Korean student nurses may be exposed to stress caused by their future employment (employment stress). The aim of this study was to investigate the effects of a Laughter Program on psychological stress, by assessing salivary cortisol and the subjective happiness of student nurses in order to relieve employment stress.

This study was conducted to identify the factors related to the blood pressure in school children. The study subjects were 144 boys and 140 girls aged 10 years old, 4th grade student of one elementary school in Taegu City. Blood pressure and 18 variables for 284 school children were measured in May 1992. A weight-for-height index, Rohrer index(weightlheighe) was calculated for each individual as a measure of obesity. Body fat percent, fat weight, and lean body mass were measured by impedance fat meter(Model SIF-891). Serum total cholesterol, higli-density lipoprotein, triglyceride, uric acid, total protein, and electrolyte were measured by automated clinical chemistry analyzer(Hitachi 4020). Low-density lipoprotein and atherogenic index were calculated by the equation. The variables assessed were sex, systolic blood pressure, diastolic blood pressure, Rohrer index, body fat percent, body fat weight, lean body mass, total cholesterol, high-density lipoprotein, low-density lipoprotein, uric acid, total protein, serum electrolyte and blood glucose. The mean systolic and diastolic blood pressures for boys were 104.1mmHg and 66.6mmHg and those for girls were 102.9mmHg and 67.5mmHg. Systolic blood pressure of boys was positively correlated with height, weight, Rohrer index, fat weight, lean body mass, and triglyceride. Systolic blood pressure of girls was positively correlated with height, weight, lean body mass, and uric acid. Diastolic blood pressure of boys was positively correlated with weight, Rohrer index, and lean body mass. Diastolic blood pressure of girls was positively correlated with height, weight, fat weight, and lean body mass and negatively with total serum protein. In multiple regression analysis for the systolic blood pressure, the significant independent variables were Rohrer index and serum sodium in boys, and serum uric acid, fat percent, and Rohrer index in girls. In multiple regression analysis of the diastolic blood pressure, the significant independent variables were Rohrer index in boys and total serum protein in girls. This study indicated that important factors influencing blood pressure in school children were Rohrer index, fat percent, serum sodium, uric acid, and total protein. Rohrer index was most important among these. It is recommended to enforce the nutritional education for diet control of obesity to prevent hypertention in children and to adopt healthy life-styles that promote good health and prevent development of cardiovascular risk factors.

Re-188 is suitable for endovascular liquid-balloon brachytherapy for the prevention of restenosis after angioplasty. Re-188 was concentrated to 3700 MBq/ml and labeled with DTPA. According to dosimetric calculation, it took 420 seconds using Re-188 solution with concentration of 3700 MBq/ml to irradiate 17.6 Gy to the target at 1 mm from the balloon surface. Software was made to estimate the irradiation time. MIRD calculation with dynamic bladder model yielded the whole body dose of Re-188-DTPA as 0.005mGy/MBq in case of balloon rupture and release of the whole amount into the blood.

Malignant melanoma is unique in its propensity to metastasize to the heart with frequencies ranging from 50% to 71%. We report a case of a resection of large intracavitary malignant melanoma causing obstruction of the right ventricular inflow and outflow tract of the heart. A 49-year-old-woman presented clinical symptoms and signs of life-threatening congestive right heart failure. Transthoracic and transesophageal echocardiography revealed a large intracavitary mass occupying the entire right ventricle. Inguinal lymph node biopsy demonstrated metastatic melanoma. The cardiac main mass was palliatively resected and demonstrated to be a metastatic melanoma. The patient improved symptomatically about 60 days after the operation.

Gated myocardial SPECT and attenuation correction gave birth to new insights into the pathophysiology of ischemic myocardial perfusion and function in clinical routine practice. Gated myocardial Tc-99m-compound SPECT improved diagnostic accuracy of coronary artery disease and enabled us to observe motion and thickening of myocardial walls as well as myocardial perfusion at the same time. Quantitative and qualitative assessement of myocardial performance and perfusion let us to understand the myocardial physiology in ischemia and infarction. In every patient who underwent gated perfusion SPECT, we will find ejection fraction, left ventricular volumes and regional wall motion. There are hopes to use gated T1-201 SPECT for the same purpose and to use gated SPECT for evaluation of wall motion and thickening at stress or immediate post-stress. Attenuation correction could improve diagnostic accuracy mainly by increasing normalcy ratio or performance of non-expert physicians. Both gated methods and attenuation correction improved specificity of non-expert physicians in diagnosing patients with moderate pretest likelihood. New imaging techniques will fill the desire of cardiologists examine function and perfusion, and possibly metabolism in their clinical routine practice.

For the purpose of further health control, D-penicillamine was orally administered to 8 persons who were employed in lead industry and suspected lead intoxication routine industrial health examination. The dose of D-penicillamine was 600 mg per day and was administered orally in every other 5 days. For the laboratory analyses 24 hours urine and 10 gm of whole blood were collected every day. The results were as follows ; 1. It was found that mean urinary lead excretion per day was 446.5 g/l and 394.98 g/l, respectively during the first 5-day and the second 5-day administration with D-penicillamine. 2. Mean lead excretion per day was 130.56 +/- 66.42 g/l after first 5-day administration and 159.28 +/- 104.44 g/l after second 5-day administration with D-penicillamine. 3. The level of urinary lead excretion after administration increased 3 to 4 times than that before administration with D-penicillamine. 4. Blood and urinary lead level investigate after 6 months were 44.4 +/- 10.2 g/100g and 72.7 +/- 29.7 g/l for the eight persons.
