Accessory renal artery (ARA) is a kind of developmental anomaly in renal artery. It is important in respect to clinical medicine, for example primary hypertension, renovascular disease, inferior vena caval obstruction, ureteral obstruction, occurrence of other vascular anomalies such as accessory renal veins, surgical importance and renal transplantation. However, up to few research of ARA was reported in dissection of cadavers. In our dissecting theater, 12 accessory renal arteries for 10 cadavers were found during dissection the 22 cadavers from 1995 to 1996. 1. Two cases were bilateral and 8 cases were unilateral accessory renal arteries. 2. Seven cases were left and 5 cases were right accessory renal arteries. 3. Two cases originated at the abdominal aorta between celiac trunk and superior mesenteric artery, 7 cases originated between superior mesenteric artery and inferior mesenteric artery, and 3 cases originated below inferior mesenteric artery. 4. Seven cases have no branches during their courses, 4 cases have 3 branches, and a case has 2 branches. 5. Seven cases entered into renal parenchyma through renal hilum, 5 cases entered into apical and arterosuperior segments, and 6 cases entered into inferior segment.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major pathogens of nosocomial infections. Especially in intensive care units (ICUs) and nasal carriage of Staphylococcus aureus has been known as a major risk factor of staphylococcal infections. In Korea, MRSA is the most common pathogen of nosocomial infections in ICUs. We performed this study to investigate the effects of conventional control measures and the additional effect of intranasal fusidic acid in prevention of MRSA nasal carriage and infection in ICUs of one educational hospital in Korea. METHOD: All patients admitted to medical ICU and surgical ICU in Samsung medical center from April to September 1999 were studied prospectively. Surveillance culture was done in all patients and health care workers by nasal swab culture. We tried to control MRSA infection by conventional methods in the first period April-June 1999) and by additional intranasal fusidic acid application in the second period (July-September 1999) RESULTS: Comparing the first with second periods, new nasal MRSA colonization rate among patients was significantly decreased from 14.8% to 1.8% in surgical ICU (P=0.016). Although there was no statistical difference between the first and second periods in medical ICU (14.6% vs 5.9%, P=0.192), the new nasal colonization of the first period was significantly decreased than that of the previous study which was performed in 1996 (14.6% vs 36.2%, P=0.015). And new MRSA infection rate was much more decreased than the previous study, but there was no statistical significance (11.7% vs 2.0%, P=0.066). CONCLUSION: Conventional methods for MRSA control decreased new MRSA nasal colonization of patients in ICUs. Application of intranasal fusidic acid was considered as an additional control measure for reducing MRSA nasal colonization. For evaluating effect of intranasal fusidic acid for preventing of MRSA infection in ICUs, further study with larger scale of study population is warranted.

Cloacal anomaly is an extremely rare congenital malformation results from a failure in the development of the urorectal fold that separates the rectum from uterovaginal tract. It is characterized by the presence of a single duct where the gastrointestinal, genital and urinary tracts join. It presents with highly variable forms, which make it difficult to be diagnosed antenatally. We report a case of cloacal anomaly confirmed with autopsy, which was initially detected by the presence of a huge cystic fetal abdominal mass by ultrasound at a 22 weeks of gestation.

To investigate fragile sites induced by aphidicolin which is a specific inhibitor of eukaryotic DNA polymerase a which is primarily associated with chromosomal DNA replication in human lymphocytes, HaCat cells (human keratinocytes) and MRC-5 cells (human embryonic lung fibroblast), we cultured each cells in RPMI 1640 with 10% fetal calf serum and 2% PHA. Treatment of the cells with aphidicolin was generally carried out for the last 24 hours of culturing. The drug was dissolved in DMSO and used at final concentrations of 0.05~0.15 mg/ml, corresponding to a maximum DMSO concentration of 0.028%. Karyotypes of each cells were performed by routine method, and 50 metaphases were scored for each culture for analysis of breakage rate. Experimental cells treated with APC showed a dose dependent sensitivity and the amounts of chromosome breakage induced by APC are the highest in concentration of 0.15 mg/ml. The frequency of fragile sites on each cells appeared in MRC-5 cells, lymphocytes and HaCat cells in order. The common fragile sites on all experiments was 16q23, and the common fragile sites on embryonic cells was 1p31. It can be concluded that gene or nucleic acid which is located on 16q23 is the most important factor to induce chromosomal breakage with sensitivity to aphidicolin and 1p31 is important site to induce chromosomal breakage in embryonal cells.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about 'Table etiquette', 'Reasons for eating fruits and vegetables'(78.7%), 'Food waste and environment'(72.3%), 'Healthy snacks'(55.7%), 'Food sanitation'(52.3%), 'Food culture of foreign countries'(48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about 'basic food preperation'(p < 0.01). They had learned 'Nutrients for body'and 'Food waste and environment'in school, 'Healthy weight loss', 'Food culture of foreign countries', 'Food circulation'on television, Most content ('Table etiquette', 'Simple cooking', 'Food sanitation', 'Eating behaviors for health', 'Reasons for eating fruits and vegetables', 'Healthy snacks') was learned from parents. The practice after nutrition education was higher in 'Table etiquette'(2.14), 'Eating fruits and vegetables'(2.07) than others compared with education experience. The most reason of non-practice on nutrition information was 'Troublesome'. In 'Nutrients for body', a boy answered 'Difficult for practice'20.0%, a girl answered 'Difficult to understand'32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the 'Nutrients for body'(49.6%), 'Food sanitation'(44.5%) because of 'important content', 'Basic food preparation'(40.6%), 'Food culture of foreign countries'(36.3%) because of 'interesting content', 'Healthy weight loss'(52.0%), 'Eating behavior for health'(44.5%) and 'Healthy snacks'(33.7%) because of 'need for my health'.

Splenic marginal zone lymphoma (SMZL) is a rare B-cell neoplasm characterized by massive splenomegaly, moderate lymphocytosis, bone marrow intrasinusoidal involvement of lymphocytes and a relatively indolent course. We report a case of SMZL diagnosed by bone marrow studies using immunophenotyping and immunohistochemical stain, and confirmed by splenectomy. The patient was a 61-year old male, who showed mild lymphocytosis in peripheral blood and bone marrow aspirates. Immunophenotyping of bone marrow aspirates showed lymphocytes positive for CD19, CD20, CD22 (dim), CD23 (dim) and negativie for CD5 and CD10. The immunohistochemistry of bone marrow and spleen also showed lymphocytes positive for CD20 and negative at for cyclin D1. Now he is being treated for chronic obstructive pulmonary disease and will receive chemotherapy.

A case of simultaneous bilateral tubal pregnancy following in-vitro fertilization and embryo transfer is presented. On the 22 days after ET, the patient complained of low abdominal pain and vaginal spotting for one day and was suspected of left tubal pregnancy by transvaginal ultrasonography. However, laparoscopy revealed the bilateral tubal pregnancy and laparoscopic bilateral salpingectomy was performed. This unusual type of ectopic pregnancy must be kept in mind when evaluating a patient suspected of a possible early abnormal gestation after assisted reproductive technologies. It is critical to perform a close inspection of the abdomen, pelvis, and contralateral tube during surgery.
