Abstract:

To evaluate the immune activation and reactive oxygen species scavenging activity of Cordyceps militaris polysaccharides (CMP) in vivo, 24 male and 24 female Kunming mice were randomly divided into four groups. The mice in the four experimental groups were administered 0 (normal control), 50, 100, or 200mg/kg/d body weight CMP via gavage. After 30 days, the viscera index, leukocyte count, differential leukocyte count, immunoglobulin (IgG) levels, and biochemical parameters were measured. The effect of CMP on the expression of tumor necrosis (TNF)-α, interferon (IFN)-γ, and interleukin (IL)-1β in the spleens of experimental mice was investigated by real-time polymerase chain reaction. The results showed that the administration of CMP improved the immune function in mice, significantly increased the spleen and thymus indices, the spleen lymphocyte activity, the total quantity of white blood cells, and IgG function in mice serum. CMP exhibited significant antioxidative activity in mice, and decreased malondialdehyde levels in vivo. CMP upregulated the expression of TNF-α, IFN-γ, and IL-1β mRNA in high-dose groups compared to that observed for the control mice. We can thus conclude that CMP effectively improved the immune function through protection against oxidative stress. CMP thus shows potential for development as drugs and health supplements.
