We have reviewed 73 patients who experienced hemoptysis with pulmonary tuberculosis to analyze the factors contributing hemoptysis and its management The result are; 1. The age group between 30 * 50 years old was major prevalent group [59%]. 2. Sexual ratio was 3.9 to 1, as 58 men and 15 women. 3. In 58 patients [79.5 %], the number of hemoptysis in frequency was less than 5 times. 4. The quantity of hemoptysis was ranged from less than 50 ml to more than 600 ml and 20 patients [27.4%] experienced bleeding more than 600 ml at once. 5. There was no seasonal difference in hemoptysis. 6. The common prodromal symptoms of hemoptysis were coughing, fatigability, hot foreign sensation of throat in order of frequency. 7. In chest roentgenographic finding, the cavitary lesion was the most common finding, 67% [51 cases], and the multiple cavity was 19.2%[14 cases]. 8. 23 patients [31.37%] were operated for control of hemoptysis and pulmonary tuberculosis itself, 7[30.43 %] of them suffered from complication of empyema, respiratory failure, empyema with bronchopulmonary fistula. 9.

Takayasu`s arteritis is an arteritis of unknown etiology involving larger elastic arteries such as aorta and its branches, pulmonary arteries, and rarely coronary arteries. The late pathologic feature is vascular obstructive change and the resulting clinical manifestations are local ischemic symptoms such as syncope, visual disturbance, claudication of extremities, hypertension, and angina. the disease occurs predominantly in females, with the age of onset between 10 and 30 years. Recently we have experienced one case of Takayasu`s arteritis involving aortic arch and all its major branches. The patient was 36 year-old female and she was admitted because of headache, blurred vision, and easy fatigability and motor weakness of upper extremities. Aortogram revealed total obstruction of both carotid arteries at the site of its origin and partial irregular obstructive change in the innominate artery and both subclavian arteries. Bypass graft surgery using Gore-Tex grafts was performed with successful result.

Myasthenia gravis is usually defined as a state of abnormal fatigability. The cause of myasthenia gravis is not known. Several disorders tend to occur more frequently in patients with myasthenia gravis, such as hyperthyroidism or other thyroidal disorder. Anesthetic experience with thymectomies for two patients with myasthenia gravis has been reported. Both of them tolerated the surgical procedures under endoteracheal Nitrous oxide-Oxygen-Halothane anesthesia well. Diagnosis and clinical features including choice of preanesthetic medication, anesthetic agents, techniques and of neuromuscular blocking agents for myasthenic patients have been discussed. Paramount importance of rigid attention to ventilation, the maintenance of a patent airway and the removal of secretions whenever necessary for the patient safety throughout operative and postoperative period has been stressed.

Objectives : The surgical results of 80 patients with growth hormone(GH)-producing pituitary adenoma were analyzed retrospectively to evaluate the clinical manifestations and to determine which preoperative factors significantly influenced the surgical outcome. Patients and Methods : The patients consisted of 39 men and 41 women and the age of patients at the time of initial operation ranged from 17 to 67 years(mean age, 40.5 years) Between January 1990 and June 1996, 77 patients underwent transsphenoidal surgery and 3 patients underwent craniotomy for GH-producing pituitary adenoma at our institution. Preoperative administration of octreotide was performed in 18 patients. Surgical control was defined as a postoperative serum basal level of GH less than 5ng/ml. A logistic regression model was used for univariate and multivariate analysis. Probability value of less than 0.05 was considered as statistically significant. Results : The most common presenting symptom was acromegaly, followed by headache, visual disturbance, and fatigability. Visual symptoms were present in 39% of the patients. Diabetes mellitus was associated in 24 patients and hypertension in 12. Preoperative mean basal level of GH was 93.2ng/ml(range 72-500ng/ml) which was closely related with tumor size(p<0.05). Grade II by Hardy's classification was the most common radiological type. Preoperative octreotide treatment significantly reduced the level of GH(p<0.05), but not enough to induce endocrinological remission. One patient died of cerebral infarction after craniotomy. The most common surgical complication was transient diabetes insipidus. The symptom of the earliest improvement after surgery was paresthesia and tightness of the hand and foot, followed by headache and easy fatigability. The preoperative visual symptom was improved in all patients. The patients who had hypertension or DM experienced alleviated symptoms in 67% and 92%, respectively. The overall rate of endocrinological remission was 44%. By multivariate logistic regression analysis, the size of tumor, extrasellar extension, and extent of removal were significant prognostic factors for endocrinologial remission. Conclusion : Early detection of a small tumor without extrasellar extension followed by a complete resection is highly recommended in order to achieve endocrinological cure of GH-producing pituitary adenomas.

The paper will present chip formation mechanism and surface integrity generation mechanism based on the systematical experimental tests. Some basic factors such as the end milling cutter tooth number, cutting forces, cutting temperature, cutting vibration the chip status, the surface roughness, the hardness distribution and the metallographic texture of the machined surface layer are involved. The chip formation mechanism is typical thermal plastic shear localization at high cutting speed with less number of shear ribbons and bigger shear angle than that at low speed, which means lack of chip deformation. The high cutting speed with much more cutting teeth will be beneficial to the reduction of cutting forces, enlarge machining stability mot depression of temperature increment anti-fatigability as well as surface roughness. The burrs always exist both at low cutting speed and at high cutting speed. So the deburring process should be arranged for milling titanium alloy in my case.

The purpose of this study was to elucidate the general characteristics, antheropometric values and health-related characteristics of the rural elderly population according to their Sasang constitutions. The participants in this study were 31 in Taeeumin group, 29 in Soyangin group, and 15 in Soeumin group. The present study was performed using self-administration questionnaires, antheropometric and biochemical analysis. There were no significant differences in height, weight, BMI, diastolic blood pressure and alcohol habits between the Sasang constitutions. In the analysis of physical activity, Soyangin had a higher value than the other groups. Compared with the other groups, Soeumin also had considerable resistance to stress($101.1{\pm}26.2$ point). Furthermore, in the analysis of fatigability caused by stress, Soeumin was mostly shown to feel less fatigue than the other groups. On the other hand, Taeeumin appeared to feel more fatigue. In the biochemical analysis of blood, there was no significant difference between Sasang constitutions.
