apple trees. As a result, the colony growth of Phytophthora cactorum was inhibited completely by soaking over 5 s in 31.25 ml/l available chlorine content of NaOCl. Those of H. mompa and R. necatrix were inhibited entirely by soaking over 160 s in 62.5 and 125 ml/l available chlorine content in NaOCl, respectively. Also, inhibition effect on available chlorine in NaOCl among strains of each soil-borne pathogen showed no significant difference and was similar to or better than that of fungicides. -

본 연구에서는 대두 isoflavone의 하나인 daidzein의 콜레스테롤 당전이 효소에 대한 저해효과와 헬리코박터에 대한 항균력을 측정하였다. 콜레스테롤 당전이 효소는 헬리코박터 파이로리의 세포벽 지질성분을 구성하는 $alpha$-glucosyl cholesterol을 생성하는 데 관여하는 효소로 헬리코박터의 생육에 있어서 중요한 역할을 하고 있다. Daidzein을 농도별로 처리하였을 경우, 콜레스테롤 당전이 효소의 활성은 daidzein의 농도에 의존적으로 저해를 나타내었으며, daidzein의 $IC_{50}$값은 $128.5;{mu}M$이었다. 또한 disc diffusion... -

Helicobacter pylori에 대한 항균효과는 열수추출물에서는 Fomitopsis pinicola가 15 mm의 생육저해환으로 가장 높았으며 그 다음으로는 Codyceps militaris, Coriolus versicolor, Phellinus linteus, Fomitella traxinea가 비교적 높은 항균력을 나타내었다. 열수 추출물들의 pH가 낮았으나 항균력이 없는 것으로 보아서 버섯추출물의 수소이온 농도는 항균력에 영향을 미치지 않는 것으로 여겨졌다. Methanol 추출물에서도 Fomitopsis pinicola가 Helicobacter pylori에 대한 생육저해환의 크기가 44 mm로 가장 높은 항균력을 보였다.... -

increase in IFN-γ and MCP-1 at 14 days post-infection. In contrast, compared with the control group, infected TA-treated mice displayed elevated levels of IFN-γ at 3 days post-infection, which continued to increase at 14 days post-infection, as was also observed for tumor necrosis factor. Taken together, the results showing TA activation of cytokine production and inhibition of bacterial proliferation in the host highlight a potential use of TA treatment in the control of Brucella infection. -

Enteritidis in steamed pork using real-time PCR. The inhibitory effect of commonly used Salmonella enrichment broths, Rappaport-Vassiliadis (RV) and Muller-Kauffmann tetrathionate with novobiocin (MKTTn), on real-time PCR was confirmed. The inhibition of PCR was statistically significant (p ＜ 0.05) in RV and MKTTn, as compared with buffered peptone water (BPW) or phosphate-buffered saline. The inhibitory effect of the selective enrichment media was successfully removed by using a modified DNA... -

The anti-inflammatory effects of an ethanol extract of Angelica gigas (EAG) were investigated in vitro and in vivo using croton oil-induced inflammation models. Croton oil (20 μg/mL) up-regulated mRNA expression of cyclooxygenase (COX)-I and COX-II in the macrophage cell line, RAW 264.7, resulting in the release of high concentrations of prostaglandin E2 (PGE2). EAG (1∼10 μg/mL) markedly suppressed croton oil-induced COX-II mRNA expression and PGE2 production. Application of croton oil (5% in... -

Diabetic nephropathy (DN) is the leading cause of end-stage failure of the kidney, but the efficacy of currently available strategies for the prevention of DN remains unsatisfactory. In this study, we investigated the effects of free anthraquinones (FARs) extract, which was extracted from the rhubarb and purified by macroporous resin DM130 with gradient mixtures of ethanol/water as the lelution solvents, in high glucose-cultured glomerular mesangial cells (MCs). The cell proliferation was... -

NOD2 (nucleotide-binding and oligomerization domain 2) was initially reported as a susceptibility gene for Crohn’s disease, with several studies focused on elucidating its molecular mechanism in the progression of Crohn’s disease. We now know that NOD2 is an intracellular bacterial sensing receptor, and that MDP-mediated NOD2 activation drives inflammatory signaling. Various mutations in NOD2 have been reported, with NOD2 loss of function being associated with the development of Crohn’s... -

Gastrointestinal motility consists of phasic slow-wave contractions and the migrating motor complex (MMC). Eupatilin (StillenⓇ) has been widely used to treat gastritis and peptic ulcers, and various cytokines and neuropeptides are thought to be involved, which can affect gastrointestinal motility. We performed a study to identify the effects of eupatilin on lower gastrointestinal motility with electromechanical recordings of smooth muscles in the human ileum and colon. Ileum and colon... -

Shepherd’s purse, Capsella bursa-pastoris (L.) Medik., has been considered a health food for centuries in Asia and is known to contain the isothiocyanate compound sulforaphane. In this study, we evaluated the anti-inflammatory and antibacterial properties of a sulforaphane-containing solution (SCS) isolated from shepherd’s purse. SCS had significant anti-inflammatory activity indicated by the decreased levels of nitric oxide (NO), cytokines (interleukin 1β [IL-1β], IL-6, and IL-10), and... -

