Purpose: The National Health Insurance Service-National Sample Cohort and medical checkup data from 2002 to 2013 were used to evaluate the association between periodontal surgery for the treatment of periodontitis (PSTP) and vasculogenic erectile dysfunction (VED). Methods: Bivariate and multivariate logistic regression analyses were applied to a longitudinal retrospective database to assess the association between PSTP and VED while adjusting for the potential confounding effects of sociodemographic factors (age, household income, insurance status, health status, residence area, and smoking status) and comorbidities (diabetes mellitus, angina pectoris, cerebral infarction, and myocardial infarction). Results: Among the 7,148 PSTP within the 268,296 recruited subjects, the overall prevalence of VED in PSTP was 1.43% (n=102). The bivariate analysis showed that VED was significantly related to PSTP (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.38-2.06; P<0.001), and this was confirmed in the multivariate analysis after adjusting for sociodemographic factors and comorbidities (OR, 1.29; 95% CI, 1.06-1.58; P=0.002). Conclusions: Subjects with a history of periodontal flap surgery had a significantly higher risk of VED, after adjusting for potential confounding factors. Further studies are required to identify the key mechanisms underlying the association between severe periodontal disease and VED.

Objective : Salviae miltiorrhizae Radix (SMR) has widely used to treat patients with cardiovascular diseases such as coronary arteriosclerosis, angina pectoris and hyperlipidemia. This study was designed to investigate the effects of SMR on changes in serum cholesterol and protective effects on liver tissue damage in Hyperlipidemic rats. Methods : The present author investigated changes in serum glucose, cholesterols, AST/ALT and histopathological changes of liver tissue by oral administration of SMR in Rats. Results : In this study, body weights of hyperlipidemic rats induced high fat diet did not changed, and treatment with SMR did not affect body weights in hyperlipidemic rats. For experimental period, Food and Water uptake in SMR administered group were the same as those in hyperlipidemic control group. In this experiment, treatment with SMR decreased total cholesterol and AST in serum which elevated by high fat diet respectively. In addition, SMR administration protected liver tissue from damage induced by induction of hyperlipidemia. Conclusions: These results suggest that SMR is useful to treat patients with disease related to cardiovascular diseases including hyperlipidemia, because SMR can decrease cholesterol and AST in serum and also have non-specific protective effect on tissues including liver.

The purpose of this study was to investigate the association between dietary quality and the risk of coronary heart disease (CBD) among Korean men by a case-control study. Methods: The cases were 108 male patients with a first acute myocardial infarction or a new diagnosis of angina pectoris who were admitted to a university teaching hospital in Seoul. Controls were 142 age-matched patients admitted to the departments of ophthalmology and orthopedic surgery at the same hospital. Dietary information was assessed by a nutritionist using a semiquantitative food frequency questionnaire (FFQ), and dietary quality index (DQI) scores were calculated. Results: The intakes of total fat and cholesterol and body mass index (BMI) in cases were significantly higher than those in controls. The mean DQI scores were 8.6 for the cases and 9.4 for the controls. A higher DQI, which was indicative of a better quality diet, was inversely associated with the risk of CHD when comparing the highest to lowest quatiles, but borderline significant (odd ratios 0.60, 95% confidence interval 0.25-1.39, P for trend ＝ 0.05). Conclusions: Our findings suggest that better dietary quality may reduce the risk of CHD among Korean men.

Our study was carried out to analyze the variation factors of severity-adjusted length of stay(LOS) in coronary artery bypass graft(CABG). The subjects were 932 CABG inpatients of the Korean National Hospital Discharge In-depth Injury Survey from 2004 through 2008. The data were analyzed using $x^2$ test and the severity-adjusted model was developed using data mining technique. The results of the study were as follows: male(71.1%), older than 61 years of age(61.6%), more than 500 beds(92.8%) and admitting via ambulatory care(70.0%) appeared to have higher rate than otherwise. In-hospital mortality of CABG inpatients was 2.8%. In addition, 46.4% of the patients received their care in other residence. The angina pectoris(45.6%) was found to be the highest in principle diagnosis, followed by chronic ischemic heart disease(36.9%) and acute myocardial infarction(12.0%). We developed severity-adjusted LOS model using the variables such as gender, age and comorbidity. Comparison of adjusted values in predicted LOS revealed that there were significant variations in LOS by location of hospital, bed size, and whether patients received the care in their residences. The variations of LOS can be explained as the indirect indicator for quality variation of medical process. It is suggested that the severity-adjusted LOS model developed in this study should be utilized as a useful method for benchmarking in hospital and it is necessary that national standard clinical practice guideline should be developed.

Chest pain is classified into two major categories of cardiac chest pain and non-cardiac chest pain. Cardiac chest pain is caused by cardiovascular disease, for example, myocardial infarction, angina pectoris, valvular heart disease, cardiac enlargement or hypertrophy, dissecting aortic aneurysm, pericarditis, myocarditis, etc. When the chest pain is not attributed to heart disease, it is termed non-cardiac chest pain. Non-cardiac chest pain is caused by pulmonary, gastrointestinal, musculoskeletal disease, psychiatric factor, etc. In tills case, we treated a 54-year old female patient who was diagnosed with dilated cardiomyopathy and suspicious sick sinus syndrome. She complained of chest pain, exertional dyspnea, dizziness and headache. For treatment, we made use of Yugultangami(六鬱湯加味) and Daejobwan(大造丸). Before and after treatment, we measured Heart rate variability(HRV). In result, the clinical symptoms were improved and there was a significant increase in assessmeut by Heart rate variability(HRV). Tills result suggests that Yugultaugami aud Daejowhan have a good effect on cardiac chest pain.

