Matrix metalloproteinases (MMPs) play an important role in the normal morphogenesis, maintenance, and repair of matrix and also have important functions in pathologic conditions characterized by excessive degradation of extracellular matrix, such as rheumatoid arthritis, osteoarthritis, periodontitis and in tumor invasion and metastasis. In this study, expression of MMP-1 and -2 mRNA in retrodiscal tissue of the temporomandibular joint (TMJ) was examined and compared with magnetic resonance imaging (MRI) and surgical findings. MMP mRNAs in the retrodiscal tissue samples were detected by reverse transcription - polymerase chain reaction. TMJ internal derangement (ID) was categorized as normal disc position, disc displacement with reduction, early stage of disc displacement without reduction (DDsR) and late stage of DDsR. TMJ osteoarthrosis (OA) was classified with normal, mild and advanced OA. The amount of synovial fluid collection was divided into not detected, small, large and extremely large amount on MR T2-weighted imaging. Perforation and adhesion were examined during open surgery of the TMJ. Six out of 37 samples were excluded because of little amount of extracted total mRNA. MMP-2 mRNA was detected whole joints, and so the MMP-2 mRNA seems to be expressed normally in retrodiscal tissue. However, MMP-1 mRNA was expressed in 8 of 31 joints. Frequencies of MMP-1 mRNA expression according to the TMJ IDs, amount of synovial fluid and surgical findings made no significant difference. MMP-1 mRNA was detected more frequently in OA groups (7/16 joints, 43.8%) than in normal bony structure group (1/15,joints, 6.7%). Expression of MMP-1 mRNA in retrodiscal tissue might be related with OA of the TMJ.

PURPOSE: This study has examined effectiveness of a secondhand smoking prevention program for adolescents. METHODS: The study was done in a nonequivalent control group pretest/posttest design. The subjects of the current study were 198 middle school students from K city in the Gyeongbuk province. The students were assigned to an experimental group (100) and participated in the secondhand smoking prevention program or to a control group (98) and did not take part. Data collection was done from June to July 2012. A Chi-square test, independent t-test, paired t test and ANCOVA were used with the SPSS 18.0 program for data analysis. RESULTS: There were significant differences between the groups in knowledge of short-term influence of secondhand smoking (F=9.65, p<.005), knowledge of long-term influence of secondhand smoking (F=15.53, p<.001), verbal coping skills for secondhand smoking prevention (F=16.35, p<.001), behavioral coping skills for secondhand smoking prevention (F=8.49, p<.005), and assertiveness of secondhand smoking prevention (F=17.30, p<.001) measurements. CONCLUSION: The secondhand smoking prevention program delivered to the adolescents is an effective method of encouraging secondhand smoking prevention and can be utilized as an effective nursing intervention for adolescents.

End-stage renal disease(ESRD) is the fatal retention of non-volatile, metabolic waste products, salt, and water due to extensive loss of functioning nephrons. Renal replacement therapy is primarily aimed to remove retained waste products and fluid. Adequacy of dialysis is the dose of dialysis below which one observes a significant worsening of morbidity and mortality. Urea kinetic modeling, Kt/Vurea, etc. is regarded as a quantitative guideline of dialysis adequacy in both hemodialysis(HD) and peritoneal dialysis(PD). Water is one of the most important uremic toxin retained in ESRD patients. The importance of fluid overload on morbidity and/or mortality in dialysis patients is yet to be evaluated. Recent technology of HD provides adequate Kt/ Vurea for relatively short dialysis time and higher patient survival. Blood pressure control and extracellular fluid(ECF) volume are closely related with dialysis time in HD patients. Short dialysis time, 3-4 hours per session may not enough to control blood pressure. Hypertension is an important risk factor of survival in dialysis patients. Fluid overload is the most important factor of hypertension in dialysis patients. Patients with uncontrolled hypertension have higher mortality rate despite similar Kt/Vurea compared with patients with good blood pressure control. A longer dialysis time improves ECF volume and blood pressure control and decreases cardiovascular mortality. Continuous ambulatory peritoneal dialysis(CAPD) is a slow continuous therapy and is believed to maintain better control of ECF volume and blood pressure compared with hemodialysis. ECF volume and blood pressure controls are improved after initiation of CAPD, however, return to pre-CAPD levels after a few years of CAPD when residual renal function disappears. Patients transferred to hernodialysis from CAPD lose around 4kg of body weight for a few months on HD. Approximately 25% of CAPD patients are clinically fluid overloaded. Increased peritoneal permeability is an independent risk factor for patient and technique survivals in CAPD patients. Fluid overload in CAPD patients with increased peritoneal pernability is believed to be an important underlying mechanism of increased mortality and technique failure in this group. In conclusion, fluid overload is an important risk factor of mortality in dialysis patients. Sufficient dialysis time resulting good controls of ECF volume and blood pressure in hemodialysis patients and individualized dialysis prescription according to the peritoneal permeability in CAPD patients are vital to provide adequate dialysis and to decrease cardiovas-cular mortality.

