  • Unilateral ureteronephrectomy was performed in a dog presented with unilateral hydroureter and hydronephrosis. On laparotomy, severe adhesion of the dorsomedial border of the affected kidney to the abdominal aorta longitudinally and caudal pole of the kidney firmly to the ipsilateral ovary were observed. Since it was not possible to ligate the renal artery and vein separately due to severe adhesion tissue, two mass ligations were applied in the medial border of kidney, and the adhesion tissue was transected distal to each ligature. Then, blunt and sharp dissections were performed to isolate dorsomedial border of the kidney from the abdominal aorta, but they brought out unexpected hemorrhage caused by incision of renal artery and it has been suspected that two mass ligations could not include renal artery, which was adhered to dorsomedial border of the kidney. The hemorrhage was controlled by double ligations and electrocautery. In this case report, we recommend that if isolation of renal vessels is impossible due to strict adhesion of kidney to adjacent tissue, the mass ligation could be chosen to isolate and exteriorize the kidney and placed carefully not only at medial border of the kidney, where the renal vessels come into the kidney anatomically but also additional border of the kidney where adhesion tissues are formed.

  • In recent years, a combination of two demographic phenomena, an increased number of older people in the population and an increase in the incidence of lung cancer with age, has made it mandatory to develop therapeutic modalities with less toxicity for the treatment of inoperable elderly patients with lung cancer. Therefore, we investigated the correlation between COX-2 expression and cytotoxicity of Nimesulide, a specific COX-2 inhibitor. Material and Method: Immunohistochemical staining of COX-2 was performed. After exposure of Nimesulide, XTT analysis, FACS analysis and Hoechst staining were carried out. Result: COX-2 protein was expressed in non-treated A549 cells strongly, but not in H1299. Cytotoxicity of Nimesulide against A549 cell and H1299 cell were similar and $IC_{50}$ of Nimesulide in both cell lines were $70.9{\mu}M$ in A549 cell line and $56.5{\mu}M$ in H1299 cell line respectively. FACS analysis showed $G_0/G_1$ arrest in both cell lines and the S phase cell fraction was decreased. Morphologic assessment of apoptosis by Hoechst 33258 staining, many apoptotic cells were detected in both cell lines. Conclusion: Selective COX-2 inhibitor, Nimesulide, can inhibit the proliferation of non-small cell lung cancer cell lines in vitro. Inhibitory effect of Nimesulide are induction of apoptosis and $G_0/G_1$ arrest. There is no correlation between COX-2 expression and cytotoxicity of Nimesulide, a specific COX-2 inhibitor. Therefore, highly selective COX-2 inhibitors such as Nimesulide can be expected to lead to even greater efficacy of their use as adjuncts to various anticancer angents and radiation therapy for the treatment of high-risk patients.

  • This study was conducted to investigate the morphological characteristics and cultural conditions for artificial fruiting body(synnemata) production of Paecilomyces japonica. In the morphological characteristics of P. japonica, the size of it's conidia was ranged from $5.0{\sim}1.5\;to\;7.9{\sim}2.4\;{\mu}m$. The artificial fruiting body showed yellow in color, shape was confirmed ellipsoidal or obovoid type, and the length was $50.6{\sim}104.5\;mm$. The mycelial growth on the PDA medium treated with pH7, at $25^{\circ}C$ was superior to that of other treatments. The formation period of an artificial fruiting body of P. japonica treated with polypropylene and glass bottle culture was 30 days and 50 days, respectively. The length and number of fruiting body was longer and higher in the polypropylene bottle culture than those of the glass bottle culture. As the results, the artificial fruiting body production in the polypropylene bottle increased 1.2g per bottle compared to that of the glass bottle. It also increased in $100{\sim}400\;lx$ illumination, whereas the elongation of synnemata, pinheading and fruiting body growth were inhibited by continuous use of 900 lx illumination. The results of these experiment indicated that fruiting body formation seemed to be lower as the light intensity increased. The fruiting body formation was also dependent on the light color. There was a higher incidence in red color light and fluorescent light treatment than that of incandescent and blue color light. The fruiting body of the naked barley medium had so much better growth compared to other media that it would be able to use for it's production. The growth of fruiting body was affected by $CO_2$ concentration. It increased after putting the lid on the bottle.

