Deficits in glucose, impaired insulin signalling and brain insulin resistance are common in the pathogenesis of Alzheimer's disease (AD); therefore, some scholars even called AD type 3 diabetes mellitus. Curcumin can reduce the amyloid pathology in AD. Moreover, it is a well-known fact that curcumin has anti-oxidant and anti-inflammatory properties.

Objective: To observe the changes in Aβ40, Aβ42 and ADDLs in brains of 3 month-old APPswe/PS1dE9 double transgenic mice after six-month intervention with curcumin, in order to discuss the neuroprotective effect of curcumin.

Method: APPswe/PS1dE9dtg mice were randomly divided into the model group, the Rosiglitazone group (10 mg x kg(-1) x d(-1)) and curcumin high (400 mg x kg9-1) x d(-1)), medium (200 mg x kg(-1) x d(-1)) and low (100 mg x kg(-1) x d(-1)) dosage groups, with C57/BL6J mice of the same age and the same background in the normal control group. After 6 months, the immunohistochemical staining (IHC) and the Western blot method were used to observe the changes in positive cell of Aβ40, Aβ42 and ADDLs in hippocampal CA1 area, their distribution and protein expressions.

Objective: To observe the effect of curcumin on the expressions of AKT (serine-threonine kinase, AKT, also known as PKB) and p-AKT (phosphated serine-threonine kinase, p-AKT) in APP/PS1 double transgenic mice of the AD model.

Method: Three-month-old APP/PS1 double transgenic mice were randomly divided into the model group, the rosiglitazone (10 mg kg-1 . d-1) group, and high (400 mg .

Objective: To observe the effect of curcumin on the expression of PI3K (phosphatidylinositol-3-kinase, PI3K) and p-P3 K (phosphated phosphatidylinositol-3-kinase, p-PI3K) in the hippocampus of Alzheimer's disease (AD) model (APP/PS1 double transgenic) mice.

Method: A total of 60 three-month-old APP/PS1 double transgenic mice were randomly divided into model group, rosiglitazone group(10 mg . kg-1 .
