Quercetin 3-O-β-(2"-galloyl)-rhamnopyranoside (QGR) is a naturally occurring quercitrin gallate, which is a polyphenolic compound that was originally isolated from Persicaria lapathifolia (Polygonaceae). QGR has been shown to have an inhibitory effect on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated macrophage RAW 264.7 cells. Therefore, this study was conducted to investigate the inhibitory effect of QGR on nitric oxide production and inducible nitric oxide synthases (iNOS) expression in LPS-stimulated Balb/c mice. To accomplish this, 10 mg/kg of QGR was administered via gavage once a day for 3 days. iNOS was then induced by intraperitoneal injection of LPS. Six hours after the LPS treatment the animals were sacrificed under ether anethesia. The serum levels of NO were then measured to determine if QGR exerted an inhibitory effect on NO production in vivo. LPS induced an approximately 6 fold increase in the expression of NO. However, oral administration of QGR reduced the LPS induced increase in NO by half. Furthermore, RT-PCR and western blot analysis revealed that the increased levels of iNOS expression that occurred in response to treatment with LPS were significantly attenuated in response to QGR pretreatment. Histologically, LPS induced the infiltration of polymorphonuclear neutrophils in portal veins and sinusoids and caused the formation of a large number of necrotic cells; however, pretreatment with QGR attenuated these LPS induced effects. Taken together, these results indicate that QGR inhibits iNOS expression in vivo as well as in vitro and has antiinflammatory potentials.

A 3-year-old male Doberman pinscher dog with anorexia and depression was referred to Veterinary Medical Center, Chungbuk National University. Serum biochemistry analysis data showed hypercalcemia, hypercholesterolemia and elevated levels of alanine aminotransferase and gamma-glutamyltransferase. Abdominal and thoracic radiographs and ultrasonographs revealed multiple masses in parenchymal organs including liver, spleen, kidney, sternal and pulmonary lymph nodes. The patient was euthanized with the owner's agreement and autopsy was performed. Various-sized white, soft and ovoid masses were scattered throughout ileocecal area, kidneys, livers, and abdominal and thoracic walls. On cross sections of the involved organs, the masses were discrete and encapsulated with lobular appearances. Histopathologically the neoplasm was diagnosed as extramedullary plasmacytoma. The neoplastic cells were round to oval with basophilic plump cytoplasms and eccentrically located nuclei. The histological diagnosis was confirmed with positive immunohistochemistry against canine IgG in the cytoplasms.

본 연구에서는 페닐아세테이트를 core 물질로 하고 poly(urea-formaldehyde)를 캡슐막 구성물질로 하는 미세캡슐의 제조에 있어서, 교반속도, core/shell 질량비, 계면활성제 농도, 반응시간 등의 공정변수가 캡슐의 크기, 막두께, 표면형태 등의 특성에 미치는 영향을 조사하였다. FTIR 및 TGA에 의하여 원하는 미세캡슐이 제조되었음을 확인하였다. 캡슐의 특성은 광학현미경과 FE-SEM을 사용하여 분석하였다. 교반속도의 증가에 따라 캡슐의 크기와 막두께가 감소하는 것으로 나타났다. 캡슐막 구성물질 질량의 증가는 캡슐막의 두께와 막표면에 부착되는 나노입자의 양을 증가시키는 것으로 나타났다. 계면활성제 농도의 증가에 의하여 캡슐크기와 캡슐막 두께가 감소하는 것으로 확인되었다. 반응시간을 증가시키면 캡슐의 수율과 막두께가 증가하는 것이 관찰되었다. We have performed microencapsulation of phenyl acetate using poly(urea-formaldehyde) as a shell material, and studied the effect of agitation rate, core/shell mass ratio, surfactant concentration, and reaction time on capsule characteristics such as size, shell thickness, and surface morphology. The formation of microcapsules was confirmed by FTIR and TGA, and capsule characteristics were studied by optical microscopy and FE-SEM. Capsule size and shell thickness reduced with increasing agitation rate. As the mass of shell material was increased, shell thickness and nanoparticles on capsule surface increased. Capsule size and shell thickness decreased with increasing the concentration of a surfactant. Increasing reaction time caused increased capsule yield and shell thickness.

As demands for new strategies to control methicillin-resistant Staphylococcus aureus (MRSA) increase, studies that gain insight from gut bacteria regarding growth inhibition and anti-virulence strategies have been reported. Although it was reported in several studies that Lactobacillus strains have antibacterial activity against MRSA, the molecular mechanism under these phenomena is unclear. Here, we evaluated the inhibition effect against MRSA Lactobacillus strains isolated from infant stools and performed a multi-omics study. Firstly, we screened the highest growth inhibitory strain and observed that MRSA growth inhibition effect was not correlated with extracellular pH levels, affected by Lactobacillus strains. In the multi-omics study, it was observed that MRSA significantly upregulated arginine deiminase system, proteins related protein folding and synthesis, etc., and downregulated quorum-sensing system, capsular polysaccharide synthesis proteins, etc. by Lactobacillus strain (L. gasseri 20). In this study, the underlying mechanism involved in growth inhibition and anti-virulence of MRSA mediated by lactobacillus strain was discovered.
