Background and Objective : Chungsangboha-tang (CSBHT) has analgesic, sedative, anti-convulsive and anti-histamine effects, so it alleviates the symptoms of asthma. For the comparison of anti-inflammatory effect(s) on CSBHT, PD098059 was used as a negative control. Materials and Methods : This study emphasized THP-1 cells, which had been well characterized as a human monocytic leukemic cell line. The cells resemble monocytes with respect to several criteria and can be differentiated into macrophage-like cells by treatment with PMA. By using the MTS assay, it was possible to prove the safety of CSBHT. Results : Results shows that the CSBHT did not affected cell survival within $10^{1}$ ng/ml to $10^{5}$ ng/ml. Especially, $10^{5}$ ng/ml CSBHT treated cells show 70% deduction of $TNF-{\alpha}$ gene expression against that of LPS treated group. Furthermore, $IL-1{\beta}$, IL-6, IL-8, IL-10 and $TNF-{\alpha}$ levels are down-regulated when treated with CSBHT with concentrations up to 100 ug/ml on monocyte-derived macrophages. Interestingly, CSBHT-treated samples showed that overall transcriptional activities were down-regulated to 20% of that of PD098059 ($TNF-{\alpha}$ inhibitor). At protein level, the expression of $TNF-{\alpha}$ showed similar results as that of transcriptional activity. Results show that the protein level decreased more in the CSBHT-treated group (487 ${\pm}$ 87 pg/ml) than in the LPS-treated group (703 ${\pm}$ 103 pg/ml). In addition, the protein level of IL-8 in the CSBHT treated-group (9.84 ${\pm}$ 3.28 ng/ml) decreased similar as the expression of the control and PD098059-treated groups. Conclusion : CSBHT affects immune response, especially allergic responses and suppression of inflammatory reaction. The results provide us an alternative way to care for clinical inflammatory diseases, not only asthma but also the other possible general inflammatory and allergic diseases.

CSBHT is known to improve immunological response in mice and humans. In this study, CSBHT effect was examined in the context of CD4+ T cells' survival and TCR/CD3 induced activation responses. Spleen cells from 8 week BALB/c mice were cultured in CSBHT containing medium without activation for 24, 48 hr. The MTS assay and revealed that CSBHT did not stimulate spleen lymphocytes as mitogen. Spleen lymphocytes were treated with anti-CD3e/anti-CD28 antibodies for 48hr. Flow cytometry revealed that activity of T cell decreased with CSBHT concentration. CD4+ T cells were isolated and cultured ,in CSBHT containing medium for 48 hr. CSBHT did not affect survival of sorted CD4+ T cells without any involvement of APC. In order to evaluate the direct effect of CSBHT on helper T cells's proliferative capacity prior to activation, CD4+ T cells are isolated after 24hr of culture in CSBHT containing medium and activated with and without anti-CD3e/anti-CD28 activation for 48hr. A higher level of CD69 was observed in 1 ㎍/㎖ of CSBHT treatment than control using flow cytometry. But low CD69 expression was observed in 5㎍/㎖ of CSBHT treatment. Expression of mRNA for cytokines in CD4+ T cell revealed that IL-2 expression was increased in 1 ㎍/㎖. The expression of IL-2R α, INF- γ were increased with concentration. On the other hand mRNA of IL-4 was decreased in dose dependent manner. Results suggest that CSBHT may be desirable for CD4+ T cell's activity in immune responses. Further more, CSBHT may relatively activate Th1 and inactivate Th2.
