[Comparative study of Hedysari Radix and Astragali Radix alternative classic tonification prescriptions on humoral immunity in immunosuppressed mice].

OBJECTIVE
To compare the regulating effects of Hedysari Radix and Astragali Radix alternative classic tonification prescriptions on humoral immunity in immunosuppressed mice.


METHODS
The immunosuppressed mouse model was induced by cyclophosphamide. The mice were administered intragastically with same dose of Hedysari Radix and Astragali Radix alternative Buzhong Yiqi Yiqi Yangxue,Yupingfeng oral liquid and Fuqi Zhihan granules for antagonistic experiments in vivo. And spleen index, HC50, CD19+B lymphocyte subgroup and content of serum IL-4 were determined after treatment.


RESULTS
Both groups of Hedyseri Radix and Astragali Radix could antagonize immunosuppressive action caused by cyclophosphamide. They both could significantly raise spleen index, HC50, CD19+ B lymphocyte subgroup and content of serum IL4 in different degree. And Yupingfeng aqueous extract of Hedysari Radix substitute Astragali Radix was better than Yupingfeng oral liquid in raising spleen index. There were no significant differences among the rest Hedysari Radix and Astragali Radix alternative groups.


CONCLUSION
Hedysari Radix compatibility with other drugs compared with original prescription has similar role in humoral immunity regulation.
