PURPOSE: This study was to identify the relations of interpersonal attitude and communication competence of new community health nurses. METHODS: The research design was a correlational study. The data were collected from 136 visiting nurses using a structured questionnaire and analyzed using independent t-test, Pearson's correlation coefficient, and multiple regression with the SPSS/WIN 20.0 program. RESULTS: The type of interpersonal attitude in subjects was I+U+ and the score of communication competence was 3.6. Among 15 sub-dimensions, the highest score was responsiveness and the lowest was assertiveness. There were no significant differences in communication competence by general characteristics. Factors influencing on communication competence in new visiting nurses were interpersonal attitude I+(I am OK) (beta=.34) and I-(I am not OK) (beta=-.28). CONCLUSION: Education program, stressing the self-awareness, is necessary to increase positive interpersonal attitude and communication competence for reemployment of community health nurses. Furthermore, in order to reinforce assertiveness, institutional support should be accompanied with the efforts of individual level.

OBJECTIVE: To compare the safety and efficacy of intravaginal misoprostol versus intracervical dinoprostone (prostaglandin E2 gel) for cervical ripening and labor induction. METHODS: 60 patients with indication for labor induction and unfavorable cervices were randomly assigned to receive either intravaginal misoprostol or intracervical dinoprostone. 50 microgram tablets of misoprostol were placed in the posterior vaginal fornix every 4 hours for a maximum of 3 doses or dinoprostone 0.5mg was placed into the endocervix every 6 hours for a maximum of 2doses. No more medication was given after either spontaneous rupture of membranes or beginning of active labor. RESULTS: Among 60 patients enrolled, 30 received misoprostol and 30 received dinoprostone. The average interval from start of induction to active labor was shorter in misoprostol group (6.5+/-3.2 hours) than in the dinoprostone group (10.7+/-7.3 hours) (p<0.05). Oxytocin augmentation of labor occurred more often in the dinoprostone group (36.7%) than in the misoprostol group (10.0%) (p<0.05). There was a higher prevalence of fetal distress (23.3% versus 3.3%) and tachysystole (16.6% versus 6.6%) in the misorprostol group than in the dinoprostone group(p<0.05). CONCLUSIONS: Vaginally administered misoprostol is an effective agent for cervical ripening and induction of labor. Furthermore, the cost of misoprostol ( 360/200microgram) is much less than that of dinoprostone ( 42,000/0.5mg). Cost benefits from administration of misoprostol are evident, especially in clinics under system of diagnosis-related group (DRG) : however when given at this dosage, it is associated with a higher prevalence of fetal distress and tachysystole than dinoprostone. Further studies to compare the safety of misoprostole to that of dinoprostone and to delineate an optimal dosing regimen for misoprostol are needed.

BACKGROUND: Chronic exposure to ultraviolet radiation(UVE) nduces photoaging characterized by dry, deeply wrinkled, inelastic, leathery, and irregulaity pigmented skin. UVR also induces solar keratosis and carcinoma, and is a contributing factor in melanoma. Sunscreens are used to prevent solar damage to skin and, if used on a daily lass should significantly reduce the incidence of the chronie photodamaging events. OBJECTIVE: We tried to evaulate the photoaging effects of UVR in the skin and the photoprotective effect of sunscreens. METHOD: We examined the gross and microscopic changes skin of albino hairless Skh : HR-1 mice exposed chronically to ultraviolet B(UVB) and suncreen-treated mice. RESULTS: The skin of the UVB-irradiated mouse shows chear, cteristic signs of photoaging, such as deep wrinkles across the back, and thickened and a hery skin. Histologically, the photoaged skin shows increased epidermal thickness, numeross fibroblasts and inflammatory cell infiltration in the upper dermis, and many enlarged keratering cysts in the lower dermis. By the 20th week, seven of the total of 9 mice(78%) in UVB irradiated mice developed at least one tumor. Histologically, the tumor is a papilloma, but the he are many dyskeratotic cells and loss of polarity in epidermis. Octyl methoxycinnamate or TiO ZnO Talc-treated mic show a significantly decreased wrinkling score, mimmal epidermal hyperplasia, slightly increased dermal cellularity, and lack of proliferation of cysts. The octyl dimethyl PABA-treatd mice shows significantly increased wrinkling score and marked inflammatory infiltration dermis. By the 20th week, only one mouse had developed a tumor in the octyl methoxy irmamate-treated group and no evidence of tumor was seen in the TiO ZnO Talc-treated group. In the octyl dimethyl PABA-treated group, five of 7 mice(71%) developed at least one tumor. CONCLUSION: The skin which is chronically exposed to UVB is subject to photoaging and photocarcinogenesis and regular use of an adequate sunscreen would prevent these photodamaging effects of UVB.

