STATEMENT OF PROBLEM: For a long time, many of denture base acrylic resins have been used for edentulous and partial edentulous patients because of easy manipulation and good mechanical properties, but its esthetic aspect has not been commented enough. Denture base acrylic resins also has caused esthetic problems due to discoloration or staining as in esthetic restoration. Many researches and reports have treated the problems and accomplished esthetic improvement. But these researches and reports dealt with general food colors or beverages, not with fermented foods. PURPOSE: This study is designed to assess what fermented foods, such as soy sauce, gochujang, and toenjang that many of Koreans have taken in, influence on the color and hardness variation of denture base acrylic resins. MATERIALS AND METHODS: For the procedure, twelve disks per 4 denture base acrylic resins were fabricated with a thickness of 2mm and 16mm in diameter. Each seven specimen were measured for discoloration with spectrophotometer, while the others, five specimen, for surface hardness change with Barcol hardness tester, over time. Each 12 specimen were immersed into the 4 beakers of fermented foods(soy sauces, gochujangs, toenjangs, deionized water), and L*, a*, and b* values were measured for the color difference(_E*), on the 1st, 7th, and 28th day with spectrophotometer, with the measurement of surface hardness change. Each data observed was processed statistically. RESULTS: The findings are as follows; Discoloration 1. All of denture base resins was not influenced by the kind of fermented foods, except for QC20. 2. Soy sauce and red pepper paste caused more change for denture base resins than deionized water and soy bean paste, except for Perform. 3. Most significant change was shown in Lucitone199., whereas Perform. results in the least change for all immersed solution, with no statistical significance. Hardness change 1. Barcol hardness values in deposited specimens have been changed low degree, but with significant statistical change according to the kind of food and duration. 2. Lucitone199. has significantly lower Barcol hardness value than others do. CONCLUSION: Based on the above results, it suggests that the habitual intake of fermented foods is not helpful for the color stability of denture base acrylic resins because Soy sauce and red pepper paste mainly caused discoloration and surface hardness change. Particularly Lucitone199. shows specific discoloration and low surface hardness values. Therefore, it is recommended giving caution patients with denture of Lucitone199. especially against the habitual intake of fermented foods like soy sauce and red pepper paste.

BACKGROUND: The propose of this study was to identify the level of medical technologists' perception of and compliance with hospital infection control guidelines. METHODS: A questionnaire survey was conducted for 65 medical technologists working at three university hospitals in Seoul and Kyunggi areas. The questionnaire was composed of 34 questions on the general characteristics (14 items) of individual responders and about infection control guidelines (20 items). Their response was marked on the basis of 5 points for each question. RESULTS: The mean scores of the perception of and compliance with the infection control guidelines were 4.62+/-0.34 and 3.85+/-0.42, respectively. The female technologists scored significantly higher than did the male counterparts in the participation level of the infection control guidelines (P<0.05). The medical technologists who had participated in an infection control educational program were more likely than those who had not to show a higher compliance level on the infection control guidelines (P<0.05). CONCLUSION: The study demonstrated that the development of infection control educational programs for medical technologists and a supportive policy of the hospital administration should contribute to the prevention of nosocomial infections.

Nephrogenic diabetes insipidus (NDI) can cause nonobstructive hydronephrosis. Congenital NDI (CNDI) is caused by a genetic mutation. This case report presents a 12-year-old girl who was incidentally diagnosed with nonobstructive hydronephrosis due to NDI caused by AQP2 gene mutation after being evaluated for microscopic hematuria found on routine health examination at school. The patient's medical and family history was unremarkable, and she complained of nocturia only at the time of the clinic visit. Bilateral hydronephrosis on abdominal ultrasonography prompted a water deprivation test, leading to diagnosis of NDI. Genetic study confirmed p.Asn (AAC)123Ser (AGC) in exon 2 of the AQP2 gene. Polyuria and hydronephrosis improved following arginine-vasopressin therapy. CNDI responsive to treatment should be considered as a possible cause of nonobstructive hydroureter.

In a study of primary brain tumors 104 cases having satisfactory clinical, operative and histological proofswere analyzed by computerized tomography at Presbyterian Medical Center from May, 1982 to April, 1985. The resultswere as follows: 1. The male to female ratio of primary brain tumor was 54:46. 2.The 2nd decade group (26%) wasthe most prevalent age group, followed by the 5th decade(16.3%), 1st decade(14.4%), 3rd decade(12.5%), 4thdecade(11.5%), 6th decade(10.6%), 7th decade(8.7%) in that order. 3. The incidence of primary brain tumors was found to be: glioma 64 cases(61.6%) (among the GM, the most frequent 17 cases(16.3%), followed by meningioma 12cases (11.5%), pituitary adenoma 10 cases (9.6%), craniopharyngioma 6 cases(5.8%), pinealoma and germinoma 3cases(2.9%) respectively, and dermoid cyst 2 cases(1.9%) in that order. 4. The locations of the primary braintumors were as follows: cb. hemisphere(49%) of these 24.5% in parietal region, 11.9% in temporal region, 9.7% infrontal region, 3.0% in occipital region: Juxtasella area(16.3%), cerebellar hemisphere(8.7%), Parapineal andintraventricle(7.7%) respectively, cerebello-pontine angle area(5.8%), vermis and 4th ventricular region(4.8%). 5.There were no remarkable differences in the findings of pre-and post-contast CT scanning of primary brain tumorscompared with others.
