PURPOSE: This study is to examine how dementia day care service affects fatigue, depression and life satisfaction of caregiver. METHODS: The study was conducted using a convenient sampling method from 6 Dementia Day Care Center in Incheon. Thirty nine primary caregivers answered the questionnaires. Pre-test was done before demented elders start using the dementia day care center and post-test was done five months after. Data were analyzed by using descriptive statistics and paired t-test. RESULTS: There was a significant difference in caregivers' fatigue level after using dementia day care service(t=2.188, p=.035). Results of subcategories were as follows; There was a significant difference in caregivers' physical fatigue level(t=2.270, p=.029) and psychological fatigue level(t=2.277, p=.029) after using dementia day care service. However, there was not significant difference in caregivers' neurological fatigue level(t=1.312, p=.197). There was a significant difference in caregivers' depression level(t=3.066, p=.004) and life satisfaction(t=-2.131, p=.040) after using dementia day care service. CONCLUSION: The results indicated that dementia day care service is helpful for family with demented elders. Therefore it is necessary to expand dementia day care center in terms of its size and numbers in order to support increasing number of demented elders and their families.

PURPOSE: We evaluated three blood glucose self-monitoring for measuring whole blood glucose levels in preterm and low-birth-weight infants. METHODS: Between December 1, 2012 and March 31, 2013, 230 blood samples were collected from 50 newborns, who weighed, < or =2,300 g or were < or =36 weeks old, in the the neonatal intensive care unit of Eulji University Hospital. Three blood glucose self-monitoring (A: Precision Pcx, Abbott; B: One-Touch Verio, Johnson & Johnson; C: LifeScan SureStep Flexx, Johnson & Johnson) were used for the blood glucose measurements. The results were compared to those obtained using laboratory equipment (D: Advia chemical analyzer, Siemens Healthcare Diagnostics Inc.). RESULTS: The correlation coefficients between laboratory equipment and the three blood glucose self-monitoring (A, B, and C) were found to be 0.888, 0.884, and 0.900, respectively. For glucose levels< or =60 mg/dL, the correlation coefficients were 0.674, 0.687, and 0.679, respectively. For glucose levels>60 mg/dL, the correlation coefficients were 0.822, 0.819, and 0.839, respectively. All correlation coefficients were statistically significant. And the values from the blood glucose self-monitoring were not significantly different from the value of the laboratory equipment , after correcting for each device's average value (P>0.05). When using laboratory equipment (blood glucose < or =60 mg/dL), each device had a sensitivity of 0.458, 0.604, and 0.688 and a specificity of 0.995, 0.989, and 0.989, respectively. CONCLUSION: Significant difference is not found between three blood glucose self-monitoring and laboratory equipment. But correlation between the measured values from blood glucose self-monitoring and laboratory equipment is lower in preterm or low-birth-weight infants than adults.

We surveyed 343 female bank clerks to find out associations between stress and a variety of factors including general, menstruation and reproductive characteristics of the participants. Unmarried women composed the majority of younger, lower income and lower education groups than married did. They also showed higher. though not significantly higher, scores for psychosocial well being index(PWJ) and the first three items of the stress survey. And married women scored slightly higher only in the fourth item of the stress survey. Among the subgroups of married and unmarried women, many factors contributed to a higher stress score in two or more items of the stress survey; in unmarried women, lower education level, little physical exercise, and large family inhabitants, in contrast married women, higher monthly income and greater working hours were related to higher stress scores. According to the menstruation factors, subgroups with dysmenorrhea or irregular cycle and scanty bleedig volume in unmarried women and subgroups with dysmenorrhea in married women showed higher stress scores in PWI. In married women, the proportion of those who have been pregnant was 77.2% and the proportion of those who have experienced spontaneous abortion was 24.1%. Those who have ever experienced two or more spontaneous abortion showed higher, though not statistically significantly higher. scores for PWI. In conclusion, dysmenorrhea was associated with high stress score in two groups. And the other factors related to higher score of PWJ were different between unmarred and married women, which should be considered in a management plan for mental health promotion.

