We examined the anti-inflammatory effect of the peel extract of the newly bred Korean apple (Malus domestica Borkh.) cultivar Green ball. To test its possible use as anti-inflammatory functional material, Raw 264.7 macrophages were treated with pro-inflammatory lipopolysaccharide (LPS) in the presence or absence of Green ball apple peel ethanol extract (GBE). Notably, up to 500 μg/mL of GBE did not result in any signs of inhibition on cellular metabolic activity or cytotoxicity in Raw 264.7 macrophages. Supplementation with GBE to LPS-treated Raw 264.7 macrophage significantly suppressed various pro-inflammatory responses in a dose-dependent manner, including i) nitric oxide (NO) production, ii) accumulation of inducible NO synthase and cyclooxygenase-2, iii) phosphorylation of nuclear factor-kappa B (NF-κB) subunit p65, and iv) expression of pro-inflammatory biomarker genes, including tumor necrosis factor alpha, interleukin 1 beta, interleukin 6, monocyte chemoattractant protein-1, and prostaglandin E synthase 2.

Environmental pollution caused by various heavy metals is a serious global problem. To solve this problem, microbial bioremediation of contaminated metals has developed rapidly as an effective strategy when physical and chemical techniques are not suitable. In this study, cadmium (Cd)-tolerant soil bacteria were isolated via artificial induction in laboratory conditions instead of screening bacteria naturally adapted to metal-contaminated soils. Wild-type (WT) bacteria grown in uncontaminated soils were artificially and sequentially adapted to gradually increasing Cd concentrations of up to 15 mM. The resultant cells, named Soil-CdR15, survived at a Cd concentration of 10 mM, whereas WT cells failed to survive with 4 mM Cd on solid media for 2 d. In liquid media containing Cd, the Soil- CdR15 cells grew with 15 mM Cd for 7 d, whereas the WT cells could not grow with 5 mM Cd. Both Soil-CdR15 and WT cells removed approximately 35% of Cd at the same capacity from liquid media containing either 0.5 or 1.0 mM Cd over 2 d. In addition to Cd, the Soil-CdR15 cells showed increased resistance to nickel, zinc, and arsenic compared to WT cells. The Soil-CdR cells were identified as Burkholderia sp. by partial sequencing of 16S rRNA. The data presented in this study demonstrate that isolation of heavy metal-tolerant microorganisms via artificial induction in laboratory conditions is possible and may be useful for the application of the microorganisms for the bioremediation of heavy metals.

When blood vessels are damaged, a fast hemostatic response should occur to minimize blood loss and maintain normal circulation. Platelet activation and aggregation are essential in this process. However, excessive platelet aggregation or abnormal platelet aggregation may be the cause of cardiovascular diseases such as thrombosis, stroke, and atherosclerosis. Therefore, finding a substance capable of regulating platelet activation and suppressing agglutination reaction is important for the prevention and treatment of cardiovascular diseases. 6,7-Dimethoxy-2Hchromen- 2-one (Scoparone), found primarily in the roots of Artemisia or Scopolia plants, has been reported to have a pharmacological effect on immunosuppression and vasodilation, but studies of platelet aggregation and its mechanisms are still insufficient. This study confirmed the effect of scoparone on collagen-induced human platelet aggregation, TXA2 production, and major regulation of intracellular granule secretion (ATP and serotonin release). In addition, the effect of scoparone on the phosphorylation of the phosphoproteins PI3K/Akt and mitogenactivated protein kinases (MAPK) involved in signal transduction in platelet aggregation was studied. As a result, scoparone significantly inhibited the phosphorylation of PI3K/Akt and MAPK, which significantly inhibited platelet aggregation through TXA2 production and intracellular granule secretion (ATP and serotonin release). Therefore, we suggest that scoparone is an antiplatelet substance that regulates the phosphorylation of phosphoproteins such as PI3K/Akt and MAPK and is of value as a preventive and therapeutic agent for platelet-derived cardiovascular disease.

