  • We consider the reaction-diffusion system of two-component model in one-dimensional space described by $$ (1) u_s = d_1 u_{xx} + f(u, \upsilon) \upsilon_t = d_2\upsilon_{xx} + \gammag(u, \upsilon) $$ where $d_1$ and $d_2$ are the diffusion rates of u and $\upsilon$, and $\gamma$ is the ration of reaction rates. It is interesting the case of that there are differences in the diffusion and reaction rates of u and $\upsilon$.

  • Objective : We examined the putative association between the psychological symptoms and hypoxemia in hospitalized pneumoconiosis patients. Methods : One hundred and nine hospitalized pneumoconiosis patients were divided into two groups according to their level of hypoxemia (PaO2); hypoxemic group consisted of 47 patients with PaO2 lower than 80 mmHg, and comparative group consisted of 62 patients with higher than 80 mmHg. All of them were interviewed with the Hamilton Depression Rating Scale (HAM-D), and completed the Symptom Checklist-90items-Revised (SCL-90-R) and the State-Trait Anxiety Inventory (STAI). The medical data (PaO2, PaCO2, Hb, and Hct), number of hospital days and socio-demographic data as well as scores of the three psychological measurements were compared between the two groups. Results : Hypoxemic patients with lower PaO2 showed higher scores in the HAM-D (p=0.01) and stateanxiety subscale of the STAI (p<0.05). Values of hemoglobin and hematocrit were negatively correlated with levels of trait-anxiety (p<0.05). Thirty patients (27.5%) of total subjects suffered from depression (higher than 18 in the HAM-D), and 46.8% of hypoxemic patients were depressed, whereas 12.9% of comparative group patients were depressed (p=0.01). Conclusion : These results suggest that depression and anxiety might be associated with the hypoxemic mechanism in pneumoconiosis patients.

  • 우울증은 높은 유병률을 가지며 심각하고 만성화 될 수 있는 질병이다. 환자가 증상 없이 기능적 회복이 되어 일상을 영위하기 위해 임상가는 단독요법 이상의 치료 전략이 필요하다. 본 연구에서 SSRI와 aripiprazole 또는 bupropion 부가 요법은 우울증의 증상 호전을 보였다. SSRI와 aripiprazole 부가 요법은 우울증의 전반적 점수의 호전뿐 아니라 세부척도의 핵심 증상에서 bupropion 병합 요법에 비해 더 의미 있는 변화를 보였다. 또한 두 약제 모두 핵심 우울증상이라 할 수 있는 개별증상(우울한 기분, 일과 활동, 정신적 불안)에서 가장 큰 변화를 보였다

  • This experiment was carried out to evaluate the effect of early mouse embryonic development in vitro by co-culture with bovine and porcine oviductal epithelial cells (BOEC and POEC). The 2-cell embryos were collected from the oviducts of the superovulated and mated cultured in D-PBS /15% FCS at 48 hours after hCG injection. The in vitro developmental rate of blastocyst formation in the embryos were examined under the fllowing treatments; 1) TCM 199 added 15% HCS, 2) Ham's F-10 added 15% HCS, 3) MediCult IVF medium, 4) TCM 199 added 15% HCS + BOEC, 5) TCM 199 added 15% HCS + POEC, 6) Ham's F40 added 15% HCS + BOEC, 7) Ham's F-10 added 15% HCS + POEC,8) MediCult IVF medium + BOEC, 9) MediCult IVF medium + POEC. For a comparative study of in vitro development for 96 hours after hCG injection, were cultured with oviductal epithelial cell and media only. The obtained results were 2-cell embryos developed to the blastocyst stage in TCM 199, Ham's F-10 and MediCult IVF medium at the rates of 84.4,83.2 and 81.6%. respectively. The higher developmental rates(91~97%) of blastocyst formation was appeared when the embryos were co-cultured with a monolayer of bovine or porcine oviductal epithelial cells in TCM 199 or Ham's F-10 and MediCult IVF media. No significant difference in developmental rates was shown between bovine and porcine oviductal epithelial cells but significant difference in co-culture system in comparison between media only system and co-cultures. In conclusions, oviductal epithelial cells, BOEC and POEC, when co-culture with mouse early embryos improved the rates of development, blastocyst and hatching. Therefore, it is suggested that co-culture system using oviductal epithelial cells improve early embryonic developtnent in mouse.

