The pediatric condylar fracture occurs very frequently in the mandible, but this injury is occasionally ignored due to difficulty of diagnosis and no cooperation of patient. The adequate initial diagnosis and active treatment must be performed because delayed and improper treatment lead to possible severe complication such as TMJ ankylosis and retardation of mandibular development. Most pediatric condylar fracture is mainly performed by the conservative or functional treatment. but it may be required open reduction according to cases. In this study, Activator is applied for functional treatment of pediatric condylar fracture and fair recovery of jaw function is acquired.

목적 : 관상동맥질환의 위험인자로서 혈청지질 및 혈장 지단백에 대한 관심이 높아지고 있고 또 아포지단백이 관상동맥 질환을 일으키는데 다른 지질보다 더 중요하다는 연구가 많이 발표되고 있으나 우리나라에서는 아포지단백에 대한 연구가 그리 많지 않은 편이다. 이에 저자등은 혈중지질치와 새로운 위험인자로 알려지고 있는 아포지단백치를 측정하고 이들과 관상동맥질환 중증도와의 상관 관계를 알아보았다. 대상 및 방법 : 관상동맥질환이 의심되어 관상동맥조영술을 실시한 69명의 환자를 대상으로 하였으며 12시간 이상 공복후 혈청을 채취하여 총콜레스테롤, 중성지방, HDL-콜레스테롤, 아포지단백 AI (ape AI), 아포지단백 B (ape B)를 측정하였다. 관상동맥조영상 50%이상의 협착이 있는 혈관의 수 (lesion number), 최대협착을 합한 값 (lesion score), 각 분절의 최대협착을 합한 값 (total score), 가장 심한 협착 값 (peak stenosis) 등으로 관상동맥 중증도를 알아본 다음 이들과 혈청지질치, 아포지단백과의 상관 관계를 비교해 보았다. 상관 관계는 Spearman's correlation coefficient를 구하였다. 결과 : 관상동맥질환의 중증도와 각 지질치 간의 상관 관계를 비교해 보았을때 lesion number와 관계있는 것은 연령 (r=0.2789), 중성지방치 (r=0.2829)이며 lesion score와 관계있는 것은 연령(r=0.2911), 중성지방치0 (r=0.3316), 총콜레스테롤과 HDL-콜레스테롤의 비 (r=0.2361), apo B 치(r=0.2759), apo AI과 apo B의 비 (-0.3154)로 나타났다. Total score는 연령 (r=0.3100), 총콜레스테롤치 (r=0.2452), 중성지방치 (r=0.3022), 총콜레스테롤과 HDL-콜레스테롤의 비 (r=0.2770), apo B치 (r=0.2927), apo AI과 apo B의 비 (r=-0.3408)와 연관이 있었고 peak stenosis는 중성지방 치(r=0.3305), ape B 치 (r=0.2968), apo AI과 apo B의 비 (r=-0.3977)와 관계가 있었다. 연령으로 조정하여 partial correlation을 좌면, 관상동맥조영술상 중증도는 중성지방치 (r=0.3408), apo B 치(r=0.2877), apo AI과 apo B의 비 (r=-0.3460)와 유의한 상관 관계가 있었다. 이중 ape AI과 ape B의 비는 lesion score (r=-0.2640), total score (r=-0.3057), peak stenosis (r=-0.3460)와 유의한 상관관계를 보였다. 결론 : 이상의 결과로 보아 apo B치 그리고 apo AI과 apo B의 비가 관상동맥 중증도의 예견인자로 다른 혈중 지질 치보다 더 유용하다는 것을 알 수 있었다. Objectives : Recently, it was reported that the measurements of apolipoprotein levels may be valuable in the clinical assessment of coronary artery disease severity. However there are a few reports regarding to the relationship between coronary artery disease severity and apolipoprotein levels in Korea. Thus, we measured serum lipid and apolipoprotein levels and studied the relationship between coronary artery disease severity and serum lipids and apolipoproteins levels. Subjects and Methods : The 69 patients who underwent coronary angiography to evaluate chest pain were subjected to this study. We measured the levels of serum cholesterol, triglycerides, HDL cholesterol, apolipoprotein AI(apo AI) and apolipoprotein B(Apo B) and measured the severity of coronary artery disease by lesion number, lesion score, total score and peak stenosis. Then, we studied the relationship between coronary artery disease severity and apolipoproteins and calculated the correlation coefficient. Results : The results were as follows. There are significant correlation(r=0.3) between age, triglycerides, apo B levels, apo AI/B ratio and coronary artery disease severity. In controlling for age, tyiglycerides, apo B levels and apo AI/B ratio shows significant correlation(r=0.3) with coronary artery disease severity. Especially, apo AI/B ratio shows significant correlation(r=0.3) with lesion number, total score and peak stenosis. Conclusion : These results suggest that the apo B levels and the ratio of apo AI/B can be used as significant independent predictor for coronary artery disease severity rather than other serum lipid levels.

