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.

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.

BACKGROUND: Although native radiocephalic arteriovenous fistula provides the best possible vascular access for hemodialysis, available veins for this fistula are limited. Ulnobasilic arteriovenous fistula (UBF) is alternative method for native fistula of forearm. But this method is not commonly used because detection of the vein is difficult and cannulation for hemodialysis id uncomfortable. This study was performed to evaluate clinical usefulness of UBF. METHODS: From June 1999 to April 2000 and from September 2001 to February 2002, 256 arteriovenous fistulae were made in 239 patients with chronic renal failure and among them, 26 UBF were made by one surgeon. At April 2002, a total of 26 UBF were reviewed. RESULTS: The results were as follows : There were 17 men and 9 women, aged 31 to 72 years. There were 7 diabetic patients. 22 patients of them had previous history of arteriovenous fistula operation. There were six failures : one delayed occlusion; one venous hypertension due to proximal stenosis during hemodialysis; four inadequate maturation. The 20 patients showed good patency. CONCLUSION: This study shows that UBF can be useful method in patients with failed radiocephalic arteriovenous fistula or poor cephalic vein and preserve upper arm vein for future operation.

The cardiovascular and CNS effects of MIDAZOLAM 0.25 mg/kg were studied in 40 patients, randomised and emergency operations(20 males and 20 females). The effects of the administration of MIDAZOLAM intravenously on the cardiovascular and central nervous system were determined. The results were as follows: 1) It had short duration of action and absence of vascular irritation compared with MIDAZOLAM. 2) Three minutes after injection, mean systolic pressure decreased from 132+/-16 mmHg to 115+/-18 mmHg and diastolic pressure from 87+/-11mmHg to 77+/-13 mmHg. One minute after injection heart rate increased from 89+/-19 beat/min to 95+/-20 beat/min and after three minutes returned to prior level. 3) Our study shows that the intraveous administration of MIDAZOLAM 0.25mg/kg produces. a statistically significant, but clinically unimportant, decrease in blood pressure and an increase in heart rate. 4) The effects of MIDAZOLAM on the central nervous system were determined from the time of onset of injection. Spontaneous eye closure, loss of eyelash reflex and apnes were observed at 113+/-66 sec, 133+/-65 sec, and 147+/-58 sec, after injection of MIDAZOLAM. 5) MIDAZOLAM as an induction agent for anesthesia is not indicated for in out-patient surgery due to the extended duration of drowsiness losting over 3 hours in the recovery room. 6) MIDAZOLAM was sufficient as an induction agent for general anesthesia.

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.
