  • Objective : Airway inflammation is now regarded as a defining feature of asthma. The importance of eosinophits in the airway inflammation of asthma patients is widely recognized, and eosinophils mobilization in the respiratory epithelium is activated by chemoattractants and cytokines. This study was designed to examine the extent of the ability of Moutan Cortex Radicis to inhibit eosinophil chemotaxis of pulmonary epithelium after allergic stimulation. Material and Methods : Water extracts of Moutan Cortex Radicis and pulmonary epithelial cell lines A549(human type II-like epithelial cells) and human eosinophils were used. Cytotoxic effects of Moutan Cortex Radicis were estimated via MTS assay, and the effects of Moutan Cortex Radicis on chemokines from prestimulated A549 cells were estimated by sandwich ELISA and RT-PCR. Chemotaxis assay on prestimulated eosinophils treated with Moutan Cortex Radicis. was conducted Result : In this study we demonstrated that $TNF-{\alpha}$ and IL-4, $IL-1{\beta}$ induced the accumulation of chemokines' mRNA in the pulmonary epithelial cell lines A549 in a dose-dependent manner. Chemokines of eotaxin, ICAM-1, YCAM-1, IL-8, IL-16 were inhibited by Moutan Cortex Radicis in a dose dependent manner, but RANTES showed no inhibition due to Moutan Cortex Radicis. Eosinophil migration was inhibited at high concentrations of Moutan Cortex Radicis. Conculusion : These findings are indicative of supression of chemokines accomplished by Moutan Cortex Radicis treatment, demonstrating the potential therapeutic value of Moutan Cortex Radicis for treating diseases such as asthma.

  • This study was conducted to investigate desirable storage method to major chinese herbal medicine materials, Moutan Radicis Cortex in different packing materials and sealing degree. The loss in weight of Moutan Radicis Cortex as influenced by packing materials was the lowest at complete sealing treatment with transparent or black polyethylene film. The rot ratio of Moutan Radicis Cortex during the storage period was not difference between packing materials, transparent and black polyethylene film, but rot ratio of complete sealing condition was lower than punch ($\phi$J5mm) on polyethylene film.

  • Moutan cortex, the root bark of Paeonia suffruticosa Andrews (Paeoniaceae), has pharmacological effects such as anti-inflammatory, antiallergic, analgesic and antioxidant activities. We investigated a methanol extract of Moutan cortex for neuroprotective effects on neurotoxicity induced by amyloid ${\beta}$ protein ($A{\beta}$) (25-35) in cultured rat cortical neurons. Exposure of cultured cortical neurons to $10\;{\mu}M\;A{\beta}$ (25-35) for 24 h induced neuronal apoptotic death. Moutan cortex inhibited $10\;{\mu}M\;A{\beta}$ (25-35)-induced neuronal cell death at 30 and $50\;{\mu}g/m{\ell}$, which was measured by a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assay and Hoechst 33342 staining. Moutan cortex inhibited $10\;{\mu}M\;A{\beta}$ (25-35)-induced elevation of intracellular calcium concentration ($[Ca^{2+}]_i$), and generation of reactive oxygen species (ROS) which were measured by fluorescent dyes. Moutan cortex also inhibited glutamate release into medium induced by $10\;{\mu}M\;A{\beta}$ (25-35), which was measured by HPLC. These results suggest that Moutan cortex prevents $A{\beta}$ (25-35)-induced neuronal cell damage by interfering with the increase of $[Ca^{2+}]_i$, and then inhibiting glutamate release and ROS generation. Moutan cortex may have a therapeutic role in preventing the progression of Alzheimer's disease.

  • Objectives : The goal of this study was to investigate the effect of Moutan Cortex as antidepressant in forced swimming test(FST) model. Methods : The expressions of corticotropin-releasing Factor(CRF), c-Fos and tyrosine hydroxylase(TH) were measured with immunohistochemical method at paraventricular nucleus (PVN), locus coeruleus(LC) and ventral tegmental area(VTA). Results : The duration of immobility in the forced swimming test was significantly decreased in the Moutan Cortex 100 mg/kg treated group in comparison with the control group(p<0.01). CRF and c-Fos expressions at PVN were decreased in the Moutan Cortex 100mg/kg treated group in comparison with the control group. But only the expression of c-Fos was shown the significance(p<0.05). TH expressions at LC and VTA were significantly decreased in the Moutan Cortex 100mg/kg and 400mg/kg treated group in comparison with the control group(p<0.001). Conclusion : According to the results, Moutan Cortex has the antidepressant effect by showing the reduced immobility through the reduction of c-Fos expression at PVN and the reduction of TH expression at LC and VTA.

