Leiomyoma is one of the rarest solid tumor of the ovary. Approximately 50 cases have been published to date. However, most reported leiomyoma of the ovaries were small and rarely induced serious symptoms. We report a case of ovarian leiomyoma in 57-year-old woman which has been experienced in our haspital with brief review of literature.

BACKGROUND: To collect the data related to the prevention of death in pediatric patients in the emergency center, the authors made a clinical analysis of pediatric death patients who visited the emergency center of Wonkwang University Hospital. METHODS: The authors performed a retrospective analysis of 49 pediatric deaths under the age of 16 years, observed in the Wonkwang University Hospital emergency center from January 1st, 1995 to December 31th, 1996. RESULTS: 1) Among a total of 49 pediatric patients who died (24 patients in 1995 and 25 patients in 1996), 19 patients were dead on arrival and 30 were died after arrival. 2) The cause of death of all the patients of 1 to 5 years old was the accident, and that of the majority patients of less than 1 year was disease. 3) We observed the diurnal variation in pediatric death and the rate was higher between 12:00 to 6:00. P.M. 4) Iksan city was the most common place of residency of the patients(71.4%) 5) 36 patients (73.5%) died from traffic accidents and 29 of them were victims of pedestrian traffic accidents. 6) The most common cause of death in accidents was head injury(54%). CONCLUSION: The majority of the pediatric death patients observed in our emergency center was involved in pedestrian traffic accident, head injury, so we conclude that team approach with pediatric trauma specialist could decreased unwanted pediatric deaths.

BACKGROUND: To collect the data related to the clinical analysis of suicidal attempters who visited the emergency center of WonKwang University Hospital. METHODS: The authors performed a retrospective analysis of 306 suicide attempters, observed in the WonKwang University Hospital Emergency Center from January 1st, 1998 to December 31th, 1998. RESULTS: 1) Factors related to increased occurrence were male(1.1:1), age of 2nd, 3rd & above 6th decade. 2) Poisoning was the most common method of suicidal attempt(90.8%). 3) The average observation time was 18.76+/-23.3 hour and average staying time in admitted patients were 40.4+/-32.3 hour. 4) Mortality rate was in male 23.1%(37/160) and in female 10.0%(15/146). 5) Among the suicidal attempters who admitted, 56 patients were admission(11.8%). 6) Consultant of neuropsychiatric department was only 10.5%(18/172), and most common underlying psychiatric disorder was depression(10/18). CONCLUSION: 1) To develope observation room decrease staying time in suicidal attempters. 2) All suicidal attempters were necessarily neuropsychiatric consultant and continuously follow-up.

BACKGROUND: It has been well known that cFos protein, one of the immediate-early gene proteins, was a cellular marker to characterize physiological or anatomical property of neural networks in mammalian brain. The purpose of this study was to evaluate quantitative change of cFos protein expression in rat brain nuclei concerned with regulation of blood pressure according to severity of hypotension and compare the spatial pattern of cFos between hemorrhagic hypotension and non-hemorrhagic hypotension elicited by vasodilatation. METHODS: The mean blood pressure (MBP) in the femoral artery was recorded by using pressure transducer and polygraph. Nitroprusside was injected into the femoral vein with constant flow rate by means of osmotic pump in which the dosage was 5microgram Per kg a minute. Immunohistochemical staining was Performed by using conventional ABC method to visualize cFos-like immunoreactive (cFLI) neurons in many brain nuclei and FLI cells were counted by image analyser. RESULTS: Mild hemorrhage group with MBP of 70-80 mmHg showed significant increase of cFLI expression in the paraventricular nuclei and supraoptic nuclei. In contrast, severe hemorrhage group with MBP of 50 mmHg increased significantly cFLI expression in the rostral ventrolateral medulla, periventricular thalamic nucleus, central gray matter, medial vestibular nuclei as well as the nuclei seen in mild hemorrhage group. Nitroprusside induced hypotension exhibited a similar spatial pattern of ctrl expression to severe hemorrhage group. CONCLUSION: These results suggest that severe reduction of blood pressure induces expression of cFLI neurons in the neural network systems that control vital organs.

