  • Background: Clinoptilolite is a natural zeolite with high adsorption capacity for polar mycotoxins such as aflatoxins. The efficacy of clinoptilolite in ameliorating the toxic effects of aflatoxicosis has been proven in monogastric animals, but there is no such evidence for ruminants. The aim of this study was to evaluate, under field conditions, whether the dietary administration of clinoptilolite in dairy cows could reduce the concentration of aflatoxin M1 ($AFM_1$) in bulk-tank milk, in farms with higher than or close to $0.05{\mu}g/kg$ of milk (European maximum allowed residual level). An objective of the present study was also to investigate the effect of particle size of clinoptilolite on aflatoxin binding. Methods: Fifteen commercial Greek dairy herds with AFM1 concentrations in bulk tank milk ${\geq}0.05{\mu}g/kg$ were selected. Bulk tank milk AFM1 was determined prior to the onset and on day 7 of the experiment. Clinoptilolite was added in the total mixed rations of all farms at the rate of 200 g per animal per day, throughout this period. Two different particle sizes of clinoptilolite were used; less than 0.15 mm in 9 farms (LC group) and less than 0.8 mm in 6 farms (HC group). Results: Clinoptilolite administration significantly reduced $AFM_1$ concentrations in milk in all farms tested at an average rate of 56.2 % (SD: 15.11). The mean milk $AFM_1$ concentration recorded on Day 7 was significantly (P < 0.001) lower compared to that of Day 0 ($0.036{\pm}0.0061$ vs. $0.078{\pm}0.0074{\mu}g/kg$). In LC group farms the reduction of milk $AFM_1$ concentration was significantly higher than HC group farms ($0.046{\pm}0.0074$ vs. $0.036{\pm}0.0061{\mu}g/kg$, P = 0.002). As indicated by the Pearson correlation, there was a significant and strong linear correlation among the milk $AFM_1$ concentrations on Days 0 and 7 (R = 0.95, P < 0.001). Conclusions: Dietary administration of clinoptilolite, especially of smallest particle size, at the rate of 200 g per cow per day can effectively reduce milk $AFM_1$ concentration in dairy cattle and can be used as a preventive measure for the amelioration of the risks associated with the presence of aflatoxins in the milk of dairy cows.

  • Purpose: The purposes of this study were to identify variables related to self-care behavior and to find factors related to the control of hypertension. A cross-sectional study was carried out to provide basic data for effective and continuous hypertension control in the low-income elderly. Methods: This study was performed with a total of 189 subjects who were hypertensive and were receiving pharmacological treatment of hypertension from a community health center in D Metropolitan City. Data were collected through a face to face survey, and systolic and diastolic blood pressure (the mean value of the two measures) were measured during May 2004. Obtained data were analyzed by $x^2$ test, t-test, multiple logistic regression and Pearson's correlation coefficient (using SPSS Version 10.1). Results: 1. According to demographical characteristics, the score of self-care behavior was significantly higher in elders living along ($47.63{\pm}7.276$) than in those living with the family ($45.19{\pm}5.501$) (p<.05), and in those with religion ($47.11{\pm}6.722$) than in those without religion ($45.01{\pm}6.110$) (p<.05) 2. As to blood pressure control, the percentage of blood pressure control within the normal range (systolic 140mmHg, diastolic below 90mmHg) was 37.03%. According to demographical characteristics, the percentage of blood pressure control was significantly lower in those without religion (p<.05). In practicing hypertension self-care behavior, those who do not control salk intake showed a significantly lower percentage of hypertension control (p<.05). The score of hypertension self-care was $48.28{\pm}4.443$ in the controlled group, and $45.42{\pm}7.399$ in the uncontrolled group, showing a significant difference (p<.01). 3. Hypertension self-care behavior was in a positive correlation with blood pressure control (r=.210, p<.05). Conclusion: Attention should be paid to self-care behavior to increase the control of hypertension in the low-income elderly. These results can be used guidances for improving self-care behavior and the control of hypertension in the low-income elderly.

