DNA found at the scene of a crime is often damaged and degraded to small fragments and remained in low quantity. Therefore, there are some difficulties in forensic STR typing of these DNA samples. In this study, to overcome these limitations as different approach, we applied repairing enzyme to damaged DNA. The efficacy of a repair enzyme system (PreCR Repair Mix) was evaluated by using several types of artificially damaged and naturally damaged DNA. The results showed that autosomal STR amplification produced increased yield in the DNA damaged by UV irradiation, oxidation, or acid/heat, and DNA from dried blood spot and dried saliva spot by treatment of a repair enzyme, but not in DNA extracted from old skeletal remains. In conclusion, a repair enzyme will be efficiently applied to forensic samples which were damaged by UV irradiation, oxidation, and acid/heat.

We report 3 cases of multiple myeloma showing ABO discrepancy with missed reaction in serum typing. They showed markedly decreased immunogolobulin level except for monoclonally increased abnormal immunoglobulin. Their blood group was confirmed by saliva test and addition of anti-globulin reagent. As serum immunoglobulin level is raised, the reactivity in serum typing showed improving tendency and ABO discrepancy appeared when immunoglobulin was markedly decreased.

OBJECTIVES: The purpose of this study was to compare the shade changes in wet and dry conditions of natural teeth using two different intra-oral colorimeters. MATERIALS AND METHODS: Twenty volunteer subjects have no restorations and fillings in the maxillary central incisors were involved in this clinical study. The color of tooth was measured by two different instruments that were a Shade Scan(TM) System and a VITA Easyshade(R), Five times consecutive measurements were done for each subject with both instruments. Groups of measurement are an initial wet condition as control, dry in 5 minutes, 15 seconds after re-wetting with saliva, re-wetting after 5minutes and re-wetting after 30 minutes. Using ShadeScan System(TM), tooth image was captured and converted to the mapping image of Vitapan 3D master. Three main shades were chosen from each subject and calculated the area in Global Lab Image software. Data were analyzed using paired T-Test and Wilcoxon Signed Ranked Test. Using VITA Easyshade(R), color differences(deltaE) between measurements were analyzed with one sample T-test. RESULTS: Using ShadeScan System(TM), there were significant differences between control group and dry(P=.023), dry and re-wetting 15 seconds, 5 minutes, 30 minutes as well(P=.021, P=.017, P=.030) in comparison of primary shade. However, comparing three main shades, there was no significant difference between control and dry(P=.105). Using VITA Easyshade(R), color differences(deltaE) between control and dry, dry and re-wetting 30 minutes were statistically different(P=.002, P=.022). CONCLUSION: Primary shade could be changed in dry and wetting procedure in time, however there was no significant shade changes in overall.

Korean Journal of Orthodontics 1991;21(3):563-580
The purpose of this study was to investigate and compare the biomechanical properties of orthodontic rubber elastic materials. Latex bands, nylon-covered elastic threads and polyurethane-based elastic modules, delivering 205 +/- 10 grams force at 30mm stretching state were selected and stored separately in 3 environments-air (22+/-3degreesC), distilled water (37+/-1degreesC), or natural saliva (37+/-1degreesC). And, the amount of remaining force and permanent elongation of each sample were measured on Instron at interval of 1 hour, 6 hours, 12 hours, 24 hours, 1 week, and 2 weeks. So the data derived were analyzed statistically. The results were as follows: 1. Force decay and permanent elongation of all materials increased with time lapsed; elastic module, latex band and nylon-covered elastic thread in that order of the amount of force decay; elastic module, elastic thread, latex band in that order of the amount of permanent elongation. 2. Among environmental conditions, force decay and permanent elongation in natural saliva, most increased, and those in air, least increased. 3. There was a negative correlation between force decay and permanent elongation. 4. Force decay and permanent elongation were most affected by the material itself, time and environments in that order. 5. After 24 hours in saliva, the percentage of remaining force in elastic module was 51.9% (107.37grams); in latex band, 83.2%(172.62grams); in elastic thread, 85.0%(179.25grams). After 2 weeks in saliva, the percentage of remaining force in elastic module was 42.9%(88.75grams); in latex band, 74.5%(154.50grams); in elastic thread, 77.6%(163.75grams).

10.Effects of Saliva Contamination on Shear Bond Strength with Conventional, Moisture Insensitive, and Self-Etching Primers
Journal of Korean Academy of Pediatric Dentistry 2019;46(1):21-28
The aim of this study was to compare the shear bond strengths of orthodontic bracket with Conventional primer (CP), Moisture insensitive primer (MIP), and Self-etching primer (SEP). In addition, the effect and the timing of saliva contamination on shear bond strength was evaluated.A total of 135 bovine mandibular incisors were used in the study and divided into 3 groups. Group I, II and III were used CP, MIP, SEP, respectively. Each group was then divided into three subgroups: the group without saliva contamination, the group with primer application after saliva contamination, and the group with saliva contamination after primer application. After the primer application, the metal bracket for the lower incisor was attached and the shear bond strength was measured.The mean shear bond strengths was highest with CP and lowest with SEP in dry condition. However, CP showed a significant decrease in shear bond strength in the presence of saliva contamination. MIP and SEP showed no significant decrease in shear bond strength with saliva contamination.
