title: Immunomodulating effects of fractioned polysaccharides isolated from Yu-Ping-Feng-Powder in cyclophosphamide-treated mice.
abstract: Yu-Ping-Feng-Powder (YP), a traditional Chinese medicine prescription, is widely applied in China for the cure and prevention of diseases related to immunodeficiency. To test whether the fractioned polysaccharides (YPF-P) isolated from YP have immunomodulating activities, the effects of YPF-P on cyclophosphamide (Cy)-treated mice were studied in relation to phagocytosis of macrophage, splenocyte proliferation, and humoral, and cellular immunity parameters. It was found that YPF-P enhances phagocytic activity, augments ConA- or LPS-stimulated T cell proliferation, increases the quantitative haemolysis of SRBC (QHS) and delayed-type hypersensitivity reaction (DTH) to dinitrofluorobenzene. Hence, YPF-P restored the immuno-competence suppressed by Cy. YPF-P also augmented IL-2 and IFN-gamma production, but failed to increase IL-4 production, which indicates that there is high probability that it enhance Th1 function. These results suggested that YPF-P has immunomodulating effects and that the polysaccharides constitute one of the active components of YP.
