LPS model group (M); LPS + chlorpromazine-positive (PL); LPS + high, medium and low doses of PME (CPHL, CPML and CPLL, respectively); LPS + water elution fraction of PME (WL); LPS + high, medium and low doses of the 50% ethanol elution fraction of PME (FHL, FML and FLL, respectively); LPS + high, medium and low doses of the 95% ethanol elution fraction of PME (NHL, NML and NLL, respectively); and LPS + TSG at high, medium and low doses (TSGHL, TSGML and TSGLL, respectively)