  • To evaluate the antimutagenic effect and hepato protective of bamboo trees and bamboo byproduct, hot-water extracts from four kinds of bamboo [wang-dae (Phyllostachys bambusoides S. et Z.), som-dae (Phyllostachys nigra var. henonis), maengjong-juk (Phyllostachys pubescens) and o-juk (Phyllostachys nigra Munro)] and maengjong-juk extract coated rice were evaluated for antimutagenicity by Ames test using Salmonella typhimurium TA100. Bamboo extracts showed strong antimutagenic activity in the Ames test which MNNG was used as mutagen in the absence and presence of S9 mix. Maengjong-juk extract coated rice diet suppressed the loss of body weight significantly. Food intake was increased in maengjong-juk extract coated rice supplemented group but showed no significant differences between control and maengjong-juk extract coated rice diet groups. Food efficiency of maengjong-juk extract coated rice supplemented group was significantly higher than that of the control group. Liver weight was significantly increased by maengjong-juk extract coated rice diet administration. Plasma GOT & GPT activities of rabbit were significantly suppressed in maengjong-juk extract coated rice supplemented group. These results suggest that bamboo trees extracts and maengjong-juk extract coated rice are bioavailable resource on treatment of cardiovascular disease, such as atherosclerosis and hypercholesterolemia.

  • The purpose of this descriptive study was to evaluate the clinical validity of QSCCII (Questionnaire for the Sasang Constitution Classification), whose high accuracy as a constitutional diagnostic tool has been recognized by medical professionals. The subjects of this study were 568 clients from an A university hospital in Suwon. Of the subjects, 259 were health center visitors and 292 were ambulatory clinic visitors. Data were collected using self-reported questionnaire and were analyzed by $X^2$-test and one-way ANOVA. The results of this study as follows: 1. In 4 types of constitution, Soeumin type was found in 41.5% of the subjects. Taeumin type in 39.2%.,and Soyangin type in 19.2%, respectively. There was no Tayangin type found in this study. There were no significant differences on types of constitution by demographic characteristics such as age, sex, marital status, education, religion, and economic status. 2. As for 15 item-selective questionnaire, there were statistically significant differences on the response rate of the 12 items, except items such as A4, A11 and A14, by the types of constitution. When the subjects' own criteria on their constitution were compared to the given constitutional criteria on each item, 4 items such as A6, A11, A13 and A14 were advisable to be excluded from the questionnaire or to be reunited to the other criteria. In the meanwhile, 3 items such as A7, A18 and A15 were desirable to be re-categorized to the other constitutional types and reconstructed to the QSCC II questionnaire. 3. In terms of 106 true-false questionnaire, there were statistically significant differences on the response rate of 46 items by the types of constitution. The 46 items include 15 items (32.6%) of the domain of 'handling something/strength and weakness', 4 items (8.7%) of the domain of 'interpersonal relationship', 9 items (19.6%) of the domain of 'state of mind at ordinary times', 2 items (4.3%) of the domain of 'distinctive emotional characteristics' area, 11 items (23.9%) of the domain of 'specific behavioral trait' and 5 items (10.9%) of the domain of 'physical characteristics'. Therefore, the areas of 'handling something/strength and weakness' and' specific behavioral trait' mainly contributed to the classification of constitutional type. 4. When the 106 true-false items were simplified to the 46 items, statistically significant differences were found on the rate of items allocated to the 3 types of constitution. The rate of selection assigned to the 3 constitutional types of the simplified 46-item questionnaire was higher than that of the original 106-item questionnaire. Conclusions; It was concluded that the rate of selection of each lay person about his own constitutional type would be still higher even though the simplified items of QSCC II questionnaire were applied. If more replicated studies are conducted on the diverse population using the simplifying QSCC II questionnaire in the future, a more simplified standardized Sasang Constitution Questionnaire that is available to the public rather than to medical staffs in the clinical settings could be developed. Moreover, the simplified scale will help nurses deliver more efficient nursing care by providing a more rapid way of health assessment.

