This paper investigates the attitudes of medical users toward Korean oriental medicine and traditional Chinese medicine and their future demand. The subjects are 404 university students both in Korea and in China. The items that were questioned in this paper were the attitudes toward Korean oriental medicine and traditional Chinese medicine, the experience of using the medicine, the reason they used the traditional medicine, the factors that made them satisfied with the medicine, and the future plan for using the traditional medicine. The reason the university students were selected as subjects was that they have more possibilities as future users of the traditional medicine. This paper show that Chinese students have more positive attitude toward the traditional medicine than Korean students. The Koreans' experience rate of using the traditional medicine was comparatively high and the subjects in both the countries used the western medicine for the symptoms of a cold and dental problems. For the illness of stomach, Korean and Chinese subjects used the traditional medicine and the western medicine half and half. This paper presented the subjects with the common 14 diseases that they can have and asked which medicine they will use when they have the diseases. The results of analysis indicate that the subjects tend to use different medical institution according to the diseases. The subjects in Korea and China selected different medical institution for the same disease. From the analysis of the questionnaire, it can be seen that there are some differences between Koreans and Chinese in using the medical institution, which results from the difference in medical culture and the relationship between the traditional medicine and medical users could be figured out.

Objective: The Id family of helix-loop-helix proteins are thought to affect the balance between cell growth and differentiation by negatively regulating the function of basic-helix-loop-helix (bHLH) transcriptional factors. The aim of this study was to investigate the expression pattern of Ids (Id-1, -2, -3, and -4) in preimplantation mouse embryos at mRNA and protein levels. Methods: Oocytes and preimplantation embryos were collected from reproductive organs of female ICR mice following superovulation. RT-PCR was performed to investigate the mRNA expression patterns of Id genes and their protein were localized by immunofluorescence analysis. Results: Id-1 and Id-3 mRNAs were strongly expressed at the germinal vesicle (GV) oocyte and the blastocyst stages. Id-2 mRNA was expressed throughout preimplantation embryo development, but Id-4 was not expressed. Immunofluorescence showed that Id-1 and Id-2 were predominantly localized in cytoplasmic region, but the immunofluorescence signal of Id-3 was weak throughout preimplantation embryo development. Conclusion: These data show for the first time that Ids are expressed in preimplantation mouse embryos and suggest that Ids may play an important role in early preimplantation embryo development and uterine physiological changes.

Glycation이란 단당류의 카보릴기와 아미노산의 입실론 아미노기가 공유결합에 의하여 형성되는 반응으로 이는 단백질의 생리적 기능을 변화시키며 아울러 당뇨합병증을 유발한다. 본 연구에서는 warfarin과 dansylsarcosine의 단백질결합에 미치는 glycation의 영향을 평형투석법을 이용하여 연구하였으며 평형투석은 섭씨 37도의 진탕수조에서 3시간 동안 실시하였다. 약물의 농도가 알부민의 농도보다 높을 경우, $50{\pm}16%$가 glycation된 알부민은 $8.5{\pm}5.28%$ glycation 알부민을 함유한 정상알부민에 비해 약물과의 결합도가 낮았으나 warfarin의 농도가 알부민의 3배가 될 경우에만 유의성이 인정되었고(P<0.05) 6%의 차이를 보였다. 본 실험에 나타난 glycation에 의한 유리약물의 미미한 상승효과는 glycated albumin 농도가 낮은 생체내의 여건과, 실제로 사용되는 약물의 적정 치료농도가 낮고 또한 과도한 유리약물은 신장을 통하여 신속히 배설되는 이유로 당뇨환자의 신기능 손상이 없는한 glycation에 의한 유리약물의 상승은 약물중독의 위험요소로 작용되지 않으리라 생각된다.

Phytoestrogens, especially soy-derived isoflavones, are receiving great scrutiny as a food supplement for preventing hormone dependent disease such as postmenopausal osteoporosis. Their beneficial effects are derived from aglycone form of isoflavones, such as daidzein, genistein or glycitein. In contrast to the common usage of soybean, black bean (Rhynchosia Molubilis : Yak-kong) has been used as a supplement for preventing postmenopausal osteoporosis in oriental medicine. To investigate the effects of the saliva, artificial stomach fluid, and digestive enzymes on the conversion of glycosidic isoflavone to aglycone form, soybean and black bean were extracted with 70% methanol and freeze-dried. The recovery yield of methanol extracts of black bean was 14.1% which was higher than that of soybean, 13.5%. In terms of total isoflavones, we routinely obtained larger amount of isoflavones from black bean than those from soybean. By incubating methanol extracts of soybean and black bean with IN HCI for 180 min, the proportions of aglycones relative to the total isoflavone were significantly increased (32.4% and 52.4%, respectively). In vitro conversion, digestive enzymes ($\beta$-glucosidase and $\alpha$-glucosidase) may hydrolyze glycosidic bond of isoflavone more effectively than saliva or artificial stomach fluid did. It seems to say that the activity of $\beta$-glucosidase was higher than those of $\alpha$-glucosidase. The rate of conversion of glucoside form to aglycone form in black bean and soybean was low in physiological condition (pH) tested, although the enzymatic hydrolysis of glucoside was active. These results demonstrated that the composition of aglycone in food may be the important factors in terms of the bioavailability of isoflavones. (Korean J Nutrition 36(1): 32-39, 2003)

