From October 1991 to April 1996, 27 patients underwent aortocoronary bypass graft. There were 17 men, 10 women. The mean age was 65 years(range 45 to 76). The preoperative clinical status were chronic stable angina in 11 cases, unstable angina in 13 cases and postinfarction angina in 3 cases. The involved risk factors were as follows: Hypertension in 7 cases, Diabetes Mellitus in 5 cases and any other diseases in 3 cases. We divided these patients into two groups in this survey: The A group was 15 patients who were managed with cardioplegia from 1991 to 1994. The B group of 12 patients was done with intermittent aortic clamping without cardioplegia from 1995 to 1996. The mean numbers of graft per patient was 2.0 in A group and 2.83 in B group. The ischemic time per graft was 27.3 minute in A group and 18.5 minute in B group respectively. The morbidity was occlusion of grafted vessel in one patient and one of postoperative angina in A group. The total mortality was 14.8%(4/27), but mortality of B group was 8.3%(1/12).

BACKGROUND: Human herpesvirus 6 (HHV6), which was first discovered by Salahuddin in 1986, can be classified as HHV6 A and HHV6 B subgroups. It has been known that HHV6 B, which causes exanthem subitum, is related to the febrile illness of children while HHV6 A can be found in immunodeficiency patients. Over 90% of those who went through primary infection before two years of age show seropositive in adulthood. The virus can be detected in over 85% of the adult saliva. This suggests that the asymptomatic latent virus in normal adult saliva may be a source of primary infection by excretion. The objective of this study is to provide the basic seroepidemiology by finding the age of HHV6 primary infection and the extent of latent infection with classifying subgroups for healthy Korean children. METHODS: Healthy Korean children under the age of fifteen were classified into fifteen groups in total. Those groups under one year old age were divided into twelve groups with the interval of one month while those over one year old age were divided into three groups with the interval of five years. Thirty children were involved in each group, and sex ratio was almostly equal. The specific IgG antibody of HHV6 was evaluated by using an ELISA method. HHV6 DNA extracted from the saliva of the subject of fifty healthy children ranging from ages five to fifteen were detected and classified two subgroups by using a nested PCR. RESULTS: Statistically, the specific IgG antibody, which was highly maintained since neonatal age, became significantly decreased between 4 months and 6 months, and thereafter increased rapidly until it reached a peak for infants between 11 months and 12 months, and maintained a stationary high antibody level and high antibody positive rates (above 85%) until 15 years of age. The HHV6 DNA, detected in 18 (36%) out of 50 normal children between 5 and 15 years old, was totally confirmed as HHV6 B. CONCLUSION: Our data suggest that primary infection of HHV6 for Korean children may be occurred after 6 months age, and primary infection of HHV6 may be almostly happened before 1year age old. And HHV6 is excreted intermittently from the saliva of healthy children as in the case of adults. HHV6 B may be the major cause of HHV6 infection in healthy Korean children.

PURPOSE: The in vitro biocompatibility of Calcium Metaphosphate (CMP) with human bone marrow stromal cells (HBMSCs) and its effect on osteoblastic differentiation have been evaluated. MATERIALS AND METHODS: The effects of CMP on the HBMSCs undergoing osteoblastic differentiation were evaluated with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Morphologies of the HBMSCs were examined using scanning electron microscopy and confocal laser scanning microscopy. Osteoblastic differentiation of the HBMSCs was analyzed by alkaline phosphatase (ALP) staining and RTPCR. RESULTS: The CMP powder and disk did not exert cytotoxic effect on the HBMSCs. In addition, the HBMSCs were adhered on the surface of CMP disk as successfully as on the culture plate or HA disk and displayed similar actin arrangement and cellular phenotypes. Furthermore, the HBMSCs grown on three different matrices were able to support osteoblastic differentiation of the HBMSCs as accessed by ALP staining. However, the CMP disk compared to the HA disk has a better ability to induce expression of osteoblast-related genes such as ALP, osteopontin (OPN) and osteoprotegerin (OPG). CONCLUSION: The results demonstrate that, in addition to biocompatibility of the CMP with the HBMSCs, the CMP has an ability to stimulate osteoblastic differentiation of the HBMSCs in vitro.

BACKGROUND: Day surgery is increasing recently because of various benefits such as cost-saving, reduced emotional disturbance, and risk of infection. Children are ideal patients for day surgery. Developments in surgical, anesthetic technique, and pharmacology made day surgery to be increased without major complications. METHODS: This retrospective study includes our experience about outpatient anesthesia for pediatric general surgery in 219 children including both sexes up the age of 15 years over two years from jan. 1. 1994 to dec. 31. 1995. RESULTS: In 183 patients(83.5%), general anesthesia was done with mask inhalation. In 165 patients (75%), herniorrhaphy was done. Mean duration of operation, anesthesia and stay in recovery room were 25, 30 and 25 minutes respectively. There was no patient who needs admission and treatment due to complications. CONCLUSIONS: If we considered selection of patients, anesthetic techniques, and prevention and treatment of complications in day surgery, it is safe and desirable in modern anesthesia for us to do day surgery in pediatric outpatients.

