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.

The status of Pinworm (Enterobius vermicularis) egg positive rate of Primary school children in Geoje island was investigated by using adhesive cellotape anal swap method, in September, 2002. Total egg positive rates of E. vermicularis were 9.8% (74/754) and those of male and female were 10.8% and 8.7%, respectively. Among three schools examined, Myeongsa primary school showed the highest egg positive rate (12.6%) followed by Yeoncho [9.8% (26/266)] and Geoje［9.1% (35/385)]. As for the age groups, the 2nd grade had the highest egg positive rate (15.3%), whereas the 5th grade showed the lowest egg positive rate (2.6%). The above result led us to confirm that the egg positive rates of E. vermicularis in primary school children in Geoje island were not significantly different from the those in the whole country including urban and rural areas, showing more than 10%.

The egg Positive rate of Enterobius vermicularis and Clonorchis sinensis of school children in the rural area was studied in Hamyang-gun, Gyeongsangnam-do in Korea. Cellotape anal swab and formalin ether concentration methods were performed one time to 720 Primary school children. The total egg Positive rate of E. vermicularis was 12.6% in two schools (Baekjeon and Wiseong). In the Baekjeon and Wiseong primary school, the egg Positive rate of E. vermicularis was 4.6% and 13.4%, respectively Pinworm egg Positive rate was 17.6% in the lower grades (1st, 2nd and 3rd), and 7.7% in higher grades (4th, 5th and 6th). The total egg Positive rate of male and female was 12.6% and 12.7%, respectively. The egg Positive rate of C. sinensis of Baekjeon and Wiseong Primary school was 1.5% and 0.46%, respectively The total e99 Positive rate of C. sinesis was 0.56%. This survey showed that continuous education and chemotherapy is necessary to treat and prevent reinfection of E. vermicularis. In the case of C. sinensis, health education for school children is recommended to prevent potential infection of adolescents.

The prevalence rate of Enterobius vermicularis eggs was investigated among preschool children located in the area of Iksan, Jeonbuk, during the period from March to July, 2005. Of the 1,082 children examined 78(7.2%) were found to be positive for E. vermicularis egg by the adhesive cellotape anal swab method. The egg positive rate of male and female were 6.7% and 7.8%, respectively. The positive rates range from 5.1% to 8.7% among preschool children, and the highest egg positive rate was observed in the 7 year old age group. Through this survey, it was determined that the E. vermicularis infection is still prevalent among children in Jeonbuk, Korea.

The aim of the present study was to find out the number of students with enterobiasis and/or taeniasis in primary schools of Sivas. Among the 2,029 students in 6 primary schools, $316(15.6\%)$ were positive to Enterobius vermicularis eggs and $32(1.6\%)$ were positive to Taenia spp. eggs by the cellophane tape method. The egg positive rates of E. vermicularis and Taenia spp. ranged from $9.4\%\;to\;27.2\%\;and\;from\;0.8\%\;to\; 2.6\%$ respectively among six schools. The egg positive rate of E. vermicularis was found to be significantly different among these schools $(X^2=31.96,\;P<0.05)$, whereas there was no significant difference between the schools for Taenia spp. $(X^2=4.37;\;P>0.05)$. The rate $(18.7\%)$ of E. vermicularis in the urban slum regions was higher than the rate $(11.5\%)$ in the urban central regions $(X^2=19.20\;P<0.05)$. Above results demonstrate that the egg positive rate of E. vermicularis and Taenia spp. was still prevalent among primary school children.

