경상북도 영덕군의 하천에 서식하는 점몰개 spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon)의 근육에서 새인두흡충 Clinostomum complanatum (Rudolphi, 1814)의 피낭유충이 발견되었다. 감염된 점몰개는 "yellow grub"인 기생충의 피낭유충으로 인해 표면이 울퉁불퉁하게 보였으며, 수면위에 힘없이 유영하였고 일부 폐사한 개체도 발견되었다. 분리된 탈낭유충의 형태는 혓바닥 모양이었으며, 크기는 2.85~5.89 mm×0.8~1.99 mm였다. 어체당 1~98 개의 피낭유충을 분리하였으며 평균 감염수는 25개로 나타났다. 특히, 성어크기인 평균 7 cm 정도의 점몰개는 100% 감염되어 있었다. 본 연구는 한국의 자연수계에 서식하는 어류에서 C. complanatum 의해 질병이 발생하고 폐사가 일어난 첫 보고이다. The metacercariae of Clinostomum complanatum (Rudolphi, 1814) were isolated in the whole body muscle of wild freshwater fish, spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon) from the local river in Yeongdeok, Gyeongsangbuk-do, Korea. The infected fish with bumpy body surface by "yellow grub" showed erratic swimming behavior and some fish were died. The isolated excysted metacercariae were tongue shaped and 2.85~5.89 mm × 0.8~1.99 mm in size. 1~98 metacercariae were isolated in individual fish and mean infection intensity was 25. All examined adult spotted barbel gudgeon sizing 7 cm in body length were infected. This is the first report of disease outbreak and mortality caused by C. complanatum infection in wild freshwater fish in Korea.

E. coli rnpB gene의 발현에 영향을 미치는 M1 RNA structural gene의 부분을 조사하였다. P-1 promoter 에서 합성되는 RNA의 5' 부분이 이루는 이차구조를 분석한 결과 +1 에서 부터 +72 까지에 존재하는 hairpin loop 구조가 rnpB gene의 발현에 중요한 역할을 하는 것으로 밝혀졌다.

Hepatic cirrhosis is a common response to chronic liver injury from many causes and is one of the most common cause of all deaths. This study was carried out to develop a suitable experimental hepatic cirrhosis in rats to understand this disease and to apply for the pharmacokinetic in disease state. Following three kinds of experimental models were induced; 1)Bile duct ligation/scission (BDL/S), 2) N,N-dimethylnitrosamine(DMN), 3)Carbon tetrachloride. The hepatic cirrhosis was characterized by examining the liver/body weight ratio, serum biochemical values, hydroxyproline content in liver and histological appearance in cirrhotic rat liver(hematoxylin & eosin). The results are as follows : (1) In BDL/S, the liver was enlarged to 250% of normal liver. In contrast the liver was shrinked to 48% and 78% of the normal liver in DMN and CCI₄, respectively. (2) In CCI₄ and BDL/S, the serum ALT, AST, ALP and total bilirubin levels were significantly increased to 200-300% of normal level, while ALT and total bilirubin level were significantly increased in DMN group. (3) Hydroxyproline content in cirrhotic rat liver was significantly 200-500% higher than that of normal liver. (4) Nodular formation with fibrosis was observed in BDL/S, DMN, CCI₄ induced cirrhotic rat liver.

To improve administration of ketolorac tromethamine, we prepared matrix tablets with Eudragit (RS 100 or 30D), diluents (avicel:lactose=l:l or Ca phosphate) and Mg stearate using wet-granulation method. Sustained release matrix tablets using Eudragit® RS 100 7 and 10% decreased dissolution rate at pH 1.2 and 68 Ca. phosphate as diluents showed more decreased dissolution rate than that of avicel:lactose (1:l). Sustained release matrix tablets using Eudragit® RS 30D also showed very effective sustained release of KT.

Obesity is defined as an excess of body fat and is closely related to diabetes, hypertension and heart disease. Dietary cure has been paid attention as a method for preventing from or curing obesity. The effect of some food products developed in this laboratory, such as, functional saengsik (Health & Joy saengsik), diet food (Health & Joy diet meal) and intestine function activator (Cell-pa, commercial name) on curing and protecting from obesity were investigated. Diet program was applied to 31 adults (Males 22, Females 9) with above 120% body mass index (BMI). After diet program was applied, body weight, body fat and fat weight decreased by 1, 4.8 and 4.5% (p<0.01), HDL-cholesterol increased by 3.6% and LDL-cholesterol and atherogenic index decreased by 6.6 and 7.7% (p<0.05). Consequently, the food products developed in this laboratory effectively reduced the obesity.

To assess the functional significance of long axis movement which would reflect the fiber orientation of the ventricular muscle, we examined the mitral annulus motion and compared it with standard minor axis movement. M-mode echocardiogram were performed in 24 healthy individuals and 17 mitral valve replaced (MVR) patients with simultaneous EKG and phonocardiogram recordings. The results were as follows : 1. In the controls, the onset of shortening of long axis preceeds that of minor axis (phase difference : 20±3msec, mean± SEM) but in MVR patients this phase difference was reversed (-33±8msec). It means that the spherical shape changes which can be observed in normal controls during isovolumic contraction period were lost in MVR patients. 2. In MVR patients, the time intervals from A2 to the end of shortening of long axis were significantly delayed compared with normal controls (54±3 VS 90±8 msec, P<0.01). 3. In MVR patients, the delayed shortening of long axis was observed in amplitude as well as in time. In summary. we observed the regional nonuniformity between long axis and short axis in normal control and interpreted that it could play a role in modulating ventricular function which was lost in MVR patients.

This paper proposed a design technique of multimedia document editing system by using object-oriented methodology and its implementation using object-oriented language. The multimedia document editing system can generate a mixed document which consists of text, image, graphic and video, verifying the results by formatting document and process the information of position per page. The hierachical structured design of the class library is proposed where document processing methodolgy and object-oriented one are employed. The system is implemented with Turbo C++ package which provides object-oriented compiling function on a PC.
