Swine sera collected from January to December 2000 were tested for the survey on transmissible gastroenteritis(TGE) infection in Gyeongbuk province. Serum neutralization(SN) test was peformed in finishing pigs of 50 pigs industry without clinical signs of TGE and sows, gilts and growing pigs of four pigs industry with TGE. As the results of SN test in fifty industry, antibody titers of 90.6%(474/523 samples) showed below 4. Antibody titers of them showed highly in two pigs industry of western region and three pigs industry of southern region of Gyeongbuk province. The results indicated that TGE had been occurred before in five pigs industry. Most of antibody titers showed of highly in four pigs industry having had TGE. There were no significant differences of the antibody titers of TGE according to age when the survey was made. The above results indicated that the pigs of Gyeongbuk province were not almost exposed in porcine respiratory coronavirus(PRCV) by present.

This experiment was performed to investigate the leptospiral antibody in dairy cattle with serological test in three areas of Kangwondo from February to June, 1995. Twelve different living antigen's (S icterohemorrhagiae, Lpomona, L hardjo, L australis, L canicola, L autumnalis, L grippotyphosa, L tarassovi, L pyroenes, L bataviae, L hebdomadis and L ballum) of Leptospira interrogans were used for the serological test in dairy cattle. The blood samples of 130 cattle were examinde by microscopic agglutination test. Among the serum samples of the dairy cattle, 5 heads of the dairy cattle (3.8%) were positive. Among the positive samples of 5 heads, 3 heads of dairy cattle (2.3%) showed the antibody of L canicola, 2 heads of dairy cattle (1.5%) showed the antibody of L icterohaemorrhagiae. Positive rate by age was 0% ($\leq $2year), 4.6% (3~4year) and 6.6% ($\geq $5year).

We prepared antibodies from insect glycosaminoglycans (GAGs) and assayed the titer. Nine polyclonal antibodies against insect GAGs were raised for development of an ELISA in biological fluids (mice serum). The 3th booster collection of antiserum of BALB/c mice as a primarily antibody was assayed for titer determination by ELISA method. In sandwich ELISA of GAGs derived from Isaria sinclairii or other insects, antiserum from insect GAGs gave satisfactory results for so potent antibody(100: 1~1000:1) raising (manufacturing) agent in range of 10 ng/ml.

The study was taken to analyze the laboratory findings of the 161 patients with autoimmune thyroiditis treated at Kyungpook University Hospital from January 1992 to July 1993. They were all female and mean age was 33 years ranging from 10 to 73 years. Mean radioactive iodine uptake(RAIU) of the thyroid was $30.90{\pm}21.80(mean{\pm}SD)%$ at 6 hours and $37.97{\pm}23.25%$ at 24 hours. Mean serum levels of thyroid hormones were $1.41{\pm}0.48$(ng/ml) of T3, $7.26{\pm}3.23$(ug/dl) of T4, and $1.11{\pm}0.66$(ng/dl) of free T4, while mean serum level of TSH was $17.99{\pm}30.72$(uIU/ml). Mean levels of serum autoantibodies were 24. $43{\pm}31.91$(U/ml) of antithyroglobulin antibody and $55.32{\pm}41.97$(U/ml) of antimicrosomal antibody. The correlation between RAIU and serum thyroid hormone levels was significantly negative, but the positive correlation between RAIU and serum TSH was noted. The correlation between thyroid hormones and TSH was significantly negative, but the positive correlation between RAIU and serum TSH was noted. The correlation between thyroid hormones and TSH was significantly negative, while antimicrosomal antibody titer revealed significantly positive correlation with TSH. The RAIU and free T4 showed negatively correlated with the increasing age. The Initial clinical findings of the patients with autoimmune thyroiditis revealed euthyroidism in 83.2%, hypothyroidism in 14.9%, and hyperthyroidism in 1.9%. The incidence of abnormally increased serum thyroglobulin, antithyroglobulin antibody, and antimicrosomal antibody were 21.3%, 97.5%, and 87.6%, respectively and these abnormalities were more frequent in the patients with documented clinical thyroid functional disturbances.

Development of a solid-phase chemiluminescence immunoassay for the detection of progesterone in serum extract was described. The chemiluminescence immunoassay was establised utilizing anti-progesterone monoclonal antibody that coated on polystyrene tubes and progesterone-ABEI conjugate as tracer. The light yield generated from antibody bound conjugate was counted on clinilumat luminometer by oxidation with microperoxidase and peroxide. The chemiluminescence immunoassay was high specific and accurate and detects as little as 3.9ng/ml of progesterone. The intra-assay CV ranged from 6% to 11.5% and inter-assay CV ranged from 13.6% to 18.7%. This assay system was good correlated with conventional kit radioimmunoassay system (r=0.98).

A one-step, two-site enzyme immunoassay was developed for measuring human alpha-fetoprotein (AFP) in serum and amniotic fluid using monoclonal antibodies (McAb) by eliminating the high-dose hook effect. Three McAbs that recognize different epitopes were selected among 16 different clones on the basis of epitope mapping, two for immobilization and one for horseradish peroxidase conjugation. This one-step immunoassay system is more convenient and rapid compared to a conventional two-step sandwich immunoassay system. It did not exhibit the hook effect to around 2.7 mg/ml of AFP, which is probably one of the highest concentrations of AFP in the serum. The dose-response curve of the system was linear to 500 mg/ml of AFP and the system could differentiate as low as 1 mg/ml of AFP The intra- and inter-assay variations were in an acceptable range; 95~104% and 97~105% respectively Its correlation with other commercial systems was around 95%.

Liver abscess in children is rare in developed countries; the incidence is 25 per 100,000 admissions in USA. Common complications are pleural effusion, empyema, pneumonitis, hepatopleural or hepatobronchial fistula, intraperitoneal or intrapericardiac rupture, septic shock, cerebral amebiasis, etc. These complications may lead to death if the management is delayed. However, recent management results in a mortality of less than 15%. We report a case of liver abscess in a child. He manifested with fever and abdominal pain in the right upper quadrant. On computerized tomography scans, multiple cystic lesions were seen in both lobes of the liver and were 5 to 55 mm in size. In laboratory findings, neutrophilic leukocytosis, peripheral eosinophila, elevated values of ESR, C-reactive protein, and elevated serum AST, ALT, ALP and GGT were detected. Furthermore, we determined the organisms in the blood culture and serum. Blood culture was positive for Streptococcus spp., and amebic indirect hemagglutination antibody titer was increased to 1:512.
