Abstract:
Objective To compare the immunopotentiating effects of polysaccharides extracted from wild/cultivate Cistanehe deserticola (WCDPS/CCDPS) in Xinjiang. Methods ICR mice were subcu-taneously injected twice with different doses(low,medium and high) of WCDPS and CCDPS in combination with ovalbumin (OVA). OVA-specific antibody IgG,as well as IgG1 and IgG2a subtypes, was determined by ELISA. OVA-specific lymphocyte proliferation was measured by MTT. Expression of CD4+T and CD8+T cells was analyzed by flow cytometry. Results Both WCDPS and CCDPS could significantly improve the production of OVA-specific IgG,IgG1 and IgG2a,promote the proliferation of OVA-specific lymphocytes and increase the expression of CD4+T and CD8+T cells(all P<0.05) with no significant difference between them at the same dosages (P>0.05). WCDPS and CCDPS had no influence on the body weight of mice after im-munization. Conclusion WCDSP and CCDPS could significantly enhance the OVA-specific humoral and cellular immune responses with no statistical difference and are characterized by high safety.
