The fashion of vascular anastomosis, end-to-end or end-to-side (E-to-S), are depended upon surgeon's preference or surgical situations. In E-to-S anastomosis two different methods of arteriotomy are applicable but it has been suggested the type, either elliptical or slit arteriotomy, play a different role in the flow hemodynamics. We thought that the difference is more considerable in microvascular surgery. This study examines the effects of elliptical versus slit arteriotomy on morphologic vessel patency. Twenty male Sprague-Dawley rats were divided into two groups of ten rats each. Both carotid arteries were selected as a experimental model. During the procedures the rat brain was tolerable to ischemia and all animals were survived after operations. The morphologic analysis of anastomosis site was through resin-casting method with scanning electromicroscopic examination. The results showed notable difference between two groups in three-dimensional morphology at two-month of operation. This difference may affect the flow hemodynamics and long-term vessel patency. In microvascular anastomosis, the mortpologic difference of the elliptical arteriotomy is worse than slit arteriotomy which compromises the vessel circumference.

A symbiotic relationship between humans and the microbiota is critical for the maintenance of our health, including development of the immune system, enhancement of the epithelial barrier, and acquisition of nutrients. Recent research has shown that the microbiota impacts immune cell development and differentiation. These findings suggest that the microbiota may also influence adjuvant and vaccine efficacy. Indeed, several factors such as malnutrition and poor sanitation, which affect gut microbiota composition, impair the efficacy of vaccines. Although there is little evidence that microbiota alters vaccine efficacy, further understanding of human immune system-microbiota interactions may lead to the effective development of adjuvants and vaccines for the treatment of diseases.

OBJECTIVES: The objective of this study was to identify the association of food intake with bio-physiological indicators: blood pressure, body mass index (BMI), waist/hip ratio (WHR), cholesterol and urine sugar among rural people. METHODS: The subjects were 890 inhabitants from 14 towns of G County in Honam province. Data were collected by interview and self-reported with structured questionnaires from April 6th to 30th 2005. Data were analyzed with the frequency, percentage, t-test, chi-square-test, ANOVA, Scheffe test and ANCOVA using SPSS 12.0 program. RESULTS: Pre-hypertensive and hypertensive group was 27.0%, overweight and obese 27.1%, more than 0.90 in WHR 42.0%, more than 201 mg/dl of cholesterol 23.9%, and positive urine sugar was 8.7% in general. Among eleven food groups, fruit intakes were more effective in normotensive group than in the others. Vegetables, liquors, and milk products were 0.90 WHR more effective than the others. Milk products and liquors in BMI, and grains, beans and seaweed in low cholesterol group were more effective than the others. CONCLUSIONS: Bio-physiological indicators are related significantly only with fruits, milk products, meats, cereal and liquors among eleven food categories. Further study on the relationship between food intake, physical activities, smoking, drinking and lifestyle with bio-physiological indicators are suggested.

Distortion of vowels in dysarthria associated with amyotrophic lateral sclerosis can be detected at the perceptual, physiological, and acoustical levels of analysis. Sound spectrography was used to analyse the formants of vowels which reflect position and space of articulatory organs. We analyse status and progression of dysarthria in 54 year old women with amyotrophic lateral sclerosis using sound spectrography. Target formant frequencies were measured from select words containing the vowels /a/, /e/, /i/, /o/, /u/. Results revealed that dysarthric patient exhibited smaller vowel space areas and less systematic changes in vowel spaces for pronouncing different vowels in comparison with normal control. Changes of vowel formants in sound spectrographic analysis reflected progression of dysarthric symptom in this patient. We conclude that acoustic analysis of vowels using sound spectrography is a useful tool to visualize and quantitatively analyse the severity and progression of dysarthria due to paralytic articulatory organ.

Computer-aided diagnosis (CAD) has become one of the major research subjects in medical imaging and diagnostic radiology. Many different CAD schemes are being developed for use in the detection and/or characterization of various lesions found through various types of medical imaging. These imaging technologies employ conventional projection radiography, computed tomography, magnetic resonance imaging, ultrasonography, etc. In order to achieve a high performance level for a computerized diagnosis, it is important to employ effective image analysis techniques in the major steps of a CAD scheme. The main objective of this review is to attempt to introduce the diverse methods used for quantitative image analysis, and to provide a guide for clinicians.

PURPOSE: The aim of this study was to evaluate the efficiency of community visiting health service units using DEA and to compare the results with those of traditional evaluation methods. METHODS: Data were collected using 2008 annual reports of 10 districts in one city. Input variables were number of staff and operational budget per year and output variables were number of managed household per nurse, rate of controlled hypertension, and diabetes mellitus. EMS Window version 3.1 was used to measure efficiency score and bootstrapping Chi-square test was applied to identify differences between efficient and non-efficient unit by organizational factors. RESULTS: The average efficiency score of 10 community visiting health services was about 66%. Only two of the units operated program efficiently. The career of the staff was one among other factors associated with efficiency. The evaluation results from the traditional method and DEA were totally different. CONCLUSION: These results indicate that, evaluation methods have very important and significant effects on the evaluation results of community visiting health service units. The DEA method is recommend as an alterative method for evaluating community visiting health service.
