It has been believed that the increased release of free oxygen radicals ($O_2^-,H_2O_2$, and $OH^-$) might be a factor in the pathogenesis of periodontal diseases. Antioxidant enzymes such as glutathione peroxidase(GSH-PX) and catalase can protect the tissue damage from the $H_2O_2$. In order to investigate the GSH-PX and catalase activity in the blood plasma and red blood cells(RBCs) of the patients with periodontitis, 19 patients who had good general health, attachment loss more than 6 mm and bone loss were selected as periodontitis group, 7 patients who had severely inflamed gingiva were selected as gingivitis group, and 15 volunteers with good general and periodontal health were selected as normal group. 17 of 26 patients were performed scaling and root planing to reduce the gingival inflammation for gingivitis and periodontitis groups, and were selected as posttreatment group. After blood plasma and RBCs were collected and separated 1 ml of peripheral blood from each subject, GSH-PX activity in blood plasma and RBCs was measured by the same method that Stefan et al. did, and catalase activity in RBCs was measured by the same method that Beers et al. did. The difference of GSH-PX and catalase activity between normal, gingivitis, and periodontitis groups was statistically analyzed by ANOVA with SPSS/PC+ program, and the difference between pretreatment and posttreatment groups was analyzed by Student t-test. The results were as follows : 1. GSH-PX activity in blood plasma was significantly lower in the gingivitis group($0.8683{\pm}0.0658$), periodontitis group($0.7130{\pm}0.1333$) than in the normal group($1.0241{\pm}0.0801$)(p<0.05), and GSH-PX activity in RBCs was significantly lower in the gingivitis groupt. $0.8156{\pm}0.1167$), periodontitis group($0.7533{\pm}0.1185$) than in the normal group($l.1963{\pm}0.2044$)(P<0.05), but there was no statistical significance in the difference of GSH-PX activity in RBCs between the gingivitis group and periodontitis group(p>0.05). 2. Catalase activity in RBCs was siginficantly lower in the periodontitis group($117.34{\pm}35.01$) than in the normal group($l52.38{\pm}32.09$)(p<0.05). 3. GSH-PX activity in blood plasma was significantly increased in the posttreatment groupe $1.0376{\pm}0.2820$) compared to the pretreatment group(0.7608 0.1600) (p<0.05), and GSH-PX activity in RBC was significantly increased in the posttreatment group($1.0421{\pm}0.2330$) compared to the pretreatment group($0.7728{\pm}0.1210$)(p<0.05). 4. There was no statistical significance in the difference of catalase activity in RBCs between the pretreatment group($112.04{\pm}43.65$) and posttreatment group($l33.41{\pm}39.16$)(p>0.05).The results, within the limits of the present experiment, suggest that the lowered activity of GSH-PX and catalase in blood plasma and RBCs may be related with periodontopathogenesis.

Glanzmann's thrombasthenia (GT) is a rare, autosomal recessive inherited congenital disorder, characterized by impaired blood coagulation due to platelet dysfunction. It was first reported by the pediatrician Glanzmann in 1918. GT affects both males and females, and it is more common in regions of the Middle East, India, and France, where intermarriage is common. It has an incidence of about 1 in 1,000,000 people. In South Korea, according to the Division of Rare Diseases, Korea Centers for Disease Control and Prevention, around 200 cases have been reported in 2018. Clinical symptoms include petechia, ecchymosis, epistaxis, and gingival bleeding. The spontaneous loss of deciduous teeth can result in excessive bleeding with that blood transfusion should be considered. Preventing hemorrhages and hemostasis are most important factors in dental treatment. Local bleeding can be controlled by compression, but platelet transfusion can be required by prolonged bleeding. Pediatric dentists can minimize the gingival bleeding by control of the oral hygiene to prevent gingivitis and dental caries. The importance of oral hygiene and periodic recall check-up should be emphasized. During dental treatment, the examination and the treatment plan of patient should be modified to prevention of hemorrhages carefully. A 6-year-old girl with GT was referred for the treatment of dental caries, and resin restoration was performed under nitrous oxide inhalation sedation. After treatment, compression was required for the bleeding control.

