The therapeutic properties of Ginseng have been known as popular Chinese midecine since time immemorial. It has been used in Korea, China, Tibet, Indonesia and India for thousands of years under various presentations, such as tes, tinctures, wines, pills, and unguents for the prevention of aging, tireness, headaches, amnesia, tuberculosis, diabetes, illness of the liver, heart, kidneys, nervous system etc. The main effective component of Ginseng has recently been considered to be saponins according to the chemical studies by Shibata's group and the pharmacological studies by Takagi et al., and also through the studies of Brekhman. The purpose of this study is to evaluate the response of topically applied Ginseng total saponin against inflammation. To induce the inflammation of skin the backs of 20 volunteers were treated with 10% sodium lauryl sulfate solution under occlusion for one hour. After removal of sodium lauryl sulfate. Gineseng total saponin ointment in various concentrations(2.5, 5, 10%) is topically applied under occlusion for 48 hours. Erythema on the areas treated with Ginseng total saponin ointment was significantly reduced than the control area. It is suggested that Ginseng total saponin has an anti-inflammatory effect on the inflammation of skin induced by sodium lauryl sulfate.

PURPOSE: A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS: Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, chi2 test was used and significant level (alpha) was set up as 0.05. RESULTS: Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION: Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.

A clinical trial was done to evaluate the antihypertensive efficacy and side effects of manidipine, a new calcium antagonist, in 30 patients with mild to moderate essential hypertension. 1) The study patients consisted of 19 men and 11 women, and the mean age was 51.8 years. 2) Blood pressure dropped significantly in 2 weeks and in 4 weeks, and well maintained throughout the study period. The mean-pressure drop was 26.2/14.9mmHg after 10 weeks. 3) Heart rate did not change significantly with manidipine therpy. 4) Optimal dose for effective pressure-drop was between 10 and 20 mg in 86% of patients. Overall good antihypertensive effect was achieved in 83% of patients. 5) All of the laboratory parameters including blood chemistry, glucose, lipid and electrolytes did not change, but serum calcium increased from 9.2% mg/dl (p=0.001) in 10 weeks. 6) Side effects were mild in nature(palpitation in 3, dry mouth in 1, weakness in 1 and impotence in 1 patient). In conclusion, manidipine monotherapy with 10 to 20 mg once a day regimen is effective and well tolerated in the patients with mild to moderate essential hypertension.

Since after first report of percutaneous transluminal coronary angioplasty in 1977, improved operator technique and advanced equipment designs have resulted in an increase in primary success rate from 67% to 92% in recent days. Despite these improvement, acute closure and restenosis remain as serious limitations to both the short and long-term success of PTCA. Coronary artery stents have been proposed as a method of treating acute closure and preventing restenosis. We implanted 21 balloon expandable Palmaz-Schatz Stent in selected 21 Patients(mean age 62+/-8 years, M/F : 16/5) with atherosclerotic coronary artery disease. The indications were elective stenting in 17, acute dissection postangioplasty in 2 and restenosis following angioplasty in 2. The clinical diagnosis of the subjects was unstable angina in 12 pts(57%), stable angina in 1, and post infarction angina in 8 including 6 acute myocardial infarction. The target vessel was right coronary artery In 12(57%), left anterior descending artery in 6(29%) and left circumflex in 3(14%). The size of implanted stent was 3mm in 15, 3.5mm in 5 and 4.0mm in 1. The morphology of attempted lesion was AHA/ACC classification type A in 1, type B in 17(B1 ; 1, B2 ; 16) and type C in 3. Angiographic findings were 1-vessel disease in 16 patients, 2-vessel disease in 4 and 3-vessel disease in 1. Coronary artery stenting wast technically successful in 21 all patients(100%) and complications included subacute total occlusion 1 week after stenting in 1, which was recanalized successfully by repeat PTCA without myocardial infarction, prolonged sinus arrest after stenting due to microembolism in 1 and puncture site bleeding requiring transfusion in 1. CONCLUSION: Coronary artery stenting was a safe and effective procedure to obtain adequate coronary blood flow in selected patients but long-term efficacy of primary elective coronary stenting should be evaluated prospectively.

Both idiopathic pulmonary fibrosis (IPF) and pulmonary involvement of collagen vascular disease(CVD) are well known cause of diffuse interstitial lung disease which lead to fibrosis and honeycombing. We analyzed HRCT findings of 33 patients with IPF and 14 patients with CVD in terms of predominant pattern, site of involvement, mediastinal lymph node enlargement, pleural change and pulmonary volume loss. Criteria of mediastinal lymph node enlargement and pleural thickening were 15mm in long diameter and 3mm, respectively. Volume loss of the lung was measured by using hilar height ratio (apex to hilum/hilum to diaphragmatic dome). Mean age was 61 years for IPF and 46 years for CVD and male: female ratio was 27:6, 4:10, respectively. Predominant HRCT pattern was honeycombing for IPF (63%), and ground-glass opacity for CVD (66%) (p=0.001). Predominantly, subpleural involvement was seen in 90% for IPF and 74% for CVD. Mediastinal lymph node enlargement was seen in 47% of the patient with IPF and 14% with CVD (p=0.004). pleural thickening was seen in 97% of the patients with IPF and 42% with CVD (P=0.002), Pleural effusion was seen in 10% of the patients with IPF and 36% with CVD (P=0.009). Hilar height ratio of more than 1.5 was seen in 84% of the patients with IPF and 29% with CVD. In conclusion, our study shows that patients with IPF are prone to have more progressed stage of pulmonary fibrosis than the patients with CVD on HRCT.

