Abstract:
Aim To detect the effect of a combination of extracts of ginseng and ginkgo biloba(Naoweikang,NWK) on acetylcholine,monoamines and their metabolites in ?-amyloid peptide(A?)_(1-40) treated rats and the potential mechanisms.Methods A 1-month NWK(15.5,31 and 62 mg?kg~(-1),respectively) administration to rats was performed daily after bilateral injection of A?_(1-40)(4 g?L~(-1) for each side) into hippocampus.Acetylcholine(ACh) was determined with an improved HPLC-ECD method,which is combined with two immobilized enzyme reactors.Monoamines and their metabolites were also determined with HPLC-ECD.Result Compared with shams,ACh and serotonin(5-HT) in whole brains in models decreased significantly(P
