BACKGROUND: The prevention of preterm deliveries still remains a major problem in ob-stetrics. The cause of preterm labor is poorly understood. Our purpose was to determine the risk factors for preterm labor associated with specific clinical and environmental factors. METHODS: Using a case-control design, 54 women with preterm labor and 134 controls with term labor, who were admitted to the department of Obstetrics and Gynecology, Dan- kook University Hospital from January, 1996 to August, 1996. The study groups were inte- rviewed and their medical records were reviewed. RESULTS: 1. There were no significant differences of maternal age, maternal weight at 20 weeks of gestation and maternal weight gain at the time of delivery. 2. There were no significant differences between housewives and working women. But the physical workload of the preterm labor group was significantly higher than the control group ( 16.0% vs. 4.0% ). 3. There were no significant differences in the smoking habit of mother or her husba- nd. The passive smoking of the preterm labor group was significantly higher than the con- trol group ( 43.8% vs. 26.8% ). 4. In vaginal bleeding at pregnancy, the preterm labor group was significantly higher than the control group ( 15.7% vs. 2.3% ). Especially, the third trimester vaginal bleeding of the preterm labor group was significantly higher than the control group. 5. There were no significant differences in the number of previous fullterm deliveries, previous abortions, and living children between two groups. The experience of the previous preterm deliveries of the preterm group was significantly higher than the control group ( 11. 5% vs. 0.8% ). 6. There were no significant differences of medications, consumption of alcohol, coffee, tea, green-tea, cola and nutritional beverages, the experiences of coitus, defecation numbers and accidents during pregnancy between two groups. 7. There were no significant differences in the plasma concentrations of hemoglobin, hematocrit, white blood cells, and in the blood pressure, and the body temperature between two groups. CONCLUSION: The risk factors of preterm labor were severe physical workload, vaginal bleeding at pregnancy, especially, the third trimester vaginal bleeding, and the experience of previous preterm deliveries.

A 29-year-old Korean woman visited the Department of Surgery in MizMedi Hospital with a palpable itching mass on the right breast that had existed for the past 7 months. She had no history to eat either frogs or snakes, but had the history of drinking impure water. Sonography revealed a serpiginous hypoechoic tubular structure associated with partial fat necrosis in breast parenchymal layer and subcutaneous fat layer. It also revealed oval cystic lesions. At operation, an ivory white opaque ribbon-like worm that measured 16.5 cm in length and 0.5 cm in width was extracted. Anti-sparganum specific serum IgG level in the patient's serum (absorbance = 0.71), measured by ELISA, was found to be significantly higher than those of normal controls (cut off point = 0.21). Sonography and ELISA appear to be helpful to diagnose sparganosis. Breast sparganosis is rarely found throughout the world.

PURPOSE: This study was conducted to examine the effects of an individualized cardiac rehabilitation education program on knowledge about coronary artery disease (CAD), compliance of sick role and vascular health status in patients with percutaneous coronary intervention (PCI). METHODS: Quasi-experimental design-based nonequivalent control group pretest-posttest design was employed. Using convenience sampling, data were collected from 60 patients who underwent PCI at S Hospital in S City from September 2014 to February 2015. For examining the effects of an individualized cardiac rehabilitation education program, knowledge about CAD, compliance of sick role and vascular health status were measured. RESULTS: The experimental group showed statistically significant differences in knowledge about CAD (t=24.21, p<.001), compliance with sick role (t=20.81, p<.001) and vascular health status (t=15.07, p<.001) compared to the control group. CONCLUSION: The individualized cardiac rehabilitation education program is effective in improving knowledge about CAD, compliance of sick role and vascular health status in patients who underwent PCI. Based on the findings of this study, nursing intervention programs focusing on individualized approach will be useful for patients undergoing PCI.