BACKGROUND: Platelet function is directly influenced by lipoproteins, and platelets from hypercholesterolemic patients display increased reactivity which is related to initiation, progression, and development of thromboembolic complications in atherosclerosis. But the exact mechanism of this effect is unclear. METHODS: In this study, total and activated numbers of platelet glycoprotein (Gp) IIb/IIIa were evaluated in twenty patients (7 men; age, 55.4+/-8.7 years) with hypercholesterolemia (plasma total cholesterol level over 240 mg/dL and normal triglyceride level) and twenty one subjects (8 men; 51.1+/-13.7 years) with normal plasma cholesterol and triglyceride levels. Flow cytometry was used to detect the binding of fluorescein isothiocyanate (FITC)-conjugated anti-CD41 or PAC1 to platelet Gp IIb<1/4>/<1/4>IIIa in whole blood. When whole blood was incubated with PAC1, platelets were also activated with adenosine diphosphate (ADP) or thrombin. RESULTS: PAC1 was more bound to unstimulated platelets from patients with hypercholesterolemia (p<0.005), and binding of PAC1 correlated significantly with plasma total cholesteol (r=0.48, p=0.002) and LDL-cholesterol (r=0.47, p=0.002) levels. Binding of PAC1 to unstimulated platelets increased as binding of anti-CD41 increased (r=0.40, p=0.01). On multivariate linear regression analysis, plasma total cholesterol level and binding of anti-CD41 were independent variables that determined binding of PAC1. After ADP- or thrombin-stimulation, binding of PAC1 to platelets and percentage of antibody positive cells were also greater in patients with hypercholesterolemia (p<0.05). There was a significant positive correlation between mean platelet volume and binding of anti-CD41 to unstimulated platelets (r=0.46, p<0.0050), but the latter was not different between hypercholesterolemia and control groups. CONCLUSION: Unstimulated platelets from patients with hypercholesterolemia had similar total number of Gp IIb/IIIa to those from control subjects, but had more activated Gp IIb/IIIa. After ADP- or thrombin-stimulation, platelet Gp IIb/IIIa was also more activated under hypercholesterolemia.

BACKGROUND AND OBJECTIVES: Regular aerobic exercise plays a role in the prevention of cardiovascular diseases, but the risk of primary cardiac arrest transiently increases during vigorous exercise, particularly in sedentary men. There has been a controversy regarding the effect of exercise on platelet functional behavior, which is related to the pathogenesis of coronary ischemia. We evaluated the cytoplasmic free calcium concentration of platelets in healthy men after treadmill exercise. MATERIALS AND METHOD: Five physically active (group I: age, 24.2+/-2.3 years) and five sedentary men (group II: age, 22.4+/-1.4 years) were included in this study. Platelet calcium was measured with fluorescent dye, quin2 before and after treadmill exercise. RESULTS: Platelet calcium levels were increased from 86.8+/-11.8 nM to 128.8+/-15.0 nM in group I (p<0.05) and from 102.6+/-14.4 nM to 162.4+/-26.5 nM in group II (p<0.05) immediately after exercise. Thereafter, platelet calcium levels were decreased in group I, but continuously increased in group II. At fifteen minutes after exercise, platelet calcium concentrations were significantly higher than baseline values in group II (205.8+/-53.9 nM vs 102.6+/-14.4 nM: p<0.05), but not in group I (115.2+/-15.7 nM vs 86.8+/-11.8 nM). CONCLUSION: Cytoplasmic free calcium concentration in platelets were continuosly increased after treadmill exercise in sedentary men but not in physically active men.
