(0.19 g/mL);60 rats in each group were given intragastric administration for 21 days once a day.The blank group was given the same amount of normal saline.Brain tissues of rats were taken at 24 h,48 h,72 h,7 d,14 d and 21 d after gavage.The ultrastructure of blood-brain barrier was observed.The permeability of blood-brain barrier was determined.The expressions of Cx43 and ICAM-1 proteins were observed.Results:Pingxian granule could restore the ultrastructure of blood-brain barrier in young epileptic modelled rats,reduce the permeability of blood-brain barrier,and down-regulate the expressions of related proteins Cx43 and ICAM-1 of blood-brain barrier.Conclusion:Pingxian granule may play an anti-epileptic role by regulating the structure and permeability of blood-brain barrier. |
