  • Objectives : The purpose of the study is to test the antibacterial, anti-inflammatory and antioxidant effects of BPH, which is composed of Pini Densiflorae Nodi Lignum and Querci Acutissimae Fructus, Angelicae Gigantis Radix, Cnidii Rhizoma, Angelicae Dahuricae Radix, Angelicae Tenuissimae Radix. Method : Antibacterial and anti-inflammatory effects of BPH on Propionibacterium acnes, one of anaerobic bacteria species were evaluated by measuring the levels of 2,2-diphenyl-1-picrylhydrazyl (DPPH) elimination and lipid peroxidation. Result : When BPH was applied to CCD-986sk (Human normal fibroblast) to confirm the level of cytokine(tumor necrosis factor-alpha, interleukin-8), its level increased in proportion to that of BPH's concentration, which indicated dose-dependent relationship. Using the Disk diffusion to measure the bacterial growth inhibition zone varying BPH concentration, it was found that the antibacterial effect of BPH was less than that of erythromycin, the control group, but was higher than that of saline, and it increased with higher concentrations. In a liquid culture medium containing BPH, the growth rate of Propionibacterium acnes was decreased by more than 10% at 25% BPH. After adding P. acnes to THP-1 monocyte, and treated it with BPH, and measuring the concentration of TNF-a and IL-8, it was observed that the amount of TNF-alpha and IL-8 significantly decreased depending on the level of BPH concentration. The ability to eliminate DPPH increased with higher BPH concentration. The inhibition of lipid peroxidation was increased by BHT treatment in a dose-dependent manner. Conclusion : Using Propionibacterium acnes, an anaerobic bacteria, we confirmed that BPH has antibacterial, anti-inflammatory and antioxidant effects.

  • The effect on the antioxidant activity and Nitric Oxide activity production inhibitory activity of Taraxacum has not been known. Therefore, phenolics and flavonoid contents were investigated from the ethanol extracts of five different Taraxacum species. The results showed that, among the five Taraxacum, T. hallaisanensis contains the highest total phenolic and flavonoid contents. When the antioxidant activity was measured by DPPH, $ABTS^+$ and reducing power activity, the free radical scavenging activity of T. hallaisanensis was also the highest among five Taraxacum species. However, measurement by CCK-8 assay in Raw264.7 cells indicated that the extracts of Taraxacum species have no effect on cell viability. Moreover, we also investigated the effect of Taraxacum species on NO scavenging activity in lipopolysaccharide (LPS)-stimulated Raw264.7 cells. The results clearly showed that Taraxacum species inhibited NO production, and the inhibitory effect of T. hallaisanensis was the strongest. The above results suggested that Taraxacum species affected the antioxidant and NO scavenging activity, and among the five species, antioxidant and NO scavenging activity assay of T. hallaisanensis was significantly higher than those of other four Taraxacum species. Therefore, T. hallaisanensis could be used as a potential drug with anti-oxidant and anti-inflammatory effect.

  • Objectives: The object of this study was to observe the protective effect of Gamijipaesan aqueous extracts(GJS), which has been traditionally used in Korean medicine in obstetrics & gynecological fields as anti-infectious and anti-inflammatory agents, against mastitis induced by Staphylococcus aureus infection in a rat model through antibacterial, antiinflammatory, immunomodulatory, and anti-oxidant effects. Methods: Antibacterial activities of GJS against S. aureus were detected using standard agar microdilution methods, with the effects on the bacterial invasion and intracellular killing of individual test materials in human mammary gland carcinoma cell(MCF-7) and murine macrophages(Raw 264.7) at MIC1/2, MIC and MIC2 concentration levels. In addition, the effects on the cell viability, nitric oxide(NO), tumor necrosis factor(TNF)-${\alpha}$ and interleukin (IL)-6 productions of LPS activated Raw 264.7 cells. The changes on the mammary tissue viable bacterial numbers, myeloperoxidae(MPO), inducible nitric oxide synthetase(iNOS), TNF-${\alpha}$ and IL-6 contents were observed in the S. aureus in vivo intramammary infectious rat model. The anti-bacterial and anti-inflammatory effects were compared with ciprofloxacin and piroxicam, respectively in the present study. Results: MIC of GJS and ciprofloxacin against S. aureus were detected as $0.860{\pm}0.428$ (0.391-1.563) mg/ml and $0.371{\pm}0.262$(0.098-0.782) ${\mu}g/ml$, respectively. In addition, GJS and ciprofloxacin were also showed marked dosage-dependent inhibition of the both bacterial invasion and intracellular killing assays using MCF-7 and Raw 264.7 cells at MIC1/2, MIC and $MIC{\times}2$ concentrations, respectively. $ED_{50}$ against LPS-induced cell viabilities and NO, TNF-${\alpha}$ and IL-6 releases of GJS were detected as 0.72, 0.04, 0.08 and 0.11 mg/ml, and as 19.04, 4.18, 5.37 and 4.27 ${\mu}g/ml$ in piroxicam, respectively. 250 and 500 mg/kg of GJS also inhibit the intramammary bacterial growth, MPO, iNOS, TNF-${\alpha}$ and IL-6 contents in S. aureus in vivo intramammary infected rats, respectively. GJS 500 mg/kg showed quite similar antibacterial and anti-infectious effects as compared with ciprofloxacin 40 mg/kg and also showed similar anti-inflammatory effects as piroxicam 10 mg/kg, in S. aureus in vivo intramammary infectious models. Conclusions: The results obtained in this study suggest that over 250 mg/kg of GJS showed favorable anti-infectious effects against S. aureus infection in a rat model through their antibacterial, anti-inflammatory, immunomodulatory and anti-oxidant effects and therefore expected that GJS can be used as alternative therapies, having both anti-inflammatory and anti-infectious activities. However, more detail mechanism studies should be conducted in future with the efficacy tests of individual herbal composition of GJS and the screening of the biological active compounds in individual herbs. In the present study, GJS 500 mg/kg showed quite similar anti-infectious effects were detected as compared with ciprofloxacin 40 mg/kg treated rats, and also GJS shows quite similar anti-inflammatory effects as compared with piroxicam 10 mg/kg in S. aureus in vivo intramammary infectious rats, but ciprofloxacin did not showed any anti-inflammatory effects, and piroxicam did not showed anti-infectious effects in this study.

