PURPOSE: Since the introduction of short vein bypass (SVB), many have reported its feasibility when long vein bypass (LVB) cannot be performed due to limited vein conduit. However, the presence of inflow-vessel disease may affect graft patency and thus require endovascular treatment prior to surgery. Our study aims to analyze the results between SVB and LVB. MATERIALS AND METHODS: From 2009 to 2013, 27 bypass procedures were reviewed retrospectively. Outcomes such as patency rate, postoperative ankle brachial index (ABI) and limb salvage rate between SVB and LVB were compared. Wound healing time and primary patency rate were analyzed and the former was also analyzed according to the respective angiosome and revascularization type. RESULTS: There were 11 males and 16 females and the mean age was 66.6+/-12.3 years. Twenty four patients had TransAtlantic Inter-Society Consensus (TASC) D and 3 patients had TASC C lesions below knee. The 1-year cumulative patency rate between SVB and LVB were 63% and 66%, P=0.627. The limb salvage rate (100% vs. 73%; P=0.280) and postoperative ABI (0.592 vs. 0.508; P=0.620) were higher in the SVB group than in the LVB group, although the differences were not significant. There was no difference in wound healing time by angiosomal revascularization type. In situ vein graft showed higher patency rate than reversed greater saphenous vein (75% vs. 61%; P=0.00) CONCLUSION: The results of SVB were similar to those of LVB. SVB is feasible in the setting of limited conduit availability, in combination with endovascular treatment in the presence of proximal lesions.

The functional and morphologic cardiac developments are determined by the morphogenesis, growth and remodeling of the heart resulted from the cell proliferation and apoptosis. We studied the distribution of the proliferation and apoptotic activity of myocardial cells according to the developmental stages in embryos of C57bl/6 mice. Serial histologic sections were stained with PCNA and TUNEL method and were analyzed with image analyzer (BMI, Seoul). The ventricular myocardium of an embryonic heart could be divided into trabecular, inner compact and outer compact layers. Proliferation indices at layers of the left ventricular myocardium on embryonal days (ED) 13, 14, 16, 17 and 18 were 19.9%/47.4%/60.4%, 16.1%/45.8%/60.3%, 24.6%/45.6%/38.1%, 23.3%/17.7%/18.3% and 31.2%/28.0%/19.4% (trabecular/ inner compact/ outer compact) and the right ventricle, 11.0%/34.4%/60.5%, 23.0%/44.0%/69.0%, 29.2%/42.9%/35.1%, 30.4%/30.5%/22.3% and 32.4%/28.4%/16.3%. The apoptotic indices of the left ventricle/VIF were 0.23%/3.66% on ED 13-14, 0.42%/1.31% on ED 16 and 0.05%/0.60% on ED 17-18. The results show that the proliferation of the myocytes was maximal at the outer compact layer on ED 13 and 14 but lowest on ED 17 and 18. This decrease was more pronounced at the left ventricle. The innermost trabecular layer showed a constant proliferation activity of 11.0-32.4%. The presence of spatiotemporal differences in the cell proliferation reveals regional regulation in the developmental timing of cardiac development. Functional maturation is considered to be responsible for the change of proliferation activity. The apoptosis was most frequent and intense in the VIF and crux throughout the periods of each embryonal day where as rarely seen in the ventricular myocardium, especially in the trabecular layer of myocardium. These findings suggest that the apoptosis plays the role in the development of atrioventricular, ventriculoarterial septation and valve formation. Our results also reveal that the participation of apoptosis in formation of the trabeculation can be denied.

BACKGROUND: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory repefusion disorders. We investigated the influence of cerebral repefusion 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 infernal 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 infernal 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 insults showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion know after incomplete forebrain ischemia. We believe restoration of repefusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

Purpose: The purpose of this study was to analyze the factors influencing the health promoting behavior(s) of office worker males in the COVID-19 pandemic by applying Pender’s health promotion model. Methods: The participants in this study were 149 male office workers at companies located in S, G and S cities. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson’s correlation coefficient and a stepwise multiple regression using the SPSS Window 25.0 program. Results: The subject’s health promoting behaviors and prior related behaviors (r=.58, p<.001), perceived benefits of action (r=.41, p<.001), self-efficacy (r=.53, p<.001), social support (r=.39, p<.001), self-esteem (r=.47, p<.001) and commitment to a plan of action (r=.67, p<.001) showed a high positive correlation. The factpors affecting the subjects’ health promoting behaviors were the commitment to a plan of action (β=.35, p<.001), self-esteem (β=.27, p=.005), prior related behavior (β=.26, p<.001), health status (good) (β=.20, p=.001) and self-efficacy (β=.14, p=.047). These variables explained 63.0% of the subjects’ health promoting behaviors. Conclusion During the COVID-19 pandemic, subjects are more likely to be exposed to disease due to reduced outdoor activity time and irregular eating habits due to the strengthening of social distancing. Health promoting behaviors are an important concept that can maintain health and prevent diseases. To improve the health promoting behaviors of men engaged in office work, it is necessary to develop and operate a health promotion behaviors program considering those variables.
