Effects of Water Extract Acorn on Mouse Immune Cell Activation Ex Vivo

Acorns have been used as a traditional remed as well as food source. However, few studies on their immunomodulating effects have been reported. In this study, the combined immunomodulative effect of a water extract of acorns was tested on seven to eight weeks old mice(balb/c). The mice were fed ad libitum on a chow diet, and a water extract of the plant mixture was orally administered every other day for four weeks at two different concentrations(50 and 500 mg/kg B.W.). The production of cytokine(IL-$1{\beta}$, IL-6, IL-2, IL-10, IFN-$\gamma$), secreted by macrophages stimulated with LPS or not, detected by ELISA assay using cytokine kit. After 48 h of incubation with mitogen(ConA or LPS) ex vivo study showed that cytokine (IL-$1{\beta}$, IL-6, IL-2, IL-10, IFN-$\gamma$) was detected in both of the 50 and 500 mg/kg B.W. supplementation groups with LPS stimulation. The results of this study may suggest that supplementation with acorn water extract increase immune function by regulating cytokine production capacity by activated macrophages.
