Purpose: Surgery is the most common risk factor for pulmonary embolism (PE) in patients with a recent venous thromboembolism (VTE). This study reviewed clinical outcomes of preoperative inferior vena cava filter (IVCF) use in patients with acute VTE during abdominal-pelvic cancer or lower extremity orthopedic surgeries. Materials and Methods: We retrospectively analyzed 122 patients with a recent VTE who underwent IVCF replacement prior to abdominal-pelvic cancer or lower extremity orthopedic surgery conducted between January 2010 and December 2016. Demographics, clinical characteristics, postoperative IVCF status, risk factors for a captured thrombus, and clinical outcomes were collected for these subjects. Results: Among the 122 study patients who were diagnosed with acute VTE in the prior 3 months and underwent preoperative IVCF replacement, 70 patients (57.4%) received abdominal-pelvic cancer surgery and 52 (42.6%) underwent lower extremity orthopedic surgery. There were no perioperative complications associated with IVCF in the study population and no cases of symptomatic PE postoperatively. A captured thrombus in the filter was identified postoperatively in 16 patients (13.1%). Logistic regression analysis indicated that postoperative anticoagulation within 48 hours significantly reduced the risk of a captured thrombus (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.08-0.94; P=0.032). Conclusion: A captured thrombus in preoperative IVCF was identified postoperatively in 16 patients (13.1%). Postoperative anticoagulation within 48 hours reduces the risk of captured thrombus in these cases.

Objectives : The purpose of this study is to report on the improvement of respiratory function of a fascioscapulohumeral muscular dystrophy patient after receiving Korean medical treatment. Methods : This study was carried out on a 60 year-old male patient who suffered from fascioscapulohumeral muscular dystrophy. While we carried out Korean medical treatment, we observed $EtCO_2$ (end-tidal carbon dioxide), Vte (exhaled tidal volume) and PIP (peak inspiratory pressure). Results : $EtCO_2$ count decreased from 34 mmHg to 24 mmHg during the treatment period, and PIP count became stable. Vte count also did not worsen in this study. Conclusions : Based on this study, we concluded that Korean medical treatment could be effective in treating fascioscapulohumeral muscular dystrophy patients with respiratory failure.

Lipid droplets called plastoglobules are present in all plastid types. In chloroplasts, they are surrounded by the outer lipid monolayer from and connected to thylakoid membrane. The plastoglobule core contains the neutral lipids, which includes prenylquinones, triacylglycerols, and carotenoids. During stress and various developmental stages such as senescence, the size and number of plastoglobules increase due to the accumulation of lipids. Plastoglobules proteome revealed the presence of metabolic enzymes as well as structural proteins, plastoglobulins/fibrillins. Among the metabolic enzymes, the tocopherol cyclase, VTE1 and the NADPH quinine dehydrogenase, NDC1 have demonstrated that these participate in isoprenoid lipid metabolic pathways at the plastoglobule, notably in the metabolism of prenylquinones (tocopherol, plastoquinol and phylloquinone).

Pulmonary embolism (PE), which can originate as a consequence of deep vein thrombosis (DVT), is the most frequent and potentially fatal venous thromboembolic event. Despite the fact that the incidence of venous thromboembolism (VTE) in Asians is lower than that in the Western populations, a recent epidemiologic study demonstrates an increasing incidence of VTE in the Korean population. Anticoagulants, including low molecular weight heparin (LMWH) and vitamin K antagonist (VKAs), have been the main treatments for PE, however, recently new oral anticoagulants (NOACs) were introduced. We will review how well patients with PE can be managed with the existing anticoagulants and NOACs along with the time span of treatment, which still pose some challenges for clinicians.

Background: A sians were known to have a relatively lower incidence of venous thromboembolism (VTE), and there is insufficient evidence to suggest a specific D-dimer threshold level for screening VTE in patients with acute stroke. Methods: We prospectively enrolled patients with acute ischemic stroke admitted to Jeju National University Hospital. The inclusion criteria were: 1) aged ${\geq}18$ years, 2) admission within seven days of symptom onset, and 3) an initial National Institute of Health Stroke Scale (NIHSS) score >1 for the affected lower limb. Ultrasound scans of the lower limbs and plasma D-dimer assays were performed on days 7-14 and 15-28 after stroke onset. Results: Of 285 patients admitted during the study period, 52 patients met inclusion criteria (mean age 74.5, male 40.4%, median initial NIHSS score 12, and unable to walk unassisted at discharge 76.9%). During 7-14 days, 23 of 52 patients (44.2%) had a D-dimer level above 1.57 mg/L, and 9.6% had a level above 5.50 mg/L. Proximal deep vein thrombosis (DVT) was detected in 3 patients (5.8%, 95% confidence Interval 1.2-16.0%) on ultrasound examination. All DVTs were found in elderly female patients with severe leg weakness. No patient was diagnosed with pulmonary embolism during the study period. Conclusion: The incidence of VTE seems to be very low among Korean patients with acute ischemic stroke. Advanced age, female sex, and severe leg weakness were important risk factors for developing DVT in this study.