To evaluate the influence of tourniquet ischemia and hyperthermia on the radiation effect of skin, theexperimental study was undertaken using a total of 344 mice. A single dose of irradiation from 2000 rads to 8000rads was delivered on skin of mouse tail after hyperthermia of 40degrees(C) to 42degrees(C) with or withouttourniquet application in various subgroups. The resuls are summarized as follows; 1. Tourniquet ischemia duringirradiation caused radioprotective effect. 2. Hyperthermia before irradiation induced radiosensitizing effect,which was increased with temperature elevation of hyperthermia. 3. In combination of tourniquet ischemia andhyperthermia, evident radiosensitizing effect waas noticed. This enhancing effect on irradiation was greater thanthe effect i hyperthermia only. It could be suggested that the combination of tourniquet application andhyperthermia might be intorduced in clinical radiotherapy after trail of clinical experiments on applicable typeand sutiable location of tumors.

Takayasu's arteritis is an arteritis of undetermined etiology, which affects the aorta, the proximal portions of its major branches, and the pulmonary arteries, and causes coarctation, occlusion, or aneurysmal dilatation of the affected vessels. Authors has reported 9 cases in 1973, and another 24 cases in 1977. Thereafter, during next 4 years, authors experienced another 42 cases and obtained some additional results. The results are as follows: 1. Among 75 cases, 10 are male and 65 female patients with sex ratio of 1:6.5, and about 2/3 of total patients are under 30 years of age. 2. Headache, dizziness, absent or weak radial pulse and hypertension are the most common symptoms and signs. 3. Conventional chest roentgenography may be helpful but not specific in diagnosis of Takayasu's arteritis. 4. The aortographic findings are characteristic and pathognomonic in diagnosis of Takayasu's arteritis. In our series, the most common findings are stenosis or occlusion of subclavian artery, diffuse narrowing and aneurysmal dilatation of abdominal aorta and its branches, narrowing with irregular contour of descending thoracic aorta, and renal artery involvement. 5. Involvement of the aorta was classified as extensive type in 38 cases, descending thoracic and abdominal type in 22 cases and arch type in 15 cases. 6. As total aortography in cluding abdominal aorta uncovers evidence of unsuspected involvement of aorta and its branches, it is of paramount importance in the diagnosis of Takayasu's arteritis.

In order to evaluate the ability of spin-echo MR imaging to differentiate slow flow from mural thrombus in aortic diseases, we reviewed the spin-echo MR images of 13 patients with intraaortic thrombus documented by CT (N=11) or aortography (N=2). Six patients had aortic aneurysms and seven had aortic dissection. Intraaortic mural thrombi were accompanied by flow-related intraluminal signal of various patterns and extents in all 13 patients. On 10 gated MR studies, slow flow regions showed even-echo rephasing phenomenon (N=8), interslice variation of signal intensities of the intraluminal signal (N=7) and flow-related ghost artifact (N=2). However, these MR flow phenomena were obscured on two of three non-gated studies. Seven of 13 intraaortic thrombi remained hyperintense on T2-weighted second-echo images. In these circumstances, a hypointense boundary layer between slow flow and mural thrombus, which was caused by either 'boundary layer dephasing phenomenon' of slow flow or 'paramagnetic T2 shortening' of fresh clot at the edge of mural thrombus, was useful in discriminating the area of slow flow from that of mural thrombus. Proper interpretation of spin-echo MR images may obviate the need for phase display imaging or gradientecho imaging in differentiating slow flow and mural thrombus.

Bartter's syndrome is a rare tubular disorder characterized by hypokalemic, hypochloremic metabolic alkalosis, hyperreninemic, hyperaldosteronism, hyporesponsiveness to pressor agents and juxtaglomerular apparatus heperplasia. We report a case of Bartter's syndrome of a 5 month-old male infant with subdural hematoma who was confirmed by characteristic clinical, laboratory findings and kidney biopsy.