The design of this study was a descriptive correlational study. The subjects of the study were 160 cerebral palsied adolescents attending at special schools located in Seoul and Kyonggi and rehabilitation centers located in Seoul, Kyonggi and Kyongnam province. The data was collected from May 20 to July 20, 2000. The instrument used for this study were the self-concept scale(50items 4point scale) and self-care activities scale(29items 4point scale). Self-Concept Scale had developed by Fitt(1965), which was standardized by Chung(1968) and modified by Kim(1984). Self-Care Activities Scale developed by the researcher through out the consulting of expert and pilot study on the basis of ADL check list developed by Kang(1984) and LDSQ-3(Lambeth Disability Screening Questionnair-3) developed by Na et al. (1995). The data was analyzed by the SPSS/PC+program using frequency, percentage, mean, standard deviation, t-test, ANOVA & Scheffe test and Pearson's correlation coefficient. The results of this study were as follows; 1. The mean score of self-concept was $138.55{\pm}17.20$(range: 50-100), which the item mean score was $2.77{\pm}0.34$(range: 1-4). The score of subarea of the self-concept was the highest score in family self ($3.01{\pm}0.54$) and the lowest score in physical self ($2.52{\pm}0.42$). 2. The mean score of self-care activities was $95.25{\pm}21.69$ (range: 29-116), which the item mean score was $3.28{\pm}0.75$ (range: 1-4). The score of subarea of the self-care activities was the highest score in feeding($3.75{\pm}0.59$) and the lowest score in walking($2.64{\pm}1.21$). 3. There were statistically significant difference in the score of self-concept according to the age (F=3.24, P=.04), the grads (F=4.36, P=.01), and types of cerebral palsy (F=2.42, P=.03). 4. There were statistically significant difference in the score of self-care activities according to the age (F=8.29, P=.00), the grads (F=16.05, P=.00), types of living place (F=6.46, P=.00), types of cerebral palsy (F=48.92, P=.00), whether or not receiving a rehabilitation therapy (t=-3.64, P=.00), whether or not receiving a vocational training (t=2.14, P=.03), and whether or not using a device (t=-7.42, P=.00). 5.

  • A Cerebrovascular accident(CVA), or Stroke is a medical emergency that occurred when the blood supply to the brain is interrupted or blocked. The stroke causes physical function disorder due to hemiparalysis and emotional disorder. Also the stroke patients experience helplessness, powerlessness, sense of alienation and loss of hope. These feelings make the rehabilitation difficult because they lose the will of life. The purpose of this study is to identify the correlation between perceived social support and hope of stroke survivors. The subjects for this study were 100 out-patients with stroke in one general hospital and oriental medicine hospital located in Mokpo. The data were analysed by frequency, t-test, ANOVA. Duncan test, Pearson's correlation, using the SPSS WIN 9.0 program. Data were collected from July 11 to September 9, 2000, using a structured questionnaire. The instruments used for this study : The social support scale developed by Park, Ji-won(1985) and the hope scale developed by Miller(1988). The results were as follows. 1. It was found that the higher the degree of perceived social support, the higher the degree of hope(r=.726, p=.000). Therefore hypothesis was supported. 2. The mean score of perceived social support was 77.8(SD=21.0) with a score range from 27.0 to 104.0. 3. The mean score of perceived hope was 117.0(SD=25.7) with a score range from 57.0 to 160.0. 4. The level of social support depending on general characteristics were significantly different in variables such as marital status(t=3.131, p=.010). degree of income satisfaction(F=16.027, p=.000). 5. The level of hope depending on general characteristics were significantly different in variables such as marital status(t=2.681, p=.040). current job(t=-2.055, p=.043) degree of income, satisfaction(F=11.363, p=.000). For these subjects, there was a significant relationship between social support and hope. The stroke survivors need social support to inspire their hope. Nurses should plan interventions to enhance social support for patients with stroke. The above results may be used as the basic data to seek more efficient way of elevating nursing practice and rehabilitation for the patients with stroke.