BACKGROUND: Large amounts of antigen may produce false low values on immunoradiometric assays due to the so-called high-dose hook effect. The physicians' awareness of the possibility of the "high-dose hook effect" will prevent preoperative misdiagnosis. The study was designed to identify the frequency and clinical features of patients with pituitary macroadenomas in whom a high-dose PRL hook effect was documented. METHODS: Our retrospective study involved 42 patients with non-functioning pituitary adenomas (tumor diameter >30mm) who underwent transsphenoidal microsurgery from between Jan 1999 to Aug 2004, and 6 patients with non-functioning pituitary adenoma(tumor diameter>30mm) were selected for prospective study from Sep 2003 to Feb 2004. Our retrospective study also involved 13 patients with macroprolactinoma for the comparison of the clinical features. RESULTS: 1) The presence of a high-dose hook effect was retrospectively suggested when the PRL levels increased in 4 out of the 42 patients with non- functioning adenomas(tumor diameter >30mm) after surgery. Post-operative immunohistochemical staining of their pituitary specimens revealed the tumors to be prolactinoma. 2) Prospectively, dilution testing of the specimens obtained before surgery was done in the 6 patients, and one patient presented with a case of the hook effect. The patient's prolactin level was measured at 53.1ng/mL before dilution and this was increased up to 22,600ng/mL upon the 1:1000 dilution. 3) Conclusively, the hook effect was seen in 5 of the 48 patients(10.4%) with non-functioning pituitary adenoma(tumor diameter >30mm) 4) Compared with other 2 patient groups(the macroprolactinoma(N=13) group, and the non-functioning pituitary tumor(N=43) group), the high-dose PRL hook effect is more likely to be observed in male patients with large pituitary tumors. CONCLUSION: In order to avoid the high-dose hook effect, PRL should be assayed at 1:100~1:200 or even higher dilutions of serum from all patients(and especially the male patients) with large pituitary tumors

BACKGROUND: Increased body fat, abdominal obesity and insulin resistance are important clinical features in hypogonadal men. Several studies have demonstrated that a low testosterone concentration in men is associated with coronary heart disease, visceral obesity and insulin resistance. In this study, the effects of testosterone replacement therapy on the abdominal visceral fat and cardiovascular risk factors in hypogonadal men were investigated. METHODS: We selected 26 men with secondary hypogonadism (mean serum testosterone+/-SD 0.39+/- 0.57ng/mL), who were then treated with testosterone for 12 months. We measured the body composition, including the abdominal visceral fat area by abdominal CT at the L4 level, both before and 12 months after treatment, and the lipid profile, fasting plasma insulin, HOMA-IR and the serum homocysteine, CRP and IL-6 before and 6, 12 months after treatment. RESULTS: With respect to the body composition, the lean body mass had significantly increased 12 months after treatment(P= 0.002), but there were no significant changes in the body fat mass and abdominal visceral fat area. There was a trend toward a decreased fasting plasma insulin and HOMA-IR, but this did not reach statistical significance. The total cholesterol had decreased significantly at 12 months(P=0.04) and the HDL cholesterol decreased significantly over the course of study(P=0.02). There were no significant changes in the serum homocysteine, CRP and IL-6 after treatment. CONCLUSIONS: After 12 months testosterone replacement therapy in the 26 men with hypogonadism, the lean body mass had increased significantly, but there was no significant change on the abdominal visceral fat during the treatment period. Testosterone replacement had deleterious effect on HDL cholesterol, but not significant effects on insulin resistance and the serum homocysteine, CRP and IL-6. These results suggest that testosterone replacement therapy may have a few adverse effects on cardiovascular diseases in hypogonadal men. However, it will be necessary to examine the long-term effects of testosterone replacement on the incidence of cardiovascular events as well as the cardiovascular risk factors in men with hypogonadism

BACKGROUND AND OBJECTIVES: Radiation therapy is one of the promising new treatment for restenosis, which is a major problem for the long-term success after angioplasty. We compared radiation therapy only and combined therapy of paclitaxel and radiation on neointimal hyperplasia after injury of rat carotid artery to see whether we can reduce the effective dosage of radiation and thus diminish untoward consequence of radiation if paclitaxel could function as a cell-cycle selective radiosensitizer. MATERIAL AND METHODS: A standardized carotid balloon catheter arterial injury was produced in 65 rats. First group was composed of a single dose of paclitaxel 1 mg/kg body weight, 2 mg/kg or 4 mg/kg, which was administrated intraperitoneally at 2 hours after injury. Second group received external radiation at doses of 2.5 or 5 Gy at 24 hours after injury. Third group was treated with combined paclitaxel-radiation: paclitaxel was injected at 2 hours after injury and then external radiation was delivered 24 hours later. At 21 days after injury, the cross-sectional area of neointima and the ratio of intima/medial area were determined from axial sections using image analysis. RESULTS: Single dose of paclitaxel had no effect in reducing smooth muscle cell proliferation. Minimum effective single dose to inhibit neointimal hyperplasia was 5 Gy. Combined paclitaxel-radiation group except subgroup with paclitaxel 1 mg/kg and 2.5 Gy radiation showed significant reduction of neointimal area compared to group with 2.5 Gy radiation. CONCLUSION: Low-dose external radiation combined with paclitaxel can more effectively inhibit smooth muscle cell pro-liferation and neointimal hyperplasia than radiation only in the rat carotid injury model.

