TABLE 2.

Semi-quantification of TLR4-positive cells.

Group	TLR4-positive cells	Groups	TLR4-positive cells
Normal control	1.83 ± 0.31	Simvastatin	8.5 ± 0.99**
HFD	8.83 ± 0.6##	Simvastatin + fluoxetine	6.83 ± 1.01**
CUMS	17.33 ± 1.12##	Puerarin (30 mg/kg)	14.67 ± 1.20**
HFD/CUMS	22.50 ± 1.31##	Puerarin (60 mg/kg)	6.67 ± 0.84**
Fluoxetine	15.83 ± 0.87**	Puerarin (120 mg/kg)	3.83 ± 0.60**

The number of TLR4-positive cells was averaged from six random grids. Values are expressed as mean ± S.E.M (n = 6). ^## p < 0.01 vs. the normal control group; ^* p < 0.05 and ^** p < 0.01 vs. the HFD/CUMS group.
