The main goal for the treatment of periodontal diseases is the regeneration of lost cementum, bone and connective tissue. Clinical and histological research suggests that it is possible to restore periodontal structures. Seeds of Carthamus tinctorius L. has been used for the treatment of bone fracture and osteoporosis in traditional Korean medicine. The purpose of this study is to examine the effect of extract of seeds of Carthamus tinctorius L. on mineralization in periodontal ligament cells and osteoblastic cells. Periodontal ligament cells were primarily obtained from a extracted premolars with non-periodontal diseases. Osteoblastic cells were obtained from calvariae of a fetal rat. Cells were cultured with DMEM at 37degrees C with 5% CO2 in 100% humidity incubator. Alkaline phosphatase(ALP) level and the number of calcification nodules were examined and western blot analysis using osteonectin was performed. Measurements of ALP levels and calcification nodules showed that extract of seeds of Carthamus tinctorius L. had significantly higher activity than control in all of both cells. In western blot analysis, protein expression of osteonectin indicated that extract of seeds of Carthamus tinctorius L. showed an increased pattern than control in all of both cells. From the above results, it seems that extract of seeds of Carthamus tinctorius L. has excellent effect on mineralization in periodontal ligament cells and osteoblastic cells.

PURPOSE: The aim of this study was to investigate attitudes toward death according to personality types and to suggest the need to develop related hospice programs. METHODS: Personality types were identified by the Korean version of the Myers-Briggs Type Indicator (MBTI) Form G. A questionnaire with 26 five-point Likert items was used to survey participants' attitudes toward death. RESULTS: The ESFP personality type was most common (20%) among available 100 participants. Significant differences were observed in the attitudes towards death preparation according to personality type s. Participants with personality preference types E, T and J showed positive attitudes (P<0.05) toward death, but no significant differences were shown based on the SN index. CONCLUSION: The attitudes toward death differed by personality types. Therefore, this study points to the need to develop diverse hospice programs based on the personality types.

A 62-year-old farmer was admitted to our department because of second degree chemical burns of both buttocks ten days following accidental contact with Gramoxone, a weed killer. He was treated with oral antibiotics and cold compresses and discharged after the burned area were reepithelialized. Laboratory findings were within normal limits for three weeks. Although lung fibrosis, hepatic and renal failure can be caused by repeated absorption of paraquat (Gramoxone) through injuried skin, systemic absorption through normal skin has not been reported. During the four month follow up period there were no systemic problems nor recurrence of skin lesions. We report herein a case of chemical burns induced by Gramoxone, which is probably an occupational dermatosis of farmers handling weed killers.

In Korea, there are four types of snakes, Glyoidius brevicaudus, G. intermedius (formerly named, saxatilis), G. ussuriensis, Rhabdophis tigrinus. The case-fatality rate in snake bite envenomation is very low. Snake venom is a heterogeneous mixture of pharmacologically active enzymatic, non-enzymatic protein, peptide toxins, other organic and inorganic substances. The pathophysiology evokes a complex series of events that depend on the combined and synergistic action of toxic and non-toxic components. The manifestation includes local and systemic effects. Local tissue effects includes of tissue pain, redness, swelling, tenderness, bullae formation, and necrosis. The major systemic manifestations of snake bite include neurotoxicity, myotoxicity, cytotoxicity, hemolytic, procoagulant, hemorrhagic, and hypotensive effects and interfere in platelet function. General care includes parenteral analgesia, antivenom administration, and serial assessments of limb swelling and laboratory tests. Despite the presence of soft tissue inflammation, prophylactic antibiotics are rarely required, and most patients achieve good outcomes with supportive care and antivenom alone. In the case of mild poisoning do not need to be treated with antivenom. In moderate to severe envenomation, antivenom should be administered. When administered antivenom, adverse reactions are monitored closely and treated early with epinephrine and anti-histamine. In future, we should establish algorithm provides guidance about clinical and laboratory observations, indications for and dosing of antivenom, adjunctive therapies, post-stabilization care, and management of complications from envenomation and therapy.

