Objective : Ssanggang-tang(SGT) is noted as an effective method to treat hyperlipidemia in China. The main purpose of this study was analysis of the effects of Ssanggang-tang(SGT) on rats induced with caused hyperlipidemia. Methods : We observed 3 experimental groups: normal, control, and SGT. Rats were provided a normal diet in the normal group, and the other groups were provided a hyperlipidemic diet to induce hyperlipidemia. After 2 weeks, SGT was treated in the SGT group. For 6 weeks, values related to hyperlipidemia were observed in the 3 experimental groups. Results : SGT decreased some values related to hyperlipidemia like total cholesterol, low density lipoprotein cholesterol(LDL cholesterol), triglyceride, acetocoenzyme A acetyltransferase(ACAT), and 3-hydroxy-3-methylglutaryl coenzyme A reductase(HMG-CoA reductase). However, it showed no effect on weight change or high density lipoprotein cholesterol(HDL cholesterol). Conclusion : These results suggest that SGT might be effective in treatment and prevention of hyperlipidemia.

이재휘,Lee, Jae Hwy 대한악안면성형재건외과학회 1991 Maxillofacial Plastic Reconstructive Surgery Vol.13 No.3

저자는 중앙 안면부 외상후 사골골절 및 협골 복합체 골절로 인한 골절편의 변위로 시신경이 손상되어 실명한 2명의 환자를 경험하였기에 문헌고찰과 함께 이에 보고하는 바이다. Ocular injuries often accompany midfacial trauma Blindness related to indirect optic nerve injury in midfacial fractures is an uncommon and usually permanent complication. Opic nerve blindness is secondary to an indirect optic nerve injury due to the skeletal distortion that occurs in a facial fracture and almost all are caused by frontal, nasoethmoido-frontal or Le Fort III type fractures. When the loss of vision following midfacial fractures is complete and immediate, the prognosis is poor in spite of treatment. Computed tomography revealed compressin of the optic nerve by bony fragments. And so if injury to the optic nerve is suspected, a CT-scan must be performed and massive steroid therapy must be started as soon as possible. Surgery must be performed if there are hematoma or bony fragments injuring the nerve. The following report concerns two patients who suffered immediate and total loss of vision due to a midfacial fracture with no improvement after massive steroid therapy and surgial decompression.

저자는 31세 여자환자의 좌측하악부에서 매복된 제3대구치 주위의 함치성 낭종에서 기원한 Group 3a type의 다방성의 낭종성 법랑아세포종을 경험하여 병소에 포함된 치아 발거슬 및 enucleation/curettage로 현재까지 재발없이 치유되었기에 병리조직학적 소견을 중심으로 문헌고찰과 함께 보고하는 바이다. Ameloblastoma is an aggressive but benign epithelial neoplasm of odontogenic origin, and the occurrence of odontogenic epithelium in the wall of a dentigerous cyst is well-known entity. The presence of ameloblastic proliferation in the walls of odontogenic cysts has been reported for many years. Cahn in 1933 described a case in which he considered an ameloblastoma to have originated in a dentigerous cyst, and numerous other cases of ameloblastomatous proliferation have since been reported. In 1977, Robinson and Martinez described a distinct variant of ameloblastoma in which the response to curettage was found to be favorable with a recurrence rate of 25%. The gross and microscopic features indicated that this variant vas associated with a large cystic cavity with either luminal or mural proliferation of ameloblastic tumor cells, and they referred to this variant as unicystic ameloblastoma. Unicystic ameloblastoma occurs most commonly in the second and third decades of life, which is considerably younger than the average age of discovery for the classical ameloblastoma. For the accurate histopathological diagnosis of the unicystic ameloblastoma, the specimen obtained the excisional biopsy, complete enucleation or incisional biopsy from the multiple site of the lesion. This article provides histopathologic evidence of multilocular unicystic ameloblastoma in which ameloblastic tissue was associated with a dentigerous cyst that was found in a 31-year-old female, and complete radiographic, photographic, and microscopic documentation is presented.

