Purpose : This study evaluated the impact of the presence and aspect of mandibular third molars to the mandible angle fracture or condyle fractures in Korean. Materials and Methods : A retrospective study was designed for patients attending the division of Oral and Maxillofacial Surgery, Kang-dong sacred heart hospital for treatment of mandibular fracture from January 2006 to September 2010. The primary variable was the presence of mandibular third molar and the secondary variable was the aspects of third molar impaction. Mandibular third molars were classified by the impaction depth and the available space as Pell & Gregory system. Outcome variables were the presence of mandibular angle fracture or condyle fracture. Also the source of trauma, age, sex were studied. Hospital charts, radiographs were used for study. Statistic analysis was done with descriptive statistics, the X2-test, linear-by-linear association. P value under 0.05 was considered significant statistically. Results : The number of involved patients was 86. The ratio of male to female patients was about 9:1 for angle fracture and 7:3 for condyle fracture. The most common source of trauma was assault for angle fracture and fall down for condyle fracture. The presence of mandibular third molar increased frequency of angle fracture and decreased condyle fracture with larger impaction depth. But available space of mandibular third molar did not show high association with angle or condyle fractures. Conclusion: Preventive extraction of mandibular third molar is recommended for patients with high risk of angle fracture. Male patients at their third decade or martial artists, police officer could be the case. But it is not recommended for patients with low risk of angle fracture and high risk of condyle fracture relatively. Elder female patients without any symptom on their third molar could be the case.

Purpose: Reconstructive surgeries for equinocavovarus foot deformities are quite variable, including hind-midfoot osteotomy or arthrodesis, soft tissue procedure, tendon transfers, etc. Comprehensive evaluation of the deformity and its etiology is mandatory for achievement of successful deformity correction. Few studies in this field have been reported. We report on the clinical and radiographic outcome of reconstruction for cavovarus foot deformities. Materials and Methods: The study is based on 16 feet with cavovarus foot deformities that underwent bony and soft tissue reconstructive surgery from 2004 to 2008. We evaluated the etiologies, varieties of surgical procedures performed, pain score, functional scores, and patient satisfaction and measured the radiographic parameters. Results: The average age at the time of surgery was 39.4 years old, with a male/female ratio of 9/4 and an average follow-up period of 23.9 months (range, 12~49 months). The etiologies of the cavovarus deformity were idiopathic 7 feet, residual poliomyelitis 5 feet, Charcot-Marie-Tooth disease 2 feet, and Guillain-Barre syndrome and hemiplegia due to cerebrovascular accident sequela 1 foot each. Lateral sliding calcaneal osteotomies were performed in 12 feet (75%), followed by Achilles tendon lengthening and plantar fascia release in 11 feet (69%), and first metatarsal dorsiflexion osteotomy/arthrodesis and tendon transfer in 10 feet (63%). Visual analogue scale pain score showed improvement, from an average of 4.2 to 0.5 points. American Orthopaedic Foot and Ankle Society ankle-hindfoot score showed significant improvement, from 47.8 to 90.0 points (p<0.05). All patients were satisfied. Ankle range of motion improved from $27.5^{\circ}$ to $46.7^{\circ}$. In radiographic measurements, calcaneal pitch angle improved from $19.1^{\circ}$ to $15.8^{\circ}$, Meary angle from $13.0^{\circ}$ to $9.3^{\circ}$, Hibb's angle from $44.3^{\circ}$ to $37.0^{\circ}$, and tibio-calcaneal axis angle from varus $17.5^{\circ}$ to varus $1.5^{\circ}$ Conclusion: We achieved successful correction of cavovarus foot deformities by performing appropriate comprehensive reconstructive procedures with improved functional, radiographic measures and high patient satisfaction.

