Objectives : Imyosan (IMS), a drug preparation comprised of Phellodendri Cortex (PC) and Atractylodis Rhizoma (AR), is commonly used as a traditional herbal medicine in Korea and China for the treatment of various inflammatory diseases. However, little is known about the effect of IMS and its component herbs on inflammatory mediators in RAW 264.7 cells. Therefore, in this study, methanol extracts of IMS and its component herbs were examined to determine if they inhibited inflammatory effects in RAW 264.7 cells. Methods : Cytotoxic activity of IJHT and its components on RAW 264.7 cells was using 5-(3-carboxymethoxyphenyl)-2H-tetrazolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression were detected by western blot. Results : Methanol extract of IMS and its component herbs were significantly reduced iNOS and COX-2 expression as well as NO, PGE2, $IL-1{\beta}$ and IL-6 production in RAW 264.7 cells. Conclusions : The results of this study indicated that the anti-inflammatory effect of Imyosan extract is more potent than that of extracts of its component herbs in macrophages.

Objectives: This study was evaluated to elucidate the inhibitory potential of Imyosan(IMS) and its components, Phellodendri Cortex(PC: Phellodendron amurense Rupr., Hwangbaek in Korean) and Atractylodis Rhizoma(AR: Atratylodes lancea D.C., Changchool in Korean), on human aortic smooth muscle cells(HASMC) migration and production of matrix metalloproteinase (MMP)-2 and MMP-9 by TNF-${\alpha}$ treatment. Methods: Cytotoxic activity of IMS and its components on HASMC was using 5-(3-caroboxy meth-oxyphenyl)-2H-tetra-zolium inner salt(MTS) assay. Effect of IMS, PC and AR on TNF-${\alpha}$-induced HASMC migration underside of matrigel filter was stained with hematoxylin-eosin. And total number of cells that migrated to the underside of the filter was counted. MMP-2 and MMP-9 activity was evaluated by gelatin zymography assay. Results: The matrigel migration assay showed that IMS effectively inhibited the TNF-${\alpha}$-induced migration of HASMC. Moreover, IMS significantly inhibited MMP-9 activity. Our present study demonstrates that IMS and its components inhibit TNF-${\alpha}$-induced HASMC migration and MMP-9 activity. The inhibitory effect of IMS extract is more potent than that of its component herb extracts. Conclusions: These results provide evidence that IMS has multiple effects in the inhibition of HASMC migration and may offer a therapeutic approach to block HASMC migration.

This study aimed to investigate the effects of each constituent-herb of Sagoonja- Tang on the plasma corticosterone level in mice exposed to cold stress. Sagoonja-Tang is composed of Ginseng Radix, Atractylodis Radix, Poria, and Glycyrrhizae Radix. Each constisuent-herb(0.5g/kg, 1.0g/kg) was administered intragastrically to mice 1hr prior to expose to forced cold water swimming($4{\circ}C$, 3min) before measuring the change of plasma corticosterone level of mice. The results were as follows: 1. At 30 minutes after the cold stress for 3 minutes the most significant increase of corticosterone level was shown. 2. Ginseng group(PGR group) didn't show any significant changes. 3. Atractylodis group(AR group) showed significant decrease at 0.5g/kg dose (P<0.01). But it didn't show significant changes at 1.0g／kg dose. 4. Poria group(P group) didn't show significant changes. But it showed slightly increase at 1.0g/kg dose. 5. Glycyrrhizae group(GR group) didn't show significant changes. These data revealed that Atractylodis macrocephalae Rhizoma might have the anti-stress effect through the control of plasma corticosterone level and the dose of herbs had a different effect on the plasma corticosterone level in mice exposed to cold stress.

Jeechool-Whan (JW) is a prescription of Ponciri Fructus Immaturus and Atractylodis Rhizoma Alba and improves the functions of the stomach and the spleen. Although it is said in Korean Medicine that the spleen and the stomach are the roots of the body's resistance, the meaning of 'improving the spleen and the stomach' is very comprehensive. Moreover, there are lots of drugs that are said to improve the spleen and the stomach, and the number of prescriptions using these drugs is huge. In this study, we focused on the new effect and mechanism of the JW on the ovalbumin (OVA)-induced allergic rhinitis (AR) model. The increased number of rubs and the increased levels of IgE and histamine in the OVA-sensitized mice were inhibited by JW administration. The balance of Th1/Th2 cytokine level was regulated by JW administration. The levels inflammatory proteins were decreased by JW administration in the nasal mucosa of the OVA-sensitized mice. Eosinophils and mast cells infiltration increased by OVA-sensitization was also decreased in the JW-administered mice. In addition, JW inhibited caspase-1 activity in the same nasal mucosa tissue. In activated human mast cells, JW inhibited the receptor interacting protein-2, I${\kappa}$B kinase-${\beta}$, nuclear factor-${\kappa}$B/Rel A, and caspase-1 activation. In conclusion, this study will be support the clear understanding of the concept of the spleen and the stomach in traditional Korean medicine as well as for a possibility of finding a cure for this AR in traditional medical treatments.