이재휘(Jae-hwi Lee),한재혁(Jaehyeok Han),이민욱(Min-wook Lee),최재문(Jae-mun Choi),백현우(Hyunwoo Baek),이상진(Sang-jin Lee) 한국정보보호학회 2017 정보보호학회논문지 Vol.27 No.1

프로텍터란 프로그램의 핵심 아이디어를 보호하기 위해 실행파일을 압축하고 난독화를 적용하는 프로그램이다. 그리고 최근 악성코드가 자신의 악성행위를 분석하기 어렵게 만들기 위해 프로텍터를 적용하고 있다. 프로텍터가 적용된 실행파일을 정밀분석하기 위해서는 프로텍터를 해제하는 언패킹 작업이 필요하다. 기존의 연구에서는 OEP를 찾아 언패킹을 하는 것에 주력하였지만, 분석방해가 목적인 프로텍터의 경우 실행압축 해제가 완료된 이후의 실행에 분석방해 기능들이 남아있게 되어 여전히 분석에 어려움이 있다. 본 논문에서는 분석방해가 목적인 Themida 프로텍터가 사용하는 분석방해 기술을 분석하고 그에 대한 대응방안을 제안한다. A protector is a software for protecting core technologies by using compression and encryption. Nowadays malwares use the protector to conceal the malicious code from the analysis. For detailed analysis of packed program, unpacking the protector is a necessary procedure. Lately, most studies focused on finding OEP to unpack the program. However, in this case, it would be difficult to analyze the program because of the limits to remove protecting functions by finding OEP. In this paper, we studied about the protecting functions in the Themida and propose an unpacking technique for it.

The calcifying odontogenic cyst was first recognized as a separate entity by Gorlin and his associates in 1962. It is a rare lesion and accounts for only about 2% of all odontogenic tumors and cysts. The majority of calcifying odontogenic cysts are cystic, although approximately 15% are solid lesions. Hence, WHO in 1971 classified calcifying odontogenic cyst as a benign odontogenic tumor. The calcifying odontogenic cyst often occurs in association with, or contains areas histologically similar to, a variety of odontogenic tumors, such as complex and compound odontomas, ameloblastoma, ameloblastic fibroma, ameloblastic fibro-odontoma, odonto-ameloblastoma, calcifying epithelial odontogenic tumor, and adenomatoid odontogenic tumor. Among these, odontoma is most often found in relation to the calcifying odontogenic cyst, although only a few reports of calcifying odontogenic cyst found concurrently with true odontoma have been pulished. This report presents a case of calcifying odontogenic cyst associated with odontoma, reviews the current knowledge concerning this lesion, and attempts to clarify certain ambiguous histologic features of the tumor.

골격성 제III급 부정교합자의 LE FORT I 상악골 절단술후 교합평면의 안정성에 관한 연구

이재휘(Jae Hwy Lee),이호준(Ho Jun Lee) 대한구강악안면외과학회 1996 대한구강악안면외과학회지 Vol.22 No.3

Surgical alteration of occlusal plane in patients with dentofacial deformities is necessary to establish optimal functional and esthetic relationships. In the stability of occlusal plane, clockwise rotation of the maxillomandibular complex in double-jaw surgery is a well-accepted technique in orthognathic surgery, while counterclockwise rotation has not been supported as an acceptable treatment modality. But recently, Wolford et al. Reported the stability of occlusal plane after double-jaw surgery in patient who had an increase or decrease in occlusal plane angulation. And, he concluded that counterclockwise rotation of the maxillomandibular complex is a stable and predictable procedure. The object of this study is to retrospectively evaluate the stability of occlusal plane after Le Fort I maxillary osteotomy using miniplate fixation in patients with skeletal class Ⅲ malocclusion. In this study, eight patients were evalated with preoperative, immediate postoperative, and long-term postoperative lateral cephalometric radiographs. These serial cephalometric radiographs of patients with skeletal class Ⅲmalocclusion, who was selected among the patients performed double-jaw surgery, had superimposed with cephalometric error of SN plane within 1mm. In conclusion, average long-term follow-up changes of occlusal plane angle were -0.9°(1.3° with FH plane and 0.0°(1.2° with SN plane. These results demonstrated that occlusal plane after Le Fort I maxillary osteotomy in patients with skeletal class Ⅲ malocclusion was stable.

