  • Inhibition of Flavonoids from Scutellaria baicalensis Stems and Leaves against Abnormal Formation of PHF and Regulation of PP in OA Induced Brain Injury in Rats

    Jianjun CHENG;Hong MIAO;Shuai MA;Yang GAO;Yazhen SHANG;

    [Objectives] To explore the inhibitory effects of flavonoids from Scutellaria baicalensis Georgi stems and leaves against abnormal formation of PHF and regulation mechanism of protein phosphatase(PP) in okadaic acid(OA) induced brain injury in rats.[Methods]Male Sprague-Dawley rats were treated with OA(200 ng/kg) in the lateral ventricle to establish a memory impairment model,and Morris water maze was used to screen the memory impairment model.Rats were intragastrically administered with 25,50 and 100 mg/kg SSF daily for 36 d.The protein expressions of PHF,PP1,PP2A-Cα,PP2A-Cβ,PP2 CA and PP2 CB in rat cortex and hippocampus were determined by Western blot.Ginkgo biloba leaf flavonoids were used as positive control drugs.[Results]Compared with the sham-operated rats,the expression of PHF protein in the cortex and hippocampus of the model group was significantly increased(P < 0.01);protein expression of PP2A-Cα and PP2A-Cβin the cortex and hippocampus,and PP2 CB in the hippocampus were significantly decreased(P < 0.05);protein expression of PP2 CA and PP2 CB in the cortex was significantly increased(P < 0.01);protein expression of PP1 in the cortex was significantly decreased(P < 0.01).Compared with the model rats,25,50 and 100 mg/kg SSF 36 d reversed the protein expression of PHF,PP2A-Cα and PP2ACβ in rat cortex and hippocampus and expression of PP1 in rat cortex induced by OA,but had no significant effect on the protein expression of PP2 CA and PP2 CB,G.biloba flavonoids also showed similar results to SSF.[Conclusions] SSF can significantly inhibit the abnormal formation of PHF in rat brain induced by OA.The inhibitory effect may be related to the regulation of PP1,PP2A-Cα and PP2A-Cβ protein expression in cerebral cortex and hippocampus by SSF,but less related to the regulation of PP2 CA and PP2 CB.

    [Objectives] To study the differences in the effects of Rheum officinale and wine prepared Rheum palmatum Dachengqi Decoction(DCQ) on laxative effect of mice.[Methods]First,72 mice were randomly divided into positive control group,blank control group,6 and10 g/kg dose R.officinale DCQ groups,6 and 10 g/kg dose wine prepared R.palmatum DCQ groups.After administration at the dose of20 m L/kg,metabolic cage method and carbon powder propulsion were used to conduct Na+-K+-ATPasc activity experiment,and the comparison was made for the differences in the normal laxative effect of R.officinale and wine prepared R.palmatum on DCQ,the carbon powder propulsion rate,and Na+-K+-ATPasc activit.[Results]There are differences in the laxative effect of R.officinale and wine prepared R.palmatum on DCQ,but their differences in changes are,to some extent,connected with R.officinale and wine prepared R.palmatum.From comparison of R.officinale DCQ group,wine prepared R.palmatum DCQ group,blank control group,and positive control group,it is found that there are differences in the normal laxative effect of normal mice,carbon powder propulsion,and inhibition of Na+-K+-ATPase activity.In addition,the comparison of drug administration groups indicates that the differences in the effects of R.officinale DCQ group are most significant,and there are significant differences in the 6 and 10 g/kg groups.[Conclusions]There are certain differences in the influence of R.officinale and wine prepared R.palmatum Dachengqi Decoction on normal laxative effect of mice,which may be connected with the fact that changes in main chemical components of king drugs R.officinale and wine prepared R.palmatum lead to changes in the dissolution amount of anthraquinones in the compound Dachengqi Decoction.
