In order to develop anti-wrinkle agent, we measured the anti-oxidative activity of gallic acid (GA) from Paeonia suffruticosa Andrews and investigated its cytotoxicity in HaCaT cells and then investigated its effect on tumor necrosis factor alpha (TNF-${\alpha}$)-induced matrix metalloproteinase-1 (MMP-1) mRNA, protein expressions and secretion in same cells. GA showed anti-oxidative activity with $IC_{50}$ of 30 ${\mu}g/mL$ and its activity was higher than that of butylated hydroxyanisol (BHA). GA showed weak cytotoxicity with high concentration (200 ${\mu}g/mL$) in HaCaT cells. MMP-1 mRNA, protein expression and secretion induced by tumor necrosis factor alpha (TNF-${\alpha}$) in HaCaT cells were significantly decreased by treatment of GA with dose-dependent manner(p<0.05). Therefore, our findings suggest that GA can be useful as an active ingredient for cosmeceuticals of anti-wrinkle effects.

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.

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.

Objective : Skin aging is commonly observed in patients with diabetes mellitus, which can be accessed by the amount of skin collagen and matrix metalloproteinase-1 (MMP-1). In the present study, anti-skin-aging effects of Root Cortex of Paeonia Suffruticosa Andrews (PSA), which has been widely used to treat diabetes mellitus, are investigated. Methods : Streptozotocin (STZ) was intraperitoneally injected to rats to induce diabetes. Body weights, feed intake, organ weights, blood glucose, and other biochemical index are determined in both normal and diabetic rats. In order to study the effect of PSA on skin aging, the amount of skin collagen was measured in diabetic rats after PSA treatments. Also, MMP-1 synthesis in UVB-irradiated human skin fibroblasts was investigated. Results : 1. When PSA was administered to STZ-induced diabetic rats, feed intake was significantly increased and blood glucose and total cholesterol were decreased in a dose-dependent manner. However, there are no differences in individual organ weights, GOT, and GPT. 2. A decrease of skin collagen in diabetic rats was significantly suppressed when PSA was treated. 3. PSA also inhibited MMP-1 synthesis in UVB-irradiated normal human skin fibroblasts, similar to retinoid, a well-known effective anti-skin-aging substance. Conclusion: PSA suppressed a collagen decrease in diabetic rats and inhibited MMP-1 synthesis in UVB-irradiated human skin fibroblasts. Therefore, the treatment of PSA is very effective to slow down the skin aging process.

Now many sustitution and false articles is used in korea instead of mudanpi. To use mudanpi correctly, we will make a quilitative certificational plan of mudanpi to investigate all of lieraturea, records and documents. And we could reach conclusions as folloews. 1. Source Source of mudanpi is cortex of Paeonia suffruticosa Andrews(Family:Ranunculaceae) in korea and china. It needs an attention to distinguish into because there is a substitute and a rank in china. 2. process We have to work before harvesting fresh roots is dry perfectly. If outer skin dried moisture a little, cut off outer skin vertically at sunny day, remove a heart and sever, immedietly dry. When working, we have to take care of because of easy discoloration with moisture. 3. Quality (1) Functional standards A diameter is large, it do not exist a heart of wood, a bark is thick and powdery. Section surface is light white color and rich odor with many light crystals. (2) Physicochemical stamdards We think that it needs to raise a contant of paeonol at all kinds of testing standards. A contant of paeonol is at least more than 2.5%. A part of wood indicate a heart of wood which has no medical effects, but is a relatively heavy part. So a standart of wood must be lowered sifnificantly less than 1.0%. It must be content of ash is less than 6.0%, Content of acid-nonsoluble ash is less than 1.0%. A fixed quantity of paeonol is more than 2.5%. Contens of heavy metal has to detect less than 30 ppm and there is no reminding agriculural medince.

Objective : Daehwangmokdanpi-Tang (DWT) has been frequently used as a remedy for antiinflamation. To evaluate effect of acute pancreatitis by DWT, we examined the effects of DWT on the cholecystokinin-octapeptide (CCK)-induced acute pancreatitis (AP) in rats. Methods : Male Wistar rats weighing 200 to 250 g were divided into three groups. Normal untreated group, in treatment with DWT group; DWT was administered orally, followed by $75\;{\mu}g/kg$ CCK subcutaneously three times, after 1, 3 and 5 h. This whole procedure was repeated for 5 days. In treatment with saline group, the protocol was the same as in treatment group with DWT. Results : The author determined the pancreatic weight/body weight ratio, the levels of pancreatic HSP (heat shock protein)60 and HSP72 and the secretion of pro-inflammatory cytokines. Repeated CCK treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. DWT was significantly decreased the pancreatic weight/body weight ratio in CCK-induced AP. Futhermore, The author demonstrated that DWT increased HSP60 and HSP72 compared with CCK-induced AP. Additionally, the secretion of $IL-1{\beta}\;and\;TNF-{\alpha}$ and the levels of amylase and lipase were lower than that saline. Conclusions : These results suggested that DWT may has a protective effect against CCK-induced AP.
