Immune-Enhancing Activity of Vitis coignetiae Extract via Increasing Cytokine and Natural Killer Cell Activity in Splenocytes and Cyclophosphamide-Induced Immunosuppressed Rats
Figure 7
Effect of Vitis coignetiae extract (VCE) on the serum levels of immune-related cytokines in the serum of cyclophosphamide (Cy)-induced immunosuppressed rats. Wistar rats were treated with saline, Cy (5 mg/kg/d), oral VCE (0, 50, 250, and 500 mg/kg/d), and HemoHIM (positive control; 1,000 mg/kg/d) once daily for four weeks, after which serum levels of (a) tumor necrosis factor (TNF-α), (b) interferon gamma (IFN-γ), (c) interleukin-2 (IL-2), (d) IL-12, (e) immunoglobulin G (IgG), and (f) IgM were quantified using enzyme-linked immunosorbent (ELISA) kits. Bars labeled with different superscripts have significantly different values ().