PURPOSE: The purpose of this study was to identify influencing factors on health behavior adherence in middle and old aged men who underwent percutaneous coronary intervention. METHODS: With a convenience sampling, data were collected from 140 middle and old aged men who underwent percutaneous coronary intervention at two general hospitals. A structured questionnaire was used to measure husband-wife harmony, self-efficacy, and behavior adherence. Data were analyzed by descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression. RESULTS: Health behavior adherence was significantly correlated with husband-wife harmony (r=.59, p<.001) and self-efficacy (r=.54, p<.001). There was also a significant correlation between husband-wife harmony and self-efficacy (r=.48, p<.001). Overall, approximately 43.7% of the variability in health behavior adherence was explained by these two variables in this study (F=54.85, p<.001). CONCLUSION The findings suggest that husband-wife harmony and self-efficacy could be important factors affecting health behavior adherence in middle aged men who underwent percutaneous coronary intervention. Therefore, nursing interventions for them should focus on increasing husband-wife harmony and self-efficacy.

PURPOSE: The purpose of this study was to identify whether self-directed fundamental nursing practice using a smart phone affected self-efficacy, practice satisfaction, and skill competency of nursing students. METHODS: This was a nonequivalent control group pretest-posttest quasi-experimental design. The participants were 40 children in the experimental group and 40 in the control group. In experimental group, self-directed fundamental nursing practice using a smart phone was given to nursing students. Data for this study was collected from 25 March 2015 to 10 April 2015. The data were analyzed using SAS 21.0. RESULTS: In self-efficacy and skill competency, there were no statistically significant differences between the experimental group and control group. In practice satisfaction, there were statistically significant differences between the experimental group and the control group. CONCLUSION: The results indicate that self-directed fundamental nursing practice using smartphone video is effective in practice satisfaction. Therefore, this intervention can be utilized in nursing practice education as an effective educational device.

BACKGROUND: The purpose of this study was to evaluate the efficacy of suction drain use following arthroscopic rotator cuff repair by comparing early pain score and range of motion (ROM) between groups with and without suction drains. METHODS: The study included 153 patients with rotator cuff tears who underwent arthroscopic repairs at our clinic from April 2014 to March 2015. Following surgery, a suction drain was used in 85 patients (group D) and not used in 68 patients (group ND). There was no statistical difference between the groups in terms of age, gender, or total operation time. The clinical outcome with regard to pain (assessed by pain scores and analgesic requests) and passive ROM was assessed preoperatively and postoperatively. RESULTS: Immediate postoperative analgesic requirement was significantly higher in group D (p=0.001), although there was no difference in pain outcomes between the groups during the 3-month follow-up period. A statistically significant difference in passive ROM was observed at the postoperative 2- and 6-week follow-ups (p=0.036, 0.035, and 0.034 in forward elevation (FE), external rotation at the side (ER) and 90 ER at weeks 2, respectively; 0.045 and 0.009 in FE and ER at weeks 6, respectively); however no significant difference was observed at the end of 3 months. During the study period, no complication was reported in either group. CONCLUSIONS: Use of suction drains after arthroscopic rotator cuff repair provided little benefit in terms of ROM or pain in the early postoperative period (up to 3 months).

