양동환(Dong-Hwan Yang),최성희(Sung-Hee Choi),현숙경(Sook Kyung Hyun) 한국차학회 2021 한국차학회지 Vol.27 No.4
국산 차류의 기호성, 기능성 강화를 위한 기초연구로 레몬, 제주도산 영귤 및 감귤 등의 과피류를 녹차 혹은 홍차에 2:8 (w/w)비율로 첨가하여 제조한 블렌딩 차류를 제조하였다. 블렌딩 차류의 기호도에 관련된 휘발성향기 성분을 Likens and Nickerson형 동시증류추출(SDE)장치를 사용하여 추출하고 GC-MS (Gas ChromatographMass Spectrometer)를 이용하여 분석 및 동정하였다. 감귤류 과피-차류 블렌딩에서는 구수한 향이 감소하지만 달콤한 향은 증가하는 경향이 보이고 홍차 블렌딩보다 녹차 블렌딩에서의 증가폭이 더 컸다. 따라서 대작 녹차에서 감귤류 과피를 첨가함으로써 달콤한 향을 보완해 주었다. 감귤류 과피-녹차 블렌딩의 공통적인 향기 특징으로 박하향과 꽃향이 증가하였고 특히 시트러스향이 크게 증가하였다. 시트러스향을 띄는 limonene은 감귤류의주된 정유성분이며 γ-terpinene은 limonene의 이성화로 생성되는 물질로 감귤류 특유의 향긋한 향을 낸다. Myrcene은 β-pinene의 열분해로 얻어지는 감귤류 과피에 많은 성분으로 sweet balsamic 향기특성을 나타내며, α-pinene과 β-pinene은 소나무향을 내는 향기물질이다. The flavor compounds in green teas blended with citrus peels (lemon, sudachi, and mandarin) were extracted by the simultaneous distillations and extraction method. The concentrated flavor extracts were analyzed and identified by gas chromatography-mass spectrometry. The sweet flavor tended to increase in the citrus peel blended tea, and the increase was larger in the blended green tea than in the blended black tea. Therefore, the sweet flavor was supplemented by adding citrus peels to green tea. Mint and flower aroma were increased as common aroma characteristics of the citrus fruit peel-green tea blending, and especially, the citrus flavor was greatly increased. Limonene, which has a citrus flavor, is citrus fruits main essential oil component. γ-Terpinene is a substance produced by the isomerization of limonene, which gives off a unique fragrance of citrus fruits. Myrcene is a component of many citrus peels obtained by thermal decomposition of β-pinene and exhibits sweet balsamic aroma properties. In addition, α-pinene and β-pinene are fragrance substances that give off the note of pine.

Necrotizing fasciitis is rare acute infection showing rapidly necrosis involve the subcutaneous tissue and fascia. If treatment is delayed, infection can spread to involve the subcutaneous tissue, skin, deep fascia, and even muscle in rapid sequence, resulting in widespread necrosis and moderate to severe systemic toxicity. Most commonly this disease presents in the extremities, trunk, and perineum; it is relatively rare in the head and neck regions. If not diagnosed and treated in its early stages, necrotizing fasciitis can be potentially fatal, with a motality rate approaching 40%. Historically, the clinical entity now referred to as necrotizing fasciitis was described in the literature under various name. : hospital gangrene, necrotizing erysipelas, streptococcal gangrene, suppurative fasciitis. Necrotizing fasciitis was first described by Wilson in 1952. We experienced 3 cases of necrotizing fasciitis and will report review of literature with diagnosis, treatment, complication and consideration.

악관절에 발생한 활액성 연골종증(Synovial Chondromatosis) ; 증례보고
김일규(Il Kyu Kim),최진호(Jin ho Choi),오성섭(Seong Sub Oh),오남식(Nam Sik Oh),김형돈(Hyung Don Kim),이성호(Seong Ho Lee),양동환(Dong Hwan Yang) 대한구강악안면외과학회 2000 대한구강악안면외과학회지 Vol.26 No.1
Synovial chondromatosis is an uncommon disease of cartilage transformation of synovial membrane with formation of loose bodies within the joint space. The knee and elbow are the most commonly involved sites and involvement of temporomandibular joint is very rare. Symtoms include swelling, pain, stiffness of the jaw, and inability to close the jaw. A case involving the temporomandibular joint(TMJ) is presented. A 28-year-old women had experienced pain of the left TMJ area and limitation of mouth opening. Radiographs of the left TMJ revealed calcified mass surrounding over the mandibular condyle and under the glenoid fossa. Treatment consisted of removal of calcified mass, reshaping of affected condyle and reconstruction with a auricular cartilage. After surgery, the patient’s range of motion improved although deviation to the affected side. Until present after surgery there have been no recurrence of symtoms. We think that findings of this patitent agree with those of synovial synchondrmatosis in many aspects.

This study is comprised of data obtained from the files of 346 patients with temporomandibular disorders. All patients were diagnosed, treated and followed in the Department of Dentistry at the Inha university hospital, Incheon, Korea. The patients had treated with medications, physical therapy, occlusal splint and arthrocentesis. The study data were obtained from the medical records and telephone interviews that were conducted by research assistants. The results were as follows 1. The patient’s main complaint was pain(77%), and mouth opening limitation was 17%. 2. An analysis of the medical records of the 346 patients disclosed that 82% were improved and 17% had no improvement when they were dismissed. 1% of the patients had become worse during therapy. 3. A success rate of 82% was achieved when medication assisted physical therapy was included. In the current status at the telephone interview, 270 patients(89%) reported that they were doing well with 56% describing themselves as asymtomatic and 32% experiencing only minor residual or recurrent symptoms. 11% regarded themselves as unimproved and worse. 4. In the current status of the unsuccessfully treated patients by medications and physical therapy, 64% of patients were doing well(3% as asymptomatic and 56% as only minor residual or recurrent symptom). But 36% of patients was reported as unimproved and worse. 5. TMJ has a remarkable adaptive potential and TMJ disorder has a natural history of spontaneous fluctuations and favorable prognosis during the subsequent natural course. 6. In the treatment of the temporomandibular disorders, there is a treatment ladder, starting with the simplest and least expensive treatment, that is ascended until resolution of the patient’s symptoms occur. These findings suggest that conservative reversible therapies are both sufficient and appropriate for management of temporomandibular disorder in most patients. Major alterations of mandibular position or dentoalveolar relationships do not appear to be necessary for obtaining either short term or long term success and therefore they can be generally regards as inappropriate treatment for this disorder. The fact that physical therapy is non-invasive and does not appear to be fraught with irreversible changes, makes it a very applicable vehicle in the area of clinical TMJ disorder management.

4세 유아에 발생한 몰입성 하마종(plunging ranula); 증례보고
최진호,양동환,김일규,오남식 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.4
Whereas oral ranula is relatively common and presents as a cyst in the mouth, the plunging ranula is rare and manifests itself as a mass in the neck with or without an associated oral lesion. When there is a soft anterior neck swelling without oral swelling, diagnosis is still difficult. In such a case, clinical suspicion may be low and the pathologist may be misled by the histologic appearance. Recognition of the diagnosis of plunging ranula is essential for the correct treatment of these lesions We report a case of a 4-year-old girl and review the literatures to discuss the differential diagnosis and treatment modalities.
