It has been suggested that the fish oil can reduce atherogenesis in humans and animals, and that peroxidation of lipoproteins may be a major factor causing atherosclerotic lesions. We tested these posibilities in rabbits fed an atherogenic diet by comparing the effect of a eicosapentaenoic acid(EPA: a major component of fish oil)supplement and a butyrated hydroxyanisole(BHA: antioxidant)diet supplement. Tweenty-eight young male New Zealand White rabbits were used in this study. The animals were divided by control, cholesterol fed only, cholesterol + EPA, and cholesterol + BHA groups. The experimental course lasted 12 weeks and animals were sacrificed periodically(2, 5, 8, 12weeks)for quantitative studies of aortic atherosclerosis using light and electron microscopy. Plasma cholesterol levels were determined and lipopreteins were separated periodically. The cholesterol fed only group showed an increased serum cholseterol level and atherosclerotic lesions from 5 weeks of experiments. The EPA supplement resulted in similiar serum cholesterol levels with cholesterol fed only group, but greater lesion than cholesterol fed only group. The BHA supplement resulted in higher serum cholesterol levels except VLDL-cholesterol than EPA supplement group. However, the atherosclerotic lesion was not increased. Our studies support the theory that oxidative modification of lipoproteins is important for the atherogenesis and antioxidant may have a protective effect. However, it failed to show antiatherogenesis effect of fish oil.

BACKGROUND: The rapid increase in population of old people has been emphasized as a serious social problem even in medical world. Geriatric disease has special characters that can be mentioned as a non-contagious chronic degenerative disease. 'Regular Doctor System' can be considered as one of the efficient ways to care for it continuously. The purpose of this study was to promote the introduction of family doctor system gradually and care of geriatric disease through examination of old people's thinking about 'Regular Doctor System'. METHODS: The result of this study was based on the questionnaire survey on 292 old people(aged 65 and more, response rate 73%) at 2 welfare centers in Seoul, located at Yeongdeungpo-gu and Guro-gu, and 1 college for old people, for 2 weeks from May, 2003. The contents of surveywere consisted of many questions for understanding of old people's thinking about 'Regular Doctor System'. The response method was self-reported. RESULTS: Comparing with other age group surveys, this old people's survey has special character that it has higher affirmative answer rate for the question of 'Do you have a regular doctor?'. The old people's favorite natures of regular doctor were considerateness( 26.9%) and kindness(26.2%). And the most desirable service from their regular doctor was comprehensive health examination( 45.2%). The factors reflecting on selecting of doctor were separately questioned into two aspects, as factors related to doctor's behavior and the others. Among the factors related to doctor's behavior, the effect of medical treatment(22.7%) was top ranked and 'being aware of my disease'(17.3%), 'easy explanation'(15.5%) were followed. The other factors were medical specialty(24,1%), easy access(19.3%) and short waiting time(10.5%). The reasons for changing of doctor were 'to receive specialist's medical treatment'( 37.2%), 'no improvement of patient's condition'(13.1%) and 'distrust of diagnosis'(9.0%). CONCLUSION: The old people wanted considerate and kind attitude from their doctors. The factors, related to doctor's behavior that the old people wanted, were 'good effect of medical treatment', 'being aware of my disease well' and 'easy explanation'. The other factors they wanted were medical specialty, easy accessibility and short waiting time.

Interstitial pneumonia is a heterogenous group of inflammatory and fibrosing lesions that manifest themselves as infiltrative lung disease. Of these, nonspecific interstitial pneumonia is characterized as a variable degree of interstitial inflammation with or without fibrosis and is distinguished from usual interstitial pneumonia and desquamative interstitial pneumonia, histologically. The influx of inflammatory cells and the responses of immune effector cells injury to the alveolar wall and these initial injuries results in alveolitis and fibrosis. Consequently, the gas exchange throughout the alveolar wall is impaired and the patients suffer from lung diseases of a restrictive pattern. The chief complaints represented are dyspnea and dry cough. We experienced a case of nonspecific interstitial pneumonia in a 10-year old girl. The patient had been healthy and had not been exposed to organic dusts or other toxic materials. The pathology of lung biopsy tissue showed that the alveoli were thickened by a mixture of chronic inflammatory cells and collagen type fibrosis. High resolution computed tomography(HRCT) found the patchy areas of ground-glass opacity with patchy consolidation and irregular reticular opacity, and diffuse distribution without zonal predominance. The forced vital capicity(FVC) was 31%, forced expiratory volume in one second (FEV1) 29% and FEV1/FVC 90%, so a restrictive pulmonary insufficiency was found.

BACKGROUND: Recently, the mass media serves a major role in the public health education, but have not been proven whether they are being appropriately utilized in the elderly. The aim of this study was to identify the elderly person's concern in the mass media health information and utilization behavior. METHODS: Between March to June 2008, one to one survey with the elderly people over 60 years was performed in two elderly welfare centers, one public health center, and two secondary hospitals outpatients and inpatients in Seoul and Chungju. RESULTS: A total of 999 subjects were included. By multivariate analysis, factors significantly associated with low concern in the mass media health information were low educational level, non-exercise group, and low concern in own health (P = 0.001, 0.009, < 0.001, respectively). The most frequently utilized health information source was the mass media. By comparing the frequency of health information utilization, women, low educational level, low income, non-exercise group, underweight, low level of self-evaluated health status, and low concern in health information were significantly associated with the lowest quintile of utilization (P value: < 0.001, 0.005, 0.05, < 0.001, 0.002, 0.03, 0.005, respectively). However, the presence of chronic diseases, such as hypertension, diabetes, had no association. CONCLUSION: In community-dwelling elderly, important factors associated with concern in and utilization of the mass media health information were concern in health, self-evaluated health status, exercise status and socioeconomic factors such as education or income level, rather than comorbid chronic disease.

BACKGROUND: Constipation is one of the most common digestive complaints. Although, there are increased interest on the socioeconomic effect of constipation and studies associated with quality of life on constipation, there is no study about the influence of constipation onto quality of life (QOL) in Korea. We studied the impact of functional constipation on QOL. METHODS: Between March to June 2008, person to person survey with 844 elderly aged over 60 years was performed at two senior care centers, a public health center, and secondary hospital in Seoul metrocity and Chung-ju city. The diagnosis of functional constipation was based on the Rome III criteria and QOL was measured by the Medical Outcomes Study (MOS) 36-Item Short-Form Health Survey (SF-36). RESULTS: The average age was 73.6 years and the prevalence rate of constipation was 20.3%. The average SF-36 score was 63.5 in total population, 57.9 in constipation group, and 64.9 in normal group. CONCLUSION: These results suggest that the constipation lowers QOL in adults aged over 60 years old. Further study will be necessary to explore if QOL changes according to the severity of constipation and its treatment and to assess QOL using a disease-specific measurement tool that can be used for Korean environment.
