The rate of longitudinal bone growth in the physeal plate is modulated by the size of pool of proliferative chondrocyte, the rate of cell division of proliferative chondrocyte. the height of terminal hypertrophic chondrocyte and matrix production in the transverse septa. The parameters such as growth plate thickness and the rate of cell division by proliferating chondrocytes have been indentified as useful indices of longitudinal bone growth rate. Recently the height and volume of hypertrophics have been reported to be one of the decisive factors in modulating the longitudinal growth rate. Fracture. osteotomy or limb lengthening have been known to affect the longitudinal growth rate and, it can be assumed. they could change the relationship betweengrowth rate andparameters. The purposes of this study were to clarify the relationship betweenparameters and longitudinal bone growth in osteotomized and lengthened limbs and t o compare the relationship between the different groups which showed changed growth rate affected by the amount of lengthening. Sixteen eight weeks old New Zealand white rabbitswere allocated into four groups; Group Ⅰ was osteotomized and stabilized by external fixater but without lengthening, Group Ⅱ was lengthened 20% of total tibia1 length at a rate of 0.8mm/day with external fixater. Group Ⅲ was lengthened 30% at a rate of 0.8mm/day and Group Ⅳ was lengthened 40% t o 50% a t a rate of 3. Pmm/day. Left tibia was used for that procedure and right tibia was left as a control. In the proximal & distalphyses of both tibia, following measure ments were performed. The longitudinal growth rates were determined by tetracychine labeling and indirect light fluoroscence microscopy. The physeal thickness was histomorphologically measured and the proliferative rate of chondrocytes in physeal plate was assessed by immunohistochemical staining using anti-bromcdeoxyuridine monoclonal antibody. The results obtained were as follows ; 1) The physeal thickness and the number of proliferating chondrocytes had linearcorrelation with longitudinal growth rate in the physis of the lengthened or osteotomized tibia of rabbits. ) The relationship of the physeal thickness and the number of proliferating chondro cytes with longitudinal growth rate had highercorrelation coefficiency and different slope of regression in the proximalphysis of lengthened or osteotomized tibia of rabbits compared to that in the distal physis of lengthenedorosteotomizedtibia ofrabbits. 3) The relative contribution of the physeal thickness orthe number of proliferating chondrocytes tothe longitudinal growth rates varied following the varied amount or rate oflengtheninginthe physis of lengthened orosteotomizedtibia of rabbits. As a conclusion, physeal thickness and the number of proliferating chondrocytes are considered to be significant parameters of longitudinal growth ratein the osteotomized orlengthened limb, but they may contribute to longitudinal growth rate differently according to the location, ageand local condition of the physis.

l-Muscone is synthesized for use as substitutive material of musk which is the active ingredient of woohwangchungsimwon. The objective of this investigation was to evaluate the acute and subacute toxicity of l-muscone in rats. In oral acute toxicity test, SPF Sprague-Dawley male and female rats were gavaged with l-muscone of two doses(0, 5.0g/㎏). No dead animal and abnormal autopsy findings were found in control and treated group. Body weights were slightly decreased in both sexes of rats treated with 5.0g/㎏. Therefore, oral LD_50 of l-muscone was consider to be higher than 5.0g/㎏ in male and female rats. In intraperitoneal acute toxicity test, rats were injected intraperitoneally with dosages of 0, 1,000, 1,316, 1,732, 2,279 and 3,000 ㎎/㎏. Decreased body weights and motor activities were observed at high dose group. Intraperitoneal LD_50 of l-muscone were 1,920 ㎎/㎏ in male and female rats. In the subacute study. l-muscone was administrated orally to both sexes of rats for 4 weeks as several doses(0, 10, 100 and 1,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data suggest that no observed adverse effect level of l-muscone in rats might be over 1,000 ㎎/㎏/day in this study.

The fungal sinusitis is relatively rare and mainly develops in immunocompromised hosts, but is sporadically appears in the immunocompetent patients, where its incidence tends to be increasing. Because the clinical features of this disease are similar to those of chronic suppurative sinusitis, this entity may be overlooked. We analysed thirteen fungal sinusitis from January 1997 through December 1999 based on clinical features, laboratory characteristics and operative findings. The results are as follows. 1)Fungal sinusitis occurred 3.3 times as frequently in female patients as in male patients and the peak age groups are 4th and 5th decades. 2) The time intervals between the onset of symptoms and the first hospital visit were as follows: 5 cases within 3 months, 1 case between 4 and 6 months, 3 cases between 7 and 12 months, and 4 cases over 1 year. 3) The chief complaints were nasal obstruction, postnasal drip, rhinorrhea, cheek pain, headache, ocular pain, sneezing. 4) The characteristic computerized tomographic findings were hyperattenuated lesions in the maxillary sinus and in the nasal cavity near the natural ostium. 5) The most common pathogen was Aspergillus(92.3%) 6) We performed Caldwell-Luc's operation only in 4 cases, Caldwell-Luc's operation with intranasal ethmoidectomy in 3 cases, Caldwell-Luc's operation with endoscopic sinus surgery in 3 cases and endoscopic sinus sugery only in 3 cases. 7) Most of the gross specimens revealed a fungus ball containing a black-brown necrotic debris or caseous material.

