  • The infectivity of metacestodes of Asian Taenia saginata, now tentatively called Taenia saginata taiwanensis, in human host was confirmed. The metacestodes used in experimental infection were collected from the livers of naturally infected domestic pigs at an abattoir in Cheongju City, Korea. The first gravid proglottid was spontaneously discharged 76 days after infection. Two worms were recovered two years later by chemotherapy. The scolex was unarmed. The number of main uterine branches, varying from 16 to 21, was similar to that of classical Taenia saginata. The liver of pigs was confirmed to be an infection source of Asian T. saginata in Korea.

  • The third human case of natural infection by Heterophvopsis continuo in Korea was found in Chinju, Kyongsangnam-do. The case was a 53-year-old mn. He used to eat raw brackish and fresh water fish. After praziquantel treatment and purgation, H. continua were collected from the diarrheal stool together with Metononimw vokognwai, Heterophves nocens and Echinostona hokense. His clinical complaints were indigestion, epigastric discomport, poor appetite and fatigue. The complaints were considered rather due to heavy M. Wokoscwci infection.

  • AI로 인해 급감한 소비를 회복시키고 소비자들을 안심시키기 위해 의료계와 식품산업계가 나섰다. 대한의사협회(이하 의협) 국민의학지식향상위원회가 20일 '조류인플루엔자 문제에 대한 심포지엄'을 개최하고 의학계, 수의학계, 보건당국 전문가들로부터 AI 인체감염을 예방하기 위한 대처방안들을 제시하였다. 조류인플루엔자(AI)가 실제 사람에게 감염될 가능성은 희박하다는 게 현재까지의 중론이지만 만약의 상황에 대비해 AI 감염요인과 예방법을 올바로 숙지해야 한다는 의견이 제기됐다.

  • 황색 포도상구균은 급성 구강 감염에 있어서의 병원균이다. 그러나 그러한 황색 포도상구균의 병원성 기전은 완전히 이해되지 않았다. 이전 실험에서 황색 포도상구균의 단백질 A와 골격근의 액틴 필라멘트는 인체 상피 세포로의 황색 포도상구균의 침입에 관여한다. 구강 내 감염에 있어서의 황색 포도상구균의 병원성 기전을 조사하기 위해 인체의 치은 섬유모 세포에 대한 침입이 연구되고 있다. 급성 구강 감염을 가진 환자로부터 분리된 ATCC 25923 황색 포도상구균과 OPT 2 황색 포도상구균의 침입은 시간(0-120분)에 의존한다는 사실을 밝혀냈다. 60분을 초과하는 배양시간은 다시 배양된 균집락수 증가를 가져왔다. 배지에 접종한 세균의 숫자가 증가할 때 (100?10,000,000 cfu/ml/well), 직선적으로 증가한다. 단백질 A가 결핍된 Wood 46 황색 포도상구균의 침입은 단백질 A가 발현된 균주(ATCC 25923과 OPT 2)의 침입보다 훨씬 낮았다. 액틴 필라멘트의 합성을 방해하는 Cytochalasin D는 인체 치은 섬유모세포로 황색 포도상구균 (ATCC 25923과 OPT 2)이 침입하는 것을 방해한다. 이러한 결과는 구강내 감염을 일으키는 황색 포도상구균의 병원성 기전이 세포내 침입에 관여하고, 황색 포도상구균 단백질 A와 골격근의 액틴 필라멘트가 인체 치은 섬유모세포로의 황색 포도상구균의 침입 조절에 관여한다는 것을 보여준다.

