This study was undertaken to improve the perceived value of halophytes and contribute to the activity of the local economy by analyzing the antioxidant activity and mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina that grow wild on the mud flats and coastal areas. The total phenolic compound content found in each order is as follows: Suaeda japonica (3.674∼5.989 mg TAE/g dry wt.), Tetragonia tetragonoides (2.515∼4.471 mg TAE/g dry wt.), and Spergularia marina (2.450∼4.067 mg TAE/g dry wt.); DPPH radical scavenging and ABTS cation radical scavenging activities were also recorded in the same order. In the case of minerals, Iron(Fe) was relatively high in Suaeda japonica (960.1∼1,346.7 mg/kg), Manganese(Mn) in Tetragonia tetragonoides (197.1∼574.8 mg/kg), and Zinc(Zn) was relatively high in Spergularia marina (63.19∼216.56 mg/kg). It was confirmed that the mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina was significantly higher than that of Chinese cabbage, lettuce, leek, and spinach.

This study was done to investigate the effects of caffeine ingestion on the expression of GLUT-4 in rats' skeletal muscle(soleus m) and blood insulin level after 12 hr fasting condition and one hour treadmill running. Total 19 rats(Sprague-Dawley) who were 7week Did were used for experimental subjects and raised for 1week in the room controled the air temperature and relative humudity(22℃ and 50%). They were divided three groups ; 12hr fasting group(F group, n=5), fasting+exercise group(FE, n= 7) and fasting+caffeine+exercise group(FCE group, n=7). FG and FCE group performed treadmill running for one hour and the treadmill speed was 18m/min that was supposed to be moderate exercise to rats. Each Dr rats in FCE group was forced to he given the caffeine solution(5mg/kg, Sigma Chemical co.) through stainless steel tube directly to their stomachs one hour before treadmill exercise. Immediately after treadmill running, we anesthetized them with the mixed solution(Ketamin 80g/kg and Rompun 5ml/kg) to draw 3ml blood from heart four insulin analysis and then obtained the rats' soleus muscle for GLUT-4 expression. We found that FCE group showed significantly higher GLUT - expression then the other groups and FE group showed the lowest GLUT-4 expression. This rusults suggest that the endurance type of exercise in fasting condition inhibit the GLUT-4 expression in working muscle and the caffeine helped to facilitate the GLUT-4 expression during endurance type of exercise. The future studies needed to confirm the action of caffeine to increase the GLUT- 4 and the mechanism.

Syphilis is a chronic systemic infectious disease caused by Treponema pallidum. Syphilitic involvement of the stomach can occur via the blood flow in the primary or secondary period of syphilis, but its incidence is very rare. Gastric syphilis should be considered in patients at risk of sexually transmitted disease who complains of abdominal pain, nausea and vomiting and in whom unusual endoscopic or radiographic features are found. Because gastric syphilis has no pathognomic clinical findings and it can simulate gastric cancer or lymphoma, it’ s not so easy to diagnose. If diagnosed, however, gastric syphilis can be easily treated with proper antibiotics. We report on a case of gastric syphilis that manifested epigastric pain, anorexia and weight loss. It was initially thought to be lymphoma, but it was correctly diagnosed by serologic testing and progress.

Objective: This study was performed to investigate the clinical significance and timing of HPV test for follow up of patients after LEETZ treatment in CIN lesion Methods: From January 2005 to December 2008, 105 patients with CIN were treated with LLETZ at Kosin university gospel hospital, Busan, Korea. After LEETZ, HPV test and Pap smear were done after 3months. Every HPV typing was done by HPV DNA chip. Results: A total of 105 cases were enrolled in this study. There were 25 patients with CINⅠ, 38 with CINⅡ, 42 with CINⅢ. Mean age was 41.95 years (range, 23-71 years) at the time of LEETZ. Positive HPV DNA was found about 72.4% before LEETZ procedure and subtype 16 was the most common type (10.5%), follow by subtype 18 (6.6%) and subtype 58 (6.6%). During follow up after LEETZ, 65.6% had negative result after 3 month, 72.1% after 6 month, 73.9% after 9 month, 77.1% after 12 month, 79.2% after 15 month, 79.6% after 18 month, and 80.4% after 24 month. There were 2 cases of abnormal pap smear among persistent positive HPV DNA cases and no abnormal pap smear results in negative HPV DNA cases during follow up. Conclusion: Positive HPV DNA was found about 72.4% before LEETZ procedure and subtype 16 was the most common type (10.5%), follow by subtype 18 (6.6%) and subtype 58 (6.6%). We suggest that HPV DNA test is recommended per 6 Months, and close observation is recommended in persistent positive HPV DNA test cases.

