To investigate the effects of icariine (ICA)on immumo-system,we observed the influence of ICA on concanavalin A (Con A)-primed murine spleen lymphocyte proliferation and colony stimulating factor (CSF)-like activity produced by Con A or lipopolysaccharides(LPS)-primed murine spleen lymphocytes by way of [3H]-TdR incorporation and bone marrow cells [3H]-TdR incorporation seperately. The results showed that ICA could significantly enhance Con A-induced mice lymphocyte proliferation in vitro; increased CSF-lik...