Enamel matrix derivative(EMDOGAIN^(R))을 이용한 상악 소구치의 자가이식 치험례

오유향,김효식,정현구,조태식,위유민,이창섭 조선대학교 구강생물학연구소 2002 Oral Biology Research (Oral Biol Res) Vol.26 No.2

The success of tooth transplantation or replantation depends on the viability of periodontal ligament in the transplanted tooth. Mechanical injury to periodontal tissues frequently results in dental root resorption and ankylosis, which leads to the failure of transplantation or replantation. Enamel matrix derivative (EMD) has been recently used to induce periodontal regeneration. In this report, we show a clinical case of EMD application in the transplantation of an inversely impacted and immature tooth. An impacted second premolar was found in the right maxilla of a 14 year-old girl. The tooth was inversely impacted and the root formation was incomplete. When transplantation was carried out. EMD was applied to the periodontal tissues of the extracted premolar. The tooth was fixed at the correct position and the clinical condition was followed for evaluation for 3 months. Radiographs after 3 months exhibited new bone formation surrounding the transplanted tooth. There were no signs of root resorption or ankylosis, and reconstruction of the bone defect area at the maxilla was also found. Short-term results from this case indicated that EMD application was effective in the transplantation of an inversely impacted and immature tooth. In adddition, EMD might contribute to obtain good healing without ankylosis. Further follow-up observations are necessary to evaluate the regenerative effects of EMD.

뇌경색 환자에서의 혈장 지질과 항산화 영양소 상태에 관한 연구

최영선,이난희,서정규,박의현,조성희 경북대학교 병원 1998 경북대학교병원의학연구소논문집 Vol.2 No.1

뇌경색 환자의 생활 습관, 혈장 지질 및 적혈구 지질 및 적혈구 지질의 지방산 조성과 혈장 지질과산화물 농도, 항산화영양소인 비타민 E, A, β-carotene 상태를 측정하여 대조군의 자료화 비교함으로써 뇌경색 환자의 혈장 지질과 항산화영양소 상태를 조사하였다. 18명의 남자 환자군의 평균연령은 65.7(45~76)세였으며 36명의 건강한 남자대조군의 평균연령은 59.2(55~65)세였으며, 체중, 신장 및 BMI는 대조군과 환자군 간에 유의한 차이가 없었다. 환자군의 발병전 흡연 정도와 음주정도는 대조군보다 유의하게 높았으며, 적혈구지방산 조성에 있어서 포화지방산의 비가 유의하게 높았고 다불포화지방산의 비는 유의하게 낮았으며, 통계적인 유의성은 없으나 항산화 영양소 상태가 대조군에 비하여 불량하고 혈장 과산화지질의 종도가 높은 경향을 보였다. 이의 원인으로서는 환자군이 대조군에 비해 흡연율이 높고 음주량이 많으며 운동부족 등 부적합한 생활습관이 주요한 요인으로 작용한 것으로 판단되며, 따라서 바람직한 생활습관이 뇌경색질환의 예방에 기본요건이 된다고 사료된다. To investigate antioxidant and lipid staus of patients with cerebral infarction, 18 male patients admitted to Kyungpook National University Hospital from March to October, 1995 were compared to 36 healty male control subjects. The percentages of heavy smoking, heavy drinking and nonexercise before diagnosis of the disease in the patient group were significantly higher compared to the current status of the control group. Total cholesterol, LDL cholesterol and lipoprotein(a) were significantly higher in the patients than the control subjects. For the fatty acid composition of erythrocytes, total saturated fatty acids(% by weight) were significantly higher and total polyunsaturated fatty acids lower in the patient group than in the control group. Plasma levels of retinol, α-tocopherol and β-carotene were not significantly different between the patient group and the control group at the level of P<0.05 Alpha-tocopherol/total cholesterol of plasma was lower in the patient group with the statistical significance of P=0.054, and the plasma level of TBARS of the patient group was 1.98 nmol MDA/mL as compared to the level of the control, 1.60 nmol MDA/mL(P=0.066). Our results indicate that oxidative stress was increased in the patients with cerebral infraction, and such outcome might have resulted from undesirable life styles.

