a Timely changes of peripheral white blood cell (PWBC, × 109/L) during experimental process: intragastric administration with physiological saline, whole ingredients extract (WIE), water extract (WAE) or ultrafine powder (UFP) (twice daily, equalled to 1 g herb/kg/day) for 18 days with cyclophosphamide (Cy, 80 mg/kg/day) injected intraperitoneally from days 12 to 14. b PWBC level at Day 19. c Serum IgG and d serum IgM levels in different groups of mice. Data are expressed as mean ± S.D. of six mice. ###p < 0.001 vs Control; *p < 0.05, **p < 0.01 and ***p < 0.001 vs Cy; Δp < 0.05 and ΔΔp < 0.01 vs WIE
