The use of hormonal stimulation in human in vitro fertilization and embryo transfer (IVF-ET) leads to increased production of embryos for ET. So to avoid high pregnancies and to allow conception in future, unstimulated cycles, cryopreservation of spare embryos is desirable. One of the improvement of cryopreservation methods is vitrification. We cryopreserved mouse day 3 embryos by vitrification using the three different vitrification solution (EFS40, VSll and VS3a). EFS40 solution is consisted of 40% (v/v) ethylene glycol, Ficol170 30% (w/v) and 0.5M sucrose and VSll is 6.0M ethylene glycol and 1.8M glycerol. And VS3a is 6.5M glycerol and 6% (w/v) BSA (bovine serum albumin). First we tested the toxicity of three vitrification solution by exposure to these solution during 3 min. After washing by thawing solution, the survival rates of each groups are 95.5%, 90.9% and 84.4% (EFS40, VS11 and VS3a). High percentages of them developed to expanded blastocyst and hatching embryos in culture 48hrs 94.2%, 97.7%, 100% and 97.4% (no treatment group, EFS40, VS11 and VS3a). So there is no significant differences among the each group. Second, after thawing of vitirfied embryos, the survival rates of each groups are 96.8% (slow freeze), 94.1% (EFS40), 85.5% (VS11) and 80.0% (VS3a, P vs. no freeze or EFS40 is 0.01). Vitrified embryos exhibited a high rate of development in vitro after 48hrs culture. The percentages of each group to blastocyst and hatching embryos are 88.7% (no freeze), 91.8% (slow freeze), 93.4% (EFS40), 87.7% (VS11) and 73.0% (VS3a, P vs. other group is 0.01). The results suggest that there is no significant differences in exposure of various vitrification solution and day 3 mouse embryos can be vitrified in solution EFS40 and VS11 by simple procedure.

Acute infectious myocarditis in children can be caused by many pathogens, including bacteria, viruses, fungi and protozoa. Patients may be asymptomatic or may have 'flu-like symptoms' to life-theratening arrhythmias or sudden death. We herein report a case of acute myocarditis complicated by complets and permanent AV block, associated with Salmonella group B gastroenteritis in a previously healthy 5-year-old boy. Presenting symptoms were dyspnea, cyanosis, vomiting, and diarrhea. Electrocardiography on admission showed very slow ventricular escape rhythm at 37 beats/minute. He was treated with antibiotics, inotropic agents, ventilatory support, and transvenous temporary pacemaker. Ten days later, permanent dual chamber pacemaker was implanted. All three consecutive stool cultures done after admission grew Salmonella group B. His ventricular function recovered rapidly and completely and he became fully active 2 months after the onset. However, his conduction system was totally destroyed and at last follw up evaluation 2 years after the onset, he is still totally dependent on the pacemaker without any escape rhythm.

Journal of the Korean Dietetic Association 2003;9(4):278-287
This study was performed to investigate nurses' perception for nutrition education. The subjects of this study were 197 nurses and 94 nursing assistants working at hospitals in the Kyung-nam area. The survey was conducted by using a self-administered questionnaire in November, 2001. The results were as follows : Sixty-seven point seven percent of the subjects were nurse, 32.3% were nursing assistant. Average age of subjects was 26.9 years old, average nursing experience was 5.7 years, and 70.7% of the subjects graduated from a junior college. The average nutrition knowledge score was 14.3+/-2.5 out of possible 20 points. Seventy-four point two percent of the subject responded that nutrition education is very necessary for patient, and positive responses in the nurse were higher than that nursing assistant(p<0.001). Only 8.6% of the subjects had nutrition education training. The perceptions about a suitable person for nutrition counseling and nutrition education indicated dietitian(69.3%) and nurse(21.3%). Fifty-two point eight percent of the subjects responded that they would not participate in nutrition education themselves and the main reason for this was that they believed lack of expert knowledge(43.4%), and that such courses should be taught by specialist(40.5%). Forty-eight point eight percent of subjects had nutrition counseling experience for patient, and nurses, married nurses and those over 2 years of nursing careers had significantly higher nutrition counseling experience for patient than nursing assistant, unmarried nurses and those under 2 years of nursing careers(p<0.05~p<0.001)