  • Cyanidin-$3{\beta}$-D-glycoside (C3G), which is widely distributed in herbal medicines and functional foods, exhibits anti-inflammatory, anti-oxidant, and anti-scratching behavioral effects. Orally administered C3G is metabolized to protocatechuic acid (PA) by gut microbiota. Therefore, we compared the anti-colitic effect of C3G to that of PA in mice with 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis. Orally administered C3G and PA preventively and curatively ameliorated TNBS-induced colitis parameters, including macroscopic colitis score, colon shortening, and increase of myeloperoxidase activity. Treatment with C3G or PA also inhibited the expression of cyclooxygenase-2, inducible NO synthatase, $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ and the activation of $NF-{\kappa}B$ in the colon of mice with TNBS-induced colitis. Furthermore, these also inhibited lipopolysaccharide-induced $NF-{\kappa}B$ activation and $TNF-{\alpha}$ expression in peritoneal macrophages. The anti-colitic effect of PA was more effective than C3G. Orally administered PA more potently attenuate colitis than C3G by inhibiting $NF-{\kappa}B$ activation and the anti-colitic efficacy of C3G may be dependent on the biotransformation of C3G to PA by gut microbiota.

  • This study was performed to investigate total phenolic contents, anti-oxidant, biological disease-related enzyme inhibitory, and anti-microbial effects of extracts of Lonicera morrowii leaves prepared with water and 40% ethanol. Anti-oxidative activities of the extracts increased in a dose-dependent manner and were very high even at low phenolic concentration. At phenolic concentrations ranging between 50 and 200 ㎍/mL, the water and ethanol extracts inhibited 39.34-76.35 and 47.53-99.83% of xanthine oxidase activity, 30.21-79.06, and 59.40-87.14% of angiotensin converting enzyme activity, and 59.81-80.35 and 36.06-63.58% of α-glucosidase activity, respectively. All inhibitory effect were increased in a dose-dependent manner. In the paper disc agar diffusion assay against seven microbes, L. morrowii extracts had anti-bacteria activities against Helicobacter pylori, Propionibacterium acne but no effect against other bacteria. These results indicate that the extracts from L. morrowii leaves have the possibility to be developed as a physiologically functional source for prevention of adult diseases.

  • Objectives : Parkinson's disease (PD) is a neurodegenerative disease caused by dopaminergic neuronal death in the substantia nigra pars compacta. PD is known to be linked with mitochondrial dysfunction and increased oxidative stress. In this study, anti-cytotoxic and anti-oxidative effect of 12 herbal formulae were compared. Methods : According to experts' advice, 12 types of herbal formulae (Gamisoyosan, Galgeuntang, Galgeunhaegitang, Banhabaekchoolcheonmatang, Bojungikgitang, Boheotang, Sihogyejitang, Sihosogantang, Sihocheonggantang, Ojeoksan, Cheongsanggyeontongtang and Palmultang) were selected from 56 types of herbal formulae covered by the National Health Insurance Service in Korea. To detect anti-oxidative effect, 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay was performed, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed to detect anti-cytotoxic effect of 12 herbal formulae using SH-SY5Y human neuroblastoma cells. Results : In DPPH assay, anti-oxidant activity was increased in a dose-dependent manner and half maximal inhibitory concentration was highest in the order of Galgeuntang, Gamisoyosan, Galgeunhaegitang, Ojeoksan, Palmultang, Sihogyejitang, Sihosogantang, Cheongsanggyeontongtang, Sihocheonggantang, Bojungikgitang, Boheotang and Banhabaekchoolcheonmatang. In MTT assay, concentration of 80% cell survival was highest in the order of Sihosogantang, Cheongsanggyeontongtang, Sihocheonggantang, Sihogyejitang, Bojungikgitang, Galgeuntang, Ojeoksan, Boheotang, Palmultang, Galgeunhaegitang, Banhabaekchoolcheonmatang and Gamisoyosan. Formulae with more than 50% DPPH radical scavenging activity at concentrations for 80% cell survival were Sihosogantang, Cheongsanggyeontongtang, Sihogyejitang, Galgeuntang and Sihocheonggantang. Conclusions : Sihosogantang, Cheongsanggyeontongtang, Sihogyejitang, Galgeuntang and Sihocheonggantang extracts can be candidate medicines for PD, but the effect should be validated in PD models.

