Abstract

The purpose of this research was to investigate the effects of 50% ethylalcohol extracts of Lespedeza cuneata G. Don (LE) on the activity of murine immune cells. LE was administered orally once a day for 7 days at the dose of 250 mg/kg. LE increased the cell viability of thymocytes, splenocytes and peritoneal macrophages in vitro and in vivo system, but decreased the cell viability of thymocytes and splenocytes in the presence of concanavalin A in vivo system. Also, the administration of LE was increased the production of ${\gamma}$-interferone, but did not affect the production of interleukin-2 and interleukin-4. Furthermore, LE decreased the phagocytic activity of peritoneal macrophages in vitro and in vivo system, but enhanced the production of nitric oxide. These results suggest that LE has a immuno-regulative action via stimulation of immune cells proliferation.
