Abstract
Objective: The purpose of this study was to investigate the effect of Hwanggigunjungtang(HGT) on white rats with deteriorated immunity caused by methotrexate. Methods: First, methotrexate was fed to the white rats once a day for 4 days. After the immune responses of the rats are deteriorated, dried extracts of HGT mixed in water was fed to the rats once a day for 14 days. And then we measured the percentage of B-cell and T-cell in peripheral blood, the percentage of CD3+CD4+ T-cell and CD3+CD8+ T-cell of blood sampled from spleen and peripheral region. Results: The percentage of B-cell of peripheral blood was not different statistically. The percentage of T-cell of peripheral blood was increased significantly in HGT group as compared with control group. The percentage of CD3+CD4+ T-cell of peripheral blood was increased significantly in HGT group as compared with control group. The percentage of CD3+CD8+ T-cell of peripheral blood was decreased in HGT group as compared with control group. The percentage of CD3+CD4+ T-cell of spleen was increased significantly in HGT group as compared with control group. The percentage of CD3+CD8+ T-cell of spleen was not different statistically. Conclusion: According to the above results, HGT has an effect of increasing immune responses on white rats with deteriorated immunity caused by methotrexate.
