  • This study was conducted to compare nutrient intakes regarding stages of change in dietary fiber increasing behavior. Subjects were consisted of healthy 383 college students (2S0 females and 133 males) in Kyunggi-Do. Stages of change classified by an algorithm based on 6 items were designed each subjects into one of the 5 stages: precontemplation (PC), contemplation (CO), preparation (PR), action (AC), maintenance (MA). Nutrient intakes were assessed by 24-hr recall method. Regarding the S stages of changes, PR stage comprised the largest group $(39.4\%)$, followed by AC $(33.7\%)$, MA$(14.6\%)$, PC$(7.6\%)$, CO$(34.7\%)$. Female were more belong to either AC or MA. The higher stage of change in dietary fiber increasing behavior, the higher self-efficacy. In all male and female, there were no differences in energy, protein, monounsaturated fatty acids, polyunsaturated fatty acids and cholesterol intakes across the 5 stages. But, fiber, postassuim (K), vitamin A and vitamin C intakes of AC or MA were higer than those of PC, CO and PR $Energy\%$ from fat of $PR(25.4\~26.5\%)$ was higher than $20\%$, and those of AC and MA was lower than the other groups. Dietary P/S and ${\varepsilon}6/{\varepsilon}$ 3 ratios of AC and MA were similar to the recommended ratio. Female of PR had the most total saturated fat and palmitic acid and those of MA had the least. Male of PR had the least $\alpha-LNA\;({\varepsilon}3)$ and total ${\varepsilon}3$ fatty acids and those of MA had the most. In male and female in AC or MA, fiber and K intakes from breakfast, dinner and snack and vitamin C intakes from all meals were higher than those of the other stages. These results of our study confirm differences in stages of change in fiber intake in terms of nutritional status. To have lower $energy\%$ from fat, higher intakes of K, fiber and vitamins, desirable ratio of dietary fatty acids, it needs consistent nutritional education leading to the AC or MA of fiber increasing behavior.

  • Objectives : The aim of this study is to investigate the effect of Naegwan-acupuncture stimulation on the relationship of change in electrocardiopgraphy(ECG). Methods : For this purpose, 11 healthy volunteers were acupunctured at Naegwan acupoint using the reinforcing or reducing by inserting the needle in the same direction as the channel runs or in the opposite direction(迎隨補瀉). Then, we measured and observed the change of standard leads Ⅰ, Ⅱ and Ⅲ in ECG. Results : In lead Ⅰ, Naegwan acupuncture treated groups were increased the activity of PR interval and PR segment compared to the control group. In lead Ⅱ, Naegwan acupuncture treated groups were increased the activity of PR interval. In lead Ⅲ, Naegwan acupuncture treated groups were increased the activity of R wave duration, S wave amplitude, ST segment onset, ST segment midpoint, ST segment 80ms and ST segment endpoint. Conclusions : These results suggested that Naegwan acupuncture stimulation plays an important role to the activities of ECG.

  • Background: Breast cancer is the most common malignancy in women worldwide and the second most common cancer in females in India. Receptor status may be important for survival. Objective: To analyse and correlate the clinical and morphological parameters with receptor status in breast carcinoma patients in a tertiary care institution in Southern India. Materials and Methods: This retrospective study involved 320 patients of breast cancer diagnosed in an oncology hospital over a period of $3^{1/2}$ years. Data was analysed using SPSS Version 21. Results: Some 60.6% patients with breast carcinomas belonged to the age group of 40 to 60 years. The most common histological type was infiltrating ductal carcinoma, not otherwise specified, accounting for 84.4% of patients. On immunohistochemistry, estrogen receptor (ER) and progesterone receptor (PR) were expressed in 56.3% and 53.1% of cases, respectively. Conclusions: Breast cancers in India, a developing country, occur in younger women and tend to be more aggressive with lower rates of ER and PR expression and higher histological tumor grades. Both ER and PR status of the tumors had significant associations with the patient age, pathological TNM stage and histological tumor grade.

