심원보,최희인,Shim Won-Bo,Choi Hee-in 한국임상수의학회 1989 한국임상수의학회지 Vol.6 No.2
In order to study the effects of neomycin sulfate on the kidney of Korean black goats after dosing at 36mg/kg(A group) or 18mg/kg of body weight (B group) twice a day, serum chemical values(BUN, SCr), urinary enzyme(GGT) excretion and urinary analysis were checked and renal lesions were observed by light microscope. The proteinuria and granular casts were observed on the 5-6th day and 7th day of treatment with neomycin respectively in the A group. While these changes were observed on the 4th day and the 6th day respectively in one goat of the B group. Urinary GGT excretion began to increase from the 9th day and reached to maximum concentration on the 15th day of treatment with neomycin in the A group. Thereafter, GGT excretion began to decrease and reach to normal level on the 21th day. But GGT excretion increased on the 9th day in only one goat of the B group. Concentrations of BUN and SCr increased on the 12th day in the A group and in one goat of B group. The kidneys were swollen gross pathologically and the renal tubular epithelial cell changes were noticed histologically in the A group and in one goat of the B group. These changes were included degeneration with hyaline droplet formation, flattened epithelial cells and necrotic epithelium. Granular casts were showed in many tubular lumens. Prfesent results indicated that nephrotoxicosis would not occured in Korean black goats dosing with neomycin sulfate less that 36mg/kg of body weight a day.
골유착 치과 임플란트를 이용한 상악 무치악부 치료의 예후에 관한 임상적 평가

The use of osseointegrated implant has been reported that is an acceptable procedure for the restoration of totally or partially edentulous patient and that offers good predictability of long term success. It is difficult to get high success rate in edentulous maxillae with inadequate bony quality and quantity, and anatomic limitations such as pneumatic maxillary sinus and nasal floor. The various trials such as sinus lifting, bone grafting, guided bone regeneration, trabecular condensation with osteotome, and the use of wide-diameter implant have been introduced to solve these problems. This study was undertaken to assess the evaluation of clinical prognosis of the implant restorations with these various implantation techniques in the maxillary edentulous area. One hundred eight patients were treated with a total of 386 endosseous implants from March 1994 to January 1998 at Dept. of Dentistry, Korea Veterans Hospital in Seoul Korea. The various techniques for implantation in the edentulous maxillae were supplied to overcome the limitations of implant fixation. These techniques consist of sinus lifting, guided bone regeneration, onlay bone grafting, and osteotome trabecular condensation technique. The total success rate of implant restoration of this study was 93% in the maxillae. The success rate of implant restorations with conventional technique was 94.6%, with osteotome trabecular condensation technique was 94.1%, with guided bone regeneration technique was 93.3%, with bone grafting technique was 92.9%, with sinus lifting technique was 83.8%. The success rate on the maxillary anterior area was 95.2% and that on the posterior area was 91.9%. The failures were associated not only with surgical installation techniques but also bony quality and quantity, characteristics of implant, and stress distribution when in function.

Objectives: The aim of this study was to investigate the microbial contamination levels in elevators in apartment buildings and to provide information on such microbial contamination. Methods: A total of 144 samples, including from the exterior buttons, interior buttons, elevator handrails, walls, ventilators and airborne bacteria were collected in the morning and afternoon from July to August 2013 for six different elevators. The samples were used to detect sanitary indicator bacteria (total bacteria, coliform, and Escherichia coli), pathogenic bacteria (E. coli O157, L. monocytogenes, Salmonella spp., B. cereus, S. aureus) and fungi. Results: Contamination levels of total bacteria were 0.3-3.8 and 0.0-2.4 log CFU/100 $cm^2$ in the morning and afternoon, respectively. In the case of coliform bacteria, the levels were 0.0-3.7 log CFU/100 $cm^2$ in the morning and 0.0-0.3 log CFU/100 $cm^2$ in the afternoon. However, E. coli was not detected among all samples. Bacillus cereus, pathogenic bacteria, was only detected in 13 (11%) among 144 samples. E. coli O157, L. monocytogenes, Salmonella spp. and S. aureus were not detected among all samples. Comparing the samples collected in the morning and afternoon, we could confirm that the samples in the afternoon were cleaner. Conclusions: This study indicates that the samples in the afternoon were cleaner because these samples were collected following routine cleaning. Also, the levels of contamination in the elevators were low and the sanitary conditions were comparatively well-managed. Therefore it is deemed necessary for elevators be cleaned regularly to provide good conditions for people using elevators.
서부경남 재래시장을 대상으로한 유전자 재조합 대두의 모니터링

The objective of this study was monitoring of genetically modified soybean by PCR and ELISA. We collected 60 soybean samples from the open markets located in Western Gyeongnam (Sacheon, Hamyang, Hadong, Sanchung, Uiryung, Geochang, and Hapcheon). A total of 60 soybeans was examined and 14 genetical modified soybean (GMS) were detected by PCR. The GMS rate of selling soybean in Uiryung, Hadong, Sacheon, and Hapcheon was 50.0%, 37.5%, 33.3% and 25%, respectively. The 7 of 14 GMSs were positive by ELISA and most of positive samples were below 3% GMS but 1 (Uiryung 1) of the positive samples was over the 3% which is maximum permit limit in Korea. These results mean that merchants of open market did not express for selling soybean mixed with GMS, so consumers did not recognize GMO. Therefore, we thought that education of GMO for merchant of open market need to recognize about GMO maximum permit limit.