  • This study was aimed to investigate the effects of the type O foot-and-mouse disease vaccine (FMDV) on the incidence of abnormal meat such as granuloma or abscess formation at the injection site in pork and its associated economic losses. At 56 d of age, piglets were inoculated with FMDV by one of three administration routes: N-Neck (a conventional needle-syringe injection into the neck), N-Ham (a conventional needle-syringe injection into the ham), and Non-Neck (injection with a needle-free device into the neck). The injection sites were visually examined for the presence of a granuloma or abscess, and the incidence rate of abnormal meat was calculated. The gross weight of the portion of the pork carcasses condemned because of granuloma or abscess formation was measured and multiplied by the weekly sales price to calculate the total economic losses. After implementation of FMDV, the economic losses were approximately six times higher than before implementation. Granuloma or abscess formation was significantly higher in the N-Neck and Non-Neck groups, in which the vaccine was inoculated into the neck area, than in the N-Ham group (N-Neck and N-Ham vs Non-Neck, p<0.05). These results suggest that the incidence of lesions could be reduced if the ham route was used for vaccination.

  • The spherical aberration and optical integer (f) of the electron gun's main lens in color CRT is obtained, using electron beam trajectory. A spherical aberration is obtained from the relation between the object plane and the image of a beam trajectory. To analyze beam profile, 3rd and 1st order coefficient were obtained and used. It is shown that, in practice, they are applied to electron gun design.

  • Objectives : Clinical differences between elderly patients with early and late onset depression have been described although these have been inconsistent. We aimed to compare differences of clinical symptoms using the 17 items Hamilton Rating Scale for Depression(HAM-D-17) between two groups. Methods : Data of 175 elderly patients with a diagnosis of major depressive disorder according to DSM-IV from January 2005 to November 2009 were collected. Seventy five patients were early onset depression and one hundred patients were late onset depression. Depressive symptoms were assessed by the 17-item Hamilton Rating Scale for depression. Results : There were some differences in HAM-D-17 scores between early and late onset depression. Early onset depression patients scored significantly higher in retardation(t = 2.41, p = 0.017) and somatic symptoms( general)(t = 2.37, p = 0.019) than late onset depression patients. Conclusion : We concluded that early onset depression patients have more severe psychomotor retardation and general somatic symptoms than late onset depression patients in Korea. Because of some limitations of this study, further investigations will be needed to validate this study results.

  • 목 적: 사람의 제대유래 줄기세포 (HUC)와 양막유래 줄기세포 (HAM)를 간유사세포로 분화 시키고자 하였다. 연구방법: 산모의 동의아래 만삭 정상 산모로부터 양막 및 제대를 얻고 줄기세포를 분리, 배양하였다. 분리된 세포의 줄기세포로서의 특성을 규명하기 위하여 RT-PCR, 세포면역화학 분석 그리고 중배엽성세포로의 분화능 실험을 하였다. 또한 이들 줄기세포를 분화 배양액에서 간유사세포로 분화 유도 후, 간세포 특이 유전자 발현, 알부민 ELISA, 알부민에 대한 면역블로팅 및 세포면역화학염색 그리고 PAS 염색을 시행하였다. 결 과: 사람의 양막 및 제대로부터 세포를 분리하여 줄기세포로서의 특성을 조사하고, 이들 세포의 지방세포, 연골세포, 골아세포로의 분화능력을 확인하였다. 동일한 분화 배양액에서 HUC과 HAM을 간유사세포로 분화시킨 결과 HUC이 모든 조건에서 HAM보다 알부민과 요소를 더 많이 합성 분비하였다. 간유사세포로의 분화능력이 더 좋은 것으로 나타난 HUC을 가지고 최적의 분화를 유도한 결과 $1.2{\pm}0.8\;{\mu}g/mL$의 알부민을 합성 분비하였고, $8.9{\pm}1.2\;mg/dL$의 요소를 합성 분비하였다. 결 론: HUC과 HAM 모두 알부민을 분비하는 간유사세포로 분화할 수 있었으며, HUC이 더 잘 유도되는 것으로 관찰되었다. 이러한 결과로써 HUC과 HAM을 간질환 환자의 간세포 이식 치료에 필요한 세포치료제로써 이용할 수 있을 것으로 생각된다.
