We investigated a small-scale serological survey to screen tissue-parasitic helminthiases of North Koreans as one of research programs for re-unification of Korea. Soil-transmitted helminthiases were found highly prevalent among North Korean residents at the border with China. ELISA using 4 tissue-parasitic helminth antigens was applied to 137 residents living in Cheongjin-shi, Hamgyeongbuk-do, North Korea and 133 female refugees in South Korea in 2004-2005. Among a total of 270 samples, 31 (11.5%), 25 (9.3%), and 11 (4.1%) were positive for specific IgG antibodies to antigens of Clonorchis sinensis, Taenia solium metacestode, and sparganum, respectively. The overall positive rate was 21.5%; 38.2% in males and 15.8% in females. The present finding suggests that tissue parasites, such as C. sinensis, T. solium metacestode and sparganum are highly prevalent in some limited areas of North Korea. These foodborne tissue-parasitic helminthiases should be considered for future control measures of parasitic diseases in North Korea.

This experiment was carried out to investigate the tendency of incident diseases in pre- and post- weaning piglets which ages were 1 to 7 weeks old by laboratory diagnosis and in order to minimize death in preweaning piglets and of stunted growth in postweaning piglets. The result of this experiment used as the basic data for the preventive programs in pre- and post- weaning piglets and were as follows: 23 different diseases diagnosed in 331 cases were studied in relation to age, season, and etiology. The most prevelent diseases of pre- and post- weaning piglet were Colibacillosis(79 case, 23.9%) and the major diseases were Salmonellosis(44 cases, 13.3%), Anemia(37 cases, 11.2%). Unknown viral disease(20 case, 6.1%), Rota viral infection(19 case, 5.8%), Porcine reproductive & respiratory syndrome(PRRS; 15 case 4.5%), Transmissible gastroenteritis(TGE; 12 case, 3.6%). The gastrointestinal disease, such as Colibacillosis, Salmonellosis, Swine dysentery, Clostridial infection, Rotaviral infection, TGE, Porcine epidemic diarrhea(PED) and Ballantidiosis occured pro- dominently in the period of pre- and post- weaning, which were 178 cases(53.8%) and not related to occurrence according to age and season. The respiratory diseases were Atrophic rhinitis(AR), Swine enzootic pneumonia, Pneumonic pasteurellosis, Pleuropneumonia, Branchopneumonia, PRRS and which were 48 cases(14.5%) and higher prevalent in spring and summer. The viral diseases was 73 cases(22.1%) that occurred in the period of 5 weeks piglet and prevalent mainly in spring. The bacterial diseases were 188 cases(56.8%) that were not related to occurrence according to age and season. Salmonellosis was prevalent in 3 to 5 weeks piglet and mainly occurred in summer. Viral septicemia and rotaviral infection occurred after 5 weeks piglets intensively and 3 to 5 weeks, respectively. And the both occurred without relation with season. PRRS occurred after 4 weeks piglet and prevalent in summer. TGE occurred 1 to 7 days old piglets and prevalent in spring and winter. Hematologic values of anemia was decrease in number of Red Blood Cell, concentration of Hemoglobin and Hematocrit. Amikacin, cephalothin, colistin, norfloxacin were effective to E coli, and amikacin, cephalothin, nortloxacin, neomycin were effective to Salmonellra spp. but clindamycin, erythromycin, penicillin, sulfonamides were resistant to E coli and Salmonella spp.

Objectives: Infectious diseases are known to be affected by climate change. We investigated if the infectious diseases were related to meteorological factors in Korea. Methods: Scrub typhus, hemorrhagic fever with renal syndrome (HFRS), leptospirosis, malaria and Vibrio vulnificus sepsis among the National Notifiable Infectious Diseases were selected as the climate change-related infectious diseases. Temperature, relative humidity and precipitation were used as meteorological factors. The study period was from 2001 through 2008. We examined the seasonality of the diseases and those correlations with meteorological factors. We also analyzed the correlations between the incidences of the diseases during the outbreak periods and monthly meteorological factors in the hyper-endemic regions. Results: All of the investigated diseases showed strong seasonality; malaria and V. vulnificus sepsis were prevalent in summer and scrub typhus, HFRS and leptospirosis were prevalent in the autumn. There were significant correlations between the monthly numbers of cases and all the meteorological factors for malaria and V. vulnificus sepsis, but there were no correlation for the other diseases. However, the incidence of scrub typhus in hyper-endemic region during the outbreak period was positively correlated with temperature and humidity during the summer. The incidences of HFRS and leptospirosis had positive correlations with precipitation in November and temperature and humidity in February, respectively. V. vulnificus sepsis showed positive correlations with precipitation in April/May/July. Conclusions: In Korea, the incidences of the infectious diseases were correlated with meteorological factors, and this implies that the incidences could be influenced by climate change.

Because the size of population was directly related to the power of the nation in the Chosun Dynasty, various efforts were exerted to maintain the size stable and the keys to the efforts were a high birth rate and a low death rate. However, in addition to wars, epidemic diseases had an enormous effect on the death rate. Particularly during the mid Chosun Dynasty, epidemic diseases were more prevalent than ever due to the abnormal climate called the little ice age. To cope with them, the government executed several medical relief policies and published medical books. In Chinese epidemiology, infectious diseases mean sicknesses caused by hot weather, but in Korean epidemiology, they indicate large-scale infectious sicknesses caused by both hot and cold weather. Therefore, as treatment methods for diseases from the cold were not applicable to the pathology of epidemic diseases, China developed separate epidemiology. In Korea, however, the main concern was how to prevent epidemic diseases, whether from hot or cold weather, that drove many lives into death. The characteristics of Korean epidemiology are as follows. First, whenever epidemic diseases were prevalent, in order to cope with them, translated medical books were promptly published including Ganibyeokonbang, Bunmunonyeokihaebang, Sinchanbyeokonbang, Byeokyeoksinbang and Byeokonsinbang. Second, those books were annotated in Korean so that people could read easily and accurately. Third, as an extension of the Hyangyak movement from the late Koryo Dynasty, Danbang was used a lot to treat and prevent epidemic diseases with less financial burden, and things obtainable easily according to individuals' situation were mentioned for anybody to overcome the emergent situation of epidemic diseases. Fourth, methods for praying to God were suggested for practitioners to work with sincere spirit and to keep themselves from epidemic diseases.

This study was performed to investigate the signalment, cause and clinical feature of corneal diseases of dogs in Korea. One hundred eighty-four dogs(273 eyes) with corneal diseases were examined and classified into congenital, inflammatory and metabolic diseases. Inflammatory diseases were subclassified into nonulcerative keratitis and ulcerative keratitis. The most prevalent corneal disease type was inflammatory disease(93.7%) and nonulcerative keratitis(58.6%) is more prevalent than ulcerative keratitis(35.1%) in the inflammatory diseases. The main cause of nonulcerative keratitis was keratoconjunctivitis sicca(19.0%) whereas that of ulcerative keratitis was trauma(9.9%). The most common breed with corneal disease was Shih Tzu(49.5%). The affected mean age was $6.4{\pm}4.1$ years old. The prevalence rate of corneal diseases were slightly higher in female(56.8%) than in male(43.2%). The data of corneal diseases in dogs obtained from this study will be utilized in prevention, diagnosis and treatment of corneal diseases in dogs and client education.