Protein energy malnutrition occurs when inadequate protein and calories are ingested. PEM is not confined to children and is common in hospitalized patients. PEM is diagnosed by a weight loss and hypoalbuminemia. We report a case of PEM in a 27-year-old man after Whipple's operation. He had brittle hair, loss on the scalp and brownish colored papules with desquamation on extremities. Also he had erosion and fissuring on the perioral area and beef tongue. Treatment with zinc sulfate, albumin and vitamin resulted in a good response.

Mycosis fungoides is an unusual malignancy of helper T-lymphocyte origin which presents initiaily with skin disease and progresses to the lymph nodes, peripheral blood. and viseral organs, and frequently results in death. A 51-year-old woman was admitted to the hospital in October, 1930 for the evaluation of a painful reddish brown tumor with ulceration of 6 months duration on the abdomen. Lymphadenopathy was not present, and routine laboratory examinations revealed negative or, within normal limits. She was diagnosed as mycosis fungoides with stage IIb according to the commirtee on staging and classification of cutaneous T-cell lymphoma, and treated with chemotherapy;regimen, BAM-M consisted of Bleomycin, Adriamycin, Methotrexate and topical nitrogen mustard. she achieved complete remission of the tumor with five cycles of BAM-M chemotherapy. We report favorable response after BAM-M chemotherapy in a pacent with advanced stage of mycosis fungoides(TNM IIb).

Purpose: This study was conducted to determine factors influencing changes in the self-esteem of multicultural adolescents over time. Methods: A longitudinal design was adopted to analyze secondary data. This study used the 2nd, 4th, and 6th year data of Multicultural Adolescents Panel Study (MAPS) collected by the Korea Youth Policy Institute. The linear mixed model was utilized to analyze self-esteem changes over time. Results: The factors of sex and age of the students, the mother’s Korean writing ability, and the Filipino or Japanese mothers had a significant effect on the self-esteem change of multi-cultural adolescents over time. Specifically, it was found that female students’ self-esteem was decreased by 0.04 (t=-2.39, p=.017) more than male students over time. As the subject’s age and mother’s Korean writing ability increased, self-esteem was decreased by 0.01 (t=-2.53, p=.011) and 0.03 (t=-2.52, p=.012) over time. In addition, compared to that of those who had mothers from Korea, self-esteem of those who had Filipino or Japanese mothers was decreased by 0.04 significantly. Conclusion Therefore, when developing a self-esteem promotion program, it is necessary to develop content by reflecting the characteristics of mothers as well as the gender and age of students. Furthermore, the significance of this study is in that it established a foundation for a positive self-identity of multicultural adolescents whose number is increasing recently by identifying factors affecting their self-esteem.

