Rationale

Although few in vivo and in vitro studies have demonstrated the immunomodulatory effect of Gamma-oryzanol, but no human study is available regarding its effect on immunity. Therefore, the present study is designed to explore the effect of Gamma-oryzanol on immunity in healthy volunteers.

Objectives

1.      To compare the mean changes in the immunomodulatory parameters between the gamma-oryzanol and placebo groups from baseline to 60 days. These will include, Evaluation of the changes in baseline value of Th1 and Th2 cytokines (interferon-gamma and interleukin-4), IgA, IgG, IgM and IgE, baseline counts of T-cell (CD4+, CD8+), B-cell (CD19), TNF-alpha and NK-cells (CD16+, CD56+), IL-2, IL-4, IL-6, IL-8 and IL-10, serum cortisol and CRP levels between the groups

2.      To assess the safety of the Gamma-oryzanol as compared to the placebo group by estimation of Basic vital signs, Liver function tests, Kidney function tests, Thyroid function tests, and Lipid profile
