The purpose of this study was to compare the corrosion characteristics between implant fixture and two types of abutment screw; gold screw, titanium screw. The anodic polarization behavior, the galvanic corrosion behavior, and the crevice corrosion behavior of prepared samples were investigated using potentiostat and scanning electron microscope. The results were as follows : 1. Anodic polarization behavior of samples: The primary passivation potential of implant fixture was -420mV, implant abutment was -560mV, titanium screw was -370mV and gold screw was -230mV. All samples were shown to have a high corrosion potential and good formation of passive film. The critical passive current density of gold screw was higher than of other samples and the sample of gold screw showed a unstable passive film formation at passive region. 2. Galvanic corrosion behavior of samples: Contact current density between implant fixture and titanium screw showed 8.023x 10-5C/cm2. Contact current density between implant fixture and gold screw showed 5.142x 10-5C/cm2. 3. Crevice corrosion behavior of samples : The crevice corrosion resistance of sample using titanium screw was higher than that of sample using gold screw, and a severe corrosion morphologies were observed at the fixture-screw interface by the scanning electron microscope.

DiGeorge syndrome, a developmental defect of the third and fourth pharyngeal pouches, is characterized by aplasia or hypoplasia of the thymus and parathyroid glands and by conotruncal cardiac malformation. This syndrome is usually associated with deletion of long arm in chromosome 22 (22q11-). We experienced a case of partial DiGeorge syndrome in a 2-month-old male who had hospitalized because of recurrent hypocalcemic tetany and tetralogy of Fallot. Immunologic studies revealed the decreased percentage of T lymphocyte and increased percentage of B lymphocyte. Chromosomal study with high resolution banding, showed 46, XY, 22q13 deletion. We report a case of partial Digeorge syndrome with a brief review of literatures.

This study examined the characteristics of people who have preference for complementary medicine and also the psychosocial factors that are related to the selection of complementary medicine. Two-hunred subjects recruited from the community were included in this study. Demographic variables, medical service characteristics, health locus of control, social support, coping style, and personality charateritics such as self-esteem, neuroticism, and hypochondriasis were measured. It turned out that nearly 80% of the subjects had already experienced at least one alternative therapy in the past. However, past expeiece was not significant in predicting future complementary medicine usage. People who were older in age, had more information about complementary medicine, used active-behavioural coping styles, and had internal locus of control were more likely to use complementary medicine in the future. Recommenations for furthur research is indicated.

In order to evaluate the accuracy of endoscopic findings in the diagnosis of gastric can the endoscopic findings of gastric lesion were compared with the macroscopic and pathologic findings of excised identical lesion. 105 operated gastric cancer paitients (advanced cancer 95 cases, early cancer 10 cases) who were diagnosed endoscopically at Pusan National University Hospital from January 1983 to August 1987 were studied. The results were as follows; 1) The accuracy of endoscopic findings were 94.7% in the advanced gastric cancer, and 45.5% in the early gastric cancer. 2) The accuracy of gross findings endoscopic and pathologic in advanced gastric cancer were 50.0% in Borrmann type I, 45.0% in Borrmann type II, 73.2% in Borrmann type III, and 66.7% in Borrmann tyye IV. 3) The accuracy of the endoscopy ia morphologic classification of advanced gastric cancer according to pathologic tumor location were 60.0% in C (upper 1/3), 43.9% in M(middle 1/3),76.3% in A (lower 1/3), 55.6% in the anterior wall, 50.0% in the posterior wall, 66.7% in the greater curavature, and 67.2% in the lesser curvature. 4) The accuracy of endoacopy in morphologic classification of gastric cancer to tumor size ware 54.5% in below 2 cm, 54.5% in from 2.1 cm to 4 cm, 65.4% in from 4.1 cm to 6.0 cm, 80% in from 6.1 cm to 8 cm, 75.0% in above 8.1 cm. 5) The accuracy of endoscopy in the morphologic classification according to the pathologic tumor stage in advanced gastric cancer were 55.6% in TNM stage I, 52.0% in TNM stage II, 65.4% in TNM stage III, and 73,7% in TNM stage IV.

Kallmann's syndrome is characterized by hypogonadotrophic hypogonadism resulting from insufficient release of GnRH and associated with anosmia or hyposmia, which has been related to agenesis of olfactory bulbs. We experienced a case of 17 year-old Kallmann's syndrome woman and a case of successful pregnancy of 29 year-old Kallmann's syndrome woman with hMG and hCG treatment and present two cases with a review of literatures.

With a surge in the population of immunocompromised patients, the incidence of laryngeal fungal infection has also been increased. Infection by aspergillus, which is a kind of mold, or a filamentous fungus, occurs rarely in larynx. Furthermore, most aspergillosis of the upper airway is an extension of the pulmonary or systemic aspergillosis in the immunocompromised host. So, the primary laryngeal aspergillosis that occurrs as an isolated laryngeal infection of aspergillus without other aerodigestive tract extension is very rarely encountered. We present a case of primary laryngeal aspergillosis misconceived as a vocal cord cyst in a 24-year-old female who had no past history of immune deficiency, voice abuse or steroid use.

Brown tumors are erosive bony lesions caused by the chronic excessive secretion of parathyroid hormone. Since the introduction of routine calcium measurement, the diagnosis of hyperparathyroidism has usually been made in asymptomatic patients, and as a result, brown tumors are rarely observed as an initial manifestation of hyperparathyroidism. The authors report a case of a 32-year-old woman who presented with right cheek swelling. A CT scan showed erosive bone tumors of the mandible. These lesions were finally diagnosed as brown tumors associated with secondary hyperparathyroidism due to chronic renal failure. Brown tumor as a result of hyperparathyroidism is a relatively rare clinical finding in otorhinolaryngology, thus, the authors illustrate this case with a brief review of the literature.
