Table 1. Effect of ACG on brain cholinesterase activity in Aβ (25–35)-treated mouse brain

Group	Dose (mg/kg)	Cholinesterase activity (μmol/h/mg protein)
Sham	-	5.1 ± 0.3
Aβ (25–35)	15 nmol/animal	9.3 ± 0.5##
+ ACG	10	8.8 ± 0.2
+ ACG	25	7.5 ± 0.2**
+ ACG	50	7.2 ± 0.3**

Cholinesterase activities in mouse brain homogenates were measured after the passive avoidance test retention trial. Values are expressed as the means ± S.E.M. of acetylthiocholine concentrations hydrolyzed by cholinesterase preparation of brain homogenate for 1 h (n = 6 mice/group).
p<0.01 vs. sham control,
p<0.01 vs. 15 nmol Aβ (25–35) control.