  • The application of PCR analysis on the herbal medicine Moutan Cortex (Paeonia suffruticosa Andrews) was evaluated by the comparison of the genetic relationship based on the DNA sequence with Paeoniae Radix (Paeonia lactiflora Pallas) following development of specific primers. Moutan Cortex and Paeoniae Radix were distinguished through the PCR analysis based on the internal transcribed spacer (ITS-PCR) from nuclear ribosomal DNA region. The 294 bp PCR products both of Moutan Cortex and Paeoniae Radix was amplified by MIF1 and MIR1. And a Moutan Cortex specific 225 bp PCR amplification product was amplified by MIF2 and MIR1 primers. The 225 bp sequence could be successfully amplified from Mortan Cortex of dried herbal preparations. PCR analysis based on ITS (ITS-PCR) may be an efficient tool for the discrimination of Moutan Cortex.

  • Objective : This study was carried out for the purpose of proving the effect of anti-allergic efficacy on B cells and the mast cells of the BALB/C mouse by the abstraction from a Moutan cortex. Methods & Results : In order to know what the effect of an abstraction from Moutan cortex and about the expression of CD23 and IgE, IC-2 cell (mouse mast precursor cells that was dependent on IL-3), it was necessary to be activated. We then analyzed it from the flow of cytometry on the increase and the divorce of the B cells activated by anti-CD40. In order to know what the effect of it was on the organization of cytokine gene expression from the increase and divorce of the B cells and allergic acting by Moutan cortex, we found it necessary to examine the IC-2 cells and B cells. At the same time, as we examined the histamine release of IC-2 cells by ELISA method, we also examined the effect of Moutan cortex on the increase and divorce of the B cells by 3H-thymidine uptake method. We then analyzed the release of IL-4, IgE and histamine. Conclusions : As a results, Moutan Cortex promoted blood supply by extending the blood vessel of nasal mucous, which was contracted by the hypertrophied nasal mucous.

  • Objective & Methods : The present study was to investigate the effect of Moutan Cortex Radicis Herbal-acupuncture (MCR-HA) at GB34 (Yangleungchean) on hyperlipidemia and arteriosclerosis induced by high fat diet in rats. Results : 1. Moutan Cortex Radicis herbal-acupuncture infusion solution (MCR-HAS) increased DPPH radical scavenging activity and HMG-CoA reductase inhibition rate in rat liver cells. 2. MCR-HA at GB34 decreased serum total cholesterol level, and increased serum phospholipid/total cholesterol in rats with high fat diet. 3. MCR-HA at GB34 decreased atherogenic index in rats with high fat diet. 4. MCR-HA at GB34 increased hepatic catalase activity in rats with high fat diet. Conclusion : These results suggested that Moutan Cortex Radicis herbal-acupuncture at GB34 has therapeutic effects on hyperlipidemia and related complications in rats with high fat diet.

  • The paeonol content in roasted Moutan Cortex was increased about three times compared to that of untreated one. The paeonol content reached at its maximum level $(454.3\;{\mu}g/mg\;ethanol\;extract)$ after roasting at $190^{\circ}C$ for 30 minutes. Roasting processing did not affect on the DPPH radical scavenging activity of Moutan extracts.

  • From the fresh unripe fruits of Paeonia moutan Sim. (Paeoniaceae), paeoniflorin and its acyl congeners, benzoylpaeoniflorin and benzoyloxypaeoniflorin, along with ${\beta}-sitosterol$ and methyl gallate were isolated. All compounds were identified on the basis of spectral data and chemical reactions. However, paeonol was not detected from this plant parts. These results suggested that the chemical components of the unripe fruits were virtually similar to those of root barks.
