BACKGROUND: Naringin, one of the flavonoids in citrus fruit peels, is known to have antioxidant and hepatotonic effects in animal studies. We evaluated the effect of naringin on 1) blood lipid profiles, 2) regression of fatty streak of aorta, and 3) liver toxicity in diet-induced hypercholesterolemic rabbits. METHODS: New Zealand White Rabbits (2.0 - 2.5 Kg) were divided to three groups; group without treatment, group treated with 100 mg/kg/d or 500 mg/kg/d naringin, and group treated with 1 mg/kg/d or 20 mg/kg/d lovastatin. They were fed on 0.25% or 1.0% cholesterol-containing diet for 8 weeks and then sacrificed. Blood samples were collected for measurement of total cholesterol, HDL-cholesterol, triglyceride, serum GOT and GPT. Aortas and livers were harvested for evaluation of fatty streak and pathologic examination. RESULTS: 1)Feeding of 1% cholesterol diet for eight weeks significantly increased the cholesterol level upto 20 folds. Neither lovastatin nor naringin did lower these marked hypercholesterolemia. But both naringin (500 mg/kg/d) and lovastatin (1 mg/kg/d) significantly reduced the area of fatty streak by 75% and 58%, respectively. Naringin was more effective in inhibition of fat infiltration into liver than lovastatin which showed hepatotoxicity as increase of serum GPT level (p=0.01). 2)Feeding of 0.25% cholesterol diet for eight weeks significantly increased the cholesterol level upto 17 folds. Total cholesterol and triglyceride levels tended to decrease by treatment with naringin (500 mg/kg/d) and lovastatin (20 mg/kg/d), but this decreases were not statistically significant. However, areas of fatty streak significantly decreased by treatment with naringin and lovastatin by 64 and 82%, respectively (p<0.05). Microscopic analysis revealed that foam cell infiltration into intima was significantly reduced by naringin and lovastatin. In contrast to lovastatin, naringin significantly reduced the level of serum GPT (p<0.05). CONCLUSION: Like lovastatin, naringin has strong antiatherogenic action which may not be associated with its very mild lipid lowering action. In contrast to lovastatin, naringin does have hepatoprotective effect.

PURPOSE: This study was conducted to find out the effects of hospice care by evaluating the spiritual well-being and quality of life in the hospice and nonhospice patients. METHOD: The research design was composed of descriptive study. The data were collected using the questionnaire with interview from 30 hospice patients at three hospice institutes and 30 nonhospice patients at two general hospitals. The tools used for this study were 14-item questionnaire regarding general characteristics, a revised Spiritual Well-being Survey(Paloutzion and Ellision, 1982) and 22-item of revised Mcgill Quality of Life questionnaire. RESULT: The spiritual well-being of the hospice patients was higher than that of nonhospice patients(F=5.52, p=0.023). The global quality of life of the hospice patients was higher than that of nonhospice patients(F=8.84, p=0.004). There was a significant positive correlation between spiritual well-being and quality of life of the hospice patients and non hospice patients. CONCLUSION: The hospice care effects on spiritual well-being and quality of life of the terminal cancer patients.

As a nursing practice involves nurses'actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives. Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal); excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, accountability and commitment(4 theories of nursing ethics); human respect, partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences, positive perspectives(4 theories of nurse), role of intervention, rewarding, peer relationship(3 theories of situations). The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore, it is recommended to review the theories-in-use in order to find any discrepancies between the espoused theories and the reality of nursing actions.

PURPOSE: To report two cases of conjunctival mucosa-associated lymphoid tissue (MALT) lymphomas treated with cryotherapy. CASE SUMMARY: Two patients with MALT lymphoma of the conjunctiva were treated by carbon dioxide cryotherapy under topical anesthesia using 0.5% proparacaine hydrochloride (Alcaine(R), Alcon). Cryotherapy was repeated in recurrent lesions up to three times. One patient was free of the tumor for 18 months of follow-up after the third cryotherapy was performed. The second patient had complete disease arrest for 9 months after the third cryotherapy. Neither patient experienced complications during the follow-up period. CONCLUSIONS: Cryotherapy is a comparatively easy treatment tool with fewer complications for patients, making it preferable from a patient's perspective as well. Cryotherapy may be a useful treatment modality in patients with MALT lymphomas localized to the conjunctiva.

