Medicinal plants with synergistic effects on growth inhibition of canter cells under oxidative stress were screened in this study. Methanol extracts from 51 natural medicinal plants which were reported to have anticancer effort on hepatoma stomach cancer or colon cancers which are frequently found in Korean, were prepared and screened for their synergistic activity on growth inhibition of cancer cells under chemically-induced oxidative stress by using MTT assay. Twenty seven samples showed synergistic activity on the growth inhibition in various extent under chemically-induced oxidative stress. Among those samples, eleven samples such as Melia azedarach, Agastache rugosa, Catalpa ovata, Prunus persica, Sinomenium acutum Pulsatilla koreana, Oldenlandia diffusa, Anthriscus sylvestris, Schizandra chinensis, Gieditsia sinensis, Cridium officinale, showed decrease in $IC_{50}$ values more than 50%, other 16 samples showed decrease in $IC_{50}$ values between 50-25%, compared with the value acquired when medicinal plant sample was used alone. Among those 11 samples, extract of Catalpa ovata showed the highest activity. $IC_{50}$ values were decrease to 61% and 28% when carcinoma cells were treated with Catalpa ovata extract in combination of 75 and 100 uM of hydrogen peroxide, respectively.

Ethanol extracts of the whole herb of Agastachis Herba (A) and of Pueraria Radix (P) alone and of their mixture (A+P) downregulated the cell growth, cyclooxygenase-2 (COX-2) expression, prostaglandin $E_2\;(PGE_2)$, and cGMP production. A, P, and A + P inhibited the cell growth of HT-29 colon cancer cells in a concentration- and time-dependent manner but not the growth of normal colon cell, CCD-112CoN. In addition, they markedly inhibited the productions of $PGE_2$ and cGMP as well as the mRNA expression of COX-2. These data suggest that non-toxic concentration of A, P, and A + P have a significant effect on the in vitro growth of HT-29 cells, specifically through the inhibition of the $PGE_2$ production via COX-2.

The pharmacological rationale of Agastache rugosa (AR) or Pogostemon cablin (PC), which have been used in traditional Korean medicine to treat dampness pattern or syndrome in gastrointestinal tract, was investigated on the gastrointestinal disorders. In-vivo model studies that examined the effect on the gastrointestinal disorders of AR or PC were collected. They were classified into disease-induced in-vivo models or non-disease in vivo models. The target disease, animal species, induction method, administration, and outcomes (changes in morphological and histological parameter, or blood and fluid) of each study were analyzed. The therapeutic mechanism of AR or PC extract was evaluated by the induced diseases and the changes in outcomes. There were contradictory reports on gastrointestinal motility of AR or PC in disease non-disease in-vivo model. AR or PC inhibited gastrointestinal motility in disease model of increased gastrointestinal motility, while promoted motility in disease model of decreased gastrointestinal motility. AR or PC also inhibited inflammatory changes in gastrointestinal inflammation model. These results suggest that the bidirectional regulation of gastrointestinal motility and the improvement of gastrointestinal inflammatory disorders might underpin traditional therapeutic effect of AR or PC, that is effect to resolve dampness of gastrointestinal tract.

Objectives: This study was performed to investigate the effects of two herbal medicines, Agastachis Herba and Lysimachiae Herba, on a cellular model of non-alcoholic fatty liver diseases (NFLDs). Methods: HepG2 cells were treated with palmitic acid and with various concentrations of Agastachis Herba (AH) or Lysimachiae Herba (LH) extract in water. The lipotoxicity was assessed using EZ-cytox, and the lipoapoptosis was assessed using cell death detection ELISA. Intracellular lipids were measured by oil red O staining. The efficacy of AH and LH on sterol regulatory element-binding transcription factor-1c (SREBP-1c), fatty acid synthase (FAS), and acetyl-CoA carboxylase (ACC) in HepG2 cells was measured by reverse transcription polymerase chain reaction (RT-PCR). Results: Both AH and LH extracts increased lipoapoptosis and decreased lipotoxicity and levels of SREBP-1c, ACC, and FAS (SREBP-1c, ACC, and FAS are factors in lipid synthesis). In the oil red O staining experiment, both extracts also reduced intracellular lipid accumulation; in this instance, LH's efficacy was superior to that of AH. Conclusions: According to the results, both AH and LH are likely to contribute to non-alcoholic fatty liver disease, as both interfere with lipid synthesis.

