Adrenal gland is a rare location for an oncocytic neoplasm. In English literature less than 10 cases of adrenocortical oncocytoma have been reported. We have experienced a case of adrenocortical oncocytoma in a 35-year-old man which was detected incidentally during the ultra-sonographic evaluation of the abdomen for a routine physical examination. This case did not demonstrate any clinical evidence of adrenocortical abnomalities, such as virilization or hypertension. Grossly, the tumor was light to dark tan on cut surface. Light-microscopic examination revealed tumor cells with abundant lipid- sparse eosinophilic cytoplasm and occasional pleomorphic nuclei. Mitotic figures were less than 5/50 HPFs. Tumor cells were positive for vimentin but negative for pancytokeratin, CAM 5.2, chromogranin and synaptophysin. Ultrastructural examination demonstrated abundant mitochondria containing occasional intramitochondrial dense bodies or inclusions.

BACKGROUND: Isolated lung perfusion (ILP) was developed as a new treatment approach to non-resectable primary or metastatic lung cancer, because of its ability to reduce systemic toxicity while delivering high-dose chemotherapeutic agents to the target organs. This research was planned to evaluate the direct toxic effect of high-dose cisplatin to the lung tissue during isolated lung perfusion. MATERIAL AND METHOD: Fifteen mongrel dogs were divided in the perfusate for 40 minutes. The second group was composed of 5 mongrel dogs which underwent ILP with cisplatin 2.5 mg/Kg added to the perfusate for 30 minutes and 10 minutes with washing solution without cisplatin. The third group underwent the same procedure as the second group except cisplatin 5.0 mg/Kg in the perfusate. Activities of serum angiotensin converting enzyme (ACE), tumor necrosis factor-alpha (TNF-alpha), and concentration of serum lactate dehydrogenase (LDH) and blood urea nitrogen/creatinine (BUN/Cr) were analyzed in each groups at the time of pre-perfusion, 1 hour, 1 day, 1 week, and 2 weeks after ILP. RESULT: Serum ACE activities before and 1 hour, 1 day, 1 week, and 2 weeks after ILP in control group were 45.1+/-6.3, 44.6+/-9.3, 46.7+/-9.5, 50.8+/-9.1, 46.1+/-4.3 U/L. Those in cisplatin 2.5 and 5.0 mg/Kg groups were 49.4+/-12.6, 39.0+/-8.6, 42.3+/-15.9, 50.0+/-2.6, 53.8+/-8.3 and 55.5+/-12.3, 47.0+/-6.3, 45.1+/-6.9, 74.8+/-19.5, 60.2+/-12.0 U/L, respectively. Serum TNF-alpha activities in each group before and after ILP were 5.0+/-1.5 / 7.7+/-2.2 / 6.6+/-2.5 / 4.3+/-1.3 / 5.2+/-1.1 (control), 8.7+/-1.6 / 9.9+/-2.2 / 7.9+/-1.5 / 6.3+/-2.2 / 7.4+/-2.4 (cisplatin 2.5 mg/Kg), and 6.9+/-0.7 / 8.9+/-3.4 / 7.9+/-4.0 / 3.3+/-0.9 / 5.8+/-1.3 pg/ml (cisplatin 5.0 mg/Kg). Mean LDH levels of each group were 225.7 / 271.3 / 328.9 / 350.8 / 255.7(control), 235.7 / 265.7 / 336.0 / 379.5 / 299.2 (cisplatin 2.5 mg/Kg), and 259.6 / 285.2 / 340.6 / 433.4 / 292.4 IU/L (cisplatin 5.0 mg/Kg). So there was no significant difference in serum ACE, TNF-alpha, and LDH activity changes after ILP between the 3 groups. And, there was no significant changes in BUN/Cr in each groups, which was independent of ILP and perfused concentration of cisplatin. In addition, all dogs survived the ILP and there was no significant evidence of pulmonary vascular injury after 2 weeks of ILP with cisplatin. CONCLUSION: There was no harmful effect of cisplatin to the lund tissue of the mongrel dog up to 5.0 mg/Kg in perfusate. Therefore, it is perceived to be safe and effective to deliver high-dose cisplatin to the lung without pulmonary toxicity and renal damage with ILP.

Purpose: The purpose of this study was to explore patients’ awareness and treatment experiences with Chronic Obstructive Pulmonary Disease (COPD) through in-depth interviews. The objective was to develop data to support patients in the successful management of their illness. Methods: Purposeful sampling was used to collect information- rich cases and participants were recruited at a university hospital in Daegu, South Korea. Data collection was done through face to face in-depth individual interviews with 10 patients with COPD from November 2016 to December 2018. Interview began with open-ended questions and each interview lasted on average one hour. All interviews were audio-taped and transcribed verbatim and transcripts were analyzed using qualitative thematic analysis. The findings were verified by the participants. Results: Four themes emerged from data analysis: ‘Feeling like the disease is not my disease,’ ‘Terminology spills like a flood,’ ‘Negligent daily disease-management with relief,’ and ‘Relying on health professionals and family members hoping for healing’. Conclusion Participants do not have a clear understanding of their illness nor feel that they are principal agents of their health and illness for treatment and disease management; instead, they depend mainly on their family members and doctors. The findings elucidated the need for increasing patients’ awareness of the illness. Nurses should develop educational support programs to help COPD patients improve their awareness of their illness and successfully manage their treatment.

