The fashion of vascular anastomosis, end-to-end or end-to-side (E-to-S), are depended upon surgeon's preference or surgical situations. In E-to-S anastomosis two different methods of arteriotomy are applicable but it has been suggested the type, either elliptical or slit arteriotomy, play a different role in the flow hemodynamics. We thought that the difference is more considerable in microvascular surgery. This study examines the effects of elliptical versus slit arteriotomy on morphologic vessel patency. Twenty male Sprague-Dawley rats were divided into two groups of ten rats each. Both carotid arteries were selected as a experimental model. During the procedures the rat brain was tolerable to ischemia and all animals were survived after operations. The morphologic analysis of anastomosis site was through resin-casting method with scanning electromicroscopic examination. The results showed notable difference between two groups in three-dimensional morphology at two-month of operation. This difference may affect the flow hemodynamics and long-term vessel patency. In microvascular anastomosis, the mortpologic difference of the elliptical arteriotomy is worse than slit arteriotomy which compromises the vessel circumference.

Dyke-Davidoff-Masson syndrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. It manifests hemiparesis, varying type seizure, and mental retardation. We experienced two cases of Dyke-avidoff-Masson Syndrome, in a 6/12 year-old boy and a 1, 10/12 year-old girl who were admitted to our department of pediatrics, because of convulsion and hemiparesis The brain CT scan showed marked dilatation of lateral ventricle, prominent sylvian fissure and cortical sulci. So we report two cases of Dyke-Davidoff-Masson syndrome with review of literature.

In this study the effect of insulin and aminoguanidine on the expression of iNOS and the development of insulitis in the multiple low dose streptozotocin (SZ) induced diabetic (LDSD) mice was evaluated. Eighty mice (Charles-River CD-1 mice) were divided into four groups. Group I received SZ for five days. Group II received SZ for five days and was followed by insulin treatment. Group III received SZ for five days and was followed by aminoguanidine treatment. Group IV was normal control group. The blood glucose level and body weight were measured weekly. On the 35th day, pancreat ic sections were observed to evaluate the frequency and the severity of insulitis in addition to the immunohistochemical expression of iNOS in the pancreatic islets. Blood glucose levels of group IV were significantly lower than other experimental groups on the 21st, 28th, and 35th day. The difference in blood glucose levels was not statistically significant. Incidence of the insulitis was lower in group II than in groups I and III. The severity of insulitis correlated with the increase in blood glucose level only in group II. The expression of iNOS was more pronounced in group I than in groups II and III. Aminoguanidine did not inhibit development of the insulitis but decreased expression of iNOS in the pancreatic islets. Therefore it is speculated that iNOS production is one of the factors and other pathogenetic mechanisms might be involved in the development of insulitis.

This study was conducted to investigate the clinical application of three-dimensional (3D) reconstructed computed tomography (CT) images in detecting and gaining information on esophageal foreign bodies (FBs). Two patients with esophageal FBs were enrolled for analysis. In both cases, 3D reconstructed images were compared with the FB that was removed according to the object shape, size, location, and orientation in the esophagus. The results indicate the usefulness of conversion of CT data to 3D images to help in diagnosis and treatment. Use of 3D images prior to treatment allows for rapid prototyping and surgery simulation.

PURPOSE: The purpose of this study was to identify effects of Artemisia A. Smoke(Ssukjahun) on primary dysmenorrhea. METHOD: This study was a pretestposttest design with a nonequivalent control group. Data were collected from May 1, 2007 to May 27, 2008. A total of 40 women with dysmenorrhea participated in the study. Among them, 20 women were assigned to an experimental group and the other 20 to a control group. Artemisia A. Smoke(Ssukjahun) was provided daily for 4 days, starting 7 days prior to next expected menses in the experimental group. The instruments used in this study included MDQ (Moos' Menstrual Distress Questionnaire) by Kim (1995), Visual Analogue Scale by Keele (1948), and PGF2alpha by urine. RESULT: The results of this study are as follows; The experimental group was lower than the control group in the degree of menstrual distress (t=5.25, p=0.000), intensity of dysmenorrhea (t=7.71, p=0.000), and prostaglandin F2alpha levels (t=4.56, p=0.000). CONCLUSION: Artemisia A. Smoke (Ssukjahun) was proved as an effective nursing intervention to reduce dysmenorrhea in young women. Its convenience and accessibility may make it a useful intervention in nursing practice and education.

PURPOSE: There is increasing necessity of using cord blood cell worldwide. In order to improve the effectiveness of cord blood's usage in Korea, the study of knowledge and attitude regarding cord blood is needed. METHODS: As descriptive correlation study, data was collected from 212 early postpartum women who stored or donated cord blood from 2007 April to July. Data was analyzed using chi-square-test, t-test, ANOVA, and logistic regression. RESULTS: Total score of knowledge and attitude of early postpartum women who donated cord blood was higher than who stored. According to the source of education and the source of influence toward decision of using cord blood, early postpartum women who educated or influenced by mass media showed difference in attitude. Job status and income, and attitude of cord blood were the predictor of cord blood donation. CONCLUSION: Attitude regard to cord blood affect to usage of cord blood, and the attitude and knowledge of cord blood in early postpartum women who donated it higher than who stored.

PURPOSE: The purpose of this study was to develop a stress measurement scale for Korean nursing students. METHODS: Sixty preliminary items were selected by classifying 229 basic items extracted via literature review and Q-sorting method. In order to verify the reliability and validity of the preliminary instrument, data were collected from 617 nursing students in 2 colleges of nursing in Korea. RESULTS: As a result of the item analysis, 58 items were selected. They consisted of 2 types of stress which were college-based stress (38 items) and clinical-based stress (20 items). Ten factors in college-based stress and four factors in clinical-based stress were extracted by factor analysis, and each had a total variance of 63.01%, and 64.93%. Cronbach's Alpha of those 58 items were .937 in college-based stress and .922 in clinical-based stress, which was high. CONCLUSION: This paper is meaningful in a way that it has developed a tool capable of measuring stress for nursing students, which reflects the characteristics of our country. It is recommended for further study to re-verify the relevance and stability of this measurement.
