The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

윤중호,김기정,정상훈,박광호,박정현,김형곤 大韓顎顔面成形再建外科學會 1994 Maxillofacial Plastic Reconstructive Surgery Vol.16 No.4

A thirty two year-old male was referred with a chief complaint of mouth opening limitation, and maxillofacial pain including left TMJ area. The patient had been treated in a private clinic with medications and conservative treatments, without any improvements in symptoms. MRI findings showed a limitations in condylar head movements, and signs of disc adhesion without the Positional change. Panoramic views showed elongation of stylohyoid process. Brain C-T was taken due to the patient's complaint of headache, facial pain, and paresthesia of tongue, and the result showed no abnormalities. The first surgery included meniscoplasty and the removal of disc adhesion of left TMJ under the preliminary diagnosis of internal derangement with adhesion, and the patient displayed marked improvements in opening movements despite of persistent hemiparesthesia of left facial areas and tongue, and mild dysphasia. Therefore, the second surgery was carried out with the preliminary diagnosis of Eagle's Syndrome, and a resolution of neurologic symptoms was obtained. The final diagnosis of this case was Eagle's Syndrome with internal derangement, and the difficulties in diagnosis and treatment might be due to the existence of two separate diseases with similar symptoms.

윤현주,이제호,윤정훈,이종갑 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.1

Langerhans Cell Histiocytosis는 Langerhans Cell 의 비정상적인 증식을 특징으로 하는 질환이다. 임상적 양상은 단독 골병소에서부터 여러 장기를 침범하여 치명적인 경우까지 매우 다양하게 나타나며, 나이가 어릴수록, 침범된 장기의 수가 많을수록 예후는 좋지 않다. 악골의 경우는 전체 Langerhans Cell Histiocytosis 환자의 10~20%에서 나타나며, 주로 초기에 이환된다. 본 환아는 만 3세 때 하악골 전반에 걸친 동통으로 본 치과병원에 내원하여 조직학적 검사를 통해 Langerhans Cell Histiocytosis임을 확진 받은후 소아과에 의뢰되어 화학요법에 의해 치료되었다. 재발의 가증성이 있어 현재 주기적 검사중이며, 하악 좌측 제2소구치배의 상실로 인해 향후 교정치료 및 보철치료가 필요하리라 사료된다. 본 증례는 치과병원에서 Langerhans Cell Histiocytosis임을 확진한 후 조기치료를 시행해 주어 양호한 결과를 얻었기에 보고하는 바이다. Langerhans Cell Histiocytosis(LCH) is characterized by proliferation of Langerhans cells. The clinical manifestation varies from solitary bone lesion to multi-system, life threatening disorder. The younger the patient is and the more system is involved, the worse the prognosis is. The jaw is involved 10~20 percent of all LCH and it is involved usually in early stage of LCH. In this case the patient is three years old girl who suffered from pain of whole mandibular body and histological examination confirmed the dignosis LCH. She is referred to pediatrics and managed with combined chemotherapy. Due to the possibility of recurrence, we follow up the girl and she need orthodontic and prosthodontic treatment in the future because of the loss of lower left 2nd premolar. We report this case because early recognized LCH in dental hospital result in good prognosis.

후천성 림프관종과 동반한 소타액선의 선종양 증식

윤정훈,조세인,김수관 大韓顎顔面成形再建外科學會 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.6

A 24-year-old male presented clinically as an asymptomatic tumor-like nodule associated with superficial multiple hemorrhagic papules on the right retromolar area. A histological examination revealed acanthotic epithelium and dilated lymphatic vessels in the submucosa together with a proliferation of mucous salivary gland tissue. The clinical and histological features were compatible with those of lymphangiectasis or acquired lymphangioma and adenomatoid hyperplasia of the minor salivary glands. This patiend had past history of third molar extraction 2 years ago. The exact nature of this lesion is not known, but obstruction of the lymph vessels due to a pervious tooth extraction has been suggested as a possible cause. In addition, local trauma may play a role of the pathogenesis of adenomatoid hyperplasia of the minor salivary glands.