PURPOSE:Ghrelin is an endogenous ligand of the growth hormone secretagogue receptor, and stomach is the major site of ghrelin secretion. The purpose of this study is to compare the serum ghrelin concentrations between patients with type 2 diabetes mellitus (DM) and normal adults. We studied also whether serum ghrelin levels in the patients with type 2 DM are correlated with body mass index (BMI), serum insulin, lipid profiles, and creatinine levels. METHODS:Forty patients with type 2 DM and forty normal adults were included in this study. We measured heights and weights of the subjects and calculated their BMIs. Blood samples were obtained to measure the ghrelin concentration and their sera were stored at -20degreeC until used. In all subjects, serum ghrelin levels were measured using the commercially available Ghrelin(human) EIA kit. RESULTS:No differences of mean values were detected between the control group and the type 2 diabetic group for age, body weight, BMI, and the levels of serum total cholesterol, triglyceride, HDL cholesterol, and creatinine. But ghrelin level of the type 2 diabetic group (71.1+/-30.5 ng/L) was significantly lower than the control group (139.7+/-36.9 ng/L). In the control group, the ghrelin level showed positive correlation with HDL cholesterol (Pearson's correlation coefficient=0.37, P<0.05). In the diabetic group, the ghrelin level showed weakly positive correlation with insulin concentration. However, there was no significant relationship between serum ghrelin and various parameters in the diabetic patients group. CONCLUSION: In this study, ghrelin concentration in type 2 diabetic patients was lower than that in the control group. In the control group, serum ghrelin concentrations were positively correlated with HDL cholesterol. In the type 2 diabetic group, there was no significant correlation between insulin and ghrelin concentrations.

PURPOSE: This research is to understand the effects of senior simulation on employees of elderly care facilities and utilize it in their job training. METHODS: This research is a nonequivalence control group pre-to-post quasiexperiment research. 18 employees who have experienced senior simulation are set as test group and 18 other employees who have not experienced senior simulation are set as control group. RESULTS: The hypothesis that 'the test group which has experienced senior simulation will show a positive change in their attitude on elderly care, compared to the control group' and 'the test group which has experienced senior simulation will show a positive change in understanding of elders, compared to the control group' was supported. The hypothesis that 'the test group which has experienced senior simulation will show a positive change in job satisfaction and performance of duties, compared to the control group' was dismissed. CONCLUSION: The senior simulation seems to contribute to elderly care facilities employees' change in their viewpoints of elders and broaden their understanding of them. The senior simulation was meaningful to provide basic help with implementing job training programs.

Nitric oxide (NO) has been emerged as an important intracellular and intercellular regulatory molecule having functions as diverse vasodilatation, neural communication, and host defense. In the immune system, NO produced by activated macrophage or neutrophil is known to kill tumor cells as a defense molecule. In addition, recent reports demonstrated that NO could interact with superoxide to generate peroxynitrite (ONOO-), an anion and a potent oxidant, in macrophages or other cellular systems. The production of peroxynitrite has been recognized to be associated with the activation and expression of inducible NO synthase (iNOS). In this study, to evaluate the role of NO and peroxynitrite in murine bladder tumor cells, the author investigate the effect of NO and peroxynitrite on the viability, cytotoxicity, and DNA fragmentation of MBT-2 cells. The results are as followings: 1. Activated macrophages treated with INF-r, LPS, or INF-r+ LPS showed increment of nitrite (NO2) production and cytotoxicity against MBT-2 cells in a dose dependent manner. However, treatment with NGMMA, a NOS inhibitor, decreased NO2- production and cytotoxicity. 2. Treatment with SNP, a nitric oxide donor, increased NO2 production and DNA fragmentation (%), but decreased viability (%) of MBT-2 cells in a concentration dependent manner. 3. Treatment with peroxynitrite increased cytotoxicity and DNA fragmentation, but decreased viability of MBT-2 cells in a concentration dependent manner. 4. NO- and peroxynitrite-mediated increment of cytotoxicity in MBT-2 cells was corresponded to the programmed cell death, apoptosis. Taken together, these data indicate that NO and peroxynitrite elaborated from macrophages or other cellular systems may increase the cytotoxicity of MBT-2 cells via the mechanism of apoptosis.

The develop a simple screening test for identifying Korean elderly at risk of undernutrition, the data of the health-related habits, dietary behaviors and nutrient intakes of the elderly in Chongju were analyzed. Two risk indicators, mean adequacy ratio (MAR) and the respondents perceived health, were used to detect the undernutrition risk of the elderly. In order to select a list of questions for the test, factors a affecting nutritional status and items investigated in previous nutrition surveys of the elderly were considered, and 21 questions were primarily selected. A multiple regression and stepwise regression analysis were used to take out the weak predictors of poor nutrient intake, and to give item weights to the strong predictors, and a list of 17 questions was finally adopted. To determine the cut-point of the test score, sensitivity, and positive predictive values were calculated. The Simple Screening Test developed in this study is a brief, easily scored tool to predict poor nutrient intake and the perceived health status of the elderly. The test may provide a basis of further comprehensive nutritional assessment or intervention planning, if necessary, for those who are diagnosed ad "high risk". The test, however, needs to be independently validated by other groups of individuals.

PURPOSE: This study was done to identify family burden, resilience, spiritual well-being and quality of life of primary caregivers of people with mental illness. METHODS: Participants were 160 primary caregivers of people with mental illness being treated at one of three mental health clinics in Busan. Data were analyzed using descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficients and stepwise multiple regression. RESULTS: Quality of life was positively correlated with resilience (r=.55, p=.006), spiritual well-being (r=.41, p<.001), and negatively correlated with family burden (r=-.28, p<.001). Factors influencing quality of life were resilience (β=.36), family monthly income (β=.24), support from others (β=.20) and education (β=.18). The explanatory power of these factors for quality of life of primary caregivers of people with mental illness was 45%. CONCLUSION: Findings indicate that resilience is the most important factor affecting quality of life of primary caregivers of people with mental illness. Therefore, the development of nursing interventions to improve resilience and enhance the quality of life of primary caregivers is necessary.