Oxidative stress is one of the pathogenic mechanisms of various neurodegenerative diseases, such as Alzheimer's disease. Neuroglia, the most abundant cells in the brain, is thought to play an important role in the antioxidant defense system and neuronal metabolic support against neurotoxicity and oxidative stress. We investigated the protective effect of paeoniflorin (PF) against oxidative stress in C6 glial cells. Exposure of C6 glial cells to hydrogen peroxide (H2O2, 500 μM) significantly decreased cell viability and increased amounts of lactate dehydrogenase (LDH) release, indicating H2O2-induced cellular damage. However, treatment with PF significantly attenuated H2O2-induced cell death as shown by increased cell survival and decreased LDH release. The H2O2- stimulated reactive oxygen species production was also suppressed, and it may be associated with improvement of superoxide dismutase activity by treatment with PF. In addition, an increase in ratio of Bcl-2/Bax protein expression was observed after treatment with PF. In particular, the down-stream of the apoptotic signaling pathway was inhibited in the presence of PF, mostly by reduction of cleaved-poly ADP ribose polymerase, cleaved caspase-3, and -9 protein expression. Furthermore, H2O2-induced phosphorylation of c-Jun N-terminal kinase and extracellular signal-regulated kinase 1/2 was attenuated by treatment with PF. Taken together, neuroprotective effect of PF against oxidative stress probably result from the regulation of apoptotic pathway in C6 glial cells. In conclusion, our findings suggest that PF may be a potent therapeutic agent for neurodegenerative disorders.

Farrerol은 중국에서 거담제로 사용되어온 전통 한약제로 사용된 산진달래(만산홍, Rhododendron dauricum L.)에서 유래된 플라바논이다. Farrerol은 항산화, 항염증 및 항균 작용을 포함한 다양한 생리 활성이 보고되었다. 하지만 farrerol의 MCF-7에 대한 항암 작용은 아직 보고된 바가 없다. 본 연구에서 인간 유방암 MCF-7 세포에 대한 farrerol의 처리가 세포증식을 억제하고 apoptosis를 유도함을 입증하였다. MCF-7 세포에 ferrerol을 48시간 동안 처리했을 때, 이는 통계적으로 유의한 세포증식 효과를 나타냈으며 이의 IC50 값은 145.04±1.4 μM임을 확인하였다. 또한, farrerol이 세포사멸을 유도함을 TUNEL assay와 FACS를 이용한 Annexin V/PI 염색을 통해 검증하였다. 이러한 항암 효능의 작용기전으로써, farrerol의 처리가 BAX/Bcl-2 및 Caspase-3활성화와 PARP 분절화를 증가시켜 세포자살을 촉진한다는 것을 확인하였다. 결론적으로, 본 연구의 결과는 farrerol이 apopotosis 관련 단백질의 활성 및 발현조절을 통해 MCF-7유방암세포에 대한 항암 효능을 갖는다는 것을 보여주고 있다.


Farrerol is a flavanone isolated from the traditional Chinese herb 'Man-shan-hong' (Rhododendron dauricum L.). Farrerol has been reported to have various bioactivities including anti-oxidant, anti-inflammation, and anti-fungal. However, anticancer effect of farrerol has not yet been reported in MCF-7 breast cancer cells. In the present study, we investigated the anti-cancer effect of farrerol on MCF-7 cells. Farrerol decreased viability and induced apoptosis of MCF-7 cells in a dose dependent manner. Ferrerol exhibited a significant anti-proliferation effect with a half-maximal inhibitory concentration (IC50) values of 145.04±1.4 μM in MTT assay, when MCF-7 cells were treated with ferrerol for 48 h. Also, ferrerol induced apoptotic bodies of MCF-7 cells as evaluated by TUNEL assay and Annexin V/PI staining using FACS. By mechanism of action, ferrerol regulated the activation of p38 mitogen-activated protein kinase and altered the expression level of BAX, Bcl-2, and Poly ADP Ribose Polymerase in MCF- 7 cells. In summary, our finding demonstrated that ferrerol has anti-cancer effect through regulating the activation and expression of apoptosis-related proteins in MCF-7 cells.

