Between 1979 and 1991 thymectomy was performed on 31 patients with myasthenia gravis at the department of thoracic and cardiovascular surgery, Keimyung University medical school. All patients were treated by transsternal thymectomy. During follow-up period that ranged from a month to 10.7 years[mean 2 years], the remission rate for the entire group was 16.1 percent and an additional 71.0 percent had improvement [87.1 percent benefited]. In those 8 patients with thymoma, the remission rate was 12.5 percent with 75.0 percent of the patients benefiting from operations The remainimg 23 patients fared better the operations: 17.4 percent had remission and a total of 91.4 percent benefited. There was no mortality, I concluded that most patients with myasthenia gravis will benefit from thymectomy, and that the improvement persists over an extended period of time in a high percentage of patients.

Thymus gland is a kind of endocrine organ which secretes thymosin and thymoprotein. There can be developed variable lesions like thymoma, thymic hyperplasia, thymic cyst, thymolipoma, and carcinoid tumor of the thymus gland. We have experienced 25 patients of thymic disease: thymoma 12, thymic hyperplasia 11, thymic cyst 1, carcinoid tumor 1. The age distribution were ranged from 3 to 66 years and the sex ratio was 1:1.8 [male to female]. Thymectomy was performed in all cases, but 3 cases with deep infiltration to the adjacent structures were not resectable completely. Malignancy [all thymoma] were 5 and the rest were benign. Two cases were died of recurrence after tumor resection. Myasthenia gravis occurred in 10 cases. Among them, 2 were thymoma and 8 were thymic hyperplasia. We could obtained the result that thymectomized cases reached 2 remission and 5 improvement. Myasthenia gravis treated medically [18 cases] had no remission and only 2 clinical improvement. In the light of these results, early radical thymectomy would be most favorable treatment in not only thymic tumor, but generalized myasthenia gravis.

A 15 year-old boy was referred to us because of mild dyspnea on exertion and incidentally found heart murmur. On echocardiography, a mass involving mainly interventricular septum and causing left ventricular outflow tract obstruction was detected. Cardiac catheterization demonstrated a transaortic pressure gradient of 20 mmHg. Partial excision of the septal mass was performed via aortotomy under cardiopulmonary bypass. The pathologic diagnosis revealed myocardial hamartoma. The lesion was mainly composed of mature, severely hypertrophic myocytes and intervening fibrosis. During the 5 year of follow-up after the surgery, no evidence of arrhythmia or tumor recurrence was documented.

본 연구목적은 한국어판 실어증감별진단검사를 이용하여 2회 이상 경과를 검토할 수 있었던 Broca실어의 3증례에 있어서의 개선경과를 초회평가시의 실어증 중등도가 거의 같은 일본의 장기 관찰예와 비교하여 장애 pattern의 검출 및 개선경과의 추적에 있어서의 한국판 실어증 감별진단검사의 유효성을 검토하였다. 그 결과, 신경학적으로 안정되어있는 실어증환자의 경우 중증도별로 보면, 언어과정 전반의 득점 profile은 유사성이 높았으며, 치료경과에 양국어의 일반성과 특수성이라고 하는 면에서는 금후 한층 더 상세한 토의가 요구되었다.

Over a 3 year period, 10 premature infants with less than 37 weeks of gestational age underwent ductal ligation for patent ductus arteriosus. No patient died during operations which were done at a mean age of 30 days. One late death at 2 months after operation was not directly attributed to operative procedure. Follow-ups were done in 9 survived patients from 2 to 26 months. Results suggest that surgical ligation is a feasible and effective method for treating symptomatic premature infants with patent ductus arteriosus.

Repetitive nerve stimulation is a simple and widely used technique to demonstrate neuromuscular transmission defect. A significant decremental response for repetitive hypoglossal nerve stimulation was obtained from the surface recordings in the tongue of a patient with dysarthria and dysphagia. Repetitive hypoglossal nerve stimulation test may be useful in diagnosis of myasthenia gravis with bulbar symptoms only. We utilized repetitive hypoglossal nerve stimulation with tongue recordings and diagnosed a case of myasthenia gravis.

B-모드 초음파를 이용한 경동맥 내중막 두께(IMT intima-media thickness) 측정은 관상동맥 질환이나 허혈성 뇌질환 위험도의 독립적인 인자로 매우 중요하다. 본 연구에서는 NTSC(national television system committee) 방식으로 경동씩 초음파 동영상신호를 획득하여 프레임으로 나누어 각각의 IMT를 측정하였다. 각각의 측정값을 시간축으로 재구성하여 시간도메인에서 IMT 의 시변동성을 분석하였다. IMT 시변동성 분석을 통하여 상대적으로 부정맥피험자가 정상피험자에 비해 IMT 평균값이 작아 위험도가 낮다고 평가 될 수 있지만 시변동성 분석으로 IMT 평균값이 작아도 혈관의 기능적 특징이 부족하여 위험도가 높다는 것을 알 수 있었다. 경동맥의 형태적 특징과 기능적 특징을 반영하는 이 분석방법은 경동맥 내중막 두께측정의 신뢰성을 향상시키며 관련질환의 위험도와 중증도를 세분화 할 수 있는 새로운 방법이 될 수 있을 것이다.

Objectives : The purpose of this study is to report the effectiveness of Gagamhwajung-hwan in five severe alopecia areata patients. Methods : This case study was conducted for five severe alopecia areata patients who visited Korean Medicine Clinic. Herbal medicine(Gagamhwajung-hwan) was prescribed to all five patients. Improvements of patients were evaluated by photographs and SALT(Severity of alopecia tool) scale. Results : According to photographs, hair loss of each patient was completely improved. SALT scale was also decreased in all five patients. Conclusions : This study shows the possibility of using Gagamhwajung-hwan to treat severe alopecia areata.

Frequently, we have been noted foreign bodies in air way, which can produce different signs and symptoms needed for differential diagnosis with other diseases. Occasionally, it can be followed by some pulmonary complications and removal difficulty. Therefore it can be serious and fatal in few cases, especially in children. Three cases were evaluated with clinical and roentgenographic features of air way obstruction due to foreign bodies and discussed with previous many literatures.

Background: Atopic dermatitis is chronic exzemaous dermatosis characterized by severe itching, licalized eruption and chronic relapsing progress and has familu history of atopic diseases and hereditary disposition. This Study is attempted in order to estimate of possibility of oriental treatment on atopic dermatitis. Objective: We studied 24 years old women with atopic dermatitis from June 2004 to July 2004 Method: We treated her with herb medication and used three index to assess the severity of atopic dermatitis. Results: Each index show us about 50-60$\%$ of improvement Conclusion: On the basis of this study, It should be considered that treatment of atopic dermatitis should be focused on fever of yang-ming.
