Figure 4.

Serum concentrations of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) after treatment of old female rats with EXD, its constituent fractions (EA, BU and WA) and premarin (PRE). The serum concentrations of TC, TG, HDL-C and LDL-C after EXD treatment; Data are presented in mean ± standard deviation (SD), n ≥ 3. The treatment denoted with * represents P < 0.05 in unpaired t-test compared with control group. Welch's correction was made for comparison with significantly different variances. Serum TC level: CTL vs EXD P = 0.0231, t = 2.204. Serum LDL-C level: CTL vs EXD P = 0.0473, t = 1.984
