Objectives : The purpose of this study is to examine the effects of antioxidant activities and serotonin activities of OnDam-tang-Kami-bang (ODK) on P815 Mast Cell. Methods : The effects of ODK on the activation of DPPH radical-scavenging and SOD in P815 mast cell were investigated. The effect of ODK on the content of serotonin in P815 mast cell was investigated. The effects of ODK on the activation of 5-HTT, TPH-1 mRNA in P815 mast cell were investigated. Results : It was found that the ODK increased SOD activities and DPPH radical-scavenging activities in the P815 mast cell. Also, the ODK decreased the intracellular concentration of serotonin in the P815 mast cell. Further, the ODK decreased 5-HTT and TPH-1 mRNA expression in the P815 mast cell. Conclusions : The results of this experiment reveal that ODK has significant antioxidative effects. However, ODK decreased the intracellular concentration of serotonin and mRNA expression of 5-HTT and TPH-1, which implies that ODK might not be effective for treating depression. Further research exploring the positive aspects of ODK is suggested such that ODK could adequately target symptoms that are to be treated.
'Angelica' is one of the most traditionally consumed medicinal herbs around Northeast Asia including Korea for treatments of various diseases or health care purposes like hematopoiesis, blood circulation for women, sedative, analgesic, and a tonic medicine etc. Angelica gigas Nakai, a Korean native species of Angelica, is clearly different from the others in containing a high concentration of active ingredients like pyranocoumarines including decursin, decursinol, and decursinol angelate. These compounds have various kinds of positive effects such as anti-tumor activity including the precaution of neutropenia occurred during anticancer drug administration, improvements of metabolic disorders, menstrual irregularity, impairment of renal function, respiration improvement, cognition-enhancement, anti-inflammatory effect, anti-oxidative effect, enhancing fertility and so forth. Thus it implies incredible potentialities in future development for foods and drugs. However, certain purity-related qualities and/or overdose in food products can cause side effects like toxicities; therefore, their safety profiles should also be considered. This review focuses on the positive and negative effects of three pyranocoumarines in Angelica gigas Nakai and some possibilities and considerations for future food and drug products development.
This study was conducted in order to compare the biological activities of water extracts and sugar immersion extracts of green pepper (Capsicum annuum L.), purslane (Portulaca oleracea L.) and shiitake (Lentinula edodes (Berk.) Pegler) by measuring total polyphenol and flavonoid contents, antioxidant activities and inhibitory effects on ${\alpha}$-amylase and ${\alpha}$-glucosidase. The contents of total polyphenols and flavonoids were higher in water extracts than in sugar immersion extracts. The anti-oxidative activities of water and sugar immersion extracts were measured using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging activity assay and reducing power assay. All extracts scavenged radicals in a concentration-dependent manner, and water extracts showed stronger radical scavenging activity and reducing power than sugar immersion extract. However, they all exhibited lower activities than ascorbic acid. Compared to the anti-diabetic drug acarbose, which was used as a positive control, the two types of extracts exhibited low ${\alpha}$-glucosidase inhibitory activities, although the activity of sugar immersion extracts were 2-fold higher than that of water extracts. ${\alpha}$-Amylase inhibitory action was not observed for any of the extracts. Finally, by cytotoxicity test, we confirmed that sugar immersion extracts were safer than water extracts. These results indicate that water extracts and sugar immersion extracts of green pepper, purslane and shiitake have different advantages in terms of their antioxidant and anti-diabetic effects, respectively.

To determine the kimchi with the best quality and functional characteristics, we manufactured and compared recipes for Korean and Japanese kimchi made either Korean or Japanese baechu cabbages. All batches were fermented for 4 weeks at $5^{\circ}C$, and tested for pH, texture, microbial count, sensory evaluation, DPPH radical-scavenging activity, and cell proliferation (using the MTT assay on AGS human gastric cancer cells). By the third week of fermentation, Korean kimchi made with Korean baechu (KK) and Japanese kimchi made with Korean baechu (KJ) showed a higher acidity than Korean or Japanese kimchi made with Japanese baechu (JK and JJ, respectively). KK ranked highest in springiness, followed by KJ, JK, and JJ. Therefore, the texture of kimchi produced with Korean baechu was appears better than kimchi produced with Japanese baechu. This was confirmed in masticatory tests. Kimchi produced with Korean baechu (KK and KJ) showed lower total aerobic bacterial counts, while the total lactic acid bacterial counts were higher (p<0.05). In sensory evaluation test, KK received the highest overall acceptability score, while JJ earned the lowest score. In the DPPH assay for anti-oxidative activity, KK showed a 94% anti-oxidative effect, followed by KJ (92%), JK (91%), and JJ (88%) (p<0.05). In the MTT assay for analyzing the cell proliferation of AGS human gastric cancer cells, KK showed a 64% anticancer effect in vitro, followed by KJ (57%), JK (38%), and JJ (26%). Therefore, the anti-oxidative and anti-cancer functionalities of kimchi made with Korean baechu were higher than those made with Japanese baechu, regardless of the kimchi recipe applied. Overall, Korean baechu had important and superior effects on the quality and functionality of kimchi.
