Effect of Yupingfeng Polysaccharide on Serum IL-2 and IFN-γ Levels in Immunosuppressive Mice

[Objective] The paper was to discuss regulation and protection effect of Yupingfeng polysaccharide （YPF-P） on immunosuppressive mice. [Method] Taking immunosuppressive mice induced by 80 mg/kg cyclophosphamide as test animal model, effects of different doses （100,200 and 400 mg/kg） of YPF-P on spleen index, serum IL-2 and IFN-γ levels of mice were studied. [ Result] High dose of YPF-P （400 mg/kg） could improve the spleen index of immunosuppressive mice （P 〈0.05）. YPF-P could enhance serum IL-2 and IFN-γ levels of immunosuppressive mice, and the effects in middle-dose group and low-dose group were better. YPF-P could significantly increase serum IL-2 level of normal mice （ P 〈 0.01 ）, but it had no significant effect on serum IFN-γ level of normal mice. [ Conclusion] The research provides an experimental basis for clinical application of YPF-P.

从沙溪复兴工程看云南传统村落的可持续发展

传统村落是中国传承优秀历史文化的载体,也是中国物质文明、精神文明的重要体现。在中国经济社会不断发展的今天,传统村落的发展也在逐渐发生着变化,例如传统村落同质化的出现以及资源的过度开发等现象的出现,这对于中国来说都是物质文明、精神文明的一种损失。因此,对传统村落的可持续发展的研究也显得尤为重要。沙溪复兴工程以文化遗产保护为切入点进行传统村落的可持续发展研究。
