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.

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.

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.

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.

오이와 고추의 안전성에 영향을 미치는 위해요소 분석의 기초자료로 활용하기 위해 오이와 고추 재배지에서 총 72점의 시료를 채취하여 미생물학적(위생지표세균, 병원성미생물, 곰팡이) 위해요소와 화학적(중금속, 잔류농약) 위해요소를 조사하였다. 미생물학적 위해요소 중 위생지표세균과 곰팡이는 오이 재배지에서 ND-7.2와 ND-4.8 log CFU/g (g, mL, hand, or 100 cm²) 범위로 검출되었고, 고추 재배지에서는 ND-6.8와 0.4-5.3 log CFU/g (g,mL, hand, or 100 cm²) 범위로 검출되었다. 특히 대장균군은 고추재배지의 토양에서 최대 5.6 log CFU/g까지 검출되었다. 병원성 미생물은 S. aureus는 오이 농장의 장갑에서만 1.4 log CFU/100 cm²으로 검출되었고, B. cereus는 대부분의 시료에서 ND-4.8 log CFU/g (g, mL, hand, or 100 cm²) 범위로 검출되었다. L. monocytogenes, E. coli O157:H7 및 Salmonella spp.는 검출되지 않았다. 화학적 위해요소에 해당하는 중금속은 Zn, Cu, Ni, Pb 및 Hg이 국내 허용기준치 이하로 검출되었고, 잔류농약의 경우 오이에서는 모든 성분이 불검출 되었으나 고추에서 hexaconazole 성분이 0.016 mg/kg (기준치: 0.3 mg/kg)으로 검출되었다. To analyze the hazards associated with cucumber and hot pepper cultivation areas, a total of 72 samples were obtained and tested to detect the presence of biological (sanitary indicative, pathogenic bacteria and fungi) and chemical hazards (heavy metals and pesticide residues). The levels of sanitary indicative bacteria (aerobic plate counts and coliforms) and fungi were ND-7.2 and ND-4.8 log CFU/(g, mL, hand, or 100 cm²) in cucumber cultivation areas, and ND-6.8 and 0.4-5.3 log CFU/(g, mL, hand, or 100 cm²) in hot pepper cultivation areas. More specifically, the soil of hot pepper cultivation areas was contaminated with coliforms at a maximum level of 5.6 log CFU/g. Staphylococcus aureus was detected only in glove samples at a level of 1.4 log CFU/100 cm² and Bacillus cereus was detected in the majority of samples at a level of ND-4.8 log CFU/(g, mL, hand, or 100 cm²). Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella spp. were not detected. Heavy metal (Zn, Cu, Ni, Pb, and Hg) chemical hazards were detected at levels lower than the regulation limit. Residual insecticides were not detected in cucumbers; however, hexaconazole was detected at a level of 0.016 mg/kg (maximum residue limit: 0.3 mg/kg) in hot peppers.

본 연구에서는 딸기의 수확단계에서의 생물학적 위해요소를 조사하고 그 결과를 딸기 GAP 모델의 개발을 위한 기초자료로 제공하기 위해 수행하였다. 경남 서부에 소재한 딸기 농장 6곳(토경재배 3곳, 양액재배 3곳)에서 총 216점의 시료를 수집하여 위생지표세균, 병원성 미생물, 그리고 곰팡이에 대해 분석하였다. 일반세균과 대장균군의 경우 토경재배 농장에서는 각각 1.0-6.9와 0.4-4.6 log CFU/g(leaf, mL, hand or 100 ㎠) 수준으로, 양액재배 농장에서는 각각 0.8-4.9 log와 0.2-2.6 log CFU/g(leaf, mL, hand or 100 ㎠)수준으로 검출되었고 대장균은 모든 시료에서 검출되지 않았다. 병원성미생물은 S. aureus가 작업자의 손에서 최대 3.3 log CFU/hand 수준으로 검출되었고, B. cereus가 토양과 작물, 개인위생에서 0.4-4.1 log CFU/g(hand or 100 cm2) 범위로 검출되었으며, L. monocytogenes, E. coli O157:H7 및 Salmonella spp.는 검출되지 않았다. 곰팡이는 토경재배 농장과 양액재배 농장 각각 1.0-5.2와 0.2-4.4 log CFU/g(leaf, mL, hand or 100 ㎠) 수준으로 검출되었다. This study assessed hazards at the harvest stage of strawberry farms which may cause risk to humans. A total of 216 samples were collected from 6 strawberry farms (soil culture farms: A, B, C; nutriculture farms: D, E, F) located in Western Gyeongnam. The collected samples were subjected for sanitary indicator bacteria (aerobic plate count, coliforms and Escherichia coli), major foodborne pathogens (E. coli O157:H7, Listeria monocytogenes, Salmonella spp., Staphylococcus aureus and Bacillus cereus), and fungi. The levels of APC and coliform in the soil culture farms were 1.0-6.9 and 0.4-4.6 log CFU/g (leaf, mL, hand or 100 cm2), respectively. The samples obtained from the nutriculture farms were contaminated with the levels of 0.8-4.9, and 0.2-2.6 log CFU/g (leaf, mL, hand or 100 ㎠) of APC and coliform. However, E. coli was not detected in any samples. In major foodborne pathogens, S. aureus was detected at the level of ≤3.3 log CFU/hand in workers’ hand samples and B. cereus was detected at the levels of 0.4-4.1 log CFU/g (hand or 100 ㎠) in soil, plants and workers’ hygiene. L. monocytogenes, E. coli O157:H7 and Salmonella spp. were not detected. Fungi were detected at the levels of 1.0-5.2 and 0.2-4.4 log CFU/g (leaf, mL, hand or 100 ㎠) in soil culture and nutriculture farms, respectively.