BACKGROUND: The in-hospital 'Utstein style' is international recommended guidelines for reporting outcome data from in-hospital resuscitation events. This study was designed to evaluate the current status of in-hospital cardiopulmonary resuscitation(CPR), and to provide basic data far the unified reporting guideline of resuscitation in Korea. METHODS: The patients who had received CPR in a university hospital were searched during one year period from March 1997. The variables according to the Utstein style were evaluated with review of the medical records. RESULTS: During the period, 428 patients had received CPR. Excluding the patients of out-of-hospital arrest and less than 8 years, 242 were enrolled. Their initial ECG rhythms were 55 of asystole, 148 of pulseless electrical activity, and 39 of ventricular fibrillation, The spontaneous circulation was returned in 118(49%, and 48(20% were maintained more than 24 hours. Twenty-two patients(9%) were discharged with spontaneous respiration. Among the survivors, 17 had the Cerebral Performance Category of 1. CONCLUSION: We recommend the Utstein style to report the outcome of in-hospital CPR.

PURPOSE: Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament(ACL) injury in MR image. MATERIAL AND METHODS: The knee MR images of 47 patients with ACL injury(complete; 24, partial; 23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament(PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. RESULTS: The means( +/- 2standard errors) of anterior translocation were different significantly in statistical analysis(p<0.001, student t-test) between injury group(7.51 +/- 1.16mm) and normal group(-0.56 +/- 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically b. etween injury group(0.23 +/- 0.02) and normal group(0.17 +/- 0.01)(p<0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear(66%), thirteen lateral meniscus tear(28%), ten medial collateral ligament injury(28%), one PCL injury (2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients {43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients(19%) and avulsion fractures of anterior tibial spine in four patients(9%). CONCLUSION: The associated findings with ACL injury (anterior translocation, buckling of PCL, associated bone, ligament and meniscus injuries) are considered to be helpful in the diagnosis of ACL injury on Knee MR images, when the findings of anterior cruciate ligament itself are not confirmative.

PURPOSE: We use many electronic devices for treating patients in our emergency department. Several studies have reported an association between electromagnetic field exposure and risk of cancer and other diseases. Our purpose was to measure the intensity of power-frequency magnetic fields in the emergency department and evaluate the conditions exceeded regulation guidelines for power-frequency magnetic fields. METHODS: Extremely low frequency magnetic fields were measured at 78 ordinary working spots in our tertiary hospital's emergency department (ED) and evaluated according to national regulatory guidelines and SWEDAC. Each spot was measured four times. During measurement, every electrical device in the emergency department was turned on. RESULTS: The average intensity of the magnetic fields in our emergency department was 0.99+/-1.27 mG. The maximum intensity was 8.3 mG, which was found in the pediatric section. CONCLUSION: The power-frequency magnetic field intensities of the various sections of our ED did not exceed national regulatory guidelines. However, pediatric and the minor emergency section showed magnetic fields intensities far above 2 mG. We found these high values outside the pediatric and waiting sections, where the electrical cabinet panel was located. We conclude that the electrical cabinet panel should be shielded and that similar studies are needed for other emergency departments.

Journal of the Korean Society of Traumatology 2011;24(2):129-135
PURPOSE: During August 2010, a natural gas fuel cylinder on a bus exploded in downtown Seoul, injuring 20 citizens. This kind of blast injury has never been reported in Korea before. Thus, the goal of this study was to review the clinical features of these victims to help physicians manage similar cases and to understand the risk factors associated with blast injuries in everyday life. METHODS: Twenty (20) victims who visited nearby emergency departments, and 3 peoples left hospital without care. Seventeen (17) victims were included in this study, and the following factors were investigated: age, sex, type of hospital, diagnosis of injury, injury mechanism, position of victim (in-bus/out of bus), classification of injury severity with START (simple triage and rapid treatment), and classification of injury according to the mechanism of the blast injury. RESULTS: The victims included 8 males (47%), 9 females (53%). The mean age was 37.5+/-12. Thirteen (13) victims were transferred to two tertiary hospitals, and 4 were transferred to two secondary hospitals. The types of injury were 3 fractures, 2 ligaments injuries, 6 contusions, 4 abrasions, and 3 open wounds (one of them was combined fracture). According to START classification, 17 victims were 1 immediate, 11 minor, 5 delayed, and no death. Classifications according to the mechanism of the blast injury were 1 primary injury, 6 secondary injuries (2 of them combined other mechanism), 3 tertiary injuries and 9 quaternary injuries. CONCLUSION: Trauma care physicians should be familiar with not only the specific types of injuries from blast accidents, but also the potential accidents that may occur in public facilities.
