The acaricidal activity of the mixed plant extracts of Gleditsia japonica var. koraien, Camellia sinensis, Cinnamomum cassia, and Lantana camara, toward the tea red spider mite, Tetranychus kanzawai Kishida was evaluated in laboratory bioassays. Treatments with mixtures 1 and 3 were effective against the adult females of T. kanzawai and yielded 87.0 and 85.6% adulticidal activity at 7 days after treatment, respectively. Mixture 3 revealed 78.7% adulticidal activity. However, mixtures 4 and 5 had lower adulticidal activity than the other treatments. The adult females of T. kanzawai treated with mixtures 1 and 3 produced only 22.5-22.8% as many eggs as did the control females. The residue of the plant extracts tested had low adulticidal activity (16.3-27.2%). All of the plant extracts tested were ineffective against the eggs of T. kanzawai. Treatments with mixtures 1 and 3 were effective against the nymphs of T. kanzawai and led to emergence rates of 20.7 and 25.3%, respectively. These results suggest that mixtures 1 and 3 might be used for the control of T. kanzawai.

<B>Purpose: </B>PET-CT is often used to differentiate benign or malignant thyroid incidentalomas. In this retrospective study, we evaluated whether the <SUP>18</SUP>F-FDG uptake pattern and PET-CT findings improved accuracy over the standardized uptake value (SUV). <B>Methods:</B> <SUP>18</SUP>F-FDG PET-CT was performed on 2,178 subjects from August, 2004, to October, 2007, in Sung-ae Hospital. PET-CT was performed on 806 patients (37%) with suspected or known nonthyroidal cancer and 1,372 healthy subjects (63%) without a previous history of cancer. We investigated the clinical characteristics of patients, history, standardized uptake value (SUV), ultrasonography, and hormone levels in blood. Thyroidal cancer was confirmed by ultrasonography-guided fine needle aspiration and pathology after thyroid operation. <B>Results:</B> The prevalence of focal thyroid lesions on PET-CT was 8.8% (191/2178). Thyroid cancer confirmation was 7.9% (15/191). The maximum SUV of malignant thyroid lesions were significantly higher than that of benign lesions (7.00±3.08 vs. 4.49±1.84, P<0.001). <B>Conclusion:</B> PET-CT image interpretation that includes 18F-FDG uptake and SUV is better than PET-CT alone for differentiating benign and malignant lesions. Thyroid cancer risk increases as SUVmax levels increase. <B>(Ko</B><B></B><B>rean J Endocrine Surg 2008;8:38-42)</B>

Clinical Research Article : The relationship between symphysis-fundal height and intravenous ephedrine dose in spinal anesthesia for elective cesarean section

( Sung Hee Chung ),( Hyeon Jeong Yang ),( Jong Yeon Lee ),( Kum Hee Chung ),( Duk Hee Chun ),( Byeong Kuk Kim ) 대한마취과학회 2010 Korean Journal of Anesthesiology Vol.59 No.3

Background: A decreased lumbosacral subarachnoidal space volume is a major factor in the cephalad intrathecal spread of local anesthetics in term parturients and their subarachnoidal space is decreased due to the compressive effect of huge uteri. Therefore, they show a higher level of sensory block and hypotensive episodes. The purpose of this study is to investigate whether the symphysis-fundal height (SFH) correlates with the highest sensory level and the amount of ephedrine administered under spinal anesthesia. Methods: Fifty-two uncomplicated parturients who consented to spinal anesthesia for elective cesarean section were studied. The SFH of all parturients had been measured just before the spinal anesthesia administered by one person. Hyperbaric bupivacaine with fentanyl 20 μg, was administered for spinal anesthesia. The amount of 0.5% bupivacaine was adjusted according to the patient`s height and weight. The level of sensory block and the amounts of ephedrine to treat hypotension, nausea and vomiting were assessed. Linear regression and correlation analysis were applied to analyze the data. Results: According to the results of correlation analysis, there was no significant correlation between the level of sensory block and SFH. There were statistically significant positive correlations between the amount of ephedrine administered due to hypotension and SFH. Conclusions: In term parturients choosing elective cesarean section, the SFH is not correlated with the sensory level of spinal anesthesia, but is correlated with the amount of ephedrine administered during spinal anesthesia.

