The aim of this study was to characterize the morphology of a polycystic kidney which was found in 100% of the transgenic mice homozygous for inv mutation and to gain insight into the pathogenesis of inherited polycystic kidney disease during the pre- and postnatal periods. The fetal and postnatal kidneys from the homozygous and heterozygous transgenic mice were examined by the light, transmission and scanning electron microscopes, image analyzer, and an immunohistochemistry utilizing the antibodies specific for each segment of the renal tubules (Tetragonolobus purpureas, Arachis hypogaea, Tamm-Horsfall protein, AE1/AE3, EMA, vimentin, Phaseolus vulgaris) was performed to determine the site of origin of renal cysts. Two developmental phases of a cystic disease were identified. The first phase, seen in fetal kidneys, was characterized by dilatation mainly of the proximal tubules and a few distal tubules. The later phase, in postnatal period, was characterized by progressive enlargement of the kidneys due to mainly cystic change of the collecting ducts, which distorted the normal architecture of both cortex and medulla and almost completely replaced the renal parenchyma. The cystic dilatation involved all segments of the nephron and the collecting duct as well as the Bowman's spaces of glomeruli. The epithelial cell hyperplasia was found as a micropolyp formation within the renal cysts and an increase in PCNA positive cells. These findings suggest that a cyst is not simply a ballooning of a renal tubule and the stretching of cells, formerly thought to be due to an altered compliance of an abnormal basement membrane, but indeed the result of increased numbers of tubular epithelial cells.

Generalized pustular psorissis which is originary described by von Zumbusch in 1910, is the most intense form of the acute exanthematic variant among psoriasis and it is to be occured as a rare disease. We presented a case of generalized pustular psoriasis of a 16 year-old girl, who suddenly developed wide spread pustules during the acute exacerbating course of the psoriasis which had started from the primary plaque on her left anterior chest one month ago. She was free from subjective symptom. As the objective sign, the leukocytosis was only one of the significant laboratory findings. All skin lesions were almost eleared by the oral administration of methotrexate in 3 months.

Adenoid cystic carcinoma of the major salivary gland is a relatively rare tumor which is well known for its high local recurrence rate and frequent distant metastasis. Metastasis of this tumor to kidney has not been reported previously to our knowledge. We report two cases of renal metastasis from adenoid cystic carcinoma of the salivary gland.

The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

This retrospective study comprised patiens with facial bone fractures in various accidents and treated in the department of Plastic and Reconstructive Surgery, Pildong hospital, Chung Ang university during the past 5 years from January 1994 to December 1998. The medical records of these patients (fractures) were reviewed and analysed in order to gain insight into a clinical pattern and understnad the therapeutic modalities. The following results were obtained: 1. The monthly incidence was highest in August and most common accident time was between 6:00 p.m and midnight. 2. The mean age of patients was 28.3 years, and age range was 3 to 69 years. The most prevalent age group was the third decade of life (42.9%). Males predominated more than female in the ratio of 4.1:1. 3. The most common etiology was assault (29.6%) followed by traffic accidents (28.5%), fall (23.1%), sports (7.9%). 4. 369 facial fractures in 277 patients were classifed. The most common sites were nasal bone, followed by zygoma, mandible, maxilla, orbit. 5. Associated soft tissue injuries were combined in 168 patients (60.6%), and fractures other than facial bone were developed in 61 patients (22%). 6. Treatment of facial bone fracture consisted of open reduction (42.6%), closed reduction (40.1%), and conservative treatment (17.3%). 7. The complication rate was 11.6% and the most common complication was the eye problem.

Since the introduction of Holdsworth's new classification on fracture-dislocations of spine with particular emphasis on the role of posterior ligmaent complex, operative reduction and spinal fusion is considered to be an established procedure in treating unstable injuries of the thoracolumbar spine.By stabilizing unstable fractures,nursing, and rehabilitation become much easier. Among the various methods and devices, Harrington instrumentation and posterior spinal fusion have been used and found to be acceptable in our series. Twenty five consecutive patients with unstable fractures and fracture-dislocations' of thoracolumbar spine were treated by open reduction and spinal fusion with Harrington rod fixation at the Department of Orthopedic Surgery, Kang Nam General Hospital Public Corporation from the period of 1982 to 1985. The following results were obtained from analysis of the cases. l. Among 25 cases, 15 (60%) were due to flexion-rotation violence, 5 pure flexion,3 vertical compression, 1 shear fracture respectively. 2. Among 16 cases with neurologic deficit, 15 cases showed considerabel improvement after surgery. 3. Most of the cases showed satisfactory bony fusion, and average postoperative kyphotic angle was 14.4 after 3 months. 4. Although no particular external fixation was adopted, permitting mobility in bed, postoperative correction was relatively well maintained.
