This study was conducted to identify the attributes constituting Korean social support and to validate the results of the previous study 'Search for the meaning of social support in Korean Society.' The informants were 41 Korean middle-aged women in three cities : Seoul, Dagjun and Daeku. The data were collected through indepth interviews using the interview guide from Jun. 1994 to Jun. 1995. The interview guide was developed in the simulated situations of 'Stroke attack' which expected to be in need of social support. The women were asked to answer what they felt and the appropriated terms representing the situations. Data analysis were conducted by content analysis. consequently, the Koran social support pyramid was modified as follows ; Support is the apex of the pyramid. The four sides of the pyramid are made up of 'Jung'(Bound by ties of affection, regard or shared common experience, Connectedness), Do-oom(both emotional and material help), Mi-dum(Faith or belief in) and Sa-Rang(Love). The base of the pyramid is 'yun'(the basic network of relationships in Korean culture) that connote the meaning of Eunhae(Benevolence), Euimu(duty, responsibility) and Dori(obligation).

Germline mutations in the BRCA1 and BRCA2 genes are strong genetic factors for predispositions to breast, ovarian, and other related cancers. This report describes a family with a history of breast and ovarian cancers that harbored a novel BRCA1 germline mutation. A single nucleotide deletion in intron 20, namely c.5332+4delA, was detected in a 43-year-old patient with breast cancer. This mutation led to the skipping of exon 20, which in turn resulted in the production of a truncated BRCA1 protein that was 1773 amino acids in length. The mother of the proband had died due to ovarian cancer and had harbored the same germline mutation. Ectopically expressed mutant BRCA1 protein interacted with the BARD1 protein, but showed a reduced transcriptional function, as demonstrated by the expression of cyclin B1. This novel germline mutation in the BRCA1 gene caused familial breast and ovarian cancers.

PURPOSE: This study was performed to observe the relationship of plasma L-arginine level and the severity of disease and pulmonary artery pressure in respiratory distress syndrome of premature infants. METHODS: Peripheral blood samples were obtained at 1st, 3rd and 7th day from 21 premature in fants with respiratory distress syndrome to analyze the L-arginine concentration. Oxygenation index (OI), an indicator of the severity of the disease, was calculated at the same time of the blood sampling. And pulmonary artery pressure was measured by Doppler echocardiography at each period. Plasma L-arginine level, OI and right ventricular systolic time interval(RVSTI) were analyzed. RESULTS: Plasma L-arginine concentration of the 1st day was lower than 3rd and 7th day. OI and RVSTI were significantly correlated with each other(r=0.772, P<0.01). Plasma L- arginine level was correlated with oxygenation index(r=-0.346, P<0.01) and RVSTI(r=-0.416, P<0.01). CONCLUSIONS: Plasma L-arginine level was lowest in the 1st day during the study period. Plasma L- arginine concentration correlated significantly with the severity of respiratory distress syndrome and pulmonary artery pressure in premature infants.

PURPOSE: A part of seizure disorders, hemosiderin deposits are noted in epileptogenic lesions cytopathologically and iron status may affect the seizure threshold. To investigate this possibility, measures of iron sufficiency were evaluated. METHODS: Children between 6 months and 5 years of age with febrile illnesss with (n=45) or without simple febrile seizures(n=50) were eligible for study. Children with the central nervous system(meningitis or encephalitis) infection, developmental delay, neurologic deficit, or past history of febrile seizures were excluded. RESULTS: The hemoglobin level was 11.99+/-0.96 gm/dL in the febrile seizure and 11.44+/-1.6 gm/dL in the control group. The mean corpuscular volume was 77.9+/-6.2 fL in the febrile seizure group and 74.6+/-10.5 fL in the control group. The mean corpuscular hemoglobin was 26.8+/-2.1 pg in the febrile seizure group and 25.4+/-3.6 pg in the control group. The platelet count was 348.6+/-141.4(x10(9)/L) in the febrile seizure group and 382.3+/-107.3(x10(9)/L) in the control group. The ferritin was 27.5+/-20.2 mg/L in the febrile seizure group and 22.5+/-15.6 mg/L in the control group. CONCLUSION: A relationship between iron deficiency and a reduced risk of febrile seizures is consistent with the study hypothesis that iron deficiency may thereby raise the febrile seizure threshold. Therefore, the effects of antioxidants on the frequency of febrile seizures could be evaluated to test this hypothesis more directly. Studies using iron chelators would be necessary to delineate these possible effects.

PURPOSE: Research related to social support in Korea has been hampered by paucity of measurement tools reflecting Korean culture. The aim of the study was to develop Korean social support questionnaire (KSSQ) based on the Korean social support pyramid and to test psychometric properties of the KSSQ. METHODS: The questionnaire was administered to 701 subjects and 658 college students. Psychometric analyses included factor analyses, expert validity, criterion-related validity, internal consistency, and test-retest reliability. RESULTS: A principal components analysis support for construct validity, eliciting a three factor solution accounting for 65.46% of variance in scores. Concurrent and discriminant validity supported criterion-related validity. Internal consistency of reliability was support with Cronbach's alpha of .97-.98 for the entire scale. Test-retest reliability was .76. CONCLUSION: This initial testing of KSSQ to measure Korean social support demonstrates evidence of reliability and validity. Assessment of known-group validity and norm establishment of KSSQ are suggested to provide further sound psychometric properties and practical measurement tools.

