Strain KK1 was isolated from soil contaminated with polycyclic aromatic hydrocarbons and able to mineralize anthracene, naphthalene, and phenanthrene. In this study, strain KK1 was tested to evaluate carbazole-degrading potential using radiorespirometry. When KK1 was pre-grown on phenanthrene the cells were able to mineralize carbazole much more rapidly, suggesting a possible close linkage between the pathways for catabolism of carbazole and phenanthrene. Such an increase in carbazole degradation was not appreciable when KK1 was pre-grown on naphthalene. Strain KK1 was identified as the genus Pseudomonas with over 90 % confidence based on BIOLOG system and FAME analysis. Analysis of PLFAs extracted from kk1 cells on carbazole medium revealed that lipids 10:0 3OH, 17:0 cyclo, and 18:0 were representatives produced or significantly increased in response to carbazole. Tests for antibiotics provided the data that strain KK1 was resistant to antibiotic ampicillin, but susceptibile to chloramphenicol, gentamycin, kanamycin, streptomycin, and tetracycline. Strain KK1 demonstrated strong resistance to most heavy metals such as Ba, Cd, Fe, Hg, Pb used in this study.

본 증례에서는 단일 치근을 가진 하악 제1유구치에 대해 서술하고자 한다. 5세 남아의 하악 제1유구치는 방사선 사진 검사결과 양측성으로 분명한 단일치근을 가진 것으로 나타났다. 보통 상악 구치는 3개의 치근을, 하악 구치는 2개의 치근을 가지나, 치아의 발육시기도중 Hertwig상피근초가 제 시기에 적절히 함입되지 못하면 치근이 서로 나뉘지 못하여 치근의 융합이 발생될 수 있다. 융합된 치근을 가진 구치는 정상적인 구치보다 불리한 치관-치근 비율을 가질 뿐 아니라, 여러 보고에 의하면 융합된 치근을 가진 사람은 다수 치아의 선천적 결손이나, 상악 전치에서 치내치가 발현될 확률이 높아 예방적 치과 치료가 필요할 수 있다. 그리고, 외배엽이형성증, 합지증, 만지증, 청색공막증과 같은 전신 질환과 연관되어 나타날 수도 있다고 한다. 치근융합은 유전적으로 상염색체 열성 유전을 따른다고 밝혀진 바 있다. 현재까지 단일 치근을 가진 구치는 대부분 영구 구치에서 많이 보고된 바 있지만, 유구치에서는 거의 보고된 바가 없기에 이에 보고하는 바이다. In this case, we would like to discuss about the single rooted deciduous mandibular first molar. The deciduous mandibular molar of a five years old boy was shown to have a single root, bilaterally. Ordinarily, the maxilary molars have three roots and the mandibular molars have two roots. However, when the hertwig's epithelial root sheath do not invaginate properly during tooth development, root fusion can occur from the absence of root separation. Molars with fused roots not only have unfavorable crown to root ratio, but also according to many reports, have higher probability of having multiple congenitally missing teeth or dens invaginatus in the maxillary incisors, consequently requiring preventive dental treatment. In addition, disorders such as ectodermal dysplasia, syndactyly, clinodactyly, bluish sclera can also be related to this condition. Root fusion is known to be of autosomal recessive inheritance. Up to date, single rooted molars have been reported several times in permanent dentitions but hardly in deciduous dentition, which is the motive for this paper.

Three analogs of ETH6024 were designed and synthesized as possible ionophores of carbonate ion considering the electronic effect of the para-substituents of the trifluoroacetophenone derivatives. In addition, the other three compounds were also designed and synthesized considering the entropic effect to form 1 : 1 complexes with carbonate ion. These syntheses were performed by N-alkylations of secondary amides followed by hydrolyses and trifluoroacetylbenzoylations.

