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.

Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.

During 1 year and 9 month period, from September, 1980 to June, 1983, retrospective study was performed on 35 patients with Mitral Valve Prolapse at Kyung Hee University Medical Center. And the following results were obtained; 1) The mitral valve prolapse syndrome presents with various cardiovascular symptoms including dyspnea(63%), palpitation(49%), chest pain(34%), syncope and dizziness(11%). 2) Of 35 patients with MVP, 17 cases were isolated MVP, 13 cases were associated with cardiovascular disorders and 5 cases were associated with non-cardiovascular disorders. 3) Electrocardiographic abnormalities were found in 20 patients with MVP. The most common abnormality was ST-T change and atrial fibrillation, VPB, RBBB, first degree A-V block and W-P-W syndrome were also noted. 4) QTc interval prolongation was more common in serverely symptomatic patients with MVP. 5) 18 cases in 35 patients showed systolic click or murmur on phonocardiography. 6) Of 35 patients with MVP, 19 patients demonstrated prolapse of the anterior leaflet, 11 patients demonstrated prolapse of posterior leaflet and 5 patients demonstrated prolapse of the both leaflets. 7) There were severe derangement on echocardiography in severely symptomatic patients were MVP.

Stress distribution on mandibular implants supporting overdentures were registered in vitro experimental model by means of 4 rosette gauges which were placed around the implant. The overdenture attachments used in this study were the Resilient Dolder bar, Rigid Dolder bar, Round bar, Hader bar&Dal-Ro attachment. An occlusal jig was placed on the overdenture and the loading sites were 3 points which mimicked working, balancing, and median relations. With 5 and 10kg loading, strains were measured by strain indicator(P-3500, Measurement group, Raleigh, USA), and using these data, maximum and minimum principal stresses and Von Mises stress were calculated and evaluated. The results were as follows: There was a tendency of high stress concentration in the lingual side of the implant, and in the buccal side low stress was developed regardless of the attachment systems. The resilient Dolder bar concentrated highest stress among the attachment systems, and the Round bar and the Dal-Ro attachment provided comparatively low stresses around the implant. The rigid Dolder bar concentrated high stress in the mesial side, and the Dal-Ro attachment developed tensile stress patterns in the lingual and distal sides of the implant at the balancing relation.

BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

Aortic root diameter by two dimensional and M-mode echocardiography in predicting prosthetic aortic valve size preoperatively was measured in 10 adult patients undergoing aortic valve replacement. Correlation of aortic root diameter measured by two dimensional echocardiography and actual prosthetic valve size implanted by aortic valve replacement was excellent. Correlation coefficient was statistically significant (r=0.91, P<0.001). Correlation of aortic root diameter measured by M-mode echocardiography and actual prosthetic valve size was also excellent. Correlation coefficient was statistically significant (r=0.86, P<0.001). This study demonstrates that aortic root diameter by two dimensional and M-mode echocardiography can accurately predict prosthetic aortic valve size in patient undergoing aortic valve replacement.