Psoriasis is characterized by disregulation of keratinocyte growth with profound epidermal hyperplasia. Keratinocyte hyperplasia in psoriasis may be expained in part by overproduction of growth factor, and by altered metabolism of the epidemal growth factor receptors (EGFR) in affected skin. The expression of epidermal growth f ictor receptor was investigated by Northern blot and slot-blot analysis of total RNA extrated from biopsies of normal skin and psoriatic lesions. In Northern blot analysis, EGFR-specific mRNA transcripts from psoriatic tissues demonstrated the specificity of hybridizarion with a EGFR mDNA probe. The size of EGFR mRNA transcript was 6.7kb in psoriasis lesions which showed no change of quality. In slot-blot analysis, the levels of EGFR mRNA in poriasis revealed a 1.2 fold to 4.1 fold elevation when compared to normal skin. EGFR were present in all epidermal layers by immunoperoxidase staining, whereas in normal skin they were primarily present in the stratum basalis. These results indicate that the increased expresion of the EGFR gene may be, in part, responsible for the hyperproliferation of the epider nis and that retained EGFR may reflect incomplet; abnormal differentiation in active porasis. This altered process of EGFR metabolism may be involved in the pathogenesis of psoriasis.

PURPOSE: This study was conducted to identify ethical climate factors in hospitals and analyze their influence on job satisfaction and organizational commitment. METHODS: A convenience sample of 196 nurses from one national university hospital in J city participated in this descriptive study survey. Instruments included the Ethical Climate Questionnaire, Job Satisfaction Scale, and Organizational Commitment Scale. Cronbach's alpha and factor analysis were done to test reliability and construct validity of the scales. Data were collected from March 15 to March 25, 2013 and analyzed using descriptive statistics, one-way ANOVA, t-test, Pearson correlation, and multiple regression with SPSS/WIN 18.0. RESULTS: Seven ethical climate factors were identified; laws and professional codes, social responsibility, company rules and procedures, self-interest, personal morality, efficiency, and friendship. Factors influencing job satisfaction were friendship (beta=.25), social responsibility (beta=.20), laws and professional codes (beta=.20), and educational level (beta=.27), explaining 37.6% of variance in job satisfaction. Factors influencing organizational commitment included social responsibility (beta=.29), friendship (beta=.27), laws and professional codes (beta=.23), and age (beta=.19), with explanatory power of 44.6%. CONCLUSION: Results can be used as preliminary data for developing new strategies to establish positive ethical climates in hospital environments and thus enhance nurses' job satisfaction and organizational commitment.

OBJECTIVE: This survey assessed the prevalence and type of sexual dysfunction in middle-aged women regarding sexually related personal distress and examined the prevalence of perceived sexual dysfunction and perceived partners' dysfunction by women. METHODS: One-hundred ten healthy community-based middle-aged women participated voluntarily, and validated question- naires of the Female Sexual Function Index(FSFI) and the Female Sexual Distress Score(FSDS) were used. RESULTS: The percentage of women having sexual dysfunction and sexual distress were 67% and 32% respectively according to the cut-off of FSFI and FSDS. The average score of FSFI was 23.5(s.d.=5.7), which was lower than the cut-off of FSFI, while the average score of FSDS was 13.2, which was in range of a normal score. When considering the two concepts simultaneously, the women were categorized into 4 groups: sexually stressed dysfunction group (24.8%), sexually depressed group(42.2%), sexually healthy group(25.7%), and sexually hyperactive group (7.3%). The percentage of women reporting sexual problems was 24.3%, while the percentage of women reporting sexual dysfunction in their partner was 29.9%. CONCLUSIONS: The results indicate a high rate of sexual dysfunction and sexual distress in middle-aged women. However, considering the relationships between sexual dysfunction and sexual distress, almost two thirds were in the sexually depressed group among the women having sexual dysfunction.

