Objective: Facial affect recognition is associated with neuropsychological status and psychiatric diseases. We hypothesized that facial affect recognition is associated with psychological status and perception of other affects. Methods: A total of 80 images depicting facial affect, including 20 Neutral, 20 Angry, 20 Fear, and 20 Sad, were screened for use in our research. A total of 100 healthy individuals were asked to rate these images using a 10-point Likert scale and complete psychological scales assessing the emotional statuses and cognitive functions. Results: The participants’ emotional state of aggression, attention, and impulsivity may have been associated with their interpretation of the Angry facial expressions. The participants often rated the Angry facial expressions as Fear. The participants rated Fear images as Angry or Sad. In response to a Sad facial expression, the participants reported psychological statuses of attention and impulsivity which were associated with the facial expression rating. The participants rated the Sad expression as Angry or Fear. Conclusion The psychological statuses of the participants were significantly correlated with their interpretation of facial affects. In particular, a psychological state of attention was often correlated with incorrect affect ratings. Attention and impulsivity could affect the rating of the sad facial expressions.

The mesenchymal chondrosarcoma of the orbit is so rare that only a few cases have been reported in Korea and world-wide. We experienced that a patient whose complaints were proptosis and diplopia caused by orbital tumor. After tumor removal, it was histologically diagnosed as mesenchymal chondrosarcoma. So we report a case of mesenchymal chonrosarcoma of the orbit with a review of the literature.

To delineate the coronary anatomy and left ventricular function during early myocardial infarction, coronary arteriography and left ventriculogrphy were performed, prospectively in 23(22%) of 105 patients who were admitted to the coronary care unit at Masan Koryo Hospital from June 1986 to June 1988 within 4 weeks after the onset of symptoms(medium:21 days, range:18 days to 25 days). 1) Among 23 patients, male is 20 patients and female is 3 patients. The ratio of male to female was 6.6:1. The mean age was 55.4+/-10.3 years(range:34-77 years). 2) Coronary artery narrowing state which related to myocardial infarction was as follows; 2 patients(7%) had normal, 1 patients(4%) had insignificant narrowing(below 50%) 5 patients(22%) had moderate narrowing(50-75%), 10 patients(43%) had severe narrowing(75-99%), 5 patients(22%) had complete occlusion(100%). 3) The range of coronary artery disease was as follows; 9 patients had one vessel disease, 10 patients had two vessel disease, 1 patients had three vessel disease, and ejection fraction had no significant difference among 3 groups but lowest in three vessel disease. Among 23 patients, 13 patients had anterior infarction, 10 patients had inferior infarction. 4) Left ventricular ejection fraction and multiple vessel disease had no significant difference between i) the young(under 45 years old) and the old(over 45 years old) age groups, ii) presence or non presence of previous angina, iii) Killip classification I, II and III, IV) anterior infarction and inferior infarction. 5) In left ventriculography, akinesis and dyskinesis were shown at similar ratio in anterior infarction and inferior infaraction. Dyskinesis was shown in 27% of patients who have 0-1 vessel disease, 50% of patients who have 2-3 vessel disease, 62% of patients who have collateral circulation, 26% of patients who dose not have collateral circulation. 6) Collateral circulation was found in 8 patients(35%). Age and left ventricular ejection fraction were high in patients without collateral circulation than with collateral circulation, but there is no significant difference and collateral circulation exists regardless of infarction site and range of coronary artery disease. 7) As for the complication of angiocardiography in this study, there was ventricular tachycardia in 3 patients(13%) without mortality. It is concluded that coronary arteriography can be safely performed in early stage after acute myocardial infarction. Also good prognosis is anticipated since three vessel disease and complete occlusion were low in acute myocardiaol infarction of Korean People. Since these are not much case performed study, however more study on this area is required.

The purpose of this study was to evaluate the effects of magnetic field on cellular activity of MC3T3-El cells. The celular activity was monitored by alkaline phosphatase and DNA synthetic activity in control, static magnetic field and pulsed electromagnetic field groups. A static magnetic field was applied to the cell by placing one, two, three, four, and five samarium-cobalt magnets above and below each cell plate for 24hours per day. A pulsed electromagnetic field with a frequency of 100 herz was applied for 10 hours per day. After 10 days of magnetic field exposure, there were increase of alkaline phosphatase activity in static magnetic field groups consisted of one, two and three magnetic groups, Alkaline phosphatase activities were not significantly increased in four and five magnetic groups, Application of pulsed electromagnetic field did not result in significant increase in alkaline phosphatase activity compared to control. DNA synthetic activity in both static and pulsed electromagnetic field group were not significantly different from that in control group, The result of this study suggest that magnetic field could have effect on the metabolism of bone cells related to the cellular metabolic process,

OBJECTIVES: Clinical symptoms and related psychological problems in children with attention deficit hyperactivity disorder (ADHD) are associated with low self-control and problematic interpersonal relationship between family members. A therapeutic narrative treatment based on "Treating Huckleberry Finn" by David Nylund was reported to be effective in reduction of individual or family conflicts. We hypothesized that therapeutic narrative treatment would improve self-control and parent-child relational problems. METHODS: Sixteen children who were diagnosed as ADHD participated in the current study. They were classified according to two groups, narrative treatment group and medication treatment group. The narrative treatment group (NTG) was asked to participate in 6 weeks combined therapy of medication and 11 sessions of narrative therapeutic treatment. The medication group (MG) was asked to participate in 6 weeks combined therapy of medication and education for behavior controls in ADHD children. RESULTS: During the 6-week treatment period, the clinical symptoms in NTG improved at a trend level, compared to MG [F(1,16)=4.32, p=0.054]. During the 6-week treatment period, the sub-scale of respecting for children in parent-child interaction scores [F(1,16)=8.65, p=0.010] and self-control scores [F(1.16)=3.78, p<0.01] in NTG improved significantly, compared to MG. CONCLUSION: Based on the current results, therapeutic narrative treatment can be a complementary trial for improving self-control and parent-child interaction in children with ADHD.