The relationship between malignancy and venous thromboembolism(VTE) has been well established. About 20% of all VTE cases are associated with cancer and thrombotic events are the second leading cause of death in cancer patients after death from cancer itself. Effective prophylaxis and treatment will reduce morbidity and may decrease overall mortality. We report a case of VTE in a patient with advanced gastric cancer who treated with low-molecular weighted heparin (LMWH). A 49-year-old man with heartburn was admitted to our hospital. On the endoscopic and radiologic imaging, the patient was diagnosed as an advanced gastric cancer with perigastric infiltration and liver metastasis. During the combination chemotherapy, he had pain and swelling of left lower leg. Doppler ultrasonography showed left posterior tibial venous thrombosis and pulmonary embolism CT showed thromboembolism in subsegmental pulmonary artery branch in right lower lobe. He was treated with LMWH, Dalteparin once daily via subcutaneous injection, and his symptoms was subsided.

Between 1997 and 1998 in Korea, 56 isolates of Escherichia coli were obtained from pig suffering diarrhea. Among those, 38 isolates that showed the hemolytic activity, antimicrobial resistance, and toxin production were studied. Among 38 isolates, thirty-six isolates $(94.7\%)$ were resistant to tetracycline, 27 isolates $(71.0\%)$ were resistant to ampicillin, 26 isolates $(68.4\%)$ were resistant to chloramphenicol, and 21 isolates $(55.2\%)$ were resistant to trimethoprim, while none was resistant to aztreonam, amikacin, and norfloxacin. Among these iso­lates, 21 isolates $(55.3\%)$ were multiple drug resistant to at least four different class antimicrobial agents. Extended spectrum $\beta-lactamase$ producing isolates were not detected in the double disk synergy test. In these hemolytic Escherichia coli, heat-stable enterotoxin $(89.5\%)$ was the most prevalent toxin, followed by vero­toxins $(47.4\%),$ and then heat-labile enterotoxin $(31.6\%).$ Except 8 isolates $(21.0\%)$ which produced ST only, 12 isolates $(31.6\%)$ produced ST and LT, 13 isolates $(34.2\%)$ produced ST, VT, and VTe, and 5 isolates $(13.2\%)$ produced VT and VTe. However, none produced all 4 types of toxin, simultaneously. The predominant serotype could not be determined by the agglutination method. Sixteen isolates $(42.1\%)$ were strongly adhered to T-24 bladder cell and 17 isolates $(44.7\%)$ were to Caco-2 intestinal cell. Especially, 11 strains $(28.9\%)$ were evaluated as strongly adhesive to both T-24 cells and Caco-2 cells. Genes for toxin and the antimicrobial resistance were transferred to clinical isolates of Escherichia coli from human urine by the filter mating method. Results suggest the possibility that antimicrobial resistance and toxin can be transferred from animals to humans by direct con­tact of resistant bacteria as well as gene transfer, although there was no correlation between toxin production, adherent activity, and antimicrobial resistance among hemolytic E. coli isolated from pig suffering diarrhea.

Venous thromboembolism represents as an obstruction of a vein by a blood clot in the blood stream. The most common manifestations of venous thromboembolism (VTE) are pulmonary embolism and deep vein thrombosis (DVT) of the lower extremity. This article reviews the recent advances in this spectrum and introduces new drugs that will be used in venous thromboembolism in the near future.

To evaluate the antioxidant effects of vitamin C, vitamin E and sorghum bran, alone or in combination on chicken sausages, 9 kg of chicken thigh meat was prepared. All thigh meat was divided into seven different batches as follows; no antioxidant (CON); vitamin C (VTC), vitamin E (VTE) or sorghum bran (SOR) at 0.02%; or three different combination ratios of vitamin C, vitamin E and sorghum bran at 0.02% (VT2, 2:1:1; VT4, 4:1:1; VT6, 6:1:1). All cooked sausages were stored at $4^{\circ}C$, and six sausages per treatment were used for chemical analysis on five different storage days. As the addition of vitamin E was increased, sausages stored for 10 d had decreased redness; thereby, VTE showed the lowest CIE $a^*$ (p<0.05). Sausages mixed with vitamins and sorghum bran combinations had lower peroxide and free fatty acid values (p<0.05) when compared to sausages without antioxidants. The TBARS were the lowest in sausages containing vitamin C, vitamin E and sorghum bran at 6:1:1 ratio, and they significantly differed to CON, VTC and SOR treatments (p<0.05). Therefore, our results suggest that meat mixed with vitamins and sorghum bran had more antioxidant activity than the meat mixed with only antioxidant vitamins or without antioxidants.

The p-CIn2Te4 single crystal was grown in the three-stage vertical electric furnace by using Bridgman method. The quality of the grown crystal has been investigated by the x-ray diffraction and the photoluminescence measurements. From the photoluminescence spectra of the as-grown CdIn2Te4 crystal and the various heat-treated crystals, the (Do, X) emission was found to be the dominant intensity in the photoluminescence spectrum of the CdIn2Te4:Cd, while the (Ao, X) emission completely disappeared in the CdIn2Te4:Cd. However, the (Ao, X) emission in the photoluminescence spectrum of the CdIn2Te4:Te was the dominant intensity like an as-grown CdIn2Te4 crystal. These results indicated that the (Do, X) is associated with VTe acted as donor and that the (Ao, X) emission is related to VCd acted as acceptor, respectively. The p-CdIn2Te4 crystal was found to be obviously converted into the n-type after annealing in the Cd atmosphere. The origin of (Do, Ao) emission and its TO phonon replicas is related to the interaction between donors such as VTe or Cdint, and accepters such as VCd or Teint. Also, the In in the CdIn2Te4 was confirmed not to form the native defects because it existed in the stable form of bonds.