This study was performed to assess the effect of one year's of meal service for home-staying urban elderly with low incole on their nutritional status. One hundred and eighty three subjects, who had already completed the first nutritional survey, were assigned to two group : meal served(served) and non-meal served(non-served). A meal containing approximately on half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After on year of meal service, follow-up-nutritional survey was done and changes of parameters were analyzed with paired t-test. Served female showed signficantly increased intake of riboflavin and calcium, while non-served female showed significantly decreased intake of calcium. Serum total protein, serum albumin and serum cholesterol were significantly increased in female regardless of meal service. Served remale was observed with significantly elevated LDL-cholesterol, whereas non-served female showed singnificantly lowered HDL-cholesterol. Significantly decreased serum iron, serum transferrin saturaion and significantly increased TIBC were observed for female regardless of meal service. But the proportion of anemic elderly according to Hb or serum iron was decreased more in served group. Female showed significantly increased serum zinc and copper regardless of meal service, whereas only served male showed significantly increased serum copper.

Acetylcholine is one of the major neurotransmitters in visual system of rats. Cholinergic, serotonergic and gamma-aminobutyric acid(GABA) ergic projections are known as modulators of visual processing. The purpose of this study was to examine the effects of unilateral orbital enucleation on the amount of acetylcholine and its receptor bindings in dorsolateral geniculate body, superior colliculus and visual cortex of rats, and on motor activites. The amount of acetylcholine was measured by gas chromatography; whereas [3H]quinuclidinyl benzilate(QNB) bindings to muscarinic receptors were examined by autoradiography. Motor activity was measured by activity meter for 24 hours. The results of this study were as follows: 1. The amount of acetylcholine in superior colliculus significantly increased at 1 week after enucleation, but it decreased at 2 and 4 weeks after enucleation. In visual cortex, the amount of acetylcholine did not change at 1 week after enucleation, but it significantly decreased at 2 and 4 weeks after enucleation. 2. After enucleation, [3H]-QNB binding to muscarinic receptors gradually decreased over the 4 weeks in dorsolateral geniculate body, superior colliculus and visual cortex. 3. Locomotor activity of rats did not show any change at 1 week after enucleat ion, but it decreased at 2 and 4 weeks after enucleation. In conclusion, unilateral orbital enucleation resulted in a reduction in the amount of acetylcholine and muscarinic receptors in rat visual system, which was speculated to be a major cause of a decrease in physical activity.

BACKGROUND: Alterations in ventricular loading conditions lead to changes in action potential duration via mechanoelectrical feedback. A decrease in load immediately leads to prolongation of repolarization. QT interval and QT dispersion were measured to determine the long-term effect of changes in ventricular systolic load on the ventricular repolarization. METHOD: Corrected QT interval and QT dispersion were measured in 26 patients before and 3-6 months after valvuloplasty for pulmonary stenosis. To determine the effect of ventricular load on ventricular repolarization, patients were divided in 2 groups; Group 1 was those patients with a greater than 30 mmHg and Group 2 was those patients with a less than 30 mmHg decrease in right ventricular systolic pressure. RESULTS: Corrected QT interval (412.6+/-14.5 msec vs 426.4+/-16.8 msec, p < 0.05) and QT dispersion (35.0+/-7.3 msec vs 45.7+/-14..1 msec, p < 0.05)were increased significantly only in Group 1 after vlavuloplasty. CONCLUSION: It suggested that mechanoelectrical interactions are operative for long duration in humans that changes in ventricular load after successful pulmonary valvuloplasty showed long-term effect on the ventricular repolarization.
