Diabetes mellitus is the fifth leading cause of death among Koreans. Control of hyperglycemia and dyslipidemia is strongly correlated with decrease in risks for cardiovascular diseases, the most common and fatal diabetic complication. The effects of chronic feeding of a mixture of Chinese herbs on blood lipid profile were measured in an animal model of type 2 diabetes mellitus, db/db mice (C57BL/Ks). The Chinese herb mixture was composed of Panax ginseng C. A. Meyer,Astragalus membranaceus, Glycyrrhiza uralensis, Lycium chinense, Morus, Pueraria thunbergiana, Prunella vulgaris var. lilacina, Acanthopanax sessiliflorus, Schizandra chinensis, Scutellaria baicalensis, Dioscorea batatas, Polygonatum doratumvar. pluriflorum, Paeonia lactiflora, and Rehmannia glutinosa in a ratio of 1 : 0.7 : 0.4 : 0.7 :0.4 : 0.7 : 1.1 : 0.9 : 0.4 : 0.4 : 0.7 :0.7 : 0.9 : 0.9. Methanol extract of the Chinese herb mixture was tested for the inhibitory activity against yeast ${\alpha}$-glucosidase in vitro. The Chinese herb mixture extract inhibited ${\alpha}$-glucosidase by 25.2% at the concentration of 0.5mg/mL. Four weekold male db/db mice (n = 14) were fed AIN-93G semipurified diet or diet containing 10% powder of the Chinese herb mixture for 6 weeks after 1 week of adaptation period. Body weight (39.5 ${\pm}$ 1.6 g) and food intake (4.3 ${\pm}$ 0.6 g/day) of the Chinese herb group were not significantly different from those of the control group (40.4 ${\pm}$ 2.6 g and 4.5 ${\pm}$ 0.6 g/day). Consumption of Chinese herb mixture significantly decreased plasma glucose level (442.5 ${\pm}$ 36.0mg/dL) compared with the control group (489.8 ${\pm}$ 34.6 mg/dL, p < 0.05). Plasma cholesterol level (159.2 ${\pm}$ 18.4 mg/dL) of the Chinese herb group was significantly lower than that of the control group (185.4 ${\pm}$ 13.7 mg/dL, p < 0.05). Blood glycated hemoglobin (6.3 ${\pm}$ 0.8%) and plasma triglyceride levels (99.4 ${\pm}$ 15.0mg/dL) of the Chinese herb group were not significantly different from those of the control group (6.7 ${\pm}$ 0.7% and 108.8 ${\pm}$ 11.0mg/dL). Thus, the Chinese herb mixture could be useful in the treatment of diabetes and cardiovascular complications of diabetes.

Atopic dermatitis (AD) is a common skin disease characterized by chronic and relapsing inflammatory dermatitis with immunological disturbances. In spite of the continuous increase in the incidence of AD, it is regrettable that till date there is no effective treatment to treat the same. Therefore, the present study was designed to examine the possible anti-atopic effects of Castanea crenata inner shell extracts fermented by Lactobacillus bifermentans (FCS) in 2,4-dinitrochlorobenzene (DNCB) induced AD in NC/Nga mice. Based on the results of HPLC analysis, we found that FCS contains anti-inflammatory factors such as gallic acid (10.18 mg/g) and ellagic acid (2.14 mg/g). The groups that we have used in this study included 0.1%, 1%, 5% fermented Castanea crenata inner shell extracts (FCS 0.1, FCS 1, FCS 5), 1,3-butylene glycol treated control (AD), and normal mice. After topical FCS treatment, we observed that the clinical severity score for AD was lower in both the FCS 1 and FCS 5 groups than the AD group. We also proved beyond doubt that there was improvement of melanin, erythema and skin moisture indices in the FCS 5 group. Spleen index and gene expression levels of pro-inflammatory cytokines such as IL-$1{\beta}$ and TNF-${\alpha}$ were significantly decreased in the FCS 5 group compared to the AD group (P<0.05). Further, we also found that the level of serum immunoglobulin E (IgE) in the FCS-treated group was decreased in a concentration-dependent manner. The results of our study suggest that FCS can be effectively used as a cosmeceutical ingredient for both the prevention and improvement of AD.

