PURPOSE: The purpose of this study was to determine the effect of DHEA on hindlimb muscles(soleus, plantaris and gastrocnemius) in a focal brain ischemia model rat. METHOD: Twenty-seven male Sprague-Dawley rats were randomly divided into three groups: CINS(cerebral ischemia + normal saline), CIDH(cerebral ischemia + DHEA), or SHNS(sham + normal saline). Both the CINS and CIDH groups underwent a transient right middle cerebral artery occlusion operation. In the SHNS group, a sham operation was done. 0.34mmol/kg DHEA was administered daily by an intraperitoneal injection for 7days. RESULT: The muscle weight, muscle fiber cross-sectional area of the Type I muscle fiber of soleus and Type II muscle fiber of plantaris and gastrocnemius, myofibrillar protein content of gastrocnemius, and muscle strength in the CINS group decreased compared with the SHNS group. The muscle weight, muscle fiber cross-sectional area of the Type II muscle fiber of plantaris and gastrocnemius, myofibrillar protein content of soleus, and muscle strength in the CIDH group increased compared with the CINS group. CONCLUSION: It was identified that muscle atrophy could be induced during 7 days after a cerebral infarction, and DHEA administration during the early stages of a cerebral infarction might attenuate muscle atrophy.

PURPOSE: The purpose of this study was to explore the experiences of nursing students in Korea who used concept mapping for understanding pathophysiology. METHODS: The data were collected using an open-ended questionnaire from 83 sophomore nursing students after studying concept mapping in pathophysiology class. Each group consisted of five nursing students submitting four concept maps regarding cell injury, inflammation, infection, and neoplasm. After familiarity with concept mapping, the participants wrote their experiences anonymously on sheets of paper. The submitted materials were analyzed via qualitative content analysis. RESULTS: The collected materials were classified into 3 themes, 8 categories, and 18 subcategories. Three themes emerged: (1) awareness of capabilities, (2) difficulties of completion, and (3) benefits of application. CONCLUSION: The study revealed that participants experienced self-capabilities, and the difficulties and benefits of concept mapping. Concept mapping also provided the opportunity for nursing students to realize communication skill improvement by active group discussion within a group.

PURPOSE: The purpose of this study was to review previous literature with an aim to explore the sleep disturbance level after a patient undergoes cataract surgery using an integrative review. METHODS: We used the key words, ‘cataract surgery’, ‘sleep’, and ‘intraocular lens’ to find peer-reviewed publications in seven databases. Among 450 searched articles, eight articles were selected after exclusion of articles that did not meet the criteria. RESULTS: Five of the articles submitted that subjective sleep quality of the patients with blue-filtering intraocular lens (BF-IOL) implant improved as compared to that before surgery. The change of saliva melatonin concentration after BF-IOL implant did not coincide in two of the articles. Two of the articles reported an increased level of intrinsically photosensitive retinal ganglion cells response after BF-IOL implantation. CONCLUSION: The published studies stated that BF-IOL implant did not have any negative impact on quality of sleep among cataract patients suffering with poor sleep. Rregardless of intraocular lens type, cataract surgery may increase photoreception of intrinsically photosensitive retinal ganglion cells one year after surgery although the mechanism was not clear. It is necessary to identify various factors influencing the quality of sleep such as gender and activities among cataract patients with BF-IOL implant in the future.

Purpose: The purpose of this study was to review primary research exploring the correlations between the levels of serum testosterone and the prostate-specific antigen (PSA) in healthy men without prostate diseases. Methods: An integrative review was conducted using the Whittemore & Knafle (2005) framework. The keywords, ‘testosterone & prostate-specific antigen’, ‘testosterone & PSA’ and ‘healthy men’ were used to search peer-reviewed publications in six databases. Among 1,959 searched articles, eleven articles were selected after excluding articles that do not meet inclusion criteria. Literature quality was moderate (Level 3). Results: As a result of this study, it was confirmed through the nine articles that healthy adult men showed no significant correlation between the serum testosterone and the PSA. Conversely, two articles presented that the serum PSA correlate positively with the testosterone. In particular, it is inferred that the effect of the serum testosterone and the PSA secreted into a 24-hour circadian rhythm with different amplitudes and slopes would have had great influence. However, it does not consider the factors affecting the testosterone and the PSA, such as race, liver disease, and BMI, so there is insufficient empirical data to clearly explain the relationship between the testosterone and the PSA. Conclusion The correlation between the serum testosterone and the PSA in healthy adult men is insignificant in relation to the circadian rhythm of the testosterone and the PSA secretion. It is that a large-scale study including various influencing factors using new biochemical indicators such as pro PSA be conducted in the future.

Purpose: The purpose of this study was to analyze the experiences and perceptions of nursing students related to their cadaver practice through an integrative review. Methods: An integrative review was conducted using Whittemore and Knafl’s framework published in 2005. The key words, “nursing students & cadaver” and “nursing students & anatomy” were used to search peer-reviewed publications in six databases. Among 373 searched articles, 15 articles were selected after excluding articles that did not meet the inclusion criteria. The literature quality was moderate (levels C and B). Results: The results from the 15 selected studies were integrated and classified into seven themes: “anxiety and discomfort,” “gratitude and respect for donors,” “dignity of the human body and life,” “acceptance of death,” “getting closer to the nursing profession,” “enhanced understanding and memory of the human body” and “enhancement of learning motivation.” Conclusion In conclusion, cadaver practice provided an opportunity to form values about the dignity of life and death, helped nursing students understand the human body, and motivated them to approach the profession of nursing. It is suggested to develop integrated cadaver practice programs that incorporate bioethics, spiritual nursing, and the vocation of the nursing profession.