BACKGROUND: Large series of patients with symptomatic mitral stenosis have undergone percutaneous mitral balloon valvuloplasty(PMV) with use of the Inoue or double balloon technique. But to date the result of the two procedure have not been compared with a single series prospectively. METHODS: In order to assess the immediate hemodynamic results and the longterm efficacy of two different PMV technique, a prospective, randomized trial of PMV was performed using the Inoue balloon(Toray, I group) in 59 patients and the double balloons(a pair of Mansfield balloon. D group) in 61 patients with moderate to severe mitral stenosis. Before valvuloplasty, the patients series were comparable with regard to average age. gender, most clinical and echocardiographic variables. All the patients(120 patients, M/F 38/82, mean age 41+/-11 year) were preselected with good echoscore> or =9. RESULTS: The success rate was 83% in the I group and 89% in the D group when the success defined as mitral valve area(MVA)> or =1.5cm2 with 25% gain in MVA and mitral regurgitation> or =2+ at the end of procedure. The magnitude of increase of mitral valve area and decrease of mitral gradient, left atrial pressure and pulmonary arterial pressure were not significantly different in the Inoue and double balloon series(1.0+/-0.4 and 1.1+/-0.4cm2 for mitral vale area, 10.2+/-6.6 and 11.7+/-6.4mmHg for mitral gradient, 10.5+/-6,4 and 12.9 +/-7,3mmHg for left atrial pressure, and 8.7+/-7.3 and 10.1+/-9.4 mmHg for pulmonary artrial pressure respectively). Immediatly after dilation, the long diameter changes of the mitral orifice was more prominent in the D group(from 1.0+/-0.2 to 2.6+/-0.4cm p<0.01) than those in I series(from 1.1+/-0.4 to 2.3+/-0.3cm) Moreover, the magnitude of increase in the EF slop was significantly larger in the D group(31.9+/-17.0 vs 21.8+/-14.2mm/sec, p<0.001). The duration of total procedure(56+/-20 vs 84+/-24 min, p<0.002) and the fluoroscopic time (15+/-6 vs 25+/-11min, p<0.002) was significantly shorter in group I. The incidence of left to right shunt at the atrial level(Qp/Qs>1.5) was 3.4% in group I and 4.9% in group D. Severe mitral regurgitation> or =3+ occurred in 2 patients in each I(3.4%) and D(3.3%) group respectively. At follow-up, the mitral valve area was significantly decreased(1.6 in group I vs 1.8cm2 in group D, P<0.001 vs immediate after MVA) at 6 months and well maintained at 1 year follow-up in both groups. Until 6 months after valvuloplasty, the long diameter of orifice was greater in group D, however the difference was not apparent at 1 year follow-up. CONCLUSION: The Inoue and double balloon techniques obtained equivalent results of the success rate and the frequently of complications. However, the Inoue balloon technique reduced significantly fluoroscope time and total procedure duration. Double balloon technique afforded a longer longitudinal splitting of the commissure immediatly and 6 months after valvuloplasty. However the differences was not apparent at 1 year follow-up. Increased MVA was well maintained at 1 year in both groups. The severity of the newly developed mitral regurgitation immediately after valvuloplasty reduced significantly in 53% of the Inoue and 43% in the double balloon group at 6 months follow-up. In the view point of similiar immediate and late results of the two methods, the stepwise dilation with Doppler echocardiographic monitoring during the Inoue procedure appeared to be cumbersome.

BACKGROUND: The value of coronary reperfusion resulting from Thrombolysis and/or coronary angioplasty in patients with evolving myocardial infarction has been rigorously evaluated and improved left venticular function and short-term survival rates have been demonstrated consistently in controlled studies. Benefits from delayed coronary angioplasty at 7-10 days after onset of acute myocardial infarction (AMI) without thrombolysis remains unclear. In order to assess the effect of delayed reperfusion in infarct-related artery(IRA), we analyzed the restenosis rate of IRA after successful coronary angioplasty and the change of left ventricular function at late follow-up angiogram. METHOD: Coronary angioplasty in 69 lesions of 55 patients(M/F:48/7, mean age 53 years) with acute myocardial infarction(AMI) were performed at 7-10 days after onset of AMI and follow-up coronary angiogram (25 lesions of 20 pts) with left ventriculogram were obtained at means 5.1 months(range 4-6 months) after angioplasty. Restenosis rate of dilated infaret-related arteries and the changes of left ventricular function after angioplasty were evaluated. RESULTS: The overall procedural success rate of delayed elective coronary angioplasty in patients with AMI was 86% with a higher success rate in subtotally occluded vessel(98%) than in the occluded IRA(64%). Complications included acute closure after large dissection in 1(1.6%) and on -hospital mortality due to cardiogenic shock in 1(1.8%). Angiographically restenosis rate of IRA was 65% at mean 5.1 months follow-up, which was relatively higher than that after non-IRA angioplasty in AMI(25%) and in patients with angina(24%). Left ventricular ejection fraction improved significantly from 47.2+/-12.7% to 58.8+/-8.6%(P<0.05) at follow-up. Patients who had a patent IRA at follow-up had a restenotic IRA at follow-up had no statistically significant improvement in EF(table 3). Patients with a left anterior descending artery(LAD) lesion had lower mean immediate EFs than patients with right coronary artery lesion, however the degree of improvement in EF at follow-up was more significant in patients with LAD lesion. CONCLUSIONS: Delayed elective angioplasty of IRA at 7-10 days after onset of AMI was relatively safe and had comparable procedural success rate. Higher restenosis rate(65%) of IRA at follow-up appeared to be related, at least on part, to the endothelial dysfunction after ischemic-reperfusion injury and clinically unstable status. Left ventricular function improved significantly after angioplasty at follow-up. Recovery of left ventricular function might be reated to whether or not the IRA had an angiographically restenosis at follow-up.