The purpose of this study was to investigate the changes of food habits and anxiety level of obese children on body weight control program. The body weight control program included nutrition education, psychotherapy and exercise for weekly session during 9 months. The results from this study were as follows. A total of 27 obese children(boys 44.4%, girls 55.6%) participated in this study. The average age of children was 11.7 years, average height and weight were 141.7cm and 48.1kg respectively. $R{\ddot{o}}hrer$ index(RI) of children was significantly decreased from 167 to 163(p<0.001) and BMI was significantly decreased from 24.5 to 23.9 (p<0.01) after body weight control program. This study also found obesity index(OI) was significantly decreased from 133% to 128%(p<0.01) of 18 children after program. There was not significant difference in food habits score but frequency of overeating, and eating frequency of meats were significantly decreased(p<0.05) after body weight control program. Also depression score significantly decreased after body weight control program(p<0.001) and there was significant negative correlation(r=-0.552) between food habits and anxiety level. The factors analysis of anxiety items indicated that children had feelings more calm and sate after program(p<0.05). Therefore continuous and practical nutritional education and psychotherapy to change food habits and anxiety level are necessary to decrease child obesity. These results suggest that body weight control program including nutrition education, exercise and psychotherapy may be effective physiological and psychological body health of obese children.

Purpose: The purpose of this study was to analyze the effectiveness of saline solution vs. heparinized-saline for maintenance of arterial lines and to detect changes in platelet and aPTT as physiological indexes. Methods: In this nonequivalent control group, non-synchronized, double-blind study the effects of heparinized and saline solution on the maintenance of arterial lines were compared. Fifty five patients received the heparinized solution and fifty nine patients received the saline solution. All patients who had surgery in K-university hospital between September and December 2011 were eligible for participation in the study. Results: There was no statistically significant difference between the saline and the heparin group in the maintenance time of the arterial lines or the number of irrigations. There was no statistically significant difference between the groups in changes in the number of platelets and aPTT for interaction between the groups and time intervals. Conclusion: The results indicate that saline solution can be used as an irrigation solution for the maintenance of arterial lines of adult surgical patients, rather than heparinized-saline, in view of potential risk factors in the use of heparin.

혈관신생은 모든 조직의 성장과 발달, 그리고 상처회복 등에 매우 중요하다. 지방조직은 우리 몸에서 가장 혈관이 발달된 조직으로서 각 지방세포들은 모세혈관에 둘러싸여 있으며 신생혈관들은 지방세포에 영양분과 산소를 공급한다. 혈관의 내피세포들은 파라크린 신호경로, 세포외 성분, 세포들 간의 직접적인 작용을 통해 지방세포와 교류한다. 활성화된 지방세포들은 VEGF, FGF-2, leptin, HGF와 같은 혈관신생인자들을 생성하며, 이들은 단독으로 혹은 협력하여 혈관신생을 증가시키고 지방조직의 성장과 대사를 촉진한다. 따라서 혈관신생 억제제들은 비만과 비만관련 질환을 치료하는데 유용할 것으로 생각된다.

In the oriental medicine, a mixture of herbs has been commonly used as important components to control allergic and inflammatory diseases. In the present study, we prepared a mixture of Dictamni Radicis Cortex(Baiksunpee), Houttuyniae Herba(Uhsungcho), and Aurantii Immaturus Fructus(Jisil) to examine its anti-allergic effects in activated mouse splenic cells and found that Mix-1 is involved in regulating levels of B cell activating factors (CD23 and CD11a), IL-1β, IL-6, IL-10, TNF-α, and 1gE as well as HRF expression. It was observed that Mix-1 did not have cytotoxic effects on mLFC. Mix-1 showed inhibition of CD23 and CD11 alpaha expression in mouse B cells, and also decreased the production of IL-6, TNF-α, and 1gE. Both RT-PCR and ELISA analyses indicated that IL-6 and TNF alpha production were regulated at the gene expression level. In contrast, IL-10 mRNA and protein levels were increased in activated B cells by Mix-1 treatment. We also found that Mix-1 inhibited B cell proliferation and inhibited histamine releasing factor(HRF) expression, suggesting its inhibitory effect on histamine secretion. These data indicated that Mix-1 has an anti-allergic effect in activated macrophages and further suggest the possible application of Mix-1 as a therapeutic agent for the treatment of allergy-related diseases.