축산물 중 살균제 prochloraz 및 그의 대사체의 잔류량을 함께 정량분석할 수 있는 단성분 분석법을 개발하고자 하였다. 축산물 중 prochloraz의 잔류분의 정의가 'prochloraz와 2,4,6-trichlorophenol기를 포함하고 있는 대사산물의 합을 prochloraz로 함'이기 때문에 prochloraz 및 대사산물을 모두 2,4,6-trichlorophenol (2,4,6-TCP)로 분해시킨 후 GC/ECD로 정량하는 정밀 분석법을 확립하였다. 대표 축산물인 소고기, 돼지고기, 닭고기, 우유 및 계란 중 prochloraz 잔류분을 acetone으로 추출하고 2,4,6-TCP로 분해한 후 dichloromethane으로 분배하고 aminopropyl SPE로 정제한 다음 2,4,6-TCP를 정량하였다. 본 분석법을 통한 기기정량한계와 분석법정량한계는 prochloraz의 경우 각각 0.01 μg/mL과 0.02 mg/kg이었으며 2,4,6-TCP는 0.005 μg/mL과 0.01 mg/kg이었다. 2,4,6-TCP를 이용한 표준검량선은 0.005-0.2 mg/L 범위에서 결정계수(R2) ≥0.995으로 직선성을 확인하였다. 분석법의 회수율은 분석정량한계 및 정량한계의 10배 처리수준에서 실시하여 모두 90% 이상이었고 변이계수는 10% 이하이었다. 따라서, 본 연구에서 확립된 분석법은 축산물 중 prochloraz 및 대사체를 정량분석하는데 우수한 정확성 및 정밀도를 보였으며, 축산물 중 prochloraz 잔류분석을 위한 정밀시험법으로써 분석개발기준을 충족하였다.


The analytical method was established for simultaneous determination of fungicide prochloraz and its metabolites in several animal commodities using gas chromatography (GC) coupled with electron capture detector (ECD). Samples including beef meat, pork meat, chicken meat, milk, and egg were hydrolyzed with pyridine hydrochloride which converts prochloraz and its metabolites to 2,4,6-trichlorophenol (2,4,6-TCP) because residue definition for prochloraz was 'sum of prochloraz and its metabolites containing the 2,4,6-trichlorophenol moiety, expressed as prochloraz', for compliance with MRLs from animal commodities. Therefore, residual prochloraz was extracted with acetone, decomposed to 2,4,6-TCP, partitioned with dichloromethane, purified with aminopropyl SPE and quantified as 2,4,6-TCP with GC-ECD. The instrumental limit of quantitation and method LOQ (MLOQ) was 0.01 μg/mL and 0.02 mg/kg for prochloraz and 0.005 μg/mL and 0.01 mg/kg for 2,4,6-TCP, respectively. The linearity of the calibration curve was good with R2>0.995 in the range of 0.005- 0.2 μg/mL. Fortification levels of prochloraz were 0.02 mg/kg (MLOQ) and 0.2 mg/kg (10MLOQ) for recovery tests. Overall recoveries of prochloraz were >90% with <10% of coefficient variation (C.V.). This established analytical method was fully validated and could be useful for quantification of prochloraz and its metabolites in animal commodities as official analytical method.