Nifedipine, one of calcium channel antagonists, has been used for the treatment of mild to moderate hypertention, angina pectoris, Raynaud's phenomenon and various other cardiovascular diseases. Because of its short biological half-life, several sustained-release (SR) formulations of nifedipine have been developed. and used clinically. The bioequivalence of the two nifedipine SR preparations was evaluated according to the guidelines of KFDA. The test product was Hanmi Nifedipine SR $tablet^{(R)}$ made by Hanmi Pharm. Co. and the reference was Adalat Oros $tablet^{(R)}$ made by Bayer Korea. Thirty healthy male subjects were divided into two groups and a randomized $2\times2$ cross-over study was employed. After one SR tablet containing 33 mg of nifedipine was orally administered, blood sample was taken at predetermined time intervals and the concentrations of nifedipine in plasma were determined using a validated HPLC method with UV detector. Two pharmacokinetic parameters, $AUC_t\;and\;C_{max}$, were calculated and analyzed statistically for the evaluation of bioequivalence of the two products. Analysis of variance was carried out using logarithmically transformed parameter values. The $90\%$ confidence intewals of the $AUC_t\;and\;the\;C_{max}\;were\;log\;0.81\sim1og\;1.19\;and\;log\;0.84\sim\;log\;1.13,\;respectively.$ These values were within the acceptable bioequivalence intervals from log 0.8 to log 1.25 in KFDA guidelines. Thus, the criteria of the KFDA guidelines for the bioequivalence was satisfied, indicating that Hanmi Nifedipine SR tablet is bioequivalent to Adalat Oros tablet.

Bisoprolol, one of the $\beta_1-adrenorecepter$ antagonist, has been used for the treatment of mild to moderate essential hypertension anti stable angina pectoris. The oral bloavailability of bisoprolo1 is high $(90\%)$ and the drug has a long elimination half-life, $9{\sim}12\;hr$, which allows once-daily administration. The bioequivalence of two bisoprolol preparations was evaluated according to the guidelines of Korea Food & Drug Administration (KFDA). The test product was Concor $tablet^{(R)}$ made by Newgenpharm and the reference product was Monocor $tablet^{(R)}$ made by Wyeth Korea. Twenty healthy male subjects, 23.8 (21-30) years old and 03.8(52-92) kg, were randomly divided into two groups and a randomized $2\times2$ cross-over study was employed. After two tablets containing 10 mg bisoprolol hemifumarate were orally administered, blood was taken at predetermined time intervals and the concentration of bisoprolol in plasma was determined using an HPLC method with fluorescence detector. Two pharmacokinetic parameters, $AUC_t\;and\;C_{max}$ were calculated and analyzed statistical]y for the evaluation of bioequivalence of the two products. Analysis of variance was carried out using logarithmically transformed parameter values. The $90\%$ confidence intervals of $AUC_t\;and\;C_{max}$ were log $0.95{\sim}1og\;1.04\;and\;1og\;0.96{\sim}1og\;1.07,\;respectively.$ These values were within the acceptable bioequivalence intervals of log $0.8{\sim}log\;1.23$. Thus, the criteria of the KFDA guidelines for the bioequivalence was satisfied, indicating that Concor tablet is bioequivalent to Monocor tablet.

In controlling chronic intractable pains, the current therapeutic methods used are exercise, over the counter medication, cognitive-behavioral therapy, opioid medication, neural blockade, operation, etc., spinal cord stimulation being the last resort. Spinal cord stimulation was initiated when Shearly and others clinically tested the Gate control theory of Melzack and Wall. This had triggered the advancement of theoretic research on the mechanism and hardware necessary and has resulted in an accumulation of clinical experiences. This is known to be effective for treating sympathetic pain, arachnoiditis, failed back pain syndrome, radiculopathy, peripheral vascular disease, phantom limb syndrome, post-herpetic neuralgia, peripheral neuropathy, and angina pectoris. This report describes our experience in experimental spinal cord stimulation in patients with simultaneous post-herpetic neuralgia and herniated intervertebral disc. There wasn't any improvement in the post-herpetic neuralgia but the symptoms of a herniated intervertebral disc was much ameliorated. This was quite an unexpected result. The patient's back pain returned when the stimulation stopped.

Background: Although dental implantation has become widespread and acceptable treatment for dental prosthodontics, maxillary posterior jaw region is often complicated by the pneumatization of the maxillary sinus and physiological resorption of the alveolar bone. When this occurs, the residual bone between the floor of the sinus and the crestal ridge is inadequate for the placement of implants. The sinus elevation procedure provides a way to increase the amount of available bone and to allow the placement of longer implants. Materials & methods: We studied 11 patients requiring the implant placements and the maxillary sinus elevation simultaneously from 1996 to 2003 in our clinic. Nine patients were males and two patients were females, aged from 39 to 72(mean=51.6). Four patients had medical compromised states; angina pectoris, diabetes, hypertension, hepatitis. Patients didn't show any pathologic findings clinically or radiographically. We studied the success and survival rate of implants, factors increasing the osseointegrating capacity of implants. Results: The success rate of osseointegration of implants was 93%. At least 6 months after loading on implants, the survival rate of implants was 78.5%. Autogenous bone graft and adequate residual bone height(>6mm) increased survival rate of implants. Conclusion: Successful implant placement with maxillary sinus elevation mainly depends on sufficient residual bone height, healthy maxillary sinus, autogenous bone graft.