This study investigated effect of extract containing quercetin-3-O-Ղ-D-glucuronopyranoside from Rumex Aquaticus Herba (ECQ) against chronic gastritis in rats. To produce chronic gastritis, the animals received a daily intra-gastric administration of 0.1 ml of 0.15% iodoacetamide (IA) solution for 7 days. Daily exposure of the gastric mucosa to IA induced both gastric lesions and significant reductions of body weight and food and water intake. These reductions recovered with treatment with... -

It was evaluated the inhibitory action of quercetin-3-O-Ղ-D-glucuronopyranoside (QGC) on reflux esophagitis and gastritis in rats. QGC was isolated from the herba of Rumex Aquaticus. Reflux esophagitis or gastritis was induced surgically or by administering indomethacin, respectively. Oral QGC decreased ulcer index, injury area, gastric volume, and acid output and increased gastric pH as compared with quercetin. Furthermore, QGC significantly decreased gastric lesion sizes induced by... -

or H. pylori was introduced. The results were compared with RAW 264.7 cells to check if there's cell specificities exist. The expression of HO-1 but not COX-2, iNOS was significantly increased by HMX. Furthermore, HO-1 inhibitor, SnPP IX reduced the HO-1 activity and reversed the survival rate in HMX-treated MKN-74 cells. There's no difference between RAW 264.7 cells and MKN-74 cells. We, thus, concluded that HMX is beneficial for protection from oxidative injury, and induction of HO-1 by HMX in... -

was not affected by defibrotide. The fMLP-induced elevation of intracellular calcium in PMNs was inhibited by defibrotide. The results of this study suggest that defibrotide may have partly beneficial protective effects against reflux esophagitis by the inhibition lipid peroxidation, PMNs accumulation, PMNs adherence to endothelium, reactive oxygen species production in PMNs, inflammatory cytokine production(i.e. interleukin-1β), and intracellular calcium mobilization in PMNs in rats. -

H. pylori의 부착 억제 정도를 실험하였다. 부착 억제 실험의 결과, 난황 항체를 이용하여 H. pylori(NCTC11637, ATCC43526)가 AGS에 부착하는 것을 저해가 가능하였으며 NCTC11637와 ATCC43526 모두 균체 및 외막단백으로 면역접종하여 생산된 항체의 경우 0.5 mg/mL의 농도로 NCTC11637은 80%, ATCC43526은 60% 정도의 부착 억제를 하는 것으로 나타났다. 탈착 실험의 결과도 면역접종을 실시한 난황 항체가 40-60% 정도의 탈착 효과를 보였으며 균체 자체와 외막 단백을 항원으로 사용한 군 사이의 탈착력 차이는 크지 않았다. 그러나... -

동정하였다. 이들 젖산균은 전형적인 생화학적인 특성과 16S DNA의 분석을 통하여 타락에서 분리된 균은 Streptococcus thermophilus LAB kw15로 김치에서 분리된 균은 Leuconostoc mesenteroides LAB kw5로 동정하였다. 이들 분리 균주 배양액을 중성으로 조정한 후 첨가하여 배양할 때 H. pylori의 생육을 현저히 저해하였으며, H. pylori와의 혼합 배양에서도 H. pylori의 생육을 저해하는 것으로 나타났다. 그러므로 이 분리 젖산균의 대사산물이 H. pylori의 생육을 저해하고 있는 것으로 나타나, 기능성 젖산균으로의 활용이 가능할... -

Ascorbic acid is one of the most well-known nutritional supplement and antioxidant found in fruits and vegetables. Calcium ascorbate has been developed to mitigate the gastric irritation caused by the acidity of ascorbic acid. The aim of this study was to compare calcium ascorbate and ascorbic acid, focusing on their antioxidant activity and effects on gastric juice pH, total acid output, and pepsin secretion in an in vivo rat model, as well as pharmacokinetic parameters. Calcium ascorbate and... -

Reactive oxygen species (ROS), generated by infiltrating neutrophils, are considered as an important regulator in the pathogenesis and deveolpment of pancreatitis. The present study aims to investigate whether neutrophils primed by 4β-phorbol 12β-myristate 13α-acetate (PMA) affect the productions H2O2 and lipid peroxide (LPO), NF-κB activation and cytokine production in pancreatic acinar cells, and whether these alterations were inhibited by an antioxidant, N-acetylcysteine (NAC) and... -
The Sensor Kinase GacS Negatively Regulates Flagellar Formation and Motility in a Biocontrol Bacterium, Pseudomonas chlororaphis O6

The GacS/GacA two component system regulates various traits related to the biocontrol potential of plant-associated pseudomonads. The role of the sensor kinase, GacS, differs between strains in regulation of motility. In this study, we determined how a gacS mutation changed cell morphology and motility in Pseudomonas chlororaphis O6. The gacS mutant cells were elongated in stationary-phase compared to the wild type and the complemented gacS mutant, but cells did not differ in length in...