Allergic reactions to local anesthetics are very rare and represent <1% of all adverse local anesthetics reactions. A 54-year-old man was admitted to the hospital in the winter because of shortness of breath. The patient reportedly had an inhalation lung injury due to butane gas fuel. On the fifth day, he developed an asthmatic attack and anaphylactic shock immediately after lidocaine aerosol administration to prepare for bronchoscopy to confirm an acute inhalational lung injury diagnosis. Cardiopulmonary resuscitation was performed immediately after respiratory arrest, and the patient was admitted to the intensive care unit intubated and on a ventilator. He was extubated safely on the third post-cardiopulmonary resuscitation day. These observations suggest that aerosol lidocaine anesthesia may cause airway narrowing and anaphylactic shock. Practitioners should be aware of this potential complication. We report on this case with a brief review of the literature.

PURPOSE: Patients with chronic kidney disease are predisposed to having a stroke. However, there are few data regarding the risk factors of stroke for the mortality and outcome in patients with chronic renal failure on dialysis. This retrospective study was conducted to evaluate the risk factors of stroke and its outcome in patients on dialysis at our hospital. METHODS: We retrospectively analyzed the data of dialysis patients who developed strokes from March 2001 to March 2009. The stroke was diagnosed on the history, physical examination and computed axial tomography or magnetic resonance imaging of the brain. The types of stroke were divided into ischemic or hemorrhagic stroke. RESULTS: The 120 patients were included in this study. Cerebral ischemia was 80 cases (66.7%) and cerebral hemorrhage was 39 cases (32.5%). One case had cerebral ischemia and hemorrhage simultaneously. Stroke occurred most frequently within 1 year after starting dialysis. Patients with cerebral infarction were older than patients with cerebral hemorrhage. Diabetes mellitus (DM) was more frequent in patient with cerebral infarction. Univariate and multivariate Cox analysis showed old age, hypertension and poor mental status are risk factors of mortality. Diuretics use reduced the mortality. CONCLUSION: The incidence of ischemic stroke is twice the higher than that of hemorrhagic stroke in the dialysis population. The risk factors of mortality were old age, hypertension, poor mental status and no diuretic use.

PURPOSE: Leptin is a potent adipokine that plays a significant role in tumor development and the progression of breast cancer. The aim of this study was to evaluate whether leptin affects the response to tamoxifen treatment in estrogen receptor (ER)-positive breast cancer cells. METHODS: Leptin, leptin receptor (Ob-R), and activation of signaling pathways were studied by Western immunoblotting. The effects of leptin on tamoxifen-dependent growth inhibition were studied in MCF-7 and T-47D cells. RESULTS: Leptin was expressed in MCF-7 and T-47D and had a proliferative effect on MCF-7 cells. Leptin significantly inhibited the antiestrogenic effect of tamoxifen in both cells only under beta-estradiol (E2) (20 nM) conditions. In MCF-7, the inhibitory effect against tamoxifen was a result from the activation of the ERK1/2 and STAT3 signal transduction pathway. CONCLUSION: Leptin interferes with the effects of tamoxifen under E2 stimulated conditions in ER-positive breast cancer cells. These results imply that inhibition of leptin is expected to enhance the response to tamoxifen in ER-positive breast cancer cells, and, therefore, could be a promising way to overcome endocrine resistance.

PURPOSE: The purpose of this study was: 1) To investigate health status(health behavior, health problem and cognition), depression and social support of elderly beneficiaries of the National Basic Livelihood Security System. 2) To identify the relationships among health status, depression and social support. METHODS: This descriptive study used a cross-sectional design. The study sample was a total of 883 elderly recipients supported from the National Basic Livelihood Security System. Quotas for sampling were designed and conducted nationwide throughout Korea. RESULTS: The mean age was 76.2 and the 79.6% of the sample were female. The scores for the health behavior, health problem, ADL, and cognition were 23.9, 4.4, 39.6 and 24.9, respectively. Additionally, the depression score was 19.8 and the social support score was 63.2. Gender, age, education, religion, marital status and monthly income were found as important variables in increasing health status and in decreasing depression among the elderly. Furthermore, depression showed a positive correlation with health problems, but showed negative correlations with health behavior, ADL, and cognition. The upper 25% of social support recipients suffered less depression than the lower 25% of the recipients. Subjects with more social supports had higher ADL scores and less health problem. CONCLUSION: These findings provide significant practical implications for nursing intervention, including social support for the elderly receiving assistance from the National Basic Livelihood Security System.
