The studies on the liver fluke of Korea have been reviewed. The fluke is Fasciola hepatica. Its intermediate host is Lymnaea biridis, whose principal habitats are rice paddies. The first fascioliasis of Korean native(beef) cattle was reported in 1915. Bovine fascioliasis is present throughout the conuntry, including north Korea, with the average prevalence of 30%. The prevalence of the disease is about the same in dairy cattle, which have been imported from other countries since 1960s. The disease was also found in Korea in other species of animals such as sheep, goats, deer of zoo and farms, and guinea pigs of a laboratory. Human fascioliasis was reported ; 35 cases by fecal examination and 11 by both parasitology and pathology. Of the latter 11 cases, 5 were ectopic parasitism. Economic loss due to the reduced carcass weight and milk production, and liver condemnation was great. Almost all flukicides developed in other countries are commercially available in Korea.

This study was designed to detect and evaluate an antigenicity of low molecular weight proteins of Fasciola hepatica in fascioliasis. Low molecular weight protein of F. hepatica was purified by ammonium sulfate precipitation and Sephacryl S-100 HR gel filtration. The protein obtained was estimated to be 8 kDa on 7.5-15% gradient sodium dodecyl sulfate gel electrophoresis. Immunoblotting studies showed that the 8 kDa protein reacted with human fascioliasis sera, but not other trematodiasis sera. This result suggests that the 8 kDa protein of F. hepatica is one of diagnostic antigens in human fascioliasis without cross-reaction with other human trematodiasis.

A 32-year old housewife, living in Seoul, recognized incidentally a painless mass at the left chest wall. During later 3 months, she experienced spontaneous swelling and regression of the mass repeatedly for 4 times. Surgical resection showed a granuloma at anterior serratus muscle containing a nearly matured adult of Fasciola species without vitellaria and uterus. This is the l1th human fascioliasis and the first extra-abdominal infection reported in Korea.

A 56 year-old Korean housewife/farmerlgoat keeper suffered from right upper quadrant pain and fever with chills. In the abdominal sonogram and computerized tomography, multiple, 2-3 cm, irregular shaped cavities were observed in the right lobe of liver. A liver biopsy revealed extensive central necrosis with Characot-Leyden crystals surrounded by palisading histiocytes, eosinophil-rich inflammatory infiltration. Worm was not observed. However, the serologic test for Fusciola-specific IgG antibody by micro-ELISA was positive. Prior antibody levels did not differ and eosionophilia persisted 6 and 16 months after praziquantel treatment although the cavitaxy lesions in the liver disappeared 6 months after the treatment. Reported herein is a human case of invasive fascioliasis diagnosed clinically by a combination of radiological, histopathological and serological studies.

A synthetic peptide was prepared based on the antigenic region of Paragonimus westermani pre-procathepsin L, and its applicability for immunodiagnosis for human paragonimiasis (due to Paragonimus heterotremus) was tested using an ELISA to detect IgG4 antibodies in the sera of patients. Sera from other helminthiases, tuberculosis, and healthy volunteers were used as the references. This peptide-based assay system gave sensitivity, specificity, accuracy, and positive and negative predictive values of 100%, 94.6%, 96.2%, 100%, and 88.9%, respectively. Cross reactivity was frequently seen against the sera of fascioliasis (75%) and hookworm infections (50%). Since differential diagnosis between paragonimiasis and fascioliasis can be easily done by clinical presentation and fascioliasis serology, this cross reaction is not a serious problem. Sera from patients with other parasitoses (0-25%) rarely responded to this synthetic antigen. This synthetic peptide antigen seems to be useful for development of a standardized diagnostic system for paragonimiasis.

Fascioliasis is a foodborne zoonotic parasitic disease. We report 4 cases occurring in the same family, in whom diagnosis of acute fascioliasis was established after series of tests. One case was hospitalized with fever, eosinophilia, and hepatic lesions. MRI showed hypodense changes in both liver lobes. The remaining 3 cases presented with the symptom of stomachache only. Stool analysis was positive for Fasciola eggs in 2 adult patients. The immunological test and molecular identification of eggs were confirmed at the National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, Shanghai, China. The results of serological detection were positive in all the 4 patients. DNA sequencing of PCR products of the eggs demonstrated 100% homology with ITS and cox1 of Fasciola hepatica. The conditions of the patients were not improved by broad-spectrum anti-parasitic drugs until administration of triclabendazole.

The authors would record the fifth case of human fascioliasis in Korea, occurring in a 48 year old Korean man who lived in Munkyong, Kyongsangbuk-do. The diagnosis was based on the morphology and measurements of the eggs which were collected in necrotic debris from the tunnel-like ulcerations of the gallbladder wall which was surgically removed for a gall stone. Although we failed to find out the fluke in the specimen, there found an evidence of once presence of Fasciola in the inflamed wall of the gallbladder in this patient.

We report here an ectopic case of Fasciola hepatica infection confirmed by recovery of an adult worm in the mesocolon. A 56-year-old female was admitted to our hospital with discomfort and pain in the left lower quadrant of the abdomen. Abdominal CT showed 3 abscesses in the left upper quadrant, mesentery, and pelvic cavity. On surgical exploration, abscess pockets were found in the mesocolon of the sigmoid colon and transverse colon. A leaf-like worm found in the abscess pocket of the mesocolon of the left colon was diagnosed as an adult fluke of F. hepatica. Histologically, numerous eggs of F. hepatica were noted with acute and chronic granulomatous inflammations in the subserosa and pericolic adipose tissues. Conclusively, a rare case of ectopic fascioliasis has been confirmed in this study by the adult worm recovery of F. hepatica in the mesocolon.

Human Fasciola hepatica infection is a rare entity involving infestation of the liver and biliary tree with adult flukes. which can result in hepatitis. cirrhos is and biliary tract inflammation. obstruction and lithiasis. The patient had the typical diagnostic tetrad of fever. eosinophilic leukocytos is. tender hepatomegaly and fluke ova in the stools. Theatment consistes of Emetine hydrochloride administration for hepatic involvement and common bile duct exploration for removal of flukes. with cholecystectomy for associated cholelithiasis. The combination of medical and surgical therapy cal be expected to produce an arrest of this infection. The removed liver revealed eggs of the fasciols species in the intrahepatic bile duct. The clinical history. pathological findings and treatment of this case were described.

In order to know the species and frequency of human parasitic infection diagnosed by biopsy, 149 cases (0.18%) of parasitic infection were reviewed, which were selected from 80,947 biopsied materials submitted for routine histopathological examination during a period of 10 years from 1980 to 1989 at Department of Pathology, Chonnam National University Hospital. They consisted of 112 cases of cysticercosis, 17 paragonimiasis, 7 clonorchiasis, 4 amebiasis, 1 sparganosis, 1 enterobiasis, 1 anisakiasis, and 1 fascioliasis respectively Based on morphological preservation of cysticercus, they could be divided into mild (20.2%), moderate (40.4%), and severe (39.4%) degeneration. Except 2 cases biopsied at the lungs, 15 cases of ectopic paragonimiasis were located at abdominal cavity (8 cases) and central nervous system (7 cases). One case of intrahepatic fascioliasis was observed. This is the 13th human fasciollasis reported in Korea. From the above results, the frequency of parasitic infections found in biopsied specimens was on the decrease as the year passed by, but biopsy is very useful diagnostic method on tissue parasites such as cystlcercosis and ectopic paragonimiasis.