BACKGROUND: Early diagnosis and treatment of hypertension is imperative to prevent the complications associated with this condition. The development of accurate and convenient methods of blood pressure measurement, therefore, is indispensible. At present, the JNC V has acknowledged the use of automatic sphygmomanometer that can be used without the help of someone else. We compared automatic oscillometric sphygmomanometers manufactured by Sein Electronics, korea(SE-7000 and SE-5000) with the standard Korotkoff auscultatory mercuy sphygmomanometer meter. The correlation between these two methods were calculated to determine whether these products could actually be used in clinical practice. This study was undertaken to ensure the clinical evaluation of these two products and standardization of an antomatic sphygmomanometer in korea before it is actually used. METHODS: The study included eighty-three patients, ranging in age from 14 to 81 years, who were admitted to Hanyang University Hospital in October, 1995. The blood pressure measured by the automatic oscillometric sphygmomanometer(SE-7000) in the right arm and was compared with that measured by the standard mercury sphygmomanometer(baumanometer) in the left arm. Also the blood pressure measured by the automatic oscillometric sphygmomanometer(SE-5000) at the wrist was compared by the baumanometer in the same side arm. The correlation between these methods were determined by the paired Student`s t-test and by the simple liner regression method. RESULTS: The p value of systolic blood pressure between two methods(SE-7000 and baumanometer) in the both arms was 0.896 and correlation coefficient was 0.8286. The p value of diastolic blood pressure between this two methods was 0.352 and correleation coefficient was 0.7455. The p value of systolic blood pressure between two methods(SE-5000 and baumanomter) by the arm and the wrist was 0.00018 and correlation coefficient was 0.8588, the p value of diastolic blood pressure between this two methods was 0.000048 and correlation coefficient was 0.5944. CONCLUSION: The blood pressure measured by the SE-5000 at the wrist was statistically different from that measured with the baumanometer in the arm. Further studies are necessary to use this product in clinical practice. However, the systolic and diastolic blood pressures measured with the SE-7000 in the arm were relatively similar to those measured by the baumanometer enabling this products to be effectively used in clinical practice.

OBJECTIVES: This retrospective study was performed to evaluate the clinical impact of diabetes mellitus on the prognosis in secondary space infection. MATERIALS AND METHODS: Medical records, radiographic images, computed tomography, and microbial studies of 51 patients (25 diabetic patients and 26 non-diabetic patients) were reviewed. Patients were diagnosed as secondary fascial space infections with odontogenic origin and underwent treatment at Chonnam National University Hospital, in Department of Oral and Maxillofacial Surgery, from January 2007 to February 2009. RESULTS: Compared to patients without diabetes, patients with diabetes were presented with the following characteristics: older age (diabetic patients: 62.9 years, non-diabetic patients, 47.8 years), more spaces involved (diabetic patients, 60%; non-diabetic patients, 27.3%), more intense treatment, longer hospitalization (diabetic patients, 28.9 days; non-diabetic patients, 15.4 days), higher white blood cell and C-reactive protein values, higher incidence of complication (diabetic patients, 40%; non-diabetic patients, 7.7%), and distinctive main causative microorganisms. CONCLUSION: These results suggest that the prognosis of diabetic patients is poorer than that of non-diabetic patients in secondary space infections since they had greater incidence rates of involved spaces, abnormal hematologic findings, more complications, and additional procedures, such as tracheostomy.

BACKGROUND: A recent case-control study from Finland reported a strong relationship between high antibody titers to Chlamydia pneumoniae , strain TWAR, and both chronic heart disease and acute myocardial infarction. Other studies also suggested an association between C. pneumoniae infection and coronary atherosclerosis, based on the demonstration of increased serologic titers and the detection of bacteria within atherosclerotic tissue, but this association has not been yet regarded as an established theory. The objective of this study was to investigate the relationship between C. pneumoniae immnoglobulin G antibody titers and angiographically diagnosed coronary artery disease. METHOD: Coronary angiography was performed. Controls (n=89) were coronary angiographically normal cases and coronary artery disease (n=115) was diagnosed if coronary artery luminal diameter is obstructed more than 50% in more than one coronary artery. Micro-IF assay was used to measure C. pneumoniae TWAR antibodies. The sera were titrated in two-fold dilutions starting from 1 in 8, and a titre of 1 in 8 or more was judjed positive. RESULTS: The estimated risk of coronary artery disease, adjusted for age and gender, was greater among subjects with high (> or =1:128) antibody titers than with low (< or =1:8) antibody titers (relative risk, 7.9:95% confidence interval, 1.3-47.9). CONCLUSION: These results support an association between infection with >ENGLISH=Ptimes-i< C. pneumoniae and coronary artery disease only in high (> or =1:128) antibody titers.
