Objectives Impaired lung function(ILF) and sasang constitution(SC) is associated with metabolic syndrome(MS). However, the relationship between ILF and SC is unclear. So, we assessed the relationship between ILF and MS according to SC, and examined whether SC is an independent risk factor for ILF. Methods This study included 1,148 subjects 40years and older who were performed the health examination at Kyung Hee University Hospital in Korea between December 2011 and February 2013. We defined ILF if FVC or $FEV_1$ value were less than lower limit of normal(LLN), and classified ventilatory patterns as obstructive pattern and restrictive pattern. MS was assessed according to AHA/NHLBI criteria. We used multivariate logistic regression to analyze the association of ILF with MS respective to SC types, and to identify the risk of SC types for ILF. Odds ratio(OR) was calculated by adjusting for age, sex, smoking status, drinking, physical activity, and BMI. Results In whole subjects, ILF was associated with MS [OR (95% CI), 1.69 (1.24-2.31) for FVC, 1.67 (1.20-2.33) for $FEV_1$]. And in Taeeum type(TE type) and Soeum type(SE type), ILF was associated with MS [1.63 (1.10-2.42) for FVC, 1.48 (1.01-2.24) for $FEV_1$ in TE type; 6.93 (1.14-42.00) for FVC in SE type], while in Soyang type(SY type), it wasn't. The restrictive pattern was associated with MS in TE type and SE type, while in SY type, it wasn't. Furthermore, TE type and SY type had more risk for ILF than SE type [1.71 (1.12-2.59) for SY type, 1.95 (1.23-3.08) for TE type in FVC; 2.06 (1.26-3.36) for TE type in $FEV_1$; 1.85 (1.21-2.85) for SY type, 2.17 (1.35-3.49) for TE type in Restrictive pattern]. Conclusions These results show that SC is an independent risk factor for ILF, especially TE type and SY type than SE type, and the prevalence of MS is an independent risk factor for ILF in TE type.

Background: Malignant mesothelioma (MM) is an insidious tumor with poor prognosis, arising from mesothelial surfaces such as pleura, peritoneum and pericardium. We here aimed to evaluate the demographic, clinical, and radiological features of patients with MM followed in our center as well as their survival. Methods: The study included 228 patients (131 male, 97 female) who were followed up in our institution between 1993 and 2010 with the diagnosis of MM. Results: The mean age was 59.1 years in men and 58.7 years in women and the sex ratio was 1.4:1 in favor of males. Environmental asbestos exposure was present in 86% of the patients for a mean duration of $40{\pm}20$ years (range: 3-70). Pleural effusion and thoracic/abdominal pain were the most common presenting signs and symptoms (70.2% and 57.8%, respectively). One hundred-thirteen (66%) patients were treated with platinum-based combination chemotherapy (PBCT) plus supportive care (SC) and 67 (34%) patients received SC alone. The median follow-up time was 10.0 months. The median overall survival was significantly improved with PBCT plus SC compared to SC alone (11.4 vs. 5.1 months; p=0.005). The 6, 12, 18, and 24-month survival rates were significantly improved with PBCT plus SC compared to SC alone (72%, 43%, 19%, and 2% vs. 49%, 31%, 11%, and 1%). Conclusion: The survival of patients with MM improved in patients treated with PBCT. The survival advantage continued 12- and 24-month after the initial time of combination chemotherapy.

Objectives The purpose of this study was to identify the research trends and major fields of Sasang Constitutional Medicine by analyzing the topics of papers contained in the Journal of Sasang Constitutional Medicine from the first issue to 2018. Methods To classify the research themes of the paper, theory, Characteristics in Sasang Constitution(SC), Diagnosis in SC, Treatment in SC, etc. categories and subcategories were created. Two researchers reviewed the title, abstract, and text of the paper and classified them according to the category classification. In case of disagreement, the category was determined through discussion with one of the remaining researchers. Results & Conclusions A total of 1,169 papers published in the Journal of Sasang Constitutional Medicine from the first issue to 2018. The number of published papers has increased steadily since the first issue of the Journal of Sasang Constitutional Medicine, and in 2008, the largest number of papers were published, but since then, the number of papers has gradually decreased. When classifying the categories of published papers according to research themes, the Theory field occupied a large portion in the early stages, but since then, the proportion has decreased steadily, and the number of publications has plummeted since 2012. On the other hand, in Treatment in SC field, its proportion has soared to account for about half of the papers since 2001. In Characteristics in SC and Diagnosis in SC fields, since the early 1990s, the number of publications has been consistently maintained.

3D8 single chain variable fragment (scFv) is a recombinant monoclonal antibody with nuclease activity that was originally isolated from autoimmune-prone MRL mice. In a previous study, we analyzed the nuclease activity of 3D8 scFv and determined that a HeLa cell line expressing 3D8 scFv conferred resistance to herpes simplex virus type 1 (HSV-1) and pseudorabies virus (PRV). In this study, we demonstrate that 3D8 scFv could be delivered to target tissues and cells where it exerted a therapeutic effect against PRV. PRV was inoculated via intramuscular injection, and 3D8 scFv was injected intraperitoneally. The observed therapeutic effect of 3D8 scFv against PRV was also supported by results from quantitative reverse transcription polymerase chain reaction, southern hybridization, and immunohistochemical assays. Intraperitoneal injection of 5 and $10{\mu}g$ 3D8 scFv resulted in no detectable toxicity. The survival rate in C57BL/6 mice was 9% after intramuscular injection of 10 $LD_{50}$ PRV. In contrast, the 3D8 scFv-injected C57BL/6 mice showed survival rates of 57% ($5{\mu}g$) and 47% ($10{\mu}g$). The results indicate that 3D8 scFv could be utilized as an effective antiviral agent in several animal models.

