Measurements of mitral flow velocity by pulsed Doppler echocardiography are very useful in evaluating left ventricular diastolic filling properties. In hypertensive patients, abnormalities of diastolic function may precede systolic abnormalities and may serve as a more sensitive marker of end organ damage. We estimated left ventricular nass by 2-D echo short axis area-length method and compared with peak mitral flow velocity in early diastole(PFVE)and during atrial systolic(PFVA). There was a significant increase of LV mass and LV mass indices in the hypertensive patients and PFVE/PFVA ratio was decreased in them. Aithough there was no relationship between blood pressure and PFVE/PFVA ratio, a significant relationship was demonstrated between LV mass index and PFVE/PFVA ratio in the hypertensive patients.

Early and longterm prognosis depended on the extents of acute myocardial infarction and residual myocardial function. Many clinical methods have been evaluated to determine their ability to estimate the size of myocardial infarcts. But because of many disadvantages simplified QRS scoring system, used with standard 12-lead EKG, was developed, which is noninvasive, inexpensive and easily releatible. Therefore, the correlation between QRS and peak CK,killip classification were evaluated in 55 patients with initial acute myocardial infarction at the Chung-Ang University, Yong-San and Pil-Dong Hospital during the period from January 1983 to December, 1986. The results were as follows : 1) The average QRS score of the anterior wall infarction is 7.1 and that of the inferior wall infarction is 4.5 and there is a statistical significance(p<0.01). 2) In the acute myocardial infarction, the correlation coefficeient between the QRS score and the killip classification is 0.66(p<0.05). 3) In the acute myocardial infarction, the average QRS score is 6.3 and the correlation coefficient between the leak CK and the QRS score is 0.52(p<0.05). 4) In the anterior wall infarction, the average QRS score is 7.1 and the correlation coefficient between the peak Ck and QRS score is 0.48(p<0.05). 5) In the inferior wall infarction, the average QRS score is a 4.5 and the correlation coefficient between the leak CK and QRS score is 0.79(p<0.05).

4.Mounting and utilization of provisional prostheses on master cast for the fabrication of fixed implant-supported prostheses: a case report
The Journal of Korean Academy of Prosthodontics 2024;62(4):349-356
The restoration process for patients with collapsed occlusion or those requiring extensive rehabilitation often involves various trials and errors. Accurately transferring the patient’s oral information to the articulator is key to producing esthetically pleasing and stable prostheses. This necessitates precise master model fabrication and accurate jaw relation records. For patients undergoing extensive implant-supported fixed prostheses, several techniques for recording the jaw relationship are available, including the use of record bases with wax rims, bite blocks with temporary abutments and pattern resin, or provisional prostheses.Among these, using provisional prostheses directly for mounting on the master model can help minimize errors during the jaw relation recording phase. The patient in this case was a 55-year-old female patient, who presented for implant-supported fixed prosthetic rehabilitation. She exhibited multiple tooth loss due to periodontal disease, necessitating comprehensive mouth rehabilitation involving extractions and implant placements. After evaluating esthetics and occlusion with provisional prostheses, the same provisional prostheses were used for mounting on the master model, which enabled the fabrication of customized implant abutments and zirconia prostheses. The final result was a successful restoration, both esthetically and functionally.

PURPOSE: The purpose of this study was to review our clinical experiences of acute mesenteric ischemic disease at the Masan Samsung hospital. METHOD: Retrospectively reviewed the medical records of 20 patients with acute mesenteric ischemic disease from 1998 through 2003 in terms of clinical characteristics, image findings, management and results. RESULT: The mean age of patients was 63.5 years and the male female ratio was 1.5:1. Coexisting diseases were atrial fibrillation (n=10), hypertension (n=9), myocardial infarction (n=2), DM (n=4). The clinical manifestations were abdominal pain, abdominal distension, peritoneal irritation signs, vomiting and melena. The presenting signs were nonspecific. Laboratory findings were nonspecific and not helpful for diagnosis of acute mesenteric ischemia. Abdominal CT and SMA angiography were accurate and sensitive diagnostic tools. Seventeen cases were SMA occlusion (1 case: SMA dissection) and 3 cases were SMV occlusion. Operative procedures were resection of bowel (12 cases) and thromboembolectomy (5 cases). Non operative procedure was anticoagulation (3 cases). One patient refused surgery. CONCLUSION: Both clinical and laboratory data were non-specific and delayed diagnosis was the main cause of the overall mortality rate of 35% (7 cases). The mortality rate for patients undergoing surgery for acute mesenteric ischemic disease was high, but early diagnosis and intensive care may be reduced mortality.

Clinical observarions were done on 616 cases of cerebrovasculae accidents treated as inpatients at the Sung-Sim hospital, Chung-Ang university over a period of 8 years, from January, 1981 to Agust, 1988. The results were as follows; 1) Of 616 cases of cerebrovascular accidents, cerebral hemorrhage was presented in 56.82%, cerebral thrombosis in 28.57%, subarachnoid hemorrhage in 12.66%, cerebral embolism in 1.95%. 2) The ratio of male to female was 1.01:1. 3) The cerebrovascular accidents were most common in the sixth decade and followed by the fifth and fourth in turn. 4) The seasonal incidence was in order of frequency of Spring, Winter, Autumn and Summer. 5) Among disease preceding the onset of cerebrovascular accidents, hypertension was noted at 75% in cases of cerebral hemorrhge, 61% in cerebral thrombosis and 73% in subarachnoid hemorrhge. 6) The mean duration of underlying hypertension was 13.7 years in cerebral emorrhge, 15.3 years in cerebral thrombosis, 12.2 years in subarachnoid hemorrhage and 14.8 years in cerebral embolism. 7) Major precipitating factor in cerebral hemorrhage and subarachnoid hemorrhage was thought to be physical activity, whereas cerebral thrombosis and cerebral embolism frequently occured during sleeping or resting state. 8) The mean cholesterol level were 204.1mg% in cerebral hemorrhage, 214.9mg% in cerebral thrombosis, 211.7mg% in subaraachnoid hemorrhage and 217.0mg% in cerebral embolism. 9) The mortality rate was 12.2% in total, 16.6% in cerebral hemorrhage 2.3% in cerebral thrombosis, 15.45 in subarachnoid hemorrhage and 25% in cerebral embolism.
