We have established an enzyme-linked immunosorbent assay(EL1SA) using enzyme labeled protein G(Protein G-ELISA) to detect Sendai virus-specific antibodies in laboratory animals. Best results were obtained at fl 6.0 of diluent and at 1 to 10 dilution of sera. Antigen concen-tration for solid phase matrix was 5μg /㎖ and the conjugate of horseradish peroxidase (HRP) and prqtein G was used at 1 to 100 dilution. We, also, investigated the sensitivity and speci-ficity of protein G and protein A. Protein C showed relatively high O. D. values than protein A in general. Furthermore, only Protein G-ELISA could detect the Sendai virus specific anti-bodies in rat. though both methods were effective in other species, mouse and guinea pig. No siginificant nonspecific reation was observed at our experimental conditions in both methods.

This study was to examine the effects of the characteristics of exercises on the body composition and the bone mineral density. The subjects were consisted of female athletes and female general students. The numbers of each sample group were 10 long distance athletes, 10 long distance swimming athletes, and 10 general students as a control group. All subjects were measured in their body compositions and bone mineral densities using DEXA method. The results of this study were a s follows; 1. The body fat ratio of the control group was higher than other two experimental groups of female long distance participants and female swimmers, however, the significance was not found. 2. The lean body mass of the swimming athletes group was higher than the other groups of long distance participants and the general students. 3. The bone mineral densities of the general students were higher than the other two groups of long distance athletes and the swimmers. Among the comparison of each part of bone mineral densities, the swimmers' group showed the higher rate compared to the other two groups of long distance athletes and general students, however, no significance was identified. 4. In the comparison of lumber bone mineral density, the general college students showed a significant difference compared to the other two groups of athletes. The mean value of general college students' lumbar bone mineral densities value was higher than the other two groups of athletes. 5. The total body mineral content of the general women's was higher than the other two groups of the athletes, however, no significance was found. 6. In the comparisons of the lumbar none mineral content, the college students showed the highest values among the three groups in which the swimmers' group showed the higher mean value than the long distance athletes group, however, no significances were found. In the results of this study, exercises can be effective on maintaining the bone mineral density normal, however, an excessive training seemed to cause dysmenorrhea for young female athletes. Therefore, low strength exercise combined with the appropriate nutrition provisions could be recommended rather than excessive training.

This study was designed to distinguish by the characteristic difference and the degree of symptoms such as fatigue, pain, coping to pain, and efficacy on pain, and to offer descriptive data for nursing intervention for improving coping ability to pain along each characteristics of disease in chronic arthritis and systemic lupus erythematosus. The subjects were 135 outpatients in the hospital for rheumatic disease in H-University, Seoul. The data were collected by structural questionnaire, from April 29 to June 29, 1999. The results were that the fatigue score was high in the OA patients while the RA patients and SLE patients experienced middle range of fatigue score, but which was not statistically different. Although the RA patients felt higher pain than other diseases, they have well coped with their pain than the others. In efficacy on pain the SLE patients had higher score than others but all of the disease showed lower score. No statistically significant difference among the three croup was recorded in efficacy on pain. Therefore, pain management in the RA patients was primary nursing intervention because they felt severe pain and have well coped with pain while they had lower pain efficacy score than the others. It is also important that fatigue management and coping strategies on pain for the OA patients and SLE patients are specially supportive in the nursing intervention.

The aim of this study was to estimate the minimum irradiation time for dental composites using a dynamic mechanical analyzer (DMA) and FT-IR. Six commercially available dental composites with A3 shade were tested: Heliomolar RO (Vivadent, Liechtenstein), Charisma (Kulzer, Germany), Herculite XRV Enamel (Kerr, USA), Aelitefil (Bisco, USA), Z100 (3M, USA), and Z250 (3M, USA). Storage modulus was measured by using DMA (StressTech Rheometer, Rheologica Instrument, Sweden) with fast oscillation mode (1 Hz). After disk-type (4 ㎜ ?1 ㎜) samples were irradiated with 500 mW/cm2 for 1, 2, 3, 4, 5, 10, 15, 20, and 30 s, storage modulus was recorded continuously for 60 min. Degree of conversion was also measured using FT-IR spectroscopy (FTS-165, Biorad Win-IR, Perkin-Elmer, USA) at 60 min after irradiation with same curing condition as DMA test. Sample irradiated with 500 mW/cm2 for 120 s was used as a control. The average of results for five specimens was compared using Tukey multiple comparison test (p=0.05) and the minimum irradiation time of composites was determined. The minimum irradiation time to get adequate polymerization was different depending on the dental composites. Both Z100 and Z250 require short irradiation times (5 s) and Charisma requires long irradiation time (15 s).

Corrosion of dental alloys in the oral cavity can affect the mechanical, esthetic properties and efficiency of metallic restorations, and has great influence upon the local and systemic health of patients. The purpose of this study was to clarify the corrosion behavior of various dental alloys, and to measure the galvanic currents between dissimilar alloys. Fifty-eight kinds of dental casting alloys such as twenty-nine high gold alloys, ten low gold alloys, fourteen silver-palladium alloys, five base metal alloys, and twenty kinds of ceramic alloys such as seventeen noble metal alloys, three base metal alloys, were used as the experimental alloys. Modified Fusayama's artificial saliva titrated to pH 6.7 with phosphoric acid was used as an electrolyte. The specimens were immersed in the modified artificial saliva of 37℃. The rest potentials, anodic polarization curves, corrosion potentials, and galvanic currents were measured by using the potentiostat / galvanostat and zero shunt ammeter. From the experiment, the following results were obtained : 1) The gold based alloys showed the high rest potentials and the low current densities within experimental potential range. 2) The rest potentials and the current densities of the palladium-based alloys were influenced by the content of platinum, palladium, and silver. 3) In the nickel-chromium base alloys, the formations of passivation film were influenced by chromium content. The copper-aluminum alloy showed very high current density which was more than 150 mV . 4) The corrosion potentials of ceramic alloys were lower than those of dental casting alloys, but the trend of anodic polarizations were generally similar to the other alloys. 5) The amount of galvanic current and the polarity in the bimetallic galvanic cell could not be predicted considering only the alloy composition. The galvanic current decreased while the measuring time passed, but flew continuously.
