The purpose of this study is to investigate the morphologic changes of the sinusoidal endothelial cells and the associated structures of the cirrhotic rat liver induced by repeat intraperitoneal injections of N-diethylnitrosamine (DEN) (100 mg/kg/week). One day to 6 weeks later, rat livers were observed under the light, transmission and scanning electron microscopy, and immunostained with laminin antibody. Two weeks after DEN treatment, the fibrillar material in Disse's space was noted, and then a basement membrane-like structure was found at 4 weeks after treatment. Laminin was detected in perisinusoidal areas after 4 weeks. Laminin was strongly positive on the fibrous septum and in the sinusoidal wall of cirrhotic nodules after 6 weeks of treatment. The diameters and numbers of sinusoidal endothelial fenestrations did not change significantly until 2 weeks. They decreased within 4 weeks, and then the sinusoidal endothelium was poorly fenestrated at 6 weeks after DEN treatment. These results suggest that as fibrosis develops in cirrhosis, the deposit of extracellular matrix such as laminin within Disse's space is a major contributing factor in the structural alteration of sinusoidal endothelial cells, and the capillarization of the sinusoidal endothelial cells may be a contributor to impairment of the hepatic function in cirrhosis.

The recent prevalence of syphilis has known to be increased progressively throughout the world, since middle of 1950. In Korea, current trend of increased syphilic infection has became a major public health problem. The authors selected sero-positive patients, among the outpaients of department of dermatology, urology, OB & GY, and physical examination, and performed statistical analysis of this sero-positive patients. Results are as following; 1) Of the 2,007 patients taken physical examination, 30 patient(1.49%) were reactive to VDRL. 2) 0.71% of the total out patients of the dermatologic dcpartment were sero-positive. Annual ratio of the syphilitic patient were increased progressively. 3) Ratio of the syphilitic patients to the total outpatients of OB & GY department was 0.55% and somewhat increased since 1976. 4) In the age distribution, the third decade shared 51.8% of the total sero-positive patients 5) In the sexual ratio. male:female=l: l. 62 in the total sero-positive patients. (male:female=l: 1.06 in the dermatologic department.) 6) In the stage distribution, latent syphilis patients were 59.14% of the total syphilitic patients.

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.

The congenital mesoblastic nephroma is the most common renal neoplasm seen in the first few months of life. This tumor usually benign, but local recurrences and metastases have been reported, and treatment is total nephrectomy. This entity must be differentiated from Wilm's tumor so as to avoid unnecessary postoperative irradiation and chemotherapy. Recently, we experienced a case of congenital mesoblastic nephroma in female newborn infant. Diagnosis was made with physical examination, plain roentgenogram of the abdomen, ultrasonography of the abdomen and I.V.P. and confirmed with microscopic examination. A brief review of the related literature was made on this subject.

PURPOSE: To assess the applicability of quantitative MR microscopy for the detection of glycosaminoglycan (GAG) depletion as an early sign of degeneration in the articular cartilage of humans treated by trypsin. MATERIALS AND METHODS: Four cartilage-bone blocks were obtained from the patient who had suffered from osteoarthritis of the knee and underwent a total knee replacement arthroscopy. Each articular cartilage segment was resected as to a round disk shape (8 mm in diameter) with a remnant of subchondral bone 1 mm in thickness. Four different culture solutions were prepared, and these solutions were 0.2 mg/ml of trypsin solution (group 1), 1 mM of Gd (DTPA) 2-mixed trypsin solution (group 2), phosphate buffered saline (PBS) (group 3), and 1 mM of Gd (DTPA) 2-mixed PBS (group 4). The cartilages were cultured and then MR imagings were performed every hour for 5 hrs, and we continued the additional cultures of 24 hrs, 36 hrs and 48 hrs. Three imaging sequences were used: T1-weighted spin echo (TR/TE, 450/22), proton density turbo spin echo with fat suppression (TR/TE, 3000/25), and CPMG (Carr-Purcell-Meiboom-Gill) (TR/TE/TI, 760/21-168, 360). MR imaging data were analyzed with pixel-by-pixel comparisons in all groups. RESULTS:The GAG loss in the articular cartilage was increased proportionately to the culture duration. Mean changes of T1 relaxation time were 1.2% for group 1, -1.9% for group 3, -54.7% for group 2 and -64.2% for group 4 (p<0.05). When comparing by linear profile on the T1-weighted images, SNR increased and T1 relaxation time decreased for group 2 and 4, as the culture duration increased (p<0.05). On the correlation analysis, there is significant correlation between GAG loss and Gd (DTPA) 2-enhancement for group 2 (p=0.0431), but there was no significant difference for group 4 (p=0.0918). More enhancement with Gd (DTPA) 2-was noted for group 2 than for group 4. Group 2 showed a diffuse enhancement in all the layers of cartilage, but for group 4, prominent enhancement was noted only in the superficial layer. CONCLUSION: Early degenerative changes of the articular cartilage were not noted on the T1-weighted images, turbo spin echo with fat suppresison and T1, T2, or the rho relaxometry by a 1.5 T machine. Only Gd (DTPA) 2- enhancement was useful in the detection of early degeneration of the articular cartilage.
