  • A highly endemic focus of human infection with Heterophves nocens (Heterophyidae) was discovered from a small coastal village of Shinan-gun, Chollanam-do, for the first time in Korea. Fecal examinations by cellophane thick smear and formalin- ether sedimentation techniques revealed 42.9% heterophyid egg Positive rate out of 98 inhabitants examined. It was difficult to confirm the species of heterophylds only by eggs. In order to collect the adult flukes, the egg Positive cases were treated with 10 mg/kg single dose of praziquantel and purged with magnesium sulfate, and the adult worms were collected from the diarrheic stools. From each of 18 cooperative patients 1 to 1,124 (total 4,730) H. nocens worms were recovered, together with a few to large numbers of heterophyids (Pvginiopsis summa, Stictonora juscatunl and for gymnophallids (Gvmopholloides stool) . It is speculated that H. nocen might be widely distributed along the southwestern coastal areas where the brackish water fish such as the mullets or gobies are popularly eaten raw.

  • 렉틴(Lectins)은 세포막의 당단백질의 과당류 말단기에 특이적으로 결합하는 비면역성의 당단백질 혹은 단백질을 말하는데 정상세포와 변형된 세포에서 렉틴반응의 차이가 남으로써 요즘에는 렉틴을 병리학적 진단에 이용 가능하게 되었다. “Loss of contact inhibition”은 세포 악성화의 중요한 특징으로 세포의 악성화는 세포막의 구조의 변화와 관계가 있을 것으로 알려져 왔으며 1989년 후두암에서 PNA의 반응이 양성 반응을 나타낸다고 보고되어 저자들은 7가지의 렉틴을 이용하여 후두암전구증의 하나인 후두각화증에서 이형성(Atypia)의 존재유무에 따른 렉틴 반응의 변화를 알아보고자 본 연구를 시행하여 다음과 같은 결과를 얻었다. 1. 이형성이 없는 단순 후두각화증에서는 Con A와 WGA만이 기저세포에 반응이 있었으며, 후두각화증의 가장 중요한 부위인 극세포층에서는 WGA, RCA-I, PNA, SBA, UEA-I, DBA가 세포질에는 반응이 없이 세포간교에만 염색이 되는것을 관찰할 수 있었고 Con A는 반대로 극세포층의 세포질에 반응을 하였으나 세포간교에는 반응이 없었다. 2. 이형성을 동반한 후두각화증에서, 기저세포에서는 반응의 차이가 없었고 극세포층에서는 UEA-I, RCA-I. WGA, PNA, SBA는 세포간교에서 반응이 나타나지 않았고 세포질에서 양성 반응을 관찰 할 수 있었으며 DBA, Con-A에서는 반응의 차이를 관찰 할 수 없었다. 따라서 후두각화증의 극세포층 세포막에서 UEA-I, RCA-I, WGA, PNA, SBA 반응의 소실은 후두암으로의 진행과 밀접한 관계가 있는 이형성의 존재를 암시한다하겠다.

  • 말기 폐기종 환자의 치료에 있어서 폐이식술은 최근 5년 생존율의 향상으로 점점 확대외어 가는 추세이다. 또한 이식폐의 부족으로 일측 폐이식술이나 이형 혈액형에서의 폐이식술의 시행이 늘고 있는 추세이다. 이형 혈액형에서의 폐이식은 술후 적절한 면역 억제제의 투여로 동형 혈액형에서의 폐이식술에서와 마찬가지로 좋은 결과를 보이고 있다. 저자들은 말기 폐기종으로 호흡 곤란이 심해져 가는 35세 A형 여자 환자에 O형 남자 환자의 좌측 폐를 이식하였다. 술후 면역 억제를 위해 3제 치료(싸이클로스포린, 아자씨오프린, 프레드니졸론)를 실행하였고 수술 중에 항CD3항체(OKT3)를 1회 투여하여 이식 거부 반응을 억제할 수 있었다. 환자는 술후 특별한 문제 없이 18일째에 퇴원할 수 있었다.

  • Pungitius sinensis specimens were collected from the Namdae River and Chusu River drained into Sea of Japan, and their morphological characters were investigated to determine if this species shows sexual dimorphism. The ratio of the head length to the body length revealed marked sexual difference; the head length in males was longer than in females. The snout length and body depth at anus showed a tendency to be larger in males than in females. This dimorphism seems to be related to breeding habits. The ethological significance of the larger head of males was discussed.

  • In this study, effects of demolding temperature (DT) on the formability and optical properties were evaluated in order to optimize thermal nanoimprint lithography for anti-reflective film. Characterization on optical property showed that optical performance was gradually enhanced as the DT increased up to $70^{\circ}C$ while the transmittance and the reflectance was degraded as the DT increased further to $100^{\circ}C$. In addition, similar behavior was observed from formability analysis. It was contributed to the formation of free volume and viscose flow. Therefore, it was concluded that the formability and optical property are highly influenced by the formation of free volume and viscous flow of polymer depending on the DT.

  • Fibrous dysplasia is a condition characterized by the replacement of the medullary component of predominantly long bone with fibrous tissues. The monostotic form of the fibrous dysplasia occurs more frequent than the polyostotic form. Only the twenty three previous cases of vertebral involvement in monostotic fibrous dysplasia have been reported. Authors experienced a case of monostotic fibrous dysplasia of the third lumbar vertebra, so we report this case. Report details the diagnosis and treatment of a 34 years old man with back pain from monostotic fibrous dysplasia of the third lumbar vertebra. We discuss the experience in the consideration of previous report to recommend the optimal management of this disease.

  • This study was carried out to investigate the distribution and characteristics of off-type rice plant in farmer's paddy field. The ratio of the field contaminated by off-type rice was highest in the southwestern area, followed by the southeastern area, the central area in Korea. The occurrence density of off-type rice was higher in the southern area than the central area. The short-grain red rice was the most dominant off-type rice group, followed by extremely late and sterile rice group and long-grain red rice group in Korea. The long-grain red rice group was dominant in Jeonnam and Kyongnam, and the extremely late and sterile rice group was dominant in Jeonbuk, and the short-grain red rice group in the other provinces. The culm length of most off-type rice groups growing in the farmer's paddy fields was longer than the farmer's cultivars, and the long-grain red rice group and the short-grain red rice group were especially longer. The number of spikelets per panicle of the off-type rice groups were generally greater than the farmer's cultlvars, and in particular, the extremely late and sterile rice group and the long-grain normal rice group had more spikelet per panicle. Most of the off-type rice groups were extremely sterile.

  • A 4-years-old, intact male Golden retriever dog was presented with abdominal distension and dyspnea. Physical examination revealed arrhythmia and cardiac murmur. Generalized cardiomegaly, pleural effusion and ascites were shown on thoracic and abdominal radiographs. Two-dimensional echocardiography revealed abnormal mitral and tricuspid valve motion, mitral and tricuspid regurgitation, left ventricular eccentric hypertrophy and left atrial dilation. Color-flow Doppler imaging revealed turbulent flow extending into the left ventricle during diastole from the mitral valve orifice, and into the left atrium during systole. Spectral Doppler recordings revealed highly increased early diastolic mitral valve inflow and prolonged pressure half-time of mitral inflow. Based on the echocardiographic examination, the diagnosis was made as the mitral valve dysplasia concurrent with mitral valve stenosis and tricuspid valve dysplasia.
