Background: Testicular rupture is a surgical emergency which command immediate repair. If surgery is delayd, a hematoma causes severe pain and loss of spermatogenesis as well as hormonal functions. Scrotal ultrasonography has been helpful in early diagnosis of testicular rupture. But disadvantage of ultrasonography include a relatively low signal-to-noise level, tissue nonspecificity, lack of contrast media, a small field of view, and dependence on the operators skill and the patients physique. Also the diagnostic accuracy, sensitivity or specificity of scrotal ultrasonography was variable in regard to authors. And so, a diagnostic accuracy of scrotal ultrasonography was evaluated in scrotal trauma. Methods·. We reviewed 38 patients of scrotal trauma from May, 1994 to March, 1998. 6 patients were treated conservatively fellowing sonography and 10 patients treated only surgical exploration without ultasonography Surgical exploration was performed in 22 case, which were evaluated by ultasound before surgical treatment. In a such 22 cases, diagnostic accuracy of scrotal ultasonography was evaluated. Results: We compared ultrasound before treatment with surgical exploration finding in a such 22 cases. The ultrasonographic features in 7(31.8%) out of 22 cases, which showed testicular ruptured, but surgical exploration revealed testicular rupture in5 and epididymal rupture in 1, simple hematocele in 1. In 15(68.2%) out of 22cases the simple hematocele was diagnosed by ultrasonography, but surgical finding feature in of the 7 cases revealed testicular rupture, epididymal rupture in 1, simple hematocele in 7. The sensitivity and specificity for the ultrasonography are 42.9% and 87.5%, and the positive and negative predictive values are 86.5%and 46.7%, respectively. Ultrasonography is low sensitive in identifying testicular rupture. Conclusion: 7trasonography include a relatively low signal-to-noise level, tissue nonspecificity, lack of contrast media, a small field of view, and dependence on the operators skill and the patients physique. Therefore, early surgical exploration for saving the testis should be performed that sonographically by seeing hypoehoic peripheral lesions and disappearance of normal ovoid form of testis, hematocele in scrotal sac.

The effects of chitosan on the germination and growth of mungbean sprouts were investigated on a laboratory scale. Mungbean was separately imbibed in 500 and 1,000 ppm chitosan solutions for 7 hrs followed by sprinkling with distilled water, and the other mungbean was also soaked in 500 ppm chitosan solution followed by sprinkling with 500 ppm chitosan solution, and then kept at 25±1℃ for 5 days. The growth characteristics such as whole length, hypocotyl length and thickness, root length and hair, and sprout yield were maintained and increased in the chitosan-imbibed mungbean. As mungbean grew, the proximate components such as carbohydrate were almost catabolized in the chitosan-imbibed mungbean sprouts during germination. The growth rate of sprouts expressed as whole length per day was comparatively higher in the chitosan-imbibed mungbean. One of the important enzyme during germination, α-amylase, increased its activity until the 4th day and thereafter slowly decreased except 500 ppm chitosan-sprinkled mungbean sprouts showing the lower response in its activity. Consequenctly, when mungbean imbibed in chitosan solution was cultivated, the chemical composition of the resultant sprouts did not change but their growing characteristics and sporut yield were enhanced as compared with others. Therefore, chitosan treatment during the imbibition of mungbean is potential to activate the growth of mungbean but decrease it when sprinkled with chitosan solution.

In order to develop the functional muffin prepared with different levels of sprouted brown rice flour (SBRF), the mixing conditions of SBRF, butter and water were optimized by response surface methodology(RSM), using central composite design with 3 variables and 5 levels. The result of three-dimensional plot was showed that decrease of SBRF content increased the volume, maximum length, crumb grain, moistness and overall quality of muffin. The overall quality of the functional muffin was maximized under the preparing condition of 31.49 g SBRF(15% of flour used), 85.36 g butter, and 123.86 g water. Moreover, the optimum conditions for preparing muffin were as follow : 29.95 g, 81,24 g, 120.45 g for volume ; 23.67 g, 88.18 g, 118.24 g for maximum length ; 38.44 g, 63.38 g, 117.26 g for flavor ; 29.86 g, 93.04 g, 126.42 g for taste ; and 55.43 g, 94.40 g, 133.61 g for moistness. The range of optimum preparing conditions for the functional muffin in consideration of the physical and sensory characteristics were shown to the 30~40 g as SBRF, 80~90 g as butter, and 120~130 g as water.

