We studied 105 patients with trasmural myocardial infarction who were admitted to Soonchunhyang university hospital from 1984-1988, and evaluated the clinical and coronary angiographic findings accordin to the age. The following results were obtained: 1) Among 105 patients with myocardial infarction, the prevalent age were sixth and seventh decade(27.6%) and the ration of male to female was 2:1, But the raion of male to female was 5.3:1 under the 50 years of age. 2) In frequency of risk factor of coronarhy heart disease, cigarrette smoking was present in 66.7%, hypertensio in 44.8% and hypercholesterolemia in 28.6%. The mean number of risk factor was 1.3 under the 50 years of age and was 1.7 over the 50 years of age. 3) Anterior myocardial infarction was most common under 50 years of age whereas anterior and inferior myocardial infarction occur similarly over the 50 years of age. 4) By coronary angiography, one vessel disease of stenosis of left anterior descending coronary artery was common findings under 50 years of age, but multivessel disease was common findings over the 50 years of age.

The present study was performed to provide an anatomical basis of the coracoacromial (CA) arch and the articular surfaces of the scapula which can be applied to the diagnosis and treatment of some common shoulder problems. The standard dimensions and the range of variation of the CA arch, the acromial articular surface and the glenoid cavity were investigated in 114 dry scapulae obtained from 57 (male, 35 ; female, 22) Korean cadavers ranging in age from 18 to 97 years (average age of 67). The results were as follows : 1. The length (46.3mm), width(25.2mm), thickness (8.2mm) and height (4.5mm) of the acromion were measured. The length, width and thickness were significantly larger in the males. The slope of the acromion was 51.5°, and the slope of the scapular spine was 118.5°. 2. The height (13.5mm), slope of the root (138.4°) and the horizontal part (25.3°) of the coracoid process, and the angle between the root and the horizontal part (106.6°) were measured. There were no significant differences between sexes and sides in all morphometric values related to the coracoid process. 3. The length (67.6mm) and height (24.7mm) of the CA arch, the height of the CA ligament from the supraglenoid tubercle (13.1mm), and length of the CA ligament (27.6mm) were measured. Both the length and height of the CA arch and the length of the CA ligament were significantly larger in the males. The slope and anterior and posterior angles of the CA arch were 16.8°, 42.2°, and 34.7°, respectively. 4. The long (13.8mm) and short (8.0mm) diameters of the acromial articular surface were measured, and both diameters were significantly longer in the males. The acromial articular surface was 8.4mm away from the tip of the acromion and extended 1.4mm inferiorly below the inferior surface of the acromion. 5. The long (34.8mm) diameter, and superior (15.0mm), middle (19.5mm), and inferior (25.6mm) short diameters of the glenoid cavity were measured. The long and both superior and inferior short diameters were significantly longer in the males.

BACKGROUND/AIMS: The optimal time point for initiating renal replacement therapy in patients with end-stage renal disease remains controversial. The primary objective of our study was to determine the effects of residual renal function at the beginning of renal replacement therapy on the mortality of patients with end-stage renal disease. METHODS: We retrospectively studied the clinical outcomes in patients (n=210) with end-stage renal disease who underwent renal replacement therapy at our hospital between 2000 and 2005; all patients were followed for more than 1 year. We used the Modification of Diet in Renal Disease equation to estimate residual renal function. RESULTS: Of the 210 patients who received renal replacement therapy, 108 were treated with hemodialysis and 102 were treated with peritoneal dialysis. Thirty-three patients died, and the mean survival period was 37.3+/-17.7 months. The survival rates were compared based on the estimated glomerular filtration rate; no difference in survival rates was observed (p=0.27). Subgroup analysis in the hemodialysis group showed that patients who began chronic dialysis at a lower estimated glomerular filtration rate had higher mortality rates (p<0.05); patients treated with peritoneal dialysis showed no significant difference in mortality rate (p=0.50). CONCLUSIONS: Although there was no difference in the mortality rate based on residual renal function, hemodialysis patients with a lower estimated glomerular filtration rate showed a higher mortality rate than those with a higher estimated glomerular filtration rate.

Endometriosis in the abdominal wall following Cesarean section is one of the very rare condition among the extrapelvic endometriosis. Although benign, endometriosis possesses the unique ability to invade tissue and to disseminate or metastasize by hematogeneous, lymphatic route, or direct implantation. We reported the case with brief review of the literature.

PURPOSE: Genes involved in liver cancer cell growth have been identified using an antisense library of large circular (LC-) genomic DNA of a recombinant M13 phage. MATERIALS AND METHODS: A subtracted cDNA library was constructed by combining procedures of suppression subtractive hybridization (SSH) and unidirectional cloning of the subtracted cDNA into an M13 phagemid vector. Utilizing the life cycle of M13 bacteriophages, LC-antisense molecules derived from 1, 200 random cDNA clones selected by size were prepared from the culture supernatant of bacterial transformants. The antisense molecules were arrayed for transfection on 96-well plates preseeded with HepG2. RESULTS: When examined for growth inhibition after antisense transfection, 153 out of 1, 200 LC-antisense molecules showed varying degrees of growth inhibitory effect to HepG2 cells. Sequence comparison of the 153 clones identified 58 unique genes. The observations were further extended by other cell-based assays. CONCLUSION: These results suggest that the LC-antisense library offers potential for unique high-throughput screening to find genes involved in a specific biological function, and may prove to be an effective target validation system for gene-based drug discovery.