This is a series of continuing research on facial bone fractures of Koreans worked by Dept. of Oral and Maxillofacial surgery, Dental College of Yonsei University, Seoul, Korea, since 1972. The study was based on a series of 630 patients with facial bone fractures treated as in patient at Yonsei Medical Center, Yonsei University, during the period of Jan. 1982 through Dec, 1987. The results obtained are as follows: 1. The ratio of Men to Women was 4.3 : 1, and admissions for facial bone fractures have been increased year after 1984. 2. The age frequency was highest in the third decade(38.3%). and fourth, second, fifth decade in orders. 3. The traffic accident was the most frequent cause of facial bone fractures(51.3%). 4. The most common location of facial bone fractures was the Mandible(35.3%), and Zygoma complex(29.8%), Nasal bone(15.0%), Maxilla(11.0%) were next in order of frequency. 5. In 291 patients of Mandible fractures, 226(77.7%) had fractures only in Mandible and 65(22.3%) had another facial bone fractures. The most frequent fracture site of mandible was the Symphysis(43.0%) and Angle(22.4%), and Simple fracture was the most frequent in type of fracture(66.9%). Intermaxillarty fixatin & Open reduction was major method of treatment(36.9%). 6. In 394 patients of Midface fractures 323(82.0%) had fractures only in Midface and 71(18.0%) had another facial bone fractures. The most frequent site of Midface fractures was zygoma complex & zygomatic arch(42.7%), and Simple fracture was the most common type of fractures. Observation(Maxilla :44.2%, Zygoma :51.0%) and Open Reduction(Maxilla :20.0%. Zygoma :23.5%) were the major method of treatment. 7. The frequency of Nasal bone fracture was about 1/5 of Midface fractures, and Closed Reduction(42.2%) was the major method of treatment. 8. The complication was reported in only 16 patients, and Malunion was the major complication. 9. Head(44.4%), Lower extrimities(14.5%) and Eye(12.3%) were injured commonly with facial bone fractures. 10. The elapsed time from injury to hospital was within 24 hours in 73.8% of patients, however 15.5% of patients arrived the hospital 72 hours after injury.

Background: From many previous studies, Pulmonary hypertension is the known independent predictive factor of the mortality in COPD. Also pulmonary hypertension is the major cardiovascular complication of COPD and is associated with the progression to cor pulmonale and poor prognosis. Author want to analyze the correlation between pulmonary hypertension and the severity of COPD which are classified by forced expiratory volume in one second, and the extent of progression to corpulmonale. Methods: Retrospectively we investigated the medical records of 118 patients with COPD who had pulmonary function test and echocardiogaphy more than one times during one-year follow-up (from June, 2005 to May, 2006) at respiratory division in chosun university hospital, and then 50 patients were enrolled in this study. We classified the severity from FEVl in pulmonary function test based on the GOLD guideline, also this was comparably analyzed with RVSP, RVIDd, Visual Grading from echocardiography. Results: 16 patients out of 50 were classified as moderate severity, 25 patients were severe, and 9 patients were very severe group. RVSP was higher in more severe groups than less severe groups but when it comes to pulmonary hypertension that RVSP is over 35 mmHg, there was no valid difference lies in those groups. As FEVl decreases RVSP and RVIDd increases, and observed relationship between RVSP which was classified as below 35 mm and above 35 mm groups and visual grading which was classified as normal and dilatated groups revealed valid correlation, Conclusion: As pulmonary function decreases, progression to pulmonary hypertension and cor pulmonale increases but there was no remarkable difference of prevalence in above moderate severity groups. 연구배경 폐고혈압은 이전의 많은 연구에서 만성폐쇄성폐질환에서 독립적인 사망의 예측인자로 알려져 있다. 또한 폐고혈압은 만성폐쇄성폐질환의 주요한 심혈관계 합병증이며, 폐성심으로의 진행 및 불량한 예후와도 관련되어 있다. 이에 저자는 폐고혈압과 1초간 노력성호기량으로 분류되는 만성폐쇄성폐질환의 중증도 및 폐성심으로의 진행 정도를 비교 분석하여 이들의 상관관계를 밝혀보고자 한다. 방법 2005년 6월부터 2006년 5월까지 1년 동안 본 병원 호흡기 내과에서 폐기능검사와 심장초음파 검사를 각각 1회 이상 시행한 적이 있는 118명에 한하여 의무기록을 후향적으로 조사하여 이 중에서 50명을 대상으로 하였다. 폐기능검사 시행 결과 얻은 1초간 노력성호기량을 바탕으로 GOLD guideline에 따라 중증도를 분류하였으며 이를 심초음파 시행 결과 얻은 우심실수축기압, 확장기말 우심실내부간격, 시각등급과 비교분석하였다. 결과 대상 환자 50명중 16명은 중등증, 25명은 중증, 9명은 최고중증 그룹으로 분류되었다. 우심실수축기압은 중증도가 높은 그룹에서 낮은 그룹에 비해 더 높게 나타났으나 폐고혈압에 해당하는 우심실수축기압이 35 mmHg이상인 환자에 있어사는 각 그룹간에 유의한 차이를 보이지 않았으며, 확장기말 우심실내부간격, 시각등급 또한 중증도와 유의한 차이를 보이지 안항ㅆ다. 1초간 노력성호기량이 감소함에 따라서는 우심실수축기압, 시각등급은 증가하였으며 우심실수축기압을 35mmHg 미만과 이상인 그룹으로, 시각등급을 정상과 확장이 있는 그룹으로 분류하여 비교한 결과에서는 유의한 상관관계를 나타냈다. 결론 폐기능이 감소할수록 페고혈압 및 폐성심으로의 진행이 증가하였으나 폐기능검사에서 중등도 이상의 그룹에서 유병률의 차이는 크지 않았다.

Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.