Antibacterial and antifungal effects of Korean propolis against ginseng disease

Sung-kuk Kim,우순옥,한상미,방경원,김세건,최홍민,문효정,이성우 한국잠사학회 2019 International Journal of Industrial Entomology Vol.39 No.2

We investigated the anti-microbial activity of propolis against the pathogenic bacteria and fungi on ginseng. We selected six microbials that caused postharvest root rots in ginseng. Propolis extracts were prepared by using the ethanol extraction method. We seeded the bacteria and fungi related to ginseng disease on a specific culture medium, and treated it with propolis extracts by using the paper disc method. Propolis extracts indicate the anti-microbial activity against Paenibacillus polymyxa, Fusarium solani, Rhizoctonia solani AG-1 and Pythium ultimum. However, the anti-fungal activity of propolis is weak on Pseudomonas fluorescens subsp. Cellulosa and Colletotrichum gloeosporioides. As a result, the antimicrobial effects of propolis against microbial that prevent ginseng growth were confirmed. The antimicrobial effects are shown according to the concentration of propolis against root rot. The fungi also showed antibacterial effects in a dose-dependent manner.

Influence of Harvest Time on Pasting Properties of Starch in Colored Rice

Sang-Kuk Kim,Young-Un Song,Se-Jong Kim,Jong-Hee Shin 한국작물학회 2017 한국작물학회지 Vol.62 No.4

The relationship between mean air temperature after heading and starch characteristics of colored rice grains was investigated using three colored rice cultivars. Pasting temperature within each rice cultivar with different harvest times differed. The pasting temperatures of two rice cultivars, Hongjinju and Joseongheugchal, reached the highest at 40 days after heading and decreased during the late harvest time. Distribution of amylopectin in the Hongjinju rice cultivar at the earlier harvest time contained a greater number of very short chains with the degree of polymerization (DP) between 6 and 12 and fewer chains with a DP from 13 to 24 than that of the later harvest time. However, there was little difference in the distribution of the longer chains of 25 ≤ DP ≥ 36 and 37 ≤ DP for latter harvest times compared to that of the earlier ones. It was suggested that the structure of amylopectin affected the varietal differences in patterns of chain length of amylopectin during grain filling. In addition, the control of ripening was different from that causing the pigment effects in the fine structure of amylopectin in the three colored rice cultivars. Larger starch granules were observed in the Joseongheugchal rice cultivar and smaller granules occurred in the Hongjinju rice cultivar. The present study revealed that later harvest times led to a clear increase in the mean granule size of starch in the three colored rice cultivars.

Kuk Hyun Jung,Seung Jong Oh,Kang Kook Choi,Su Mi Kim,Min Gew Choi,Jun Ho Lee,Jae Hyung Noh,Tae Sung Sohn,Jae Moon Bae,Sung Kim 대한외과학회 2014 Annals of Surgical Treatment and Research(ASRT) Vol.87 No.6

Purpose: Surgical site infection (SSI) after open abdominal surgery is still a frequently reported nosocomial infection. To reduce the incidence of SSI, triclosan-coated sutures with antiseptic activity (Vicryl Plus) were developed. The aim of this study was to analyze the effect of Vicryl Plus on SSI after gastric cancer surgery via midline laparotomy. Methods: A total of 916 patients who underwent gastric cancer surgery at Samsung Medical Center between December 2009 and September 2011 were prospectively collected. We examined the occurrence of SSI (primary endpoint), assessments of wound healing (secondary endpoint). They were evaluated postoperatively on days 3, 7, and 30. Results: Of the 916 patients, 122 were excluded postoperatively by screening (out of the study protocol, adverse events, etc.). The remaining 794 patients were enrolled and monitored postoperatively. The cumulative SSI incidence was 11 cases (1.39%; 95% confidence interval [CI], 0.77?2.50) on day 30. Seromas were most frequently detected in wound healing assessments, with a cumulative incidence of 147 cases (18.51%; 95% CI, 15.98?21.39) on day 30. Conclusion: The use of triclosan-coated sutures (Vicryl Plus) for abdominal wall closure can reduce the number of SSIs in gastric cancer surgery.

