A clinical observation was made on 19 cases of paratesticular tumors in 19 patients which were neither resolved nor improved with primary medical and conservative treatment in the Department of Urology. Capital Armed Forces General Hospital during the period from March, 1977 to July, 1981. The following results were obtained. 1. The age was ranged from 20 to 45 years old and the most favorable age was in 3rd decade. 2. The main symptoms and signs were palpable mass in 73.1%. 3. Duration of symptoms from onset was over 1 year in 57.9% and under 1 year in 42.1%. The mean duration was 17 months. 4. Organ distribution was 5 cases in epididymis, 5 in spermatic cord and 9 in scrotal tunics. 5. 11 cases arose on the left side, 4 on the right and 4 on the midline. 6. There were benign tumors in 17 (89.5%) and malignant tumors only in 2 (10.5%) of all 19 cases. These malignant lesions were developed in the spermatic cord. 7. The lesions were managed by local resection in 16 cases, orchiectomy in 2 and epididymectomy in 1.

Successful management of duodenal obstruction in newborn infant implies not only satisfactory nutrition but also achivement of normal growth. To aid early diagnosis and management, we evaluated the diagnostic methods, operative interventions and clinical characteristics of thirty-nine infants with congenital duodenal obstructions. In the 11-year period from July 1986 through June 1997, thirty-nine patients with congenital duodenal obstruction (23 males and 16 females) were treated and reviewed at the Department of Pediatric Surgery, Yeungnam University Hospital. The ratio of male to female was 1.4:1, and 29 cases(74.1%) among total 39 patients were newborn. There were 5 premature patients and 16 patients of small for gestational age. The most common causes of the congenital duodenal obstruction was malrotation (26 cases, 66.7%) and followed by annular pancreas (9 cases, 23.1%), type 1 atresia (3 cases, 7.7%) and wind-sock anomaly (1 case, 2.6%). Common symptoms were vomiting, abdominal distention, jaundice. Plain abdominal X-ray study combined with upper gastrointestinal series was the most commonly used diagnostic method. The operative procedures were performed by same pediatric surgeon utilizing Ladd's procedure in 26, duodenoduodenostomy in 8, duodenojejunostomy in 4, excision of wind-sock membrane in 1. A total of 15 associated congenital anomalies were found in 9 patients. Postoperative complications occurred in 13 (33.3%). Overall mortality was 2.6%(1/39). Bilious vomiting and plain abdominal radiologic study were most useful for the diagnosis of congenital duodenal obstruction. Early diagnosis and operative intervention were important to prevent complications such as sepsis and peritonitis.

PURPOSE: To analyze hemodynamic parameters of electrical bioimpedance on increased blood pressure induced by pneumoperitoneum and compare hemodynamic effects of propofol and isoflurane during laparoscopic cholecystectomy. METHODS: Systemic vascular resistance index(SVRI), index of contractility(IC), end diastolic index(EDI), mean arterial pressure(MAP) and heart rate(HR) were measured after anesthetic induction, 5, 10, 15 and 30 minutes after CO2 insufflation and after CO2 removal. RESULTS: In isoflurane group, MAP, IC, SVRI were increased but EDI was decreased after induction of pneumoperitoneum. In propofol group, MAP, SVRI were increased but IC was decreased after induction of pneumoperitoneum. HR was not changed during operartion. CONCLUSION: After induction of pneumoperitoneum, MAP is increased by increased IC and SVRI in isoflurane. In case of propofol, the MAP is increased by increased SVRI. It seems that increased transmural pressure of lymphatics and splanchnic vasculatures rather than sympathetic stimulation increases SVRI after pneumoperitoneum.

Tooth is the most important element in esthetic consideration on facial area. Tooth alignment which is in harmony with gingiva, lips, and face is also key element. The purpose of this study was to give a clinical discipline for restoration of gingival contour, which contains a ratio of maxillary 6 anterior teeth, research for gingival contour etc., in case of rehabilitation of maxillary anterior teeth. 300 Dankook university dental school students ,who is their twenties and free from periodontitis, participate in this study. The result was from each 70 males and females who had normal occlusion and tooth alignment. Length, width and length/width ratio of maxillary 6 anterior teeth were 0.74-0.81 in male, 0.81-0.84 in female. There was significant difference between male and female. The most deepest position of gingiva in maxillary central incisor and canine was located in distal part of teeth and maxillary lateral incisor was middle portion. In maxillary central incisors, gingival line of the most deepest point appeared significant difference between male and female (p<0.01) whereas there was no difference in lateral incisors and canines. Distance between interdental papilla apex and the most deepest portion appeared significant difference beween male and female. Distance of the deepest positon of gingiva is statistically significant except maxillary central incisors and lateral incisors. Standard deviation and mean of the width of labio-lingual were measured in cervical area and there was a significant difference both male and female.(p<0.01) From this result, we could get the mean of maxillary anterior gingival line and these results have great value in clinical guidance in studying maxillary anterior teeth.