Animal models for human chronic pain syndromes were developed and widely used for pain research. One of thsese neuropathic pain model by Kim and Chung[1992] has many advantages for operation and pain elicitation. We have examined the c-fos protein, substance P, CGRP immunoreactivity in dorsal root ganglia and dorsal horn in this neuropathic model. About 50 Sprague-Dawley rats were used for this study. L5 and L6 spinal nerve were ligated tightly to produce neuropathic pain model. After 2, 4, 8, 16, 24 hours and 1 week of surgery, rats were anesthesized and sacrificed by perfusion through the left ventricle with saline followed by 0.1M phosphate buffer[pH 7.4] containing 3% paraformaldehyde, 3% glutaraldehyde, and 0.1% picric acid. After confirmation of the roots transected by the surgery, the L5 and L6 dorsal root ganglion and spinal cord were removed and processed for immunohistochemistry. All tissue sections were immunohistochemically stained for substance P, CGRP and c-fos by using the peroxidase-antiperoxidase[PAP] method. Count the number of immunostained substance P and CGRP dorsal root ganglion cells and c-fos immunoreactive dorsal horn cells and analyzed statistically with Mann-Whitney U test. The results are as follows. 1. The number of c-fos protein immunoreactive neurons in the superficial layer of dorsal horn were increased markedly at 2 hours after operation, gradually decreased to normal level 1 week after operation. 2. The number of c-fos protein immunoreactive neurons in the deep layer of dorsal horn were gradually increased to the peak 24 hours after operation, decreased to normal level 1 week after operation. 3. The number of substance P and CGRP immunoreactive L5 and L6 dorsal root ganglion neurons were decreased markedly at 1 week after pain model operation. In conclusion, after neuropathic pain model operation, c-fos protein were immediately expressed in the superficial layer of spinal dorsal horn, thereafter c-fos protein in the deep layer of spinal dorsal horn were expressed. CGRP and substance P immunoreactive neurons were decreased markedly 1 week after neuropathic pain model operation.

BACKGROUND: There is a substantial evidence that anatomical connections and functional interactions exist between vestibular and autonomic systems. The nature of these interactions, however, is complex and has not been fully defined. Heart rate variability (HRV) was used to investigate the physiological role of the vestibular system on control of heart rate. METHODS: HRV including mean, standard deviation, coefficient of variation (CV), power spectrum was analyzed from R-R intervals of ECG during vestibular stimulation in rabbits. RESULTS: Urethane anesthesia increased heart rate and maintained regular R-R intervals, however, low frequency region/high frequency region (LF/HF) was not changed. In anesthetized rabbits, electrical stimulation of the vagus nerve decreased heart rate and decreased LF/HF by increasing HF. On the contrary, electrical stimulation of the cervical sympathetic nerve increased heart rate and increased LF/HF by increasing LF. Atropine, cholinergic blocker, increased heart rate and increased LF/HF by reducing HF, and propranolol, beta-adrenergic blocker, decreased heart rate and decreased LF/HF by reducing LF. In unanesthetized rabbits, stimulation of the vestibular system induced by rotation or caloric increased heart rate and increased LF/HF by increasing LF. Also electrical stimulation of the vestibular nerve produced the same effects as rotation or caloric in anesthetized rabbits. CONCLUSION: These results suggest that stimulation of the vestibular system increased heart rate not by inhibiting the parasympathetic nerve but by activating the sympathetic nerve.

Although malignant melanoma usually occurs after the diagnosis of vitiligo-like depigmentation, the latter is rarely followed by the former. We herein report on such a case in which recognition of the vitiligo-like depigmentation preceded diagnosing the metastatic melanoma by several months. A 56-year-old woman had first developed vitiligo-like depigmentation on the forehead, eyelids, neck and back 18 months previously and thereafter she detected a hard mass in the left axilla 2 months previously. Based on the histologic findings, the axillary mass was diagnosed as metastatic melanoma. To evaluate the primary tumor focus, thorough examinations that included PET-CT, bone scan and sigmoidoscopy were performed, but we couldn`t find any the original primary tumor. Our case suggests that the vitiligo-like depigmentation could be a sign that heralds metastatic melanoma.