BACKGROUND: Retinoids exert a wide range of effects on cell growth and development and have important effects on keratinocytes differentiation in vvc and in vitro. Besides the effects on epithelial differeotiation, modulation of cellular and amoral responses of lymphocytes, changes in natural killer and T-killer cell activities and riodulation of antigen presenting properties were shown by retionds. OBJECTIVE: We studied to investigate the immunologic role of etinoids. METHODS: With foreskin. the effects of 13-cis retinoic acid and etretinate on interferony induced HLA-DR and ICAM-1 expression of kratinocytes were!ev luated. RESULTS: 1. When keratinocytes were grown in low calcium media, priliferation was inhibited only with 8 x 10 M of 13-cis retinoic acid. 8 x 10 , 8 x 10 M of 13-cis retinoic acid and 8 x 10 , 8 x 10, 8 x 10 M of etretinate had no effect on keratinocytes roiferation. When cultured in 0.15 mM calcium media or 1.0 mM calcium media, 13-cis retino acid and etretinate had no effection keratinocytes proliferation. 2. Keratinocytes HLA-DR expression was decreased with 8 x 10 , 8 x 10 M of 13-cis retinoic acid in 0.15 mM carcium media and 8 x 10 , 8 x 10 M of 13-cis retinoic acid in 1.0 mM calcium media. Etretinate had no effect on keratinocytes HLA-DR expression. 3. Keratinocytes ICAM- 1 expression was increased with 8 x 10 M of 13-cis retinoic acid in low calcium. media. When cultured on 0.15 mM carcium media, ICAM-1 expression was increased with 8 x 10 M of 13-cis retinoic acid and tetinate. When cultured in 1.0 mM calcium media, ICAM-1 expression was increased with 8 x 10, 8 x 10 , 8 x 10 M of 13-cis retinoic acid and 8 x 10, 8 x 10 , 8 x 10 M of etretinate. CONCLUSION: These results suggest that retiniods have an immunomodulating effect as well as effects on epithelial differentiation. Clarification of the mechanism of increased expression of ICAM-1 and decreased expression of HLA-DR remains to the proved.

The authors investigated the antiproliferative effect and expression of HLA-DR an- tigen by recombinant gamma-interferon (r-IFN-y) on cultured human keratinocytes (KC). The results were as follows, 1. From 10l.J/ml of r-1FN-p exposure, the proliferation of KC decreased in a concentration dependent fashion. But there was little difference of antiproliferative effect above 30U/ml of r-IFN-y exposure. 2. The expression of HLA-DR antigen on KC increased in a concentration and time dependent fashion of r-IFN-p exposure. E3ut t,here was little difference of HLA-DR antigen expression on KC above 30tJ/ml and most of HLA-DR antigen were expressed within 48hr. 3. The opt,imal condition for HLA-DR antigen induction on KC by r-IFN-p was likely t,hat HLA-DR KC was observed at 48hr under the our exposure of 30U/ml of r-IFN p. 4. After 4hr exposure of 30U/ml of r-IFN-p, KC expresed HLA-BR. antigen, reaching a maximum intensity at 3 days. At, 7 days, the loss of HI A-DR KC showed over 90% of maximum intensity.

Human epidermal cells were obtained from suction blisters of 14 healthy individuals, and were cultured for 24-96 hours st a concentration of 1x 10(7)/ml, 5 x 10(6)/ml, 1 x 10(6)/ml, 5 x 10(5)/ml. Cells were also cultured with or without stimulants such as phorbol myristic acetate(PMA), muramyl dipeptide(MDP), and endotoxin. Then, cell-free supernatants of cultured epidermal cells were tested for ETAF by a thymocyte prolifera.tiom assay. The results were as follows : 1, The highest activity of ETAF was produced by fresh epidermal cells(EC) at a concentration of 1 x10(7)ml. Its highest 3H-TdR was 4928+/-2480cpm. The highest activity of ETAF was produced by cultured EC at a concentration of 5 x10(6)/ml. Its highest 3H-TdR was 13983+/-8045 cpm. 2. The highest activity of ETAF was produced by fresh EC with n culture time of 24 hours. Its highest 3H-TdR was 5357+/-3760cpm. The highest activity of ETAF was produced by cultured EC with a culture time of 72 hours. Its highest 3H-TdR was 11905+/-5327cpm. 3. The highest activity of ETAF was produced by both fresh and cultured EC at a titer of 1: 8 dilution of cell-free supernatants. 1ts highest 3H-TdR was 4928 +/-2480cpm in the fresh EC, and 11905+/-5327cpm in the cultured EC. 4. Alhen fresh EC was stimulated with PMA, MDP and endotoxin, higher activity of ETAF was found in the group stimulated with PMA or MDP compared with its control group. But lower activity of ETAF was found in the group stimulated with endotoxin compared with its control group. The 3H-TdR was 6000+/-1936 cpm in the group stimulated with PMA, 6945+/-3182 cpm in the group stimulated with MDP, and 36943+/-36861cpm in the group stimulated with endotoxin.
