Appendicitis is one of the most common condition causing an acute abdomen in young adult population. Two-hundreds and fifty-nine cases of acute appendicitis provened by surgery and pathology during recent 2 years in Han-ll Hospital were studied and analyzed by preoperative plain abdominal X-ray. One case of barium enema was also done. The results were as follows; 1. Male fo female sex ration was 1:1. 2. In age distribution, the most commonage group was from two to four decade. (75.3%) 3. The most common clinical symptom was classical abdominal pain as86.5%. 4. The positive radiographic findings were obtained 75.7% of all cases. 5. Common radiographic findings as follows; 1) Reflex ileus on RLQ (73.7%) 2) Obliteration of Rt. psoas line (41.3%) 3) Scoliosis of lumbar spine(21.2%) 6. The most common site of appendix was retrocecal in position. (84.2%) 7. One case of appendicolith and one case of appendiceal diverticulum were demonstrated.

PURPOSE: Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We stuided correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. MATERIALS AND METHODS: 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. RESULTS: In All of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas involved in 9 cases, and other organ in 4 cases. CONCLUSIONS: The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.

PURPOSE: The purpose of this research was to develop and evaluate the effect of a mind map for relief of emotional labor and burnout among nurses in outpatient departments in cancer hospitals. METHODS: We developed a mind map to reduce emotional labor and burnout. A quasi-experimental study was used with a nonequivalent control group pretest-posttest design. Data were collected from December 2012 to April 2013. Participants were 35 nurses working in the outpatient department of a cancer hospital. The experimental group participated in the mind map program biweekly for 10 weeks. Data were analyzed using chi2-test, Mann-Whitney U test, paired t-test, and Wilcoxon sign rank test with the SPSS 21.0 program. RESULTS: The physical burnout and total burnout scores decreased significantly in the intervention group which took the mind map program. CONCLUSION: Findings indicate that the mind map is an effective intervention to reduce burnout in outpatient department nurses.

Human brain EST data provide important clues for our understanding of the molecular biology associated with the function of the normal brain and the molecular pathophysiology with brain disorders. To systematically and efficiently study the function and disorders of the human brain, 45,773 human brain ESTs were collected from 27 human brain cDNA libraries, which were constructed from normal brains and brain disorders such as brain tumors, Parkinson's disease (PD) and epilepsy. An analysis of 45,773 human brain ESTs using our EST analysis pipeline resulted in 38,396 high-quality ESTs and 35,906 ESTs, which were coalesced into 8,246 unique gene clusters, showing a significant similarity to known genes in the human RefSeq, human mRNAs and UniGene database. In addition, among 8,246 gene clusters, 4,287 genes (52%) were found to contain full-length cDNA clones. To facilitate the extraction of useful information in collected these human brain ESTs, we developed a user-friendly interface system, the Korea Brain Unigene Database (KBUD). The KBUD web interface allows access to our human brain data through three major search modes, the BioCarta pathway, keywords and BLAST searches. Each result when viewed in KBUD offers comprehensive information concerning the analyzed human brain ESTs provided by our data as well as data linked to various other public databases. The user-friendly developed KBUD, the first world-wide web interface for human brain EST data with ESTs of human brain disorders as well as normal brains, will be a helpful system for developing a better understanding of the underlying mechanisms of the normal brain well as brain disorders. The KBUD system is freely accessible at http://kugi.kribb.re.kr/KU/cgi-bin/brain.pl.

For the treatment of coarction of aorta, surgical intervention has been known as a standard therapy.During last decade balloon angioplasty for coarctation of the aorta has been reported as a successful and safe procedure in about 300 cases. This angioplasty was done mainly in infants and children, and little cases in adults and adolescents. A 22 year-old adult with coarctation of aorta have recieved balloon angioplasty. He visited to emergency room due to severe headache and the blood presure of arm was 240/130mmHg at emergency room. The blood pressure at ward was 168/92mmHg in upper extremities, 104/82mmHg in lower extrimities. His aortogram showed coarctation of thoracic aorta below left subclavian artery. The pressure gradient beween ascending aorta and right femoral artery was decreased from 60mmHg to 0mmHg after balloon dilatation (2 times, balloon diameter 18mm). There were no significant complications. The follow-up magnetic resonance image in 4 month after balloon angioplasty showed no evidence of restenosis or saccular aneurysm. Initial hypertension turned to normal blood pressure in 4 months after balloon angioplasty. This adult case of successful balloon angioplasty for coarctation of aorta is the first case reported in Korea.

PURPOSE: To evaluate the usefulness of cerebral blood flow measurement applied to perfusion weighted image with short-scan time single shot gradient echo-planar technique in measuring cerebral blood volume(rCBV) of normal rabbits. MATERIALS AND METHODS: With 2.1-3.6 kg weighted rabbits, image is acquired when they are in supine position in children positioner. Perfusion weighted image is acquired to 44 seconds per 1 second successively. After 4 seconds later, Gd-DTPA 2ml are injected into int. jugular vein with 2 ml per second and normal saline is also injected after that. Same technique is applied 2 times per 30 minites in same rabbit. After Image is obtained in two part of cerebral cortex at vertex, convexity, in one of basal ganglia with choosing about 3-5mm2 areas. Curve of signal intensity changes in time sequence is drawn. After this images are transmitted by PC and software IDL, regional cerebral blood volume is measured with imaging processing program made by us. RESULTS: With 22 of 24 rabbits, satisfactory 1-2 signal intensity versus time curve is made. Cerebral blood capacity and contrast media stay time (ST) is measured in two cerebral cortex and basal ganglia refering in parietal cerebral cortex. Mean focal cerebral blood flow capacity ratio in cortex was 0.97+/-0.35 and in basal ganglia, 0.99+/-0.37, mean contrast media stay time in cortex was 9.83+/-1.63 sec and in basal ganglia, 9.42+/-1.14 sec, but there was no statistically significant difference between two areas (p=0.05). CONCLUSION: In cerebral cortex and basal ganglia, there is no difference in mean focal blood volume and mean contrast stay time. Therefore, PWI is useful in cerebral blood flow and early diagnosis, prognosis of cerebral ischemic disease. Hereafter, it is helpful in analysing cerebral blood flow changes with comparison difference in rCBV between normal tissue and ischemic tissue, and that with DWI finding in infarcted patient.
