  • Toxocariasis is one of the most common geohelminth infections in several parts of the world. We describe a rare case of ocular toxocariasis with secondary exudative retinal detachment treated with albendazole and an intravitreal dexamethasone implant. A 13-year-old boy with counting finger vision was diagnosed with retinal vasculitis and exudative retinal detachment in his right eye. Fundoscopic examination revealed retinal hemorrhage, retinal vasculitis, and exudative retinal detachment. Serological test using serum and intraocular aqueous humor were positive for anti-Toxocara specific IgG antibodies. He received repeated doses of intravitreal dexamethasone implants combined with oral albendazole. A sequential follow-up optical coherence tomography revealed that the retina was successfully reattached. His visual acuity subsequently improved to 20/400.

  • Brucella spp. are small, non-motile Gram-negative coccobacilli known to cause disease in a number of vertebrate species including humans and brucellosis is one of the world's major zoonoses, alongside bovine tuberculosis and rabies. There are about 33.55 million goats and 1.16 million sheep in Bangladesh. The sheep and goats can significantly play an important role in the economic well being of the resource-poor farmer in Bangladesh. Sexually matured 362 female small ruminants(300 goats and 62 sheep) were examined. Approximately 3-5 ml of blood was collected from the jugular vein of each animal and sera samples were prepared. Samples were then tested for brucellosis by using Rose Bengal test(RBT), plate agglutination test(PAT) and tube agglutination test(TAT). Among 362 small ruminants, irrespective of species(sheep or goat), diagnosed highest in TAT, 2.21%(n=8) and lowest both by RBT & PAT, 1.93%(n=7) and it is concluded that TAT is superior than RBT and PAT.

  • Microscopy is considered as the gold standard for malaria diagnosis although its wide application is limited by the requirement of highly experienced microscopists. PCR and serological tests provide efficient diagnostic performance and have been applied for malaria diagnosis and research. The aim of this study was to investigate the diagnostic performance of nested PCR and a recently developed an ELISA-based new rapid diagnosis test (RDT), NovaLisa test kit, for diagnosis of malaria infection, using microscopic method as the gold standard. The performance of nested-PCR as a malaria diagnostic tool is excellent with respect to its high accuracy, sensitivity, specificity, and ability to discriminate Plasmodium species. The sensitivity and specificity of nested-PCR compared with the microscopic method for detection of Plasmodium falciparum, Plasmodium vivax, and P. falciparum/P. vivax mixed infection were 71.4 vs 100%, 100 vs 98.7%, and 100 vs 95.0%, respectively. The sensitivity and specificity of the ELISA-based NovaLisa test kit compared with the microscopic method for detection of Plasmodium genus were 89.0 vs 91.6%, respectively. NovaLisa test kit provided comparable diagnostic performance. Its relatively low cost, simplicity, and rapidity enables large scale field application.

  • Along with a development of medical technology, a variety of tests, such as laboratory tests, x-ray and endoscopies are being used in health screening tests. As the tests determine the quality of health screening, test items and methods should be carefully selected. This study was to get hold of the test items of major health screening programs in Korea Most of the health screening programmes focused upon detection of risk factors and diagnosis of life - style related diseases (diabetes, hypertension, cardiovascular diseases, hypercholesterolemia, overweight, drinking, smoking, cerebrovascular diseases, osteoporosis) ,cancers (stomach, cervix, lung, breast, liver, colon, prostate, ovary, pancreas, thyroid, esophagus) , infectious diseases (hepatitis, tuberculosis, sexually-transmitted diseases, parasites) , chronic obstructive respiratory diseases, chronic renal diseases (bacteriuria hematuria, proteinuria) , anemia, glaucoma, hearing loss, Alzheimer disease, stress, early psychiatric diseases. The health screening tests were basic physical examination, basic laboratory tests (CBC, urinalysis, liver function tests, lipid tests, glucose, HbAlc, uric acid, electrolytes, serological tests (HBsAg, HBs-Ab, HCV-Ab, HIV-Ab, VDRL) EKG, x-ray (chest PA, CT) , endoscopy (gastroscopy, colonoscopy) , sonography(abdomen, thyroid, pelvis, breast) ,cytology (cervix) , bone density, tumor markets (NMP22, alpha-FP, CEA, CA-19-9, CA12S, PSA) and eye tests. Advanced technologies, like CT, PET, MRI, MRT/Angio, molecular testings) were widely used in hospital health screening programmes .In summary, a variety of tests were utilized in health screening in Korea. Those tests were utilized by stages or according to sex and age in most of health screening programmes, however a few program used tests to excess disregarding health screening subjects.

