School children were examined for the presence of Enterobius vermicularis egg by perianal swab method at 52nd and 41st primary school between September 30, 1998 and October 7, 1998 in Kyrgyzstan, 281 children examined, 80(28.5%) were found to be positive for E. vermicularis egg. The egg positive rate of boys and girls were 41(29%) and 39(28%), respectively. Through this survey, we found that E. vericularis infection is still prevalent among children in Kyrgyzstan.

In an attempt to determine the prevalence of pinworm infection, the egg positive rate of Enterobius vermicularis was examined using the adhesive cello-tape anal swab method in 1,512 preschool children sampled from a total of 20 kindergartens in Cheongju city, in November to December of 2004 (951 children from 13 kindergartens) and September to October of 2005 (561 from 7 kindergartens). The overall egg positive rate was found to be 7.9% (119/1,512); 9.3% (73/784) for boys and 6.3% (46/728) for girls, respectively. The 5-year age group evidenced the highest egg positive rate (10.9%, 47/430) among the examined age groups. As compared to those reported from previous works (ranged from 9.2 to 26.1 %), the prevalence of E. vermicularis in the Cheongju city area is relatively low.

A survey of the infection rate of Enterobius vermicularis among students in 4 primary schools located in Gangwon-do (Province) was done from May to .Tune 2001. Among the 398 examinees,39 (9.8%) were infected with E. vermicularis demonstrated by the adhesive cellotape anal swab method. The infection rates ranged from 8.3% to 11.8% among the four schools. The infection rate of males and females was 10.7% and 7.7% respectively. The first grade students showed the highest infection rate, 28.7%. The confirmed cases were treated with albendazole three times at an interval of 15 days. We were able to confirm that E. vermicularis infection is still prevalent among students in Gangwon-do , Korea.

Surface swab samples from beef (188), pork (240) and chicken (95) carcasses were collected from slaughterhouse in Kangwon and Kyunggi areas from March through July 1996. The samples were examined on the level of E. coli biotype I relevant to fecal contamination due to unsanitary processing control and the existence of verocytotoxin-producing E. coli (VTEC). E. coli biotype I were confirmed from 38.8% of beef, 40.0% of pork, and 69.5% of chicken carcasses. Little variation was noted among three sampling points; rump, flank and neck of beef, ham, belly and jowls of pork. coli O157:H7 was only confirmed from 2 of 188 beef carcasses. E. coli biotype I. All the isolated E. coli O157 showed positive for vero cell cytotoxicity test. Isolation rate of E. coli O157 in summer was higher than in spring. In case of pork and chicken carcasses, E. coli O157 was isolated in summer only.

심한 항문 주위 가려움증이 있는 15개월 된 소아(인천 거주)로부터 과수태 요충 1마리를 항문 주위 도말법으로 회수하였다. 충체는 길이가 7.8 mm이고 폭이 0.5 mm였으며. 두익(73보) 자궁내 충란. 뽀족한 로리 등 요충 자충의 특이한 형태학적인 특징을 가지고 있었다. 그러나 이 충체는 과수태한 충체로서 자궁이 충체 전단에서부터 후단까지 길게 확장되어 있었으며. 충체 길이 의 약 99%까지 수많은 충란으로 가득 차 있고 다른 기관은 관찰하기 어려운 특이한 충체이었다.

Ion beam Sputtering (IBS)를 이용한 물질 표면의 pattern 형성은 물리적 변수 조절로 손쉽게 nano structure의 크기와 형태를 조절할 수 있어 관심을 받고 있다. 본 연구발표에서는 massless Dirac Fermion behavior로 인한 highly carrier mobility와 같은 특성으로 인해 차세대 device material로 각광받고 있는 Graphene의 layered compound (층상구조) 형태인 HOPG (Highly Ordered Pyrolysis Graphite)에 IBS (Ion beam Sputtering)를 이용해 nano structure가 형성 가능함을 보이고 그 특징에 대해 소개하려 한다. HOPG(0001)를 Sputter 했을 때, 표면에 잘 정렬된 nano ripple pattern이 형성 가능함을 확인하였으며 sputter하는 시간을 변화하면 약 10 nm에서 80 nm까지 wavelength를 조절할 수 있다. 또한 이전의 IBS를 이용한 연구들에서 확인할 수 있는 다른 물질의 곧게 뻗은 nano ripple과는 다르게 ripple의 끝에 nano swab이 생기는 것을 AFM (Atomic Force Microscope)으로 확인할 수 있었다. 이러한 Graphite에서만 나타나는 Sputter에 의한 표면의 변화의 원인을 규명하고자 Sputter가 지속됨에 따라 나타나는 mopology의 roughness와 wavelength의 시간에 따른 dynamic scaling behavior를 확인하였고 그 얼개를 알기 위해 simulation을 수행 하였다.

A 9-year-old male Maltese with foamy nasal discharge, respiratory distress, and sneezing followed by epistaxis was presented to the Veterinary Medical Teaching Hospital of Seoul National University. Radiography showed no significant findings from an open mouth view. Rhinoscopy also did not find any remarkable lesions in the nasal cavity. But when vigorously swabbing the nasal cavity, numerous cells having round nuclei, coarse reticular chromatin, one large nucleolus and distinct cytoplasmic vacuoles, which is typical for canine transmissible venereal tumor cells were collected. We thoroughly searched for any primary transmissible venereal tumor at the other areas of the body other than the nasal cavity, but found none. The patient responded well to vincristine, and the clinical signs resolved with no respiratory distress, sneezing or epistaxis.

The egg Positive rate of Enterobius vernicularis was investigated among students of a primary school and a kindergarten located in the rural area of Tangjin-gun, Chungchongnam-do in December, 1998. Of the 189 examinees, 28 (14.8%) were found to be infected with E. vermicularis by the adhesive cellotape anal swab method . The infection rates ranged from 4.2% to 26.1% among school children, and the highest rate was observed in children attending kindergarten. Three months after treatment with albendazole, four (14.3%) out of 28 infected children still remained infected with E. vermicularis. Through this survey, we were able to determine that E. vemicularis infection is still prevalent among children in rural areas of Korea.

A 3-year-old, captive female river cooter was presented with a 4-day history of progressive unilateral swelling of the right side of the head, lethargy, and anorexia. History, physical examination, and radiographic examination revealed an aural abscess. After administration of antibiotics and supportive care, surgical intervention was performed. Swab samples were collected from the tympanic cavity during surgery for cytology and antimicrobial susceptibility testing. Molecular analyses of 16S ribosomal RNA gene sequences identified Citrobacter spp. and Morganella morganii. The patient was treated with ciprofloxacin and meloxicam and recovered after 2 months. This report describes the successful correction of a unilateral aural abscess that responded well to surgical intervention and a properly selected antibiotic.

A Miniature Schnauzer presented with bilateral mucopurulent nasal discharge and sneezing. Computed tomography of the skull revealed exudates in the nasal cavity and frontal gyrus. Nasal swab cytology showed features of an epithelial-origin tumor. Histopathologic evaluation of the biopsy specimen revealed irregular proliferation of epithelial cells and necrotized tissue. Positive immunohistochemical staining confirmed the epithelial origin of the cells. The dog was diagnosed with nasal carcinoma and was treated with a chemotherapy protocol of carboplatin and piroxicam. This report confirms the effectiveness of combination chemotherapy only without radiotherapy in a dog with nasal carcinoma and provides a guideline for providing alternative treatment.