From July, 1992 to June, 1993, 32 patients with BPH were treated with transurethral radio frequency thermotherapy(TURT) and 54 patients with transurethral microwave thermotherapy (TUMT). Of the patients 15 and 19 were followed for 3 month(range 2-6 months) and analysed to compare the effectiveness of TURT and TUMT respectively. Mean age was 70.3(range 55-88) and 68.7( 54-82) and mean prostatic weight was 30.3gm ( 14-52gm) and 33.8gm(11 -60gm). These patients were treated by one session for 1 hour. The improved response rate with TURT versus TUMT in residual urine volume and maximal flow rate were 40%, 57% and 47%, 32%. The improved response rate more than 6 points in modified Boyarsky symptom score were 73% and 63%. The side effects were urinary retention, dysuria, hematuria and perineal discomfort in both types. We conclude there were no differences in the effectiveness according to electromagnetic wave types and these transurethral thermotherapies are safe and simple method for patients who are not candidates for surgery because of medical illness or personal favorites.

BACKGROUND: It is well known that intracoronary thrombolysis during the early period of acute myocardial infarction leads to the limitation of myocardial necrosis, preserves left ventricular function, and improves survivals. The recanalization rate of intracoronary rrokinase infusion into infarct-related coronary artery was known as 62-94 percents in previos studies. The various factors influence the outcome of intracoronary thrombolysis, including total dose of urokinase, time from onsrt of chest pain to thrombolysis. The purpose of this study was to evaluate whether the occlusion site morphology influences recanalization rates of intracoronary thrombolysis. METHODS: We evaluated infarct-related coronary artery morphology of 56 acute mycardial infarction patients who performed intracoronary thrombolytic therapy within 6-12 hours after the onset of acute myocardial infarction. Intracoronary urokinase infusion was performed at a rate of 25000 IU/minute. The presence of calcification, collaterals, side branches and the stump site morphologies(thrombus type, pencil type, cutting type) were identified on magnified 35mm cine frames. RESULTS: Reperfusion was successed in 34 patients and failed in 22 patients. There were no statistically significant difference in the pressure of calcification, collaterals, and side branches between success and failure groups. Intracoronary thrombus was identified in 21 percent of success group, but not in failure group. The reperfusion rates according to stump site morphology were 76% in thrombus type, 58% in cutting type, and 42% in pencil type(p<0.05). CONCLUSION: Our study indicates the presence of intracoronary thrombus and the morphology of thrombus type is more effective in intracoronary thrombolysis in acute myocardial infarction. The identification of types of the coronary obstruction will be helpful for the selection of intracoronary thrombolysis in acute myocardial infarction patients. And the results suggest that the difference of stump composition show different stump morphologies.

Pleomorphic xanthoastrocytoma(PXA) is a benign brain tumor with favorable prognosis in spite of its marked pleomorphism. We report a case with review of the literature. An eight-year-old boy presented with headache and vomiting. Plain skull X-ray showed findings of increased intracranial pressure. The MR imaging demonstrated superficially located large cystic mass with a Iobulated mural nodule in the left frontal lobe. The mural nodule abutting leptomeninges showed intense enhancement on postcontrast Tl-weighted images, but the cyst wall was not enhanced. Preoperative diagnosis of PXA with the MRI findings could lead to avoidance of more aggressive brain resection and therefore more favorable neurological outcome

Endocrine adrenal tumors are uncommon but clinically significant because they can be managed successfully by surgical therapy. During pregnancy, adrenal tumors can be a cause of death for both mother and baby, unless they diagnoses antenatally and managed properly. To investigate clinical characteristics of endocrine adrenal tumors, we analyzed 26 cases of adrenal tumor diagnosed and managed in Chung Ang Gil Hospital including cases associated with pregnancy and also a rare case of paraganglioma in liver. 1) There were 7 cases of Cushing's syndrome among which two cases were due to Cushing's disease and five cases were due to adrenal adenoma. Six cases were managed successfully by appropriate surgery. Another one case was associated with pregnancy but the patient expired due to sudden development of pulmonary edema and hypotension during preoperative preparation.2) Among 9 cases of primary aldosteronism, 8 cases were aldosterone-producing adenoma(APA) and 1 case was idiopathic hyperaldosteronism(IHA). In differential diagnosis between APA and IHA, diagnostic accuracy of postural study and adrenal CT was 86%, 78% respectively. In each one case of APA and IHA, adrenal venous aldosterone sampling was used for the differential diagnosis. Six cases of APA were managed by appropriate surgery. One patient with APA who refuses surgery and one patient with IHA were placed on spironolactone with good response.3) Among 10 cases of pheochromocytoma, seven cases were from adrenal gland and three cases were paragangliomas including one case originating from liver and two cases from abdominal ganglia. One patient with pheochromocytoma was diagnosed in 1st trimester of pregnancy and she was successfully treated by surgery.We observed 26 cases of endocrine adrenal tumors which were successfully managed except one case. We think that it is important to pay attention to adrenal tumor for early diagnosis particulary when associated with pregnancy. Paraganglioma in liver, although very rare, should be included in the differential diagnosis of space occupying lesion in liver.
