Chlamydia trachomatis has now shown that this interesting intracellular parasite is a cause of nongonococcal urethritis, infantile pneumonia, pelvic inflammatory disease and epididymitis, in addition to lymphogranuloma venerum and inclusion conjunctivitis. There are several diagnostic methods for C. trachomatis, but the method using monoclonal antibody is the most sensitive and specific. The hybride cell were prepared by fusion of myeloma cell($P_3X_{63}\;Ag_8{\cdot}V_{653}$) of mouse and lymphocyte of mouse(BALB/c) that were immunized with formalin killed C. trachomatis serotype D. The cell mixtures after fusion were dispensed into 640 wells of the 96 well culture plates and continuously cultured in HAT medium for 2 weeks. The supernatants of culture media in 83(13%) wells were reacted with C. trachomatis, which were determined by enzyme-linked immunosorbent assay in 96 well microplate. The clones that secreted antibody to C. trachomatis were cloned by limiting dilution. Only six monoclones secreted antibody to C. trachomatis. The antibody titer of ascitic fluid that collected from same BALB/c mice bearing hybridoma cells was above 1:100,000. These monoclonal antibodies that were IgG reacted with elementary and reticulate bodies of all serotypes(Ba, D, E, F, G, H, J and LGV type-I) using ELISA and indirect immunofluorescence stain, but there were no cross reaction with other bacteria(coagulase negative Staphylococcus, Proteus and E. coli). We concluded these six monoclones secreted the same monoclonal antibody to C. trachomatis. The sensitivity and specificity of the monoclonal antibody compared with Microtrak(confirmatory test of C. trachomatis, Syva) was 100%, respectively.

목 적 : 지난 30년간의 연구로 병인론에 관한 중요한 정보들이 축적되어왔다. 하지만 아직도 완전히 이해된 것은 아니며, 연령이나 성별, 임상증상의 발현율에 대한 다양한 연구 결과들이 발표되고 있다. 이에 본 연구에서는 저자들이 경험한 125명의 HS 자반증 환아들의 임상적 특징을 알아보고, 이전의 다른 논문의 연구결과들과 비교해 보고자 하였다. 방 법 : 환아는 1992년 3월부터 2000년 4월까지 충북대학교병원 소아과에 방문하여 특징적인 자반과 복통이나 관절염 등의 임상증상을 통하여 HS 자반증으로 진단된 환아를 대상으로 하였으며 입원하거나 외래에 내원한 경우 모두 포함하였다. 결 과 : HS 자반증으로 진단된 환아는 남자 87명 여자 38명으로 구성되었고, 연령은 1세에서 14세에 걸쳐 분포하고 있었다. 계절에 따른 변화로 3월부터 5월까지 모두 56명(44.8%), 10월에서 12월까지 51명(32.8%)으로 나타났다. 자반은 모든 환아에서 관찰되었다. 복통은 88명(70.4%)에서 관찰되었으며, 위장관 출혈은 18명(14.4%)에서 관찰되었고, 관절염은 67명(53.6%)에서 관찰되었다. 모두 125명의 환아 중 신장 침범이 있는 환아는 48명으로 HS 자반증 환아 중 38.4%였다. 부고환염은 남아 87명 중 15명(17.2%)에서 발생하였다. 자반이 발생한 후 나타난 동반 증상 중 2명(1.6%)의 환아에서 경련이 발생하였으나 항경련제 치료없이 호전되었고, 두통이 11명(8.8%)의 환아에서 발생하였다. 결 론 : 결론적으로, HS 자반증은 전신적인 혈관염이기 때문에 자반 이외의 증상들이 선행할 수 있으며, 소아에서 설명할 수 없는 복통이나 관절염, 음낭 증상 등이 발생할 경우, 자반이 출현하기 전이라도 임상 각과에서 HS 자반증에 대해 의심해보고, 소아 신장 전문의와의 협진이 필요할 것으로 사료된다.

Objectives : To describe the characteristics of a mumps epidemic in Cheju-do, 1998 and to identify the risk factors associated with mumps infection. Methods : To estimate attack rate, previously collected data from the Nationally Notifiable Communicable Disease Reporting System and School Health Reporting System, temporarily administered by Division of Education. as well as additional surveillance data were used. In order to identify the clinical characteristics and risk factors associated with mumps, we conducted a questionnaire survey in 17 schools (9 elementary, 4 middle, and 4 high schools) among a population that included healthy students. Results : From March 3 to August 31, 2,195 cases of mumps were identified, and patients under 20 years of age accounted for 2,162 cases (attack rate 13.2, 95% CI 12.6-13.7/1,000). The attack rate for the population under 20 years of age was the highest in Nam county (44.7/1,000), nod in the 7-12 years old sub-group(>20.0/1,000). There was no sexual difference. 80.5% and 59.7% of patients presented periauricular and submandibular swelling respectively. Aseptic meningitis was a complication in 2.9% of cases, orchitis in 1.3%, epididymitis in 0.9% and oophoritis in 0.6% respectively. The overall MMR vaccination rate was 59.1% and it decreased in accordance with increasing age. In students aged 10 years old or below, household contact and MMR vaccination status was significantly associated with infection, and only among students with household contact, the risk of one dose MMR(OR=10.22, 95% CI 2.92-35.78) and non-vaccination (OR=11.62, 95% CI 1.96-68.96) was significantly greater when. compared with that of two dose vaccination. Among students aged 11 years old or above, household contact history was significantly associated and MMR vaccination status was not associated. Conclusions : Low vaccination rate and vaccine failure were thought to predispose the population for this large outbreak. To prevent sustained mumps outbreaks, a second MMR vaccination should be encouraged and catch up vaccinations should be given to elderly children who remain susceptible.