급성심근경색증의 조기진단에 있어서 Myoglobin의 진단적 의의

이정헌,김종근,정병천,서강석,박정배,조용근,류재근,전재은,채성철,박의현 大韓應急醫學會 1999 대한응급의학회지 Vol.10 No.2

Background: Exact and early diagnosis of acute myocardial infarction (AMI) is essential for the subsequent routine management of this frequent cardiovascular disease. Currently, AMI has been diagnosed using the combination of the history, electrocardiogram(ECG), and biochemical markers of myocardial necrosis. At present, many biochemical markers are used to diagnose AMI. In this study, the predictive values of serum myoglobin and creatine kinase-MB(CK-MB) were compared in the emergency department. Methods: Fifty-four consecutive patients who presented within 12 hours from onset of chest pain of presumed cardiac origin were enrolled into the study. Patients with trauma or renal failure were excluded. The serial serum myoglobin and CK-MB levels were obtained prospectively at admission and 2, 4, 6, 12, 24 and 48 hours after admission. We compare the levels of serum myoglobin and CK-MB within 2, 4, 6, 8, 10, 12, 24, and 48 hours after symptom onset respectively. And we compare the sensitivity, specificity, positive predictive value, and negative predictive value of myoglobin and CK-MB. Results: using World Health Organization criteria, 28 AMI patients were identified. Mean time from symptom onset to presentation was 4.1±1.3 hours. The predictive values of serum myoglobin were better than those of CK-MB within 6 hours after symptom onset. But, 6 hours after symptom onset, the predictive values of CK-MB were better than those of serum myoglobin. The false positive cases of serum myoglobin were 3-one was lung cancer with pleural effusion and the others were unstable angina. The false positive cases of CK-MB were 6-one case was viral myocarditis and the ohters were unstable angina. Conclusion: To compare the serum myoglobin and CK-MB in the diagnosis of AMI, serum myoglobin had better predictive values than CK-MB within 6 hours after symptom onset and useful in the early diagnosis of AMI. But, 6 hours after symptom onset, CK-MB had better predictive values than serum myoglobin and useful in following up.

Hur, Wee-Haeng,Park, Chan-Ho,Min, Gi-Sik,Hyun, Chang-Woo,Bae, Eun Hee,Lee, Jeong Hyun,Jung, Eun-Hee,Yoo, Jung-Sun,Suh, Min Hwan The National Institute of Biological Resources 2016 Journal of species research Vol.5 No.3

In 2012, the NIBR started publishing the Journal of Species Research (JSR) as an international specialized journal of biological taxonomy focusing on taxonomic research. JSR Volume 5 Number 3, to be published in October 2016, has been planned as a 'Special Edition on New and Unrecorded Species of Invertebrates in Korea', and so it consists of the reports of 149 new and unrecorded invertebrate species (including protozoa) discovered in Korea. In future, the JSR should further accelerate the use of such methods to generate valid data for new species and effectively support the compilation of 'National List of Species of Korea'. In this way, it will contribute significantly to enrich for biodiversity in Korea.
