Gamisaenghyeolyunbueum (GSYE) is a traditional Oriental herbal medicine prescription, which has been used for the treatment of various allergic disorders, atopic dermatitis, extravasated bleeding from skin, especially skin related disease. The author investigated the effects of GSYE on mast cell-mediated allergic inflammatory reactions. GSYE dose-dependently (0.01-1 g/kg) inhibited compound 48180-induced systemic anaphylactic shock and ear swelling response. The inhibitory effect of GSYE on the histamine release from rat peritoneal mast cells induced by compound 48f80 reveals significantly (p<0.05) at concentrations ranging from 0.01 to 1 mg/ml in a dose-dependent manner. GSYE also inhibited the passive cutaneous anaphylaxis(PCA) by oral administration at 1 g/kg. In addition, GSYE dose-dependently (0.01-1 g/kg) inhibited the phorbol 12-myristate 13-acetate(PMA) and A23187-induced tumor necrosis $factor-{\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that GSYE may be a beneficial applicability in the allergic-related diseases.
Analysis of the Root Nodule-enhanced Transcriptome in Soybean

For high throughput screening of root nodule-enhanced genes, cDNA libraries specific for three different developmental stages of soybean root nodules were constructed after inoculation with Bradyrhizobium japonicum USDA110. 5,469 cDNA clones were sequenced and grouped into 2,511 non-redundant (nr) ESTs consisting of 769 contigs and 1,742 singletons. Using similarity searches against several public databases we constructed a functional classification of the ESTs into root nodule-specific nodulin genes, stress-responsive genes and genes related to carbon and nitrogen metabolism. We also constructed a cDNA microarray with 382 selected clones that appeared to be up-regulated in the root nodule. Using the microarray we compared the transcript levels of uninfected roots and root nodules from four developmental stages. We identified 81 genes that were differentially expressed, and grouped them into seven clusters according to the similarity of their expression profiles, using a hierarchical clustering algorithm. Clusters 1, 2, 3, and 6, comprised of 58 genes, showed root nodule-enhanced expression. The information from this study will be used to analyze the roles of root nodule-specific genes and signaling pathways during root nodule development.
