The isolated coronary ostial stenosis is a lesion of the aortic wall that encroaches on the orifice of the left main coronary artery, atherosclerosis is belived to be a common cause and premenopausal female patients are most commonly affected. Stenosis of the left coronary ostium is a critical lesion which requires urgent myocardial revascularization including a surgical intervention because this lesion jeopardizes such a large volume of left ventricular myocardium. We report the case of a patient in whom percutaneous transluminal coronary angioplasty (PTCA) was performed successfully for the stenotic lesion of distal anastomotic site after surgical ostioplasty with autologous pericardium.

PURPOSE: Endothelin-1(ET-1) is a potent vasoconstrictor peptide. It has potent contractile and proliferative effects on vascular smooth muscle cells. Congenital heart diseases are often accompanied by pulmonary hypertension, and the severity of pulmonary hypertension is important in the prognosis. The aim of this study was to elucidate changes of ET-1 after pulmonary venous stenosis in a dog model, and investigate the interaction between pulmonary venous pressure and ET-1. METHODS: Plasma ET-1 levels were measured by radioimmuno-assay at the thoracic aorta, left pulmonary artery and left pulmonary vein. Pressures were also monitored at the same sites. Immunohistochemical staining of ET-1 was performed in the lung tissue. RESULTS: Increased serum ET-1 levels were noted at 1 hour after left pulmonary vein stenosis in the left pulmonary vein and aorta, and at 2 days after stenosis in the left pulmonary artery. Left pulmonary venous pressure was significantly increased at 1 hour after pulmonary vein stenosis, and systolic pulmonary artery pressure at 2 days after stenosis. Increased expression of ET-1 was noted by immunohistochemical staining at the lung tissue at 7 days after stenosis of left pulmonary vein. CONCLUSION: Increased serum ET-1 level and expression of ET-1 in immunohistochemical staining at lung tissue were noted after stenosis of pulmonary vein. Serum ET-1 level would be useful in the diagnosis and prediction of pulmonary artery hypertension. (J Korean Pediatr Soc 2000;43:769 778)

In orper to measure the levels of high density lipoprotein cholesterol in psoriasis, 60 psoriatic patients and 30 healthy subjects were included in this study. Lopez-Virells methos was applied for measuring the serum level of high density lipoprotein cholesterol. The results were obtained as follows. The level of serurn HDL cholesterol was 58. 39+17. 40 mg/dl in psoratcs and 50.3+0.31 mg/dl in healthy subjects and 50. 43+ 10. 31 mg/dl in healthy subjects. No significant differences were noted between psoriatics & healthy subjects. 2. The level of serum HDL cholesterol was 56. 40+19. 10 mg/dl in male group of psoriatics and 60. 00+15.47 mg/dl in female group of psoriatics and 48.3+9. 50 mg/dl in healthy male group and 52.60 -10.59 mg/dl in healthy female group. No significant differences of serum HDL cholesteol levels were noted in both sexes.3. The mean value of serum HDL cholesterol by age groups of 10, 20, 30, 40, and 50 years old with psoriasis were 50. 70 mg/dl, 61. 97 mg/dl, 57. 44 mg/dl, 49. 11 mg/dl and 70. 36 mg/dl, respectively and those of healthy groups were 57. 25 mg/ dl, 45. 17 rng/dl, 50. 97 rng/dl, 48. 07 mg/dl and 46. 98 mg/dl, respectively.

Under the extreme change of the environment, animals react physiologically to adapt to the stress and secrete catecholamines. Cold exposure is a kind of the environmental stress. Author tried to determine the amount of catecholamines in rat urine as a parameter of physiological response to cold stress. Urinary catecholamine was measured by using HPLC with fluorescence detector, coation exchange column prepacked with Bio-Rex 70 and ammonium pentaborate as catecholamine eluent. The amount of dopamine in normal state rat urine was 42.0 ng, but under the low temperature of 5 degrees C, the dopamine amount was increased to 221.25 ng/5 ml. Above findings are suggesting that catecholamine secretion, especially dopamine, increase in the stressful condition such as cold exposure.

Purpose: The purpose of this study was to examine the effects of a video education program in women receiving high-intensity focused ultrasound(HIFU) treatment. Methods: This was a quasi-experimental study with a nonequivalent control group non-synchronized design. The participants were 54 patients who had benign uterine tumorsand adenomyosis. The data were collected from June to August 2018. The experimental group was provided a video education program with a question-and-answer session for 10 minutes after viewing the video. A 10-minute video education program on HIFU and post-procedural care was developed based on the literature.The control group received usual care (i.e., verbal instructions on post-procedural care). The questionnaire survey was conducted twice: before the educational program and before being discharged from the hospital. Differences in uncertainty, emotions, and self-efficacyamong patients were analyzed. Data were analyzed using the chi-square test, the t-test, the Shapiro-Wilk test, the paired t-test, and the t-test with SPSS for Windows version 23.0. Results: The participants in the experimental group showed a decrease in uncertainty(t=4.33, p<.001), improvements in anxiety(t=–4.07, p<.001) and depression(t=–3.55,p<.001),and an enhancement ofself-efficacy(t=–4.39,p<.001) compared to the control group. Conclusion This nursing intervention was effective at reducing uncertainty, improving emotions, and enhancing self-efficacy. We hope that it will be applied to improve nursing practice and that it will be valuable when utilized for helping patients to choose a treatment method.