  • The worm development and egg laying pattern of Echinostoma hortense (Trematoda; Echinosto-matidae) were studied in albino rats and the brief clinical course was observed in human volunteers. A total of 21 rats were infected with 20~69 metacercariae each and two humans were with 7 and 27 metacercariae, which were collected from the loaches. For recovery of worms, the rats were sacrificed at irregular intervals from the 6th to 150th day after infection and the human volunteers were treated with praziquantel and purged with magnesium salt on the 26~27th day. The stools of the rats and humans were examined for the eggs. The results were as follows: 1. The worm recovery rate from the rats was not affected by the increase of infection time but varied individually; 9.1~50.0% (31.1 % in average). From humans, 14.3% and 37.0% (32.4% in average) of challenged were recovered. 2. In the rats, it was revealed that the worms rapidly grew for the first 14 days to become 7.59mm in average length and 1.17mm in average width but the growth became much slower thereafter until the 150th day; 7.95mm in length on the 21 th day, 9.04mm on the 28th day, 10.21mm on the 49th day and 12. 62mm on the 150th day. During the early stage of infection, the growth of genital organs (male or female) was expressed as sigmoid curves whereas non-genital organs (such as suckers) was simply as straight lines. 3. The prepatent period of this fluke was 10~12 days in the rats and 16~17 days in men. After the start of oviposition, the egg production by the worms remarkably increased, reached maximum on the 32~33th day, followed by decrease thereafter. The maximum value of E.P.G./worm was 390. 4. The major subjective symptoms in human volunteers were abdominal pain and diarrhea during the early stage of infection. The results show that human is as susceptible as the rats to E. hortense infection and the amount of egg production in the rats is greatly affected by the age of worms.

  • A human case of Echinostoma cinetorchii infection was found in Seoul Paik Hospital on August, 1987. Large trematode eggs, $98.9{\times}62.7{\mu\textrm{m}}$ in average size, were detected in stool examination. The eggs had a small.sired operculum and abopercular wrinkling. After treatment with praziquantel (single dose of 16.2mg/kg) and purgation with magnesium citrate, an adult fluke was collected. It was 8.0 mm long, equipped with 37 collar spines around head crown, and had only one testis just behind the Mehlis' gland. It was identified as E. cinetorchis Ando et Ozaki, 1923. The patient is an 18-year old man residing in Seoul, and was hospitalized due to nephritis. He had eaten raw meat juice of fresh water fishes such as top minnows (Orygias Satipes) and loaches, or tadpoles, which are considered possible source of this fluke infection. This is the 4th human case of E, cineterchis infection in Korea.

  • A human case of Centrocestus armatus (Heterophyidae) infection was proved by identifying an adult worm collected after treatment with praziquantel in Korea. The case is 42-year old man who resides in a rural area in Sanchung-gun, Kyeongsangnam·do. The case was concomitantly infected with Clonorchis sinensis and had the history of eating raw (reshwater fishes including Zacco platypus, which are known to be the second intermediate host of C. armatus in Korea. This is the first report of natural human infection by C. armatus in the literature.

  • 많은 사람들이 에이즈의 첫 증상하면 붉은 반점을 흔하게 떠올리게 된다. 사실 이것은 에이즈 전구 증상이 아니고 사람면역결핍바이러스(HIV)에 감염되고 8-10년간의 무증상기를 거친 후에 인체의 면역기능이 바닥까지 망가졌을 때에 생기는 카포시 육종이라는 질병이다. HIV에 감염된 후에 면역기능이 파괴되면 본래 정상인에게 병을 일으키지 않는 미생물에 의해서 감염증이 생기고(이를 기회감염이라고 함)암도 발생하게 된다. 이와 같이 HIV 감염인에게 기회감염 혹은 암 등이 발생한 상태를 에이즈라고 한다. 어떤 사람들은 HIV에 감염된 후에 에이즈가 발병하기 전까지 아무런 증상을 느끼지 못하지만 일부는 에이즈 발병 전에 여러 가지 증상들(에이즈 전구 증상)을 겪게 된다. 오늘은 HIV에 감염된 후 에이즈가 발병하기 전에 발생할 수 있는 전구 증상들에 대해 알아보고자 한다.

  • Echinostomatid eggs were found from a 21year old man, whose native village is Munkyong-gun, Kyongsangnam-do during fecal examination in October 1983. The eggs were detected again one week later concommitantly with the eggs of Clonorchis sinensis. He had no subjective symptoms related with these fluke infections. He was treated with praziquantel ($Distocide^{\circledR}$) 20 mg/kg in single dose and purgated with magnesium salt. One echinostomatid fluke and 4 adults of C. sinensis were collected from the diarrheal stools. After morphological observation, the echinostomatid fluke was identified as Echinostoma hortense Asada, 1926. This is the first record on human E. hortense infection in Korea.