The purpose of this study was to evaluate the effects of diet condition and caffeine ingestion prior to long distance treadmill running on the GLUT-4 protein expression in Sprague-Dawley rats' soleus muscle. Total is rats were used For subjects and assigned to six groups: Fasting control(FaC group), feeding control(FeC), asting+exercise(FaE), feeding +exercise(FeE), Fasting +caffeine+exercise(FaCE), and Feeding+caffeine+exercise(FeCE). Each animal belongs to fasting group was forced to be in fasting state at least for 14 hours, The food was provided to each rat in feeding group 12minutes prior to treadmill running and the caffeine was ingested through the stainless steel tube 60minutes prior to exercise. All rats in exercise groups were forced to perform treadmill running for B9 minutes at the speed of 18m/min, and 0%grade, immediately after exercise, all animal was anesthetized by Chlorofolm (DC Chemical, Co, Ltd) and about 10ml of blood was drawn from each animal's heart and than soleus muscle was exposed and separated from the rat's leg. we found that the GLUT-4 in feeding groups increased much significantly compared to fasting groups(p<.05). The exercise in fasting state appeared to suppress the expression of GLUT-4 protein different from the exercise in feeding state. Cafreine ingestion prior to treadmill running of 60 minutes induced the significant increase or GLUT-4 protein expression both in fasting or feeding states.

Efficient utilization of the scoria which are naturally abundant in parasitic volcano area of Cheju-do was tried to be linked with purification of the waste water contaminiating environment. A packed column for waste treatment was manufactured using scoria as medium, and the used waste water was the extract of a brown alga (Ecklonia cava) which is a raw material of sodium alginate. In this study the removal efficiency of suspended solid(SS), biological oxygen demand(BOD), and chemical oxygen demand(COD) was investigated under different conditions of medium size and operation time, The following results were obtained. 1. The smaller size of the medium gave the higher efficiency of water treatment. 2. The removal efficiency of SS was higher than that of BOD or COD at specific medium size. 3. The scoria was more effective on the removal of undissolved solid than dissolved one. 4. Filtration ability of the packed column was not decreased even after 5 day' continuous operation

연구배경: 제대혈은 골수에 비해 많은 장점을 가지고 있음에도, 이식 후 성적에 있어 총세포수에 의해 좌우되며, 한 개의 태반으로부터 얻을 수 있는 총세포수의 한계가 있어 주로 소아에 국한되고 있다. 따라서 제대혈 응용의 확대를 위해 생착량을 늘이기 위한 방법으로 다중공여자에 의한 제대혈 혼합이식을 늘일 수 있는지 연구하기 위하여, 본 연구에서는 주조직적합성 형별로 조합된 제대혈을 NOD/ SCID 생쥐에 이식하는 방법으로, 혼합생착의 가능성을 연구하였다. 방법: 조합된 2개 공여자로부터 얻어진 제대혈들을 단일이식 및 혼합이식하여, 혼합이식된 숙주에 생착된 세포를 PCR-SSOP 방법을 사용하여 공여자 별로 추적하였다. 또한 각 공여자세포의 상대적 생착비율을 대조군인 단일제대혈 이식에서 얻어진 생착량과 비교하는 정량적 비교도 함께 하였다. 결과: 총단핵구를 혼합이식한 실험군에서는 주조직적합성의 일치도에 관계없이 한쪽공여자의 세포가 다른쪽에 비해 우세한 편향생착을 보였다. 그러나 임파구를 비롯한 Lineage 양성세포를 제거한 실험군에서는 주조직적합성의 불일치에도 불구하고 뚜렸한 생착의 공존이 관찰되었다. 결론: 본 연구는 제대혈의 생착량을 증가를 목적으로 총단핵구를 혼합이식할 경우 한쪽공여자의 세포에 의해 편중되며, 이것을 이식 후 생착과정에서의 두 종류의 세포의 경쟁에 의해 초래된다는 것을 보이고 있다. 또한 이러한 경쟁은 제대혈에 포함되어 있던 임파구들에 의한 것이며, 생착공존을 위하여는 공여자간 주조직적합성의 일치도 보다, 임파구의 제거가 더 중요하다는 것을 보여주고 있다. Background: Although umbilical cord blood (UCB) has been an attractive alternatives for bone marrow cells, application is limited to pediatric case due to limitation in total number of nucleated cells, that is a single most important factor for outcomes of UCB transplantation. Therefore, increasing overall engraftment by mixed transplantation of UCB derived from multiple donor should comprise one strategy to circumvent the posed limitation of UCB transplantation. In order to investigate the feasibility of establishing co-engraftment by multi-donor UCB cells, we carried out a xenotransaplantation study using NOD/SCID mice for systemic analysis of results on the input-based control of single unit transplantation. Methods: UCB units with various extent of HLA-matchings were co-transplanted into NOD/SCID mice along with single unit transplantation control. The relative contributions of engraftment by cells from each donor-derived were analyzed by HLA polymorphism using PCR-SSOP. Results: In all HLA-based mixed transplantation of total nucleated UCB cells, engraftment of one donor predominated over the other despite that equivalent amount of engraftments were achieved by single donor transplantation. When lineage depleted UCB units were co-transplanted, significant degree of co-engraftments were observed regardless of HLA disparity. Conclusion: Our result show that one donor cells dominate over the other in mixed UCB transplantation and that it is due to competition between donor cells during post-transplantation process. Our results suggest that immune cells contained in UCB unit mediate such competitioin and that 6 locus HLA matching would not be sufficient to prevent the competition.
