【摘要】 目的研究党参多糖类成分的免疫活性和对造血功能的影响。方法分别采用DTH、血清溶血素抗体生成实验及内源性脾结节法、3H-TdR掺入骨髓有核细胞法,测定有关免疫指标及外周血Hb含量。结果党参多糖对体液免疫有较强促进作用,并在小剂量给药时对细胞免疫有促进作用;对溶血性血虚模型小鼠,能显著升高外周血Hb,并能促进60Co-γ射线照射后小鼠内源性脾结节生成,但对骨髓细胞DNA合成的促进作用不显著。结论党参多糖有免疫促进作用,并能促进脾脏代偿性造血功能。更多还原

【Abstract】 Objective To study the influences of polysacch arides(PS)from Radix Codonopsis on immune function and hematopoiesis in mice.Methods Several experiments have been condu cted for detecting delayed type hypersensitivity(DTH),hemolysin antibody concentration,endogenous spleen colony,3 H-TdRpermeate nuleated cells in bon e marrow.Results By oral administration,PS from Radix Codonopsis can promote the humoral immunity and PS at a small dosage en-hance the cellular immunity.PS from Radix Codonopsis can also elevate the hemoglobin cont ent of the hemolysis -induced blood -deficiency mice and increase the formation of endogenous spleen c olony,but has less effect on DNA synt hesis in the bone marrowof blood -deficiency mic e caused by 60 Co -γray.Conclusion PS from Radix Codonopsis can enhance the im-mune function and improve the compen satory hematopoiesis of spleen and t heir mechanisms need to be further studied.更多还原