  • Metabolic syndrome (MS) refers to a clustering of at least three of the following medical conditions: high blood pressure, abdominal obesity, hyperglycemia, low high-density lipoprotein level, and high serum triglycerides. MS is related to a wide range of diseases which includes obesity, diabetes, insulin resistance, cardiovascular disease, dyslipidemia, or non-alcoholic fatty liver disease. There remains an ongoing need for improved treatment strategies for MS. The most important risk factors are dietary pattern, genetics, old age, lack of exercise, disrupted biology, medication usage, and excessive alcohol consumption, but pathophysiology of MS has not been completely identified. Korean Red Ginseng (KRG) refers to steamed/dried ginseng, traditionally associated with beneficial effects such as anti-inflammation, anti-fatigue, anti-obesity, anti-oxidant, and anti-cancer effects. KRG has been often used in traditional medicine to treat multiple metabolic conditions. This paper summarizes the effects of KRG in MS and related diseases such as obesity, cardiovascular disease, insulin resistance, diabetes, dyslipidemia, or non-alcoholic fatty liver disease based on experimental research and clinical studies.

  • The antioxidant properties of mushroom and sea tangle extracts and mustard leaf added to Kimchi were investigated by total phenolic content, DPPH radical scavenging, ABTS anion scavenging, FRAP reducing power, and ORAC value. Total phenolic content of functional Kimchi (FK) was significantly higher than that of control Kimchi (CK). DPPH radical and ABTS anion scavenging activities of functional Kimchi were significantly higher than those of control Kimchi by 2.7 and 1.7 fold, respectively (p<0.05). Also, the FRAP reducing power and ORAC value of functional Kimchi increased compared to those of the control Kimchi by 1.6 and 1.1 fold, respectively (p<0.05). Our results suggest that functional Kimchi made by mushroom and sea tangle extracts and mustard leaf may be a potent antioxidant source and could be developed as a antioxidant functional food that may be for the effective treatment of oxidant conditions. Through continuous research and development of functional Kimchi by the use of mushroom and sea tangle extracts, it will be necessary to try to identify other functions that could be useful for preventing various diseases.

  • The antiproliferative effect of the water extract of the branch and root bark of Ulmi Pumilae Cortex(WEUPC) was investigated on the p53-negative human leukemia cell line (HL-60). A dose- and time-dependent inhibition of cell growth was observed; this effect appears to be due to induction of apoptosis. Involvement of oxidative stress is indicated by a dose-dependent increase in intracellular reactive oxygen species levels. In addition. anti-apoptic effect was observed in the cells simultaneously treated with WEUPC and the anti-oxidant N-acetylcysteine. WEUPC did not affect the anti-apoptotic Bcl-2 and the pro-apoptotic Bax, whereas p21/sup WAF1/CIPl/ was enhanced in a dose- and time-dependent fashion; this effect was partially inhibited by N-acetylcysteine. The increase in p21/sup WAF1/CIPl/ was accompanied by a parallel accumulation of cells in the G1 phase of the cycle. These results suggest that the p53-independent induction of p21/sup WAF1/CIP/ and the induction of apoptosis may mediate the anti proliferative effect of WEUPC at least in this study; on the basis of this observation, WEUPC could be proposed as an useful adjunct to the treatment of p53-deficient tumors, which are often refractory to standard chemotherapy.

  • Carcinogenesis can be theoretically divided to intiation step and promotion step. Intiation associates with genetic alterations including p53 tumor suppressor gene and ras oncogene. Promotion involves in clonal expansion of of an initiated cell by epigenetic mechanism, mainly through signal transduction and gene expression. Ultraviolet light (UV) acts as both initiator and promoter. Initiation is closely related with DNA damage induced by UV, including cyclobutane pyrimidine dimers, (6-4) photoproducts and 8-hydroxy-2'-deoxyguanosine. Cyclobutane pyrimidine dimers and (6-4) photoproducts are directly induced by UV, while 8-hydroxy-2'-deoxyguanosine is induced indirectly by the reactive oxygen species. Because initiation is an irreversal genetic event, while promotion is a reversal and epigenetic event, to know the molecular mechanisms of tumor promotion in UV-carcinogenesis is crucial to develop preventive medicine and suppress UV-carcinogenesis. Because ROS is also involved in signal transduction of the cell, anti-oxidant could be the good candidate of anti-promoting agent. Here, we describe the suppressive effect of UV-carcinogenesis by various anti-oxidant including olive oil. In addition, we discuss about the mechanism of UVB-induced expression of cyclooxygenase-2, which might be a representative molecule involved in promotion of UV-carcinogenesis.