Several effective treatment methods and materials have been developed for the treatment of furcation involvement. Currently, the combination of guided tissue regeneration (GTR) and bone grafts is the most commonly prescribed method of treating furcation involved defects. But because these cases often present with poor accessibility, placement of the membrane may be difficult and consequently, clinically impractical. In this study, the alveolar bone healing patterns of adult beagle dogs presenting with alveolar bone destruction treated by one of two methods - treatment using solely bone aIlografts (BBP(R)), or treatment using bone allografts (BBP(R)) stabilized by a fibrin adhesive - were comp ared. The effects of the fibrin adhesive on the initial stabilization of the newly formed bone, subsequent regeneration of bone, and the feasibility of the clinical application of the fibrin adhesive were analyzed. The results of the study were as follows: 1. Clinical signs of inflammation at the 4-8 week interval were not observed: but signs of mild inflammation were histologically observed at the 4-week interval. 2. Allografts stabilized by fibrin adhesive showed good bone formation, whereas defects treated with only the allograft material showed incomplete alveolar bone regeneration. 3. Allografts stabilized by fibrin adhesive showed a decrease in the amount old bone with a concurrent increase in the formation of new lamellar bone four weeks post-op, whereas defects treated with only the allograft material showed no new lamellar bone formation at the same interval. 4. In detects treated with only the allograft material, the defective area was filled with connective tissue 8- weeks post-op, whereas fibrin adhesive stabilized allografts showed viable connections between the original bone and the newly formed bone, in addition to neovascularization 8-weeks post-op. The results of this study show that concurrent use of fibrin adhesive materials can stabilize the allograft material and aid in new bone formation Although the stability of fibrin adhesives fall short of the results achievable by GTR membranes, in cases presenting with poor accessibility that contraindicate the use of membranes, fibrin adhesive materials provide a viable and effective alternative to graft stabilization and new bone formation.

The present study evaluated the effects of guided tissue regeneration using xenograft material(deproteinated bovine bone powder), with and without Calcium sulfate membrane in beagle dogs. Contralateral fenestration defects (6 x 4 mm) were created 4 mm apical to the buccal alveolar crest of maxillary premolar teeth in 5 beagle dogs. Deproteinated bovine bone powders were implanted into fenestration defect and one randomly covered Calcium sulfate membrane (experimental group). Calcium sulfate membrane was used to provide GTR. Tissue blocks including defects with soft tissues which were harvested following four & eight weeks healing interval, prepared for histo-phathologic analysis. The results of this study were as follows. 1. In control group, at 4 weeks after surgery, new bony trabecular contacted with interstitial tissue and osteocytes like cell were arranged in new bony trabecule. Bony lamellation was not observed. 2. In control gruop, at 8 weeks after surgery, scar-like interstitial tissue was filled defect and bony trabecule form lamellation. New bony trabecular was contacted with interstitial tissue but defect was not filled yet. 3. In experimental group, at 4 weeks after surgery, new bony trabecular partially recovered around damaged bone. But new bony trabecule was observed as irregularity and lower density. 4. In experimental group, at 8 weeks after surgery, lamella bone trabecular developed around bone cavity and damaged tissue was replaced with dense interstitial tissue. In conclusion, new bone formation regenerated more in experimental than control groups and there was seen observe more regular bony trabecular in experimental than control groups at 4 weeks after surgery. In control group, at 8 weeks after surgery, the defects was filled with scar-like interstitial tissue but, in experimental group, the defects was connected with new bone. Therefore xenograft material had osteoconduction but could not fill the defects. We thought that the effective regeneration of periodontal tissue, could be achieved using GTR with Calcium sulfate membrane.

Recent studies have demonstrated that the patients with psoriasis have various immune alternation in both humoral and cellular immunities. However the results of these are still controversial. These facts promoted us to analyze the immune cells (T cell, T subsets and B cell) by rosette method for these cells in peripheral blood of 15 patients with psoriasis. And we also analyzed the effects of photo- chemotherapy(PUVA) on these cells. The results were summerized as follows; 1. The mean values of T cell, T, T, cell and B cell in peripheral blood of the- patients with psoriasis before PUVA therapy were 56. 2+-5.7%, 35.1+-6.9%, 5. 5+l.4%, 11.6+4. 0% respectively, These results of immune cells showed signi- ficantly lower mean values when these were compaired with the mean values. of nomnal control group(T cell; 65. 2+-2.9%, TM cell; 45.8+-3.2%, T cell; 7.3+ 1.3% B cell; 16.2+2.4%), respectively (T cell, Tm Tg, p<0.01, B cell; p<0.05). 2.
