Abstract:

Objective: To observe immune regulation function of selenium-enriched barley seedling (SEBS) in mice by detecting cell-mediated immunity and humoral immunity. Methods: Experimental mice were orally administered with SEBS at doses of 1, 0.5 g/ml and 0.1 g/ml. Meanwhile, two groups were also orally administered with saline water at the same volume and regular barley seedling at the dose of 1 g/ml as the controls. Total number of white blood cell (WBC), phagocytosis test of macrophage on abdominal cavity, titer of antibody, number of antibody-producing cells and weight of immune organs in mice were determined. Results: Compared to saline water group, SEBS could significantly improve phagocytic function of macrophages (P<0.01), obviously increase the titer of anti-CRBC antibody (P<0.05), spleen index (P<0.05), and total number of WBC (P<0.05). Conclusion: SEBS can promote cell-mediated immunity and humoral immunity in mice in a dosedependent manner.