  • The lab scale experiments to investigate the geochemical reaction among supercritical $CO_2$-mineral-brine which occurs at $CO_2$ sequestration sites were performed. High pressurized cell system (l00 bar and $50^{\circ}C$) was designed to create supercritical $CO_2$ in the cell, simulating the sub-surface $CO_2$ storage site. From the high pressurized cell experiment, the surface changes of Ca-feldspar, amphibole (tremolite) and olivine, resulted from the supercritical $CO_2$-mineral-brine reaction, were observed and the dissolution of minerals into the brine was also investigated. The mineral slabs were polished and three locations on the surface were randomly selected for the image analysis of SPM and the surface roughness value (SRV) of those locations were calculated to quantify the change of mineral surface for 30 days. At a certain time interval, SPM images and SRVs of the same mineral surface were acquired. The secondary minerals precipitated on the mineral surfaces were also analyzed on SEM/EDS after the experiment. From the experiments, the average SRV of Ca-feldspar increased from 2.77 nm to 20.87 nm for 30 days, suggesting that the dissolution of Ca-feldspar occurs in active when the feldspars contact with supercritical $CO_2$ and brine. For the amphibole, the average SRV increased from 2.54 nm to 8.31 nm and for the olivine from 0.77 nm to 11.03 run. For the Ca-feldspar, $Ca^{2+}$, $Na^+$, $Fe^{2+}$, $Si^{4+}$, $K^+$ and $Mg^{2+}$ were dissolved in the highest order and $Si^{4+}$, $Ca^{2+}$, $Fe^{2+}$ and $Mg^{2+}$ for the amphibole. Fe (or Mg) - oxides were precipitated as the secondary minerals on the surfaces of amphibole and olivine after 30 days reaction. Results suggested that $Ca^{2+}$, $Fe^{2+}$ and $Mg^{2+}$ rich minerals would be significantly weathered when it contacts with the supercritical $CO_2$ and brine at $CO_2$ sequestration sites.

  • Objectives: The study aimed to explore dental status and denture satisfaction in some rural elderly people. Methods: A total of 546 participants aged over 65 years was surveyed cross-sectionally. The subjects were surveyed with regard to their denture satisfaction by a structured questionnaire. The Wilcoxon or Kruskal-Wallis test was used for analysis. Results: As for respondents' satisfaction for dentures by the Likert scale of 5 score, aesthetic satisfaction (3.73) was highest, followed by general satisfaction (3.56) and masticatory functions satisfaction (3.45). In addition, the educational level, occupation, monthly income, the number of remaining teeth, use of denture variables have statistically significant difference in the denture satisfaction of those elderly people interviewed. Conclusions: The results showed that denture satisfaction in some rural elderly people was different in each categories. Consequently, providing tailor-made oral health education programs for the effective denture management of the elderly people should be needed in order to improve the quality of life of the aged.

