BACKGROUND: The severity of several chronic inflammatory diseases was reported to be associated with polymorphism of the IL-1 receptor antagonist gene(IL-lrn). OBJECTIVE: This study was performed to study the polymorphism of the IL-1rn in vitiligo and in the normal Korean population. METHODS: Thirty one cases of vitiligo and seventy nine normal Koreans as control were studied for the polymorphism of IL-1 rn. RESULTS: The frequency of allele 2 of the IL- I rn in 31 patients with vitiligo was compared with that of the 79 healthy controls. The frequency of allele 2 was 1.6% in vitiligo patients and 3.8% in the normal controls. CONCLUSION: There was no significant difference in the frequency of allele 2 between the vitiligo patients and normal controls.

PURPOSE: This study aimed to examine the relationships between the N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels with the sociodemographic and clinical factors, self-care behaviors, and the physical symptom experiences in patients with heart failure. METHODS: This cross-sectional study utilized a convenience sample of adult outpatients and inpatients who attended a cardiology department in a tertiary hospital in Seoul, Korea. The data from 154 patients with heart failure were collected using a questionnaire, and their clinical data were extracted from their electronic medical records. RESULTS: Compared with the patients with high NT-proBNP levels, those with low NT-proBNP levels had significantly lower physical symptom experiences scores. Patients with low- and mid-NT-proBNP levels were more likely to be employed compared with those with high NT-proBNP levels. Patients with low NT-proBNP levels had higher left ventricular ejection fractions, and were less likely to have arrhythmias and comorbidities. CONCLUSION: The results from this study showed that patients with more severe heart failure had higher physical symptom experiences scores; hence, individualizing treatment approaches based on heart failure severity is necessary.

PURPOSE: This study was conducted to investigate the effects of core basic nursing education using cellular phone video recordings on self-confidence in performance, achievement, and practice satisfaction. METHODS: The research design was a nonequivalent control group modified and non-synchronized design. The participants were assigned to either the experimental (n=60) or control group (n=67). During one semester, the experimental group received training for 10 selected core basic nursing skills using cellular phone video recording. The control group, also for one semester, received training with traditional practices. Self-confidence in performance and practice satisfaction were measured using a questionnaire, and achievement was evaluated by professors at the conclusion of the semester. Collected data were analyzed using t-test and Pearson correlation coefficients. RESULTS: Self-confidence in performance increased significantly after training in the experimental group (t=7.94, p<.001). The experimental group showed significantly higher self-confidence in performance (t=2.39, p=.018) and achievement (t=2.40, p=.018) compared to the control group. However, the difference in practice satisfaction was not statistically significant. CONCLUSION: The results indicate that cellular phone video recording is effective in improving self-confidence in performance and achievement of core basic nursing skills.

OBJECTIVE: Recently, the incidence of elderly primipara is increasing. Thus, impact of old age on pregnancy outcomes became important. Our purpose was to assess the effect of maternal age on pregnancy outcomes. METHODS: 73 cases of the elderly primipara over 35 years at the department of obstetrics and gynecology, Chon-ju presbyterian medical center, from Jan. 1, 1995 to Dec. 31, 1998, were compared with 73 cases randomly chosen young primiparas during same period. RESULTS: Elderly primipara had higher rate of infertility and spontaneous abortion history, antenatal complications, cesarean section, poorer neonatal outcome than young primipara. CONCLUSION: The pregnancy outcome of elderly primipara is considered to be less favorable than those of young primipara. Careful antenatal and intrapartal care should be performed for the elderly primipara. We think that many clinical study of congenital anomaly in elderly primipara will be necessary.

Injury of the ankle ligaments is one of the most common sports-related injuries. Although there are some debates as to the best initial treatment for an acute tear of a lateral ligament, persistent functional instability of the ankle develops in approximately 20% of patients regardless of the type of initial treatment. In these patients, late reconstruction of the lateral ankle ligaments may become necessary. Among 13 cases which have been operated with Larsen procedure using peroneus brevis tendon from March 1991 to February 1993, the 11 cases followed up over 1 year were examined clinically and radiologically. We introduced the clinical analysis and results with the brief review of the literatures. 1. The indication of surgical treatment was the ankle instability which had differences over 10° in talar tilting angle or over 3mm in anterior displacement compared wit the uninjured site. 2. The postoperative results were 5 cases in excellent and 4 in good. 3. The Larsen procedure was considered a good method to anatomically and simply stabilize both the ankle and subtalar joint and to fix tendon depending on the type of instability.

OBJECTIVE: In the human body the embryo initially gmws in the fallopian tube which is maintained in an 3-8% O2 concentration environment, and various substances such as growth factors and antioxidants present in tbe tubal fluid assists in maintaining a healthy environment for embryo development. But in IVF programs embryo cultures are conducted in incubators with 21.9% O2 and 5% CO2 condition, and such high oxygen concentrations have been reported to increase the production of oxygen free radicals within the embryo and is detrimental to the growth and development of the embryo. The objective of this study, therefore, is to determine the culture conditions which will decrease oxygen free radical production and thereby minimize the injury to the embryo. METHODS: Six to eight week old ICR strain mice embryos were cultured in 5% or 21.9% O2 conditions and in culture media to which inaement concentrations of superoxide dismutase (SOD) had been and the H2O2 concentration within the embryo, embryo developmental rate, and degree of fragmentation of the embryos was investigated. RESULTS: The control gmup embryos which were cultured in 21.9% O2 condition without addition of SOD showed developmental arrest at the 2-cell stage or fragmentation, while those cultured in 21.9% O2 condition with addition of SOD showed development to the blastocyst stage with deaeased fragmentation. In particular, the blastulation and fragmentation rates were the lowest in the group to which 500 IU/ml of SOD was added, but in the 5% O2 enviranment group many embryos reached the blastocyst stage and with no difference in frapnentation with or without addition of SOD. The HO relative intensity (120.5+/-20.2) within the embryos cultured in 21.9% O2 environment without SOD was significantly higher than that (56.8+/-10.8) of group with SOD (p<0.05). As showing that in the 5% O2 environment group without SOD it was 43.8+/-7.8 and in the group with SOD it was 37.3+/-5.4, the H2O2 concentration within embryos cultured in 5% 02 condition was significantly lower those that of 21,9% 02 environment regardless of SOD addition (p<0.05). CONCLUSION: The optimal oxygen concentration in incubator for mice embryo cultures is that which is similar to the 5% 0 concentration in vivo. When 20% 02 incubators are routinely used, the addition of SOD to the culture media will decrease the H2O2 concentration within the embryos with subsequent improvement in development. The optimal concentration which should be used is thought to be 500 IU/ml. It is suggested that the use of the above method in human IVF-ET programs will lead to improved embryo quality and enhanced pregnancy rates.