  • 본 실험실에서는 민간요법으로 말라리아와 성병등의 치료제로 사용되어온 회양목(Buxus microphylla var. koreana Nakai)에서 steroid성 alkaloid인 cyclobuxine D와 nonalkaloid인 buxuletin을 분리하였다. Buxuletin의 가토에 있어서 이뇨작용에 대해서는 본 실험실에서 보고한바 있으며 cyclobuxine D의 약리작용에 대한 보고는 지금까지 전무한 상태이다. 본 실험에서는 새로운 항부정맥 약물의 밭견의 일환으로 cyclobuxine D의 적출 개구리 심장에 대한 작용과 마취시킨 흰쥐의 ECG와 심박동수에 대한 작용을 관찰하였다. Cyclobuxine D는 적출 개구리 심장에 대해 용량의존적 심근 수축력 감소를 나타냈으며 흰쥐에 있어서 현저한 심박동수 감소를 나타냈다. Cyclobuxine D는 흰쥐의 ECG에 있어서 PR interval과 P ${\alpha}T$ interval을 연장시키며, QRS complex와 PR interval의 심박동수에 대한 보상치인 PRc에 대해서는 고용량에서는 연장시키나 그 작용이 현저하지 않다. 이 결과로 보아 cyclobuxine D는 흰쥐의 ECG에서 A-V conduction과 ventricular depolarization에 주로 관여하는 것으로 사료 되며 이는 기존의 antiarrhythmic drugs과 비교해 볼 때 quinidine sulfate와 유사성이 있다고 추정된다.

  • Pseudomonas fluorescens 1-94 induced systemic resistance in chickpea against Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceri by the synthesis and accumulation of phenolic compounds, phenylalanine ammonia lyase(PAL) and pathogenesis related(PR) proteins(chitinase, $\beta$-1,3-glucanase and peroxidase). Time-course accumulation of these enzymes in chickpea plants inoculated with P. fluorescens was significantly(LSD, P=0.05) higher than control. Maximum activities of PR-proteins were recorded at 3 days after inoculation in all induced plants; thereafter, the activity decreased progressively. Five PR peroxidases detected in induced chickpea plants. Molecular mass of these purified peroxidases was 20, 29, 43, 66 and 97 kDa. Purified peroxidases showed antifungal activity against plant pathogenic fungi.

  • More accurate CD (Critical Dimension) control is required for the nanometer-scaled devices. However, since the reflectivity between substrate and PR (Photoresist) becomes higher, the CD (Critical Dimension) swing curve was intensified. The higher reflectivity also causes PR notching due to the pattern of sub-layer. For this device requirement, it was optimized for the thickness, refractive index(n) and absorption coefficient(k) in the bottom anti-reflective coating(BARC; SiON) and photoresist with the minimum reflectivity. The computational simulated conditions, which were determined with the thickness of 33 nm, n of 1.89 and k of 0.369 as the optimum condition, were successfully applied to the experiments with no standing wave for the 0.13um-device. At this condition, the lowest reflectivity was 0.44%. This optimum condition for BARC SiON film was applied to the process for 0.13um-device. The optimum SiON film as BARC to PR and sub-layer could be formed with the accurate CD control and no standing waver for the nanometer-scaled semiconductor manufacturing process.

  • Bone marrow mesenchymal stem cells (BMMSCs) have the capacity for self-renewal and differentiation into a variety of cell types. They represent an attractive source of cells for gene and cell therapy. The purpose of this study is to direct the specific expression of the DsRed reporter gene in $Sca-1^+$ BMMSCs differentiated into a cardiomyogenic lineage. We constructed the prMLC-2v-DsRed vector expressing DsRed under the control of the 309 tp fragment of the rat MLC-2v 5'-flanking region. The specific expression of the DsRed reporter gene under the transcriptional control of the 309 bp fragment of the rat MLC-2v promoter was tested in 5-azacytidine healed-$Sca-1^+$ BMMSCs over 2 weeks after the prMLC-2v-DsRed transfection. The prMLC-2v-DsRed was specifically expressed in the $Sca-1^+$ BMMSCs with cardiomyogenic lineage differentiation and it demonstrates that the 309 bp sequences of the rat MLC-2v 5'-flanking region is sufficient to confer cardiac specific expression on a DsRed reporter gene. The cardiac-specific promoter-driven reporter vector provides an important tool for the study of stem cell differentiation and cell replacement therapy in ischemic cardiomyopathy.
