Thoracic surgery may be greatly facilitated by causing selective atelectasis of the lung being operated on (one-lung ventilation anesthesia). But the tube used for one-lung ventilation is greater outer diameter than conventional endotracheal tube when compare to each other with same inner diameter, so in some young children it is impossible to one-lung ventilation using double lumen tube or bronchial blocker tube because of narrow vocal cord. We performed one lung ventilation anesthesia using conventional endotracheal tube and Fogarty catheter as a bronchial blocker in 11-year old women who received lung biopsy surgery and left lower lobectomy.

This paper proposes a geometrical method for generating and draping the skirt 3D models. The method constructs a 3D basic skirt model using a truncated elliptical cone and generates the various skirt 3D models by controlling the elliptical cone. The B-Spline approximates the 3D drapes which change variously according to the angles and the textiles of the skirts. The mapping sources consist of the textile textures and the skirt 2D model. The 2D models are obtained by mapping the 3D skirt models to the 2D plane. The mapping sources allow us to map the textiles to the 3D skirts. We make the real skirts for the 6 kinds of angles and textiles, and investigate the data of their drape appearances. The investigated data are applied to the virtual skirts. Appearances of the virtual skirts are similar to those of the real.

In order to enumerate the T lymphocytes in bovine peripheral blood lymphocytes(PBL) by E rosette assay, KGRBC were treated with various concentration of 2-aminoethylisothiouronium bromide hydrobromide(AET) and dextran(Dex), singte or combination. The PBL from 10 clinically normal Korean native cattle were formed as low percentage of spontaneous E rosette(6.7±2.4%) in control group, whereas KGRBC treated with 0.1M AET for 20 minutes and 8%Dex were formed as 37.3±2.7% and 45.1±2.1%, respectively. And the synergistic effects were noted no less than 66.5±5.6% when the KGRBC treated with 0.1M AET and 8% Dex subsequently. These results suggest that the KGRBC would be a useful agent for the enumeration of T tymphocytes by E rosette assay in bovine PBI.

It is important to inquiry into the characteristics of several features which are components of a city in studying. However, it was impossible to analyze the existing inquiries in micro because of the limitation of information. Especially, there were not any examples in small scale area and it was very hard to guess the characteristics of the area using the existing information and systems. I presented micro analysis method in small scale area. It was based on not only the production method of land cost and the density of population using GIS is more advanced than existing, but also compared analysis of each feathers through the Grid analysis.

A total of 444 quarters milk samples of 111 dairy cattle in Chonbuk area were examined for infection rete and causative agents of mastitis by "the laboratory procedures used in the Connecticut Mastitis Control Program (CMCP) and California mastitis Test (CMT)". The results obtained were as follows: 1. Of 444 samples, 39.2% had positive CMCP value and 24.4% positive CMT reaction. 2. One hendred and seventy four (39.2%) from 82 cattle (73.9%) were found to infected with mastitis. It was found that 8(1.8%0 of the infected quarters were clinical mastitis and all of the rest were subclinical mastitis. 3. The main causative agents were found to Staphylococcus aureus (63 quarters), Streptococcus agalactiae (56 quarters), non-Str. agalactiae streptococci (54 querters), Escherichia coli (19 quaters), the actual total number of quarters detected as mastitis would be 174, as 18 of these quarters showed multiple infection with two different organisms. 4. Having examined the number of infection quarter per head of mastitis in dairy cattle sampling, major finding were that the average number of infection quarters to total dairy cattle exemined was 1.57 quarters, and that of the infected cattle was 2.1 quarters. Infected quarters in cattle with 1, 2, 3 and 4 were noted 27(32.9%), 28(34.1%), 17(20.7%), and 10(12.3%), respectively.

The present study was conducted to evaluate the anti-inflammatory and anti-arthritic effects of fermented Achyranthes japonica (Miq.) Nakai extract (FAJE). The FAJE was effective in nitrogen oxide (NO) scavenging in RAW264.7 cells. In the case of experimental Sprague Dawley (SD) rats injected with monosodium iodoacetate (MIA), the levels of TNF-α and IL-1β in blood increased in the osteoarthritis-induced group while decreasing in the group administered with FAJE. In addition, MMP-2 and MMP-9 in cartilage tissues increased in the osteoarthritis-induced group, but decreased in the group treated with FAJE. Cartilage examination indicated that the osteoarthritis-induced group exhibited cartilage erosion and cell degeneration, but in the FAJE administered group the tissue, conditions were recovered and cartilage proteoglycan was increased. Therefore, FAJE clearly showed anti-inflammatory effects and this suggests it is effective for recovery from osteoarthritis induced by MIA.

Evaluation of hepatotoxicity of chemicals using hepatic progenitor and hepatocyte-like cells derived from mouse embryonic stem cells: effect of chemicals on ESC-derived hepatocyte differentiation.

Kang, Seok-Jin,Jeong, Sang-Hee,Kim, Eun-Joo,Cho, Joon-Hyoung,Park, Young-Il,Park, Sung-Won,Shin, Hyo-Sook,Son, Seong-Wan,Kang, Hwan-Goo Princeton Scientific Publishers 2013 Cell biology and toxicology Vol.29 No.1

<P>Embryonic stem cell testing is an alternative model system to assess drug and chemical toxicities because of its similar developmental characteristics with in vivo embryogenesis and organogenesis. This study evaluated the toxicity of chemicals at specific developmental stages of mouse embryonic stem cell (ESC)-derived hepatic differentiation; hepatic progenitor cells (HPCs), and hepatocyte-like cells (HCs). The toxic effects of carbon tetrachloride (CCl(4)), 5-fluorouracil (5-FU), and arsanilic acid (Ars) were evaluated by measuring the expressions of Cytokeratin (CK18) and GATA binding protein 4 (GATA-4) and the activities of aspartate transaminase (AST), lactate dehydrogenase (LDH), and alkaline phosphatase (ALP) during the hepatic differentiation process. Non-toxic doses of three chemicals at a range of 25 to 500?μM for CCl(4), 12.5 to 800?nM for 5-FU and 6.25 to 400?mM for Ars were treated. In the CCl(4)-treated group, significant decreases (P?<?0.05) of the marker expression were observed by more than 300?μM from day 10 in CK18 and by more than 400?μM of CCl(4) from day 22 in GATA-4, respectively. However, both markers were decreased (P?<?0.01) by treatments of all doses at day 40. In the 5-FU-treated group, the expressions of two proteins were not affected by any of the doses at day 10 and 22, whereas the GATA-4 expression was decreased (P?<?0.05) by more than 400?nM of 5-FU at days 28 and 40. In the Ars-treated group, the CK18 expression was inhibited (P?<?0.05) by more than 100?mM of Ars at day 22 but showed a tendency to recover. Although the GATA-4 was inhibited by all doses at day 22, the inhibition of GATA-4 recovered at days 28 and 40. ALP activities of three chemicals were significantly increased (P?<?0.05) by a dose-dependent manner. The activities of AST and LDH were prone to be increased by more than 300?μM of CCl(4,) but not affected by all doses of 5-FU except for 800?nM of 5-FU in AST activities. In the Ars, the enzyme activities were significantly increased (P?<?0.05) by more than 50?μM of Ars in AST and more than 6.25?μM of Ars in LDH. The present results indicate that CCl(4) has a more toxic effect on HCs, whereas Ars is more toxic to HPCs. Additionally, in vitro alternative testing using ESC-derived HPCs and HCs could provide useful information on chemical toxicity during the hepatic differentiation process and could be a useful model system for assessing chemical hepatotoxicity.</P>
