Abstract:
OBJECTIVE:To study the antioxidant effects of Scutellaria baicalensis(SBE)on the model mice with Alzheimer’s disease. METHODS:All mice were treated by D-gal (150 mg/kg) and NaNO2 (100 mg/kg) for 60 d to reproduce the AD model mice,ip,once a day. Totally 60 mice were randomly divided into normal control group(isovolumetric sodium chloride injection), model group (isovolumetric sodium chloride injection),estradiol (0.4 mg/kg) group,and SBE high,medium and low doses (500,250 and 125 mg/kg). The mice were intragastrically administrated while modeling except normal control group,once a day, for continuous 60 d. The superoxide dismutase(SOD),catalase(CAT)activities and malondialdehyde(MDA)content in brain tis-sue ,and glutathione peroxidase (GSH-Px) activity in serum of mice were determined. RESULTS:Compared with normal control group,the SOD,CAT activities in brain tissue,and GSH-Px activity in serum of mice in model group were decreased,MDA con-tent in brain tissue were increased,with significant difference(P<0.01 or P<0.05);compared with model group,the SOD,CAT activities in brain tissue and GSH-Px activity in serum of mice in SBE high and medium dose groups were increased,MDA content was decrease,with significant difference (P<0.01 or P<0.05). CONCLUSIONS:SBE can enhance the antioxidant capacity in AD model mice by a mechanism that may be related to the improvement of related oxidation indicators’levels.
