    Abstract:
    Effects of Phytolacca acinosa polysaccharides I (PAP-I), 5 approximately 40 mg/kg in timing of 7 times/wk, 3 times/wk and 1 time/wk on their antitumor efficiency in Sarcoma-180 bearing mice were comparatively investigated. The results confirmed that PAP-I (10 mg/kg, 3 times/wk) reached its optimal antitumor efficiency. Concanavalin A-, lipopolysaccharides-induced lymphocyte proliferation and the IL-2 production were tested in normal mice which were treated with PAP-I, 5 approximately 50 mg/kg in timing of 1 time/wk and 3 times/wk. The results showed that PAP-I could augment lymphocyte proliferation and IL-2 production in the group treated with PAP-I in timing of once a week. However, in the group 3 times/wk, PAP-I could significantly weaken lymphocyte proliferation and IL-2 production. Further studies on IL-1, TNF and IL-6 secreted from macrophages and the level of CSF activity in serum of normal mice with different schedules showed that PAP-I (10 mg/kg, 3 time/wk) was the best one in regulating the production of IL-1, TNF, IL-6 and CSF activity. M-CSF was confirmed in the serum by using monoclonal antibody of IL-3, GM-CSF and polyclonal antibody of M-CSF. These results suggested that the antitumor effect of PAP-I, may be mainly related to its augmenting effect on macrophages in mice.