  • Epimedium koreanum Nakai is a wild medicinal plant commonly consumed in South Korea due to its health beneficial effects. In the present study, the antioxidative, antimutagenic and immunological activities of E. koreanum Nakai extracts were investigated for their use in food. The yields of icariin compounds from the ethanol extract as well as the ethyl acetate, butanol, hexane, water, and chloroform fractions of E. koreanum were 27.9, 2.5, 1.7, 1.4, and 1.3 ${\mu}g/g$, respectively. The icariin components (295.5 ${\mu}g/g$) were collected from the ethyl acetate fraction by thin layer chromatography (TLC) and analyzed via high performance liquid chromatography (HPLC). The antioxidant activities of each fraction were as follows: ethyl acetate (49.0 ${\mu}g/mL$), butanol (59.2 ${\mu}g/mL$), hexane (119.8 ${\mu}g/mL$), water (122.0 ${\mu}g/mL$), and chloroform (138.5 ${\mu}g/mL$), based on $RC_{50}$ ${\mu}g/mL$. Icariin, isolated and identified as the main component, showed strong antioxidant activity with a $RC_{50}$ value of 15.3 ${\mu}g/mL$, which was higher than those of ascorbic acid (19.5 ${\mu}g/mL$) and ${\alpha}$-tocopherol (18.2 ${\mu}g/mL$). In an Ames test, none of the fractions produced mutagenic effects on Salmonella Typhimurium TA98 and TA100. In an immunomodulating activity test, the effects of E. koreanum Nakai on B cells (Rhamos) and T cells (Jurkat) were investigated. These results show that the growth and viability of B and T cells were increased by isolated icariin components for 1.27 and 1.28 fold, respectively. These results also provide preliminary data for the development of E. koreanum Nakai as an edible food material.

  • Typhoon Sanba was selected for describing the Korea Meteorological Administration (KMA) Global Data Assimilation Prediction System (GDAPS) model bias tendency in forecast for the interaction between mid-latitude trough and movement speed of typhoon. We used the KMA GDAPS analyses and forecasts initiated 00 UTC 15 September 2012 from the historical typhoon record using Typhoon Analysis and Prediction System (TAPS) and Combined Meteorological Information System-3 (COMIS-3). Sea level pressure fields illustrated a development of the low level mid-latitude cyclogenesis in relation to Jet Maximum at 500 hPa. The study found that after Sanba entered the mid-latitude domain, its movement speed was forecast to be accelerated. Typically, Snaba interacted with mid-latitude westerlies at the front of mid-latitude trough. This event occurred when the Sanba was nearing recurvature at 00 and 06 UTC 17 September. The KMA GDAPS sea level pressure forecasts provided the low level mid-latitude cyclone that was weaker than what it actually analyzed in field. As a result, the mid-latitude circulations affecting on Sanba's movement speed was slower than what the KMA GDAPS actually analyzed in field. It was found that these circulations occurred due to the weak mid-tropospheric jet maximum at the 500 hPa. In conclusion, the KMA GDAPS forecast tends to slow a bias of slow movement speed when Sanba interacted with the mid-latitude trough.

  • Purpose: To compare the obliquity of femoral tunnels prepared with transtibial (TT) versus anteromedial portal technique (AM) using x-ray in single-bundle anterior cruciate ligament (ACL) reconstruction. Materials and Methods: Among one-hundred thirty two patients who were undergoing ACL reconstruction from January 2007 to December 2009, thirty patients using TT and twenty patients using AM, those who had single-bundle ACL reconstruction, were evaluated with plain radiographs including anteroposterior, intercondylar notch and lateral view to compare the obliquity of bone tunnels. Results: The mean coronal obliquity of femoral tunnel for TT was $71^{\circ}$ (range; $65^{\circ}{\sim}77^{\circ}$), while for AM was $51^{\circ}$ (range; $39^{\circ}{\sim}60^{\circ}$) and the mean sagittal obliquity of femoral tunnel for TT was $22.7^{\circ}{\pm}7.8$, while for AM was $30.2^{\circ}{\pm}6.9$, their differences between them were statistically significant (P<0.05). However, there were no differences between two techniques on the tibial tunnel obliquity in coronal and sagittal plane. Conclusion: Anterior cruciate ligament reconstruction using AM portal technique allows more horizontally oriented and divergent femoral tunnel compared to that of transtibial technique. This seems to enable the graft placement into the femoral footprint and preserve the posterior cortical wall.