The purpose of this study was to analyze the problems arising from the actual conditions of the Foodbank, and to implement the HACCP system as a solution in terms of increasing the safety of donated food within the Foodbank. In order to apply HACCP system, the entire Foodbank working process such as preparation, collection, transportation, division, and distribution was considered and analyzed to decide the application point for CCPs. Donated foods mainly consisted of processed foods, raw materials, lunch boxes, and cooked foods from mass catering establishments, which dominated over the others in terms of quantity. Cooked foods were divided into three groups based on menu-types and processing methods. Temperature, pH, and aw were measured on cooked foods, and Total Plate Count, Coliforms, E. coli, Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, and E. coli O157:H7 were conducted in order to apply a HACCP plan. Form these experiments, temperature, pH, and aw of donated food were likely contributed to microbial growth. Donated foods before HACCP implementation showed high numbers in terms of total plate count and Coliforms, both well over the acceptable standard levels. By setting the CCPs on maintenance of donated food below 10℃ and using a 75 ℃ reheating method, microbiological hazard levels were able to be controlled and lowered. From these results, it is concluded that in order to guarantee food safety, foods donated to the Foodbank must not only maintain a reasonable level of initial microbiological growth, but also must be handled properly through time and temperature controls within the Foodbank system. Furthermore, in terms of implementing the HACCP plan within the Foodbank management structure, basic food safety and sanitation measures, such as reheating facilities and various cold chain systmes such as refrigerated vehicle for food transportation are importantly needed. The training and education of Foodbank personnel and management in areas such as awareness of hygiene and safe food handling and practice are also required and necessary.

Mental illness such as schizophrenia, bipolar disorder and depression have shown high prevalence of obesity. According to the previous studies, nutrition education has therapeutic effects on patients, however mentally ill patients rarely have opportunities of long term nutrition education. In this study, nutrition education based on the social cognitive theory was conducted. Patients with mental illness received education program once a month during 18 months in a day hospital. Fifteen patients were included and divided into two groups according to the attendance rate. Results showed that the group attended the education more than 10 times showed weight loss, while the group less than 10 times showed weight gain. Five long-term hospitalized patients gained weight during one year prior to the nutrition education, but showed weight loss during one year with the nutrition education. Regardless of the number of attendance, the group of BMI≥30kg/m2 showed weight loss. Although this study has several limitations and did not obtain a statistically significant results, it confirmed the necessity of providing clinical nutrition services including nutrition education for mentally ill patients.

연구 배경 : 급성 신부전은 술 후 발생할 수 있는 합병증 중에서 사망률은 큰 영향을 줄 수 있으므로 이 연구를 통해 위험인자를 알아보려고 한다. 재료 및 방법 : 2004년 1월부터 2006년 12월까지 3년간 영남대학교 의과대학 부속병원에서 대장 수술을 받은 570명의 환자들을 대상으로 하였다. 환자들의 성별과 연령, 미국 마취과학회 신체등급, 동반질환, 수술의 종류, 응급수술의 여부, 수술 시간, 재수술의 여부, 술 중의 투약 상황, 술 후에 자가 통증 조절기에 사용한 약제, 술 중에 저혈압의 유무, 수혈 여부, 술 후 기계적 환기를 시행한 경우를 비교하였다. 결과 : 비교 결과에서 성별과 수술의 종류, 응급 수술의 여부, 개복여부 등에는 유의한 차이를 보이지 않았다. 반면 환자의 나이와 수술 시간, 재수술의 여부, 술중에 이뇨제 등을 사용한 경우, 술 중에 저혈압의 유무, 술 후에 기계적 환기를 시행한 경우 등에는 유의한 차이를 보였다. 결론 : 이상의 결과로 급성신부전의 원인은 어느 한 가지라고 하기 보다는 위험인자에 얼마나 노출되어 있는가가 결정하는 것 같고, 그 원인들이 모여서 상승효과를 내는 것 같다. 그러므로 수술 전부터 많은 위험에 노출된 환자는 술 중 더 적극적인 감시를 시행하여 수술 후의 합병증 발생을 줄이는 노력을 기울여야 하겠다. Background : Acute renal failure is one of the leading causes of postoperative morbidity and mortality. The purpose of this study was to determine the risk factors that are associated with acute renal failure after colorectal surgery. Materials and Methods : Five hundred seventy patients who operated colorectal surgery at the Yeungnam University Medical Center over three years from 2004 to 2006 were enrolled in this study. The effects of gender, age, ASA classification, concomitant disease, surgery type and duration, reoperation, urogenital manipulation, medication, hypotension, hypovolemia, transfusion, and postoperative ventilatory care on the occurrence of acute renal failure after colorectal surgery were studied. Results : The major risk factors of acute renal failure after colorectal surgery were age of patients (P=0.003), ASA classification (P<0.001), concomitant disease (P<0.001), duration of the time surgery (P=0.034), reoperation (P=0.001), use of intraoperative diuretics (P=0.005), use of postoperative diuretics (P<0.001), intraoperative hypotension (P=0.018), intraoperative transfusion (P<0.001), postoperative transfusion (P<0.001), and postoperative ventilatory care (P=0.001). Conclusion : Multiple factors cause synergistic effects on the development of acute renal failure after colorectal surgery. Therefore, efforts to reduce the risk factors associated with acute renal failure are needed. In addition, intensive postoperative care should be provided to all patients.