The renoprotective effects of Korean Red Ginseng were examined in STZ-induced diabetic spontaneously hypertensive rats (SHR). After 3 day administration of streptozotocin (STZ), animals were divided into four groups : Group 1, hypertensive rats (H); Group 2, hypertensive rats with diabetes (HD); Group 3, hypertensive rats with diabetes administered with 100 mg/kg of ginseng total saponin(GTS); Group 4, hypertensive rats with diabetes administered with 600 mg/kg of ginseng non-saponin (GNS). After 2 weeks oral administraions of GTS and GNS, body weight, kidney weight, plasma glucose, urinary albumin excretion, serum creatinine, urea nitrogen and blood pressure were examined. After 3,7 and 21 day of STZ administration, expressions of TGF-${\beta}$1 and fibronectin in kidney were analyzed by immunoblotting and/or immunohistochemistry. GTS and GNS treatments slightly decreased blood pressure when compared to H and HD groups. Also, GTS and GNS treatments ameliorated kidney hypertrophy without affecting plasma glucose levels. Meanwhile, GNS treatment increased Cu/Zn-SOD activity in kidney and generally showed more efficient renoprotective effects than GTS. We suggest that the renoprotective effects of ginseng partially result from downregulations of TGF-${\beta}$1, fibronectin expressions and anti-oxidative activity of ginseng non-saponin.
Black chokeberries (scientific name Aronia melanocarpa) have been reported to have major effects due to anti-oxidant, anti-inflammatory, and anti-cancer capabilities. In this study, we investigated the anti- wrinkle effects of A. melanocarpa, including collagenase inhibition effects and their molecular biological mechanisms, such as oxidative stress-induced matrix metalloproteinase (MMP), mitogen-activated protein (MAP) kinase, and activator protein (AP)-1 expression and/or phosphorylation. In collagenase inhibition activity, the ethyl acetate fraction of black chokeberry (AE) was 77.2% at a concentration of 500 μg/ml, which was a significant result compared to that of Epigallocatechin gallate (positive control, 83.9% in 500 μg/ml). In the reactive oxygen species (ROS) assay, the AE produced 78% of ROS in 10 μg/ml and 70% of ROS in 75 μg/ml, which was a much lower percentage than the ROS production of H2O2-induced CCRF S-180II cells. In the MTT assay, cell viability was increased dose-dependently with AE in H2O2-induced cells. In protein expression by western blot assay, the AE suppressed the expression and phosphorylation of MMPs (MMP-1, -3, -9), MAPK (ERK, JNK, and p38), and AP-1 (c-Fos and c-Jun), and expressed the pro-collagen type I in H2O2-induced cells. These results suggest that black chokeberries have anti-wrinkle and collagen-production effects, and they may be used in applications for material development in the functional food and cosmetic industries.
Bibimbab (mixed rice) is a traditional Korean one-dish meal. This study was carried out to investigate the anti-inflammatory and antioxidative effects of raw and seasoned ingredients used in Bibimbab (Cucurbita moschata P., Platycodon grandiflorum A., Vigna radiata L., Porphyra yezonensis udea, Allium ampeloprasum L., Pterdium aguilinum, Raphanus sativus). Human mast cells (HMC-1) were pretreated with 70% ethanol extracts of Bibimbab and further cultured for an appropriate time after the addition of phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. Cell viability was determined by an MTT assay. None of the ingredients showed cytotoxic effects at a concentration of 1.0 ${\mu}g/ml$. Anti-inflammatory effects were analyzed at 0.01, 0.1, and 1.0 mg/ml concentrations of the raw, seasoned ingredients of PMA. A23187 stimulated HMC-1. Among the various ingredients, seasoned A. ampeloprasum L. extract showed the highest inhibition of TNF-${\alpha}$ and IL-6 secretion (90% and 93%, respectively) at a concentration of 1.0 mg/ml. The R. sativus extract showed the highest inhibition (85%) of IL-8 secretion. DPPH analysis of the antioxidation properties of the ingredients showed that raw and seasoned A. ampeloprasum extracts exhibited the highest DPPH free radical scavenging activity (67.50 and 73.65%, respectively). These results suggest that seasoned ingredients used in Bibimbab have lower anti-inflammatory effects in relation to TNF-${\alpha}$ and IL-6 secretion than raw ingredients in PMA- and A23187-treated HMC-1. In addition, the seasoned ingredients showed a tendency to increase antioxidative activity. Therefore, the ingredients used in Bibimbab have potential as anti-inflammatory and antioxidation agents.