Photomixing techniques beating two optical signals with different wavelengths and strong correlations are also very useful techniques to make a continuous wave(CW) signals in the range of millimeter(mm) and terahertz(THz) frequencies. An optical double sideband-suppressed carrier(DSB-SC) technique is one of the popular techniques to generate two optical signals with different wavelengths and strong correlations. DSB-SC signals with strong correlations are generated by a CW modulation of an optical carrier with a local oscillator and an optical modulator. In the previous parers related the DSB-SC for producing the CW signals within the range of mm and THz frequencies, there have been no reports why the optical carrier should suppress. In order to clear that, we have analyzed and measured the characteristics of the mm-wave CW signals made by the DSB-SC photomixing in this paper. From our analysis and measurement results, compared with the case of the DSB with the maximized optical carrier, the power and phase noise have improved about 23.9 dB and 21 dBc/Hz(@ 1 MHz offset frequency) in the case of the DSB with the minimized optical carrier (that is to say, the DSB-SC). Consequently, it is evident reason that the optical carrier should sufficiently suppress to obtain the mm-wave CW signals with the high power and low noise. This paper has given very helpful data to make mm- and THz-wave CW signals using photomixing techniques with the DSB-SC because the reason why the optical carrier should be suppressed is reported in this paper based on the numerical and experimental results.

Shrimp Jeot-Gal is a popular traditional Korean fermented seafood and has been used for seasoning. We isolated a bacterium showing strong extra-cellular fibrinolysis and chitinase activity from shrimp Jeot-Gal and the strain was designated SC082. SC082 was identified as Bacillus licheniformis by 16S rRNA sequence homology search. B. licheniformis SC082 exhibited optimum temperature, pH, and salt concentration at $37^{\circ}C$, pH 7.0, and 6%, respectively. Substrate specificity of the culture supernatant from B. licheniformis SC082 was detected in fibrin, skim milk, and chitin plate. The fibrinolytic activity was highly maintained up to $50^{\circ}C$ at a pH of 7.0 for 3 hr and was stable up to pH 9.0 at $37^{\circ}C$ for 3 hr. The chitinase activity was remarkably induced by addition of 1.0% colloidal chitin and the pH and temperature optima of the enzyme were 5.0 and $45^{\circ}C$, respectively. In sodium dodecyl sulfate-polyacrylamide gel electrophoresis and zymogram analysis, this strain produced three fibrinolytic isozymes and two chitinase isozymes. The approximate molecular weights of the putative fibrinolytic enzymes were 23.0, 62.0, and 72.0 kDa and those of the chitinases were 62.0 and 55.0 kDa, respectively. The antioxidant activity of SC082 was also measured by using 2,2-diphenyl-l-picryl-hydrazyl (DPPH) free radical. The DPPH radical scavenging was slightly increased in a dose-dependent manner.

For the Exp. 1, a total of seventy two pigs (10.53${\pm}$0.02kg average initial body weight) were used in a 38-d growth assay to determine the effects of Saccharomyces cerevisiae (SC) supplementation on growth performance and fecal microbial populations. Dietary treatments included 1) CON (corn-dried whey-SBM based diet), 2) SC0.2 (CON diet+0.2% SC) and 3) SC0.4 (CON diet+0.4% SC). Through the entire experimental period, ADG, ADFI and gain/feed were not significantly different among the treatments. At d 7 and 14 after the onset of the experiment, fecal Lactobacilli sp. count increased as the concentration of SC in the diets was increased (linear effect, P$<$0.01). At d 7 after the onset of the experiment, fecal Escherichia coli count decreased as the concentration of SC in the diets was increased (linear effect, P$<$0.02, quadratic effect, P$<$0.03). For the Exp. 2, forty five pigs (49.71${\pm}$0.45kg average initial body weight) were used in a 28-d growth assay to determine the effects of complex probiotics (CPB, Phichia anomala ST, Galactomyces geotrichum SR59, Thiobacillus sp.) supplementation on growth performance, nutrient digestibility and fecal $NH_3$-N and volatile fatty acid concentrations. Dietary treatments included 1) CON (corn-SBM based diet), 2) CPB0.2 (CON diet+0.2% CPB) and 3) CPB0.3 (CON diet+0.3% CPB). Through the entire experimental period, pigs fed CPB0.3 diet significantly increased their ADG compared to pigs fed CON and CPB0.2 diets (P$<$0.05). Also, apparent digestibility of DM and N in pigs fed CPB0.3 diet was greater than for pigs fed CON diet (P$<$0.05). Fecal $NH_3$-N decreased (P$<$0.05) in the pigs fed CPB diet compared to pigs fed CON diets. Also, pigs fed CPB0.3 diet significantly decreased their fecal propionic acid compared to pigs fed CON diets (P$<$0.05). In conclusion, the results obtained from these feeding trials suggest that the dietary SC for nursery pigs affects fecal microbial population. In finishing pigs, supplemental CPB was effective to improve ADG and nutrient digestibility but to decrease fecal noxious gas emission.