Thirty one infants of diabetic mothers(IDM) who had been admitted in Neonatal Intensive Care Unit at Chonnam University Hospital from January 1987 to July 1991 were studied for evaluation of their perinatal outcome and prognosis. The results were as follows; 1) The distribution of diabetic mothers according to modified White's classification was GD & class A in 12 cases(38.7%), B in 16 cases(51.6%), C in one case, D4 in one case, and R in one case. 2) Of the 31 diabetic mothers, 8(25.8%) had a history of infertility or stillbirth, 20(64.5%) had prognostically bad signs of pregnancy (PBSP), and 12(38.7%) were treated with insulin and/or oral hypoglycemic agent during pregnancy. 3) C-section rate was 32.2%, and the rates of shoulder dystocia and birth asphyxia were 35.5% and 29.0%, respectively. 4) The rates of large for gestational age were 75.0% in class GD & A, 68.8% in class B, and the rates of small for gestational age were 8.3% and, 6.3% respectively, Characteristic face with body composition was noted in all babies, hepatosplenomegaly in 90.3%, heart murmur in 41.9%, respiratory distress syndrome in 12.9%, transient tachypnea of mewborn in 19.4%, hypertrophic cardiomyopathy in 40.0%, and seizure in 6.5%. 5) Laboratory abnormalities were hypoglycemia in 77.4%, hyperbilirubinemia in 83.9%, polycythemia in 16.1%, hyperinsulinemia in 45.5%, hypercalcemia in 22.6%, and hypomagnesemia in 23.1%. 6) Birth injuries were noted in 61.3%, The most common were caput succedaneum and/or cephal-hematoma, brachial palsy, and fracture. Congenital anomalies were noted in 16.1%. The most common were musculoskeletal, cardiovascular, and gastrointestinal anomalies. 7) In the short term follow up of 19 patients, there were mild developmental delay in 2 cases, cerebral palsy in 2 cases, and epilepsy in 1 case. These results suggested that infants of diabetic mothers had greater morbidity than infants of nondiabetic mothers. Therefore, long term follow up is recommended to achieve their normal growth and development.

PURPOSE: This study examined relationships among stress, stress coping strategies, and somatization in mothers-in-law from multi-cultural families in a rural area. METHODS: Elderly mothers-in-law (n=227) living with foreign daughters-in-law completed a self-reporting questionnaire. Data were collected from April to August 2009. Questions related to stress (Visual Analog Scale, VAS), coping strategies (Coping Strategy Scale) for stress, and somatization (Symptom Check List 90, Revised). SPSS/WIN 12.0 program was used for descriptive analysis, t-test, one-way ANOVA, Pearson correlation, and multiple regression analyses. RESULTS: Subjects had a moderate level of stress (5.03). There were significant differences in stress level according to age, educational level, religion, chronic disease, health status, number of children, agreement of an international marriage of her sons, satisfaction in living with a foreign daughter-in-law, and family conflict. Stress showed a significant positive correlation with offensive coping strategy, passive strategy, and somatization. Stress, offensive coping strategy, and passive coping strategy affected the level of somatization. CONCLUSION: In a family situation involving co-habitation of mother- and foreign daughter-in-law, increased stress experienced by the mother-in-law can lead to increased offensive and passive coping strategies, and increased somatization. More effective means of stress reduction are needed for mothers-in-law from multi-cultural families.

PURPOSE: The purpose of this study was to determine the effect of Dehydroepiandrosterone (DHEA) administration alone or exercise combined with DHEA before steroid treatment on rat hindlimb muscles. METHODS: Male Sprague-Dawley rats were assigned to one of three groups: a steroid group (S, n=10) that had no treatment for 7 days before steroid treatment; a DHEA-steroid group (DS, n=8) that had 0.34 mmol/kg/day DHEA injection once a day for 7 days before steroid treatment and an exercise?steroid group (EDS, n=9) that ran on the treadmill combined with 0.34 mmol/kg/day DHEA injection for 7 days before steroid treatment. At 15 days all rats were anesthetized and soleus, plantaris and gastrocnemius muscles were dissected. Body weight, food intake, muscle weight, myofibillar protein content and cross-sectional area of the dissected muscles were determined. RESULTS: The DS group showed significant increases (p<.05) as compared to the steroid group in body weight, and muscle weight of gastrocnemius muscles. The EDS group showed significant increases (p<.05) as compared to the S group in body weight, muscle weight, myofibrillar protein content, and Type II fiber cross-sectional area of soleus, plantaris and gastrocnemius muscles. CONCLUSION: Exercise combined with DHEA administration before steroid treatment prevents steroid induced muscle atrophy, with exercise combined with DHEA administration being more effective than DHEA administration alone in preventing muscle atrophy.
