Background: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory reperfusion disorders. We investigated the influence of cerebral reperfusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. Materials and method: Anesthetized Sprague-Dawley rats were undergone ligation of both internal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of internal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. Result: The histopathologic damage scores were 0, 10.2±0.5, 7.6±1.5, 5.9±1.4, 5.0±2.8, 3.5±0.7, and 1.0±0.0 in control, 0, 10,20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). Conclusion: Our results showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion flow after incomplete forebrain ischemia. We believe restoration of reperfusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

저자들은 정신분열병의 일부에서는 태생기 동안 유전 외적인 환경적 요인이 크게 작용할 것이라는 가정 하에 형제 정신분열병 환자군(남 15. 여 7)과 산발성 정신분열병 환자군(남 16, 여 7) 및 정상 대조군(남 16, 여 7)을 대상으로 가족력에 따른 산과적 합병증과 신체 미세 기형을 비교하였다. 산과적 합병증은 Lewis 척도를 이용하여 연구 대상의 어머니와 면담하여 평가하였고 신체미세기형은 Waldrop 척도를 이용하여 측정하였다. 또한 산과적 합병증 및 신체 미세기형과 가족력에에 따라 발병 연령 등의 임상 양상들이 차이를 보이는지 비교함으로써 정신분열병을 좀 더 동질적인 아형으로 나눌 수 있는지를 검토하였다. 1) 형제 환자군, 산발성 환자군 및 정상 대조군의 세균에서 산과적 합병증의 개개의 항목 및 전체 점수의 유의한 차이는 없었다. 신체 미세기형의 경우 입의 미세기 형에서 유의한 차이가 있었으나 그 외에 각 부위별 점수 및 전체 점수에서는 세 군간에 유의한 차이가 없었다. 그러나 대부분의 신체 미세기형 세부 항목 및 전체점수에서 산발성 환자군이 형제 환자군에 비해 높은 신체 미세기형의 점수를 보이는 경향이 있었다. 2) 산과적 합병증의 전체 점수와 신체 미세기형의 전체 점수 사이에 상호 연관성을 찾아볼 수 없었다. 3) 발병연령·정신병리·약물에 대한 반응·병전 기능수준·지연성 운동장애 유무 등의 임상 양상들을 비교하였을때 산발성 환자군과 형제 환자군간에 유의한 차이가 없었다. 4) 산과적 합병증 및 신체 미세기형과 임상 양상들을 비교하였을 때, 형제 환자군에서 분만시간과 회복시 전반적 기능수준간에, 산발성 환자군에서 산과적 합병증의 전체 점수와 발병 연령간에 상관관계가 있었으나 전체적으로 일관된 결과가 도출되지는 못하였다. 위와 같은 결과를 종합하여 볼 때, 산과적 합병증이나 신체 미세기형이 정신분열병의 원인을 밝히는데 유익한 도구가 될 수는 있지만, 가족력 유무에 따라 정신분열병을 보다 동질적인 아형으로 구분하기 힘들다고 생각되었다. In order to test the hypothesis that familial schizophrenics have fewer chances of receiving organic insults during the fetal neural development than sporadic schizophrenics, the authors compared obstetric complications, minor physical anomalies, and other clinical features in sibling schizophrenics, sporadic schizophrenics and controls. Obstetric complications were evaluated by the scale of Lewis, and minor physical anomalies were measured by the Waldrop scale. Sporadic schizophrenics had a significantly higher Waldrop score for mouth than sibling schizophrenics. Although there was some tendency of higher total scores for minor physical anomalies in sporadic schizophrenics, there were no statistically significant differences in obstetric complications and the other minor physical anomalies among three groups. There was no significant correlation between obstetric complications and minor physical anomalies. The clinical features such as age of onset, psychopathology, response to drugs, premorbid functioning, and tardive dyskinesia were not significantly different between sibling and sporadic scizophrenics. In conclusion, while the obstetric complications and minor physical anomalies were suggested to be useful in the search for the cause of schizophrenia, it was difficult to categorize schizophrenics into more homogeneous groups according to family history of schizophrenia using the parameter of obstetric complications and/ or minor physical anomalies.

Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.
