Table 1.

Concentration of total cholesterol (TC) in the serum, cortex, and hippocampus of rabbits fed a control diet, high-cholesterol diet, and high-cholesterol diet plus simvastatin.

Group	Serum TC	Cortex TC	Hippocampus TC
Control diet	51.4 ± 9.96b	1.29 ± 0.16	1.36 ± 0.14
Cholesterol diet	1449.6 ± 677.1	1.25 ± 0.13	1.31 ± 0.23
Cholesterol diet + simvastatin	866.1 ± 147.46a	1.27 ± 0.11	1.38 ± 0.10

The concentration of total serum cholesterol is expressed as g/mL and the concentration of total cortex or hippocampus cholesterol is expressed as g/100 g wet weight of tissue. Data are expressed as means ± S.D. (n = 8;  ^a P < 0.05;  ^b P < 0.01; compared with Cholesterol diet).
