Unfavorable healing of maxillary fractures may impose functional and esthetic burdens upon the trauma victim. Malunited maxillary fractures are generally a result of treatment delay, incomplete or inaccurate immobilization of the fracture fragments, or infection. Dysfunctions of mastication, distortions in speech, gross defects in facial contour, and related psychic changes are problems which may require secondary correction. When it is necessary to delay definitive treatment or when inadequate maxillary fracture reduction is recognized within the first week following injury, the maxilla can be mobilized by heavy handed dental manipulation under anesthesia or by elastic traction to an external fixation appliance attached to the maxilla by arch bars or an acrylic splint. But malunited maxillary fracture that have progressed to bony malunion require osteotomy procedure in order to establish normal anatomic relationships. This report parents two cases of malunited unilateral maxillary fracture surgically corrected by unilateral Le Fort I osteotomy.

The highest number of bacterial cell was observed in chicken washed water compared with the natural and chilled water. Fifteen bacterial strains were islated from the chicken processing water. When they were identified by the Bergey's Mannual of determinative bacteriology, they were all identified as the family Enterobacteriaceae; one genus of Citrobacter, three genera of Enterobacter, and four genera of Klebsiella except one isolate unknown. The concentration of Na₂HCIO₄to inhibit all the bacterial strains 30ppm, on the other hand the concentration of CIO₂to retard bacterial growth was 70ppm. The effective concentration of CIO₂was various according to bacterial species.

목 적 : 현재 시중에 판매되고 있는 연무기 기종에 따라 그 성능이 다를 것으로 보고 제품 선택에 도움이 되고자 국내 시판중인 16가지 연무기 기종의 성능을 실험을 통하여 비교하였다. 방 법 : 16가지 연무기/압축기 제품(Pariboy Type 38/Long life, Pariboy Type N/Long life, Pariboy Type N/Salter 8900, Pariboy Type N/LC, Devilbiss pulmoaid-LT/Hudson, Devilbiss pulmoaid/Hudson, Mesmed neb-300/Own, San-up 3040/Hudson, Midas(Basic)/Own, AirJolie2/Hudson, Thomas 1127/Salter 8900, Noel NE-2000/Salter 8900, Omron CX3/Hudson, Chang Woo CWN-100/Salter 8900, Voyage/Mefar, ASI-Pro/Medel jet pluse)을 가지고 Mass output과 입자 크기를 측정하였다. Mass output은 생리식염수 4 mL를 2분간 분무 전, 후의 무게변화를 정밀 전자저울로 측정하였다. 동일한 방법으로 생리식염수 3 mL를 채워 실험하였다. 입자의 크기는 0.9% 생리식염수 4 mL를 채우고 5분간 작동하면서 laser diffraction법을 이용하여 측정하였다. 결 과 : 분당흡입량은 Pariboy type N/Long life이 0.184 mg/min로 가장 높은 값을 보였으며 0.019 mg/min로 가장 낮은 수치를 나타낸 Mesmed Neb-300/Own과는 약 9.6배의 차이를 보였다. Pariboy Type N/Long life이 Mass output이 0.68 mg/min로 가장 컸고 0.13 mg/min으로 가장 작은 수치를 보인 Mesmed-Neb/Own과는 5.2 배 차이가 있었다. 모든 제품은 5분간의 입자의 크기를 측정하였으나 검사시간 동안 입자크기의 차이는 보이지 않았다. $5{\mu}m$ 이하의 입자크기의 최대값은 64%였고 최소값의 연무기는 20%였다. MMAD는 Pariboy Type N/Long life이 $3.76{\mu}m$로 가장 작았으며 나머지 제품은 모두 $5{\mu}m$ 이상이었다. 결 론 : 시중에 판매되는 연무기들의 기능이 다양하므로 제품의 선택에 있어서 그 성능을 고려할 필요가 있다. Purpose : We assessed the dynamic characteristics of 16 nebulizer/compressor combinations currently available in Korea. Methods : The 16 nebulizer/compressor combinations(Pariboy Type 38/Long life, Pariboy Type N/Long life, Pariboy Type N/Salter 8900, Pariboy Type N/LC, Devilbiss pulmoaid-LT/Hudson, Devilbiss pulmoaid/Hudson, Mesmed neb-300/Own, San-up 3040/Hudson, Midas(Basic)/Own, AirJolie 2/Hudson, Thomas 1127/Salter 8900, Noel NE-2000/Salter 8900, Omron CX3/Hudson, Chang Woo CWN-100/Salter 8900, Voyage/Mefar, Chang Woo ASI-Pro/Medel jet pulse) were evaluated in terms of particle size and mass output. In addition, we determined the effects of nebulizer fill volume on mass output. Results : Pariboy Type N/Long life has the highest respirable mass of 0.184 mg/min and Mesmed Neb-300/Own has the lowest 0.019 mg/min. Pariboy Type N/Long life has the highest mass output of 0.68 mg/min and the shortest mass median aerodynamic diameter(MMAD) of $3.76{\mu}m$. All combinations other than Pariboy Type N/Long life produced a MMAD of over $5{\mu}m$. MMAD over a 5 min nebulization ranged 3.76 to $9.83{\mu}m$. There were no significant effects of fill volume on mass output. Conclusion : We concluded that there is a wide variation in performance of nebulizer/compressor combinations. The characteristics of nebulizer/compressor combinations should be considered in selecting products.

