N/A Objectives : We conducted our study to establish the mean values of total serum cholesterol in healthy Korean male adults and find out the relationship between the cholesterol levels and life styles(eg. smoking and drinking habits). Methods: Eight hundred seventy-nine men involved in a health screening program in May, 1992, in Kyungpook University Hospital, were studied. The total cholesterol levels are determined by enzymatic method. And the life styles of the study groups were examined by answering written questionnaires. Results: The mean value of total cholesterol 189.6±30.6 mg/dl. The total cholesterol levels are higher in the age groups of fourth and fifth decades than in the age groups of second and third decades. The cholesterol levels show the tendency to increase according to age. The cholesterol levels are 189.8±30.7 mg/dl in smokers and 189.0±30.6 mg/dl in nonsmokers. They are not statistically different in either group. But heavy smokers who smoke more than 20 cigarettes per day have higher total cholesterol values than non-smokers. The cholesterol levels are 19431.0 mg/dl in heavy drinkers who drink alcoholic beverages 3-4 times per week and 187.2±31.7 mg/dl in non-drinkers. The group who are both heavy smoker and drinker have significantly higher cholesterol levels than in the group who do not smoke and drink alcoholic beverage. The cholesterol levels in the former and in the latter group are !?0629.0 mg/dl and 18331.2 mg/dl, respectively. Conclusion : The total cholesterol values somewhat related to the age and the life styles such as smoking and alcohol consumption. Generally speaking, the more increased levels of total cholesterol is shown when the person is getting older, the amounts of cigarettes smoked are increased and the frequencies of alcoholic drinks are increased.

N/A mg/dl) in men and women was 36.8 and 44.0%, respectively and that of high LDL-cholesterol(≥160 mg/dl) was 26.6% in men and 35.2% in women. Their frequencies were increased with age in both sexes. 4) There were no significant, differences in the mean values of total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol and atherogenic index by residency. The frequency of high total cholesterol(≥200mg/dl) in Taegu and its rural area was 40.7% and 35.5%, respectively. Conclusion: These findings suggest that the mean concentrations of total cholesterol, triglyceride and LDL-cholesterol in men and women vary with age. The frequency of hypercholesterolemia (≥200 mg/dl) in men and women was about 40%, and increased with age. Values of HDL-cholesterol were not affected by age and sex

신경섬유종증 환자에서 갈색세포종이 동반된 경우는 약 0.1~5.7%에 이르나, 자발성 뇌출혈은 매우 드문 합병증이다. 저자들은 신경섬유종증 1형의 임상적인 특징을 보이는 30세 여자가 고혈압과 자발성 뇌출혈로 내원하였고 항고혈압제로 혈압이 조절되지 않아 뒤늦게 갈색세포종이 진단되어 수술적으로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Spontaneous intracerebral hemorrhage is very rare in patients with neurofibromatosis type 1. A 30-year-old woman was referred to our hospital for evaluation of headaches, nausea, and vomiting. She was diagnosed with neurofibromatosis type 1 and a spontaneous intracerebral hemorrhage. She was treated with conservative management, including antihypertensive medications for 32 months. However, because of sustained hypertension, we performed screening tests for a pheochromocytoma. The 24 hr urine VMA and urine metanephrines were elevated. Abdominal CT showed a right adrenal mass, 7.5×5.8 cm in size. After a successful resection of the tumor, the hypertension resolved without medication for >1year. This case illustrates that delayed diagnosis and treatment of pheochromocytoma can cause serious complications from hypertension, such as cerebrovascular hemorrhage. Thus, in patients with neurofibromatosis and hypertension, screening for pheochromocytoma is important for the early detection of an adrenal tumor. (Korean J Med 75:103-107, 2008)

