Objective: To compare the effects of the same compound (Yiqi Yangxue decoction and Buzhong Yiqi decoction) prescription containing Astragali Radix (AR) and Hedysari Radix (HR)

respectively

on immunologic functions of mice. Method: The sixty mice were divided randomly into six groups:the control group

the model group

Yiqi Yangxue decoction containing AR group

Yiqi Yangxue decoction containing HR group

Buzhong Yiqi decoction containing AR group and Buzhong Yiqi decoction containing HR group. The mice were injected peritoneally with cyclophosphamide to establish immunosuppressive model

and spleen lymphocyte Proliferation

IL-1

IL-4 and serum hemolysin level

NK cells activity were observed Result: Afteradministration

the immunologic functions were significantly increased. The compounds congtaining HR were more significant than compounds containingg AR in spleen lymphocyte proliferation

but in other respects

the two compounds whether congtaining AR or HR had no obvious diffference. Conclusion: Both Yiqi Yangxue decoction and Buzhong Yiqi decoction containg HR are better thancompouds congtaining AR in improving cellular immune function.
