Objective To explore the mechanism of immunoregulation by investigating the effects of polysaccharides from Millettia speciosa Champ (MSC) on proliferation of spleen lymphocyte and secretion of cytokine in mice.Methods The effects of MSC polysaccharides on Con A-induced spleen T lymphocyte proliferation were determined by MTT.The contents of TNF-α, IL-6 and PGE2 were determined by ELISA.Results The Con A-induced T lymphocyte proliferation was significantly increased by MSC polysaccharides at the concentrations from 50 to 200 μg·mL-1.Coupled with TNF-α and IL-6 were significantly increased while PGE2 was significantly decreased.Conclusion MSC polysaccharides could increase proliferation of spleen lymphocyte and enhance the immune responses by increasing the secretion of TNF-α and IL-6 in mice.

Objective To purify and rejuvenate the plant of Curcama kwangsiensis,improve the transplantation survival rate of cultivars,and make the convenience of storagement and management for the cultivars production.Methods The rhizome plantlet formation of C.kwangsiensis was induced by regulating both of macro-element and sucrose concentration in the MS culture medium.Results Both of them were very important influence factors on the rhizome plantlet formation of C.kwangsiensis.Media 1/2 MS and 6% sucrose were adaptable to the rhizome plantlet formation of C.kwangsiensis,had the best effects on the formation rate of the rhizome plantlet,diameter and direct transplanting rate of the rhizome plantlet.Both plantlet and root system development were stronger.Conclusion In the present research,it is successful in inducing the rhizome plantlet formation of C.kwangsiensis.