Developing a menu for foodservice operations utilizing a Yaksun meets with the desire of customers who have keen interest in health food. In addition, it is possible to expect the additional advantage of decreasing hygiene risk, which can be caused by large quantity cooking, by the efficacy of medicinal herbs used in Yaksun. Accordingly, this study provides with basic information for the development of a Yaksun menu for foodservice operations utilizing Gwackhyang by evaluating the sensory quality and microbiological quality of bean soup added of Gwackhyang. The standard plate counting significantly decreased as the addition quantity of Gwackhyang increased (p<0.001). All bean soups, which were kept at room temperature and refrigerator for 3 hours after cooking, met the safety standard 5.00 CFU/g. The number of coliforms also significantly decreased as the addition quantity of Gwackhyang increased. The bean soups in control group exceeded the safety standard of 2.00 CFU/g after 1 hour at room temperature and in refrigerator. On the other hand, all Gwackhyang bean soups met safety standard, only excluding G1 with 1% Gwackhyang kept at room temperature. Accordingly, it has been confirmed that the addition of Gwackhyang during bean soup production decreases the microorganism level of bean soup. Both standard plate counting and the number of coliforms significantly increased after 3 days in refrigerator; however, the increasing extent of Gwackhyang bean soups were less than the control group bean soups. The control group received scored highest in 3 sensory characteristics out of 5 sensory characteristics. However, G1 with 1% Gwackhyang also scored highest in 2 sensory characteristics, which were taste and overall preference. G2 also scored 4.45 in color and 4.15 in fragrance, which were lower than the control group but were above average.

Objectives : In this study, we investigated the effects of Agastachis Herba water (AH-W) extract on compound 48/80-induced mast cell degranulation and histamine release in human mast cells and also anti-asthmatic effect of AH-W extract on ovalbumin (OVA)-induced asthma in mice. Methods : Human mast cells, HMC-1 were treated with AH-W extract in the presence or absence of compound 48/80 (C48/80). Mast cell degranulation was observed by microscope, and the histamine release was measured in culture medium by ELISA. For preparation of asthmatic in vivo model, mice were sensitized (0, 7, and 14 days) with OVA and airway challenged (21, 23, 25, 27, and 29 days). AH-W extract at doses of 100 and 300 mg/kg/body weight was orally administered during OVA challenge once per a day. The levels of immunoglobulin (Ig) E, and Th1/Th2 cytokines, IFN-$\gamma$ and IL-4 were measured in the sera of mice by ELISA. The histopathological change of lung tissues was observed by hematoxylin and eosin (H&E) and Periodic Acid Schiff (PAS) staining. Results : The treatment of AH-W extract significantly decreased the mast cell degranulation and histamine release in C48/80-stimulated HMC-1 cells. In addition, The administration of AH-W extract at does of 100 and 300 mg/kg significantly decreased the serum levels of OVA-specific IgE compared with those of OVA control group. In H&E and PAS staining, AH-W extract inhibited OVA-induced airway inflammation, and inflammatory cells infiltration, and also histopathological damages on lung tissues such as bronchiole epithelial desquamation, goblet cells hyperplasia, and mucin releasing. Conclusions : These results indicate that AH-W extract may improve asthmatic symptoms through mast cell stabilization and inhibiting the lung inflammation in bronchial asthma.

Bone is continuously remodeled by osteoblasts and osteoclasts. We investigated the effects of medicinal herbs, which act on bone metabolism. Fifteen kinds of medicinal herb extracts were screened for bone formation activity with osteoblastic cells, and MC3T3-E1 and bone resorption were screened with osteoclasts derived from mouse bone marrow macrophages. Among these samples, Actinidia polygama, Eucommia ulmoides Oliv., Schizonepeta tenuifolia, Sorbus commixta, and Zingiber officinale Rosc. extracts showed strong bone-forming activity accompanied with osteoblast proliferation and alkaline phosphatase activity. In addition, these extracts decreased tartrate-resistant acid phosphatase activity against osteoclast differentiation. The results indicate that these medicinal herb extracts can potentially prevent bone-related diseases such as osteoporosis by increasing osteoblast differentiation and reducing osteoclast activity.

Objectives: The herb of Agastache rugosa (AR) is a traditional herbal medicine used for colds, vomiting and furuncles. However, there are few reports to investigate the inhibitory effects of AR on obesity. In this study, the effects of AR on high fat diet (HFD)-induced obesity and its mechanism of actions were investigated in experimental animals. Methods: The mice were fed HFD for 4 weeks to induce obesity. After randomly divided into normal fat diet, HFD and AR groups, 200 mg/kg of AR was administrated for 4 weeks with continuous HFD feeding while vehicle was orally treated to HFD group. Food intake and body weight were recorded weekly. Results: Increased body weight by HFD was improved by AR treatment. AR administration inhibited an increase of visceral fat weight as well as adipocyte hypertrophy. Hepatic steatosis was ameliorated in AR-treated mice. In addition, treatment of AR attenuated the expression of adipogenic transcription factor, peroxisome proliferator-activated receptor (PPAR)-gamma in the epididymal adipose tissue. Also the increased serum leptin level by HFD was maintained in AR group, leading to inhibition of food intake. Conclusions: AR treatment showed inhibitory effects on HFD-induced obesity by inhibition of PPAR-gamma and reduction of food intake. AR could be an alternative treatment for obesity.
