  Purpose

The investigators performed a 12-week, randomized, double-blind, placebo-controlled human trial to evaluate the efficacy and safety of Cauliflower Mushroom extract on promotion of immunity. The investigators measured promotion of immunity parameters , including Cytotoxicity, Cytokine (IL-4, IL-10, IFN- γ, TNF-α), and CBC (WBC, RBC, Hb, Hct, MCV, MCH, MCHC, PLT), and monitored their blood pressure.

Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Prevention

Further study details as provided by Chonbuk National University Hospital:

Primary Outcome Measures:
  • Changes in Cytotoxicity [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
    Cytotoxicity was measured in study visit 1(0 week) and visit 3(12 week). cytotoxicity was measured by NK cell activity. Cytotoxicity (%) = (experimental release - spontaneous release) / (maximum release - spontaneous release) x 100

  • Changes in Cytokine (IL-4, IL-10, IFN- γ, TNF-α) [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
    Cytokine (IL-4, IL-10, IFN- γ, TNF-α) was measured in study visit 1(0 week) and visit 3(12 week).


Secondary Outcome Measures:
  • Changes in CBC (WBC, RBC, Hb, Hct, MCV, MCH, MCHC, PLT) [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
    CBC (WBC, RBC, Hb, Hct, MCV, MCH, MCHC, PLT) was measured in study visit 1(0 week) and visit 3(12 week).
