Systemic insulin resistance measured by intraperitoneal insulin tolerance test. After 6 h of food deprivation, serum glucose levels were measured at an assigned time after intraperitoneally insulin injection. (A) Changes of serum glucose concentrations. (B) The area under the curve (AUC) of glucose calculated in the first (0–30 min) and second phases (30–90 min). AD-Con fed 45% fat diet with 0.5% dextrin in AD rats infused intra-CA1 infusion of amyloid-β(25–35), AD-TTK fed 45% fat diet with 0.5% water extract of Tetragonia tetragonioides (TTK) in AD rats, and Normal-Con fed 45% fat diet with 0.5% dextrin in non-AD rats infused intra-CA1 infusion of amyloid-β(35–25). Each dot and bar represent Mean ± SD (n = 10). # Significantly different among the groups in one-way ANOVA at p < 0.05 and ## p < 0.01. * Significantly different from AD-Con at p < 0.05 and ** p < 0.01 in the Tukey test. † Significantly different from the Normal-Con at p < 0.05 in the Tukey test.
