To evaluate the efficacy of transdermal scopolamine patch in reducing nausea and vomiting associated with general anesthesia, we studied 60 healthy women undergoing major gynecologic surgery. The patients were divided into 2 groups. Each group was composed of 30 patients. Group I; not applied a transdermal scopolamine patch. Group II: applied one transdermal scopolamine patch on the skin behind her ear at the night before surgery. Anesthesia was induced by thiopental sodium(5 mg/kg) and succinylcholine(1.5 mg/kg) and maintained with fentanyl(3-6 ug/kg), enflurane(0.5-1.5 vol%) and nitrous oxide(50 vo1%) in oxygen. A comparison with Group I and Group II indicated that the transdermal scopolamine patch reduced the incidence of postoperative nausea or vomiting associated with general anesthesia significantly(Group I; 36.67%, Group II; 13.33%, p<0.05).

PURPOSE: The purpose of this study was to evaluate the surface characteristics and response of osteoblast-like cell at SLA surface treated with NaOH. MATERIALS AND METHODS: Three kinds of specimens were fabricated for the experiment groups. Control group was a machined surface, SLA group was a conventionally SLA treated surface, and SLA/NaOH gorup was SLA surface treated with NaOH. To evaluate the surface characteristics, the surface elemental composition (XPS), surface roughness and surface contact angle were evaluated in each group. And the cytotoxicity, cell adhesion, cell proliferation and ATP activity of osteoblast-like cells (MG-63 cells) were compared in each group for evaluatation of the cell responses. Statistical comparisons between groups were carried out via one-way ANOVA using the SPSS software (SPSS Inc., Chicago, USA), and then performed multiple comparisons. The differences were considered statistically significant at P<.05. RESULTS: SLA surface treated with NaOH (SLA / NaOH group) was changed to hydrophilic surface. All groups did not show the cytotoxicity to the MG-63. In cell adhesion studies, SLA / NaOH group showed the higher degree of adhesion than anothers (P<.05), Up to 7 days of incubation, the proliferation was showed the increasing tendency in all groups but SLA / NaOH group showed the highest cell proliferation between the three groups (P<.05). At 7 days of incubation, there was no difference in ALP activities between the three groups, but at 14 days, SLA / NaOH group showed significant increase in ALP activities (P<.05). CONCLUSION: In this study, SLA surface treated with NaOH promoted cell adhesion, proliferation and differentiation. It means that SLA/NaOH group is possible to promote osseointegration of implants.

Closed mouth impression technique by using bite tray is preferred for single tooth impression taking. However, for implant impression taking, open mouth impression technique by using single arch tray is generally used whether it is for single implant or multiple implant. Closed mouth impression technique by using bite tray can save time and materials. It also decreases the chance of error occurrence when a model is mounted on an articulator. In this case report, we tried to show a satisfying result of fabricating single implant fixed prosthodontics after bite tray impression taking by using two different copings for closed mouth impression.

Purpose: Caring for a vulnerable premature baby is a challenging task, but some mothers experience growth through that process. The purpose of this study was to investigate the factors influencing post-traumatic growth in mothers with premature infants admitted to the neonatal intensive care unit. Methods: A correlational research design was used and 105 mothers of premature infants were recruited from an online community. Data were collected from January 15 to January 25, 2019. Post-traumatic growth was measured using the Korean version of the Posttraumatic Growth Inventory. Data were analyzed using descriptive statistics, the t-test, analysis of variance, the Scheffé test, Pearson correlation coefficients, and hierarchical multiple regression. Results: The final model developed in this study explained 45.5% of post-traumatic growth (F=13.66, p<.001). Resilience (β=.54, p<.001) was the strongest predictor of post-traumatic growth, followed by the age of the mother when giving birth (β=.17, p=.028) and current employment status (β=.17, p=.049). Conclusion For mother with premature infants to grow psychologically after their experience, it may be needed to support them to develop and strengthen their resilience through either education or their own support network.

To investigate the effect of smoking on the hearing threshold, l,887 adult male workers who visited health care center during the period l January 1996 - 31 July 1997 were selected. Air-conduction hearing threshold level, diastolic blood pressure(DBP), total cholesterol, fasting blood sugar(FBS), hematocrit and obesity, were measured. The data on age, occupation, and smoking were collected. Air-conduction hearing threshold in smoker was significantly higher than non-smoker in categories of 250, 500, 1000 and 4000 Hz(p<0.05). Mean values of PTA-low, PTA-mid, and PTA-high in smoker were also significantly higher than non-smoker(p<0.05). In multiple regression analysis, smoking is likely to play a significant role after controlling age, occupation, DBP, FBS, total cholesterol, hematocrit, and obesity,(p<0.05). The hearing threshold was significantly increased with increasing age(p<0.05), the manufacturing worker may have higher hearing threshold(p<0.05). The higher hematocrit and the more obese, the higher hearing threshold(p<0.05). However, DBP, total cholesterol and FBS were not significantly related with hearing threshold level. In conclusion, smoking was significantly related with the hearing threshold level in adult men.