Pre-school children were examined for the presence of Enterobius vermicularis egg by perianal swab method. We visited 67 nurseries and 25 kindergartens between January, 1999 and April, 1999 in Chunchon, Korea. Of the 4,711 children examined, 434 (9.2%) were found to be positive for E. vermicularis egg. The egg positive rates of boys and girls were 10.1% and 8.1%, respectively. The rates were 7.8% in kindergartens and 9.7% in nurseries. Positive rate of 50 institutions was less than 10%. Rate in 35 institutions was from 10% to less than 20%. Rate in 7 institutions was equal to or over 20%. Out of 1,113 children examined twice, 28 (2.5%) children were positive consecutively, 53 (4.8%) were positive with negative conversion, 47 (4.2%) were negative with positive conversion, and 985 (88.5%) were consecutively negative. It means that in the low endemic area of enterobiasis with around 10% positive rate, the two consecutive examinations may increase the egg detection rate of 4.2-4.8%. The small number of consecutive egg positive children also suggests that the worm burden of the positive children might be low. Since the egg positive rate of that a9e group in this City increased from 1.85% (1997), and 3.0% (1998), the more intensive regular control should be executed.

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.

목 적 : 최근에 생활 환경과 식생활의 수준 등이 향상되고 농경작의 현대화가 이루어지면 서 토양 매개성 기생충 질환(회충, 편충, 구충 등)은 크게 감소되었으나 사람이 유일한 숙주 인 요충의 감염은 쉽게 전파될 뿐만 아니라 재감염이 잘 되고 특히 소아에서 많이 감염된다 고 알려져 있다. 국내에서의 요충 감염율은 검사 시기, 대상, 지역에 따라서 차이는 있으나 1960~1980년대나 최근에 있어서나 높은 감염율을 나타내고 있는 실정이다. 따라서 본 연구는 마산, 창원과 인근 농촌지역에서 요충 감염율을 조사하고 치료에 대한 효과를 보기 위하여 실시하였다. 방 법 : 97년 11월 4째주와 12월 1번째 주에 마산시에 소재한 초등학교 1곳, 어린이집 2곳, 창원시에 소재 개인 소아과 의원1곳, 창녕군 남지읍에 소재한 초등학교 1곳을 선정하여 보호자들에게 설문지와 안내문, 검체 채취용 슬라이드를 나누어 주어 이른 아침, 첫 대변을 보기 전에 항문주위도말법(adhesive cellotape anal swab)으로 검체를 채취하도록 하였다. 수집한 검체는 경북대학교 의과대학 기생충학교실로 보내져 광학 현미경으로 충란의 유무를 확인하였다. 결 과 : 1) 전체 대상 아동 644명 중 17.7%인 114명에서 요충란이 발견되었으며 남녀의 비는 1:1.1로 나타났다. 2) 연령별 분포에서는 학동기전 아동이 145명중 29.0%인 42명, 학동기 아동은 499명중 14.4%인 72명에서 요충란이 발견되었으며 학동기전 아동들의 충란 검출율이 학동기 아동들 보다 통계적으로 의미 있게 높았다(p<0.05). 3) 도시와 농촌의 초등학교에서 감염율은 각각 15.2%, 13.7%로 나타나 차이가 없는 것으 로 나타났으며(p>0.05) 3학년 이하의 저학년일수록 감염율은 높았다(p<0.05). 4) 충란 검출율이 높았던 마산시 소재 한 어린이집에 수용되어 있는 아동과 가족, 종사자들에게 flubendazole 100mg을 3주 간격으로 2회 먹인 후 검사한 결과 치료전 41.0%의 검출 율을 보이다가 치료 후 6.0%로 떨어졌다. 결 론 : 요충의 감염 경로 및 전염력을 감안하면 어린이 집단에서 요충의 감염율은 상당히 높을 것이라고 사료되며 따라서 조속한 시일내에 요충 감염의 조사와 집단 치료가 필요할 것이라고 생각된다.

There is often the risk of confusing pollen grains with helminth eggs from archaeological sites. Thousands to millions of pollen grains can be recovered from archaeological burial sediments that represent past ritual, medication and environment. Some pollen grain types can be similar to parasite eggs. Such a confusion is represented by the diagnosis of enterobiasis in ancient Iran. The authors of this study confused a joint-pine (Ephedra spp.) pollen grain with a pinworm egg. This paper describes the specific Ephedra pollen morphology that can be confused with pinworm eggs.