The present study investigated the effect of physiologically active polysaccharide (SP1) isolated from Salicornia herbacea on streptozotocin-induced diabetic rats. Male Spraque-Dawley rats were divided into four groups which were normal control group (NC), diabetic control group (DC), diabetic CSP group (DCSP), and diabetic SP1 group (DSP1). Animals were administrated with 2% experimental drinks for 6 weeks. The levels of glucose, triglyceride, total cholesterol, and high density lipoprotein (HDL)-cholesterol in the serum were measured before and after intake of test compounds. The levels of glucose and triglyceride in the DSP1 were significantly lower than those in the DC by 25% and 20%, respectively. The levels of total cholesterol and high density lipoprotein (HDL)-cholesterol in the DSP1 were similar to those in the DC. These results suggest that SP1 substantially exhibit anti-hyperglycemic and anti-hypertriglyceridemic activity in diabetic rats. Therefore SP1 is believed to show remarkable anti-diabetic effect on streptozotocin-induced diabetic rats.

This study aimed to investigate the protective effect of dandelion water extract (DWE) on liver injury induced by D-galactosamine (GalN) in Sprague-Dawley rats. Fifty rats were divided into 5 groups; normal control (C), DWE-control (DWE-C: saline injection after feeding 3% DWE diet), GalN-control (GalN-C: GalN injection after normal diet), DWE I (GalN injection after feeding 1.5% DWE diet), and DWE II (GalN injection after feeding 3% DWE diet). After 2 weeks, the acute hepatitis was induced by GalN (650 mg/kg, i.p.) and 24 hrs later, all rats were sacrificed. The DWE supplement ameliorated the serum alanine and aspartate aminotransferase (AST, ALT) as well as alkaline phosphatase (ALP) and tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$. Hepatic antioxidative enzyme activities, such as catalase, GSH peroxidase, GSH reductase, and Mn-superoxide dismutase (SOD) were slightly or significantly elevated by the treatment of DWE. Moreover, the histological examination corresponded with these biochemical observations. According to these findings, dandelion could be used as a potential therapeutic material for treating chemically induced acute hepatitis.

Luteolin and chicoric acid are the most abundant phytochemicals in dandelion (Taraxacum officinale) leaf. In this study, four kinds of extraction methods [hot water, ambient temperature (AT) water, ethanol, and methanol] were applied to analyze the contents of both phytochemicals and verify their anti-inflammatory and antioxidative activities. The methanol extract showed the most potent nitric oxide (NO) inhibitory effect. The luteolin and chicoric acid concentrations were 3.42 and $12.86\;{\mu}g/g$ dandelion leaf in the methanol extract. The NO-suppressive effect of luteolin and chicoric acid was identified in a dose-dependent manner with $IC_{50}$ values of $21.2\;{\mu}M$ and $283.6\;{\mu}M$, respectively, in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells without cytotoxicity. Malondialdehyde (MDA) concentration, as an index for free radical injury on cell membrane, was also dose-dependently inhibited by the two compounds. The suppressive effect was further examined using mRNA and protein expression levels, which were attributable to the inhibition of inducible nitric oxide synthase (iNOS). These results suggest that two phytochemicals in dandelion leaf, luteolin and chicoric acid, may play an important role in the amelioration of LPS-induced oxidative stress and inflammation.

High performance liquid chromatography(HPLC) was used for the determination of eleutherosides B and E in various parts of Acanthopanax species. Eleutheroside B was detected in the stem (1.45 mg/g) and the root (0.59 mg/g) of A. senticosus and the stem (0.31 mg/g) of A. senticosus grafted on A. sessiliflorus. But there is no detection of eleutheroside B in A. sessiliflorus and the root of A. senticosus grafted on A. sessiliflorus. Eleutheroside E was detected in the stem (0.92, 0.97 and 0.30 mg/g, respectively) and the root (0.65, 0.94, 0.34 mg/g, respectively) of A. senticosus, A. sessiliflorus and A. senticosus grafted on A. sessiliflorus.

Cassumunar ginger (Zingiber montanum Roxb.) was grown in the experimental field at the Department of Horticulture, Kasetsart University, Thailand. The antioxidant activity and volatile oil content of rhizomes of varying age were measured. Antioxidant activity as determined using the DPPH (diphenyl-2-picrylhydrazyl) method differed significantly between samples of different ages. Antioxidant activity and rhizome age were positively correlated, with 22-month old rhizomes showing the highest radical scavenging activity (79.19%). Volatile oil was obtained by steam distillation of fresh rhizomes. The extraction yield of volatile oil was highest in l6-month old rhizomes (13.02 mL/kg). GC-FID data indicated the presence of three major compounds, sabinene, terpinen-4-ol and (E)-1-(3',4'-dimethylphenyl) butadiene (DMPBD), however none of the major components were correlated with the age of rhizome.
