Objective: To study on Radix Hedyseri as substitute for Radix Astragali of Yupingfeng oral liquid on cellular immunity in immunosuppressed mice.
Methods: The model of immunosuppression mice were induced by Cyclophosphamide. And the same dose of Radix Hedyseri and Radix Astragali alternative Yupingfeng oral liquid was intragastric administrated into mice; Antagonistic experiments were observed in vivo. Determined the thymus gland index, spleen index, phagocytosis of the macrophage, proliferation index of T lymphocyte, kill and wound activity, T lymphocyte subgroup, and content of IL-13 of serum.
Results: Yupingfeng oral liquid and Yuping-feng aqueous extract of Radix Hedyseri substitute Radix Astragali both could significant raise thymus gland index and spleen index, and clearly increase the phagocytosis of the macrophage. They both could antagonize immunosuppressive action caused by Cyclophosphamide, which could promote T lymphocyte proliferation, kill and wound activity, quantity of T lymphocyte subgroup, and production of IL-1beta with different degree. And Yupingfeng aqueous extract of Radix Hedyseri substitute Radix Astragali increased spleen index and T lymphocyte proliferation was better than those of Yupingfeng oral liquid.
Conclusion: Radix Hedyseri and Radix Saposhnikoviae, compatible with Rhizoma Atractylodis Macrocephalae compared with Yupingfeng oral liquid in cell immunity regulation has a similar role, and better in the recovery of spleen weight and T cell proliferation.