교근 비대증은 교근의 크기 증대와 함께 하악골 우각부의 골성 팽창으로 인해 안모의 비대칭 혹은 사각형의 안모를 야기시키는 비교적 드문 양성 병변으로서 편측성 또는 양측성으로 발생할 수 있다. 교근 비대증의 가장 주된 증상은 수개월 혹은 수년간에 걸쳐 하악골 우각부에 서서히 커지는 무통성의 종창으로 환자는 주로 심미적인 문제의 해결에 주된 관심을 가지게 되고 따라서 이에 대한수술의 목적은 심미적인 면이 대부분을 차지한다고 볼 수 있다. 교근 비대증의 원인은 아직까지 확실하지 않으나 여러 학자들에 의해 다양한 가설들이 제기되었으며, 그 가운데 부정교합, 꽉 다물기, 야간 이갈이, 불량한 저작습관 등으로 인한 과도한 하악운동으로 발생하게 되는 생리적 운동성 비대증이 가장 널리 받아들여지고 있다. 교근 비대증은 특히 편측성인 경우 임파종, 혈관종등의 하악골 양성 및 악성종양, 그리고 이하선 종양등과의 감별진단이 중요하나 임상적, 방사선학적 검사에 의해 비교적 쉽게 진단될 수 있으며, 방사선검사는 주로 파노라마 및 정모 두부계측 방사선사진, 초음파 방사선사진, 전산화단층 방사선사진, 그리고 자기공명 방사선사진이 사용될 수 있다. 교근 비대증의 치료는 주로 외과적인 수술로 이루어 지는데 심미적인 면을 고려하여 구내 접근법에 의한 교근과 하악골 우각부 절제가 수술방법이다. 교근 비대증으로 진단된 7명의 환자를 구내 접근법에 의한 하악골 우각부 절제술과 함께 교근 절제술을 시행하는 하악 우각부 미용 성형술을 통해 심미적으로 만족할 만한 결과를 얻었기에 교근 비대중의 원인, 외과적 수술기법 및 절제된 조직편의 조직학적 소견등을 문헌고찰과 함께 보고하는 바이다. 7 patients of masseter muscle hypertrophy were operated on for aesthetic contouring of the prominent mandibular angle and/or resection of hypertrophic masseter muscle because of a cosmetic reason. The age of patients ranged from 19 to 30 years involving 4 females and 3 males and a follow-up period from 2.5 to 1.2 years. Masseter muscle hypertrophy is the physiologic condition which increases the size of the masseter muscle with bony enlargement of the mandibular angle. The most frequent complaint is asymptomatic swelling that has slowly enlarged over several years, especially a cosmetic problem. Clinical examination usually suggests palpable painless swelling in the mandibular angle. Radiographic examination, such as panoramic and cephalometric radiographs, ultrasonography, and Ctor MRI shows a hypertrophic masseter muscle and prominent mandibular angle. The cause of masseter muscle hypertrophy is not clear, although several theories have been advanced. Masseter muscle hypertrophy is mainly is mainly treated surgically for the purpose of aesthetic oontouring. In this article, a surgical mathod via an intraoral approach in facial bone contouring through the curved osteotomy of the prominent mandibular angle for correcting the prominent mandibular angle that is caused by a posterior projection and lateral flaring of the gonial angle.

안면골 골절 환자에 대한 Halothane 마취 후 발생한 Halothane Hepatitis

이재휘(Lee Jae Hwy),이영현(Lee Young Hyun) 대한구강악안면외과학회 1991 대한구강악안면외과학회지 Vol.17 No.3

General anesthesia is necessary to operation in dept. of oral and maxillofacial surgery. Halothane is one of the most commonly used anesthetic agent for general anesthesia. Halothane is a nonexplosive fluorinated hydrocarbon anesthetic agent and structurally similar to chloroform. Halothane has been reported to result in severe hepatic necrosis in a small number of individuals. A genetic predisposition leading to an idiosyncratic metabolic reactivity has been postulated. We experienced and reported 3 cases of halothane hepatitis that occured following halothane anesthesia for facial bone fracture with the review of the relevant literatures.

하악골 좌우측 우각부 골절후 좌측 우각부에서 발생한 골수염의 치험례

이재휘(Lee Jae Hwy) 대한구강악안면외과학회 1992 대한구강악안면외과학회지 Vol.18 No.2

In a strict sense, any inflammatory lesion that involves the marrow can be referred to as osteomyelitis. Osteomyelitis can occur at any age and is most common in males. Although in infancy the maxilla is usually involved, during childhood and later life the mandible is the preferred site. Aute axacerbation of periapical lesions and fractures are the precipating factors. Staphylococci and streptococci are the usual causative organisms, but osteomyelitis may be caused by other organisms such as Actinomyces israelii and tubercle bacillus. The treatment of teeth in the teeth-bearing mandibular fracture is controversial. The teeth in the mandibular fracture line can be preserved with the proper antibiotic therapy, but in the case of complication, especially impacted third molar, the teeth in the mandibular fracture line must be extracted for preventing osteomyelitis. The following report concerns rarely patient who suffered pus-producing osteomyelitis only in the left mandibular angle following both mandibular angle fractures with full impacted third molar.
