BACKGROUND AND OBJECTIVES: There has been much need for standard normal values of echocardiographic indices in Korea. Echocardiography Council of the Korean Society of Circulation performed multicenter trial for estimation of normal values of echocardiographic indices. METHOD: In 19 university or general hospitals, echocardiographic specialists measured frequently used echocardiographic indices with the same method in healthy people. The measured indices were 36 items which involved M-mode, 2-dimensional and Doppler echocardiographic parameters. All the results were recorded on video tapes and reviewed by the review committee. The results were included for analysis only if the review committee accepted them. RESULTS: Total 371 healthy people were included. There were 189 women. Their age ranged from 3rd decades to 8th decades. Complete measurement of all the indices was done in 225 people. Left ventricular wall thickness, aorta size, left atrial size and left ventricular mass in M-mode echocardiographic measurement changed significantly with the increase of age(p<0.005). In 2-dimensional echocardiographic examination, sinotubular junction diameter of the aorta, anteroposterior & superoinferior diameters of left atrium, both ventricular outflow tract diameter and main pulmonary artery diameter changed with the increase of age(p<0.01). Diastolic dysfunction became prominent with the increase of age in Doppler examination. CONCLUSION: We conclude that these data could be used as the standard criteria for echocardiographic examination in Korea. However, age factor should be considered when they are applied because many echocardiographic indices change significantly with the increase of age.

The authors present seven cases of Democidiosis in rosacea type and the subject of human demodetic infestation has been reviewed. According to our experience, demodex folliculorum, although a normal inhabitant of the sebaceous glands in small numbers, when encouraged to multiply by the patients excessive use of facial cream and avoidance of soap, can produce democidiosis. The diagnosis was easily confirmed by characteristic clinical appearance and simple microscopy. The characteristie clinical appearances are indurated non-comedous papules and pustules with unique cherry pinkish red erythema. The response to treatment, consisting of daily soap and water cleansing of the face, followed by the local application of a suitable antiparasitic remedies is simple and gratifying. But the erythema was not respond to antiparasitic preparation.

BACKGROUND AND OBJECTIVES: Regular aerobic exercise plays a role in the prevention of cardiovascular diseases, but the risk of primary cardiac arrest transiently increases during vigorous exercise, particularly in sedentary men. There has been a controversy regarding the effect of exercise on platelet functional behavior, which is related to the pathogenesis of coronary ischemia. We evaluated the cytoplasmic free calcium concentration of platelets in healthy men after treadmill exercise. MATERIALS AND METHOD: Five physically active (group I: age, 24.2+/-2.3 years) and five sedentary men (group II: age, 22.4+/-1.4 years) were included in this study. Platelet calcium was measured with fluorescent dye, quin2 before and after treadmill exercise. RESULTS: Platelet calcium levels were increased from 86.8+/-11.8 nM to 128.8+/-15.0 nM in group I (p<0.05) and from 102.6+/-14.4 nM to 162.4+/-26.5 nM in group II (p<0.05) immediately after exercise. Thereafter, platelet calcium levels were decreased in group I, but continuously increased in group II. At fifteen minutes after exercise, platelet calcium concentrations were significantly higher than baseline values in group II (205.8+/-53.9 nM vs 102.6+/-14.4 nM: p<0.05), but not in group I (115.2+/-15.7 nM vs 86.8+/-11.8 nM). CONCLUSION: Cytoplasmic free calcium concentration in platelets were continuosly increased after treadmill exercise in sedentary men but not in physically active men.

BACKGROUND: Platelet function is directly influenced by lipoproteins, and platelets from hypercholesterolemic patients display increased reactivity which is related to initiation, progression, and development of thromboembolic complications in atherosclerosis. But the exact mechanism of this effect is unclear. METHODS: In this study, total and activated numbers of platelet glycoprotein (Gp) IIb/IIIa were evaluated in twenty patients (7 men; age, 55.4+/-8.7 years) with hypercholesterolemia (plasma total cholesterol level over 240 mg/dL and normal triglyceride level) and twenty one subjects (8 men; 51.1+/-13.7 years) with normal plasma cholesterol and triglyceride levels. Flow cytometry was used to detect the binding of fluorescein isothiocyanate (FITC)-conjugated anti-CD41 or PAC1 to platelet Gp IIb<1/4>/<1/4>IIIa in whole blood. When whole blood was incubated with PAC1, platelets were also activated with adenosine diphosphate (ADP) or thrombin. RESULTS: PAC1 was more bound to unstimulated platelets from patients with hypercholesterolemia (p<0.005), and binding of PAC1 correlated significantly with plasma total cholesteol (r=0.48, p=0.002) and LDL-cholesterol (r=0.47, p=0.002) levels. Binding of PAC1 to unstimulated platelets increased as binding of anti-CD41 increased (r=0.40, p=0.01). On multivariate linear regression analysis, plasma total cholesterol level and binding of anti-CD41 were independent variables that determined binding of PAC1. After ADP- or thrombin-stimulation, binding of PAC1 to platelets and percentage of antibody positive cells were also greater in patients with hypercholesterolemia (p<0.05). There was a significant positive correlation between mean platelet volume and binding of anti-CD41 to unstimulated platelets (r=0.46, p<0.0050), but the latter was not different between hypercholesterolemia and control groups. CONCLUSION: Unstimulated platelets from patients with hypercholesterolemia had similar total number of Gp IIb/IIIa to those from control subjects, but had more activated Gp IIb/IIIa. After ADP- or thrombin-stimulation, platelet Gp IIb/IIIa was also more activated under hypercholesterolemia.

Herpes zoster is generally believed to be caused by the activation of varicella-zoster virus present in the body since an original infection with varicella. According to the thesis, the virus remairis in a latent state in the cells of the sensory ganglia until immunity has waned sufficiently to pezmit multiplication of the virus and clinical infection. There are a number of reports that in patient with malignant disease, especially Jymphoma, a frequenry af association of zoster is greater and severity of its symptom is increased to be marked contrast to the benign uneventful course of zoster seen in healthy person. The author observed one case of zoster seen in patient with malignant disorder, and frequency of association of zoster in malignant disease and its etiological factors are reviewed in the literature.

The goal of fracture treatment is to restore the patient to pre-injury function level. But the outcome assessment after orthopedic interventions has usually focused on physician-defined parameters of technical success, such as fracture union, alignment and range of motion rather than patient function and quality of life. However, the correlation among improvements in these parameters and functional status, psychosocial well being is inconsistent and weak in the elderly. Therefore authors assessed the functional status after surgical intervention of hip fractures in the elderly with functional recovery score(FRS). Independence in basic activities of daily living, in instrumental activities of daily living, in mobility, freedom from pain and intact memory were assessed in 133 hip fractures in the elderly. The hip fractures in the elderly resulted in 24.8% loss of function after the first year. The older the age, the more the loss of function after surgery of hip fractures. The more functional loss was observed in female patients and in patients with poor postoperative radiological results, but statistically insignificant (P>0.05). The more functional loss was observed in patients with underlying medical disease preoperatively and it was statistically significant (P<0.05). We recommend the evaluation of functional status in the elderly after hip fractures.