Purpose : Adiponectin is an endogenous modulator of vascular remodeling that suppresses vascular inflammation. However, the role of adiponectin in Kawasaki disease (KD) has not been elucidated. The purpose of this study is to investigate the correlation between serum adiponectin level and several parameters, such as interleukin (IL)-6, tumor necrosis factor $(TNF)-{\alpha}$, lipid profile, and C reactive protein (CRP), and to clarify the association between adiponectin and cardiac function. Methods : Twenty-two KD patients (22 patients in acute phase and 20 patients in subacute phase) were enrolled in the study group. The control group consisted of 31 subjects (13 febrile patients and 18 healthy children). Both groups underwent blood sampling and tissue Doppler imaging (TDI). Results : CRP was significantly increased in the KD group compared with the control group. There were no significant differences in serum $TNF-{\alpha}$, IL-6, and adiponectin levels between groups. However, a negative correlation was found between adiponectin level and CRP level or platelet count. Systolic myocardial velocity and A myocardial velocity measured by TDI were decreased significantly in the acute KD group compared with the subacute KD group and control group. Positive correlations were found between adiponectin level and systolic myocardial velocity or A myocardial velocity. Conclusion : In acute KD patients, low adiponectin level was related to severe inflammatory reactions and decreased left ventricular functions.

Intussusception is one of the most common cause of bowel obstruction in infant under the two years old, especially in male. Clinical analysis was enrolled on 54 intussusception cases who were diagnosed by ultrasound and treated by non-operative reduction at the Presbyterian Medical Center from June 2005 to May 2007. The results were as follow. 1) There was the most common(40.7%)between thirteen and twenty four months on the distribution of age. Male(72.2%) and female(27.8%) were in the ratio of 2.6:1 on the distribution of gender 2) The frequent symptoms were abdominal pain with grizzle(100.0%), vomiting(66.7%) and diarrhea(33.3%). There was a significant difference among them(p<0.05). There was the most common(46.3%) between 10,000/$mm^3$ and 15,000/$mm^3$ in the result of WBC. 3) 42.6% of patient at a private hospital performed primary care. The treatment after initiating the symptom of intussusception was performed between 6 hrs and 12hrs (37.0%). 4) The most common type and portion of intussusception were ileo-colon(98.1%) and hepatic flexure (68.5%). 5) 88.0% at air reduction and 86.2% at barium reduction were successful. The reduction rate were similar to both techniques. There was no significant difference between them(p>0.05).

Streptococcus pneumoniae is a common cause of acute otitis media, sinusitis, pneumonia, and the invasive bacterial infections in children. Rarely, S. pneumoniae is an uncommon cause of hemolytic-uremic syndrome (HUS). We report a 33 month-old girl who presented with pneumonia, and subsequently developed HUS. Her pulmonary infection was complicated by necrotizing pneumonia and acute respiratory distress syndrome. Cultures from blood and pleural fluid grew S. pneumoniae, serotype 19A. She was treated with antibiotics, dialysis and mechanical ventilatory support. She was discharged with normal renal function after 2 months of management. She remained healthy without renal complications at the 5 year follow-up visit.

We investigated the anti-obesity effects of Ishige okamurae extract (IOE) on body weight, epididymal adipose tissue weight, plasma lipid levels, and leptin levels in high-fat diet (HFD)-induced obese mice. After inducing obesity by feeding 45% HFD for 4 weeks, C57BL/6J mice were randomly assigned to HFD or HFD containing 5% IOE, and then fed for 6 weeks. The body weight and epididymal adipose tissue weight were increased by HFD, but they were significantly less in animals fed HFD containing 5% IOE than in those fed HFD. Levels of plasma triglyceride, total cholesterol, and LDL-cholesterol were significantly lower, but the HDL-cholesterol level was significantly higher in animals fed HFD containing 5% IOE compared with the HFD group. The plasma leptin level was significantly lower in animals fed HFD containing 5% IOE. The diet containing 5% IOE did not show any adverse effects on liver and kidney functions. These results suggest that IOE has a potential as anti-obesity agent by reducing body weight and lowering the levels of obesity-related factors in plasma.

Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation that is usually progressive. It is a major cause of morbidity and mortality worldwide, leading to substantial and increasing economic and social burden. Palliative care for COPD patients aims to reduce symptoms and exacerbations and improve exercise tolerance and quality of life. It is difficult to make a prognosis for COPD patients due to the variable illness trajectory and advanced care of patients. However, severity of breathlessness, assessment of lung function impairment, and frequency of exacerbations can help to identify palliative care needs and determine effective methods to mitigate symptoms, which is discussed in this paper. In these patients, it is recommended to provide individualized palliative care along with curative/restorative care at the onset of COPD symptoms. Before launching a palliative care system in Korea, it is necessary to prepare pulmonary rehabilitation resources, patient-centered communication, timely palliative responsiveness, and a program for effective advanced care planning. A multidisciplinary approach involving collaboration with not only the respiratory and palliative care teams but also primary care offers a new model of care for these patients and should be considered with a priority.

Tuberculous arthritis on the sternoclavicular joint is an uncommon disease and a delayed diagnosis can be due to the obscure clinical symptoms. We should suspect tuberculous arthritis in patients with slowly progressive pain, swelling, mild fever and a previous history of tuberculosis. Early diagnosis is important through conducting a thorough physical examination and performing laboratory tests and radiologic study. Tuberculous arthritis on the sternoclavicular joint should be treated with a combination of systemic antituberculous agents and thorough surgical debridement in marked damaged joints. When performing this operation, it is important not only to minimized the injury of the costoclavicular ligament, but also to avoid injury to the surrounding the vital structures such as the mediastinum and pleura after aggressive resection or radical debridement. We describe here 2 cases of the tuberculous arthritis on the sternoclavicular joint: one case had a good result after surgical debridement with using an anti-tuberculous agent, and the other had fatal complications such as mediastinal abscess and pleural effusion after the operation.

This is a result of clinical examination for workers working with Chromic acid and Chromium compounds in the plating room of their companies. I selected two companies that the plating process and the kinds of plating were similar. One (SW Co.) was more or less improved the operating environment with the ventilation machine so on and another (SR Co.) did not it so. The former was examined at March 29th 1977, the latter was at June 28th 1976. But the respiratory communicable diseases, flue or common cold so on were not spreaded there at that time. The clinical aspects were compared between the group of SW, and SR. The swelling and hyperemic signs of nasal mucous membrane and the experience of nasal bleeding were about 50%, generally, in all the groups. The following problem was dizziness or vertigo. The nasal signs in the group of SW (improved ventilation of the room air) were relatively weak, but in another, it was some what severe; - there was necrotic sign with thick nasal clast. They were only used of gauze mask when the vapors of various solvents were deeply full in the room. And there was very high rate of bronchial signs, sputum or coughing in the group of SW improved ventilation so called, than another one. I suppose that it means chronic inflammatory change of the bronchial mucous membrane with deeper signs, due to the individual protectors were carelessly or not used according to the improving of the operating environment. Theses nasal signs mentioned the above were not nearly in the other groups had not been done the Chromium plating. The Status of RBC, Hb and Ht, of urine protein and urobilinogen were mostly in normal range. But the number of WBC was more or less showed with a positive correlation to the working duration.

This study was performed to survey prevalence of Copper metabolism domain containing 1 (COMMD1) mutation using molecular diagnostic method in a population of Bedlington terriers in Korea. COMMD1 gene (formerly MURR1) functions as a regulator of sodium transport and copper metabolism. The deletion of exon 2 of the COMMD1 gene causes copper toxicosis in Bedlington terriers. Bedlington terriers with this autosomal recessive disorder were shown to have the elevated liver copper levels due to genetic derangement in the biliary copper excretion pathway. DNA samples were extracted from whole blood collected from 257 Bedlington terriers (109 males, 148 females) of pet dog clubs in Korea. A multiplex PCR was carried out to detect of exon 2 deletion of COMMD1 gene. In this study, it was possible to know the existence and prevalence of exon 2 deletion of COMMD1 in Bedlington terriers in Korea. Of the 257 samples, 131 (51%) were wild type homozygous for the normal COMMD1 gene, 108 (42%) were heterozygous, having both normal and mutated copy of the COMMD1 gene. The eighteen (7%) were mutant type homozygous. The results of genetic analysis could help establish proper management strategy and selective breeding program to prevent COMMD1 mutation in Bedlington terriers in Korea.