Cystic lesion of the jaw are frequently encountered clinically. Although they rarely lead to development of tumors, they can result in resorption of the jaw bone or asymmetry of the face may occur. The purpose of this study is to find the clinical and histopathological pattern of cysts and to help better understanding for the diagnosis and treatment of jaw cysts. The hospital chart, out-patient chart, panorama X-ray, histopathological report and operation report of 246 patients were reviewed who had been diagnosed as cyst. Sex distribution, age distribution, classification, anatomic distribution, clinical sign & symptoms, treatment, post-operation complications, recurrence rate were studied. Then significant difference between the diameter of cyst with bone graft and none-bone graft was calculated with SAS program. The results were as follows. 1. Among the total patient of 246 cases, male were 163 case(67.0%), and female were 83 case(37.0%), male predominated by the ratio of 1.98. 2. By age group, the 20's accounted for the largest proportion of the cases(27.2%) and the 30' accounted for the 2nd largest proportion of the case(19.5%). 3. Radicular cyst and dentigerous cyst were most common cysts, irrespective of 166 case(67.5%) and 62 case(25.2%). 4. Clinical sign & symptoms were swelling(167case), pain(85case), pus discharge(53case), teeth discoloration(28case), indicating that most complaints were related to inflammation and facial asymmetry. 4.9% of the total cases were discovered accidentally. 5. The primary site of cysts were maxillary anterior area(43.9%), the others were, in descending order, mandibular posterior area(25.6%), maxillary posterior area(14.6%). 6. Enucleation with endodontic treatment was a main treatment method(133 case, 54.1%) and 38 cases(15.4%) were enucleation with extraction, and 37 cases(15.0%) were only enucleation, and 21 cases(8.5%) were enucleation with bone graft. 7. The average diameter of cysts with bone graft was significally greater than with non-bone graft(p<0.05). 8. Post-operation complications occurred in 10 case(4.1%), all of this were due to secondary infection.

여주(Momordica charantia)의 과실 이외의 새로운 부위에 대한 이용 가능성을 구명하고자 과실 수확 종료기 무렵의 식물체부위별 charantin 함량을 분석하였다. 그 결과 두 품종 모두 잎의 charantin 함량이 $131.4-138.0mg{\cdot}g^{-1}D.W.$으로 가장 높았고 과실은 $14.7-16.0mg{\cdot}g^{-1}D.W.$으로 가장 낮아 수확기 무렵에는 charantin 함량이 과실보다 잎이 약 8배 이상 높은 것으로 나타났다. 또한 어린 암꽃, 수꽃과 줄기의 함량도 과실보다 많은 것으로 나타났다. 수확기 무렵의 식물체 부위별 charantin 함량의 비율은 과실이 5%로 매우 낮았으며 줄기 12-13%, 수꽃 14%, 암꽃 20-21%, 잎이 48% 정도로 가장 높았다. 착과 후 14일에 채취한 과실의 수확시기별 charantin 함량은 6월부터 7월 중순까지 수확한 과실의 charantin 함량이 $20.2-23.3mg{\cdot}g^{-1}D.W.$으로 높았고, 7월 하순부터 8월 하순까지 수확한 과실은 $13.3-19.4mg{\cdot}g^{-1}D.W.$으로 낮았다. 따라서 charantin 함량이 높은 과실을 수확하기 위해서는 온도가 높고 과실 비대속도가 빠른 7월 중순 이전이 좋을 것으로 사료되었고, 여주 과실 수확 종료기에는 과실 내 charantin 함량보다 여주의 잎, 암꽃, 수꽃 및 줄기의 charantin 함량이 높기 때문에 버리지 말고 새로운 가공품 개발에 이용하면 좋을 것으로 사료되었다.