Objective: To determine the correlation between total anti-oxidant capacity (TAOC) and lipid peroxidase (LPO) levels in serum and disease activity in systemic lupus erythematosus (SLE). Methods: The study population consisted of 99 patients with SLE according to the 1982 revised ACR criteria and 83 healthy controls. The serum TAOC levels in 99 patients with SLE and 83 healthy controls by the ABTS(R) inhibition method (Randox Ltd, Antrim, UK) and serum malondialdehyde (MDA) levels in 37 out of 99 patients with SLE were measured. Anti-dsDNA antibody (anti-dsDNA), albumin, AST, ALT, cholesterol, uric acid and creatinine were measured to determine the association with the serum TAOC levels. The correlation between the serum TAOC levels and nephritis in 27 cases with nephritis out of 99 SLE patients was also investigated. The SLE disease activity was determined by the SLE disease activity index (SLEDAI) at the time of sample collection. Results: Compared to the controls (1.37±0.127mmol/L), serum TAOC levels were significantly decreased (1.29±0.124mmol/L) in SLE patients (p=0.001). And there was a negative correlation between serum TAOC levels and SLEDAI total scores in the SLE patients (r=-0.388, p=0.0001), but no significant correlation between TAOC levels and C3 and anti-dsDNA. Further, a significant difference (p<0.04) in TAOC levels was found in SLE patients with and without nephritis. In comparison with other parameters such as AST, ALT, and cholesterol which might change anti-oxidant level, there was no correlation between the serum TAOC levels and them, except for serum uric acid (r=0.387, p=0.0001), creatinine, and albumin (r=0.507, p=0.0001). Additionally, we couldn`t find significant correlation between the serum TAOC levels and MDA. Conclusions: The serum TAOC levels correlate significantly with SLE disease activity and are associated with nephritis. Also, this study showed a significant correlation with serum albumin levels in these patients. Conclusively, the measurement of the serum TAOC levels in patients with SLE will provide useful information on SLE disease activity.

Catastrophic antiphospholipid syndrome is a rare clinical syndrome characterized by acute multi-organ failure occurring in patients with antiphospholipid antibodies. It is associated with involvement of several end-organs particularly kidneys, lungs, gastrointestinal tracts and adrenal glands and presents catastrophic clinical pictures such as acute renal failure with thrombotic microangiopathy, myocardial failure, adult respiratory distress syndrome, convulsion and disseminated intravascular coagulation. Conventional treatments(e.g. intravenous heparin, steroid, immunosuppressants) were not effective, while plasmapheresis seems to be a useful therapy. We experienced a case of catastrophic primary antiphospholipid syndrome in 41-year-old woman proved by renal biopsy and immuno-serological tests. She developed acute renal failure, multiple esophageal and oral ulcers, adult respiratory distress syndrome, abnormal elevation of hepatic and pancreatic enzymes and signs of disseminated intravascular coagulation. Evidences of any other connective tissue diseases were not found. Renal biopsy revealed features of thrombotic microangiopathic nephropathy and serum antiphospholipid antibody level was elevated(34GPL). In spite of steroid, cyclophosphamide and supportive therapies, her respiratory distress was not improved.

박헌식,김진년,정의룡,류재근,이봉렬,조용근,채성철,전재은,박의현 慶北大學校 醫科大學 1995 慶北醫大誌 Vol.36 No.4

목적 : 근래에 와서 ACE 길항제가 고혈압 및 심부전 환자들에게 널리 사용되면서 임상에서 기침 때문에 사용이 제한되는 경우를 흔히 접하게 된다. 따라서 ACE 길항제의 주요 부작용인 기침에 관한 연구를 시행하였다. 대상 및 방법 : 대상은 1990년 1월부터 1994년 6월까지 경북대학교병원 순환기내과에서captopril과 enalapril을 복용하고 있는 남자 45례, 여자 63례로 모두 108례였고 이들의 평균연령은 57±11.2세였으며 63례에서 captopril을 복용하였고 45례에서 enalapril을 복용하였다. 이들에서 기침의 발생과 환자의 임상적 경과는 병력지에서 관찰하였고 대상환자중에 호흡기질환이 있는 경우는 제외하였다. 결과 : 1) ACE 길항제를 사용한 108례의 환자중 27례에서 기침이 발생하였으며(25%) 그 중captopril을 사용한 환자에서는 28.5%이고 enalapril을 사용한 환자에서는 20%였으나 양군간에 통계학적으로 유의한 차이는 없었다. 2) 투약후 기침이 발생한 때까지의 기간은 평균 225±256.7일이었고 투약후 대개 6개월이내에 기침이 발생하였으며 1년이 지나서도 5명에게서 기침이 발생하였다. 3) 기침의 발생빈도는 심부전환자군이 34.4%, 고혈압환자군에서 20.5%였다. 4) 기침의 발생빈도는 여자에서 28.5%, 남자에서 20%이였으나 통계학적으로 유의한 차이는 없었다. 5) 연령에 따른 기침발생율은 차이가 없었다. 6) 흡연여부에 따른 기침발생율은 차이가 없었다. 결론 : 기침은 ACE 길항제의 흔한 부작용이며 고혈압이나 심부전 환자에서 ACE 길항제를 사용할 때에는 기침의 발생에 적절한 주의가 필요하다. Background : Angiotensin converting enzyme inhibitors(ACEI) are increasingly being used to treat hypertension and congestive heart failure. In general, these durgs are well tolerated, but an unexpected and troublesome cough has been reported in patients taking captopril or enalapril. We studied the incidence and characteristics of ACEI induced cough. Method I Medical records of patients who were treated for hypertension and congestive heart failure in division of cardiology were reviewed retrospectively. Excluding patients with respiratory disease, 108 patients on either captopril(n = 63) or enalapril(n = 45) were selected(45 males and 63 females). Their mean age was 57±11.2 years. Seventy three cases used ACEI for hypertension and thirty five for congestive heart failure. Results : Twenty-five percent of 108 patients(n = 27) developed a cough(cough group) after the ACEI medication(28.5% for captopril vs 20% for enalapril : not significant). Mean duration of therapy until the cough developed was 225 days. The incidence of the cough was 34.4% in patients with congestive heart failure and 20.5% in patients with hypertension (not significant). There was no difference in age between the cough group and the non-cough group(56±9.5 years vs 57±12.4 years). The cough did not appear to be related to the dosage of medications and smoking habits. Conclusion : A cough is not an uncommon side effect in patients taking ACEI. Optimal clinical application of ACEI in the treatment of hypertension and congestive heart failure will require increased awareness of the cough.

