Objective : Pamooltang (PM) and Sipjeondaebotang (SC) are used in Korea to treat many diseases such as sterility, menstrual disorder, and general prostration. We made a comparative study of PM and SC which are different in component ratio between Astragalus membranaceus BUNGE (AC) and Cinnamomum cassia PRESL. (CC). Methods : Anti-oxidation was studied by 1.1.-diphenyl-2-picrylhydrazyl (DPPH) assay and anti-inflammation was investigated by prostaglandin $E_2;(PGE_2)$ and nitric oxide (NO) inhibition assay. For immune response activities, this study used NO synthesis on RAW 264.7 cells and splenocyte proliferation. Results : The results showed that PM and SC components had no significant effect of anti-oxidation or anti-inflammation. However, we observed their effects upon inducible NO synthesis in Raw 264.7 cells. The SC2 stimulated NO synthesis $11.42pm1.36{mu}M$ (control; $0.89pm0.00{mu}M$). PM and SC components had the effect of immune response which in a dose-dependent manner significantly induced the splenocyte proliferation. The splenocyte proliferation induced by SC2 was higher than others at the concentration of 1, 10, 100, 1000 and 2000 ${mu}g/ml$. The SC8 was shown to up-regulate IgG, 100 ${mu}g/ml$ 3.3 times, 1000 ${mu}g/ml$ 2.6 times as a control. Conclusions : These results may have important implications for our understanding of the ratios of AC and CC in SC.
