Abstract

Polygonum cuspidatum is a natural plant that is used in traditional Chinese herbal medicine. The crude extract of Polygonum cuspidatum (CEPC) has numerous biological effects; however, there is a lack of studies on the effects of CEPC on immune responses in normal mice. The aim of the present study was to determine the in vivo effects of CEPC on immune responses in normal mice. CEPC (0, 50, 100, 150 and 200 mg/kg) was orally administered to BALB/c mice for three weeks, following which blood, liver, and spleen samples were collected. CEPC did not significantly affect the total body weight, or tissue weights of the liver or spleen, as compared with the control mice. CEPC increased the percentages of CD3 (T‑cell marker), 11b (monocytes) and Mac‑3 (macrophages) positive‑cells, and reduced the percentage of CD19‑positive cells (B‑cell marker), as compared with the control mice. CEPC (100 mg/kg) stimulated macrophage phagocytosis of blood samples but did not affect macrophage phagocytosis in the peritoneum. Activity of the splenic natural killer cells was increased in response to CEPC (50 mg/kg) treatment. Furthermore, CEPC inhibited T‑ and B‑cell proliferation when the cells were stimulated with concanavalin A and lipopolysaccharide, respectively.