BACKGROUND: Coronary arterigraphy has been used as a tool to assess the degree of coronary artery narrowing and the result of balloon angioplasty, which frequently underestimates the degree of atherosclerosis. Intravascular ultrasound(IVUS) can give more delicate information about plaque morphology and the result of coronary intervention. We compared qualitaive and quantitative measurement between IVUS and coronary angiography after coronary intervention. METHODS: We used 30 or 20 MHz intravascular ultrasound catheter which was connected to Hewlett Packard Sonos 1500 Intravasscular equiment in 5 coronary balloon angiopasty and 3 Palmaz-Schatz stent implantation cases. Sites of intervention were at the left anterior descending coronary artery in 7 patients and at the left circumflex artery in one patient. Quantitative coronary angiography(QCA) was done by CAAS II system. We measured referenc diameter(RD), minimal lumen diamter(MLD), Lumen and vessel cross sectional areas(LCSA,VCSA) obstraction area(OA) and plaque area(PA) and also analysed plaque morphology. RESULTS: 1) IVUS is more sensitive in the detection of eccentricity, Calcification and dissection. 2) Before intervention, the mean reference diameter was 2.87+/-0.42mm,3.07+/-0.39mm,% diameter stenosis was 52.4+/-11.6%,65.3+/-9.22% and MLD was 1.32+/-0.24mm, 1.07+/-0.23mm in IVUS and QCA, respectively, which were no statistical significance between these parameters(p>0.05). After intervention, MLD and OA increased significantly(p<0.01) com pared with basal values but there were no significant difference between MLD and OA between 2 measurements(p>0.05). Plaque area measured by IVUS decreased from 9.84 to 7.26mm2 without statistical significance(p>0.05). 3) There was a good correlation in the measurement of the reference segments before intervention but this correlation was much lower after intervention in the reference and stenosis segments between 2 methods(r=0.8723 vs 0.6538, p<0.01). CONCLUSION: IVUS is considered as a sensitive tool in the detection of calcification, eccentricity and dissection and in evaluationg the results of the coronary intervention.

Excessive salt intake induces hypertension, but several gamma-aminobutyric acid (GABA) supplements have been shown to reduce blood pressure. GABAsalt, a fermented salt by L. brevis BJ20 containing GABA was prepared through the post-fermentation with refined salt and the fermented GABA extract. We evaluated the effect of GABA-salt on hypertension in a high salt, high cholesterol diet induced mouse model. We analyzed type 1 macrophage (M1) polarization, the expression of M1 related cytokines, GABA receptor expression, endothelial cell (EC) dysfunction, vascular smooth muscle cell (VSMC) proliferation, and medial thicknesses in mice model. GABA-salt attenuated diet-induced blood pressure increases, M1 polarization, and TNF-α and inducible nitric oxide synthase (NOS) levels in mouse aortas, and in salt treated macrophages in vitro. Furthermore, GABA-salt induced higher GABAB receptor and endothelial NOS (eNOS) and eNOS phosphorylation levels than those observed in salt treated ECs. In addition, GABA-salt attenuated EC dysfunction by decreasing the levels of adhesion molecules (E-selectin, Intercellular Adhesion Molecule-1 [ICAM-1], vascular cell adhesion molecule-1 [VCAM-1]) and of von Willebrand Factor and reduced EC death. GABA-salt also reduced diet-induced reductions in the levels of eNOS, phosphorylated eNOS, VSMC proliferation and medial thickening in mouse aortic tissues, and attenuated Endothelin-1 levels in salt treated VSMCs. In summary, GABA-salt reduced high salt, high cholesterol diet induced hypertension in our mouse model by reducing M1 polarization, EC dysfunction, and VSMC proliferation.

BACKGROUND: Lifestyle is an important risk factor for many diseases. We need to educate medical students for advocating health promoting behaviors to their patients. Teaching knowledge, however, was not enough for medical students to change their health-related lifestyle. In this study, we investigated health promoting behaviors of medical students, and the improvement of their health behaviors after competitive lifestyle modification program. METHODS: All sophomores of medical college in Seoul National University were included in this study. We performed lifestyle modification program consisting of lecture, group competition, and feedback. We focused on reforming health behaviors like smoking, drinking, exercise, stress management and eating habits. And we also checked common symptoms of functional diseases, medication frequency for relieving these symptoms and general life satisfaction. RESULTS: After 2 months of lifestyle modification program, the obese (P = 0.0455) and the average value of BMI (P < 0.001) were decreased and two of smokers quitted smoking. Numbers of medical students with health related habits such as regular exerciser (P = 0.027), frequent user of symptom-relief medication (P < 0.001), breakfast skipper (P = 0.005) were signifi cantly changed in positive way, and the average value of general life satisfaction score (P = 0.003) was improved. CONCLUSION: Lifestyle modification program improved medical students' health habits and enhanced general life satisfaction.