목적 : 동맥경화발생과 고지혈증과의 관계에 관한 연구로 최근에는 혈청지질의 분석외에 apolipoproteins에 관심이 증가되고 있지만 우리나라에서는 이 방면에 관한 연구가 별로 없는 상태이어서 본 연구를 하였다. 재료 및 방법 : 급성심근경색환자 31례와 성인병당뇨병환자 37례에서 몇가지 혈청지질과 apolipoprptein A1 및 B를 측정하여 건강인 36례의 성적과 비교, 검토하였다. 결과 : 1) 총 cholesterol, triglycerides, LDL-cholesterol 및 apolipoprptein B는 대조군에 비해 급성심근경색환자 및 당뇨병환자에서 유의하게 높았다. 2) HDL-cholesterol/총 cholesterol비 와 LDL-cholesterol/HDL-cholesterol비는 급성심근경색환자군에서만 각각 유의하게 감소 및 증가하였다. 총 cholesterol/Apo-B비와 Apo-A1/Apo-B비는 급성심근경색 및 당뇨병환자군 모두에서 대조군에 비해 유의하게 낮았다. 3) Apolipoprptein B는 총 cholesterol, triglycerides, LDL-cholesterol과 유의한 양의 상관이 있었으나 apolipoprptein A1은 그러하지 않았다. 4) 총 cholesterol이 200㎎/㎗미만인 급성심근경색환자에서는 대조군에 비해 여러지질치 가운데 apolipoprptein B만 유의하게 높았다. 결론 : 이상의 성적으로 보아 apolipoprptein B는 혈청지질중 특히 총 cholesterol, LDL-cholesterol과 유의한 상관이 있었으며 급성심근경색 및 당뇨병환자 모두에서 유의하게 높았다. In recent years, the studies of the relationship between coronary atherosclerosis and hyperlipidemia were focused upon analysis of apolipoproteins including serum lipids. However there were a few reports regarding to this field in Korea. We measered the levels of serum lipids and apolipoprotein A1 and B in 31 patients with acute myocardial infarction and 37 diabetics and compared the results with those in 36 healthy controls. The results were as follows'. Compared with the healthy controls, serum concentrations of total cholesterol, triglycerides, LDL-cholesterol and apolipoprotein B were significantly higher in patients with acute myocardial infarction and diabetics. Ratio of HDL-cholesterol/total cholesterol was significantly lower in pateints with acute myocardial infaction. Ratio of LDL-cholesterol/total cholesterol was significantly higher in patients with acute myocardial infarction. Patients with acute myocardial infarction and diabetics had a lower ratio of total cholesterol/Apo-B and Apo-A1/Apo-B. Level of apolipoprotein B was significantly higher in patients with acute myocardial infarction whose total cholesterol value were under 200 ㎎/㎗ than in controls. Apolipoprotein B was correlated significantly with LDL-cholesterol, total cholesterol and triglycerides but apolipoprotein A1 was not.
