[Effects of traditional tibetan medicine, Fructus Lonicerae microphyllae on phagecytosis and cytokines production of murine macrophages].
OBJECTIVE
To explore the effects of traditional Tibetan medicine, Fructus Lonicerae microphyllae (FLM) on phagecytosis and cytokines production of murine macrophages.


METHODS
The phagecytosis of murine macrophages was analyzed by neutral red phagecytosis assay. The activities of IL-1 and TNF-alpha were measured by biological methods. The mRNA of TNF-alpha and INF-gamma expressed by macrophages was detected by RT-PCR.


RESULTS
The phagecytosis of murine macrophages was significantly enhanced by FLM at a concentration from 1 microg x mL(-1) to 100 microg x mL(-1) and the secretions of IL-1, and TNF-alpha from macrophages were markedly induced by FLM. Meanwhile, FLM also increased the expression of TNF-alpha mRNA and INF-gamma mRHA from macrophages in vitro.


CONCLUSIONS
FLM could promote phagecytosis and cytokines production of murine macrophages.
