With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

The number of workers with noise induced hearing loss which comprise 56.9% in the total number of workers with work-related diseases in Korea of 1994, are becoming in position of the most serious problem. Periodic health examination system which was introduced for health care of workers on hazardous workplace has played important role in health care and the prevention of work-related diseases. The goal of periodic health examination may be obtained when we not only discover occupational disease, but also control them effectively. To study the post-examination health status of workers with noise induced hearing loss diagnosed from 1991 to 1994 in the periodic health examination, all 154 workers in 102 manufacturing factories in Banwol and Siwha industrial complex were reviewed. 1. Among 154 workers, 87 workers(56.5%) were changed to different department, 67 workers(43.5%) remained in the same department. 2. Among 102 workplaces, only 23 workplaces(22.9%) had changed their working environment while 79 workplaces(77.1%) did not. 3. In this study, post-examination health care of the workers diagnosed as noise induced hearing loss had significant correlated with the presence of health care manager, Industrial Health and Safety Committee in workplace and size of industry. The improvement of working environment is also closely related with the presence of health care manager in workplace. 4. Among 154 respondents, 3 workers(1.9%) had received compensation while 151 workers(98.1%) did not. 5. The reasons for not requesting the compensation were that 117 workers(77.5%) were ignorant of the administrative procedure for compensation, 30 workers(19.9%) were not sure of receiving compensation, 4 workers(2.6%) were busy. Considering the result of this study, we must establish the guide of management or contents of post management for noise induced hearing loss. To prevent the noise induced hearing loss, and protect the workers with noise induced hearing loss, education about post management is much required for employer and employee.

Chromium occurs naturally in the earth's crust as well as in air, surface, and ground water. However, chromium is released to the environment in much larger amounts as a result of human activities. Hexavalent chromium, Cr(Ⅵ), is very soluble in water in natural environment and very toxic, carcinogenic, and mutagenic in animal and man. On the other hand trivalent chromium, Cr(Ⅲ), is less toxic and less soluble and thus is a lesser problem. This study has been carried out in order to reduce toxicity of Cr(Ⅵ) by an Escherichia coli strain. After adding E. Coli., the results were obtained from concentration of total Cr, Cr(Ⅵ). Cr(Ⅲ), pH, turbidity, and VSS in aerobic condition was summarized as follows : After 48hr aerobic condition in experiment of synthetic wastewater, the reduction rate of Cr(Ⅵ) was 20%. Also, the reduction rate of Cr(Ⅵ) was 60% in experiment of raw wastewater.

Background: Adenosine interacts with A1 receptors present on the extracellular surface of cardiac cells, activating K+channels in a fashion. It produces coronary vasodilatation and AV nodal block. The half-time is one to six second and has ultra-short action. In ischemic heart disease, fractional flow reserve(FFR) can be achieved safely with intravenous adenosine infusions at a rate of 150㎍/kg/min which cause maximal coronary hyperemia. Purpose: We investigated the patients who have had ischemic heart disease(n=8). After adenosine intravenous administration(150㎍/kg/min), the effect cause maximal hyperemia of coronary artery. During peak maximal hyperemia, we reported clinical findings, coronary hemodynamics and electrocardiogram findings. Methods: After diagnostic coronary angiography and left ventriculography, catheter was advanced into the ostium of coronary artery. We investigated coronary hemodynamics such as systolic coronary artery pressure, diastolic coronary artery pressure, mean coronary artery pressure and heart rate. To assess the use of adenosine for determination of fractional flow reserve, hemodynamics and electrocardiogram were measured at basal state and during peak maximal hyperemia. Results: Symptoms developed 1.5-2 minute after adenosine intravenous administration and each symptom disappeared 2-2.5 minute after adenosine administration. Two patients represented asymptomatic appearance and six patients complained of flushing, chest pain, palpitation and headache. In eight patients with ischemic heart disease, 1.5 minute after venous administration of 150㎍/kg/min of adenosine, coronary artery pressure decreased and heart rate increased significantly. Conduction abnormalities after administration of 150㎍/kg/min of adenosine were transient 2nd degree AV block 2 cases(25%). Conclusions: Adenosine is a potent ultra short-acting vasodilator. Although coronary artery pressure decreased and heart rate increased and mild cardiovascular symptoms occurred after continuous infusion of 150㎍/kg/min of adenosine, it is useful as an agent for determination of fractional flow reserve.