Saposhnikovia has been used as a traditional medicinal herb in Asia because of the reported anti-inflammatory, anti-allergic rhinitis, pro-whitening, anti-atopy, anti-allergy, and anti-dermatopathy effects of the phytochemical compounds it contains. In this study, we investigated the antioxidant effects of a Saposhnikovia extract after fermentation by Lactobacillus plantarum BHN-LAB 33. Saposhnikovia powder was inoculated with L. plantarum BHN-LAB 33 and fermented at $37^{\circ}C$ for 72 hr. After fermentation, the total polyphenol content of the Saposhnikovia extract increased by about 14%, and the total flavonoid content increased by about 9%. The superoxide dismutase-like activities, DPPH radical scavenging, ABTS radical scavenging, reducing power activity, and tyrosinase inhibition activity also increased after fermentation by approximately 70%, 80%, 45%, 39%, and 44%, respectively. The results confirmed that fermentation of a Saposhnikovia extract by L. plantarum BHN-LAB 33 is an effective way to increase the antioxidant effects of the extract. The bioconversion process investigated in this study may have the potential to produce phytochemical-enriched natural antioxidant agents with high added value from Saposhnikovia matrices. These results can also be applied to the development of improved foods and cosmetic materials.

Inflammatory response and oxidative stress play critical roles in the development and progression of many human diseases. Therefore, a great deal of attention has been focused on finding functional materials that can control inflammation and oxidative stress simultaneously. The purpose of this study was to investigate the effects of Socheongja and Socheong 2, Korean black seed coat soybean varieties, on the inflammatory and oxidative stress induced by lipopolysaccharide (LPS) in RAW 264.7 macrophages. Our data indicated that the extracts of Socheongja (SCJ) and Socheong 2 (SC2) significantly suppressed LPS-induced production of nitrite oxide (NO) and prostaglandin $E_2$, key pro-inflammatory mediators, by suppressing the expression of inducible NO synthase and cyclooxygenase-2. It was also found that SCJ and SC2 reduced the LPS-induced secretion of pro-inflammatory cytokines, such as tumor necrosis $factor-{\alpha}$ and $interleukin-1{\beta}$, which was concomitant with a decrease in the protein levels. In addition, SCJ and SC2 markedly diminished LPS-stimulated intracellular reactive oxygen species accumulation, and effectively enhanced nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase (HO)-1 expression. Furthermore, LPS-induced activation of mitogen-activated protein kinases (MAPKs) was abrogated by SCJ and SC2. Taken together, these data suggest that SCJ and SC2 may offer protective roles against LPS-induced inflammatory and oxidative responses in RAW 264.7 macrophages through attenuating MAPKs pathway, and these effects are mediated, at least in part, through activating Nrf2/HO-1 pathway. Given these results, we propose that SCJ and SC2 have therapeutic potential in the treatment of inflammatory and oxidative disorders caused by over-activation of macrophages.
BACKGROUND: Anthracnose disease caused by Collectotrichum spp. is one of the most important worldwide devastating diseases in red pepper plants. Fungicides using plant extracts have several advantages, compared to synthetic chemical fungicides, because they are naturally occurring compounds, are usually safe for agricultural environment and are used for producing highly valuable agricultural products. Efforts for seeking an anti-fungal activities using naturally occurring compounds were mostly conducted from medicinal plant extracts. Sap of Rhus verniciflus was known to have healing effects on several human diseases. Recently, the extracts of Rhus verniciflus were actively tested for anti-cancer, anti-oxidative, and anti-fungal effects. In this study, the extract of Rhus verniciflus was tested for anti-fungal activity against Colletotrichum spp., which cause anthracnose in red-pepper. METHODS AND RESULTS: After neutralizing extracts of Rhus verniciflus (urushiol contents 70%) with autoclave, the crude extracts were used to investigate inhibitory effects for mycelial growth and spore germination of Colletotrichum spp. on PDA media. The mycelial growth and spore germination of Colletotrichum spp. were inhibited 18-39% and over 50% in response to crude extract of R. verniciflus (1.0 mg/mL). After spraying the extracts at the same concentrations above and then artificially inoculating Colletotrichum spp. on blue and red-pepper fruits, in vitro inhibition effects were examined. At 1.0 mg/mL, the crude extract of R. verniciflus showed inhibition activity in anthracnose incidence on blue- and red-pepper as 68.1-75.0%, through a artificial inoculation of Colletotrichum spp. in a laboratory. For in vivo inhibitory effects, the extracts (1.0, 0.1, and 0.01 mg/mL) were treated on red-pepper plants grown in green house 3 times at the interval of 1 week. Then inhibitory effects were determined by counting diseased fruits at 1 week after final treatment. The incidence of anthracnose was inhibited over 60% in the greenhouse by treatment of crude extract of R. verniciflus (1.0 mg/mL). CONCLUSION(s): Extracts of Rhus verniciflus were shown to have inhibitory effects on mycelial growth, spore germination of Colletotrichum spp. in vitro and on occurrence of anthracnose on pepper fruit in green house.
