Table 3.

Number of ChAT-positive cells in the hippocampus and corpus striatum

Groups	Hippocampus	Corpus striatum
Blank control	45.50±5.94	43.17±8.76
Model control	18.67±6.54*	24.00±3.02*
Electroacupuncture	42.67±9.57**	35.25±7.22**
L-dopa	40.25±6.82**	37.25±5.64**

^* P < 0.01, vs. Blank control group;

^** P < 0.01, vs. Model control group.

The number of ChAT-positive cells was significantly higher in the electroacupuncture and L-dopa groups than in the model control group. There was no significant difference in ChAT expression between the corpus striatum and hippocampus.
