Isolated and severe left main coronary ostial stenosis is a rare case. In the majority of these patients ostial stenosis was associated with any of the conditions known to involve the coronary ostia. These conditions include syphilitic aortitis, Takayasu's aortitis, familial hypercholesterolemia, and aortic valve disease. A 34-year young female patient was presented with exertional and stabbing anterior chest pain. There was no history of syphilis, diabetes mellitus, hypertension, hyperlipidemia and smoking. Coronary angiogram showed isolated left main coronary ostial stenosis. Transesophageal echocardiography(TEE) showed acute angle takeoff of the left main coronary artery. She underwent surgical angioplasty of coronary ostia with a patch of autologous pericardium. After angioplasty, TEE showed dilatation of left main coronary ostium and her clinical symptom improved.

In order to review the epidemiological data of cardiovascular diseases, statistical observation was made on the 7,271 patients with cardiovascular diseases who were treated in the Department of Internal Medicine, Han-Yang University Hospital during the 10 year period from May 1972 to December 1981. A. General Findings (1) Cardiovascular disease was seen in 18.6% out of a total 39,004 medical inpatients treated during this 10 year time span. (2) Incidences of cardiovascular disease seemed to increase in frequency in consecutive years, especially incidence of coronary heart disease and arrhythmia. (3) Incidence of cardiovascular disease occurred most frequently to patients in their fifth decade, and next most frequently to those in their sixth and fourth decade, in that order. (4) The overall ratio of male to female incidence of cardiovascular disease was 1:1. B. Specific Epidemiology (1) Hypertension was the most common form of cardiovascular problem, accounting for 52.9% of patients with cardiovascular disease and 9.9% of the total medical in-patients population. Incidence of hypertension occured most frequently in the fifth decade of life. It occured next most in the sixth and fourth decades, in that order. The male to female ratio of incidence of hypertension was 1:1. Patients with malignant hypertension made up 5.9% all hypertension patients. (2) Patients with rheumatic heart disease made up 6% of those patients with cardiovascular diseases. Male to female ratio of incidence of rheumatic heart disease was 1:2.4. The most common form of this disease was mitral valvular disease, but isolated aortic valvular disease proved to be rather uncommon in this study in Korea. (3) Coronary heart disease made up 15.5 % of all incidence of cardiovascular diseases. It occured most frequently to patients in their fifth and sixth decades, and in a male to female ratio of 1.5 to 1. (4) Congenital heart disease made of 0.9% of the total incidence of cardiovascular diseases with ventricular septal defect as the most common form of this disease. (5) The remaining forms of cardiovascular diseases diagnosed during the time span of this study were arrhythmia 16.8%, cor pulmonale 1.4%, cardiomyopathy 1.3%, peripheral vascular disease 1.0%, pericarditis 1.0%, thyrotoxic heart disease 0.8%, endocarditis 0.5%, postpartum cardiomyopathy 0.3%, myxedematous heart disease 0.1%, and miscellaneous heart ailments 1.5%.

Several bills were proposed during the 20th and 21st National Assemblies to grant special judicial police powers to employees of the National Health Insurance Corporation (NHIC) to improve the low recovery rate of unfair profits collected by non-medical practitioner hospitals. The Ministry of Health and Welfare made a pre-announcement of legislation regarding the revision of the Enforcement Decree of the Medical Law, aiming to delegate certain enforcement responsibilities, including investigations into illegally established hospitals. This study discusses the contents and issues related to the bill, focusing on the revision of the Enforcement Decree of Medical Law and the bill proposed by the 21st National Assembly. Furthermore, it proposes improvements to address the challenges posed by non-medical practitioner hospitals.Current Concepts: We pointed out concerns regarding the bill to grant special judicial police powers to NHIC employees, such as the potential infringement of basic rights due to a lack of expertise among these special judicial police, a reversal of procedural thinking, challenges in identifying illegal hospitals, the appropriateness of granting investigative rights to NHIC employees, and the risk of abuse of these rights.Discussion and Conclusion: We propose strengthening the establishment, operations, and supervision of medical corporations; introducing a preliminary monitoring system for the establishment of medical institutions through branches of medical personnel organizations; and implementing a leniency program.

