[Effect of forsythia suspense extract on phagocytosis of peritoneal macrophages and NO production in vitro].

Aim: To investigate the effect of forsythia suspensa (FS) extract on phagocytosis of peritoneal macrophages and NO production in vitro.

Methods: The peritoneal macrophagess were isolated from BALB/c mice. After stained with CFDA-SE, the DH5alpha were co-cultured with peritoneal macrophagess for 3 h.

[Effects of Forsythia suspense extract on cell proliferation and activation of the mouse T lymphocytes in vitro].

Aim: To investigate the effect of Forsythia suspensa (FS) extract on the activation and proliferation of the mouse T lymphocytes in vitro as well as its immunosuppressive effect.

Methods: The lymphocytes were isolated from the lymphoid nodes of BALB/c mice. Fluorescence conjugated monoclonal antibodies and flow cytometry were used to detect the expression of CD69, CD25 and CD 71 of the activated T lymphocytes in vitro in response to Concanavalin A (ConA).
