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.

Infantile hypertrophic pyloric stensosis (IHPS), which occurs three of 1,000 live births, is a major cause of nonbilious vomiting of early infancy, but its etiology and pathogenesis are still obscure. The operation of pyloromyotomy as described by Ramstedt in 1912 remains the standard of care for the treatment of IHPS. From January 1990 to July 1997, 64 infants with IHPS were reviewed at department of Pediatric Sursery, Yeungnam University Hospital. The ratio of male to female was 7:1, and the most prevalent age group was between 2 weeks and 8 weeks (81.2%). There were 37 (57.8%) first born babies among total 64 infants. The body weight percentile at admission was lower than 50 percentile in all 64 cases. Onset of symptoms was predominantly between 2week and 4weeks in 23 cases (35.9%). All had a history of nonbilious vomting, generally projectile in nature. In the measured serum electrolytes, hypokalemia was noted in 14 cases (21.9%), hypochloremia was observed in 26 cases (40.6%). In the preoperative ultrasonography, the average muscle thickness, diameter, and length of the pylorus were 6.3mm, 12.3mm, and 17.8mm, respectively. A total of thirteen associated anomalies were noted in twelve patients. All 64 cases were treated with Fredet-Ramstedt pyloromyotomy. There were postoperative complications of wound infection in 3 cases. Intermittent nonprojectile vomiting was presented in 13 cases (20.3%) after operation, but one of them was relieved in 13 days and the rest were relieved within one week by adjustment of oral intake.

Several indices have been developed that use bleeding and color changes as indicators of early gingival pathology. In the presence of gingivitis, vascular proliferation and reduction of keratinization owing to increase redness in gingiva. Descriptions of healthy gingiva are numerous, ranging from pale pink and coral pink to deep red and violet. This terms are not objective. Because of perception of color depends on a lot of factors such as light source, object, observer and so on. It is difficult to make an objective expression. Therefore the using of mechanical equipment is recommended to exclude these variables and observer's vias. The purpose of this study was to evaluate gingival color change after scaling & subgingival root planing. The other purpose of this study was to research the correlation of pocket depth, P.B.I. score and gingival color change. After photo-taking and storaging the image of gingival color into a computer, color change was examine with an image analysis program. Results were as follow; 1. Color of healed gingiva after scaling & subgingival root planing was significantly differ from color of inflamed gingiva(p<0.01). 2. Color of healed gingiva after scaling was similar to color of healed gingiva after subgingival root planing(p<0.05). 3. There was statistically significant correlation between color change of red component and pocket depth after scaling & subgingival root planing(p<0.01) 4. There was no correlation between color change of green, blue component and pocket depth after scaling & subgingival root planing(p<0.01) 5. There was statistically significant correlation between between color change of red component and P.B.I. score after scaling & subgingival root planing(p<0.01). 6. There was no correlation between color changes of green, blue component and P.B.I. score after scaling & subgingival root planing(p<0.01) 7. Increase of pocket depth and P.B.I. score were significantly correlated to the amount of color change(p<0.01). 8. P.B.I. score had a higher correlation with color change than pocket depth(p<0.01).

Acute normovolemic hemodilution is widely used to conserve blood and to minimize the need for homologous blood transfusion during operation. To evaluate the effects of aeute isovolemic hemodilution on hemodynamics and oxygen transport, pulmonary artery catheter and radial artery catheter were introduced in 8 patients in whom maxillofacial or Wertheim's operation were performed. Blood(estimated from allowable blood loss) was withdrawn from radial artery, and simultaneously replaced by intravenous administration of 5% plasmanate and Hartmann solution. Acute isovolemic hemodilution decreased the hematocrit level from 33.2+/-3.7% to 29.6+/-2.9%. Cardiac output increased significantly, which was associated with decreased systemic vaacular resistance. Oxygen transport and oxygen consumption increased despite a decrease in oxygen carrying capacity. Heart rate, mean arterial perssure, mean pulmonary arterial pressure, central venous pressure, and pulmonary capillary wedge pressure did not change significantly during hemodilution. The results indicate that blood perfusion and oxygenation to tissue were well maintained in the hemodilution of the magnitude used in this study. Therfore it could be concluded that acute isovolemic hemodilution is a safe and relatively simple method of conserving blood and minimizing homologous blood transfusion.

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.