This study was undertaken to investigate the effects of Gyoaesamultang in pregnant rats and their fetuses. Female Sprague-Dawley rats were orally administered with the Gyoaesamultang at dose of 5mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately, live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weight of Gyoaesamultang treated group has a tendency to increase compared to that of control group. There were no significant difference in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and implantation rate, delivery rate, late resorption rate and sex ratio. But Gyoaesamultang administered group showed lower early resorption rate than the control group. Neonatal body weight and number of fetus of Gyoaesamultang group were increased to that of control group. The fetuses of dams treated with Gyoaesamultang didn't showed external malformation. Vertebral and sternal variations were observed in Gyoaesamultang group but, compared to the control, those variations were insignificant. The number of ribs, cervical, thoracic, and lumber were normal. The number of sacral and caudal vertebrae were increased. Fetuses treated with Gyoaesamultang showed significant difference in the number of caudal vertebra(P<0.01). From these results, it can be concluded that Gyoaesamultang showed no toxicity effects on maternal body weight, early resorption rate, and number of live fetuses. There were no significant changes in organ weight, hematological data, reproductive organs. Although skeletal variations were showed in vertebrate and sternum, Gyoaesamultang were shown insignificant changes in bone malformation.

참조기에 $14\%$ 정도 천일염을 가해 저열건조기를 가공한 후 근육만을 $-20^{\circ}C$에서 냉동저장 하면서 영양 및 화학적 조성의 변화를 살펴보았다. 저염검 조기의 수분, 단백질, 지방, 회분은 각각 $74.6\%,\;18\%,\;3.4\%$ 및 $2.3\%$로 냉동 저장 중 큰 변화는 없었고, 유리아미노산의 경우는 저장 중 약 2배 정도 증가 하였으며 주요 유리아미노산으로는 glutamic arid, alanine, lysine, glycine이었다. 근육에서 추출한 중성지방질의 주요 구성지방산은 palmitic acid, stearic acid, palmitoleic acid, docosahexaenoic acid 이었으며 인지질의 주요 구성지방산은 docosahexaenoic acid, palmitic acid, eicosapentaenoic acid 이었다. 유리지방산 함량 및 산값은 가공직후 각각 $3.8{\mu}M/g,\;0.25mg/100g$에서 냉동 10개월 후에는 $7{\mu}M/g$과 0.4mg/100g로 약간의 증가 후세를 보였고, TBA값은 $20{\mu}M/kg$에서 저장 2개월째 $60{\mu}M/kg$으로 증가하였으며, 그 후 완만한 증가를 보였다. 산도 및 pH는 냉동 저장 중 거의 변화가 없었으며, 아미노태질소는 가공직후 90mg/100g에서 자장 10개월째에는 18mg/100g으로 약간의 증가 추세를 보였다. VBN은 초기 18mg/100g에서 저장 5개월째에 초기 부패 단계까지 증가하였으며, 이후 계속 증가하는 경향을 나타내므로, 저염건 조기를 $-20^{\circ}C$ 냉동저장할 경우, 5개월 정도 저장 가능할 것으로 생각되었다.

Purpose: The purpose of this study is to analyze the clinical prognostic factors which may affect the postoperative clinical results of the unstable ankle fractures. Materials and Methods: This study is based on 62 unstable ankle fractures treated by open reduction and internal fixation from May 1994 to June 2000, with a minimum follow-up period of 12 months(range: 13 months-7 years 3 months). The 62 patients were average 39.1 years old with male: female ratio of 41:21. Based on Lauge-Hansen classification, the supination-external rotation type was the most common with 36 (58.1%) cases. The clinical results was assessed by American Orthopaedic Foot and Ankle Society(AOFAS) functional scale. The sex, age, body weight, trauma-operation interval, operation time, cause of injury, fracture type were statistically analyzed as the possible postoperative clinical prognostic factors. Results: Postoperative AOFAS functional scale was average 82.1 points with 22(35.5 %) cases excellent, 12(19.4%) good. 16(25.8%) fair and 12(19.4%) cases poor results. The age and the operation time were found to be statistically significant factors affecting the prognosis(p<0.001). The sex, weight, trauma-operation interval factors did not significantly affect the clinical results. The pronation-external rotation type showed better clinical tendency among the fracture types, but without the statistical significance. Conclusion: The surgically treated unstable ankle fractures in patients whose age was above 41 years old or operation time exceeding 90 minutes showed significantly poor clinical results.