식물 종마다 잎에 미세먼지(PM)를 흡착하는 정도가 서로 다르며 잎을 통해 PM을 흡수할 수 있는 것으로 알려져 있다. PM에 포함된 중금속은 인체 및 식물에 영향을 미칠 수 있으며 입자 크기에 따라 미치는 영향이 다를 수 있다. 따라서 충북대학교 내 도로변에 위치한 회양목 (Buxus koreana), 주목 (Taxus cuspidate), 철쭉 (Rhododendron yedoense), 이팝나무 (Chionanthus retusa)와 같은 가로수 잎에 축적된 PM을 입자 크기(PM>10 및 PM2.5-10)에 따라 분획 및 정량화하였다. 잎에 축적된 크기 별PM의 금속 농도는 유도 결합 플라스마 질량 분석법(ICP-MS)으로 분석하였다. 나무 잎 표면에 축적된 PM>10의 질량은 6.11-32.7 μg/cm2, PM2.5-10의 질량은 0-14.8 μg/cm2이었다. 잎 표면에 홈이 있고 털을 갖고 있는 철쭉이 작은 PM 입자를 잘 유지하고 있었으며 광택이 있는 잎 표면을 가진 주목과 회양목은 많은 PM을 축적하고 있었다. PM은 Al, Ca, Mg, Fe와 같은 지각 구성 원소와 Cu, Pb, Zn와 같은 중금속을 포함하고 있었다. 지각 구성 원소의 농도는 PM>10 입자에서 더 높았고, 중금속농도는 PM2.5-10 입자에서 상대적으로 더 높았다. 잎에 흡수된 Mn, Cd, Cu, Ni, Pb, Zn과 PM2.5-10의 중금속 농도는 유의한 상관관계를 보여 나무 잎을 통해 PM이 흡수될 수 있음을 확인하였다.


It is known that different plant species have ability to deposit different amounts of particulate matter (PM) on their leaves and plants can absorb heavy metals in PM through their leaves. Heavy metals in PM can have toxic effect on human body and plants. Therefore, PM on different roadside trees at Chungbuk national University including box tree (Buxus koreana), yew (Taxus cuspidate), royal azalea (Rhododendron yedoense), and retusa fringetree (Chionanthus retusa) was quantified based on particle size (PM>10 and PM2.5-10). The metal concentration in PM accumulated on leaves was analyzed using inductively coupled plasma-mass spectroscopy. In this study, the mass of PM>10 deposited on the surface of the tree leaves ranged from 6.11 to 32.7 μg/cm2, while the mass of PM2.5-10 ranged from 0 to 14.8 μg/ cm2. The royal azaleas with grooves and hair on the leaf surface retained PM particles for longer time, while the yews and box trees with wax on leaf surfaces accumulated more PM. The PM contained elements in crustal material such as Al, Ca, Mg, and Fe and heavy metals including Cu, Pb and Zn. The concentration of elements in crustal material was higher in the coarser size, while heavy metal concentration was relatively higher in the finer size fraction. The Mn, Cd, Cu, Ni, Pb, and Zn concentrations of leaves and PM2.5-10 were significantly correlated indicating that PM was taken up through tree leaves.

The objective of this study was to investigate the effects of a hypodermic injectable solution comprised of an LPM LB meso solution containing Melissa officinalis L. leaf extract (LPM) on the lipogenesis in the 3T3-L1 cells line. The lipid accumulation measured by oil red o staining in the 3T3-L1 adipocytes treated with LPM, which was reduced in a dose dependent manner and showed 91.7 to 62.9% compared to control group. Its effectiveness with a 50% solution was significantly higher than the hydroxycitric acid (positive control) treatment without showing cell cytotoxicity. In a quantitative real-time PCR, it was demonstrated that the LPM treatment appeared to upregulate the mRNA expression of the adipogenesis-related genes, which included the peroxisome proliferator-activated receptor gamma (50% concentration) while down-regulating the CCAATenhancer binding protein alpha (50% concentration) and the sterol regulatory element-binding protein 1c (10, 25, and 50% concentrations). The results from the current study suggest that the LPM could be useful biomaterials that can inhibit obesity in the 3T3-L1 cells, which could possibly be by regulating the specific adipogenic gene transcription factors.