We are able to generate the stable plasma in open air and nitrogen using a corona plasma treatment system(CPTS) with a high voltage. This was applied to treat the surface of rather non-polar HDPE(High Density Polyethylene) intended for the improvement of adhesion of over-coated layers such as coatings, printing inks. The surface tension of HDPE was significantly improved by the CPTS. The characteristics of surface layer were evaluated by means of contact angle measurement, ATR-FT/IR spectroscopy, and it was found that functional groups were introduced into the surface layer of the HDPE. The use of nitrogen was increased the surface tension of the HDPE from 33.8 mJ/m^2 to 66.56 mJ/m^2, and highly effective method of HDPE surface modification could be realized.

Drug interactions with food, on occasion, led to serious nutritional and functional changes in the body as well as alterations of pharmacological effect. It, therefore, should be necessary to take drug interactions with food into consideration for effective and safe therapeutics. Diabetes mellitus is a heterogeneous group of disorders characterized by abnormal glucose homeostasis, resulting in hyperglycemia, and is associated with increased risk of microvascular, macrovascular, and neuropathic complications. However, the precise mechanism of diabetes mellitus remins unclear. Three basic objectives in the care of diabetic patients are maintaining optimal nutrition, avoiding hypo-or hyperglycemia and preventing complications. Laminaria japonica is a brown macroalgae which can be used as a functional diet due to high content of diatery fiber. the purpose of this study was to investigate the effect of Laminaria japonica diet on the pharmacokinetics of metformin which are frequently used in the treatment of diabetes. Diabetic rats induced by strep-tozotocin were employed in this study. Blood concentrations of oral hypoglycemic agent, metformin, were measured by HPLC and resultant pharmacokinetic parameters were calculated by RSTRIP. The mechanisms of drug interaction with food were evaluated on the basis of pharmacokinetic parameters such as k_(a), t_(1/2), C_(max), t_(max), and AUC, C_(max), and k_(a), and increase in t_(max), compared to those with normal diet. This oral glucose test showed that Laminaria japonica diet could lower blood glucose level probably through either inhibiting the activity of disaccharidases, intestinal digestive enzymes, or delaying the absorption of glucose. More studies should be followed to fully understand pharmacokinetic changes of metformin caused by ong-term Laminaria japonica diet.

Background: Cholestatic hepatitis is failure of bile to reach the duodenum with hepatocellular damage and no demonstrable obstruction of the major bile ducts. The prognosis is usually good with recovery in less than 4 weeks after withdrawal of the offending drug. However, a prolonged course lasting over 3 months is possible and, in rare cases, progression to ductopenia with development of a vanishing bile duct syndrome occurs. A differential diagnosis with other causes of Chronic liver disease is needed. Materials and Methods: From January 1991 through Jaunary 2000, 14 patients diagnosed as cholestatic hepatitis by liver biopsy were inclouded. The possible causative drug, clinical features, laboatory findings, and progression of cholestatic hepatitis were evaluated. The semiquantitative study of liver lesions was performed by two independent observers. Results: Causes of cholestatic hepatitis are 5 cases of oriental medicine, 3 cases of anti-tuberculosis medication, 1 case of ticlopidine and antibiotics and 4 cases of unknown causes. The clinical features of cholestatic hepatitis were jaundice, itching, urine color change, and general weakness. During 6 to 30 months, LFT of 5 patients showed prolonged elevation. Elevated total cholesterol ≥250 mg/dL in 6 patients, pheripheral blood eosinophilia in 5 patients, auto-antibody positive in 6 patients were observed respectively. The biopsies showed intralobular bilirubinostasis with a mixed portal inflammatory infiltration. Conclusion: In cholestatic hepatitis. durations of abnormal LFT are variable regardless of causative drugs. If cholestatic hepatitis progresses toward chronic course, viral hepatitis, primary biliary cirrhosis, and autoimmune hepatitis should be differentially diagnosed and sequential liver biopsies are needed.
