ABSTRACT
Aim To study the neuroprotective effect of p-benzoyl salidroside (pOBz), a derivative of salidroside, on MCAO model rats.Methods ( 1 ) Thirty healthy adult male SD rats were randomly divided into Sham group, MCAO group and MCAO + pOBz group (25, 50, 1(X) mg • kg"1).MCAO model was made by suture-embolus method.The rats were scored for neurological function impairment and weighed every day.pOBz was intraperitoneally injected and administered continuously for two days after preparation of MCAO model.The cerebral infarction volume of rats was detected by MRI.( 2 ) Twenty-four healthy adult male SD rats were randomly divided into Sham group, MCAO group, MCAO + pOBz group (50 mg • kg"1 ) and MCAO + Sal group (50 mg • kg 1 ).The model was made by the suture-embolus method.pOBz was in-traperitoneally injected and administered continuously for one day.Western blot was used to detect the ex pression of NeuN, EGR1 , Bcl-2 and Bax.(3) Eighteen healthy adult male SD rats were randomly divided j j into Sham group, MCAO group and MCAO + pOBz group ( 50 mg • kg 1 ).Administration continued for 2 days.Immunofluorescence staining was used to detect the expression of NeuN.Results Intraperitoneal injection of pOBz for 2 days could reduce the cerebral infarction volume of MCAO rats, improve neurological impairment and increase the expression of NeuN and EGR1 , and the effect was better than that of Sal.pOBz improved Bcl-2/Bax in brain tissues of MCAO rats to the same extent as Sal did.Conclusions pOBz can reduce the volume of cerebral infarction in MCAO rats and has better neuroprotective effect than that of salidroside.