In this study, an anti-oxidant and anti-tumor protein Latcripin-3 of Lentinula edodes C91-3 was expressed in Escherichia coli. for the first time. According to the cDNA library, the full-length gene of Latcripin-3 was cloned by the methods of 3'-full rapid amplification of cDNA Ends (RACE) and 5'-full RACE. The structural domain gene of Latcripin-3 was inserted into the pET32 a(+). The functional protein of Latcripin-3 was expressed in Rosetta-gami (DE3) E. coli, evaluated by Western blotting and mass spectrometry. DPPH testing showed that the protein Latcripin-3 can scavenge free radicals remarkably well. The activity of functional protein Latcripin-3 on A549 cells was studied with flow cytometry and the MTT method. The MTT assay results showed that there was a decreases in cell viability in a dose-dependent and time-dependent manner in protein Latcripin-3 treated groups. Flow cytometry demonstrated that Latcripin-3 can induce apoptosis and block S phase dramatically in human A549 lung cancer cells as compared to the control group. At the same time, the cell ultrastructure observed by transmission electron microscopy supported the results of flow cytometry. This research offers new insights and advantages for identifying anti-oxidant and anti-tumor proteins.
Device for Catheter Placement of External Ventricular Drain
Ann, Jae-Min,Bae, Hack-Gun,Oh, Jae-Sang,Yoon, Seok-Mann The Korean Neurosurgical Society 2016 Journal of Korean neurosurgical society Vol.59 No.3
To introduce a new device for catheter placement of an external ventricular drain (EVD) of cerebrospinal fluid (CSF). This device was composed of three portions, T-shaped main body, rectangular pillar having a central hole to insert a catheter and an arm pointing the tragus. The main body has a role to direct a ventricular catheter toward the right or left inner canthus and has a shallow longitudinal opening to connect the rectangular pillar. The arm pointing the tragus is controlled by back and forth movement and turn of the pillar attached to the main body. Between April 2012 and December 2014, 57 emergency EVDs were performed in 52 patients using this device in the operating room. Catheter tip located in the frontal horn in 52 (91.2%), 3rd ventricle in 2 (3.5%) and in the wall of the frontal horn of the lateral ventricle in 3 EVDs (5.2%). Small hemorrhage along to catheter tract occurred in 1 EVD. CSF was well drained through the all EVD catheters. The accuracy of the catheter position and direction using this device were 91% and 100%, respectively. This device for EVD guides to provide an accurate position of catheter tip safely and easily.

<P>Bisphenol A (BPA) has been reported to possess hepatic toxicity. We investigated the hypothesis that BPA, below the no observed adverse effect level (NOAEL), can induce hepatic damage and mitochondrial dysfunction by increasing oxidative stress in the liver. Two doses of BPA, 0.05 and 1.2 mg/kg body weight/day, were administered intraperitoneally for 5 days to mice. Both treatments impaired the structure of the hepatic mitochondria, although oxygen consumption rate and expression of the respiratory complex decreased only at the higher dose. The hepatic levels of malondialdehyde (MDA), a naturally occurring product of lipid peroxidation, increased, while the expression of glutathione peroxidase 3 (GPx3) decreased, after BPA treatment. The expression levels of proinflammatory cytokines such as interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) also increased. In HepG2 cells, 10 or 100 nM of BPA also decreased the oxygen consumption rate, ATP production, and the mitochondrial membrane potential. In conclusion, doses of BPA below the NOAEL induce mitochondrial dysfunction in the liver, and this is associated with an increase in oxidative stress and inflammation.</P>
