Objective: The purpose of this research is to examine the effects of Mahaenggamseok-tang-gagambang (MGTG) on CD3+ T cells, CD4+ T cells and CD8+ T cells in ovalbumin (OVA)-induced asthmatic mice. Methods: C57BL/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (four a week) for asthma induction. Two experimental groups were treated with different concentrations of MGTG (400 mg/kg and 200 mg/kg) extract and cyclosporin A (10 mg/kg) for the later 8 weeks. At the end of the experiment, the mice lung was removed and analyzed CD3+ T cells, CD4+ T cells and CD8+ T cells by flow cytometer. Results: Numbers of CD3+ T cells in lung of the MGTG groups (200, 400 mg/kg) were significantly decreased compared with that of control group. Numbers of CD4+ T cells in lung of the MGTG groups (200, 400 mg/kg) were significantly decreased compared with that of control group. Numbers of CD8+ T cells in lung of the MGTG groups (200, 400 mg/kg) were significantly decreased compared with that of control group. Conclusion: The results of this study suggest that MGTG alleviated asthmatic hyperreactiviry through CD4+ and CD8+ T cells. Further study of relative cytokines is expected.

The purpose of this research is to evaluate the effect of Mahaenggamseok-tang-gagambang (MGTG) on airway hyper- responsiveness (AHR), immune cells, cytokines and lung tissue in OVA-induced asthmatic mice. C578L/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (3times a week) for asthma sensitization and challenge. Two experimental groups were treated with different concentrations of MGTG (400 mg/kg and 200 mg/kg) extract and cyclosporin A (10 mg/kg) for the later 8 weeks. Enhanced pause (Penh) levels were measured by whole body plethysmography. Immune cells were analyzed by flow cytometer in peripheral blood monocyte cell (PBMC) and lung cells. The IL-1b, IL-12, IFN-${\gamma}$, OVA-lgE, IL-4, IL-5, TNF-${\alpha}$ were analyzed by ELISA kit in serum and splenocyte+a-cCDS/a-CD28. Enhanced pause (Penh) levels of the MGTG groups (400 mg/kg and 200 mg/kg) were decreased significantly compared with that of control group. The numbers of MGTG groups (400 mg/kg and 200 mg/kg) on lung total cells were decreased significantly compared with that of control group. The numbers of MGTG groups (400 mg/kg and 200 mg/kg) on $CD3^+/CD69^+$, $B220^+/CD22^+$, $B220^+/CD23^+$, $B220^+/lgE^+$, $CCR3^+$ cells were decreased significantly compared with that of control group. The number of MGTG group (400 mg/kg) on $CD3^+/CD49b^+$ cells was decreased significantly compared with that of control group. The level of MGTG groups (400 mg/kg and 200 mg/kg) on IL-4, IL-5, IL-12, TNF-${\alpha}$, OVA-lgE were decreased significantly compared with that of control group. The level of MGTG group (400 mg/kg) on IL-1b, IL-1S, OVA-lgE were decreased significantly compared with that of control group. These results demonstrate that MGTG could be a desirable alternative therapy for allergic asthma by inhibiting the expression of immune cells, the activation of inflammatory mediator.