To investigate the effect of coffee consumption during pregnancy on serum lipids in maternal and infants' umbilical cord blood, 76 cases of newborn infants and women delivered of a child who had delivered at hospital located in Chung-Ju city from Feb. 1. 1996 to Aug. 31. 1996 were studied. The gestational ages of cases were 37 to 42 weeks and the average maternal ages were 28.3±4.63 years old without any other medical or obstetric problems. Infants' Apgar scores and birth weights were decreased by above 3 cups per day of coffee consumption during pregnancy. No relationships between coffee consumption during pregnancy and maternal serum lipid levels were observed. However, serum total cholesterol and LDL-cholesterol levels in infants' umbilical cord were significantly increased with increasing coffee consumption during pregnancy. In contrary to coffee consumption, alcohol drinking habits affected maternal serum lipid levels but not serum lipid levels in infants' umbilical cord blood. Coffee consumption during pregnancy increased caffeine concentration in infants' umbilical cord blood. These results suggest that caffeine from maternal consumption of coffee can easily pass to the fetus and significantly affect serum lipids levels in infants' umbilical cord blood rather than those in maternal blood.

연구목적 : 본 연구는 범법행위로 인해 검참에 구속된 청소년들의 6개월 이내 재범여부를 예측할 수 있는 요인을 분석함으로써 재범의 가능성이 높은 청소년들을 조기에 선별하여 적절한 중재를 시행하기 위한 목적으로 시행되었다. 방 법 : 검찰에 구속된 후 교도소나 소년원에 수감되지 않고 석박된 남자 청소년 125명을 대상으로 하였다. 범죄기록 검토를 통해 사회인구학적, 범죄관련 변인들에 대해 조사하였고, 가족환경 및 부모양육태도, 정신병리, 성격장애, 도덕발달수준 등과 연관된 변인을 알아보기 위해, 부모-이동 갈등해결척도(CTSPC), 한국판 가정환경척도(FES), 한국형 부모양육행동척도, 간이정신진단검사(SCL-90-R), Beck 우울증척도, Beck 불안 척도, 한국판 청소년용 도덕발달수준 평가도구와 한국판 성격장애검사(PDQ-R)를 시행하였다. 결 과 : 전체 연구대상 125명 중 55명 (44%)이 석방 후 6개월 이내에 1회 이상의 재범을 행하였다. 재범군은 비재범군에 비해 구속당시 나이가 어리고, 신체적 학대력이 높았으며, 도덕발달수준이 낮고, SCL-90-R의 적대감척도점수가 높으며 PDQ-R의 반사회적 인격장애에 해당되는 경우가 많았다. 두 집단간 가족환경이나 부모양육태도에는 유의한 차이가 나타나지 않았다. 재범군은 폭력범죄로 구속된 경우가 비재범군에 비해 적었고 첫 범죄시 연령이 어리고 전과가 있는 경우가 많았다. 로지스틱 회귀분석 결과, 재범에 대한 예측요인으로 첫 범죄당시 연령(오즈비=2.91), 반사회적 성격장애(오즈비=2.85), 신체적 학대력(오즈비=2.65)의 세 변인이 포함되었으며, 재범여부에 대한 판별력은 72.8%로 나타났다. 결 론 : 본 연구결과 구속된 청소년들의 재범률이 매우 높다는 사실과 범죄행위에 가담한 연령이 어릴수록, 반사회적 성격장애가 있고 성장과정 중 부모로부터 학대를 받은 경험이 있을수록 반복적인 범죄를 저지를 위험도가 높다는 것을 알 수 있었다. 향후 비행 청소년들의 재범을 예방하기 위해서는 이러한 특성을 가진 고위험군에 대한 조기개입 및 적응을 돕기 위한 프로그램의 개발이 중요할 것으로 사료된다. Objectives : This study was performed to investigate the factors predicting recidivism within 6months after release in arrested juvenile delinquents for proper screening and intervention of high-risk-subjects. Methods : The subjects consisted of 125 arrested male adolescents who were released after legal procedure in prosecutor office and court. The socio-demographic and crime-related characteristics. Were evaluated by police records, and the familial, psychopathology and personality characteristics, and the level of moral development measured by the Conflict Tactics Scale(CTS), Family Environment Scale(FES), Parental Behavioral Inventory, Symptom Checklist-90-Revised(SCL-90-R), Beck Depression Inventory, Beck Anxiety Inventory, Korean form of Moral Developmental Inventory for adolescents, and Personality Disorder Questionnaire-Revised(PDQ-R). Results : The recidivism rate within 6 months after release was 44% of the initial sample, Recidivists were younger and had higher scores on Anger-hostility scale of SCL-90-R and lower principle morality score than nonrecidivists. More recidivists had history of physical abuse and antisocial personality disorder on PDQ-R than nonrecidivists. They also showed the crime-related characteristics of lower percent of violence crime, higher incidence of previous conviction, younger age of the first crime. Among those variables, logistic regression showed that age of first crime, antisocial personality disorder, and history of physical abuse best predicted the recidivism within 6months after release. Conclusion : These results of present study suggest that the recidivism rate of arrested male adolescents is very high, and the age of first crime, antisocial personality disorder and history of physical abuse were key factors predicting recidivism. To prevent repeated crime of delinquent adolescents, the development of programs for those high-risk groups to help rehabilitation and adaptation in community would be essentil.