방광 요로상피세포암: 영상의학적 관점

Kim Dong Won,Yoon Seong Kuk,Kim Sang Hyeon 대한영상의학회 2021 대한영상의학회지 Vol.82 No.5

Bladder cancer is a relatively common cancer type, with a high recurrence rate, that can be often encountered in the imaging study. Accurate diagnosis and staging have a significant impact on determining treatment and evaluating prognosis. Bladder cancer has been evaluated by transurethral resection of bladder tumor for clinical staging and treatment, but it is often understaged when compared with final pathologic result by radical cystectomy. If the location, size, presence of muscle invasion, lymph node metastasis, distant metastasis, and presence of upper urinary tract cancer can be accurately diagnosed and evaluated in an imaging study, it can be treated and managed more appropriately. For an accurate diagnosis, radiologists who evaluate the images must be aware of the characteristics of bladder cancer as well as its types, imaging techniques, and limitations of imaging studies. Recent developments in MRI with functional imaging have improved the quality of bladder imaging and the evaluation of cancer. In addition, the Vesical Imaging Reporting and Data System was published to objectively assess the possibility for muscle invasion of cancer. Radiologists need to know the types of bladder cancer treatment and how to evaluate the changes after treatment. In this article, the characteristics of bladder urothelial carcinoma, various imaging studies, and findings are reviewed. 방광암은 비교적 흔히 진단되는 암이며 재발이 흔해 영상의학적 검사에서 흔히 만날 수 있다. 방광암의 정확한 진단과 병기 평가는 어떤 치료를 할 것인지를 정하고 예후를 평가하는데 큰 영향을 미친다. 방광암의 임상적 병기 평가는 요도경유방광종양절제술로 진단과 치료를 겸해서 이루어졌지만, 저평가되는 경우가 흔히 있다. 수술 전 방광암의 위치, 크기, 근육층침범 유무, 림프절전이, 원격전이, 상부요로 암 유무 등을 영상의학적 검사에서 정확히 진단및 평가할 수 있다면 더욱 적절히 처치 및 관리를 할 수 있다. 이런 정확한 진단을 위해서는영상을 판독하는 영상의학과 의사는 먼저 방광암의 임상적인 특징을 잘 알고 있어야 한다. 그리고 영상 검사들의 종류와 특징, 한계를 알고 있어야 한다. 최근 자기공명영상의 발달로방광 영상의 질 및 방광암의 진단과 평가가 향상되었다. 그리고 방광 이미징 보고 및 데이터시스템이 발표되어 객관적으로 방광암의 근육층 침범 가능성을 평가할 수 있게 되었다. 방광암 치료 종류를 알고 그에 따른 치료 후 변화에는 무엇이 있는지 어떻게 평가하는지도 알아야 하겠다. 이 종설에서는 방광 요로상피세포암의 특징과 다양한 영상의학 검사와 소견에 대해서 알아보고자 한다.

Diversity and Distribution of Wood Decay Fungi in Korea

Kim, Nam Kyu,Kim, Dae Ho,Han, Sang Kuk,Cha, Du Song,Lee, Jong Kyu Institute of Forest Science 2018 Journal of Forest Science Vol.34 No.2

Wood decay fungi were collected in 47 different locations in eight provinces of South Korea from 2011 to 2013. One thousand and five hundreds three fruiting bodies of wood-decay fungi were collected, identified, and classified into 2 phyla, 7 classes, 19 orders, 56 families, 159 genera and 365 species. The most dominant genus and species found were Trametes and T. versicolor. The highest species diversity was found in broad-leaved forest (273 species), and was also found at elevations of 500-1,000 m (227 species). A total of 333 species were collected from broad-leaved trees, 87 species from coniferous trees, and 55 species were collected from both forest types. Gymnopilus liquiritiae was the most dominant species in coniferous trees, while T. versicolor, which was mostly collected from tree trunks below 500 m in elevation, was dominant in broad-leaved trees. Results from the quantitative cluster analysis of wood decay fungi showed that the highest species diversity index was 1.80 in the mixed forests, while the highest similarity among forest types was shown between the broad-leaved and mixed forests.