  • The determination of the accurate immune status of pregnant women is crucial in order to prevent congenital toxoplasmosis. Equivocal results with conventional serological techniques are not uncommon when IgG titers are close to the cut-off value of the test, so that a confirmatory technique is needed. For this purpose, we developed a homemade immunoblot (IB) using soluble extract of Toxoplasma gondii tachyzoites and assessed it by testing 154 positive, 100 negative, and 123 equivocal sera obtained from pregnant women. In order to select the more valuable bands in terms of sensitivity and specificity, we used the Youden Index (YI). The highest YIs were those given by the 32, 36, 98, 21, and 33 bands. The simultaneous presence on the same blot of at least 3 bands showed a much higher YI (0.964) and was adapted as the positivity criterion. The analysis of results showed that our homemade IB correlated well with the commercial LDBIO Toxo II $IgG^{(R)}$ kit recently recommended as a confirmatory test (96.7% of concordance).

  • We surveyed the antibody titers in the slaughtered pigs by enzyme immunodiffusion method for the epidemiological distribution of Aujeszky's disease in Korea. And also we observed the clinical symptoms, histopathological findings and antibody titers by serologic neutralization test in experimental animals infected with Aujeszky's disease virus(ADV) isolated from Korea. The results of the experiments were summarized as follows. 1. We detected 2 pigs infected with ADV of 1000 in 1990 and 1 of 600 in 1991 by enzyme immunodiffusion method. 2. In histopathological findings of experimental animals inoculated ADV, the typical characteristics of Aujeszky's disease were not observed in pig, but edema and degeneration in the epidermis were observed in rats, vasculoendotheriosis, perivascular cuffing and cellular infiltration in the cerebrum were appeared in rabbits and perivascular cuffing and forcal infiltration of glial cells in the cerebrum were appeared in mice. 3. The increasing antibody titers(1 : 64) in the serological neutralization test were ascertained in 2 carrier pigs inoculated ADV. 4. Rabbits, mice and rats died all about 5 days after inoculation, but pigs and chickens didn't die. 5. In 1 cat and 2 rabbits inoculated with the Aujeszky's disease virus(ADV), the typical clinical findings of Aujeszky's disease were observed in rabbit, but not in cat and so we slaughtered without any signs of Aujeszky's disease.

  • Objectives : This study was aimed at investigating liver protection mechanism of Cultivated Ginseng and Cultivated Wild Ginseng of Korean and Chinese by inducing liver toxicity through $CCl_4$ and t-BHP in mice and evaluated serological findings. Methods : Experiment groups was categorized into untreated normal group, treated control group, and orally administered Cultivated Ginseng and Cultivated Wild Ginseng of Korean and Chinese experimental groups. At the termination of experiment, gross examination of the liver as well as Total bilirubin, AST, and ALT contents in the serum were evaluated. Results : 1. In the $CCl_4$ induced acute hepatotoxicity test, total bilirubin, AST and ALT didn't show significant differences between the control and experimental groups. 2. In the t-BHP induced acute hepatotoxicity test, total bilirubin, AST and ALT didn't show significant differences between the control and experimental groups. Conclusion : Taken together, Cultivated Ginseng and Cultivated Wild Ginseng of Korean and Chinese cannot be effectively used for recovering the liver functions in acute hepatotoxicity tests using $CCl_4$ and t-BHP. Further researches, for example treated long period, must be tried to verify the efficacies.

  • In this experiment, we studied the sero-positive rate of akabane virus in cattle from Jeju-do and analyzed the seroepidemiological features. In an analysis of 1,051 samples, the positive rate for neutralizing antibody in sera collected in nine regions on Jeju-do was 56.7%. The rate varied with the region. The positive rate was 69.6% in Aewol, 63.1% in Jeju city, 54.4% in Anduck, 51.0% in Hallim, 69.8% in Jocheun, 47.6% in Pyosun, 40% in Daejeong, 30.0% in Harkyung, 71.6% in Namwon, 24.5% in Sungsan, 133.,3% in Seokypo and 44.5% in Gujwa, respectively The rate also depended on the age of the cattle. The positive rate was 67.2% in calves 0- to 12-month old, 48.3% in cattle 13- to 24-month old, 65.4% in cattle 25- to 36-month old, and 65.4% in cattle more than ,B7 months old. To isolate the virus from calves with malformations including arthrogryposis and hydranencephaly, cerebral homogenates were inoculated into Vero cells, which were determined for cytopathic effect (CPE). Vero cells with CPE were examined for Akabane virus using an electron microscope (EM) and indirect immunofluorescent antibody test (EM). Typical virus particles with a width of 90-130nm and specific immunofluorescence in the cytoplasm of infected cells were sought for identification.

  • This study was undertaken to establish reliable diagnostic-procedures for the microbiological monitoring of laboratory animals. Murine(mice and rats) antibodies against hemagglutinating virus of Japan(HVJ), mouse hepatitis virus(MHV) and Mycoplasma pulmonis(Mp) were detected sensitively and specifically in experimentally and naturally infected animals' sera by an indirect enzyme-linked immunosorbent assay(ELISA), using urease conjugated antimurine immunoglobulin. The sensitivity and specificity of the complement fixation test which has been apllied widely for serodiagnosis of HVJ, MHV and Mp infections were apparently lower than those of ELISA. From these results, the ELISA was found to be available for the serodiagnosis of HVJ, MHV and Mp infections in mice and rats.
