We have experienced 113 cases of neonatal sepsis comfirmed by clinical manifestations and blood cultures from Jan. 1988 to Dec. 1992 at the Neonatal Intensive Care Unit of Ulsan Dong-Kang Hospital and observed the incidence, predisposing perinatal factors, clinical manifestations, associated illnesses, laboratory findings, isolated microorganisms, antibiotics sensitivity test and mortality rate of neonatal sepsis according to onset of disease. The result were as follows: 1) The incidence of neonatal sepsis was 1.39% and male to female ration was 1.38:1. The incidence and sex difference between early onset and late onset disease were not significant. 2) Neonatal sepsis was more prevalent in premature infants (2.47%) than in fullterm infants (1.28%) and nore prevalent in low birth weight infants(3.01%) than in normal birth weight infants (1.25%). In premature infants, neonatal sepsis was more prevalent in early onset (63.2%) than in late onset diease (36.8%). In low birth weight infants, neonatal sepsis was more prevalent in early onset (64.8%) than in late onset dieases (35.7%P). 3) Predisposing perinatal factors, such as meconium staining, birth asphyxia, difficult delivery, premature rupture of membrane, maternal infection, toxemia and postpartum bleeding were slightly frequent in early onset disease. 4) Among the clinical manifestations, jaundice, respiratory symptoms, pallor, lethargy, poor feeding and hepatosplenonegaly were slightly frequent in early onset disease, but temperature instability and gastrointestinal symptoms were slightly frequent in late onset disease. 5) Among the associated illness, pneumonia, disseminated intravascular coagulopathy, amnionitis, hyaline membrane disease and osteomyelits were more common in early onset disease, but gastroenteritis, urinary tract infection, necrotizing enterocolitis, wound infection and meningitis were mors common in late onset disease. 6) The difference of laboratory findings between early onset and late onset disease was not significant. 7) Causative organisms were gram positive organisms in 87 cases(77.0%), gram negative organisms in 22 cases (18.6%) and mixed infections in 5 cases (4.4%). Among them, coagulase negative staphylococcus was the most common one and staphylococcus aureus was the second. The incidence of infections caused by coagulase negative staphylococcus and staphylococcus aureus, between early onset and late onset disease, was not significantly different. Streptococcal infection was more prevalent in early onset disease, especially all group B streptococcus caused early onset disease. 8) Gram positive organisms ware sensitive to Cephalothin (92.9%), Chloramphenicol (90.0%) and Ceftriaxone (88.9%). Gram negative organisms were sensitive to Amikacin (91.3%) and Colistin (82.6%). The difference of antibiotics sensitivity for organisms causing early onset and late onset diease were not significant. Gram negative organisms causing early onset disease were resistant to gentamicin and terramycin, but those organisms causing late onset disease were more sensitive to gentamicin (88.9%) and tobramycin (77.8%). 9) The mortality rate was 7.96%. It was higher in gram negative infections (23.8%) than in gram positive infections (4.6%). No significant difference of mortality rate between early onset and late onset disease was found.

PURPOSE: This study was conducted to analyze the association between health literacy and health behavior and the effect of health literacy on health behavior in late school-age children. METHODS: Data were obtained from 333 participants who were 5th and 6th-grade students sampled from 8 elementary schools in Busan. Rapid Estimate of Adolescent Literacy in Medicine (REALM-Teen) and Newest Vital Sign (NVS) was used for assessing linguistic and functional health literacy, and the health promotion behavior score was measured for health behavior. RESULTS: The percentage of those with limited linguistic and functional health literacy was high (47.1%, 56.8%). Linguistic health literacy (r=.38, p<.001) and functional health literacy (r=.11, p=.048) had a correlation with health behavior. Health behavior was significantly associated with perceived health status (beta=1.94, p<.001), number of times of health education (beta=0.18, p<.001), academic achievement (p<.001), home literacy environment (beta=0.13, p=.016), perception of changes after health education (p=.011), and linguistic health literacy (beta=0.23, p<.001). CONCLUSION: The results of this study indicate that children with adequate health literacy are more likely to do health behaviors. Therefore, it is important to develop educational strategies to raise children's health literacy level and consequently to induce them to perform more health behaviors in daily life.

A case of diffuse malignant mesothelioma of peritoneum which was difficult to distinguish from metastatic anaplastic carcinoma or malignant melanoma was presented. The patient was a 50 year-old woman and complained of an abdominal pain and ascites for 20 days. Histologically, the tumor cells showed highly anaplastic appearance with sheet-like arrangement without any papillary or tubular structure. They stained Positive for cytokeratin and vimentin and negative for CEA, S-100 protein and melanoma associated antigen. A few cells within the tumor showed Positive reactivity to desmin. Ultrastructurally, the tumor cells had characteristic findings of mesothelioma such as long, exuberant, wavy microvilli with 10 to 12 of length/diameter ratio. The patient died 3 months after the diagnosis in spite of intraperitoneal chemotherapy.

A 42-year-old woman preseated with intermittent rectal bleeding of a week's duration. A large polypoid mass with pigmented, ulcerated, nodular surface was seen in the rectum at 3cm from the anal verge during flexible sigmoidoscopy. A histologic diagnosis of metastatic melanoma wae made on light microscopic examination of biopsies obtained at sigmoidoscopy. The presence of metastatic melanoma at sites other than the rectum was found at the skin, pleura and lung. We report a case of metastatic malignant melanoma of the rectum with the review of the literature.