PURPOSE: The purpose of this study was to evaluate the HRCT findings of bronchial asthma during maintenance bronchodilator therapy and to determine whether there were irreversible bronchial changes occurred in pediatric patients with this condition. MATERIALS AND METHODS: HRCT findings of the lung in 21 asthmatic children [14 boys and 7 girls aged between 3.5 and 13.8 (mean : 7.7) years] who were receiving maintenance bronchodilator therapy were retrospectively studied. At the time of CT examination, 16 were receiving nonsteroid bronchodilator therapy only, and five were receiving both bronchodilator and steroid therapy. Thirteen patients were defined as allergic and eight were nonallergic. The clinical severity of chronic asthma was graded as severe in seven cases, and moderate in 14. The duration of the disease ranged from 4 months to 6 years (mean 3.2 years). HRCT was performed in 19 cases for evalvation of the atelectasis, hyperinflation, and prominent bronchovascular bundles seen on plain radiographs, and in two cases for evaluation following acute exacerbation. A CT W-2000 scanner (Hitachi Medical Co. Tokyo, Japan) was used during the end inspiratory phase, and in addition, ten patients were scanned during the expiratory phase. Scans were reviewed for evidence of bronchial thickening, bronchiectasis, emphysema, abnormal density, mucus plugs, and other morphological abnormalities. The presence of bronchial wall thickening or air trapping was evaluated according to the duration, severity and type of asthma. RESULTS: Among the 21 patients, 7(33.3%) had normal HRCT findings, while in 14 (66.7%), bronchial wall thickening was demonstrated. Eleven of the 14 patients with bronchial wall thickening (78.6%) also had air trapping. No patient was suffering from bronchiectasis or emphysema. There were no statistically significant correlations between the presence of bronchial wall thickening or air trapping and the duration of the disease, its severity, or type of asthma. There was, however, a statistically significant correlation between bronchial wall thickening and air trapping (p < . 0 5 ). CONCLUSION: In asthmatic children who were under maintenance therapy, the most frequent HRCT findings were bronchial wall thickening and air trapping, with significant correlation between the presence of these two phenomena. No destructive lesion such as bronchiectasis or emphysema was found in these asthmatic children, however, and this is probably due to the short duration of the disease, and different disease processes.

Socialization is the process of moving from one social role to another by gaining knowledge, skills and behaviors to participate in a group. Nurses who graduate from nursing school, enter the work force, and develop a career undergo socialization as they become insiders in the hospital. This study was designed to identify experiences of the nurses' socialization process in the hospital setting. The subjects were 6 nurses. Data were collected by recording and transcribing interviews and analyzed in the framework of grounded theory as mapped out by Strauss and Corbin(1990). The core category in the analysis of the experiences of nurses' socialization process was "being beyond". In the process of data analysis, 22 categories were identified. These categories were again grouped into 13. Based upon these results, it is recommended that development of resocialization models to establish nursing identity are necessary.

PURPOSE: To describe the angiographic findings of patients with recurrent hemoptysis after bronchial artery embolization (BAE) according to the point at which relapse occurred. MATERIALS AND METHODS: From 125 patients who underwent BAE due to hemoptysis between 1996 and 2000, we selected 18 of 23 who underwent additional BAE due to recurrent bleeding after initial BAE . Depending on the point at which relapse occurred, they were divided into two groups (I and II, according to whether additional BAE was performed within two weeks of initial BAE or more than two weeks after this). We retrospectively compared the two groups in terms of angiographic findings, number of embolized arteries, and character of feeding arteries at initial and additional BAE. RESULTS: Nine patients in group I (additional BAE: n=10) and nine in group II (additional BAE: n=13) were admitted for recurrent hemoptysis within two weeks of initial BAE and more than two weeks after this, respectively. In group I(n=29) and II(n=31), angiography demonstrated two direct and 27 indirect, and two direct and 29 indirect signs of hemorrhage, respectively. No statistically significant differences were observed (x2=0.005, p=0.945). Among the embolized feeder ressels in group I (n=30) there were 20 bronchial artery and 10 non bronchial systemic collaterals, while for group II(n=35), the corresponding totals were 21 and 14. Again, no statistically significant differences were encountered(x2=0.308; p=0.579). In group I, feeders were newly developed in one case(10%), previously embolized in five(50%), and missed in four(40%), while in group two the corresponding figures were none, twelve(92.3%), and one(7.7%). No significant differences were noted, though the incidence of previously embolized feeders in Group II was very high (x2=5.383, p=0.068). CONCLUSION: Among patients in whom hemoptysis after BAE recurred at different times, the angiographic findings and number of embolized arteries were not significantly different, but differences in the nature of the feeder were noted. Patients in whom hemoptysis recurred more than two weeks after BAE showed more recanalization of previously embolized feeders than those in whom there was recurrence within two weeks.