어린이의 하악골에 발생한 결합조직형성 섬유종(Desmoplastic fibroma) 1예

윤정훈,이제호 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.1

결합조직형성 섬유종(desmoplastic fibroma)은 국소적으로 공격성을 보이는 골내 양성종양으로, 연조직에 발생하는 섬유종증(fibromatosis)이나 유건종(desmoid tumor)의 골내 대조병변이다. 이 종양은 대개 30세 이하의 비교적 어린 나이에 발생하며, 가장 흔한 주소와 증상은 구강 내와 구강 외의 무통성 종창으로 안모변형을 일으킨다. 환아는 약 한달 전부터 시작된 좌측 안면부 종창을 주소로 본원에 내원한 9세 남아로 종창부위를 만져보면 통증은 있지만, 악하 림프절 증대는 없었다. 파노라마 사진에서 #33과 #34 치아 사이에 비교적 경계가 분명한 방사선 투과상 병소가 관찰되었다. 임상적으로 좌측 하악체 부위에는 양성 치성종양이 , #46 치관 부위는 함치성 낭이 있는 것으로 추정하고 구강악안면외과에 의뢰하여 종양 및 낭 제거술을 시행하였다. 병리조직학적으로, 종양은 방추형의 섬유모세포의 증식과 교원섬유의 침착이 특징이었다. 이 증례에서 치아 및 악골이 발육중인 어린이의 경우 안모 손상을 초래할 수 있어 광범위한 외과 술식은 피하였다. 그러나 이 종양의 재발율이 높은 점을 고려하여 세심하고도 철저한 추적관찰이 필요하며, 추후 재발 시에는 악골 절제도 고려해야 할 것으로 생각한다. This case describes a case of desmoplastic fibroma of the mandible. A 9-year-old boy was seen with a history of progressive swelling and expansion of the left mandible for one month period. Desmoplastic fibroma was diagnosed on histopathologic examination. This report reviews the diagnostic criteria, differential diagnosis and surgical treatment of choice in brief of this uncommon primary bone tumor of the oral and maxillofacial region

윤양진,정미라,이훈식,서국웅,박승범 釜山大學校 附設 體育科學硏究所 1998 體育科學硏究所 論文集 Vol.14 No.-

Sports technology encompasses a wide range of disciplines from biomechanics to engineering. As a consequence, researchers working in sports technology find that their work falls neither in the field of traditional sports nor in mainstram engineering. Also Sports Engineering is an international journal publishing original papers on the application of engineering and science to sport. The journal intends to fill the niche area which lies between classical engineering and sports science and aims to bride the gap between the analysis of the equipment and of the athlete. Area of interest include the mechanics and dynamics of sport, the analysis of movement, instrument equipment design, surface interaction, materials and modeling. These topics may be applied to technology in almost any sports. The Sports Engineering will be of particular interest to Engineering, Physics, Mathematics and Sports Science Departments and The International Sport Engineering Association(ISEA) will act forum where research, industry and the sports sector can exchange knowledge and innovative ideas.

변연성 발육성 치아종 : A Case of Peripheral Developing Odontoma

윤정훈,임경수,손홍범 조선대학교 구강생물학연구소 2003 Oral Biology Research (Oral Biol Res) Vol.27 No.1

A peripheral odontoma is a relatively rare lesion and is thought to represent the soft tissue counterpart of the central or intraosseous odontoma. Although several odontogenic tumors can occur peripherally, only a few cases of peripheral odontomas involving the gingival tissues have been reported. No earlier stage of peripheral odontoma or peripheral developing odontoma has been described. Here, we report a case of a peripheral developing odontoma occurring in the gingiva of a 4-rear-old Korean boy. Microscopic sections showed several nodules of developing rudimentary tooth germ-like structures in the gingival tissue. It seems likely that this case arise from remnants of the dental lamina located in the gingiva, since the clinical and histologic presentation lends support to the peripheral origin of this tumor.