OBJECTIVE: to investigate the effect of high glucose and spent peritoneal dialysate on the TGF-beta1 synthesis of cultured human peritoneal MC(HPMC); to examine the effect of costimulation with high glucose or dialysate and cytokines, interleukin-1beta(IL-1beta) and tumor necrosis factor-alpha(TNF-alpha), on transforming growth factor(TGF-beta1) synthesis of HPMC. DISIGN: HPMCs were exposed to different concentrations of glucose(30, 60 & 90 mM/L) or spent peritoneal dialysate for 48 hours in the absence or presence of IL-1beta(1ng/ml) and TNF-alpha(1ng/ml). TGF-beta1 mRNA expression was assessed by Northern blot analysis and TGF-beta1 protein synthesis and release by Western blot analysis with immunoprecipitation. RESULTS: Exposure of MC to high glucose condition(30mM, 60mM & 90mM of D- glucose) induced 2.3-, 3.6- and 4.0-fold increases in TGF-beta1 mRNA expression of MC with enhanced TGF-beta1 protein synthesis and secretion into the media. Incubation with spent dialysate also significantly increased TGF-beta1 mRNA expression & protein secretion compared to control media(P<0.05) Stimulation with IL-1beta(1ng/ml) or TNF-alpha(1ng/ml) significantly increased TGF-beta1 mRNA expression after 48 hours above the control level by 2.7-fold and 2.1-fold, respectively. However, TNF-alpha-induced increase in TGF-beta1 mRNA expression was not translated into TGF-beta1 protein secretion whereas IL-1beta stimulation induced a significant increase in TGF-beta1 protein secretion as well as TGF-beta1 mRNA expression. Combined stimulation of high glucose or spent dialysate together with IL-1beta or TNF-alpha showed a greater increase in TGF-beta1 mRNA expression and protein secretion compared to stimulation with high glucose or spent dialysate alone. CONCLUSION: Our results clearly show that high glucose concentration of peritoneal dialysate and spent dialysate themselves might be sufficient to stimulate the production of TGF-beta1 by peritoneal mesothelial cell. This state of chronic induction of TGF-beta1 is further exaggerated in the presence of peritonitis because of stimulatory effect of proinflammatory cytokines, resulting in the augmented TGF-beta1 synthesis, thus promoting peritoneal fibrosis.

PURPOSE: To evaluate the usefulness and radiologic findings of CT in the diagnosis of orbital blow-outfracture. MATERIALS AND METHODS: Forty-four patients with orbital blow-out fractures diagnosed by clinicalfindings and CT were evaluated retrospectively. On CT images, we evaluated the site and frequency of fracture,herniation of orbital fat, extraocular muscle abnormality, intraorbital hematoma, and intrasinus hemorrhage. RESULTS: Forty-eight sites of orbital wall fractures were seen. Of these, 25(52.1%) were observed at the medialwall and 18(37.5%) at the inferior wall. Combined fracture of the medial and inferior wall was seen in fivecases(10.4%), and orbital fat herniation to adjacent sinuses in 25. Associated extraocular muscle abnormalitieswere seen at the medial rectus (n=20) and inferior rectus muscle(n=18). Intrasinus hemorrhage was seen in 15cases, and intraorbital hematoma in five. CONCLUSION: CT is a useful diagnostic modality for the evaluation oforbital blow-out fracture and associated soft tissue abnormalities.

The hypotensive effect and side reactions of captopril (combination with hydrochlorthiazide in some cases) were evaluated in 42 patients with essential hypertension. The results were as follows: 1) Before medication and after 2, 4, 6, 8 and 10 weeks of medication, the over all average systolic & diastolic pressure were 178.2+/-42.6/111.3+/-21.1, 150.6+/-36.2/95.2+/-34.5, 140.3+/-31.4/93.6+/-24.3, 135.6+/-28.6/90.6+/-17.1, 130.9+/-20.5/87.9+/-16.4, 128.7+/-24.0/86.4+/-15.3mmHg respectively. After 10 weeks of medication, marked or moderate degree of hypotensive effect was observed in 98% of all cases (systolic pressure), 93% of all cases (diastolic pressure)(P<0.001, P<0.001). 2) There was no significant changes in heart rates before and after treatment. 3) There was no side effects which required discontinuing the medication, decreasing the dose or other treatment for side effects.
