Although wound healing is a natural biologic process by which the homeostasis is preserved, the resultant hypertrophic scar or scar contracture may produce undesirable morphologic and functional sequelae. To overcome these problems, a number of attempts to produce skin substitute have been made in recent years, but none have proved to be entirely satisfactory. We compared the wound healing of full-thickness dorsal skin defects between ADM(acelluar dermal matrix)-applied wound and ADM non-applied wound group in 20 adult female Sprague-Dawley rats. The wound area was serially evaluated at 1,2,3 weeks and the difference in the mean area ratios between the two groups was then statistically analyzed using Wilcoxon rank sums test. We also performed histological evaluation of the wounds at 1,2,3 weeks. Results were as follows: 1. Experimentally produced ADM was easy to handle. Histologic findings showed no epithelium, no appendages, no cells dermal and subcutaneous layer and pure bundles of collagen. 2. The wound area ratio of ADM applied wound group was statistically larger than that of ADM non-applied(control) wound group. That is, ADM was able to inhibit the wound contraction compared with the ADM non-applied wound group. 3. In the ADM-applied group, we observed low grade exudates, no infection, fine take-up of ADM on full-thickness skin defect, gross and histologic findings of neovascularization, and progressive epithelization on ADM. These findings of biologic attachment implies the function of the ADM as a dermal substitute. These can be basis of the study on the development of artificial skin.

PURPOSE: In patient with blunt trauma of chest, supine AP x-ray cannot differenciate the lung contusion, laceration, atelectasis, and hemothorax definitely. Therefore, computed tomographic evaluation is needed for accurate evaluation of the injuries. In our knowledge, there are few reports about CT findings of blunt chest trauma, in our country, therefore we tried to fiud the characteristic CT findings in patients with blunt trauma. MATERIALS AND METHODS: We analyzed the plain x-ray and CT image of 4 patient with blunt chest trauma. Location and morphology of lung parenchymal contusion and laceration, hemopneumothorax, chest wall injuries and location of chest tube. RESULTS: Lung parenchymal contusion was noted in 53 segments. of 16 patiants'infiltration(n=27 segment), and multiple nodular pattern was noted in 15 segment, pattern of consolidation along the lung periphery was seen in 11 segment. Laceration was noted in 18 lesion and most commonly located in paravertebral area(b=8). CONCLUSION: CT scan of chest in patient with blunt chest trauma, provides accurate informations of the pattern of injuries, and localization, therefore, should be performed as po9ssible.

The skin lesions of leprosy have a great similarity to various other lesions. Fasal has called it the great imitator. Sometimes these skin lesions can b misdiagnosed because the physician does not consider leprosy. We reported a case of early lepromatous leprosy in 42 year old male. His skin lesions were similar to secondary syphilid. There were no sensory changes on the skin lesions and no enlargement of the peripheral nerves. Numerous AFB(+) bacilli from the skin smear confirmed our diagnosis of leprosy.

Closed loop onstruction represent a surgical emergency, because this lesion leads to small boweel infarction, perforation, and peritonitis if not treated in time. We analyzed the CT and ultrasonographic findings of 4 patients prospectively and 2 patients retrospectively with surgically proven closed loop obstruction of the small boweel to evaluate the characteristic findings, the cause of the closed loop obstruction and predictive criteria for the viablity of the involved bowel loop. The characteristic CT and sonographic features of the closed loop obstruction of the small bowel included; dilated fluid-filled bowel loops, the thickened bowel wall, absence of peristalsis, and ascites. In one case, closed loop obstructio originating from umbilical hernia was documented by CT and sonography. The possible criteria for the gangrenous changes could be the maximal thickness of bowel more than 7mm, and infiltration in the mesentery/omentum.

Ninety two cases of culture proved neonatal sepsis who had been admitted to pediatric department, National medical Center, during 7 years from Jan. 1984 to Dec. 1990 were reviewed clinically and the following results were obtained. 1) The frequency of neonatal sepsis was 3.1% and male to female sex ratio was 1.9:1, Sepsis was more prevalent in premature infants (9.9%) than in full term infants (1.9%). 2) The seasonal incidence was more prevalent in summer (32.6%). 3) The weight distribution showed 50 cases with the weight less than 2500 gram and 42 cases more than 2500 gram. 4) In 76 cases the onset was before 7 days old and in 16 cases were developed after 7 days old. 5) The major associated perinatal conditions in neonatal sepsis were institutional baby (23.9%), premature rupture of membranes (11.9%) and placenta previa (4.3%) in the order of frequency. The clinical manifestations on admission were jaundice (50.0%), poor activity (46.7%), respiratory difficulty (35.9%), poor feeding (22.8%), cyanosis (22.7%), gastrointestional symptoms (21.5%), fever (15.2%) and convulsion (13.0%) in the order of frequency. 6) The associated diseases were urinary tract infection (31.5%), hyaline membrane disease (19.6%), congenital disorder (18.5%), pneumonia (15.2%), anemia (13.0%), meningitis (9.8%), omphalitis (7.6%), DIC (6.5%), necrotizing enterocolitis (5.4%) and intracranial hemorrhage (5.4%) in the order of frequency. 7) Causative organisms were gram positive organisms in 27 cases (25.7%) and gram negative organisms in 79 cases (74.3%). The main organisms were Serratia marcescens (18.5%). Enterobacter spp (17.4%), Klebsiella pneumoniae (12.0%), Staphylococcus aureus (10.9%), Acinetobactor calcoaceticus (8.7%), Coagulase (-) staphylococcus (8.7%), E. coli (8.7%), Enterococcus (6.5%), Group B beta-hemolytic streptococcus (5.4%) and Pseudomonas (5.4%) in the order of frequency.