Primary reninism is a rare cause of hypertension manifesting along with hypokalemia. A high level of plasma renin activity and a high level of serum aldosterone are the whole markers of primary reninism. Upon making the diagnosis of primary reninism, other more common causes of aldosteronism must be differentiated, such as renovascular hypertension and primary aldosteronism. Primary reninism is commonly caused by juxtaglomerular cell tumor, which is one of the curable causes of hypertension, and this can be successfully treated by conservative surgery. We report here on a case of primary reninism that was caused by juxtaglomerular cell tumor that developed in a 22-year-old female patient. She was recently diagnosed with hypertension and hypokalemia. She had markedly elevated plasma renin activity and an increased serum aldosterone concentration. Computed tomography revealed a mass located in the right kidney and selective renal vein sampling suggested that the mass was secreting an excess of renin. Right nephrectomy was done and her hypertension with hypokalemia was successfully treated. We report here a case of primary reninism that presented with juxtaglomerular cell tumor along with a review of the literature

BACKGROUND AND OBJECTIVES: Despite significant improvement in the field of angioplasty, restenosis remains a major obstacle to the long-term success of the procedure. Radiation can effectively inhibit neointimal hyperplasia by causing the arrest of mitosis during cell division and limiting proliferation by reducing the number of regenerating clonal progenitors. Balloon injury could induce the cell adhesion molecule, ICAM-1 and VCAM-1, on SMCs and regenerating endothelial cells (ECs). ICAM-1 and/or VCAM-1 may play a role in the progression of neointimal hyperplasia induced by balloon injury and external radiation may effectively inhibit neointimal hyperplasia by attenuating their expression. The purpose of this study was to examine the effect of external radiation against ICAM-1 and VCAM-1 on neointimal hyperplasia after balloon injury in rat carotid arteries. MATERIAL AND METHODS: A standardized carotid balloon catheter arterial injury was produced in 51 rats and external beam radiation with doses from 5-20 Gy were delivered in 28 rats (radiation treated group) at 24 hours after injury. To investigate the effect of the external radiation on neointimal hyperplasia, the intima area and the intima/medial area of arteries were measured at day 14 after injury. The expressions of ICAM-1 and VCAM-1 at day 2, day 7, and day 10 after injury were studied in control group and radiation treated group by immunohistochemistry. RESULTS: Means of intimal area and intima/medial ratio in radiation treated group were significantly lower than those in control group and significantly reduced with increasing radiation dosage. At day 2 after injury, medial SMCs of injury group extensively expressed ICAM-1, while it was focally expressed with 10 Gy radiation treated group. At day 7 and day 10 after injury, ICAM-1 expression on medial SMCs was attenuated and neointimal ICAM-1 expression was increased. As compared with control group, ICAM-1 expression after radiation was weak and focal just around the internal elastic lamina. At 2 days after injury, medial SMCs moderately expressed VCAM-1, which was weakly and focally expressed with 10 Gy radiation treated group. At day 7 and day 10 after injury, focal expression of VCAM-1 was noted around the internal elastic lamina, but there was no VCAM-1 expression on neointima with radiation. CONCLUSION: External radiation after carotid arterial injury may potentially inhibit SMC proliferation and neointimal hyperplasia, and balloon injury-induced or upregulated expressions of ICAM-1 and VCAM-1 may be attenuated with external radiation.

PURPOSE: We examined the effect of the dual EGFR/HER2 tyrosine kinase inhibitor, GW572016, on EGFR/HER2 receptor phosphorylation, inhibition of downstream signaling and radiosensitization in either an EGFR or HER2 overexpressing human breast cancer xenograft. MATERIALS AND METHODS: We established SCID mice xenografts from 4 human breast cancer cell line that overexpressed EGFR or HER 2 (SUM 102, SUM 149, SUM 185, SUM 225). Two series of xenografts were established. One series was established for determining inhibition of the EGFR/HER2 receptor and downstream signaling activities by GW572016. The other series was established for determining the radiosensitization effect of GW572016. Inhibition of the receptor and downstream signaling proteins were measured by the use of immunoprecipitation and Western blotting. For determining the in vivo radiosensitization effect of GW572016, we compared tumor growth delay curves in the following four treatment arms: a) control; b) GW572016 alone; c) radiotherapy (RT) alone; d) GW572016 and RT. RESULTS: GW572016 inhibited EGFR, HER2 receptor phosphorylation in SUM 149 and SUM 185 xenografts. In addition, the p44/42 MAPK (ERK 1/2) downstream signaling pathway was inactivated by GW572016 in the SUM 185 xenograft. In the SUM 225 xenograft, we could not observe inhibition of HER2 receptor phosphorylation by GW572016; both p44/42 MAPK (Erk1/2) and Akt downstream signal protein phosphorylation were inhibited by GW572016. GW572016 inhibited growth of the tumor xenograft of SUM 149 and SUM 185. The combination of GW572016 and RT enhanced growth inhibition greater than that with GW572016 alone or with RT alone in the SUM 149 xenograft. GW572016 appears to act as an in vivo radiosensitizer. CONCLUSION: GW572016 inhibited EGFR/HER2 receptor phosphorylation and downstream signaling pathway proteins. GW572016 modestly inhibited the growth of tumor in the SUM 185 xenograft and showed radiosensitization in the SUM 149 xenograft. Our results suggest that a better predictor of radiation response would be inhibition of a crucial signaling pathway than inhibition of a receptor.