Exercise testing with Thallium imaging is widely used for the noninvasive evaluation of patients suspected of having coronary artery disease. However, many patients referred for stress testing connot exercise adequately for either physical or psychological reasons, and as a result may have nondiagnostic or suboptimal test results. Intravenous dipyridamole in conjunction with Thallium imaging is as effective alternative method without exercise. But, myocardial imaging using the standard scintillation camera technique(planner view) is hampered by superposition of proximal & distal cardial walls and by the segmental nature of myocardial ischemia. For this reason, Single Photon Emission Computed Tomography(SPECT) reslut in high specificity & sensitivity rates for the detection of coronar artery disease compared with conventional technique. So we performed dipyridamole Th-201 myocardial scintigraphy on 25 subjects who have suspicious angina or myocardial infarction instead of exercise Th-201 myocardial scintigraphy, and compared SPECT view with conventional plannar view. The results obtained are as follows : 1) T1-201 scintigraphic findings in 17 patients with suspicious angina were as follows ; redistribution defect was seen in 4 cases in plannar view and 13 cases in SPECT view. 2) T1-201 scintigraphic findings in 8 patients with myocardial infarction were as follows ; in planner view, perfusion defect was seen in all cases and 1 cases of them, redistribution defect was accompained, and in SPECT view, perfusion defect was seen in all cases and 6 cases of them, redistribution defect was accompained. 3) During dipyridamole infusion, the mean systolic & diatolic pressure decreased from 133+/-22.7/86+/-13.5 to 121+/-23.9/78+/-13.1mmHg and the heart rate increased from 68+/-12.4 to 84+/-12.4beats/min. 4) Adverse effects of dipyridamole were noted in 14(56%) of the subjects, but in 12 of these, the symptoms were mild in severity and subsided spontanously. To summarize, Dipyridamole-201 myocardial imaging is a useful and test for coronary artery disease, and the new tomographic technique, SPECT view, is more useful than the conventional plannar view.

BACKGROUND: The inhibitory effects of nitric oxide(NO) on platelet adhesion and vascular smooth muscle cell(VSMC) proliferation may have a possible role inhibiting development of neointima following balloon catheter induced injury. We tested the hypothesis that L-arginine, the precursor of NO, would attenuate neointima formation following balloon catheter induced injury via regulation of antagonistic balance between proliferation and apoptosis of VSMC. METHODS: Adult, male Sprague-Dawley rats(300 to 400g) were anesthetized with ketamine (100mg/kg intraperitoneally). The left common and external carotid artery were exposed. For endothelial denudation, 2mm angioplasty catheter was introduced through the left external carotid artery into the left common carotid artery. The catheter was inflated at I atm. and withdrawn three times. Animals were randomized to receive 2.25% L-arginine in their drinking water(n=14) or placebo(n=16) from 2 days prior to and 9 days following denudation. VSMC proliferation was quantified by immunohistochemical staining with an antibody to the proliferating cell nuclear antigen(PCNA). The cells undergoing apoptosis were identified by terminal nucleotidyl transferase-mediated nick end labeling(TUNEL) method and morphologic changes by computerized planimetry and transmission electron microscopy. RESULTS: 1) The neointimal area in injured arteries were significantly reduced in L-arginine supplemented animals compared with placebo group(p<0.05). 2) L-arginine administration significantly reduced the number of PCNA positive cells in neointima when compared with placebo at 9 days(p<0.05). 3) Positive TUNEL cells were not influenced by L-arginine supplementation. 4) On transmission electron microscopy, there were no cells showing characteristics of apoptosis in neointima. CONCLUSION: These results suggested that the inhibitory effect of L-arginine on neointima formation is due to reduced VSMC proliferation, but is not due to increased VSMC apoptosis at the early time period after initmal injur .

PURPOSE: The fibrates are ligands for peroxisome proliferator-activated receptor (PPAR) alpha and used clinically as hypolipidemic drugs. The fibrates are known to cause peroxisome proliferation, enhance superoxide dismutase (SOD) expression and catalase activity. The antioxidant actions of the fibrates may modify radiation sensitivity. Here, we investigated the change of the radiation sensitivity in two cervix cancer cell lines in combination with fenofibrate (FF). MATERIALS AND METHODS: Activity and protein expression of SOD were measured according to the concentration of FF. The mRNA expressions were measured by using real time reverse-transcription polymerase chain reaction. Combined cytotoxic effect of FF and radiation was measured by using clonogenic assay. RESULTS: In HeLa cells total SOD activity was increased with increasing FF doses up to 30 microM. In the other hand, the catalase activity was increased a little. As with activity the protein expression of SOD1 and SOD2 was increased with increasing doses of FF. The mRNAs of SOD1, SOD2, PPARalpha and PPARgamma were increased with increasing doses of FF. The reactive oxygen species (ROS) produced by radiation was decreased by preincubation with FF. The surviving fractions (SF) by combining FF and radiation was higher than those of radiation alone. In Me180 cells SOD and catalase activity were not increased with FF. Also, the mRNAs of SOD1, SOD2, and PPARalpha were not increased with FF. However, the mRNA of PPARgamma was increased with FF. CONCLUSION: FF can reduce radiation sensitivity by ROS scavenging via SOD induction in HeLa. SOD induction by FF is related with PPARalpha.
